In the title of columns produced in Russia, the LDV letters are often present: this is a water heating device (c) flowing (P) gas (g). The figure, standing after the letters of the WSV, indicates the thermal power of the device in kilowatts (kW). For example, WSG-23 apparatus Water heating flow gas thermal power of 23 kW. Thus, the name of the modern columns does not define their design.
WGV-23 water heater was created on the basis of WGV-18 water heater, produced in Leningrad. In the future, VSV-23 was produced in the 90s on a number of enterprises of the USSR, and then there is a number of such devices in operation. Separate nodes, for example, the water part, finds use in some models of the modern speakers of the Neva.
The main technical characteristics of HPV-23:
- thermal power - 23 kW;
- performance when heated at 45 ° C - 6 l / min;
- minimum water pressure - 0.5 bar:
- maximum water pressure - 6 bar.
HPV-23 consists of a gas supply, heat exchanger, the main burner, block-crane and solenoid valve (Fig. 74).
The gas feeder serves to feed the combustion products into the smoke line of the speaker. The heat exchanger consists of a carrier and a fire chamber, stuck with a cold water coil. The height of the fire chamber HPV-23 is less than that of KGI-56, because the burner of HVV provides better stirring of gas with air, and the gas burns out a shorter flame. A significant number of HSV columns has a heat exchanger consisting of one caner. The walls of the fire chamber in this case were made of steel sheet, the serpent was absent, which made it possible to save copper. The main burner is multi-meter, it consists of 13 sections and a collector interconnected by two screws. Sections are collected in a single integer with the help of tie bolts. The collector has 13 nozzles, each of which is placed gas in its section.
The block crane consists of gas and water parts connected by three screws (Fig. 75). A gas part of a block-crane consists of a housing, valve, crane tubes, a gas crane cap. The case is pressed by the conical liner for the gas crane cork. The valve has a rubber seal along the outer diameter. Top on it presses the conical spring. The saddle of the safety valve is performed in the form of a brass liner pressed into the housing of the gas part. The gas crane has a handle with a limiter, which fixes the opening of the gas supply of PA steam. The crane tube is pressed against the cone's liner with a large spring.
On the crane tube there is an outlet for gas supply to the stall. When the crane is rotated from the extreme left position at an angle of 40 °, the velocity coincides with the gas supply hole, and the gas begins to enter the stall. In order to supply gas to the main burner, you need to press the crane knob and turn on.
The water part consists of lower and upper caps, venturi nozzles, membranes, plates with a rod, ignition retarder, rod gland and clamping rod sleeve. The water is supplied to the water part on the left, enters the subable space, creating pressure in it equal to the pressure of water in the water supply. Having created the pressure under the membrane, water passes through the nozzle of Venturi and rushes to the heat exchanger. Veenturi nozzle is a brass tube, in the narrower part of which four through holes are made, which come out in the outer circular pump. The outlet coincides with through holes that are available in both water part lids. For these holes, the pressure from the narrowest part of the venturi nozzle is transmitted to the above space. The stock of the plate is compacted with a nut, which squeezes the gland from fluoroplastic.
It works automatics by water fluid as follows. When water passes through the nozzle of the Venturi in the narrow part of the highest speed of water and, therefore, the smallest pressure. This pressure is transmitted through through holes into the dummy cavity of the water part. As a result, the pressure difference appears under and over the membrane, which is strung up and pushes a plate with a rod. The rod of the water side, resting in the gas rod of the gas part, raises the valve from the saddle. As a result, the gas pass on the main burner opens. When the flow of water is stopped, the pressure under and over the membrane is aligned. The cone spring presses on the valve and presses it to the saddle, the gas supply to the main burner is stopped.
The solenoid valve (Fig. 76) serves to disable the gas supply during the swelling of the fist.
When you press the solenoid valve button, its rod rests on the valve and moves it from the saddle, while squeezing the spring. At the same time, anchor presses against the electromagnet core. The gas begins to flow into the gas part of the block-crane. After the ignition of the repliment, the flame begins to heat the thermocouple, the end of which is installed in a strictly defined position in relation to the stobnant (Fig.77).
The thermocouple that occurred when thermocouples is heated to wind the electromagnet core. In this case, the core holds anchor, and with it the valve, in the open position. The time for which the thermocouple produces the necessary thermo-emf and the electromagnetic valve begins to hold the anchor, is about 60 seconds. With the swelling, the stamp of the thermocouple cools and ceases to produce the voltage. The core no longer holds the anchor, under the action of the spring the valve closes. The supply of gas and the stall, and the main burner is stopped.
Automatics by traction turns off the gas supply to the main burner and the stall in the violation of the thrust in the chimney, it works on the principle of "gas removal from the stobble". Automation by traction consists of a tee, which is attached to the gas part of the block-crane, tube to the thrust sensor and the sensor itself.
Gas from the tee is served to the stober, and to the thrust sensor installed under the gas travelers. The thrust sensor (Fig. 78) consists of a bimetallic plate and fitting, reinforced with two nuts. The upper nut at the same time is a saddle for a plug, overlapping the outlet from the fitting. A tube supplying gas from a tee is attached to the fittings of the cape nut.
With normal thrust, combustion products go into chimney, without heating the bimetallic plate. The plug is tightly pressed to the saddle, the gas from the sensor does not exit. With violation of thrust in chimney, combustion products are heated by a bimetallic plate. It is strung up and opens the gas outlet out of the fitting. The gas supply to the stall decreases sharply, the flame stops normally heat the thermocouple. It cools and ceases to produce tension. As a result, the electromagnetic valve closes.
Repair and service
The main malfunctions of the WSG-23 column include:
1. The main burner does not light up:
- little water pressure;
- deformation or plowing membranes - replace the membrane;
- venturi nozzle is clogged - Clean the nozzle;
- the rod from the plate was taken away - replace the rod with a plate;
- skale of the gas unit with respect to water - align with three screws;
- the rod moves badly in the gland - lubricate the rod and check the nuts tight. If weaken the nut more necessary, the flow of water from under the sealance is possible.
2. When the water intake is stopped, the main burner does not fuck:
- under the safety valve fell pollution - clean the saddle and valve;
- weakening the cone spring - replace the spring;
- the rod moves badly in the gland - lubricate the rod and check the nuts tight. If there is a flame, the stamp electromagnetic valve is not held in the open position:
3. Disruption of the electrical circuit between the thermocouple and the electromagnet (break or short circuit). The following reasons are possible:
- the lack of contact between the terminals of the thermocouple and the electromagnet is to clean the terminals using the sandpaper;
- the insulation disorder of the copper wire of thermocouple and a short circuit of it with a tube - in this case, the thermocouple is replaced;
- violation of the insulation of turns of the coil of an electromagnet, closing them between themselves or on the core - in this case, the valve is replaced;
- violation of the magnetic chain between the anchor and the core of the electromagnet coil due to oxidation, dirt, fatty film, etc. It is necessary to clean the surface with a flap of coarse tissue. It is not allowed to stripping surfaces with appliances, emery paper, etc.
4. Insufficient heating Thermocouple:
- the working end of the thermocouple has jumped up - remove the soot from hot spoil thermocouples;
- the nozzle of the stagnant was clogged - to clean the nozzle;
- the thermocouple is incorrectly installed relative to the stobble - to establish the thermocouple relative to the stamp so as to ensure sufficient heating.

Flowing water heater WSV-23
1. Non-prior view on ecological and economicgas Industry Problems
It is known that Russia is the richest gas in the world's gas reserves.
Environmentally natural gas is the cleanest type of mineral fuel. When combustion, it produces a significantly smaller amount of harmful substances compared to other types of fuel.
However, burning humanity of a huge number of different types of fuel, including natural gas, over the past 40 years has led to a noticeable increase in carbon dioxide content in an atmosphere, which, like methane, is greenhouse gas. Most scientists are this circumstance consider the current warming of climate.
This problem has alarmed public circles and many statesmen after entering the book in Copenhagen Books "Our General Future" prepared by the UN Commission. It was reported that climate warming can cause the melting of the ice of the Arctic and Antarctica, which will lead to an increase of the world's ocean level, the flooding of island states and constant coasts of continents, which will be accompanied by economic and social shocks. To avoid them, it is necessary to dramatically reduce the use of all hydrocarbon fuels, including natural gas. On this issue, international conferences were convened, intergovernmental agreements were made. The atomicists of all countries have become the advantages of atomic energy destructive for humanity, the use of which is not accompanied by the extraction of carbon dioxide.
Meanwhile, the alarm was in vain. The fallacy of many predictions, data in the mentioned book is related to the lack of natural scientists in the UN Commission.
Nevertheless, the issue of increasing the level of the world's ocean was carefully studied and discussed at many international conferences. It revealed. That in connection with the warming of climate and melting of the ice, this level is really rising, but at a speed not exceeding 0.8 mm per year. In December 1997, at a conference in Kyoto, this figure was clarified and turned out to be 0.6 mm. So in 10 years, the ocean level will rise by 6 mm, and in a century, 6 cm. Of course, this figure to frighten anyone should.
In addition, it turned out that the vertical tectonic movement of coastal lines by an order of magnitude exceeds this value and reaches one, and even two centimeters per year. Therefore, despite the rise of 2 oceans levels, the sea in many places of melts and retreats (the North of the Baltic Sea, the coast of Alaska and Canada, the Chile coast).
Meanwhile, the global climate warming may have a number of positive consequences, especially for Russia. First of all, this process will contribute to an increase in water evaporation from the surface of the seas and oceans, the area of \u200b\u200bwhich is 320 million km. 2 climate will become more wet. Reduced and, drought can be ceased in the Lower Volga region and in the Caucasus. Start slowly move towards the north the border of agriculture. Significantly ease of swimming in the Northern Sea Route.
Reduced expenses for winter heating.
Finally, it is necessary to remember that carbon dioxide is food for all earth plants. It is precisely processing it and highlighting oxygen, they create primary organic matter. Back in 1927 V.I. Vernadsky pointed out that green plants could process and convert much more carbon dioxide into organic matter than the modern atmosphere can give. Therefore, it recommended the use of carbon dioxide as a fertilizer.
Subsequent experiments in phytotron confirmed forecast V.I. Vernadsky. When growing in conditions of a double carbon dioxide carbon dioxide, almost all cultural plants grew faster, fruiting 6-8 days earlier and brought a crop at 20-30% higher than in control experiments with its usual content.
Consequently, agriculture is interested in enriching the atmosphere with carbon dioxide by burning hydrocarbon fuels.
It is useful to increase its content in the atmosphere and for more southern countries. Judging by Paleographic data, 6-8 thousand years ago during the so-called Holocene climatic optimum, when the average annual temperature on the latitude of Moscow was 2C above the present in Central Asia, there was a lot of water and there was no desert. Zeravshan fell into Amarya, r. Chu fell in Syrdarya, the level of the Aral Sea stood at +72 m and the United Central Asian rivers flowed through the current Turkmenistan to the deflection of the Southern Caspian. Sands of Kyzylkum and Karakum is the displeased later river alluvium of the recent past.
And the sugar whose area is 6 million km 2, also presented at this time not the desert, but a savanna with numerous herds of herbivores, full-flow rivers and settlements of the Neolithic man on the shores.
Thus, the burning of natural gas is not only economically 3 profitable, but also from an ecological point of view, because it contributes to warming and moisturizing climate. Another question arises: should we protect and save natural gas for our descendants? For the correct answer to this question, it should be noted that scientists stand on the verge of mastering the energy of nuclear synthesis, even more powerful than the energy of the nuclear decay, but not given radioactive waste, and therefore, in principle, more acceptable. According to American magazines, this will happen in the early years of the Coming Millennium.
Probably, they are mistaken relative to such short terms. Nevertheless, the possibility of such an alternative environmentally friendly energy in the near future is obvious that it is impossible not to be borne in mind when developing a long-term concept for the development of the gas industry.
Methods and methods of ecological and hydrogeological and hydrological studies of natural-technogenic systems in areas of gas and gas condensate deposits.
In ecological and hydrogeological and hydrological studies, it is urgent to address the search for effective and economical methods for studying the state and forecasting man-made processes in order to: develop a strategic concept of production management, ensuring the normal state of ecosystems to develop tactics to solve the complex of engineering problems that promote the rational use of resources of deposits; Implementation of flexible and effective environmental policy.
Ecological and hydrogeological and hydrological studies are based on monitoring data developed by now from the main principal positions. However, the task of constant monitoring optimization is preserved. The most vulnerable part of the monitoring is its analytic and instrumental base. In this connection, it is necessary: \u200b\u200bthe unification of methods for analyzing and modern laboratory equipment, which would allow economically, quickly, with great accuracy to perform analytical work; Creating a single document for the gas branch regulating the entire complex of analytical work.
Methodological techniques of ecological and hydrogeological and hydrological studies in the areas of activity of the gas industry in the overwhelming part are general, which is determined by the uniformity of the sources of technological impact, the composition of the components experiencing technological impact, 4 indicators of technogenic impact.
The features of the natural conditions of the territories of deposits, for example, landscape-climatic (arid, humid and others, shelf, continent, etc.) are due to differences in character, and in the unity of nature, to the degree of intensity of the technogenic influence of the gas industry objects on natural environments . Thus, in fresh groundwater of humiding areas, the concentration of pollutants coming down with the promotions often increases. In arid areas, due to the dilution of mineralized (characteristic of these areas), the concentration of pollutants in them is reduced by fresh or weak and wee-mineralized industrial industries.
Special attention to underground water, when consideration of environmental problems, flows from the concept of groundwater as a geological body, namely underground water - a natural system characterizing the unity and interdependence of the chemical and dynamic properties determined by the geochemical and structural features of underground water containing (breed) and the surrounding ( Atmosphere, biosphere, etc.) media.
From here the multi-faceted complexity of ecological and hydrogeological studies, which consists in simultaneously studying the technogenic effect on groundwater, the atmosphere, surface hydrosphere, a lithosphere (aeration zone breeds and water-receiving rocks), soil, biosphere, in the determination of hydrogeochemical, hydrogeodynamic and thermodynamic indicators of man-made changes, in studying Mineral organic and organic components of the hydrosphere and lithosphere, in the use of inventory and experimental methods.
Studies are subject to both ground (mining, processing and related objects) and underground (deposits, operational and injection wells) sources of technological impact.
Ecological and hydrogeological and hydrological studies make it possible to detect and evaluate almost all possible technogenic changes in natural and natural and technogenic environments in the territories of the enterprise of the gas industry. To do this, there is a major knowledge base about the geological and hydrogeological and landscape-climatic conditions that have developed in these territories, and the theoretical substantiation of the spread of man-made processes.
Any technogenic environmental impact is estimated to compare it with the background of the medium. Natural, natural and man-made, man-made background should be distinguished. The natural background for any indicator under consideration is represented by the value (values) formed in natural conditions, natural-technogenic - in 5 conditions experiencing (test) technogenic loads on the part of the strangers, not monitored in this particular case, technogenic - in the influence of The parties monitored (studied) in this particular case of a technogenic object. Technogenic background is used for a comparative spatial-time estimate of changes in the steppe of the technogenic effect on the medium during periods of operation of the object being tracked. This is a mandatory part of monitoring that ensures flexibility in managing technogenic processes and timely conducting environmental activities.
With the help of natural and natural-technogenic background, the anomalous state of the media under study is found and areas are established, characterized by different intensity. Anomalous state is recorded to exceed the actual (measured) values \u200b\u200band the indicator under study above its background values \u200b\u200b(spafing\u003e ton).
The technogenic object that causes the occurrence of man-made anomalies is established by comparing the actual values \u200b\u200bof the studied indicator with the values \u200b\u200bin the sources of man-made influence belonging to the tracked object.
2. Environmentalnatural Gas Benefits
There are issues related to the environment that prompted numerous research and discussions on an international scale: issues of population growth, preservation of resources, varieties of biological species, climate change. The last question is the most direct attitude to the energy sector of the 90s.
The need for a detailed study and formation of policies internationally led to the creation of an intergovernmental group of climate change professionals (MGIK) and the conclusion of the Climate Change Framework Convention (UNFCC) on the UN. Currently, the UNFCCC is ratified by more than 130 countries joined the Convention. The first conference of the parties (Kos-1) was held in Berlin in 1995, and the second (KOR-2) - in Geneva in 1996, the report of the MGIK was approved on Kos-2, which argued that there were already real evidence of The fact that human activity is responsible for climate change and the effect of "global warming".
Although there is an opinion that opposing the opinion of the MGIK, for example, the European Forum "Science and Environment", but the work of the MGIK at 6 is currently adopted as a reputable basis for the creators of politics, and it is unlikely that the impetus made by the UNFCCC will not encourage further development . Gases. having the most important, i.e. Those concentrations of which have increased significantly from the beginning of industrial activity, is carbon dioxide (CO2), methane (CH4) and nitrogen oxide (N2O). In addition, although the levels of them in the atmosphere are still low, the continuing growth of perfluorocarbon concentrations, and sulfur hexafluoride leads to the need to touch them. All these gases should be included in the national inventories represented by the RCC.
The effect of increasing gas concentrations caused by a greenhouse effect in the atmosphere has been modeled by MGIK on various scenarios. These model studies have shown systematic global climate change, starting from the XIX century. MGIK expects. Between 1990 and 2100, the average air temperature on the earth's surface will increase by 1.0-3.5 C. And the sea level will rise by 15-95 cm. In some places, more severe droughts and (or) floods are expected, at that time How they will be less severe in other places. It is expected that the forests will die that even more will change the absorption and freeing of carbon on land.
The expected temperature change will be too rapid so that individual types of animals and plants have time to adapt. And there is a decrease in the diversity of biological species.
Sources of carbon dioxide can be quantified with sufficient confidence. One of the most significant sources of growth of CO2 concentration in the atmosphere is the combustion of fossil fuels.
Natural gas produces less CO2 per unit of energy. supplied to the consumer. than other types of fossil fuels. Compared to these, the sources of methane are harder to express quantitatively.
On a global scale, according to estimates, sources associated with fossil fuels give about 27% of annual anthropogenic emissions to the atmosphere (19% of total emissions, anthropogenic and natural). Intervals of uncertainty in cases of these other sources are very large. For example. Emissions from garbage dumps are currently estimated at 10% of anthropogenic emissions, but they can be twice as high.
The global gas industry for many years studied the development of scientific ideas about climate change and related policies, and participated in discussions with well-known scientists working in this area. The International Gas Union, Eurogaz, National Organizations and individual companies participated in the collection of data and information related to this issue and thereby contributed to these discussions. And although there are still many uncertainties with respect to the exact estimate of the possible impact in the future gases that create a greenhouse effect, it is appropriate to apply the precautionary principle and ensure that economic efficient emission reduction activities have been carried out as soon as possible. Thus, the compilation of emission inventories and discussion regarding the technology of their decrease helped focus on the most appropriate measures to control and reduce gas emissions creating a greenhouse effect, in accordance with UNFCCC. The transition to industrial fuels with a lower carbon yield, such as natural gas, can reduce gas emissions creating a greenhouse effect, with sufficiently high economic efficiency, and such transitions are carried out in many regions.
The study of natural gas Instead of other types of fossil fuels, it is economically attractive and can make an important contribution to fulfilling the obligations adopted by individual countries in accordance with UNFCCC. This is a fuel that has a minimal environmental impact compared with other types of fossil fuels. The transition from fossil coal to natural gas while maintaining the same ratio of the efficiency of fuel energy conversion into electricity would reduce emissions by 40%. In 1994
The International MGS Environment Commission in the report at the World Gas Conference (1994) turned to studying the issue of climate change and showed that natural gas can make a significant contribution to a decrease in gas emissions creating a greenhouse effect and energy-related energy supply and energy consumption, Providing the same level of convenience, technical indicators and reliability, which will be required of energy supply in the future. EUROGAZ Brochure "Natural gas - cleaner energy for more clean Europe" demonstrates benefits from the use of natural gas, from the point of view of environmental protection, when considering issues from local up to 8 global levels.
Although natural gas has advantages, it is still very important to optimize its use. The gas industry supported the program improvement efficiency programs, supplemented by the development of environmental management, which even more strengthened the arguments in favor of gas from the standpoint of environmental protection as an effective fuel contributing to environmental protection in the future.
Carbon dioxide emissions around the world respond about 65% warming on the globe. The combined fossil fuel exempts CO2, accumulated by plants many millions of years ago, and increases its concentration in the atmosphere above the natural level.
The combustion of fossil fuels causes 75-90% of all anthropogenic carbon dioxide emissions. Based on the most recent data provided by the MGIK, the relative contribution of anthropogenic emissions to the enhancement of the greenhouse effect is estimated by the data.
Natural gas generates less CO2 with the same amount of energy generated to supply than coal or oil, since it contains more hydrogen with respect to carbon than other types of fuel. Due to its chemical structure, gas produces 40% less carbon dioxide than anthracite.
Emissions into the atmosphere when burning fossil fuels depend not only on the type of fuel, but how efficiently it is used. Gaseous fuel is usually burned easier and more efficient than coal or oil. The utilization of waste heat from exhaust gases in the case of natural gas is also simpler, since the furnace gas is not contaminated with solid particles or aggressive sulfur compounds. Thanks to the chemical composition, simplicity and efficiency of use, natural gas can make a significant contribution to a decrease in carbon dioxide emissions by replacing fossil fuels.
3. Water heater WSV-23-1-3-P
gas device thermal water supply
A gas device using thermal energy obtained by burning gas to heate the flowing water for hot water supply.
Decoding of the flow water heater of the WSA 23-1-3-P: WSV-23 B-water heater P - flowing G - gas 23 - heat power 23000 kcal / h. At the beginning of the 70s, the domestic industry has mastered the production of unified water heating flow of household apparatus, which received the HPV index. Currently, water heaters of this series are produced by plants of gas equipment located in St. Petersburg, Volgograd and Lviv. These are apparatus related to automatic devices and are designed to heal water for the needs of local residential supply of the population and utility consumers of hot water. Water heaters are adapted for successful operation in conditions of simultaneous multipoint water intake.
In the design of the flow water heater, WSV-23-1-3-P, a number of significant changes and additions were made compared with the previously produced Water heater L-3, which allowed, on the one hand, to improve the reliability of the apparatus and ensure the increase in the safety level of its work, in In particular, to solve the issue of turning off the supply of gas to the main burner in the violations of the thrust in the chimney, etc. But, on the other hand, led to a decrease in the reliability of the water heater as a whole and the complication of the process of its service.
The water heater housing purchased a rectangular, not very elegant form. The construction of the heat exchanger is improved, the main burner of the water heater is changed by a radical 11, respectively - the insertion.
A new element has been introduced, earlier in flow water heaters not used - electromagnetic valve (EMK); A thrust sensor is installed under the gas supply device (cap).
As the most common means for the rapid production of hot water in the presence of water supply, many years are used by gas flowable water intake vehicles, equipped with gas feeding devices and burden, which, in the case of a short time, the thrust prevent the flame of the gas grinding device, for joining the smoke channel there are smoke-out nozzle.
Device apparatus
1. A wall type apparatus has a rectangular shape formed by removable facing.
2. All the main elements are mounted on the frame.
3. On the front of the device there is a gas crane control knob, an electromagnetic valve button (EMK), an observation window, a window for ignition and monitor the flames of the ignition and the main burner and the thrust control window.
· At the top of the device there is a nozzle of the burning of combustion products into the chimney. At the bottom - nozzles for connecting the apparatus to gas and water highways: for gas supply; For the supply of cold water; For removal of hot water.
4. The device consists of a combustion chamber, which includes a frame, a gas feeding device, a heat exchanger, a water-gasorel block consisting of two burners of the fiber and main, tee, gas crane, 12 water regulator, solenoid valve (EMK).
On the left side of the gas part of the water-gas-melting unit, the tee is fastened with a clamping nut, through which the gas enters the ignition burner and, in addition, it is supplied through a special connecting tube under the valve of the thrust sensor; That in turn is attached to the body of the apparatus under the gas travelers (cap). The thrust sensor is an elementary structure, consists of a bimetallic plate and fitting, on which two nuts performing the connecting functions are attached, and the upper nut is simultaneously the saddle for a small valve attached in a suspended state by the end of the bimetallic plate.
The minimum required for the normal operation of the device must be 0.2 mm of water. Art. If the thrust fell below the specified limit, exhaust combustion products, do not have the ability to fully go into the atmosphere through the chimney, begin to enter the kitchen, heating the bimetallic plate of the thrust sensor, located in a narrow passage on their way out from under the cap. The heating bimetallic plate is gradually strung out, since the linear expansion coefficient when the bottom layer of the metal is greater than that of the top, the free end is lifted, the valve departs from the saddle, which entails the depressurization of the tube connecting the tee and the thrust sensor. Due to the fact that the supply of gas to the tee is limited to the area of \u200b\u200bthe passage section in the gas part of the water-gasorette block, which significantly occupies less than the area of \u200b\u200bthe traction sensor valve, the gas pressure in it immediately drops. Flame of the stobnant without receiving sufficient food, falls. Cooling Saving Thermocouples entails a maximum after 60 seconds. Triggering the solenoid valve. Electromagnet, remaining without electric power supply, loses its magnetic properties and release the anchor of the upper valve, without having the strength to keep it in the position attracted to the core. Under the influence of the springs, the plate, equipped with a rubber seal, fits tightly to the saddle, overlapping through the through passage for the gas, previously entering the main and the ostar burner.
Rules for using a flow water heater.
1) Before turning on the water heater, make sure that there is no smell of gas, open the window and release the cut at the bottom of the door to the air inflow.
2) Flame of burning matches check in chimneyIf you have traction, turn on the column according to the instruction manual.
3) 3-5 minutes after the instrument is turned on re-check the presence of thrust.
4) Do not allow Use the water heater to children under 14 years and persons who have not passed a special briefing.
Use gas water heaters only if there is a thrust in the chimney and the ventilation channel, the rules for storing flow water heaters. Filling gas water heaters should be stored in a closed room protected against atmospheric and other harmful effects.
When storing the apparatus for more than 12 months, the latter must be subjected to conservation.
Holes of the input and outlet nozzles must be closed with plugs or traffic jams.
After every 6 months of storage, the device must be subject to technical inspection.
Operation of the device
• Turning on the device 14 To turn on the device, you must: check the presence of thrust, bringing a lit match or strip of paper to the thrust control window; Open a common crane on the gas pipeline in front of the device; Open a tap on a water pipe in front of the device; Rotate clockwise the handle of the gas crane until you stop; Press the solenoid valve button and bring a lit match through the viewing window in the veneer of the device. At the same time, the flame of the ignition burner should light up; Release the button of the electromagnetic valve, after turning it on to work (after 10-60 seconds), while the flame of the ignition burner should not go out; Open the gas valve on the main burner, for what to press the gas crane handle in the axial direction and turn it right until it stops.
b with this, the ignition burner continues to burn, but the main thing is not yet ignited; Open the hot water valve, the flame of the main burner should be blocked. Adjusting the heating degree of water is performed by water consumption, or by turning the gaseous crane handle from left to right from 1 to 3 division.
i turn off the device. At the end of using the flow water heater, it must be turned off, following the sequence of operations: Close hot water cranes; Turn the handle of the gas crane counterclockwise until it stops, thereby connecting the gas supply to the main burner, then let go of the handle and without pressing it in the axial direction, turn it counterclockwise until it stops. At the same time, the ignition burner and solenoid valve (EMK) will be turned off; Close the overall crane on the gas pipeline; Close the valve on the plumbing pipe.
b water heater consists of the following parts: Camera combustion; Heat exchanger; Framework; Gas feeding device; Gas melting unit; Main burner; Ignition; Tee; Gas crane; Water regulator; Electromagnetic valve (EMK); Thermocouple; Truck Sensor Tube.
Solenoid valve
In theory, the electromagnetic valve (EMK) should stop supplying the gas to the main burner of the flow water heater: first, when the gas supply is disappeared into the apartment (on the water heater), in order to avoid the bodies of the fire chamber, connecting pipes and chimneys, and secondly, In case of violation of thrust in chimney (reduce it against the established norm), in order to prevent carbon monoxide poisoning contained in the combustion products, residents of the apartment. The first of the mentioned functions in the design of previous models of flow water heaters was imposed on the so-called heat machines, the basis of which was bimetallic plates and valves suspended to them. The design was quite simple and cheap. After a certain time, it was out of order after a year or two and no locksmith or the manufacturer did not even arise the thoughts of the time of time and material to restore. Moreover, experienced and knowledgeable insights at the time of the start of the water heater and the primary testing or the most 16 later at the first visit (preventive maintenance) of the apartment in the full consciousness of their rightness were pressed by the folding packets of the bimetallic plate, thereby ensuring the constant open position for the heat machine valve, and Also a 100% guarantee that the specified element of the security automation will not be disturbed until the end of the expiration date of the water heater nor subscribers nor the service personnel.
However, in the new model of the flow water heater, namely Vig-23-1-3-P, the idea of \u200b\u200bthe "heat machine" was developed and complicated significantly, and that the worst, connected with the thrust control machine, laying on the electromagnetic valve The functions that are certainly necessary, but so far have not received a worthy embodiment in a particular viable design. The hybrid turned out to be not very successful, in the work of a capricious, requiring increased attention from the service personnel, high qualifications and many other circumstances.
The heat exchanger, or the radiator, as it is sometimes called in the practice of gas farms, consists of two main parts: a fire chamber and a carrier.
The fire chamber is designed for burning a gas-air mixture, almost entirely prepared in the burner; Secondary air, providing full combustion of the mixture, is suitable from below, between the burner sections. Cold water pipeline (serpentor) wraps a fire chamber with one full turn and gets immediately in the calorifer. The dimensions of the heat exchanger, mm: height - 225, width - 270 (taking into account the protruding knees) and the depth - 176. The diameter of the coating tube 16 is 18 mm, in the above depth parameter (176 mm) it is not enabled. The heat exchanger is single-row, has four through the revolving passages of the water supply tube and about 60 plates-ryber made of copper sheet and having a wave-like shape of the side profile. To install and 17 centering inside the water heater housing, the heat exchanger has side and rear brackets. The main type of solder, at which the knee assembly of the PFPC-7-3-2 knead is carried out. The replacement of solder on the MF-1 alloy is allowed.
In the process of testing the tightness of the inner water plane, the heat exchanger must withstand the pressure test of 9 kgf / cm 2 for 2 minutes (the flows of water from it is not allowed) or to test the air to the pressure of 1.5 kgf / cm 2, subject to immersion in the bath, filled Water, also within 2 minutes, and the air leakage (the appearance of bubbles in water) is not allowed. The elimination of defects of the heat exchanger of the heat exchanger is not allowed. The cold water serpent is almost all over the entire path to the caloric. It should be taken to the fire chamber by the solder to ensure maximum water heating efficiency. At the outlet of the carrier, the exhaust gases fall into the gas feeding device (cap) of the water heater, where the air is diluted, suitable from the room, to the required temperature and then go into chimney through the connecting pipe, the external diameter of which should be about 138-140 mm. The temperature of the exhaust gases at the outlet of the gas feed device is approximately 210 0 s; The content of carbon monoxide with air flow rate 1 should not exceed 0.1%.
Principle of operation of the device1. The gas on the tube enters the solenoid valve (EMK), the inclusion button is located to the right of the handle of the gas crane.
2. The gas locking valve of the water gas-melting unit performs a sequence of switching on the ignition burner, the supply of gas to the main burner and regulates the amount of incoming gas to the main burner to obtain the desired temperature of the heated water.
On the gas crane there is a handle rotating from left to right with fixation in three positions: the extreme left fixed position corresponds to the closing 18 of the gas supply to the ostar and main burner.
The average fixed position corresponds to the full opening of the crane for gas supply to the ignition burner and the closed position of the crane on the main burner.
The extreme right fixed position achieved by pressure on the handle is mainly directed until it stops, followed by turning to the end to the right, corresponds to the full opening of the crane for the gas supply to the main and the ostar burner.
3. The control of the combustion of the main burner is carried out by turning the handle within the position 2-3. In addition to manual locking of the crane, there are two automatic blocking devices. Blocking gas flow to the main burner with the mandatory operation of the ignition burner is provided by an electromagnetic valve operating from the thermocouple.
Locking gas supply to the burner depending on the presence of water duct through the device is made by the water regulator.
When you press the electromagnetic valve button (EMK) and the open position of the blocking gas tap on the ignition burner, gas through the solenoid valve enters the locking valve and then through a tee on the gas pipeline to the ignition burner.
With a normal pull in the chimney (permafection of at least 1.96 Pa), the thermocouple heated by the flame of the ignition burner transmits the pulse to the valve electromagnet, which in turn automatically holds the valve open and provides gas access to the locking crane.
In case of violation of thrust or its absence, the solenoid valve stops supplying the gas to the machine.
The rules for the installation of a flow gas water heater flowing water heater is established in a one-story room in compliance with technical conditions. The height of the room must be at least 2 m. The volume of the room should be at least 7.5 m3 (if in a separate room). If the water heater is installed in the room together with a 19gham plate, then the volume of the room to install the water heater to the room with the gas stove is unnecessary. In the room where the flowing water heater is set, should be chimney, ventkanal, gap? 0.2 m 2 From the door area, windows with a revealing device, the distance from the wall should be 2 cm for the air layer, the water heater should hang on the wall of the non-burnable material. In the absence of non-burnable walls in the room, it is allowed to install a water heater on an employed wall at a distance of at least 3 cm from the wall. The surface of the wall in this case should be isolated roofing steel on the asbestos sheet with a thickness of 3 mm. The upholstery should be for 10 cm for the water heater body. When installing a water heater on a wall, lined with glazed tiles, no additional isolation is required. The horizontal distance in the light between the protruding parts of the water heater should be at least 10 cm. The room temperature in which the device is installed, should be no lower than 5 0 C. Indoors should be natural lighting.
It is forbidden to install a gas flowing water heater in residential buildings above five floors, in the basement and bathroom.
As a complex household appliance, the column has a set of automatic mechanisms that ensure the safety of operation. Unfortunately, many old models installed in apartments today contain a far from a complete set of security automation. And in a large part, these mechanisms have long failed and have been disabled.
Using columns without security automation, or with automatic disabled, is fraught with a serious threat to the safety of your health and property! Safety systems include. Control of reverse traction. If the chimney is blocked either clogged and combustion products come back to the room, the gas supply must automatically stop. Otherwise, the room will be filled with carbon monoxide.
1) Thermoelectric fuse (thermocouple). If a short-term cessation of gas supply occurred during the operating column (ie, the burner was extinct), and then the feed resumed (went gas with an extinct burner), then its further receipt should be automatically stopped. Otherwise, the room will be filled with gas.
Principle of operation of the water-gas blocking system
The blocking system provides gas supply to the main burner only when the hot water isolate. It consists of a water node and gas nodes.
The water assembly consists of a housing, covers, membranes, plates with stock and venturi fitting. The membrane separates the inner cavity of the water node to the subable and apprailed, which are connected by the bypass channel.
When the water intake is closed, the pressure in both cavities is the same and the membrane occupies the lower position. When opening the water intake, the water flowing through the "Venturi" fitting is injected through the bypass canal water from the above-handed cavity and the water pressure drops in it. The membrane and a plate with a rod rise, the water node rod pushes the gas rod, which opens the gas valve and gas enters the burner. With the cessation of water intake of water pressure in both cavities of the water assembly, the gas valve is alleged under the influence of the conical spring and stops gas access to the main burner.
The principle of operation of automatics to control the presence of a flame on the stall.
Provided by the work of EMK and thermocouples. When weakening or extracting the flame, the spike thermocouple is not heated, the EMF is not thrown away, the electromagnet core is demagned and the spring's spring is closed, overlapping the gas supply to the machine.
Principle of operation of automatics of safety by traction.
§ Automatic shutdown of the device in the absence of thrust in the chimney is provided: 21 thrust sensors (DT) EMK with a thermocouple fiber.
Dt consists of a bracket with a bimetallic plate fixed on it. At the free end of the plate, the valve closes the hole in the sensor fitting is fixed. The DT fitting is attached to the bracket with two lock nuts, with the help of which you can adjust the height of the plane of the outlet of the fitting relative to the bracket, thereby adjusting the valve closing density.
In the absence of thrust in chimney, the flue gases go out under the cap and heated the bimetallic plate of DT, which bends, raises the valve, opening the hole in the fitting. The main part of the gas, which should go to the spinner, goes through the hole in the sensor fitting. The flame on the stall decreases or goes out, heating the thermocouple stops. EMF in the winding of the electromagnet disappears and the valve overlaps the gas supply to the machine. The response time of the automation should not exceed 60 seconds.
WSV-23 safety automation scheme Scheme of automatic safety water heaters with automatic shutdown of gas supply to the main burner in the absence of traction. This automation works on the basis of the EMK-11-15 solenoid valve. The thrust sensor serves a bimetallic plate with a valve that is installed by the water heater area. In the absence of traction, hot combustion products are washed the plate, and it opens the nozzle of the sensor. In this case, the flame of the ignition burner decreases, since the gas rushes the sensor's nozzle. The thermocouple of the EMK-11-15 valve cooles and it overlaps gas access to the burner. The solenoid valve is embedded on gas in front of the gas valve. EMK power supply ensures a chromel-copy thermocouple introduced into the flame zone of the ignition burner. When heating the thermocouple, the excited TADS (up to 25mB) enters the electromagnet core winding, which holds the valve associated with an anchor. The valve opening is manually carried out using the button displayed on the front wall of the device. When popping flames, the unworn 22 electromagnet spring-loaded valve overlaps gas access to burners. Unlike other electromagnetic valves, in the EMK-11-15 valve, thanks to the sequential response of the lower and top valves, it is impossible to turn off the safety automation by consolidating the lever pressed from the work, how the consumers do it. As long as the lower valve does not block the gas pass to the main burner, the flow of gas into the ignition burner is impossible.
For blocking thrust, the same EMK and the effect of the replacement burner are used. The bimetallic sensor placed under the top cap of the device is heating, (in the zone of the reverse flux of hot gases arising from stopping the thrust) opens the gas reset valve from the piping of the ignition burner. The burner goes out, the thermocouple is cooled and the electromagnetic valve (EMK) overlaps gas access to the machine.
Maintenance of the apparatus 1. Observation of the work of the device is assigned to the owner, which is obliged to contain it clean and good condition.
2. To ensure the normal operation of the flow gas water heater at least once a year, a preventive inspection must be carried out.
3. Periodic maintenance of the flow gas water heater is made by employees of the gas management service in accordance with the requirements of operating rules in the gas economy at least 1 year per year.

Disaster electric chain
The causes of the chain disorders are quite a lot, they are usually a consequence of the break (violation of contacts and places of compounds) or, on the contrary, the closure before the electric current produced by the thermocouple falls into the electromagnet coil and thereby ensure the steady attraction of the anchor to the core. Chain breaks, as a rule, are observed in the location of the thermocouple and a special screw terminal, in the place of fastening the core winding to figure or connecting nuts. The circuit of the chain is possible in the thermocouple itself due to the negligent appeal (fractures, bends, blows, etc.) in the service process or due to the failure as a result of an excessive service life. It is often possible to observe in those apartments where the water heater's watelling burner burns all day, and often a day, to avoid the need to ignite it before turning on the water heater to work, which the hostess may be more than a dozen. Circuits of the chain are possible in the electromagnation itself, especially when displaced or disruption of the insulation of a special screw made of washers, tubes and similar insulating materials. Natural will be in order to accelerate the repair work to each occupied on their implementation, have constantly spare thermocouple and electromagnet with them.
The locksmith in search of the cause of the valve failure should first get a clear answer to the question. Who is to blame for the valve failure - thermocouple or magnet? The first is replaced by the thermocouple as the easiest option (and the most common). Then, with a negative result, the same operation is exposed to an electromagnet. If it does not help, then the thermocouple and electromagnet are extracted from the water heater and are checked separately, for example, the spay thermocouple is heated by the flame of the top burner of the gas stove in the kitchen and so on. Thus, the mechanic method of exclusion establishes a defective node, and then it is starting directly to repair or simply replacing it to a new one. Determine the reason for the refusal of the electromagnetic valve in the work, without resorting to a phased study, by replacement, the intended defective nodes on the obviously good, only an experienced, qualified mechanic can only.
