Description
Technical field
The present invention relates to a kind of tap that prevents the method for water heater fire extinguishing and prevent water heater fire extinguishing.
Background technology
At present, water heater is applied widely in China.Water heater is mainly divided into four kinds of electric heater, gas heater, solar water heater and air-source water heaters.Electric heater is divided into again instant electric water heater and quick-heating electric water heater.Early stage water heater is mostly non-thermostatic type water heater, comprise gas heater, instant electric water heater and quick-heating electric water heater, they are all the hot water of exporting high-temperature from the hot-water line of water heater, use combustion taps mixing hot and cold water by user, until the applicable current of output temperature.
Existing combustion taps comprises that the cold and hot water yield that is provided with valve regulating handle regulates mixing valve assembly, the cold and hot water yield regulates the two ends of mixing valve assembly inner spool to be tightly connected into water sealed joint pipe bolt by water inlet sealing gasket respectively, the other end of water inlet sealed joint pipe bolt is plugged in loose joint nut, and by loose joint sealing gasket be tightly connected cold water pipe and hot-water line, on loose joint nut, are also furnished with two trims.Existing combustion taps cold water water inlet sealed joint pipe bolt is consistent with the nominal pipe diameter size of hot water water inlet sealed joint pipe bolt, be 10mm, and major part all only has a spool, the import of spool two ends is connected cold water pipe and hot-water line by water inlet sealed joint pipe bolt respectively with loose joint nut (also have the combustion taps of two a small amount of spools, the tap of its operation principle and a spool is similar), this spool should be used for regulating hot water or cold water's combined amount, is also used for adjusting hot water or cold water's flow simultaneously.Also have minority combustion taps, there is no mixed valve core, only have cold water control valve and hot water control valve, user can regulate by cold water control valve and hot water control valve the combined amount of hot and cold water.This combustion taps is also to connect control valve valve body and water inlet pipe by water inlet sealed joint pipe bolt.
Use in non-constant temp gas water heater process, in the time that hot and cold water mixes, cold water pipe and hot-water line are communicated with.Due to the cold water inlet of existing combustion taps and hot water inlet pipe's nominal pipe diameter size consistent, and the resistance of heating tube is large, increased the drag overall of hot-water line pipeline, and the drag overall of cold water pipe pipeline is much smaller than hot-water line, has so just caused hot water flow minimizing.In the time that the flow of hot water is less than a certain limiting value, the water temperature in heating tube of gas water heater can rise to the limit value of gas heater.Now, the automatic safety device in gas heater can cut off the supply of combustion gas, makes gas heater self-extinguishing.
In the non-constant temp gas water heater process of use, also there is another one problem; there is part water heater in the time opening hot water separately; in the time that hot water flow is less than a certain limiting value; water temperature in heating tube of gas water heater can reach the limiting temperature of water heater; the automatic safety device of gas heater can cut off the supply of combustion gas, makes gas heater self-extinguishing.There is the non-thermostatic type water heater of part, in the time that the flow of hot water is greater than a certain limiting value, the temperature that the water temperature in heating tube of gas water heater limits lower than water heater, the self-con-tained unit of water heater also can cut off combustion gas, makes gas heater self-extinguishing.
In the time using non-thermostatic type instant electric water heater, also there will be electric heater to stop the phenomenon of heating, reason is identical with the non-thermostatic gas water heater of use, does not repeat them here.
Therefore, existing non-thermostatic gas water heater and non-thermostatic type instant electric water heater, in the time coordinating existing combustion taps to use, can occur putting out a fire or stopping heating phenomena in multiple situation, and it is very inconvenient to use.
At present, on market, also there is a large amount of thermostatic gas water heaters, the temperature output hot water that water heater can directly be set according to user, can solution thermostatic type water heater occurs by no means fire extinguishing or stop heating phenomena, but its internal structure complexity, the probability breaking down is high, and expensive.Instruct using method by producer, thermostatic type water heater is in use without mixing hot and cold water.But in actual use, owing to changing combustion gas gas kind, also there will be the phenomenon that cannot use because of water temperature over-high, user must reduce water temperature by mixing hot and cold water.In mixing hot and cold water process, thermostatic type water heater also there will be fire extinguishing or stops heating phenomena, and reason is identical with the non-thermostatic type water heater of use, does not repeat them here.
