Description
Technical field
The utility model relates to a kind of water supply of water heater system, relates in particular to a kind of water supply of water heater system with anti-fire-extinguishing function concurrently.
Background technology
At present, water heater is used widely in China.Water heater mainly is 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 mostly is greatly non-thermostatic type water heater, comprise gas heater, instant electric water heater and quick-heating electric water heater, they all are the hot water of output high-temperature from the hot-water line of water heater, use combustion taps mixing hot and cold water by the user, until the current that output temperature is fit to.
Existing combustion taps comprises the cold and hot water yield adjusting mixing valve assembly that is provided with valve regulating handle, the two ends that the cold and hot water yield is regulated mixing valve assembly inner spool are tightly connected into water sealed joint pipe bolt by the water inlet sealing gasket respectively, the other end of water inlet sealed joint pipe bolt is plugged in the loose joint nut, and by loose joint sealing gasket be tightly connected cold water pipe and hot-water line, also are furnished with two trims on the loose joint nut.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 the hot-water line (combustion taps that two a small amount of spools are also arranged by water inlet sealed joint pipe bolt respectively with the loose joint nut, 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, also is used for adjusting simultaneously hot water or cold water's flow.The minority combustion taps is also arranged, do not have mixed valve core, only have cold water control valve and hot water control valve, the combined amount that the user can regulate hot and cold water by cold water control valve and hot water control valve.This combustion taps also is to connect control valve valve body and water inlet pipe by water inlet sealed joint pipe bolt.
Use in the non-constant temp gas water heater process, when hot and cold water mixed, cold water pipe and hot-water line were communicated with.Because the cold water inlet of existing combustion taps is consistent with hot water inlet pipe's nominal pipe diameter size, 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 has so just caused the hot water flow minimizing much smaller than hot-water line.When the flow of hot water during less than a certain limiting value, the water temperature in the heating tube of gas water heater can rise to the limit value of gas heater.At this moment, the automatic safety device in the gas heater can cut off the supply of combustion gas, makes the gas heater self-extinguishing.
In using non-constant temp gas water heater process, also there is the another one problem; the part water heater is arranged when opening hot water separately; when hot water flow during less than a certain limiting value; water temperature in the 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 the gas heater self-extinguishing.The non-thermostatic type water heater of part is arranged, and when the flow of hot water during greater than a certain limiting value, the water temperature in the heating tube of gas water heater is lower than the temperature that water heater limits, and the self-con-tained unit of water heater also can cut off combustion gas, makes the gas heater self-extinguishing.
When using non-thermostatic type instant electric water heater, the phenomenon of electric heater stopped heating also can appear, and 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 can fire extinguishing or stopped heating phenomenon occur in multiple situation when cooperating existing combustion taps to use, and it is very inconvenient to use.
At present, a large amount of thermostatic gas water heaters has appearred also on the market, the temperature output hot water that water heater can directly be set according to the user, but solution is fire extinguishing or the stopped heating phenomenon of thermostatic type water heater appearance by no means, but its internal structure is complicated, and the probability that breaks down is high, and expensive.Instruct using method by producer, thermostatic type water heater need not mixing hot and cold water in use.But in actual use, owing to change combustion gas gas kind, the phenomenon that can't use because of water temperature over-high also can occur, the user must reduce water temperature by mixing hot and cold water.In mixing hot and cold water process, fire extinguishing or stopped heating phenomenon also can appear in thermostatic type water heater, and reason is identical with the non-thermostatic type water heater of use, does not repeat them here.
