Description
Technical field
The present invention relates to a kind of water heater method for extinguishing fire and tap that prevents the water heater fire extinguishing of preventing.
Background technology
At present, water heater is used in China widely.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 instant electric water heater and quick-heating electric water heater again.Early stage water heater is non-thermostatic type water heater mostly; 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 through the user, until the suitable current of output temperature.
Existing combustion taps comprises the cold and hot water yield adjusting mixing valve assembly that is provided with the valve regulated handle; The two ends that the cold and hot water yield is regulated mixing valve assembly inner spool are respectively through the water inlet sealing gasket into water sealed joint pipe bolt that is tightly connected; The other end of water inlet sealed joint pipe bolt is plugged in the loose joint nut; And, also are furnished with two trims on the loose joint nut through loose joint sealing gasket be tightly connected cold water pipe and hot-water line.Existing combustion taps cold water water inlet sealed joint pipe bolt is consistent with the nominal caliber size of hot water water inlet sealed joint pipe bolt; Be 10mm; And major part all has only a spool; The import of spool two ends is connected cold water pipe and the hot-water line (combustion taps that a spot of two spools are also arranged through 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, have only cold water control valve and hot water control valve, the combined amount that the user can regulate hot and cold water through cold water control valve and hot water control valve.This combustion taps also is to connect control valve valve body and water inlet pipe through 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 caliber size; And the resistance of heating tube is big; 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 gas heater heating tube 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 portion of hot hydrophone is arranged when opening hot water separately; When hot water flow during less than a certain limiting value; Water temperature in the gas heater heating tube can reach the limiting temperature of water heater, and 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 gas heater heating tube 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, also the phenomenon that electric heater stops to heat can appear, and reason is identical with the non-thermostatic type gas heater of use, repeats no more at this.
Therefore, existing non-thermostatic type gas heater and non-thermostatic type instant electric water heater can fire extinguishing occur or stop heating phenomena when cooperating existing combustion taps to use under multiple situation, use very inconvenience.
At present, a large amount of thermostatic type gas heaters has appearred also on the market, the temperature output hot water that water heater can directly be set according to the user; Can separate the fire extinguishing of thermostatic type water heater appearance by no means or stop heating phenomena; But its internal structure is complicated, and the probability that breaks down is high, and costs an arm and a leg.Instruct method for using by producer, the thermostatic type water heater need not mixing hot and cold water in use.But in actual use, owing to change combustion gas gas kind, also can occur because of the too high phenomenon that can't use of water temperature, the user must reduce water temperature by mixing hot and cold water.In mixing hot and cold water process, the thermostatic type water heater fire extinguishing also can occur or stop heating phenomena, and reason is identical with the non-thermostatic type water heater of use, repeats no more at this.
