Description
Technical field
The present invention relates to the technical field of daily necessities, particularly relate to a kind of technology of water tap control valve of the water-saving instant-heating water heating system that is used for zero-emission.
Background technique
There is such problem usually in existing domestic hot water system, when bringing into use hot water, need could use hot water after emitting that part of water that does not reach temperature requirement.When particularly having a bath, people often wait until to enter after the complete heat of water again and have a bath.The not high enough water of so a lot of temperature can slattern.Along with the increase of living space and increasing of toilet, the pipeline that connects between water heater and the hot water tap is also more and more longer, and is also just more and more by the water of unnecessary waste.Therefore, people wish and can take measures, and the water conservancy of this part unnecessary waste is used.
In the patent No. is 03231013.7, and name is called in the Chinese utility model patent of water heater, has proposed a kind of zero-emission water-heater system water-saving technology scheme that can realize a plurality of hot water use point instant-heating.Promptly below the hot water tap, increase the circulation loop of solenoid valve and cold water, a closure of hot-water line composition, and use a supercharging device that cold water is in earlier stage sent back to and carry out Heating Cyclic in the water heater, and then reach and open tap and can use hot water, need not emit a part of cold water and must resemble before use the prior art, so be referred to as zero-emission.The purpose of water saving; As shown in Figure 1, water heater comprise a water heater body 1, from water heater body's 1 extended cold water pipe 2 and a hot-water line 3 and a heating equipment that is arranged in the water heater body 1.In addition, this water heater is also particularly including cold water pipe 2 and a valve 5 between the hot-water line 3 and the supercharging device 4 by remote controller 7 controls that is arranged in the circulation loop that is formed by cold water pipe 2, hot-water line 3 and valve 5 that is installed in each water tap A, B, C, D.By the effect of supercharging device 4, the water heating equipment that passes through capable of circulation in the circulation loop that cold water pipe 2, hot-water line 3 and valve 5 form.In addition, can be connected the two ends of supercharging device 4 with a pipeline, thereby under the situation that does not activate supercharging device 4, water non-resistance ground be passed through from this root short circuit pipeline as shown in Figure 1, and then satisfy the needs that hot water is used in circulation heating back.And valve 5 wherein both can also can be solenoid valve 5 for manually operated valve 5.Technique scheme can be received good water-saving result.Obtain by actual measurement, when water heater when hot water tap's pipeline distance is 6 meters, the bathing in summer once can be saved 6-7 liter water, winter then can little waste water 13-15 liter.On average get off everyone each bathing 10 liters of can economizing on water.But, described method need install a solenoid valve additional at the hot water tap place, promptly increased the expense of repacking, also exist simultaneously and difficulty, inconvenient maintenance are installed and may produce the hidden danger of leaking, leaking electricity, this has brought insoluble difficulty and problem for the enforcement and the popularization of water-saving type circulation water-heating system.
Summary of the invention
