Embodiment

Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, specific embodiment described herein is only Only to explain the utility model, it is not used to limit the utility model.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of mixed cold and hot water valve with back-water valve (BWV), it includes valve body 1, valve element 2 and hand Handle 3, the valve body 1 are provided with cold water interface 11, interface of hot water 12, delivery port 13, valve element chamber 14, cold water chamber 15, hot-water cavity Room 16 and mixed water chamber 17, the valve element 2 are arranged on valve element chamber 14 and coordinate the flow of control hot water or cold water and mixed water with valve body 1 Ratio, a through hole 4 is provided between the hot water chamber 16 and cold water chamber 15, a check-valves 5 is set in the through hole 4, it is described Check-valves 5 controls current to flow into cold water chamber 15 from hot water chamber 16, the mixed cold and hot water valve and backwater circulation device, water heater Coordinate one backwater channel of lower composition.

When need to take a shower, backwater circulation device starts in a manner of automatic, timing, remote control, manual or water flow sensing unit trigger Pump working, the injection cold water to pressurize to water heater, cold water flow to hot water pipeline to the mixed cold and hot water valve after being heated by water heater, Check-valves 5 in the mixed cold and hot water valve body is opened, and the cold water being stored in hot-water line flows into cold water pipes and forms a return pipe Road, the cold water in hot-water line are replaced with hot water, instant hot water's supply of household are realized, without opening the fire hose in advance as traditional After head or gondola water faucet wait cold water to drain, reusable heat water realizes the effect of plug and play, while does not waste water, and saves the time, carries The comfortableness that high hot water uses.

Techniques discussed above scheme is only preferred embodiments of the present utility model.It should be pointed out that for ability For the those of ordinary skill in domain, in the case where not departing from the utility model principle, some improvement and modification can also be made, This is also considered as in the scope of protection of the utility model.
