Description
Technical field
The utility model relates to a kind of electric water heater, particularly a kind of pressure-balance type thermostatic valve assembly that is applied on the electric water heater.
Background technique
At present, the common safety valve that is applied on the electric water heater adds mixed water valve as shown in Figure 1, comprise and mix water valve 1 ' and safety valve 4 ', be communicated with cold water channel 2 ' and hot water channel 3 ' on the described mixed water valve 1 ', this cold water channel 2 ' water intake is communicated with water supply pipe by connecting head, be positioned at cold water channel 2 ' upper end water outlet and be connected with the water intake of electric heat water tank by safety valve 4 ', the water outlet of described electric heat water tank communicates with hot water channel 3 '; During use, after tap water entered cold water channel 2 ', a part enters into mixed water valve 1 ', and another part enters into electric heat water tank through safety valve 4 ' and heats, heated hot water enters into the hot water channel from the water outlet of electric heat water tank, mixes in the mixed water channel that mixes water valve 1 '; In the using process, in case tap water hydraulic changes suddenly, the water yield that enters into electric heat water tank from safety valve will abrupt change because of the resistance that is subjected to safety valve non-return Returnning spring, cause mixing the mixed proportional imbalance of converting that mixes in the water valve 1 ' in the water channel, make from mixing the water that water valve 1 ' comes out sometimes hot and sometimes cold, use weak effect and very inconvenience,, be necessary to make improvements at above-mentioned shortcoming.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, pressure-balance type thermostatic valve assembly that using effect is good.
The technological scheme that its technical problem that solves the utility model adopts is:
Pressure-balance type thermostatic valve assembly, comprise mixed water valve, safety valve, be communicated with cold water channel and hot water channel on the described mixed water valve, the water intake of described cold water channel is communicated with water supply pipe by safety valve, the upper end-hole of this cold water channel communicates with the water intake of electric heat water tank, the water outlet of described electric heat water tank communicates with the hot water channel, be provided with cold water cavity in the described mixed water valve, hot water cavity, mix water channel, at cold water cavity, be provided with the temperature adjustment spool between the hot water cavity, this temperature adjustment spool can be opened, close cold water cavity or hot water cavity, described mixed water valve is provided with the exhalant canal that communicates with mixed water channel, between mixed water channel and exhalant canal, be provided with the effluent switch valve, water intake and cold water channel that the valve that leaks is arranged, the hot water channel, mixed water channel communicates, and the water outlet of the described valve that leaks communicates with atmosphere.
The beneficial effects of the utility model are: during use, tap water at first enters into cold water channel from safety valve, a part enters in the electric heat water tank through cold water channel, another part enters into and can open, in the cold water cavity of closing, the tap water that enters in the electric heat water tank flows back into and can open from the hot water channel through high temperature heating back, in the hot water cavity of closing, simultaneously cold, water in the hot water cavity has also entered mixed water channel, in mixing water channel, mix, flow out from the effluent switch valve at last, in this process, utilize temperature adjustment spool may command cold, tap water in the hot water cavity enters mixed water channel, heat to mixing water is adjusted, the effluent switch valve then is that the size of water-outlet quantity is adjusted, owing to adopted said structure, tap water is at first proceeded in the cold water channel from safety valve, solved the water non-resistance that enters in the electric heat water tank, in use, even the hydraulic pressure of tap water changes, also just have influence on the Total Water that enters cold water channel, and can not change the water yield ratio that enters in cold water cavity and the electric heat water tank, make the hot water in the hybrid channel and the ratio of cold water remain constant, guaranteed that also from the water temperature that the effluent switch valve comes out be constant all the time, improved the stability and the using effect of product effectively.
