Embodiment
Embodiment:
Consult Fig. 2-6, a kind of constant-temperature water mixing valve, comprise the valve body 1 having and regulate handle 5, backwater end 2, feed-water end 3 and mixing water end (W.E.) 4, valve body 1 is also provided with the second backwater end 6, wherein the second backwater end 6 and backwater end 2, feed-water end 3 and to mix water end (W.E.) 4 in the same plane, regulates handle 5 to be vertically set on valve body 1.
The valve body 1 of constant-temperature water mixing valve is four-way structure, its four ports are in the same plane, connect extraneous hot water, pump entry, water-collecting machine and extraneous backwater respectively, thus save the pipeline and joint that arrange separately for extraneous backwater, decrease pipe fitting consumption and volume, regulate handle to be vertically set on valve body 1 in addition, make full use of height space, further simplify structure, be convenient to installation and maintenance, use and also facilitate.
Be provided with thermometer bulb 7, thermometer bulb push rod 8 in valve body 1, be arranged on the volute spring 9 between thermometer bulb 7 and valve body 1 inwall, the piston 10 be set on thermometer bulb push rod 8, setscrew nut 12, valve rod 14, wherein the outer wall of setscrew nut 12 is connected on valve body 1 by outside thread 13, one end of valve rod 14 extends to and valve body 1 outer also connection regulates handle 5, the other end extends in valve body 1 inner chamber through setscrew nut 12, thermometer bulb push rod 8 is arranged between thermometer bulb 7 and valve rod 14, is provided with overload spring 15 and locating stud 16 between valve rod 14 and thermometer bulb push rod 8 in turn.Valve body 1 inner chamber is separated into two cavitys by piston 10, piston 10 is provided with the through hole 11 of connection two cavitys, feed-water end 3 and mixing water end (W.E.) 4 communicate with valve body 1 inner chamber of thermometer bulb 7 side respectively, and backwater end 2 and the second backwater end 6 communicate with valve body 1 inner chamber of valve rod 14 side respectively.The sidewall of piston 10 is provided with circular groove 17, in circular groove 17, is provided with seal ring 18.
The hot water entered from feed-water end 3 directly enters valve body 1 inner chamber of thermometer bulb 7 side, the backwater that water-collecting machine returns enters from backwater end 2, a part directly exports the external world by the second backwater end 6, another part enters in valve body 1 inner chamber of thermometer bulb 7 side by the through hole 11 of piston 10, and hot water and the mixed mixed water of backwater enter recycle pump by mixed water end (W.E.) 4.By regulating handle 5 to rotate, the distance that valve rod 14 extends in valve body 1 inner chamber can be changed, thus adjust the position of locating stud 16 and thermometer bulb push rod 8 in advance, for regulating the different temperatures of needs.Comprising paraffin in thermometer bulb 7, is solid-state under normal temperature, liquefy when heated, in whole transfer process, the volume of paraffin can expand, because thermometer bulb 7 three is fixed, the paraffin of expansion can promote thermometer bulb push rod 8 and move, thus converts the change of heat the displacement of thermometer bulb push rod 8 to.If water-mixing temperature exceedes default temperature, expansion can be produced after thermometer bulb 7 is heated, promote thermometer bulb push rod 8 to move to valve rod 12 direction, under the reaction force being subject to valve rod 12 restriction generation, promote volute spring 9 to compress, thermometer bulb push rod 8 drives piston 10 to move to valve body 1 inner chamber of thermometer bulb 7 side, thus reduces the circulation area of feed-water end 3, reduce the hot water amount entered, water-mixing temperature is declined; Otherwise when water-mixing temperature is lower than setting value, under the elastic force effect of volute spring 9, thermometer bulb push rod 8 drives piston 10 to move to valve rod 14 side, increases the circulation area of feed-water end 3, enters more hot water, improve the temperature of mixed water.By said structure, the constant adjustment of water temperature can be realized.Overload spring 15 can play the effect that buffering thermometer bulb push rod 8 moves, and prevents from making thermometer bulb 7 overexpansion because entering water temp is too high and causing valve body 1 to damage.
Above-listed detailed description is illustrating for one of the utility model possible embodiments, this embodiment is also not used to limit the scope of the claims of the present utility model, allly do not depart from the equivalence that the utility model does and implement or change, all should be contained in the scope of the claims of this case.
