Description
Technical field the utility model belongs to the water valve technical field, relates to a kind of thermostatic valve.
Background technique is adjusted the water valve that hot and cold water reaches constant temperature water supply at present, is the armstrong's patent adjustment mostly.Because there is certain distance in the hot and cold water mixed zone in water outlet and the valve body, the water outlet water temperature can not directly reflect the temperature of water in the valve body.Can only adjust repeatedly with sensation and just can reach the water temperature that needs, be in course of adjustment and make water cause unnecessary waste: in addition, because hydraulic pressure shakiness in the water utilizing process, the effect of the thermostatic valve constant temperature water supply of prior art will be affected when hydraulic pressure is too high or too low, it is low or too high that the water outlet water temperature is crossed, and influences using effect.
The summary of the invention the technical problems to be solved in the utility model is, water temperature is inconsistent and influence technical problems such as using effect when the hydraulic pressure shakiness in prior art water valve outlet water temperature and the valve body, thereby a kind of adjustable thermostatic valve is provided.
The adjustable thermostatic valve of the utility model, be on the basis of prior art, to improve to realize, it comprises valve body, spool, knob, positioning ring, hot water or cold water's import and thermostatted water outlet, its main points are that its spool is assembled by regulating lever, straight shape spring, push rod, piston, inductor, turriform spring successively from top to bottom, and hot water or cold water's import is respectively equipped with cold water flow-limiting valve and hot water flow-limiting valve.
Said inductor is sleeved in the spring ring on turriform spring top, and the thermoinduction material is housed in the inductor, and the thermoinduction material is provided with the caulking gum diaphragm, and diaphragm is provided with conduction mud, and it is corresponding that conduction mud is provided with the lower end surface of plastic sealing gasket and push rod.
Said flow-limiting valve comprises the flow-limiting valve housing, housing is built-in with the taper valve rod, the valve rod top is provided with the adjustment knob, stem bottom is fixed on the housing by pad, spring pad, nut, it is corresponding with the thermostatic valve water intake that the valve rod middle part is provided with through hole, by adjusting the opening degree of knob adjustment cone stem through-hole, the flow size of regulating water inlet.
Said flow-limiting valve is by being separately fixed on thermostatic valve cooling water inlet, the hot water inlet from the body silk.
Working principle of the present utility model is, with the utility model by in the pipeline of packing into, open hot water or cold water's inlet valve, hot water enters the inductor of flowing through in the valve body by the hot water flow-limiting valve, make the interior thermoinduction material expanded by heating of inductor with push rod jack-up, under the effect of turriform spring and straight shape spring piston is descended, the space of piston and hot water inlet lower bolster diminishes, and the hot water influx reduces gradually.Simultaneously, cooling water inlet is opened, and cold water enters the inductor of flowing through in the valve body, make the shrinkage of suffering from cold of thermoinduction material in the inductor, make turriform spring and straight shape spring compressing inductor and push rod, piston rises, the space of piston and cooling water inlet upper mounting plate diminishes, and the cold water influx reduces gradually.At this moment, piston is located state of equilibrium under the effect of turriform spring and straight shape spring, hot and cold water is mixed in proportion, reaches constant temperature.This is that the interior water temperature of water temperature and the valve body of thermostatted water outlet is consistent; If will improve the water temperature of thermostatted water outlet, rotary knob counterclockwise, it is up to drive regulating lever, piston and inductor along with on move, the space of piston and hot water inlet lower bolster diminishes, and enters cool water quantity and reduces, the water temperature raising that exports of thermostatted water at this moment; If will reduce the water temperature of thermostatted water outlet, button then turns clockwise; When if hydraulic pressure is too high or too low in the pipeline in the using process, can make the water that enters in the valve body be in constant flow rate by adjusting hot water or cold water's flow-limiting valve, thereby the water temperature that guarantees the constant-temperature effluent mouth is constant: in the using process, if tap water is cut off the water supply, hot water constantly flows into, thermoinduction material expanded by heating in the inductor, push rod continues to rise, and piston continues to descend, with piston and hot water inlet lower bolster space closure, the thermal water source promptly is cut off, and hot water stops to supply water; Otherwise when hot water was cut off the water supply, cold water flowed into the shrinkage of suffering from cold of the thermoinduction material make in the inductor, and push rod descends, and piston rises, and with the platform space closure on piston and the cooling water inlet, cold water source promptly is cut off, and cold water stops water supply.
The utility model simple structure, easy to use, water temperature is consistent in water valve outlet water temperature and the valve body, avoided the waste of water in the using process, and the hydraulic pressure shakiness does not influence using effect yet in the using process, after a kind of water source cuts off the water, also has the function at the another kind of water source of automatic cut-out.
