Abstract
The utility model relates to a device, in particular to a self-supporting thermostatic mixed water valve which is capable of mixing the cold water and the hot water to be the required temperature automatically according to the preset temperature. The self-supporting thermostatic mixed water valve consists of a hot water inlet, a cold water inlet, a thermometer bulb protective component, an adjusting handle and an offsetting spring component. The backs of the hot water inlet and the cold water inlet are respectively provided with an equipressure chamber, and the water entered into the equipressure chamber generates the same pressure to the valve plug component and a valve plug sealing gasket, so that when the water pressure is increased or decreased, the water pressure generates the same increased or decreased pressure to the valve plug component and the valve plug sealing gasket simultaneously under the effect of the equipressure chamber, thus ensuring the temperature of the yielding water will not be influenced by the increase or the decrease of the water pressure; in addition, a pressure guide hole is additionally arranged between the equipressure chamber of the hot water inlet and the equipressure chamber of the cold water inlet, so that the equipressure chamber of the hot water inlet and the equipressure chamber of the cold water inlet are under the same water pressure, the up and down movement of the valve plug becomes easier, the thrust of the thermometer bulb is decreased and the self-supporting thermostatic mixed water valve is capable of working more reliably.
Description
Affiliated technical field
The utility model relates to a kind of device that cold water and hot water is mixed into needed temperature, especially can automatically cold water and hot water be mixed into a kind of self-supporting thermostatic water mixing valve of needed temperature according to predefined temperature, belong to hot-water supply system's manufacturing field of equipment.
Background technique
At present, various hot-water supply systems are quite universal, the application of various hot-water supply system's equipment also is found everywhere, but, the hot water temperature that problem demanding prompt solution of ubiquity is supplied with when fluctuation takes place hydraulic pressure in present hot-water supply system also changes, can't the guarantee supply constant-temperature effluent of hot water descends the quality of hot water supply.In addition, if cold water has taken place suddenly in present hot-water supply system to open circuit, can't cut off the supply of hot water immediately, the hot water temperature of supply is raise, injure user's safety, in order to address the above problem, many constant-temperature water mixing valves have appearred on market at present, but all can't solve the variation of the water-exit temperature that water pressure fluctuations brings, the utility model provides a kind of self-supporting thermostatic water mixing valve that hot water temperature that power supply just can guarantee to supply with does not also change that need not when fluctuation takes place hydraulic pressure, when the supply of unexpected interruption cold water, self-supporting thermostatic water mixing valve can cut off the supply of hot water immediately.
Summary of the invention
The purpose of this utility model is: a kind of self-supporting thermostatic water mixing valve that does not need power supply can according to predefined temperature cold water and hot water be mixed into predefined temperature automatically is provided, when the supply of unexpected interruption cold water, self-supporting thermostatic water mixing valve can cut off the supply of hot water immediately, guarantees user's safety.
Solving the technological scheme that its technical problem adopts is that self-supporting thermostatic water mixing valve is by the hot water inlet; cold water inlet; thermometer bulb protection assembly; regulating handle; Returnning spring is formed; it is characterized in that: an isobaric cavity is respectively arranged at hot water water inlet and cold water water inlet back; make the water that enters into isobaric cavity produce identical pressure with the seal spool pad to mangetic core assembly; the pressure that when hydraulic pressure increases or reduces, makes hydraulic pressure produce identical increase or reduce mangetic core assembly and seal spool pad simultaneously under the effect at isobaric cavity like this; thereby the temperature that has guaranteed water outlet is not subjected to the influence that increases or reduce because of hydraulic pressure; in addition; the centre of going into isobaric cavity at the isobaric cavity of hot water water inlet and cold water has increased a pressure guide hole; make and go into isobaric cavity at the isobaric cavity of hot water water inlet with cold water and be under the identical hydraulic pressure; make moving up and down of mangetic core assembly become easy; reduced the thrust of thermometer bulb, thereby made the more reliable work of self-supporting thermostatic water mixing valve.
The beneficial effects of the utility model are, make the water-exit temperature of self-supporting thermostatic water mixing valve not be subjected to the influence of water pressure fluctuations, have guaranteed the precision of self-supporting thermostatic water mixing valve water-exit temperature.

Embodiment
In the drawings; a spring bracket (1) is installed in the lower end of valve body (2); the central authorities of the upper end of spring bracket (1) are placed with thermometer bulb (18); thermometer bulb (18) links to each other with the lower end of mangetic core assembly (16); there is a pressure guide hole (5) in the central authorities of mangetic core assembly (16); the central authorities of pressure guide hole (5) are placed with thermometer bulb push rod (13); the lower end of thermometer bulb push rod (13) and thermometer bulb (18) are to connecting; the upper end of thermometer bulb push rod (13) links to each other with thermometer bulb protection assembly (8); the center of mangetic core assembly (16) connects seal spool pad (6); the inside of the outside valve body (2) of mangetic core assembly (16) is placed with valve core housing (4); mangetic core assembly (16) can move up and down in valve core housing (4) inside; in the top and bottom of mangetic core assembly (16) respectively and valve core housing (4) slipper seal; the top and bottom of seal spool pad (6) and mangetic core assembly (16) form isobaric cavity (15) respectively; isobaric cavity (15) communicates with hot water water inlet (17) and cold water water inlet (3) respectively; upper end at valve core housing (4) links to each other with valve gap (14); valve gap (14) links to each other with the upper end of valve body (2); in the central authorities of valve gap (14) lifting bar (9) is housed; thermometer bulb protection assembly (8) is equipped with in the central authorities of lifting bar (9); handle base (12) is equipped with on the top of lifting bar (9); handle (11) and handle retaining screw (10)
Hot and cold water enters the isobaric cavity (15) of back separately by hot water inlet (17) and cold water inlet (3) respectively in use, by individual isobaric cavity (15) separately through seal spool pad (6) mix the back by the lower end of valve body (2) thermometer bulb (18) thermometric after water outlet flow out, when the detected temperature of thermometer bulb (18) is higher than setting temperature, medium expanded by heating in the thermometer bulb (18) promotes thermometer bulb push rod (13), because thermometer bulb push rod (13) thus can't move and drive mangetic core assembly (16) and seal spool pad (6) moves down the hot water minimizing that makes through isobaric cavity (15) together, cold water through isobaric cavity (15) is increased, temperature is reduced; When the hydraulic pressure of water inlet takes place to increase or reduces, act on mangetic core assembly (16) and seal spool pad (6) and increase simultaneously or reduce owing to enter into the water of isobaric cavity (15), thereby the temperature that has guaranteed water outlet is not subjected to because of hydraulic pressure increase or the influence that reduces.
In addition, because the centre at hot water inlet (17) back isobaric cavity (15) and cold water inlet (3) the isobaric cavity in back (15) has increased a pressure guide hole, make and go into (3) isobaric cavity (15) with cold water at the isobaric cavity in hot water water inlet (17) back (15) and be under the identical hydraulic pressure, make moving up and down of mangetic core assembly (16) become easy, reduced the thrust of thermometer bulb (18), thereby made the more reliable work of self-supporting thermostatic water mixing valve.
