Abstract
The invention discloses a thermostatic valve for a water heater. The thermostatic valve comprises a valve body, a cold water inlet, a hot water inlet and a water outlet are formed in the valve body, the cold water inlet, the hot water inlet and the water outlet are communicated with a cold water thermistor, a hot water thermistor and a water outlet thermistor respectively, the cold water thermistor, the hot water thermistor and the water outlet thermistor are arranged at one end of the valve body, a turbine rotor with a magnet is arranged in the hot water inlet, the outer wall of the hot water inlet is provided with an insertion groove used for being connected with a Hall element in an inserted mode, and a ceramic valve element, an adjusting gear and a stepping motor are sequentially connected from an inner cavity of the valve body to the other end of the valve body. By means of the structure, rotation frequency of the stepping motor can be automatically controlled, and hot water inlet amount can be automatically adjusted through the ceramic valve element so that automatic thermostatic control of outflow water temperature can be achieved, and the thermostatic valve is convenient and safe to use.
Description
Technical field
The present invention relates to thermostatic valve, particularly a kind of thermostatic valve for water heater.
Background technique
The water-exit temperature of existing water heater regulates, and is all generally that water-exit temperature cannot accurately be held by manually regulating, adjusting is got up cumbersome, meanwhile, and because hydraulic pressure is often unstable, cause water-exit temperature can not keep constant, while existing temperature to raise suddenly, cause the hidden danger that people scalds.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of thermostatic valve for water heater, and the automatic constant-temperature that can realize water-exit temperature regulates, and uses not only convenient but also safety.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of thermostatic valve for water heater is provided, comprise valve body, valve body is provided with cooling water inlet, hot water inlet and goes out water out, cooling water inlet, hot water inlet and go out water out, the cold water thermistor set with valve body one end, hot water thermistor and water outlet thermistor are communicated with respectively, are provided with the turbine rotor of carry magnet in hot water inlet, and hot water inlet outer wall is provided with the slot of grafting Hall element; The other end from the inner chamber of valve body to valve body, is connected with ceramic valve core, adjusting gear and stepper motor successively.
Adopt the thermostatic valve for water heater of said structure, due to can be by the rotational frequency of automatic control step motor, and and then by ceramic valve core, automatically regulate the size of hot water flow of inlet water, thereby the automatic constant-temperature that can realize water-exit temperature regulates, and uses not only convenient but also safety.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the three-dimensional split figure of described invention;
Fig. 2 is the stereogram of described invention.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of thermostatic valve for water heater is provided, comprise valve body 1, valve body 1 is provided with cooling water inlet 2, hot water inlet 3 and goes out water out 4, cooling water inlet 2, hot water inlet 3 and go out water out 4, cold water thermistor 5, hot water thermistor 6 and the water outlet thermistor 7 set with valve body 1 one end is communicated with respectively, and in fact cold water thermistor 5, hot water thermistor 6 and water outlet thermistor 7 are cold water temperature sensor, hot water temperature's sensor and water-exit temperature sensor.In hot water inlet 3, be provided with the turbine rotor 8 of carry magnet, hot water inlet 3 outer walls are provided with the slot 10 of grafting Hall element 9, Hall element 9 is existing a kind of magnetic quantity transducers based on Hall effect, can detect magnetic field and variation thereof with it, turbine rotor 8 and the common hot water flow sensor that forms of Hall element 9.The other end from the inner chamber of valve body 1 to valve body 1, is connected with ceramic valve core 11, adjusting gear 12 and stepper motor 13 successively.
During use, can be in advance by the cold and hot mixing water water temperature flowing out from going out water out 4, be set as a certain numerical value as 38 ℃, the cold water flow entering in valve body 1 from cooling water inlet 2 immobilizes, and enter the hot water flow in valve body 1 from hot water inlet 3, can change along with the variation of hydraulic pressure, when hot water flow increases, hot water flow sensor sends to master board by pulse signal, master board pulse signals and cold water thermosensitive resistance, hot water thermosensitive resistance and water outlet thermosensitive resistance are compared, and then the rotational frequency of automatic control step motor 13, make it to reduce, stepper motor 13 regulates ceramic valve core 11 by adjusting gear 12 interlocks thereupon, the water yield that hot water flows out through ceramic valve core 11 is reduced, can make the mixed water temperature of hot water and cold water be held constant at 38 ℃, otherwise, when hot water flow reduces, hot water flow sensor sends to master board by pulse signal, master board pulse signals and cold water thermosensitive resistance, hot water thermosensitive resistance and water outlet thermosensitive resistance are compared, and then the rotational frequency of automatic control step motor 13, make it to increase, stepper motor 13 regulates ceramic valve core 11 by adjusting gear 12 interlocks thereupon, the water yield that hot water flows out through ceramic valve core 11 is increased, can make equally the mixed water temperature of hot water and cold water be held constant at 38 ℃.
Above-described embodiment is the preferred embodiments of the present invention, and all and the similar structure of the present invention and the equivalence of doing change, and all should belong to protection category of the present invention.
