Summary of the invention
The purpose of this invention is to provide that the control of a kind of water-exit temperature is accurately reliable, long service life, double-control thermostatic controller that automatization level is high.
The present invention is provided with cold and hot modulating valve and electromagnetic switch valve, and the water outlet of cold and hot modulating valve is communicated with the water intake of electromagnetic switch valve;
Cold and hot modulating valve is provided with valve body, spool, motor, control circuit board and temperature transducer, valve body is provided with cold water inlet channel, hot water inlet channel, valve pocket and mixed water water outlet, spool is located in the valve pocket, spool cooperates with the rotary seal of valve pocket inwall, spool seals on the cold water inlet channel port and hot water inlet channel port that is pressed on the wall of valve pocket chamber, motor and control circuit board be located on the valve body and with the valve pocket seal isolation, the rotating shaft of motor is connected with spool, temperature transducer is located at and is mixed in the water water outlet, and temperature transducer is connected with electromagnetic switch valve;
Electromagnetic switch valve is provided with valve body, coil, magnet, depression bar, spool and Sealing, and valve body is provided with and mixes water inlet channel and mixed water water outlet, and Sealing and spool are located at the place that is communicated with of mixing water inlet channel and mixed water water outlet; Depression bar is located in the coil, and depression bar is pressed on the spool, mixes the water inlet channel and is communicated with the mixed water water outlet of cold and hot modulating valve.
The motor of cold and hot modulating valve preferably is connected by electric machine support and valve body.
The rotating shaft of the motor of cold and hot modulating valve preferably is connected with spool by crossover sub.
The valve pocket center line of the motor center line of cold and hot modulating valve, center spool line and valve body preferably overlaps.
The rotating shaft of the motor of cold and hot modulating valve next door preferably is provided with limit switch, and the rotating shaft that limit switch is used to limit motor is because of excessively rotation of inertia, thereby the spool that is connected with rotating shaft is accurately located.
The depression bar center line of electromagnetic switch valve preferably overlaps with the center spool line.
The Sealing of electromagnetic switch valve is preferably the stair-stepping seal ring of annulus, and the inner ring and the spool of Sealing are connected, and the outer ring of Sealing is fixed on the valve body.
Because the present invention is provided with cold and hot modulating valve, cold and hot modulating valve is by the driven by motor valve core rotation, the rotation program of motor can be set on the control circuit board as requested in advance, spool can make the cold water inlet channel of valve body and the water intake end open area of hot water inlet channel change during rotation, thereby can change the proportionate relationship of cold water inflow and hot water inflow, reach and regulate the water-exit temperature that mixes the water water outlet.Because the present invention is provided with electromagnetic switch valve, when the water-exit temperature of the mixed water water outlet of cold and hot modulating valve satisfies regulation and requires, temperature transducer passes to electromagnetic switch valve with signal, the electromagnetic switch valve energising, depression bar picks up spool, Sealing is with moving on the spool and produce distortion, makes to mix the water inlet channel and mixed water water outlet communicates, and realizes water outlet.When the water-exit temperature of the mixed water water outlet of cold and hot modulating valve produces fluctuation when surpassing regulation and requiring, temperature transducer passes to electromagnetic switch valve with signal, the electromagnetic switch valve outage, magnet does not have suction, depression bar is pressed on the spool, and then Sealing is isolated mixed water inlet channel and mixed water water outlet, stops water outlet.This moment, temperature transducer also passed to signal the sensitive switch of motor, drove spool and carried out minor adjustments, and after reaching water-exit temperature and satisfying regulation and require, electromagnetic switch valve can be opened water outlet again.
This shows that cold and hot modulating valve and electromagnetic switch valve have dual adjusting function, can reach constant-temperature effluent, and water-exit temperature control is accurately reliable, the purpose that automatization level is high.Again since the spool of cold and hot modulating valve and valve pocket inwall for being rotatably assorted, with the linear type comparison that is slidingly matched, its frictional force is little, quality of fit height, so longer service life of the present invention, degree of regulation is higher.
