The control unit 30 is connected to the sensing module 10 and the solenoid valve module 20 respectively. The sensing module 10 detects the medium temperature and the flow rate value in the flow channel, and then returns a signal to the control unit 30. The sensing module 10 further adjusts the current of the output of the power module 40 to the solenoid valve module 20 by the control unit 30, and controls the relative position of the valve body 21 and the valve seat 22 by changing the magnitude of the current.

Please refer to the first and second figures. The sensing module 10 includes a temperature sensing unit and a flow sensing unit for monitoring temperature and flow changes of the medium in the flow channel, respectively. When the temperature of the medium changes by a certain value, the sensing module 10 can detect the change and then send a signal to the control unit 30, and the control unit 30 adjusts the current through the coil 23, thereby controlling the electromagnetic valve mode. Group 20.

The solenoid valve module 20 includes a first-class circuit, a valve body 21, a valve seat 22, and at least one coil 23, an adjusting screw 25 and an elastic member 26. The solenoid valve module 20 is a normally closed solenoid valve or a normally open solenoid valve. In other words, when the medium is at normal temperature, the valve body 21 is respectively in a closed position or an open position. The valve body 21 and the valve seat 22 are detachably coupled, and the coil 23 is adjacent to the side of the valve body 21, and the coil 23 is used for receiving a current signal to adjust its relative position.

In more detail, the valve body 21 and the valve seat 22 together define an opening through which the medium passes through the flow passage and the opening, and the elastic member 26 abuts against the adjusting screw 25 and the valve body 21, respectively, and the valve body 21 is affected by the magnitude of the current passing through the coil 23. Reciprocating between the open position and the closed position, respectively. Furthermore, the adjusting screw 25 is disposed on the side of the elastic member 26, and by changing the relative position between the adjusting screw 25 and the elastic member 26, the elastic position of the elastic member 26 against the valve body 21 can be controlled, thereby affecting the coil. The balance between the electromagnetic force 50 of 23 and the spring force 51 of the elastic member 26.

Further, when the sensing module 10 monitors that the temperature of the medium rises, that is, the signal is sent to the control unit 30 to increase the distance between the valve body 21 and the valve seat 22, in other words, the opening is increased to make the medium flow. The amount of the opening is increased, and the flow sensing unit synchronously monitors the flow rate, and the medium flow rate is adjusted to speed up the cycle, thereby lowering the temperature of the medium. Furthermore, the number of the coils 23 in this embodiment is three, and the control unit 30 receives or outputs a signal by using a binary code, thereby changing the distance between the valve body 21 of the solenoid valve module 20 and the valve seat 22.
