The function and working principle of the solenoid valve of the refrigerator

The function of the solenoid valve is to cut off the circuit of the system when the compressor is stopped to avoid liquid hammer when the compressor is started next time. Generally used in larger refrigeration systems. In the refrigerator equipment, the solenoid valve is used to change the direction of cooling and heating. The role of the expansion valve in the four core elements is to adjust the refrigeration pressure to achieve the effect of evaporating the refrigerant. Here we have another easy-to-understand explanation: the valve controlled by the electromagnet is referred to as the solenoid valve for short. This type of valve is widely used in automatic control systems. It is a key component of control execution.

Its working principle is: to open several holes in different positions on a valve body, each hole is connected to a different oil pipe, and then use electromagnetic induction to control the movement of the valve stem to control which hole is blocked or which hole to let air out. In order to achieve the purpose of control. Solenoid valves can cooperate with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. This is also an aspect where solenoid valves are widely used.
