What is the function of the refrigeration solenoid valve? How does the refrigeration solenoid valve work?

Refrigerating solenoid valve What is the role of

The refrigeration system is divided into high pressure and low pressure, liquid and gas. In order to prevent the high-pressure liquid refrigerant from impacting the compressor after the compressor is shut down, Solenoid valve to protect the system. When the compressor starts, the system pressure is in a balanced state so there is no impact. This When the solenoid valve is powered on, the compressor starts and the refrigerant circulates for refrigeration.

< span style="font-size: 16px;">When the compressor is shut down, the power is cut off or the solenoid valve is quickly cut off after stopping. The refrigerant on the high-pressure side will not return to the compressor in the opposite direction, but will pass through the rotating ring. direction through the compressor, and slowly the entire refrigeration system slowly returns to equilibrium with the compressor's stop pressure.

Working principle of refrigeration solenoid valve

When cooling When the equipment is started, the solenoid coil generates electromagnetic force to open the valve. When the coil in the solenoid head is energized, the coil and the armature generate an induced magnetic field. The armature drives the valve needle to move upward, the valve hole is opened, and the fluid flows normally. When the set temperature is reached and the coil in the solenoid head is powered off, the magnetic field disappears, the armature falls due to rain and spring force, the valve needle closes the valve hole, and the fluid stops flowing.

The solenoid valve is a valve that controls the automatic on and off of the refrigerant in the refrigeration system. Solenoid valves can be divided into two types: direct-acting and indirect-acting. Solenoid valves used in commercial refrigeration equipment are generally direct-acting.

Solenoid valveIt consists of two parts: the valve body and the solenoid head, which are generally direct-acting. The so-called direct opening and closing solenoid valve uses the armature in the solenoid head to directly control the opening and closing of the valve hole. The hole diameter is generally between 6-22mm.
