Solenoid valve is a kind of shut-off valve that relies on electromagnetic force automatic switch. It is an automatic basic component used to control fluid. It is an actuator and is widely used in hydraulic systems and pneumatic systems.
The solenoid valve can be used with different circuits to achieve the desired control, while the precision and flexibility of the control can be guaranteed.
The principle of the solenoid valve is actually very simple. When the solenoid valve is not powered, the valve needle is gambling under the action of the spring, and the solenoid valve is in the off state.
When the coil is powered on, the coil generates a magnetic force, the valve core is lifted up against the spring force, the valve passage is opened, and the solenoid valve is in an on state.
In the refrigerating and air-conditioning device, the commonly used solenoid valve is used as a regulating mechanism or a safety protection device for the remote stop valve, the two-position adjustment system.
It can be applied to various gases, liquid refrigerants, lubricating oils and other media.
For some early small and medium-sized units, the solenoid valve was connected in series with the liquid line in front of the throttling device and connected to the compressor with the same start switch.
When the compressor is turned on, the solenoid valve is opened and the system piping is turned on to make the air conditioning system operate normally.
When the compressor is stopped, the solenoid valve automatically cuts off the liquid line, preventing the refrigerant liquid from continuing to flow to the evaporator, preventing the refrigerant from being hit when the compressor starts again.
In the central air conditioning (multi-line) system, the solenoid valve is more widely used in the system, including: the pilot valve for controlling the four-way valve, the exhaust gas return line of the compressor, the cooling circuit, and the like.
Solenoid valves are installed in these positions, and the flow of the refrigerant is controlled by the opening of the solenoid valve.
