Category: Reversing Valve

The  reversing valve, hydraulic valve terminology, is a control valve with four ports . The four-way valve is an indispensable component in the refrigeration equipment. Its working principle is that when the solenoid valve coil is in the power-off state, the pilot spool valve is driven to the left by the right compression spring, and the high-pressure gas enters the capillary tube and enters the right-end piston chamber. On the one hand, the gas in the left piston chamber is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main spool are moved to the left, so that the exhaust pipe communicates with the outdoor unit, and the other two nozzles communicate with each other to form a refrigeration cycle.
When the solenoid valve coil is energized, the pilot spool valve is moved to the right by the magnetic force generated by the electromagnetic coil against the tension of the compression spring, and the high-pressure gas enters the capillary tube and enters the left-end piston chamber. On the other hand, the gas in the right-end piston chamber is discharged due to There is a pressure difference between the two ends of the piston, and the piston and the main spool valve are moved to the right, so that the exhaust pipe communicates with the indoor unit, and the other two pipes communicate with each other to form a heating cycle.
