Brief introduction of three-flower four-way valve
The three-flower four-way valve is a control valve with four ports.The four-way valve is an indispensable part of the refrigeration equipment. Its working principle is that when the solenoid valve coil is in the de-energized state, the pilot slide valve is driven by the right compression spring to move to the left, and the high pressure gas enters the capillary tube and enters the right piston chamber. On the one hand, the gas in the left piston cavity is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move to the left, so that the exhaust pipe communicates with the outdoor unit pipe, and the other two pipes communicate to form a refrigeration cycle.
When the solenoid valve coil is energized, the pilot slide valve overcomes the tension of the compression spring and turns to the right under the magnetic force generated by the solenoid coil. The high-pressure gas enters the capillary tube and enters the left piston cavity. On the other hand, the gas in the right piston cavity is discharged, Due to the pressure difference between the piston ends, the piston and the main slide valve turn right, so that the exhaust pipe and the indoor machine take over, and the other two pipes are connected to form a heating cycle.
When the main slide valve is in the middle position, the three connecting pipes e, s, and c ventilate each other to generate an intermediate flow. At this time, the refrigerant in the high-pressure pipe in the compressor can directly flow back to the low-pressure pipe. The function of the intermediate flow is to achieve a good pressure relief function when the main spool valve is in the intermediate position, and to prevent the system from being damaged by high pressure.
The above is the whole content of the three-flower four-way valve introduced to you . I hope you can have a better understanding of it after reading it.
