Description

Technical Field

[0002] An air conditioning four-way valve structure is a key component for controlling the flow direction and distribution of refrigerant in a refrigeration cycle. The four-way valve is a control valve with four oil ports. The four-way valve is an indispensable component in refrigeration equipment. Its working principle is that when the solenoid valve coil is in a power-off state, the pilot slide valve moves left under the drive of the right compression spring, and the high-pressure gas enters the capillary tube and then enters the right end piston chamber. On the other hand, the gas in the left end piston chamber is discharged. Due to the pressure difference at both ends of the piston, the piston and the main slide valve move left, so that the exhaust pipe is connected to the outdoor unit connecting pipe, and the other two connecting pipes are connected to form a refrigeration cycle.

[0003] In the prior art, the electromagnetic four-way reversing valve used in some air conditioners has a complex structure and is easily damaged during use. In particular, the internal electromagnetic valve coil is easily burned out. The solenoid valve core is enclosed in the pipeline valve body. Once the valve core is damaged, the valve must be removed from the pipeline for replacement. The replacement requires the use of external tools, which is time-consuming and labor-intensive. Therefore, an air conditioner four-way valve structure is proposed to solve the above problems. Utility Model Content
