Description

Technical Field

[0001] The utility model belongs to the technical field of angle valves and relates to a three-way liquid-dividing angle valve for a central air conditioner. Background Art

[0002] The three-way liquid-separating angle valve is a common control valve in central air-conditioning systems, which is mainly used to adjust and control the flow and direction of refrigerant. Its main function is to separate the moisture and impurities in the refrigerant through the liquid separation effect when the refrigerant flows from the high-pressure side to the low-pressure side during the operation of the air-conditioning system, so as to ensure the normal operation of the refrigeration system. The three-way liquid-separating angle valve is usually composed of a valve body, a valve core, a sealing ring, a handle and other parts. Among them, the valve body is the main part of the entire valve, with channels and valves inside; the valve core is the key component for controlling the flow of refrigerant, which can be opened or closed as needed; the sealing ring is used to ensure that the refrigerant will not leak during the opening or closing of the valve; the handle is a tool for manually operating the valve. When using the three-way liquid-separating angle valve, it is necessary to reasonably adjust the opening of the valve according to the actual situation of the air-conditioning system to achieve the best cooling effect. At the same time, it is also necessary to regularly check and maintain the valve to ensure its normal operation and avoid affecting the operating efficiency of the air-conditioning system. The regulating valve core in the existing three-way angle valve is usually an embedded structure, which requires an additional hexagonal wrench for adjustment. The operation steps are relatively cumbersome and the service life is not high. Utility Model Content
