Abstract

The invention discloses a novel four-way valve which comprises a valve body and a reversing valve block. An annular valve seat is coaxially arranged in the middle in the valve body, a high-pressure air inlet is formed in the middle of the upper side of the valve body, an air suction connector is correspondingly formed in the lower side of the valve body, a first heat exchanger connector and a second heat exchanger connector are formed in the two sides of the air suction connector respectively, and reversing air inlets are symmetrically formed in the two ends of the upper side of the valve body. A reversing valve block matched with the bottom of the inner wall of the annular valve seat is arranged in the annular valve seat in a sliding mode, a reversing sliding rail arranged in the axis direction of the valve body is arranged on the reversing valve block, reversing pistons in sliding fit with the valve body are arranged at the two ends in the valve body, and connecting discs are symmetrically arranged at the two ends of the reversing sliding rail. The connecting disc is connected with the reversing piston through a bolt; detachable end covers are symmetrically arranged at the two ends of the valve body, and O-shaped sealing rings are arranged between the ends of the valve body and the end covers.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a novel four-way valve. Background technique [0002] Generally, in the air conditioning system, the refrigerant is converted between low temperature and low pressure and high temperature and high pressure through the compression of the compressor and the throttling effect of the throttling element, and the four-way valve is used to change the flow from the compressor to the heat exchanger. road, and through the heat exchange between the indoor heat exchanger and the outdoor heat exchanger and the surrounding environment, the effect of cooling or heating is realized. Among them, the four-way valve plays the role of flow path switching in the system. When the refrigerant at the compressor exhaust port is first introduced into the indoor heat exchanger, the air conditioner realizes heating operation; When the refrigerant is introduced into the outdoor heat exchanger first...
