Abstract

The invention provides a reversing valve which comprises a valve body provided with a cavity, an inlet channel and a plurality of outlet channels, and the inlet channel and the outlet channels are both communicated with the cavity; the valve element assembly is movably arranged in the cavity, the first side of the valve element assembly is arranged towards the multiple outlet channels, and the second side of the valve element assembly is arranged towards the inlet channel; the cross section area of the inlet channel is S1, when the valve element assembly is located below the inlet channel, an exhaust channel is formed between the projection, on the second side of the valve element assembly, of the end of the inlet channel and the end of the inlet channel, the side wall area of the exhaust channel is S2, and S1 / S2 is larger than or equal to 1. Through the technical scheme provided by the invention, the problem that a reversing valve in the related technology is prone to reversing failure can be solved.

Description

technical field [0001] The present invention relates to the technical field of reversing valves, in particular, to a reversing valve. Background technique [0002] like figure 1 As shown in the figure, the existing four-way valve structure mainly includes a valve cavity and an inlet pipe 2, a first outlet pipe 3 and a second outlet pipe 4 communicating with the valve cavity. Block 1, the valve cavity can be communicated with the first outlet pipe 3 or with the second outlet pipe 4. During the reversing process, when the slider 1 moves to the middle position (below the inlet channel 2), the first outlet pipe 3, the second outlet pipe 4 and the low-pressure pipe are connected with each other, which causes the pressure in the valve cavity to be released quickly, and is connected with the inlet pipe. The supply pressure of the capillary connected to the pipeline 2 is insufficient, which reduces the thrust on the left and right sides of the piston baffle. In severe cases, the s...
