Electromagnetic four-way reversing valve

Abstract

The invention provides an electromagnetic four-way reversing valve. The electromagnetic four-way reversing valve comprises a main valve, a pilot valve and an electromagnetic coil, the main valve comprises a main valve body, a main valve seat, two pistons, a guide frame, a slider, an E connecting pipe, an S connecting pipe, a C connecting pipe and a D connecting pipe, wherein the slider is arranged on the guide frame, the pistons are connected with two ends of the guide frame respectively, an inner cavity of the main valve is divided into three cavities by the pistons, the E connecting pipe, the S connecting pipe and the C connecting pipe respectively penetrate mounting holes of the main valve body to be connected with mounting holes of the main valve seat, the D connecting pipe is connected with a D connecting pipe mounting hole in the main valve body, the mounting holes of the main valve seat are elongated holes along the length direction of the main valve seat, a pipe orifice shaft of the D connecting pipe is matched with the shape of the D connecting pipe mounting hole, and pipe orifice shapes of the E connecting pipe, the S connecting pipe and the C connecting pipe are matched with the shape of the mounting holes of the main valve seat. The size and manufacturing cost of the electromagnetic four-way reversing valve can be reduced.

Description

technical field [0001] The invention relates to electromagnetic valve technology, in particular to an electromagnetic four-way reversing valve. Background technique [0002] The electromagnetic four-way reversing valve is mainly used to switch the flow direction of the refrigerant in the air conditioning system, so as to realize the cooling and heating mode switching of the air conditioning system. [0003] figure 1 It is a structural schematic diagram of an electromagnetic four-way reversing valve in the prior art; as figure 1 As shown, an existing electromagnetic four-way reversing valve is assembled from three parts: a main valve 1, a pilot valve 2 and an electromagnetic coil 3. The working principle of the electromagnetic four-way reversing valve is as follows: [0004] When the air conditioner needs cooling operation: the electromagnetic coil 3 is powered off, and the high-pressure refrigerant coming out of the compressor exhaust port is divided into two paths, one p...
