Abstract

The invention discloses an electromagnetic changeover valve. According to the electromagnetic changeover valve, the first side of a fixing frame is provided with a retaining ring type fixing frame body, the middle of the fixing frame is provided with a connecting support, and the second side of the fixing frame is provided with a round hole fixing frame body. The retaining ring type fixing frame body, the connecting support and the round hole fixing frame body are connected into one. The connecting support or the retaining ring type fixing frame body is fixed to a main valve body. One side, close to the end portion of the valve body, of the valve body of a control valve is arranged in the round hole fixing frame body in a penetrating mode, and the other side connected with a guide pipe is fixed to the retaining ring type fixing frame body. The electromagnetic changeover valve avoids the problem that due to poor deformation of the fixing frame and unstable location shift in the riveting process, products are not good, lowers the complexity of the riveting process, and greatly improves the production efficiency, the utilization rate of raw materials of the valve body of the control valve is reduced, the installation height of the valve body of the control valve and the main valve body is ensured, the performance consistence of the products is improved, and the production cost is lowered.

Description

Technical field: [0001] The invention relates to the technical field of electromagnetic switching valves used in the air-conditioning and refrigeration industry, in particular to an electromagnetic switching valve. Background technique [0002] Electromagnetic switching valve is an important part of heat pump air conditioner, suitable for central and split air conditioners, etc. The action of the existing electromagnetic switching valve is to use the high and low pressure difference in the system, and use the switching of the electromagnetic coil of the control valve to switch the flow path of the main valve body 1, and then realize the change of the refrigerant flow direction in the system. The control valve is connected with the main valve body 1 through a fixing bracket 6 . The existing fixing frame 6 is riveted at both ends, which has technical problems such as large riveting deformation and complicated riveting process, and the cooperation stability with the control va...
