Electromagnetic valve connecting device, electromagnetic valve and heat exchange device

Abstract

The invention discloses an electromagnetic valve connecting device, which is used for connecting a main valve (1) and a pilot valve (2) of an electromagnetic valve and comprises a bracket (3) and a connecting frame (4), wherein the bracket (3) is connected with the main valve (1); the connecting frame (4) is connected with the pilot valve (2). In the invention, the bracket (3) is matched with the connecting frame (4) through an opening and a bump which are arranged on corresponding side walls to realize connection, so that the structural design of matched folding edge and groove in the prior art is changed, a manual compression step is saved, assembly difficulty and labor intensity are reduced, and assembly efficiency and assembly stability are improved. In addition, the invention discloses the electromagnetic valve comprising the electromagnetic valve connecting device. Besides, the invention discloses a heat exchange device comprising the electromagnetic valve.

Description

technical field [0001] The invention relates to the technical field of solenoid valves, in particular to a connection device for solenoid valves. In addition, the present invention also relates to a solenoid valve comprising the above solenoid valve connection device. Furthermore, the present invention also relates to a heat exchange device comprising the above solenoid valve. Background technique [0002] The electromagnetic reversing valve is a fluid control component. Its main function in heat exchange devices such as heat pump air-conditioning systems is to change the direction of refrigerant flow, thereby realizing mutual conversion between cooling and heating. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical solenoid valve in the prior art. [0004] The solenoid valve in the prior art includes a main valve 1' and a pilot valve 2', the main valve 1' is connected with a bracket 3', and the pilot valve 2' is connected with...

AI Technical Summary

Problems solved by technology

[0010] It can be seen from the above that when the bracket 3' is assembled with the connecting frame 4', it is necessary to use manual crimping to crimp and fix the first hem 5'1 and the second hem 5'2. This structural design leads to Assembly is difficult, inefficient, and increases labor intensity

In addition, even if the first folded edge 5'1 and the second folded edge 5'2 are crimped and fixed, after working for a period of time, the above-mentioned folded edges are easy to slide in the groove, thus causing the bracket 3' and the connecting frame 4' low assembly stability between
