Electric valve and its coil fixing frame

Abstract

The invention discloses an electric valve and a coil fixing frame thereof. The coil fixing frame of the electric valve comprises a first flat plate portion, which is used for supporting a coil, and a sleeve portion which is fixedly connected to the first flat plate portion, wherein the casing of the valve body of the electric valve is sleeved with the sleeve portion, and the sleeve portion is further connected with a second flat plate portion; the valve base of the electric valve is fixedly sleeved with the second flat plate portion. According to the structural design of the coil fixing frame of the electric valve, interaction among assembly processes can be avoided, the assembly processes are reduced, and the design cost and the process cost are reduced, so that the assembly qualification rate is improved, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of flow regulating valves, in particular to an electric valve and a coil fixing frame thereof. Background technique [0002] In various refrigeration and heating equipment or other occasions where fluid flow needs to be adjusted, flow regulating valves are usually used, and electric valves are one type of flow regulating valves. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a common electric valve in the prior art. [0004] figure 1 The electric valve shown mainly includes a valve seat 11, a valve body casing 12 and a fixing frame 13 welded together with the valve seat 11; in addition, a cover (not shown) is welded on the valve seat 11, and the valve body casing 12 It is sleeved on the cover to realize the connection with the valve seat 11. [0005] The outer wall of the valve seat 11 is provided with a positioning groove 111 extending in the circumferential direct...

AI Technical Summary

Problems solved by technology

[0007] It can be seen that the fixing of the bobbin 13 and the valve seat 11 requires not only grooves on the valve seat 11, but also a welding process to be performed after the two are matched to be reliable, and the technological process is more complicated; the cooperation of the valve seat 11 and the cover is also necessary. Through welding; the coil frame 13 is used to fix the coil, the cover is used to fix the valve body shell 12, and the coil is set on the valve body shell 12, so the distance between the coil frame 13 and the cover is very close. When assembling like this, Any one of the coil frame 13 and the cover is welded to the valve seat 11 first, which will have an adverse effect on the welding of the other to the valve seat 11, thereby reducing the qualified rate of the electric valve assembly and affecting the reliability of the electric valve.
