Embodiment 2

[0041] The working process of the electronic expansion valve in the second embodiment is similar to the working process of the electronic expansion valve in the first embodiment. The difference between the working process of the electronic expansion valve in the second embodiment and the first embodiment is that a The top of the abutment sleeve 73 and the valve needle 20 has a raised portion 24 that cooperates with the abutment sleeve 73 . When the rotor 60 reverses, the threaded mandrel 70 starts to move upwards, and then the threaded mandrel 70 drives the top sleeve 73 to move upwards. Then, the upper surface of the abutment sleeve 73 abuts against the lower surface of the protrusion 24, and will bring the valve needle 20 to move upward until it returns to its original position.

Embodiment 3

[0042] The difference between the electronic expansion valve (not shown) of the third embodiment and the above-mentioned embodiments lies in the installation position of the noise reducing part. Specifically, the noise reduction part is arranged in the valve seat core, and the inner wall of the noise reduction part cooperates with the outer wall of the main body part. The above-mentioned structure is simple and easy to implement, and the above-mentioned structure can keep a predetermined distance between the inner wall of the valve seat core and the main body, thereby reducing friction and impact between the inner wall of the valve seat core and the main body, thereby reducing noise and improving user experience.

[0043] In the present application, a refrigeration device is also provided. The refrigeration device according to the present application includes an electronic expansion valve, and the electronic expansion valve is the above-mentioned electronic expansion valve. S...

Abstract

The present invention provides an electronic expansion valve and refrigeration equipment with the electronic expansion valve, wherein the electronic expansion valve includes: a valve seat core with a valve port; The valve needle has a closed position for closing the valve port and an open position for avoiding the valve port; the noise reduction part is arranged between the inner wall of the valve seat core and the main body, and the noise reduction part is composed of non- Made of metal material; the driving part drives the valve needle to move between the closed position and the open position. The technical solution of the invention can effectively solve the problem of high noise of the electronic expansion valve in the prior art.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to an electronic expansion valve and a refrigeration device having the same. Background technique [0002] In the field of refrigeration, an electronic expansion valve is used, such as figure 1 As shown, the electronic expansion valve is mainly composed of a coil and a valve body, wherein the valve body is composed of a valve seat, a valve seat core 1, a first connecting pipe 3, a second connecting pipe 4, a casing, a rotor part 5, a nut assembly 6, a screw rod The assembly 7, the valve needle 8, the coil fixing frame 9 and other components are composed. In the existing structure, both the valve needle 8 and the valve seat core 1 are metal. When the electronic expansion valve works, the valve needle 8 moves back and forth in the inner hole of the valve seat core 1 . During the continuous valve opening and closing process of the electronic expansion valve, there will be friction and i...
