Abstract

The invention discloses an electronic expansion valve. The electronic expansion valve is provided with two valve cavities, a valve port part of a valve seat is provided with a divergent area on one side of a valve port, the divergent area is approximately horn-shaped, the wall thickness h of the valve port part close to the valve port is smaller than the wall thickness H of the valve port part away from the valve port, and in this way, the wall thickness h of the valve port part close to the valve port can be correspondingly reduced. Therefore, when a refrigerant in the electronic expansion valve flows in the first flowing direction, the refrigerant enters the diverging area after passing through the valve port, due to the arrangement of the diverging area, flowing of the refrigerant passing through the valve port can be improved, flowing noise of the refrigerant is reduced, and the requirement of some systems for improving the noise is met.

Description

【Technical field】 [0001] The invention relates to the technical field of refrigeration control, in particular to an electronic expansion valve. 【Background technique】 [0002] The refrigeration system includes a compressor, a throttling element, two heat exchangers and other components. The throttling element can use an electronic expansion valve for throttling adjustment of the refrigerant. Using an electronic expansion valve can achieve relatively precise control and improve system energy efficiency. . When the refrigerant passes through the electronic expansion valve, some noise may be generated. Improving the noise of the refrigerant passing through the electronic expansion valve has been a technical topic that has been researched by the relevant technical personnel of the electronic expansion valve and refrigeration system for a long time. 【Content of invention】 [0003] The purpose of the present invention is to provide an electronic expansion valve for improving t...
