[0024] Please refer to Figure 1-Figure 4 , figure 1 is a schematic structural diagram of the first embodiment of the electronic expansion valve, figure 2 is a partially enlarged schematic diagram, image 3 yes figure 1 Partial cross-sectional schematic diagram of the electronic expansion valve, mainly including the valve seat and valve body parts, so that the structure of the valve port can be clearly understood; Figure 4 It is a schematic cross-sectional view of the valve seat part.
[0025] It should be pointed out that the following technical solutions are aimed at the specific structure of the electronic expansion valve. This application mainly improves the flow channel structure of the refrigerant to improve the noise of the refrigerant flow, and specifically improves the structure of the valve cavity and valve port. . For other parts of the electronic expansion valve, such as magnetic rotor assembly, nut assembly, stop device and other parts, there is no limitat...
