WIPO Patent Application WO/2023/005178
Kind Code:
A1
Abstract:
An electric valve, comprising a valve seat assembly (10) and a nut assembly (40). The valve seat assembly (10) comprises a first valve seat component (101) and a second valve seat component (102); the first valve seat component (101) comprises a side wall portion (1011) and a top wall portion (1012); the top wall portion (1012) extends from the side wall portion (1011) towards the center of the electric valve, and the side wall portion (1011) is fixedly connected to the second valve seat component (102); the top wall portion (1012) comprises a matching hole portion (1013); the matching hole portion (1013) runs through the top wall portion (1012); the nut assembly (40) comprises a nut body portion (401); the nut body portion (401) comprises an outer edge section; the outer edge section penetrates through the matching hole portion (1013), and the outer edge section matches the matching hole portion (1013); the nut assembly (40) is fixedly connected to the top wall portion (1012). The outer edge section of the electric valve penetrates through the matching hole portion, the outer edge section matches the matching hole portion, and when assembling the nut assembly and the valve seat assembly, the matching hole portion can provide a certain guide effect for the outer edge section of the nut assembly, and the coaxiality of the valve seat assembly and the nut assembly is good.
