Abstract:

An electric valve, comprising a valve body component (2), a valve core (4), a valve core base (23), and a first sealing member (24). The valve body component (2) comprises an accommodating portion (214), and the accommodating portion (214) forms an accommodating cavity (215). The first sealing member (24) comprises a first protruding portion (242), a second protruding portion (243), and a main body portion (241); the main body portion (241) is located between the first protruding portion (242) and the second protruding portion (243). The valve core base (23) comprises a first surface (2321), a second surface (2322), and a third surface (2314), wherein the first surface (2321) and the third surface (2314) extend in the radial direction of the valve core base (23); at least a part of the valve core base (23) is located in the accommodating cavity (215), and the first sealing member (24) is located in the accommodating cavity (215). Along the radial direction of the accommodating portion (214), the first protruding portion (242) abuts against the second surface (2322), and the second protruding portion (243) abuts against the accommodating portion (214); and along the axial direction of the accommodating portion (214), the main body portion (241) is axially pressed between the first surface (2321) and the side wall (221) of the valve body component (2), and the outer surface of a part of the valve core (4) is tightly attached to at least a part of the third surface (2314), thereby facilitating improving the sealing performance of the electric valve.
