An electric valve

Abstract

An electric valve includes a valve body, which includes a valve seat assembly and a valve core rotor assembly. The valve core rotor assembly includes a valve shaft assembly, a valve core, first / second elastic members, and an abutment member. The valve shaft assembly includes a valve shaft abutment portion, and a second elastic member is supported on the valve shaft abutment portion. The valve core includes first / second valve core abutment portions, and the valve core passes through the valve shaft assembly. The first valve core abutment portion can abut against the second elastic member. The first elastic member abuts against the valve shaft assembly. The abutment member includes a first abutment portion, which abuts against the first elastic member. The abutment member also includes a second abutment portion, which can abut against the second valve core abutment portion. The abutment member further includes a third abutment portion, which can abut against the valve shaft assembly. When the third abutment portion abuts against the valve shaft assembly and the first valve core abutment portion abuts against the second elastic member, the second abutment portion and the second valve core abutment portion do not abut against each other, which can reduce the impact force of the valve core on the valve port at the moment of contact between the valve core and the valve port.
