WIPO Patent Application WO/2022/166782
Kind Code:
A1
Abstract:
An electric valve, comprising a valve body. The valve body comprises a valve seat component (10) and a valve core rotor assembly (20). The valve core rotor assembly (20) comprises a valve shaft assembly (201), a valve core (202), an elastic member (204), and an abutting component (206). The valve shaft assembly (201) comprises a valve shaft abutting part (20154); the valve core (202) comprises a first valve core abutting part (202b) and a second valve core abutting part (202c); the valve core (202) penetrates the valve shaft assembly (201); the first valve core abutting part (202b) can abut against the valve shaft abutting part (20154); the elastic member (204) abuts against the valve shaft assembly (201); the abutting component (206) comprises a first abutting part (206a), and the elastic member (204) abuts against the first abutting part (206a); the abutting component (206) comprises a second abutting part (206b), the valve core (202) comprises the second valve core abutting part (202c), and the second abutting part (206b) can abut against the second valve core abutting part (202c); and the abutting component (206) comprises a third abutting part (206c), and the third abutting part (206c) can abut against the valve shaft assembly (201). By means of the electric valve, the impact force of the valve core (202) on a valve port (10a) can be reduced when the valve core (202) comes into contact with the valve port (10a).
