Document Type and Number:
WIPO Patent Application WO/2021/169037
Kind Code:
A1
Abstract:
An electric valve, comprising a valve body, a rotor component (20), a transmission member (22), and a gear reducer mechanism. The rotor component (20) comprises a rotor shaft (21), the transmission member (22) is fixedly connected to a transmission end portion of the rotor shaft (21), and the rotor shaft (21) drives, by means of the transmission member (22), an input gear (31) of the gear reducer mechanism to rotate. The electric valve further comprises an elastic member (23), and the transmission member (22) is in elastic contact with the input gear (31) by means of the elastic member (23) so as to achieve transmission of power. The transmission member of the electric valve is in the elastic contact with the input gear by means of the elastic member so as to achieve the transmission of power, so that transmission noise is greatly reduced, and transmission noise pollution of the electric valve is reduced; moreover, it is favorable for the electric valve to be used in the environment having relatively harsh noise requirements, thereby improving flexible use of the electric valve.
