Abstract
An electrically operated valve, comprising a valve body component, a drive component and a nut sleeve piece. The drive component comprises a magnetic rotor, a screw rod and a nut, the magnetic rotor being arranged in an inner cavity of a valve cover body, the screw rod being threadedly connected to the nut, the screw rod being incapable of movement in the axial direction with respect to a valve body. The nut sleeve piece comprises a first limiting portion which limits rotation of the nut in the circumferential direction, the cross-section of the first limiting portion being non-circular. A compact structure, which helps to reduce the size of the electrically operated valve.
