Abstract
In an electric valve provided by the present invention, a gear reduction mechanism comprises a first ring gear, a second ring gear as well as an upper planetary gear assembly and a lower planetary gear assembly arranged in the longitudinal direction of the electric valve; at least part of the first ring gear is located in an inner cavity of a rotor member; an input gear part of the rotor member meshes with planetary gears of the upper planetary gear assembly; and the lower planetary gear assembly is rotatably connected to a transmission rod. In this embodiment, at least part of the first ring gear is located in the inner cavity of the rotor member, thereby reducing the size of the electric valve.
