Abstract

The invention discloses an electric valve, which includes a driving mechanism, a transmission assembly, a valve body assembly and a valve core. The driving mechanism includes a rotor assembly, a casing and a connecting seat. One end of the opening of the casing is fixedly connected with the connecting seat, and a casing is formed. cavity, the rotor assembly is accommodated in the sleeve cavity, the transmission assembly includes a first transmission mechanism, the first transmission mechanism includes a sun gear assembly, a fixed ring gear and at least one planetary gear assembly, at least one planetary gear assembly includes an output stage planetary gear assembly, The sun gear assembly is fixed to the rotor assembly, the fixed ring gear is fixed to the connecting seat, and the fixed ring gear is at least partly located in the rotor assembly; the output stage planetary gear assembly includes a planetary gear, a first mounting plate and a second mounting plate, and the planetary gear is arranged at the Between the first mounting plate and the second mounting plate, the first mounting plate can directly or indirectly drive the action of the valve core. The internal space of the rotor assembly is fully utilized, and part of the structure of the transmission assembly can be relatively compact, so that the volume of the electric valve is relatively small.

Description

【Technical field】 [0001] The invention relates to the technical field of fluid control, in particular to an electric valve. 【Background technique】 [0002] Electric valves are generally used for switching or on-off of fluids. At present, electric valves generally include driving mechanisms, transmission components and valve body parts, etc. The driving mechanism drives the valve core in the valve body to rotate through the transmission components to achieve fluid switching or on-off. . The transmission assembly is provided with a fixed-axis gear reduction mechanism, wherein the fixed-axis gear set is used to amplify the output torque of the motor. However, the fixed-axis gear set occupies a large space, so that the volume of the electric valve is also large. [Content of the invention] [0003] In order to solve the shortcomings of the above electric valve, the present invention provides an electric valve, which includes a drive mechanism, a transmission assembly, a valve...
