Abstract:
An electric valve (500), comprising a transmission mechanism (3), a valve core (6), and a valve body assembly (5). The valve body assembly is provided with a valve body cavity (51), the valve core is located in the valve body cavity, and the transmission mechanism is transmissionally connected to the valve core. The electric valve further comprises a connecting seat (9), which is fixedly connected to the valve body assembly, and the transmission mechanism comprises an output shaft (363); the electric valve further comprises a limiting frame (83), which is located on the radial outer circumference of the output shaft and is fixedly connected to the output shaft, the limiting frame being located on a side of the connecting seat relatively close to the valve core, and the limiting frame and the connecting seat being arranged opposite to each other and having a preset gap. The described structure of the electric valve is beneficial to reducing friction loss of a transmission mechanism, improving the service life of the transmission mechanism, and further improving the service life of an electric valve.
