Abstract

The invention discloses an electric blind plate valve, which includes a valve body, a valve plate, a driving device and a transmission rod. , and the end of the central shaft away from the support rod is fixedly connected with a gear. In the present invention, a valve plate and a support rod are provided inside the valve body, a central shaft is provided on the support rod, a stirring plate is provided outside the central shaft, a gear is provided at one end of the central shaft, and a groove is provided on the valve plate. A rack is set on the groove. The advantage of this design is that when the valve plate moves, the rack moves synchronously. The rack can drive the gear to rotate, and then drive the central shaft and the stirring plate to rotate. The stirring plate can stir and break the inner wall of the valve. The remaining material, at the same time, the rotating stirring plate also plays the role of conveying material, transporting the stirred material away. This design makes it difficult for the material to remain on the inner wall of the valve body, so that the valve body is not easy to be blocked by viscous material.

Description

technical field [0001] The invention relates to the technical field of blind plate valves, in particular to electric blind plate valves. Background technique [0002] Blind valve is a manual, electric or gas, hydraulic gate valve that cuts off the gas medium, generally divided into electric blind valve, hydraulic blind valve, pneumatic blind valve, closed plug valve, electric open Blind valve. The blind plate valve includes a left valve body, a right valve body, a valve plate, a drive screw, a valve body clamping drive mechanism and a valve plate flip drive mechanism, and the valve plate is symmetrically hinged between the left valve body and the right valve body , the left valve body and the right valve body are arranged side by side at intervals, and the left valve body and the right valve body are provided with corresponding valve ports, and one side of the valve plate is provided with a blind plate that is sealingly adapted to the valve port. The other side of the plat...
