Abstract

The invention relates to the related technical field of valves, and discloses an electric wafer type butterfly valve which comprises a valve body, a valve plate is movably installed on the inner wall of the valve body, a valve rod is fixedly installed in the middle of the valve plate, the valve rod penetrates through the valve body and is located on the outer side of the valve body, and an adjusting column is fixedly installed on the outer side of the valve body; the inner wall of the adjusting column and the valve rod are movably installed, an adjusting block is movably installed on the inner wall of the adjusting column and achieves rotation of the valve rod, a driving lead screw is fixedly installed at the top end of the adjusting block and is in threaded connection with the top end of the adjusting column, and a driving motor fixed through a telescopic rod is arranged at the top of the adjusting column; and an output shaft of the driving motor and the driving screw rod are fixedly mounted. The sealing bag is arranged on the outer side of the valve plate, so that in the process of adjusting opening and closing of the valve plate through the driving motor, the adjusting block can be pushed to enable media in the sealing bag to be increased and expanded to form sealing, and the purpose of self-adaptive sealing of the media is achieved.

Description

technical field [0001] The invention relates to the technical field related to valves, in particular to an electric wafer butterfly valve. Background technique [0002] With the development of electric valves, many well-known valve companies at home and abroad produce electric valves. Electric wafer butterfly valves are important execution units in the field of industrial automation control systems. It belongs to a variety of electric valves and electric regulating valves. [0003] The opening and closing of the butterfly valve is the function of directly controlling the rotation of the valve shaft through the driving device to drive the movement of the butterfly plate to realize the opening and closing function. In the process of opening and closing the butterfly valve, the driving device directly drives the movement of the butterfly plate to open and close the butterfly valve. During the opening and closing process of the valve, the outer seal will repeatedly slide and ru...
