Abstract

The invention discloses a butterfly valve flow regulating device comprising a butterfly valve pipe. A seal rubber ring is attached to the inner wall of the butterfly valve pipe. A plurality of clamping devices are attached to the seal rubber ring in a surrounding mode. A bolt is connected in the middle of each clamping device vertically rotationally. A second nut is installed on the inner wall ofthe butterfly valve pipe, and the bolt is in threaded connection with the second nut. An annular stop piece is installed in the butterfly valve pipe. A round stop piece is installed in the hollow position of the annular stop piece. A first rotary shaft is fixedly connected to the left end of the annular stop piece. The two ends of the butterfly valve pipe are each fixedly connected with a valve body. The butterfly valve flow regulating device is stable in structure and convenient to operate, the designs of the two stop pieces are matched mutually so that water flow can be controlled more accurately, regulating use can be convenient for a worker, and the butterfly valve flow regulating device is worth popularization.

Description

technical field [0001] The invention relates to the technical field of butterfly valves, in particular to a butterfly valve flow regulating device. Background technique [0002] It is undeniable that butterfly valves have become one of the most widely used valves at present. Generally, a butterfly valve includes a valve body, a valve seat, a valve stem, and a valve disc. That is, the valve seat is fixed in the inner cavity of the valve, the valve disc is located in the inner cavity of the valve seat, and after the valve disc rotates, its edge and the valve seat are sealed or opened, and the valve rod is used to drive the valve disc to perform After rotating, the upper part of the valve stem passes through the upper part of the valve body and is connected to a rotating device such as a handle or an actuator. However, the working environment of butterfly valves is mostly harsh, such as dusty, high temperature, high pressure of the circulating medium, corrosive medium, etc., ...
