Working principle and characteristics of butterfly valve

The butterfly valve is based on the rotary valve to open and close the valve, driving the disc plate to rotate. In the cylindrical channel of the butterfly body, the disc rotates around the axis, mainly rotating the plate 90 degrees. When the flow control panel reaches 90 degrees, the valve is fully opened, and the medium flow can be adjusted by changing the angle of the valve. Usually installed in the diameter direction of the pipe. The butterfly valve and the stem itself have no locking function. In order to effectively control the flow, a worm gear reducer is required. The butterfly valve with worm gear reducer can not only automatically lock the butterfly valve, but also change the working performance of the butterfly valve and adjust the medium flow more accurately.
