Vacuum butterfly valve operation principle introduction

Vacuum butterfly valve operation principle

The butterfly valve is a valve that drives the disc to roll and open according to the rotating valve stem. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis.

The first is to rotate the disc 90° for flow control. When the disc reaches 90°, the valve is fully open. Together, the disc can be modified to adjust the medium flow, generally in the diameter direction of the pipe.

The butterfly valve and the valve stem itself have no certainty. In order to use the worm gear reducer for useful conditioning and saving, the butterfly valve with the worm gear reducer not only makes the butterfly valve self-locking, but also can change the operating performance of the butterfly valve and the conditioning medium flow.
