The role of the butterfly valve

The previous article we have mentioned that what is butterfly valve,and the difference between the gate valve.This time i will introduce the role of butterfly valve.
It mainly paly a role in the pipeline cut off and throttling. Butterfly valve opening and closing pieces is a disc-shaped disc, the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing or regulation. The butterfly valve fully open to the whole is usually less than 90 °, the butterfly valve and the butterfly itself does not have self-locking ability, in order to disc positioning, need to install a worm reducer on the stem. The use of worm reducer, not only can make the disc self-locking have the ability to stop the butterfly plate in any position, but also can improve valve performance.
