Butterfly valve features and methods of use
A butterfly valve is a valve in which the closing member (valve or disc) is a disc that rotates around the valve shaft to open and close and is used primarily for pipe cutting and throttling. The butterfly valve opening and closing member is a disc disc that rotates around its own axis in the valve body for the purpose of opening and closing or adjusting. From fully open to fully closed, the butterfly valve is usually less than 90 °. Butterfly valves and stems do not have self - locking capability. A worm gear reducer is added to the stem to position the disc. The use of worm gear reducer not only makes the disc self-locking, but also can stop the disc at any position and improve the operating performance of the valve.
Industrial special axial check valve is characterized by high temperature resistance, suitable pressure range is also high, the valve nominal diameter is large, the valve body is made of carbon steel, the valve plate seal ring is made of metal ring rather than rubber ring. Large high temperature butterfly valve is manufactured by welding steel plate, which is mainly used for flue and gas pipeline of high temperature medium.
