Butterfly valve refers to a valve whose closing part (disc or butterfly plate) is a disc, which rotates around the valve shaft to open and close. It is mainly used for cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The butterfly valve is usually less than 90° from fully open to fully closed. The butterfly valve and butterfly rod have no self-locking ability. In order to position the butterfly plate, a worm gear reducer should be installed on the valve rod. The use of worm gear reducer can not only make the butterfly plate have self-locking ability, make the butterfly plate stop at any position, but also improve the operating performance of the valve.
The characteristics of the industrial special butterfly valve are high temperature resistance, high applicable pressure range, large nominal diameter of the valve, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of a metal ring instead of a rubber ring.
