Functional use of product
Sanitary duck-billed butterfly valve (English: butterfly valve) refers to the closing part (valve disc or butterfly plate) is a disk, revolving around the valve shaft to achieve the opening and closing of a valve. It is mainly used for cutting and throttling in the pipeline. The opening and closing part of the sanitary duck-beak 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 adjusting. The sanitary duck-billed butterfly valve is usually less than 90° when it is fully opened to fully closed. The sanitary duck-billed butterfly valve and the butterfly rod themselves have no self-locking ability. In order to position the butterfly plate, a turbine reducer should be installed on the valve stem. The use of wheel reducer can not only make the butterfly plate self-locking ability, so that the butterfly plate stops in any position, but also improve the operating performance of the valve. The characteristics of industrial special butterfly valve can withstand high temperature, the applicable pressure range is also high, the valve nominal pass is large, the valve body is made of carbon steel, and the sealing ring of the valve plate is made of metal ring instead of rubber ring. Flow direction: one-way
