Introduction to the characteristics of sanitary stainless steel butterfly valve products
The characteristics of sanitary stainless steel butterfly valve products are introduced. Sanitary stainless steel butterfly valve refers to a kind of valve whose blocking part (disc or butterfly plate) is a disc, which is twisted around the valve shaft to achieve opening and blocking. It is mainly used for cutting off and saving on the pipeline. . The stainless steel butterfly valve opening and closing part is a disc-shaped butterfly plate, which is twisted around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. The sanitary stainless steel butterfly valve is usually less than 90° from fully open to fully closed. The stainless steel butterfly valve and the butterfly stem have no self-locking ability. For the positioning of the butterfly plate, a worm gear reducer should be installed on the valve stem. The use of worm gear reducer can not only make the butterfly plate have self-locking ability, make the butterfly plate contain in the arbitrary position, but also improve the operating function of the valve. The industrial-specific stainless steel butterfly valve is characterized by high temperature resistance, and has a relatively large scale. The nominal diameter of the valve is large, the valve body is made of carbon steel, and the sealing ring of the valve plate uses a metal ring instead of a rubber ring. The large type high temperature sanitary stainless steel butterfly valve is made of steel plate welding, and is mainly used for flue gas ducts and gas pipes of high temperature media. The benefits of sanitary stainless steel butterfly valves are as follows: 1. It is convenient to open and close quickly, save labor, and has low fluid resistance, and can be operated frequently. 2. Simple structure, small size and light weight. 3. Mud can be transported, at least the backlog of liquid at the pipe mouth. 4. Under low pressure, excellent sealing can be achieved.
