Butterfly valves are also called flip valves. Switching control for low pressure piping media is a valve that opens and closes revolving around the valve shaft. And valves will use to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling in the pipeline. Butterfly valve is a disc shape butterfly plate rotating around its own axis in the valve, to open and close or adjust the purpose.
What are the characteristics of butterfly valves?
1. Butterfly valve has the characteristics of simple structure, small size, light weight, small material consumption, small installation size, fast switch, 90 reciprocating rotation, small driving torque and so on. So cut, connect and adjust the medium in the pipeline, with good fluid control characteristics and sealing performance.
2, Butterfly valve can carry mud, less liquid in the pipeline mouth. Good sealing can be achieved at low pressure. Good regulation performance.
3. Butterfly version streamlined design, fluid resistance loss is small. And it is energy-saving product.
4. Because the valve adopts through rod structure, after adjustment treatment, comprehensive mechanical properties are good, corrosion resistance, abrasion resistance. After the butterfly valve is close, the valve only rotates without lifting. The filling of the valve is not easy to break and the sealing is reliable. Fixed to disc conical pins, protruding ends are design to prevent valve collapse if the valve breaks unexpectedly where it is attach to the disc.
5, Connection methods are flange connection, wafer connection, and Lug wafer connection.
