Product Description
Welding butterfly valves are divided into cast steel welding butterfly valves, stainless steel welding butterfly valves, and chromium molybdenum steel welding butterfly valves.
Due to the limitations of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.
At present, fluorine lined butterfly valves and rubber lined butterfly valves, as components used to achieve on-off and flow control in pipeline systems, have been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower, and so on. In the well-known butterfly valve technology, the sealing form mostly adopts a sealing structure, and the sealing materials are rubber, PTFE, etc.
Due to the limitations of structural characteristics, it is not suitable for industries such as high temperature resistance, high pressure resistance, corrosion resistance, and wear resistance.
A relatively advanced butterfly valve is a triple eccentric metal hard seal butterfly valve, with the valve body and valve seat as interconnected components. The sealing surface of the valve seat is welded with heat-resistant and corrosion-resistant alloy materials.
The multi-layer soft stacked sealing ring is fixed on the valve plate. Compared with traditional butterfly valves, this type of butterfly valve has the advantages of high temperature resistance, easy operation, no friction when opening and closing, and compensates for sealing with the increase of torque of the transmission mechanism when closing, improving the sealing performance of the butterfly valve and extending its service life.
