At present, corrosion resistant ball valve, hard seal butterfly valve used to achieve piping system as an on-off and flow control components, has been used in many fields of petroleum, chemical, metallurgy, water and electricity are very widely used. In the butterfly valve has been publicly known technology, the seal forms a sealed structure, and sealing materials for rubber, PTFE and so. As the structure of the restrictions, not suited to high temperature, high pressure and corrosion resistance, wear and other industries. Present a more advanced three eccentric butterfly valve is a metal hard seal butterfly valve, valve and seat components for the piece, the valve seat sealing surface layer welding temperature, corrosion resistant alloy material. Stacked multi-layer soft sealing ring fixed in the valve plate, this butterfly valve compared with the conventional high temperature, easy operation, open and close without friction, closed with the transmission of the torque to compensate for increased seal, to improve a butterfly valve sealing performance and durability advantages. Now on the market are used in high temperature valve place more widely, is more and more widely.
