Three eccentric metal hard seal butterfly valve
Butterfly valve has been widely used in many fields, such as petroleum, chemical, metallurgy, water and electricity, as a part to realize the on-off and flow control of pipeline system. In the known butterfly valve technology, the sealing form of sealing structure, sealing materials for rubber, ptfe and so on. Due to the limitation of structure characteristics, it is not suitable for high temperature, high pressure, corrosion resistance, wear resistance and other industries. There is a more advanced butterfly valve is three eccentric metal hard seal butterfly valve, valve body and valve seat are joined component, valve seat sealing surface layer surfacing welding temperature, corrosion resistant alloy material. Multi-layer soft stack sealing ring fixed on the valve plate, this butterfly valve co***red with the traditional butterfly valve has high temperature resistance, light operation, opening and closing without friction, closed with the torque of the transmission mechanism to compensate for the sealing, improve the sealing performance of the butterfly valve and prolong the advantages of service life.
