As a component used to cut off and control the flow of the pipeline system, the Soft Sealed Butterfly Valve has been widely used in many fields, such as oil, chemical, metallurgical and hydroelectric fields. In the known butterfly valve technology, the sealing form is mostly made of sealing structure, and the sealing material is rubber, polytetrafluoroethylene and so on. Due to structural limitations, it is not suitable for such industries as high temperature resistance, high pressure, corrosion resistance and wear resistance. A more advanced butterfly valve is three eccentric metal hard seal butterfly valve, the valve body and the seat are connected components, and the sealing surface layer of the seat is surfacing with temperature resistant and corrosion resistant alloy materials. The multi layer soft superimposed seal is fixed on the valve plate. This butterfly valve has the high temperature resistance compared with the traditional butterfly valve, the operation is light and open and closed without friction. The valve is compensated and sealed with the torque of the transmission mechanism in the closed, and improves the sealing performance of the butterfly valve and the advantages of prolonging the service life.
