The butterfly plate of the soft sealing butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc shaped butterfly plate rotates around the axis, and the rotation angle is 0 degrees ~90 degrees. When the rotation is 90 degrees, the valve is fully opened. The characteristics of the new type high life stainless steel butterfly valve and the problems existing in the use of butterfly valves should be installed horizontally in pipelines. Soft seal butterfly valve can be divided into flange type soft seal butterfly valve, clip type soft seal butterfly valve and welding type soft sealing butterfly valve according to connection mode.
Product introduction 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.
