Soft sealing butterfly valve:
The disc of the soft sealing butterfly valve is mounted in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully open.
The characteristics of the new high-life stainless steel butterfly valve and the problems in the use of the butterfly valve At present, the soft-sealed butterfly valve has been used in many fields such as petroleum, chemical, metallurgy, hydropower, etc. as a component for implementing the on-off and flow control of the pipeline system. It is extremely widely used. In the well-known butterfly valve technology, the sealing form is mostly sealed, and the sealing material is rubber, polytetrafluoroethylene or the like. Due to structural limitations, it is not suitable for industries such as high temperature resistance, high pressure, corrosion resistance and wear resistance. A relatively advanced butterfly valve is a three-eccentric metal hard sealing butterfly valve. The valve body and the valve seat are connected members, and the sealing surface layer of the valve seat is welded with a temperature-resistant and corrosion-resistant alloy material. The multi-layer soft stack sealing ring is fixed on the valve plate. Compared with the traditional butterfly valve, the butterfly valve has high temperature resistance, light operation, no friction in opening and closing, and the seal is compensated with the increase of the torque of the transmission mechanism when closing, and the butterfly valve is improved. The sealing performance and the advantage of extending the service life.
