Fluorine-lined butterfly valve

The butterfly plate of the fluorine-lined butterfly valve is installed 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 rotated to 90°, the valve is fully open.

Fluorine-lined butterfly valve, as a kind of component used to realize the on-off and flow control of pipeline system, has been widely used in many fields such as petroleum, chemical, metallurgy, hydropower and so on. 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, is light in operation, and has no friction in opening and closing. When closing, the seal is compensated with the increase of the torque of the transmission mechanism, and the butterfly valve is improved. The sealing performance and the advantage of extending the service life. This type of valve should generally be installed horizontally in the pipeline.
