Three-eccentric structure of fluorine-lined butterfly valve

The fluorine-lined butterfly valve must use a hard seal to withstand high temperature, but the leakage is large; to have zero leakage, a soft seal must be used, but it is not resistant to high temperature. In order to overcome the contradiction of the double eccentric butterfly valve, the butterfly valve was eccentric for the third time. Its structural feature is that the conical axis of the disc sealing surface is deviated from the cylinder axis of the body while the position of the double eccentric valve stem is eccentric, that is, after the third eccentricity, the sealing section of the disc is not Then it is a true circle, but an ellipse, and the shape of its sealing surface is also asymmetrical, one side is inclined to the center line of the body, and the other side is parallel to the center line of the body.
