Products Description
The valve disc rotation center (i.e., valve axis center) of the triple eccentric butterfly valve forms an A offset with the valve disc sealing section, and forms an B offset with the valve body center; the valve body sealing surface centerline and the valve seat centerline (i.e., valve body centerline) form an angular offset of angle β. In order to overcome this contradiction of the double eccentric butterfly valve, the butterfly valve is eccentric for the third time. Its structural feature is that while the valve stem axis position of the double eccentric is eccentric, the conical axis of the butterfly disc sealing surface is deflected to the cylindrical axis of the body, that is, after the third eccentricity, the sealing section of the butterfly disc is no longer a true circle, but an ellipse, and the shape of its sealing surface is asymmetric, with one side tilted to the center line of the body and the other side parallel to the center line of the body.
