Features of single eccentric sealing butterfly valve: 1. The structure is more complicated than the centerline sealing butterfly valve, and the cost is slightly higher;
The sealing principle of single eccentric sealing butterfly valve:1. Structural features: The center of rotation of the valve disc (the center of the valve shaft) is located on the centerline of the valve body, and forms an α dimension offset with the sealing section of the valve disc.
The sealing principle of the centerline butterfly valve is to ensure that the sealing surface has a suitable surface roughness when processing the valve disc, and the synthetic rubber valve seat forms a suitable surface roughness value of the sealing surface during molding.
