The first eccentricity is that the valve shaft is located behind the valve plate shaft, so that the seal is completely wrapped around the entire seat.
The second eccentricity is that the centerline of the valve shaft deviates from the actual pipeline and the centerline of the valve to avoid interference from the opening and closing of various valves.
The third eccentricity is the deviation of the valve seat cone axis and the center line of the valve stem, which eliminates the friction during the closing and opening process, and achieves a uniform compression seal around the entire valve seat.
The above is the introduction of the triple eccentric butterfly valve. The triple eccentric butterfly valve is a high-performance butterfly valve. It has been used in many fields and has even replaced gate valves, globe valves, ball valves and other products in some fields.
