In order to solve the problem of concentric butterfly valve butterfly plate and valve seat extrusion, thus produced a single eccentric butterfly valve, the structural characteristics of the valve stem axis deviated from the centre of the butterfly plate, so that the upper and lower ends of the butterfly plate is no longer become the rotary axis, dispersed, to alleviate the upper and lower ends of the butterfly plate and the valve seat of the excessive extrusion.
