The top connection valve handle of axle, props up the valve plate being arranged in the valve body between the upper valve shaft and lower valve shaft, the valve plate
Upper and lower end face is equipped with convex edge.
Further, the convex edge is integrally formed with the valve plate, and the height of its protrusion valve plate is 5 ＜ H ＜ 20mm,
Which mainly increases the interference area between valve plate and valve seat, so as to strengthen the sealing of valve body.
Further, the central axis of the valve plate are provided with the retaining bar for propping up the upper valve shaft and lower valve shaft.
Further, the two ends of the retaining bar are provided with fixing axle, and the fixing axle is against the upper valve shaft with respectively
At the axis hole that valve shaft is provided with.
Further, interior axle is additionally provided between the outer shaft and upper valve shaft, the interior axle is stuck in the interior of the outer shaft
On wall.
Further, sealing shroud is provided with the outside of the valve seat, its objective is further to increase valve plate in valve seat upper and lower side
Contact surface junction product between face, improves sealing.
Further, sealing ring is additionally provided between the outer shaft and upper valve shaft, the sealing ring is positioned close to described
Valve seat side, its objective is to reduce the gap between outer shaft and upper valve shaft, improves sealing.
The beneficial effects of the utility model are：Surface area of this utility model using increase valve plate upper and lower end face, so as to can
Effectively to increase the Interference contact area of valve plate and valve seat, so effectively can prevent the valve plate of center line soft sealing butterfly valve with
Valve seat contacts the leakage of end.
