BUTTERFLY VALVE |
摘要 |
Fig.l A butterfly valve has its seat formed on a detachable ring which is normal to the axis of the valve body. Both the seat and a co-operating seal on the valve disc have frusto-conical contact surfaces such that with the valve closed these surfaces are on a common cone with an axis inclined to body axis. The disc rotates about an axis offset beyond the larger ends of the contact surfaces and also offset to one side of both the body and cone axes. Operation of the valve and its maintenance are thereby improved. |
