VALVE PACKING SHIELD FOR USE IN HYDROCARBON OPERATIONS |
摘要 |
A valve assembly includes a valve body defining a flow passage and a body cavity perpendicular to the flow passage. A bonnet is secured to the valve body. A valve member is moveable between an open position and a closed position, the valve member blocking the flow passage in the closed position, and allowing flow through the flow passage in the open position. A valve stem is coupled to the valve member. A debris barrier circumscribes the valve stem. The debris barrier comprises a first disk shaped member with a central opening through which the valve stem is inserted, and notches that extend radially from the central opening to define petals with ends that abut the valve stem. |
