发明名称 Valve stem lock
摘要 A valve stem lock for valves having an exposed valve stem. The lock is comprised of a pair of hinged sections movable from an open position to a closed position to lock about a valve stem. The two sections are provided with a base having slots which are adapted to bear against exposed bolts or the yoke of the valve stem so that rotation of the valve stem upon removal of a part such as a bushing nut or the like is prevented. The two hinged sections are adapted to be locked together in the closed position.
