| description | To provide a drive mechanism for an air-operated valve that can switch between an open-closed state maintenance function and forced close.SOLUTION: A drive mechanism K1 for an air-operated valve B includes open-close state maintenance means d1, d2, 1, 2, 3, 4 for maintaining an open-close state of the air-operated valve B that is operated with operation air 10, in the event of a failure; and first closed state switching means d2 for switching the air-operated valve B to a closed state mode from an open-close state maintenance mode.SELECTED DRAWING: Figure 3
【課題】開閉状態維持機能と強制閉とを切り替え可能な空気作動弁の駆動機構を提供する。【解決手段】本発明の空気作動弁Ｂの駆動機構Ｋ１は、操作空気１０で作動する空気作動弁Ｂの開閉状態を異常発生時に維持する開閉状態維持手段ｄ１、ｄ２、１、２、３、４と、空気作動弁Ｂの開閉状態維持モードから閉状態モードに切替える第１閉状態切替手段ｄ２とを備えている。【選択図】図３ |
