本發(fā)明涉及抽水蓄能設備的技術領域,尤其涉及一種閥門操作手柄鎖定裝置。本發(fā)明包括閥門和閥門操作軸,是由手柄支撐支架連接在閥門上,閥門操作軸鎖定套連接在閥門操作軸上;操作手柄和鎖定手柄依次設在鎖定桿上,鎖定桿的下端穿過手柄支撐支架與閥門操作軸鎖定套相接觸。本發(fā)明中鎖定閥門在設定開度時,可防止閥門開度發(fā)生非人為改變,影響機組正常運行,還可消除因閥門手柄抖動而產(chǎn)生的噪聲,減少閥門手柄抖動對閥門閥軸密封的危害,保證抽水蓄能機組工作的正常運行。本發(fā)明設計簡潔,操作方便,易損件通用,便于維護,不會對閥門操作軸的扭力強度產(chǎn)生不良影響,并具美觀和實用性于一體,為設備的優(yōu)化改造貢獻了力量。
