功能
過壓和失壓保護(hù)
抗高沖擊和抗振——OSE?型含有一個二級跳閘機(jī)構(gòu)，大大減少了由于振動或入口壓力振動引起其他切斷閥產(chǎn)生的不必要跳閘的情況。
高精度——維持高達(dá)?±1%?的精度，無論入口壓力、流率以及快速切斷裝置的尺寸如何。
易于在線維護(hù)——頂裝式設(shè)計減少了維護(hù)時間和人力需求，無需將閥體從管線上拆下即可檢查和更換零件。
水密?——OSE?型水密性最高可達(dá)?10?ft?/?3.0?m。
完全切斷——閉合后，快速切斷閥保持閉合，直至系統(tǒng)關(guān)閉，手動重置閥門。?閥塞密封上有一個?O?型圈，保證切斷密閉性。
遠(yuǎn)程報警功能——提供一個限制開關(guān)，可檢測到?OSE?快速切斷閥跳閘的情況。
