style="text-indent:25px">真空閥門的裝置前仔細閱讀說明書：堵截有關(guān)電源并由專業(yè)技術(shù)人員進行裝置。水流方向同閥體上的箭頭方向相同。閥體須坐落盤管接水盤上方，以確保呈現(xiàn)滴水時落入接水盤中。閥體及驅(qū)動器裝置于垂直方向±60℃范圍內(nèi)，其上方應(yīng)至少有30mm空間用于拆裝。與周圍管道、設(shè)備、建筑物保持足夠的維修操作空間，裝置在維修人員經(jīng)過檢修孔能觸及到的地方。閥體裝置完畢并與管路經(jīng)過試壓后才可裝置驅(qū)動器。若驅(qū)動器已經(jīng)裝到閥體上，在裝置調(diào)試過程中絕不能對驅(qū)動器施力，否則會損壞驅(qū)動器。裝置完畢并查看正確無誤后，通電調(diào)試。至少應(yīng)觀察驅(qū)動器的三個完整運行周期，確定所有部件正確停止。經(jīng)過無水調(diào)試合格后，再進行通水測試。體系上下水的壓差嚴厲控制在0.15MPa以內(nèi)，以確保電動調(diào)節(jié)閥對水流開關(guān)的有效性。</p><p style="text-indent:25px">真空閥門如何維護?明確目的對壓力維護的目的，在于延長真空閥門壽命和保證正常運行。對于經(jīng)常與閥桿螺母摩擦的閥桿螺紋，可以涂一點黃干油、二硫化鉬或石墨粉，目的是潤滑減少摩擦阻力。流水不腐，戶樞不蠹。不僅經(jīng)常轉(zhuǎn)動的自力式壓力調(diào)節(jié)閥要有潤滑措施。對于不經(jīng)常啟閉的自力式壓力調(diào)節(jié)閥，也要定期轉(zhuǎn)動手輪，對閥桿螺紋添加潤滑劑，以防生銹。真空閥門，要對閥桿加保護套，目的是防止雨、雪、塵土等進入真空閥門內(nèi)部導致銹污。如真空閥門系機械待動，要按時對變速箱添加潤滑油。要經(jīng)常保持真空閥門的清潔。氣動高真空擋板閥是一款適用的工作介質(zhì)為空氣及非腐蝕性氣性的擋板閥。</p><div
