style="text-indent:25px">氣動閥門安裝后，應(yīng)定期進(jìn)行檢查，主要檢查項目：密封面磨損情況。閥桿和閥桿螺母的梯形螺紋磨損情況。填料是否過時失效，如有損壞應(yīng)及時更換。閥門檢修裝配后，應(yīng)進(jìn)行密封性能試驗。氣動閥門使用維護(hù)注意事項：使用維護(hù)的目的，在于延長閥門壽命和保證啟閉可靠。閥桿螺紋，經(jīng)常與閥桿螺母摩擦，要涂一點(diǎn)黃干油、二硫化鉬或石墨粉，起潤滑作用。不經(jīng)常啟閉的閥門，也要定期轉(zhuǎn)動手輪，對閥桿螺紋添加潤滑劑，以防咬住。室外閥門，要對閥桿加保護(hù)套，以防雨、雪、塵土銹污。如閥門系機(jī)械待動，要按時對變速箱添加潤滑油。</p><p
