日常電動閥門維護保養

2018.04.08
1、電動閥門應存干燥通風的室內,通路兩端須堵塞。
2、長期存放的電動閥門應定期檢查,并在加工面上涂防銹油。
3、安裝后,應定期進行檢查,主要檢查項目:
(1)密封面磨損情況。
(2)閥桿和閥桿螺母的梯形螺紋磨損情況。
(3)填料是否過時失效,如有損壞應及時更換。
(4)電動閥門檢修裝配后,應進行密封性能試驗。
運行中的電動閥門,各種閥件應齊全、完好。法蘭螺紋和支架上的螺栓不可缺少,螺紋應完好無損,不允許有松動現象。手輪上的緊固螺母,如發現松動應及時擰緊,以免磨損連接處或丟失手輪和銘牌。手輪如有丟失,不允許用活扳手代替,應及時配齊。填料壓蓋不允許歪斜或無預緊間隙。對容易受到雨雪、灰塵、風沙等污物沾染的環境中的電動閥門,其閥桿要安裝保護罩。電動閥門上的標尺應保持完整、準確、清晰。電動閥門的鉛封、蓋帽、氣動附件等應齊全完好。保溫夾套應無凹陷、裂紋。
不允許在運行中的電動閥門上敲打、站人或支承重物;特別是非金屬電動閥門和鑄鐵電動閥門,更要禁止。
