發現電動球閥觸點自動跳怎么解決?

人氣:1發表時間:2019/9/10 2:11:23

電動球閥觸點自動跳的原因有哪些


       電動球閥它具有旋轉90度的動作,旋塞體為球體,有圓形通孔或通道通過其軸線。電動球閥的主要特點是本身結構緊湊,密封可靠,結構簡單,維修方便,密封面與球面常在閉合狀態,不易被介質沖蝕,易于操作和維修。球閥在管路中主要用來做 電動球閥切斷、分配和改變介質的流動方向,它只需要用旋轉90度的操作和很小的轉動力矩就能關閉嚴密。


      球閥最適宜做開關、切斷閥使用,但近來的發展已將球閥設計成使它具有節流和控制流量之用,如V型球閥。適用于水、溶劑、酸和天然氣等一般工作介質,而且還適用于工作條件惡劣的介質,如氧氣、過氧化氫、甲烷和乙烯等,在各行業得到廣泛的應用。球閥閥體可以是整體的,也可以是組合式的。


電動球閥特點


      電動球閥構造簡略,只由少數幾個零件組成,資料耗用??;體積小、重量輕、安裝尺寸小,驅動力矩小, 壓力調節閥,操作簡便、敏捷,只需旋轉90°即可快速啟閉;并且還同時具有良好的流量調節功效和封閉密封特性,在大中口徑、中低壓力的應用范疇,電動球閥是主導的閥門情勢。電動球閥處于完整開啟地位時,蝶板厚度是介質流經閥體時唯一的阻力,因此通過該閥門所發生的壓力降很小,故具有較好的流量把持特征。
