詳細介紹

電動法蘭截止閥是一種比較新型的閘閥類別,它有著自身結構所*的一些*性,如開關無摩擦,密封不易磨損,啟閉力矩小。

電動法蘭截止閥產(chǎn)品優(yōu)點:
  1. 流體阻力小,其阻力系數(shù)與同長度的管段相等。
        2. 結構簡單、體積小、重量輕。
  3. 緊密可靠,目前閘閥的密封面材料廣泛使用塑料、密封性好,在真空系統(tǒng)中也已廣泛使用。
  4. 操作方便,開閉迅速,從全開到全關只要旋轉90°,便于遠距離的控制。
  5. 維修方便,閘閥結構簡單,密封圈一般都是活動的,拆卸更換都比較方便。
  6. 在全開或全閉時,球體和閥座的密封面與介質(zhì)隔離,介質(zhì)通過時,不會引起閥門密封面的侵蝕。
  7. 適用范圍廣,通徑從小到幾毫米,大到幾米,從高真空至高壓力都可應用。
工作原理
  電動截止閥,美標閘閥的工作原理是靠旋轉閥戀來使閥門暢通或閉塞。閘閥開關輕便,體積小,可以做成很大口徑,密封可靠,結構 簡單,維修方便,密封面與球面常在閉合狀態(tài),不易被介質(zhì)沖蝕,在各行業(yè)得到廣泛的應用。
電動截止閥在管路中主要用來做切斷、分配和改變介質(zhì)的流動方向。
電動法蘭截止閥廣泛適用于石油化工、城市給排水等要求嚴格切斷的工況。
