詳細(xì)介紹

電動(dòng)法蘭截止閥廣泛適用于石油化工,火力發(fā)電廠等油品、水蒸汽管路上作接通或截?cái)喙苈分薪橘|(zhì)的啟閉裝置。

 

電動(dòng)截止閥的特點(diǎn)
  
  1.流體阻力小,其阻力系數(shù)與同長度的管段相等。
  
  2.結(jié)構(gòu)簡單、體積小、重量輕。電動(dòng)截止閥
  
  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(guān)只要旋轉(zhuǎn)90°,便于遠(yuǎn)距離的控制。
  
  5.維修方便,閘閥結(jié)構(gòu)簡單,密封圈一般都是活動(dòng)的,拆卸更換都比較方便。
  
  6.在全開或全閉時(shí),球體和閥座的密封面與介質(zhì)隔離,介質(zhì)通過時(shí),不會(huì)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(yīng)用。
