結構特點及用途
1、電動偏心半球閥壓力損失?。喝_時水損為零,流道*暢通,且介質不會沉積在閥體中腔內。
2、耐顆粒磨損:V型開口的球冠與金屬閥座之間具有剪切作用,在關閉過程中,只在zui后一刻球冠才靠向閥座,不形成磨擦,且閥座耐磨的鎳合金制成,不易被沖刷磨損,因而適用于含纖維、微小固體顆粒、漿等。
3、適合高流速介質:直通流道,堅固的偏心一曲軸使之適合高流速且無振動。
4、壽命長:無易損部件,由于偏心作用,閥門啟閉時密封面間無磨擦,則使用壽命長。
5、維修方便:閥門維修時不需從管路上拆下,只要打開閥蓋即可進行維修
6、氣動偏心半球閥廣泛適用于水、污水、含微小固體顆粒、水、蒸汽、煤氣、天然氣、油品等。
