2.Q941F-16C DN50

主要用于截斷或接通管路中的介質,亦可用于流體的調節與控制,它與其它閥類相比,具有以下一些優點。
1,流體阻力小,球閥是所有閥類中流體阻力zui小的一種,即使是縮徑球閥,其流體阻力也相當小。
2,止推軸承減小閥桿摩擦力矩,可使閥桿長期操作平衡靈活。
3,閥座密封性能好,采用聚四氟乙烯等材料制成的密封圈,結構易于密封,而且球閥的閥封能力隨著介質壓力的增設而增大。
4,閥桿密封可靠,由于閥桿只作旋轉運動而不做升降運動,閥桿的填料密封不易破壞,且密封能力隨著介質的壓力增設而增大。
5,由于聚四氟乙烯等材料具有良好的自潤滑性,與球體的摩擦損失小,幫球閥的使用壽命長。
6,下裝式閥桿和閥桿頭部凸階防止閥桿噴出,如火災造成閥桿密封破壞,凸階與閥體間還可形成金屬接觸,確保閥桿密封。
Q941F/PPL型不銹鋼電動球閥是一種轉角為90°的旋轉類閥門,密封性能優良,流量系數大,流阻系數小,結構簡單,使用壽命長,便于維修。配用電缸式執行機構。產品廣泛應用于化工,石油,輕紡,電力,食品制藥,制冷,造紙行業的系統控制。
