style="text-indent:25px">刀閘閥在流阻方面與截止閥的區(qū)別：刀閘閥在全開時整個流道直通，此時介質(zhì)的運行的壓力損失小，與截止閥相比較，他的主要優(yōu)點是流體流動阻力小，普通刀閘閥的流動阻力系數(shù)約為0.08~0.12，而普通截止閥的阻力系數(shù)約為3.5~4.5.開啟關(guān)閉力小。刀閘閥通常適用于不需要經(jīng)常啟閉而且保持閘板全開或全閉的工況，不適合調(diào)節(jié)、節(jié)流使用。而截止閥在整個行程中的流阻都很大，不平衡力大，所需的驅(qū)動力或力矩也相應(yīng)地要大很多。但他很適合用作流體的調(diào)節(jié)、節(jié)流。對于高速流動的介質(zhì)，閘板在局部開始狀況下，可以硬氣閥門的振動而振動，又可能損傷閘板和閥座的密封面，而節(jié)流，會使閘板遭受介質(zhì)的沖蝕。刀閘閥對有效密封性能要求的，密封試驗的泄漏按1×mm/s計算。</p><div
