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(yùn)行的壓力損失小，與截止閥相比較，他的主要優(yōu)點(diǎn)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。</p><p style="text-indent:25px">電動式刀閘閥的使用注意事項(xiàng)及其特點(diǎn):電動式刀閘閥的啟閉件是閘板，閘板的運(yùn)動方向與流體方向相垂直，刀型閘閥只能作全開和全關(guān),不能作調(diào)節(jié)和節(jié)流。電動式刀閘閥關(guān)閉時,密封面可以只依靠介質(zhì)壓力來密封,即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封,這就是自密封。電動式刀閘閥的安裝流程：1.安裝前須檢查閥門腔內(nèi)和密封面等部位，不允許有污物或砂粒附著；2.各連接部位螺栓,要求均勻擰緊；3.檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活；4.用戶在安裝閥門前，必須校對閥門型號，連接尺寸及注意介質(zhì)流向，保證與閥門要求一致性；5.用戶在安裝閥門時，必須預(yù)留閥門驅(qū)動的必要空間；6.驅(qū)動裝置的接線須按線路圖進(jìn)行；7.刀閘閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。手動刀型閘閥只能作全開和全關(guān),不能作調(diào)節(jié)和節(jié)流！</p><div
