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(shí)，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。</p><p style="text-indent:25px">刀閘閥使用過程中可能會出現(xiàn)的幾點(diǎn)疑問？什么直行程調(diào)節(jié)閥防堵性能差，角行程閥防堵性能好？直行程閥閥芯是垂直節(jié)流，而介質(zhì)是水平流進(jìn)流出，閥腔內(nèi)流道必然轉(zhuǎn)彎倒拐，使閥的流路變得相當(dāng)復(fù)雜(形狀如倒“S”型)。這樣，存在許多死區(qū)，為介質(zhì)的沉淀提供了空間，長此以往，造成堵塞。角行程閥節(jié)流的方向就是水平方向，介質(zhì)水平流進(jìn)，水平流出，容易把不干凈介質(zhì)帶走，同時(shí)流路簡單，介質(zhì)沉淀的空間也很少，所以角行程閥防堵性能好。為什么直行程調(diào)節(jié)閥閥桿較細(xì)？它涉及一個簡單的機(jī)械原理：滑動摩擦大、滾動摩擦小。直行程閥的閥桿上下運(yùn)動，填料稍壓緊一點(diǎn)，它就會把閥桿包得很緊，產(chǎn)生較大的回差。為此，閥桿設(shè)計(jì)得非常細(xì)小，填料又常用摩擦系數(shù)小的四氟填料，以便減少回差，但由此派出的問題是閥桿細(xì)，則易彎，填料壽命也短。解決這個問題，較好的辦法就是用旅轉(zhuǎn)閥閥桿，即角行程類的調(diào)節(jié)閥，它的閥桿比直行程閥桿粗2～3倍，且選用壽命長的石墨填料，閥桿剛度好，填料壽命長，其摩擦力矩反而小、回差小。使用刀閘閥閥門能提高輸送管路系統(tǒng)的關(guān)閉密封性能。</p><div
