style="text-indent:25px">船用閥門?相關(guān)知識：截止閥是指關(guān)閉件（閥瓣）沿閥座中心線移動的閥門。根據(jù)閥瓣的這種移動形式，閥座通口的變化是與閥瓣行程成正比例關(guān)系。由于該類閥門的閥桿開啟或關(guān)閉行程相對較短，而且具有非?？煽康那袛喙δ?，又由于閥座通口的變化與閥瓣的行程成正比例關(guān)系，非常適合于對流量的調(diào)節(jié)。因此，這種類型的閥門非常適合作為切斷或調(diào)節(jié)以及節(jié)流使用。其選用原則是： 1、高溫、高壓介質(zhì)的管路或裝置上宜選用截止閥。如火電廠、核電站，石油化工系統(tǒng)的高溫、高壓管路上，上海閥門控制系統(tǒng)廠家。 2，上海閥門控制系統(tǒng)廠家，上海閥門控制系統(tǒng)廠家、管路上對流阻要求不嚴(yán)的管路上。即對壓力損失考慮不大的地方。執(zhí)行單元包括液壓驅(qū)動器和閥門。上海閥門控制系統(tǒng)廠家</p><div

style="text-indent:25px">船用閥門常見問題該如何處理：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。上海閥門控制系統(tǒng)廠家電-液式閥門遙控系統(tǒng)和液動式閥門遙控系統(tǒng)相比較，有所不同。</p><div
