style="text-indent:25px">船用閥門?相關(guān)知識(shí)：截止閥是指關(guān)閉件（閥瓣）沿閥座中心線移動(dòng)的閥門。根據(jù)閥瓣的這種移動(dòng)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(duì)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(duì)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。 2、管路上對(duì)流阻要求不嚴(yán)的管路上。即對(duì)壓力損失考慮不大的地方。常州氣動(dòng)閥門控制系統(tǒng)報(bào)價(jià)控制單元包括遠(yuǎn)程控制板和現(xiàn)場(chǎng)控制板。</p><div
