style="text-indent:25px">電站焊接截止閥較明顯的優(yōu)點(diǎn)是：在開啟和關(guān)閉過(guò)程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。焊接截止閥開啟高度一般*為閥座通道直徑的1/4，因此比閘閥小的多。通常在閥體和閥瓣上只有一個(gè)密封面，因而制造工藝性比較好，便于維修。焊接截止閥的選用原則是： 1、高溫、高壓介質(zhì)的管路或裝置上宜選用焊接截止閥。如火電廠、核電站，石油化工系統(tǒng)的高溫、高壓管路上。 2、焊接截止閥用在管路上對(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。 3、小型閥門可選用針閥、儀表閥、取樣閥、壓力針閥等。 4、有流量調(diào)節(jié)或壓力調(diào)節(jié)，但對(duì)調(diào)節(jié)精度要求不高，而且管路直徑又比較小，如公稱通經(jīng)≤50mm 的管路上，宜選用焊接截止閥。 5、合成工業(yè)生產(chǎn)中的小化肥和大化肥宜選用公稱壓力PN160 公稱壓力16MPa 或PN320 公稱壓力32MPa 的高壓角式焊接截止閥或高壓角式節(jié)流閥。</p><p
