由于該類閥門的閥桿開啟或關閉行程相對較短，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系，非常適合于對流量的調節(jié)。因此，這種類型的閥門非常適合作為切斷或調節(jié)以及節(jié)流使用。截止閥的選用原則是：1、高溫、高壓介質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、管路上對流阻要求不嚴的管路上。即對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、壓力計閥等。4、有流量調節(jié)或壓力調節(jié)，但對調節(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。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的高壓角式截止閥或高壓角式節(jié)流閥。6、氧化鋁拜耳法生產(chǎn)中的脫硅車間、易結焦的管路上，易選用閥體分開式、閥座可去處的、硬質合金密封副的直流式截止閥或直流式節(jié)流閥。7、城市建設中的供水、供熱工程上，公稱通經(jīng)較小的管路，可選用截止、平衡閥或柱塞閥，如公稱通經(jīng)小于150mm的管路上。優(yōu)明顯的優(yōu)點是：在開啟和關閉過程中，由于閥瓣于閥體密封面間的摩擦力比閘閥小，因而耐磨。鎮(zhèn)江H47H碟式緩沖止回閥</p><p
