截止閥標(biāo)準(zhǔn)大全|截止閥的作用
一、編輯整理截止閥標(biāo)準(zhǔn)意義何在？
信茂截止閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運動。閥桿的運動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉(zhuǎn)桿式（手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上）。截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。
由于截止閥種類繁多，同一個截止閥可以做成不同的標(biāo)準(zhǔn)，不同的標(biāo)準(zhǔn)在管道連接，試驗壓力以及管道使用都有差別，為了您在使用的時候，能將截止閥對號入座，信茂技術(shù)部特編輯整體出截止閥的標(biāo)準(zhǔn)大全，供您參考！落實到工況比較特殊的場合，建議您聯(lián)系我們技術(shù)部，為您做選型把關(guān)，避免不必要的損失。

三、信茂截止閥的作用：
截止閥在管道起著舉足輕重的作用，大家在選用截止閥的時候，一定要配合截止閥的優(yōu)缺點，截止閥的工作原理，截止閥的適用范圍，然后結(jié)合截止閥的型號編制和截止閥的分類，對截止閥進(jìn)行精確的選擇，以最大限度的發(fā)揮出截止閥的作用。下面是截止閥落實到具體工況的作用。
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、管路上對流阻要求不嚴(yán)的管路上。即對壓力損失考慮不大的地方，可以選用截止閥。
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(diào)節(jié)或壓力調(diào)節(jié)，但對調(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(jié)焦的管路上，易選用閥體分開式、閥座可去處的、硬質(zhì)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(shè)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。 最明顯的優(yōu)點是： 在開啟和關(guān)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。 開啟高度一般僅為閥座通道直徑的1/4，因此比閘閥小的多。 通常在閥體和閥瓣上只有一個密封面，因而制造工藝性比較好，便于維修。
