一、J47H高壓角式截止閥概述：

    J47H高壓角式截止閥、節(jié)流閥，J47H高壓平衡角式截止、節(jié)流閥原理，J47H高壓平衡角式截止、節(jié)流閥規(guī)格，J47H高壓平衡角式截止、節(jié)流閥廠家，J47H高壓平衡角式截止、節(jié)流閥報(bào)價(jià) J44H角式截止閥，J44H角式截止閥原理，J44H角式截止閥規(guī)格，J44H角式截止閥廠家，J44H角式截止閥報(bào)價(jià) 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。

J47H高壓角式截止閥選用原則是：

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。

3、小型閥門可選用針閥、儀表閥、取樣閥、壓力計(jì)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。

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(diǎn)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(gè)密封面，因而制造工藝性比較好，便于維修。
截止閥優(yōu)點(diǎn)
1、結(jié)構(gòu)簡(jiǎn)單，制造和維修比較方便。 
2、工作行程小，啟閉時(shí)間短。 
3、密封性好，密封面間磨擦力小，壽命較長。
