一、J47H高壓角式截止閥概述：
J47H高壓角式截止閥、節流閥，J47H高壓平衡角式截止、節流閥原理，J47H高壓平衡角式截止、節流閥規格，J47H高壓平衡角式截止、節流閥廠家，J47H高壓平衡角式截止、節流閥報價
J44H角式截止閥，J44H角式截止閥原理，J44H角式截止閥規格，J44H角式截止閥廠家，J44H角式截止閥報價
截止閥是指關閉件(閥瓣)沿閥座中心線移動的閥門。根據閥瓣的這種移動形式，閥座通口的變化是與閥瓣行程成正比例關系。由于該類閥門的閥桿開啟或關閉行程相對較短，而且具有非常可靠的切斷功能，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。因此，這種類型的閥門非常適合作為切斷或調節以及節流使用。

J47H高壓���式截止閥選用原則是：
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、有流量調節或壓力調節，但對調節精度要求不高，而且管路直徑又比較小，如公稱通經≤50mm 的管路上，宜選用。
5、合成工業生產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流閥。
6、氧化鋁拜耳法生產中的脫硅車間、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流閥。
7、城市建設中的供水、供熱工程上，公稱通經較小的管路，可選用截止、平衡閥或柱塞閥，如公稱通經小于150mm的管路上。 *明顯的優點是：
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。 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。
截止閥優點
1、結構簡單，制造和維修比較方便。
2、工作行程小，啟閉時間短。
3、密封性好，密封面間磨擦力小，壽命較長。
