詳細介紹

J41W-600Lb 美標截止閥

產品引用標準：

　　設計與制造：ANSI B16.34
　　結構長度：ANSI B16.10
　　壓力溫度等級：ANSI B16.34
　　連接法蘭：ANSI B16.5
　　試驗與檢驗：API598

產品用途：

　　法蘭連接的鑄銅截止閥適用于ANSI Class 150～2500Lb，工作溫度≤600℃的石油、化工、火力電站等各種工況的管路上，切斷或接通介質。適用介質為：水、油品、蒸汽等。操作方式有：手動、齒輪傳動、電動、氣動等。

產品結構特點：

1.采用中法蘭螺紋連接，支管兩端為法蘭連接結構，可與進口設備配套使用。
2.閥瓣、閥座的密封面采用司太立（slite）鈷基硬質合金堆焊而成，耐磨。
3.閥桿經調質和表面氮化處理，有良好的搞腐蝕性和抗擦傷性。
4.法蘭密封采用金屬環墊，強度高、密封可靠，耐用性好。
5.1500LB ∽2500LB中腔采用壓力自緊式密封結構。密封性能隨內壓升高而升高，可靠性高。
6.倒密封采用不銹鋼螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，密封可靠，填料更換可在不停機情況下進行，方便快捷不影響系統運行。
