低溫法蘭截止閥
英文名稱:Low flange valve
低溫截止閥型號:DJ41F-16P
低溫截止閥說明:
低溫截止閥的啟閉件也是塞形的閥瓣,密封上面呈平面或海錐面,閥瓣沿閥座的中心線作直線運動。低溫截止閥,閥門經(jīng)過低溫處理,閥門可以耐低溫,在低溫的條件下使用也沒有問題。
低溫截止閥的選用:
1、低溫截止閥在管路上對流阻要求不嚴的管路上,閥門也可以暢通無阻。
2、低溫截止閥可以有流量調(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。
低溫截止閥工作原理原理:
低溫截止閥的閥桿軸線與閥座密封面垂直。低溫截止閥閥桿開啟或關閉行程相對較短,并具有非??煽康那袛鄤幼?,使得這種閥門非常適合作為介質(zhì)的切斷或調(diào)節(jié)及節(jié)流使用。
