角式氨用截止閥產品簡介： ?????氨用截止閥的密封面采用巴氏合金、四氟、尼龍等。使用壽命長。是安裝在制冷系統的設備或管路上，用以接通和切斷制冷工質流動的通道，在使用過程中遇到溫差幅度變動環境下能自然達到化學處理性能。適于溫度-40~ 150攝氏度的氨、氨液介質的管路及液化氣管路上作啟閉作用。主要適用于冷凍、制冷、化工、石油、食品、冶煉、液化氣等單位使用。 角式氨用截止閥工作原理： ???? J44B角式氨用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)，也有升降旋轉桿式(手輪與閥桿一起旋轉升降，螺母設在閥體上)。截止閥只適用于全開和全關，不允許作調節和節流。 角式氨用截止閥產品特點： 1、中通法蘭為方形結構，閥桿采用間桿連接。 2、閥體密封面部位采用球凸狀，與閥腳以線吻合密封。 3、密封面采用巴氏合金，密封性能好，使用壽命長。 角式氨用截止閥產品零部件： ? tttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt
