角式氨用截止閥產(chǎn)品簡(jiǎn)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(zhǎng)。是安裝在制冷系統(tǒng)的設(shè)備或管路上，用以接通和切斷制冷工質(zhì)流動(dòng)的通道，在使用過程中遇到溫差幅度變動(dòng)環(huán)境下能自然達(dá)到化學(xué)處理性能。適于溫度-40~ 150攝氏度的氨、氨液介質(zhì)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(yùn)動(dòng)。閥桿的運(yùn)動(dòng)形式，有升降桿式(閥桿升降，手輪不升降)，也有升降旋轉(zhuǎn)桿式(手輪與閥桿一起旋轉(zhuǎn)升降，螺母設(shè)在閥體上)。截止閥只適用于全開和全關(guān)，不允許作調(diào)節(jié)和節(jié)流。 角式氨用截止閥產(chǎn)品特點(diǎn)： 1、中通法蘭為方形結(jié)構(gòu)，閥桿采用間桿連接。 2、閥體密封面部位采用球凸?fàn)，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(zhǎng)。 角式氨用截止閥產(chǎn)品零部件： ? tttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt
