J541H-100C傘齒輪截止閥J541H-100C
【簡單介紹】
【詳細說明】
截止閥概述:截止閥(stop valve/globe valve)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(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。
?。?)、截止閥具有以下優(yōu)點:
1、結(jié)構(gòu)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。
?。?)、截止閥的安裝與維護應(yīng)注意以下事項:
1、手輪、手柄操作的截止閥可安裝在管道的任何位置上。
2、手輪、手柄及傳動機構(gòu),不允許作起吊用。
3、介質(zhì)的流向應(yīng)與閥體所示箭頭方向*。
