產(chǎn)品說(shuō)明:
J941Y型電動(dòng)法蘭截止閥PN16~PN160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(kāi)和全關(guān),不允許作調(diào)節(jié)和節(jié)流。
產(chǎn)品特點(diǎn)及用途:
1、結(jié)構(gòu)緊湊、設(shè)計(jì)合理,閥門剛性好,通道流暢,流阻系數(shù)小。
2、密封面采用不銹鋼和硬質(zhì)合金,使用壽命長(zhǎng)
3、采用柔性石墨填料、密封可靠、操作輕便靈活
4、驅(qū)動(dòng)方式分手動(dòng)、電動(dòng)、氣動(dòng)、齒輪傳功,結(jié)構(gòu)型式:彈性楔式單閘板、剛性楔式單閘板和雙閘板型式.
5、廣泛適用于石油化工,火力發(fā)電廠等油品、水蒸汽管路上作接通或截?cái)喙苈分薪橘|(zhì)的啟閉裝置。

截止閥的結(jié)構(gòu)形式:
截止閥閥體的結(jié)構(gòu)形式有直通式、直流式和直角式。直通式是zui常見(jiàn)的結(jié)構(gòu),但其流體的阻力zui大。直流式流體阻力較小,多用于含固體顆?;蛘扯却蟮牧黧w。直角式閥體多采用鍛造,適用于較小通經(jīng)、較高壓力的的截止閥。
截止閥的安裝與維護(hù)注意事項(xiàng):
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(dòng)機(jī)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*;
