聯(lián)系我時,請告知來自 制藥網(wǎng)楔式閘閥產(chǎn)品概述:
閘閥是作為截斷和接通流體使用,在全開時整個流通直通,此時介質(zhì)運行的壓力損失小。閘閥通常適用于不需要經(jīng)常啟閉,而且保持閘板全開或全閉的工況。不適用于作為調(diào)節(jié)或節(jié)流使用。閘閥廣泛適用于石油化工,火力發(fā)電廠等油品、水蒸氣管路上作接通或截斷管路中介質(zhì)的啟閉裝置。
產(chǎn)品特點:
1、結(jié)構(gòu)緊湊、設(shè)計合理、閥門剛性好、通道流暢,流量系數(shù)小
2、密封面采用不銹鋼和硬質(zhì)合金,使用壽命長
3、采用柔性石墨填料、密封可靠,操作輕便靈活
4、驅(qū)動方式為手動、氣動、電動、齒輪傳動
5、結(jié)構(gòu)形式為彈性楔式單閘板、剛性楔式單閘板雙閘板型式
閘閥執(zhí)行標準:
設(shè)計規(guī)范:GB/T 12234-2007
結(jié)構(gòu)長度:GB/T 12221-2005
連接法蘭:HG/T20592-2009
