Z945H電動暗桿閘閥產(chǎn)品概述
Z945H-10C/Z945H-16C電動暗桿法蘭鑄鋼閘閥適用于公稱壓力PN1.6~16.0MPa,工作溫度≤-29℃~550℃的石油、化工、水力、火力電站各種系統(tǒng)的管路上,切斷或接通管路介質(zhì)。適用介質(zhì)為:水、油品、蒸氣、及酸、堿、氨、尿素、含硫天然氣等。操作方式有:手動、齒輪傳動、電動、氣動等。
Z945H電動暗桿閘閥特點及用途
1、結(jié)構(gòu)緊湊、設(shè)計合理,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
3、采用柔性石墨填料、密封可靠、操作輕便靈活
4、驅(qū)動方式分手動、電動、氣動、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斷管路中介質(zhì)的啟閉裝置。
