水封截止閥適用于公稱壓力PN2.5～6.4MPa,工作溫度0～450℃的火力電站回水冷凝系統(tǒng)及石油、化工要求與大氣隔離的系統(tǒng)管道上，切斷或接通管路中的介質(zhì).
◆執(zhí)行標(biāo)準(zhǔn)
設(shè)計(jì)與制造：JB/T3595
結(jié)構(gòu)長(zhǎng)度：GB/T15188.1
壓力溫度等級(jí)：GB/T3595
試驗(yàn)與檢驗(yàn)：GB13927 JB/T9092
◆產(chǎn)品特點(diǎn)
1、產(chǎn)品按國(guó)家標(biāo)準(zhǔn)GB12235設(shè)計(jì)制造，結(jié)構(gòu)新穎，選材合理,造形美觀。連接端有法蘭和焊接，可根據(jù)用戶不同要求配接
2、填料函設(shè)計(jì)成水密封結(jié)構(gòu)，接入0.6~1.6Mpa的水填料，摩擦力小，密封好，能全系統(tǒng)與大氣隔離，保證良好的氣密性
3、閥桿經(jīng)調(diào)質(zhì)和表面氮化處理，有良好的搞腐蝕性和抗擦傷性
4、結(jié)構(gòu)緊湊，操作靈活，檢修方便，使用壽命長(zhǎng)
5、倒密封采用不銹鋼螺紋連接密封座或本體堆焊奧氏體不銹鋼而成，倒密封可靠。填料更換和維修可在不停機(jī)情況下進(jìn)行，方便快捷不影響系統(tǒng)運(yùn)行
