style="text-indent:25px">什么是鍛鋼波紋管截止閥？上海卓帕真空技術(shù)有限公司**介紹，鍛鋼波紋管截止閥主要適用于火力電站各種系統(tǒng)的管路上，切斷或接通管路介質(zhì)。適用介質(zhì)：水、蒸氣等非腐蝕性介質(zhì)。鍛鋼波紋管截止閥與其他閥門產(chǎn)品相比的特點(diǎn)是高溫高壓，獨(dú)特的自密封設(shè)，壓力越高，密封越可靠。由于性能技術(shù)特性、工況的特殊使產(chǎn)品也形成了其他產(chǎn)品所替代不了的特點(diǎn)。鍛鋼波紋管截止閥有二種閥蓋設(shè)計(jì)形式。一種是螺栓式閥蓋，按這種形式設(shè)計(jì)的閥門，其閥體與閥蓋用螺栓螺母連接，纏繞式墊片（316夾柔性石墨制造）密封?？蛻粲刑厥庖髸r(shí)也可采用金屬環(huán)連接。第二種設(shè)計(jì)形式是焊接式閥蓋，按這種形式設(shè)計(jì)的閥門，其閥體與閥蓋用螺紋連接，全焊密封?？蛻粲刑厥庖髸r(shí)也可采用全焊透連接。吉林單壁波紋管設(shè)備波紋管閘閥的種類按閥桿螺紋的位置分有外螺紋式、內(nèi)螺紋式。</p><div
