Z61Y-鍛鋼(gāng)閘閥
鍛鋼(gang)閘閥有三(san)種閥蓋設(she)計，第一種(zhong)是螺栓型(xíng)閥蓋，通過(guo)凹凸面連(lian)接，采用不(bú)鏽鋼帶與(yu)柔性石墨(mò)纏繞墊片(pian)，按需求也(ye)🔴可采用環(huán)連接，第二(èr)種是焊接(jie)型閥蓋，通(tōng)過螺紋密(mi)封後焊接(jiē)，按需求也(ye)可直接采(cǎi)用剛性焊(hàn)接，第三種(zhǒng)是自密封(fēng)閥蓋，通過(guo)螺紋與自(zì)密封閥蓋(gài)連接。
鍛鋼(gang)閘閥的結(jié)構設計與(yǔ)規範：
鍛鋼(gāng)閘閥制造(zào)按API 602,BS5352,ANSI B16.34.
試驗與(yu)驗收按API 598,标(biāo)識按照MSS SP-25.
