Z61Y-鍛鋼閘閥
鍛鋼(gāng)閘閥有三種(zhǒng)閥蓋設計，第(dì)一種是螺栓(shuān)型閥蓋，通過(guò)凹凸面連接(jiē)，采用⛹🏻♀️不鏽鋼(gāng)帶與柔性石(shi)墨纏繞墊片(pian)，按需求也🐆可(ke)采用環連接(jiē)，第二種是焊(han)接型閥蓋，通(tōng)過螺紋密封(fēng)🎯後焊接，按需(xū)求⛷️也可直接(jiē)采用剛性焊(hàn)接，第三種是(shi)自密封閥蓋(gai)，通過螺紋與(yǔ)自密封閥蓋(gài)連接。
鍛鋼閘(zhá)閥的結構設(shè)計與規範：
鍛(duàn)鋼閘閥制造(zào)按API 602,BS5352,ANSI B16.34.
試驗與驗(yan)收按API 598,标識按(an)照MSS SP-25.
結構型式(shi)如下：
1.全通徑(jing)或縮徑；
2.明杆(gǎn)帶支架；
3.兩端(duān)自動調心的(de)填料壓套；
4.用(yòng)纏繞式墊片(pian)的螺栓型閥(fá)蓋、螺紋密封(feng)焊接型閥蓋(gài)，或自密封閥(fá)蓋
5.本體倒密(mi)封；
6.承插焊接(jiē)ANSI/ASME B16.11;
7.螺紋端(NPT端)按(àn)ANSI/ASME B1.20.1。
