Z61Y-鍛鋼閘閥
鍛鋼閘閥有三種閥蓋設計，第一種是(shì)螺栓型閥蓋，通(tōng)過凹凸面連(lián)接，采用不鏽鋼帶與柔性石墨纏繞墊(niàn)片，按需求(qiú)也可采用環連接，第二種是焊接型閥蓋，通過螺紋密封後焊(hàn)接，按(àn)需求也可(kě)直接采用剛性焊接，第三(sān)種是(shì)自密(mì)封閥(fá)蓋，通(tōng)過螺紋(wén)與自密封閥蓋連接。
鍛鋼閘閥的結構(gòu)設計與規範：
鍛鋼閘閥制造按API 602,BS5352,ANSI B16.34.
試驗與驗收按API 598,标識(shí)按照MSS SP-25.
結構型式如下：
1.全通徑或縮徑；
2.明杆帶支架；
3.兩端自動調心的填料壓套；
4.用纏繞式墊片的螺栓型閥蓋、螺紋密封焊接型閥蓋，或自密封閥蓋
5.本(běn)體倒密封；
6.承插焊接(jiē)ANSI/ASME B16.11;
7.螺紋端(NPT端(duān))按ANSI/ASME B1.20.1。
