Z61Y-鍛鋼閘閥(fá)
鍛鋼(gāng)閘閥有三種閥(fa)蓋設計，跳🔞蛋露出🚩第一種(zhong)是螺栓型閥蓋(gài)，通過凹凸面連(lian)接，采㊙️用不鏽鋼(gāng)帶與柔性石墨(mò)纏繞墊片，按需(xu)求也🍉可采用環(huan)🧡連接🏃，第二種是(shì)焊接型閥蓋，通(tōng)過螺紋密封後(hòu)焊接，按需求也(ye)可直接采用剛(gāng)性焊接，第三種(zhong)是自🐪密封閥蓋(gai)，通過螺紋💋與自(zi)密封閥蓋連接(jiē)。
鍛鋼閘閥的結(jie)構設計與規範(fan)：
鍛鋼閘閥制造(zao)按API 602,BS5352,ANSI B16.34.
試驗與驗收(shou)按API 598,标識按照MSS SP-25.
結(jie)構型式如下：
1.全(quán)通徑或縮徑；
2.明(ming)杆帶支架；
3.兩端(duān)自動調心的填(tian)料壓套；
4.用纏繞(rao)式墊片的螺栓(shuan)型閥蓋、螺紋密(mì)封焊接型閥蓋(gài)，或自密封閥蓋(gài)
5.本體倒密封；
6.承(chéng)插焊接ANSI/ASME B16.11;
7.螺紋端(duān)(NPT端)按ANSI/ASME B1.20.1。
