316不銹鋼閘閥詳細(xì)概述:
316不銹鋼閘閥為不銹鋼材質(zhì),連接方式為內(nèi)螺紋與承插焊。它有三種閥蓋設(shè)計,*種是螺栓型閥蓋,通過凹凸面連接,采用不銹鋼帶與柔性石墨纏繞墊片,按需求也可采用環(huán)連接,第二種是焊接型閥蓋,通過螺紋密封后焊接,按需求也可直接采用剛性焊接,第三種是自密封閥蓋,通過螺紋與自密封閥蓋連接。
2.1W鍛鋼F304不銹鋼閘閥的結(jié)構(gòu)設(shè)計和規(guī)范:
3.紋與承插焊閘閥制造按API 602,BS5352,ANSI B16.34.
與驗收按API 598,標(biāo)識按照MSS SP-25.
F304不銹鋼結(jié)構(gòu)型式如下:
1.全通徑或縮徑;
2.明桿帶支架;
3.兩端自動調(diào)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.本體倒密封;
6.承插焊接ANSI/ASME B16.11;
7.螺紋端(NPT端)按ANSI/ASME B1.20.1。
