鍛鋼止回閥有三種閥蓋設(shè)計(jì),*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。
止回閥還有三種不同的結(jié)構(gòu)設(shè)計(jì),分別是:立升式止回閥、球形止回閥和旋啟式止回閥。連接方式有法蘭,對(duì)焊等!
止回閥的結(jié)構(gòu)設(shè)計(jì)和規(guī)范:
止回閥制造按MSS SP-118,BS5352,ANSI/ASME B16.34,試驗(yàn)與驗(yàn)收按API 598,標(biāo)識(shí)按照MSS SP-25.
結(jié)構(gòu)型式如下:
1.全通徑或縮徑;
2.立升式止回閥
3.球形止回閥
4.旋啟式止回閥
5.可按要求采用彈簧輔助復(fù)位
6.采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
7.承插焊接ANSI/ASME B16.11
8.螺紋端(NPT端)按ANSI/ASME B1.20.1
