Lub welded flange yog ib tug detachable kev twb kev txuas qauv uas ua tiav sealing los ntawm compressing gaskets los ntawm bolt preload. Nws lub hauv paus ntsiab lus tseem ceeb suav nrog kev siv gasket deformation ntawm flange sealing nto los sau qhov khoob thiab tiv thaiv qhov nruab nrab to. cov
Txoj kev sib txuas
Ob lub flange discs tau ruaj ntseg ua ke nrog bolts, sandwiching lub gasket (xws li, graphite, hlau-mob gasket, thiab lwm yam) ntawm lawv. Lub preload compresses lub gasket, sau microscopic irregularities ntawm lub flange sealing nto los tsim ib lub foob. cov
Sealing tej yam kev mob
Preload Theem: Bolt preload yuav tsum ua tiav lub gasket preload siab Ntau dua los yog sib npaug rau preload sealing siab.
Kev khiav hauj lwm theem: Nyob rau hauv xov xwm siab, lub residual siab yuav tsum siab tshaj los yog sib npaug rau kev khiav hauj lwm sealing siab. cov
Welded Flange Hom
Butt-Weld Flange: Corner weld kev sib txuas, qauv yooj yim, haum rau nruab nrab - tsis tshua muaj siab (0.6-4.0MPa). cov
Qhov (socket) Weld Flange: Butt weld txuas, haum rau kev kub siab (1-25MPa) thiab cov ntawv thov tseem ceeb. cov
Daim ntawv thov
Siv dav hauv tshuaj, tshuaj, thiab lwm yam lag luam rau kev sib txuas cov kav dej thiab cov khoom siv, muab ob qho tib si txhim khu kev qha sealing thiab disassembly muaj peev xwm.
