Umehluko Phakathi kwe-FF Flange kanye ne-RF Flange Yokuvala Indawo

Kunezinhlobo eziyisikhombisa zezindawo zokuvalwa kwe-flange: ubuso obugcwele u-FF, ubuso obuphakanyisiwe be-RF, ubuso obuphakanyisiwe M, ubuso be-concave FM, ubuso be-tenon T, ubuso be-groove G, nobuso obuhlangene beringi u-RJ.

Phakathi kwazo, indiza egcwele i-FF ne-convex RF isetshenziswa kabanzi, ngakho-ke yethulwa futhi ihlukaniswa ngokuningiliziwe.

FF ubuso obugcwele

Ukuphakama kwendawo yokuxhumana ye-flange eyisicaba (FF) kuyafana nolayini wokuxhuma webhawodi wei-flange. I-gasket yobuso obugcwele, ngokuvamile ethambile, isetshenziswa phakathi kokubiliama-flanges aphansi.

Ubuso obuyisicaba obugcwele uhlobo lokuvala ubuso buyisicaba ngokuphelele, obufanele izikhathi ezinomfutho ophansi kanye nendawo engenabuthi.

RF ubuso obuphakanyisiwe

Ama-flange obuso aphakanyisiwe (RF) abonakala kalula ngoba indawo ye-gasket ingaphezu komugqa oboshiwe we-flange.

Indawo yokubekwa uphawu yobuso obuphakanyisiwe iyona esetshenziswa kakhulu phakathi kwezinhlobo eziyisikhombisa. Izindinganiso zamazwe ngamazwe, izinhlelo zaseYurophu kanye nezindinganiso zasekhaya zonke zinokuphakama okungashintshi. Nokho, ku

Ama-flange ajwayelekile aseMelika, kufanele kuqashelwe ukuthi ukuphakama kokucindezela okuphezulu kuzokwandisa ukuphakama kwendawo yokubeka uphawu. Kukhona nezinhlobo eziningi zama-gaskets.

Ama-gasket e-RF ama-flange obuso obuvaliwe obuso obuphakanyisiwe afaka ama-gaskets ayisicaba angewona awensimbi kanye nama-gaskets asongwe; I-gasket egoqwe ngensimbi, i-spiral wound gasket (kufaka phakathi iringi yangaphandle noma yangaphakathi

indandatho), njll.

Umehluko

Ingcindezi yeI-FF igcwele ubuso obugcwelengokuvamile incane, ayidluli ku-PN1.6MPa. Indawo yokuxhumana yokuvala ye-FF egcwele ubuso obugcwele inkulu kakhulu, futhi kunezingxenye eziningi kakhulu ngale kobubanzi

indawo yokubeka uphawu ephumelelayo. Akunakugwema ukuthi indawo yokuvala ngeke ithinte kahle, ngakho-ke umphumela wokuvala awumuhle. Indawo yokuxhumana ye-face flange sealing surface incane, kodwa yona

isebenza kuphela ngaphakathi kwebanga lendawo yokuvala ephumelelayo, ngoba umphumela wokuvala ungcono kunowobuso obugcwele be-flange.
