Umahluko phakathi kweFF Flange kunye neRF Flange yokutywina uMphezulu

Kukho iindidi ezisixhenxe zomphezulu wokutywina we-flange: ubuso obugcweleyo FF, ubuso obuphakanyisiweyo be-RF, ubuso obuphakanyisiweyo M, ubuso be-concave FM, ubuso be-tenon T, ubuso be-groove G, kunye ne-ring joint face RJ.

Phakathi kwazo, inqwelomoya epheleleyo i-FF kunye ne-convex RF zisetyenziswa ngokubanzi, ngoko ke ziyaziswa kwaye zahlulwa ngokweenkcukacha.

FF ubuso obugcweleyo

Ukuphakama komphezulu woqhagamshelwano weflange ecaba (FF) iyafana nomgca wodibaniso lwebholithi yeiflange.I-gasket yobuso obugcweleyo, ehlala ithambile, isetyenziswa phakathi kweebiniiiflange ezisicaba.

Ubuso obuthe tyaba bubuso obugcweleyo bohlobo lokutywina umphezulu buthe tyaba ngokupheleleyo, obulungele iimeko ezinoxinzelelo oluphantsi kunye ne-non-toxic medium.

I-RF iphakamise ubuso

Iiflange zobuso obuphakanyisiweyo (RF) zichongwa ngokulula ngenxa yokuba indawo yomphezulu we-gasket ingaphezulu komgca obotiweyo weflange.

Umphezulu wokutywina wobuso obunyusiweyo ngowona usetyenziswa kakhulu phakathi kweentlobo ezisixhenxe.Imigangatho yamazwe ngamazwe, iinkqubo zaseYurophu kunye nemigangatho yasekhaya yonke inobude obusisigxina.Nangona kunjalo, kwi

Iiflange eziqhelekileyo zaseMelika, kufuneka kuqatshelwe ukuba ukuphakama koxinzelelo oluphezulu kuya kwandisa ukuphakama kwendawo yokutywinwa.Kukho neentlobo ezininzi zeegaskets.

Iigaskets ze-RF zokutywinwa kobuso obuphakanyisiweyo bubandakanya iigaskets ezahlukeneyo ezingeyontsimbi kunye neegasket ezisongelweyo;I-gasket esongiweyo yesinyithi, i-spiral inxeba gasket (kubandakanya iringi yangaphandle okanye yangaphakathi

umsesane), njl.

Umahluko

Uxinzelelo lweFF ubuso obugcweleyoincinci ngokubanzi, ayidluli kwi-PN1.6MPa.Indawo yoqhagamshelwano yokutywina ye-FF egcwele ubuso beflange inkulu kakhulu, kwaye kukho iindawo ezininzi ngaphaya koluhlu

umphezulu wokutywina osebenzayo.Akunakuphepheka ukuba indawo yokutywina ayiyi kuqhagamshelana kakuhle, ngoko umphumo wokutywina awulungile.Indawo yokunxibelelana yobuso obunyusiweyo beflange yokutywina incinci, kodwa yona

isebenza kuphela kuluhlu lwendawo yokutywina esebenzayo, kuba isiphumo sokutywina singcono kunobuso obugcweleyo beflange.
