Yiziphi izinhlobo ezijwayelekile zokuvala ama-flange?

1. Ubuso obugcwele (FF):
I-flange inobuso obushelelezi, isakhiwo esilula, nokucubungula okulula.Ingasetshenziswa ezimweni lapho ingcindezi ingekho phezulu noma izinga lokushisa lingekho phezulu.Kodwa-ke, indawo yokuxhumana phakathi kwendawo yokuvala kanye ne-gasket inkulu, idinga amandla amakhulu okucindezela.Ngesikhathi sokufakwa, i-gasket akufanele ibekwe, futhi ngemva kokuqinisa ngaphambili, i-gasket kulula ukunweba noma ukuhambisa ezinhlangothini zombili.Uma usebenzisa ama-flange anemigqa noma ama-non-metallic flange, i-FF surface flange iqinisekisa ukuthi indawo yokubeka uphawu ayinqamuki ngesikhathi sokuqinisa, ikakhulukazi i-FF surface.

2 Ubuso Obuphakanyisiwe (RF):
Inesakhiwo esilula nokucutshungulwa okulula, futhi ingasetshenziswa ezimweni lapho ingcindezi ingekho phezulu kakhulu noma izinga lokushisa lingekho phezulu kakhulu.Kodwa-ke, abanye abantu bakholelwa ukuthi ukusebenzisa ama-gaskets ngaphansi kwengcindezi ephezulu kungenzeka.
Ngenxa yokufakwa kwayo kalula, le flange iyifomu elisetshenziswa kabanzi lokuvala elingaphansi kwe-PN 150.

3. Ubuso Bowesilisa Nowesifazane (MFM):
Ihlanganisa indawo eqondile kanye ne-convex, i-gasket ibekwe endaweni eyi-concave.Uma kuqhathaniswa nama-flange ayisicaba, ama-concave convex flange gasket awathambekele kangako ekucindezelweni, kulula ukuhlangana, futhi anobubanzi bengcindezi yokusebenza enkulu kuneama-flanges aphansi, okubenza bafanelekele izidingo eziqinile zokubeka uphawu.Kodwa-ke, ngemishini enamazinga okushisa aphezulu okusebenza kanye nama-diameter amakhulu okuvala, abanye abantu bakholelwa ukuthi i-gasket isengakhanywa uma usebenzisa le ndawo yokuvala.

4. Ulimi lobuso be-flange (TG)
Indlela ye-mortise groove flange iqukethe i-groove surface kanye ne-groove surface, futhi i-gasket ifakwe emgodini.Njengama-concave nama-convex flanges, i-tenon ne-groove flanges ayicindezeli emiseleni, ngakho-ke indawo yabo yokucindezela incane futhi i-gasket igcizelelwe ngokulinganayo.Ngenxa yokuthi akukho ukuthintana okuqondile phakathi kwe-gasket ne-medium, okuphakathi kunomthelela omncane ekugqwaleni nasekucindezelweni kwendawo yokuvala i-flange.Ngakho-ke, ivame ukusetshenziswa ezikhathini ezinezidingo eziqinile zokuvala ukucindezela okuphezulu, okuvutha umlilo, ukuqhuma, imidiya enobuthi, njll. Le gasket yendawo yokuvala ilula futhi inenzuzo ngesikhathi sokufakwa, kodwa ukucubungula nokushintshwa kwayo kuzoba nzima nakakhulu.

5. Khalisa Ubuso Obuhlangene (RJ)
I-flange sealing surface gasket ibekwe emseleni we-annular.Beka i-gasket emgodini wendandatho ukuze ingacindezeli emseleni, ngendawo encane yokucindezela kanye namandla afanayo ku-gasket.Ngenxa yokuthi akukho ukuthintana okuqondile phakathi kwe-gasket ne-medium, okuphakathi kunomthelela omncane ekugqwaleni nasekucindezelweni kwendawo yokuvala i-flange.Ngakho-ke, ivame ukusetshenziswa ezikhathini ezinezidingo eziqinile zokuvalwa kokucindezela okuphezulu, okuvutha umlilo, ukuqhuma, imidiya enobuthi, njll.
Ngamafuphi, amafomu angaphezulu okuvala ama-flange ahlukile, futhi izici zawo kanye nobubanzi bokusebenza nakho kuhlukile.Ngakho-ke, lapho sikhetha i-flange, kufanele sinake ukusetshenziswa kwayo kanye nezidingo zokusebenza.Isibonelo, uma umsebenzi ungenalo ukhahlo, khetha iI-RF seal surface, futhi lapho izimo zokusebenza zinzima, khetha indawo yokuvalwa kwe-RJ ehlangabezana ngokugcwele nezimfuneko zokuvala;Kungcono ukusebenzisa indawo ye-FF kumaphayiphi angewona awensimbi noma ane-lined flange anengcindezi ephansi.Isimo esiqondile sincike ezidingweni zangempela.
