Izinhlobo Zezindawo Zokuvala kanye Nemisebenzi Yezindawo Zokuvala I-Flange

1. Ubuso Obuphakanyisiwe (RF):

Ubuso bubushelelezi futhi bungaba nemifantu enama-serrated. Ubuso bokuvala bunesakhiwo esilula, kulula ukubukhiqiza, futhi bufanelekela ulwelwesi olulwa nokugqwala. Kodwa-ke, lolu hlobo lobuso bokuvala lunendawo enkulu yokuxhumana ne-gasket, okwenza kube lula ukukhipha i-gasket ngesikhathi sokuqinisa, okwenza kube nzima ukufeza ukucindezelwa okufanele.

2. Owesilisa nowesifazane (MFM):

Indawo yokuvala ine-convex kanye nendawo egobile ehlangana ndawonye. I-gasket ibekwa endaweni egobile, ivimbela i-gasket ukuthi ingakhishwa. Ngakho-ke, ifanele ukusetshenziswa ngomfutho ophezulu.

3. Ulimi Nomsele (TG):

Indawo yokuvala yakhiwe ngolimi nemigoqo, lapho i-gasket ibekwe emseleni. Ivimbela i-gasket ukuthi ingasuswa. Ama-gasket amancane angasetshenziswa, okuholela emandleni aphansi ebholiti adingekayo ukuze kucindezelwe. Lo mklamo uyasebenza ekufezeni ukuvalwa okuhle, ngisho nasezimweni zokucindezela okuphezulu. Kodwa-ke, inkinga ukuthi isakhiwo kanye nenqubo yokukhiqiza kuyinkimbinkimbi kakhulu, futhi ukufaka esikhundleni i-gasket emseleni kungaba yinselele. Ngaphezu kwalokho, ingxenye yolimi isengozini yokulimala, ngakho-ke kufanele kuqashelwe ngesikhathi sokuhlanganiswa, ukuqaqwa, noma ukuthuthwa. Izindawo zokuvala ulimi nemigoqo zifanelekela ukusetshenziswa okuvuthayo, okuqhumayo, okunobuthi, kanye nokucindezela okuphezulu. Ngisho noma ububanzi obukhulu, zisenganikeza ukuvala okusebenzayo lapho ukucindezela kungaphakeme kakhulu.

4. Ubuso Obugcwele Bensimbi yeSaky Steel (FF) kanyeI-Ring Joint (RJ):

Ukuvala ubuso ngokuphelele kufanelekile ekusetshenzisweni okunomfutho ophansi (PN ≤ 1.6MPa).

Izindawo zokuhlangana kwendandatho zisetshenziswa kakhulu kuma-flange ahlanganiswe entanyeni kanye nama-flange ahlanganisiwe, afanelekela amazinga okucindezela (6.3MPa ≤ PN ≤ 25.0MPa).

Ezinye Izinhlobo Zezindawo Zokuvala:

Emikhunjini enomfutho ophezulu kanye namapayipi anomfutho ophezulu, izindawo zokuvala ezigobile noma izindawo zokuvala ezimbozwe nge-trapezoidal zingasetshenziswa. Zihambisana nama-gasket ensimbi ayindilinga (ama-gasket elensi) kanye nama-gasket ensimbi anezingxenye ezigobile noma ezilinganayo, ngokulandelana. Lezi zindawo zokuvala zifanele ukusetshenziswa komfutho ophezulu kodwa zidinga ukunemba okuphezulu kanye nokuphela kobuso, okwenza kube nzima ukuzisebenzisa ngomshini.
