1. Ubuso Obuphakanyisiwe (RF):
Indawo engaphezulu iyindiza ebushelelezi futhi ingaba nemisele emise okwemisele. Indawo yokubeka uphawu inesakhiwo esilula, kulula ukuyikhiqiza, futhi ifanele ulwelwesi olulwa nokugqwala. Kodwa-ke, lolu hlobo lokuvala uphawu lunendawo enkulu yokuxhumana ye-gasket, okwenza kube lula ukukhishwa kwe-gasket ngesikhathi sokuqina kwangaphambili, okwenza kube nzima ukufeza ukucindezela okufanele.
2. Owesilisa-Owesifazane (MFM):
Indawo evalayo iqukethe i-convex ne-concave surface elingana ndawonye. I-gasket ibekwe endaweni eyi-concave, evimbela i-gasket ukuthi ingakhishwa. Ngakho-ke, ilungele izinhlelo zokusebenza ezinomfutho ophezulu.
3. Ulimi neGroove (TG):
Indawo yokuvala yakhiwe ngezilimi nemigodi, ne-gasket ebekwe emseleni. Ivimbela i-gasket ukuthi ingasuswa. Ama-gaskets amancane angasetshenziswa, okuholela ekutheni kube namandla aphansi webhawodi adingekayo ukuze kucindezelwe. Lo mklamo uphumelela ekufinyeleleni uphawu oluhle, ngisho nasezimweni zokucindezela okukhulu. Kodwa-ke, i-drawback ukuthi ukwakheka kanye nenqubo yokukhiqiza kuyinkimbinkimbi, futhi ukufaka esikhundleni se-gasket emseleni kungaba inselele. Ukwengeza, ingxenye yolimi isengozini yokulimala, ngakho-ke kufanele kuqashelwe ngesikhathi sokuhlanganisa, ukuqaqa, noma ukuthuthwa. Izindawo zokuvala ulimi nemigodi zifanele izinto ezivuthayo, eziqhumayo, ezinobuthi, kanye nezinhlelo zokusebenza ezinomfutho ophezulu. Ngisho nobubanzi obukhulu, basengakwazi ukunikeza uphawu oluphumelelayo lapho ukucindezela kungaphakeme kakhulu.
4. I-Saky Steel Full Face (FF) kanyeI-Ring Joint (RJ):
Ukuvala ubuso obugcwele kulungele izinhlelo zokusebenza ezinengcindezi ephansi (PN ≤ 1.6MPa).
Indawo ehlangene yendandatho isetshenziselwa ikakhulukazi ama-flange ashiselwe entanyeni kanye nama-flange abalulekile, afanele ububanzi bengcindezi (6.3MPa ≤ PN ≤ 25.0MPa).
Ezinye Izinhlobo Zezindawo Zokuvala:
Ngemikhumbi enengcindezi ephezulu kanye namapayipi okucindezela okuphezulu, izindawo zokuvala uphawu ze-conical noma izindawo zokuvala i-trapezoidal groove zingasetshenziswa. Abhangqwe nama-gaskets ensimbi ayindilinga (ama-lens gaskets) kanye nama-gaskets ensimbi anezigaba ezinqamulayo eziyi-elliptical noma ezine-octagonal, ngokulandelana. Lezi zindawo zokuvala zilungele izinhlelo zokusebenza ezinengcindezi ephezulu kodwa zidinga ukunemba kobukhulu obuphezulu kanye nokuqedwa kwangaphezulu, okwenza kube inselele emshinini.
