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, 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 anengcindezi ephezulu, 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.
