1. Ubuso obuphakanyisiweyo (RF):
Umphezulu uyinqwelomoya egudileyo kwaye unokuba nemijelo enqamlezileyo.Umphezulu wokutywina unesakhiwo esilula, kulula ukuwenza, kwaye ufanelekile kwi-anti-corrosion lining.Nangona kunjalo, olu hlobo lokutywinwa kwendawo lunommandla omkhulu wokudibanisa i-gasket, okwenza kube lula kwi-gasket extrusion ngexesha lokuqiniswa kwangaphambili, okwenza kube nzima ukufezekisa ukunyanzeliswa okufanelekileyo.
2. Indoda nomfazi (MFM):
Umphezulu wokutywina uquka i-convex kunye ne-concave surface edibana kunye.I-gasket ifakwe kumphezulu we-concave, ukuthintela i-gasket ukuba ikhutshwe.Ngoko ke, ifanelekile kwizicelo zoxinzelelo oluphezulu.
3. Ulwimi kunye neGroove (TG):
Umphezulu wokutywina uqulunqwe ngeelwimi kunye ne-grooves, kunye ne-gasket efakwe kwi-groove.Ikhusela i-gasket ekubeni isuswe.I-gaskets ezincinci zingasetyenziswa, okubangela ukuba kubekho amandla aphantsi e-bolt afunekayo ekucinezeleni.Olu luyilo lusebenza ngokufanelekileyo ekufezekiseni isitywina esihle, nakwiimeko zoxinzelelo oluphezulu.Nangona kunjalo, i-drawback kukuba isakhiwo kunye nenkqubo yokuvelisa inzima kakhulu, kwaye ukubuyisela i-gasket kwi-groove kunokuba ngumngeni.Ukongezelela, inxalenye yolwimi isesichengeni sokonakala, ngoko kufuneka kulumke xa kuhlanganisana, kuchithwa okanye kuthuthwe.Imiphezulu yokutywina yolwimi kunye negroove ilungele ukutsha, uqhushumbo, imidiya eyityhefu, kunye nezicelo ezinoxinzelelo oluphezulu.Nokuba nobukhulu obukhulu, basenokubonelela ngesitywina esisebenzayo xa uxinzelelo lungekho phezulu kakhulu.
4. I-Saky Steel Full Face (FF) kunyeRing Joint (RJ):
Ukutywinwa kobuso obugcweleyo kufanelekileyo kwizicelo zoxinzelelo oluphantsi (PN ≤ 1.6MPa).
Imiphezulu edibeneyo ye-ring isetyenziselwa ngokukodwa kwii-flanges ze-welded entanyeni kunye nee-flanges ezidibeneyo, ezifanelekileyo kwiindidi zoxinzelelo (6.3MPa ≤ PN ≤ 25.0MPa).
Ezinye Iindidi zoMphezulu wokutywina:
Kwiinqanawa zoxinzelelo oluphezulu kunye nemibhobho yoxinzelelo oluphezulu, iindawo zokutywinwa kwe-conical okanye iindawo zokutywinwa ze-trapezoidal groove zingasetyenziswa.Zidityaniswe nee-gaskets zetsimbi engqukuva (i-lens gaskets) kunye neegasket zetsimbi ezine-elliptical or octagonal cross-sections, ngokulandelanayo.Le miphezulu yokutywina ilungele ukusetyenziswa koxinzelelo oluphezulu kodwa ifuna ukuchaneka komgangatho ophezulu kunye nokugqitywa komphezulu, okwenza kube nzima kumatshini.
