Zeziphi iindlela eziqhelekileyo zokutywinwa komphezulu weflange?

1. Ubuso obugcweleyo (FF):
I-flange inomphezulu ogudileyo, isakhiwo esilula, kunye nokusebenza kakuhle.Ingasetyenziselwa kwiimeko apho uxinzelelo aluphezulu okanye izinga lokushisa alikho phezulu.Nangona kunjalo, indawo yoqhagamshelwano phakathi kwendawo yokutywina kunye ne-gasket inkulu, ifuna amandla amakhulu oxinzelelo.Ngethuba lokufakela, i-gasket ayifanele ibekwe, kwaye emva kokuqina kwangaphambili, i-gasket kulula ukwandisa okanye ukuhamba kumacala omabini.Xa usebenzisa i-lined flanges okanye i-non-metallic flanges, i-Flange ye-surface ye-FF iqinisekisa ukuba indawo yokutywina ayiphuli ngexesha lokuqinisa, ngakumbi indawo ye-FF.

2 Ubuso obuphakanyisiweyo (RF):
Inesakhiwo esilula kunye nokusebenza kakuhle, kwaye ingasetyenziselwa kwiimeko apho uxinzelelo aluphezulu kakhulu okanye izinga lokushisa aliphezulu kakhulu.Nangona kunjalo, abanye abantu bakholelwa ukuba ukusebenzisa i-gaskets phantsi koxinzelelo oluphezulu kunokwenzeka.
Ngenxa yofakelo lwayo olulula, le flange yindlela esetyenziswa ngokubanzi yokutywina engaphantsi kwe-PN 150.

3. Ubuso bobudoda nobasetyhini (MFM):
Ukubandakanya i-concave kunye ne-convex surfaces, i-gasket ifakwe kwi-concave surface.Xa kuthelekiswa neeflange ezisicaba, iigasket zeconcave convex flange azithandeki kangako kuxinzelelo, kulula ukudityaniswa, kwaye zinoluhlu olukhulu loxinzelelo olusebenzayo kuneiiflange ezisicaba, okwenza ukuba bafanelekele iimfuno ezingqongqo zokutywinwa.Nangona kunjalo, kwizixhobo ezinokushisa okuphezulu okusebenzayo kunye needamitha ezinkulu zokutywina, abanye abantu bakholelwa ukuba i-gasket isenokuthi ikhutshwe xa isebenzisa le ndawo yokutywina.

4. Ulwimi lobuso beflange (TG)
Indlela ye-mortise groove flange iquka i-groove surface kunye ne-groove surface, kwaye i-gasket ifakwe kwi-groove.Njenge-concave kunye ne-convex flanges, i-tenon kunye ne-groove flanges ayicinezeli kwi-grooves, ngoko ke indawo yabo yoxinzelelo incinci kwaye i-gasket igxininiswe ngokulinganayo.Ngenxa yokuba akukho nxibelelwano oluthe ngqo phakathi kwe-gasket kunye ne-medium, i-medium inefuthe elincinci kwi-corrosion kunye noxinzelelo lwe-flange yokutywinwa kwendawo.Ngoko ke, isoloko isetyenziswa kwiimeko ezineemfuno zokutywinwa ezingqongqo zoxinzelelo oluphezulu, olunokutsha, oluqhumayo, lweendaba ezinetyhefu, njl.njl. Le gasket yomphezulu wokutywina ilula kwaye inenzuzo ngexesha lofakelo, kodwa ukusetyenzwa kwayo kunye nokutshintshwa kuya kuba nzima ngakumbi.

5. Ring Ubuso obudibeneyo (RJ)
I-flange yokutywina i-gasket yomhlaba ifakwe kwi-groove ye-annular.Beka i-gasket kwi-groove ye-ring ukwenzela ukuba ingacinezeli kwi-groove, kunye nommandla omncinci wokunyanzeliswa kunye namandla afanayo kwi-gasket.Ngenxa yokuba akukho nxibelelwano oluthe ngqo phakathi kwe-gasket kunye ne-medium, i-medium inefuthe elincinci kwi-corrosion kunye noxinzelelo lwe-flange yokutywinwa kwendawo.Ke ngoko, ihlala isetyenziswa kwiimeko ezineemfuno ezingqongqo zokutywinwa koxinzelelo oluphezulu, olunokutsha, oluqhumayo, imidiya enetyhefu, njl.
Isishwankathelo, iifom zokutywinwa komphezulu we-flanges zihlukile, kwaye iimpawu zabo kunye noluhlu lwezicelo lukwahluke.Ngoko ke, xa ukhetha i-flange, kufuneka sinikele ingqalelo ekusebenziseni kwayo kunye neemfuno zokusebenza.Umzekelo, xa umsebenzi ungekho ngqwabalala, khetha iUmphezulu wokutywina weRF, kwaye xa iimeko zokusebenza zinzima, khetha indawo yokutywina ye-RJ ehlangabezana ngokupheleleyo neemfuno zokutywinwa;Kungcono ukusebenzisa umphezulu we-FF kwimibhobho engeyiyo eyentsimbi okanye efakwe iflange yoxinzelelo oluphantsi.Imeko ethile ixhomekeke kwiimfuno zangempela.
