RF - Ubuso obuphakanyisiweyo

I-flange yobuso obuphakanyisiweyo lolona hlobo luqhelekileyo olusetyenziswa kwizicelo zezityalo zenkqubo, kwaye kulula ukuchonga. Kubhekiswa kubo njengobuso obuphakanyisiweyo kuba imiphezulu ye-gasket iphakanyiswe ngaphezulu kobuso besangqa esibolingiweyo. Olu hlobo lobuso luvumela ukusetyenziswa kwendibaniselwano ebanzi yoyilo lwe-gasket, kubandakanywa neentlobo zeshiti elisicaba kunye ne-metallic composites ezifana nenxeba elijikelezayo kunye neentlobo ezimbini zebhatyi.

Injongo ye-RF flange kukugxila ngakumbi kuxinzelelo kwindawo encinci ye-gasket kwaye ngoko konyusa amandla okulawula uxinzelelo kwijoyinti. Ububanzi kunye nobude bukwi-ASME B16.5 echazwe, ngeklasi yoxinzelelo kunye nobubanzi. Ukulinganiswa koxinzelelo lweflange kumisela ukuphakama kobuso obuphakanyisiweyo.

Ukugqitywa kobuso beflange eqhelekileyo ye-ASME B16.5 RF flanges yi-125 ukuya kuma-250 µin Ra (3 ukuya kwi-6 µm Ra).

M - Ubuso bobudoda

FM- Ubuso bomfazi

Ngolu hlobo iiflange nazo kufuneka zihambelane. Ubuso beflange obunye bunommandla ophumela ngaphaya kobuso obuqhelekileyo beflange (Indoda). Enye iflange okanye i-mating flange inokudakumba okuhambelanayo (Owasetyhini) owenziwe ebusweni bayo.
Ubuso bemazi bubunzulu obuyi-3/16-intshi, ubuso bendoda bubude obuyi-1/4-intshi, kwaye zombini zigqibelele kakuhle. Idayamitha yangaphandle yobuso bemazi isebenza ukufumana kunye nokugcina i-gasket. Ngokomgaqo-2 iinguqulelo ziyafumaneka; iiFlanges zeM&F ezincinci kunye neeFlange ezinkulu zeM&F. Ubuso obuqhelekileyo bamadoda nabasetyhini buhlala bufumaneka kwiqokobhe le-Heat Exchanger kwitshaneli kunye nokugquma iiflange.

T - Ubuso bolwimi

Ubuso beG-Groove

Ubuso beTongue kunye neGroove zale flanges kufuneka zihambelane. Ubuso obunye beflange buneringi ephakanyisiweyo (ulwimi) olufakwe kwiflange yobuso ngelixa iflange yokukhwelana inokudakumba okuhambelanayo (iGroove) efakwe ebusweni bayo.

Iilwimi kunye ne-groove faces zisemgangathweni kuzo zombini iindidi ezinkulu kunye ezincinci. Bahluke kwindoda kunye nebhinqa ukuba i-diameters yangaphakathi yolwimi kunye ne-groove ayidluli kwisiseko se-flange, ngaloo ndlela igcina i-gasket kwi-diameter yayo yangaphakathi nangaphandle. Ezi zixhaphake ukufunyanwa kwiimpompo zokuvala kunye neeBonethi zeValve.

Amalungu olwimi kunye ne-groove anenzuzo kuba ayazilungelelanisa kwaye asebenze njengovimba wokunamathela. Umdibaniso wesikhafu ugcina i-axis yokulayisha ngokuhambelana nokudibanisa kwaye ayifuni umsebenzi omkhulu wokulungisa.

Ubuso beflange ngokubanzi obufana ne-RTJ, i-TandG kunye ne-FandM ayinakuze zidityaniswe kunye. Isizathu salokhu kukuba iindawo zoqhagamshelwano azifani kwaye akukho gasket enolunye uhlobo kwelinye icala kunye nolunye uhlobo kwelinye icala.

I-RTJ (RJ) -I-Ring Type Joint Face

I-Ring Type Joint flanges isetyenziswa ngokuqhelekileyo kuxinzelelo oluphezulu (iKlasi ye-600 kunye nokulinganisa okuphezulu) kunye / okanye iinkonzo zokushisa eziphezulu ngaphezu kwe-800 ° F (427 ° C). Banegrooves esike ebusweni babo apho intsimbi ring gaskets. I-flanges itywina xa iibholiti ziqinisiwe zicinezela i-gasket phakathi kwee-flanges kwi-grooves, i-deforming (okanye i-Coining) i-gasket ukwenza uqhagamshelwano olusondeleyo ngaphakathi kwi-grooves, ukudala intsimbi yokutywina isinyithi.

I-RTJ flange inokuba nobuso obuphakanyisiweyo kunye ne-ring groove efakwe kuyo. Lo buso buphakanyisiweyo abusebenzi njengenxalenye yeendlela zokutywina. Kwiiflange ze-RTJ ezitywinwa ngee-gaskets zeringi, ubuso obuphakanyisiweyo beeflange ezidityanisiweyo kunye neziqinisiweyo zinokudibana. Kule meko i-gasket ecinezelweyo ayiyi kuthwala umthwalo owongezelelweyo ngaphaya koxinzelelo lwe-bolt, ukungcangcazela kunye nokunyakaza akukwazi ukutyumza ngakumbi i-gasket kunye nokunciphisa uxhulumaniso lokudibanisa.
