Ubuso beFlange

Yintoni ubuso beFlange?

Iindidi ezahlukeneyo zobuso be-flange zisetyenziswa njengeendawo zokunxibelelana ukuhlalisa imathiriyeli ye-gasket yokutywina. I-ASME B16.5 kunye ne-B16.47 zichaza iintlobo ngeentlobo zeeflange ezijongene nazo, kubandakanywa ubuso obuphakanyisiweyo, iinkunzi ezinkulu ezijongene nenkunzi nemazi ezinobukhulu obufanayo ukunika indawo yoqhagamshelwano enkulu.

Ezinye iiflange ezijongene nazo ezigqunywe yile migangatho ziquka i-faces enkulu kunye nencinci yolwimi kunye ne-groove, kunye nekhonkco elidibeneyo elijongene ngokukodwa lentsimbi yohlobo lwentsimbi.

Ubuso obuphakanyisiweyo (RF)

I-Face Face flange yolona hlobo luqhelekileyo olusetyenziswa kwinkqubo yokusetyenziswa kwezityalo, 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).

Ukuphakama kobuso obuphakanyisiweyo

Kwimilinganiselo yokuphakama H kunye no-B yazo zonke imilinganiselo echazwe kwiiflange kule webhusayithi, ngaphandle kweLap Joint flange, kubalulekile ukuqonda nokukhumbula oku kulandelayo:

Kwiiklasi zoxinzelelo lwe-150 kunye ne-300, ukuphakama kobuso obuphakanyisiweyo malunga ne-1.6 mm (1/16 intshi). Kwezi klasi zimbini zoxinzelelo, phantse bonke ababoneleli beeflange, babonisa kwikhathalogu okanye incwadana yabo, imilinganiselo ye-H kunye ne-B kuquka ukuphakama kobuso obuphakanyisiweyo. ((Umfanekiso 1))

Kwiiklasi zoxinzelelo ze-400, 600, 900, 1500 kunye ne-2500, ukuphakama kobuso obuphakanyisiweyo malunga ne-6.4 mm (1/4 intshi). Kwezi klasi zoxinzelelo, uninzi lwababoneleli babonisa imilinganiselo ye-H kunye ne-B ngaphandle kokuphakama kobuso obuphakanyisiweyo. (Umfanekiso 2)

Ubuso obuMcaba (FF)

I-Flat Face flange inomphezulu we-gasket kwinqwelomoya efanayo nobuso besangqa se-bolting. Usetyenziso olusebenzisa iiflange zobuso ezisicaba zikholisa ukuba zezo apho i-mating flange okanye i-flanged fitting yenziwe ngokuphosa.

Iiflange zobuso obucaba azinakuze zibotshwe kwiflange yobuso obunyusiweyo. I-ASME B31.1 ithi xa udibanisa iiflange zentsimbi eziphose ngobuso kwiintsimbi zekhabhoni, ubuso obuphakanyisiweyo kwiflange yentsimbi yekhabhoni kufuneka bususwe, kwaye kufuneka igasket yobuso obugcweleyo. Oku kukugcina i-flange yentsimbi ebhityileyo, encinci yentsimbi ukuba ingaphumi kwisithuba esibangelwa bubuso obuphakanyisiweyo be-carbon steel flange.

Isidibanisi soNxibelelwano (RTJ)

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.

Ring Uhlobo Joint gaskets

I-Ring Type Joint gaskets yintsimbi yokutywina imisesane, ifanelekile kwizicelo zoxinzelelo oluphezulu kunye nobushushu obuphezulu. Zihlala zisetyenziselwa kwiiflange ezikhethekileyo, ezikhaphayo eziqinisekisa ukutywinwa okulungileyo, okuthembekileyo kunye nokukhetha okuchanekileyo kweeprofayili kunye nezinto eziphathekayo.

I-Ring Type Joint gaskets ziyilelwe ukutywina "ngoqhagamshelwano lomgca wokuqala" okanye isenzo somtshato phakathi kweflange yokukhwelana kunye ne-gasket. Ngokufaka uxinzelelo kwi-interface yetywina ngokusebenzisa amandla ebholiti, isinyithi "esithambileyo" se-gasket sigeleza kwisakhiwo se-microfine sezinto ezilukhuni ze-flange, kunye nokudala itywina eliqina kakhulu nelisebenzayo.

Uninzi olusetyenziswayo sisitayileRiringi eyenziwe ngokuhambelana ne-ASME B16.20 esetyenziswa kunye ne-ASME B16.5 flanges, iklasi 150 ukuya ku-2500. Isimbo 'R' sokudityaniswa kohlobo lweringi senziwa kuzo zombini ulungelelwaniso olumbhoxo kunye nolweoctagonal.

IOctagonalUmsesane unomsebenzi wokutywina ophezulu ngakumbi kune-oval kwaye iya kuba yeyona gasket ekhethwayo. Nangona kunjalo, kuphela icandelo lomnqamlezo oval elinokuthi lisetyenziswe kuhlobo oludala lwe-groove esezantsi. Uyilo olutsha olusezantsi lwegroove luya kwamkela nokuba yi-oval okanye icandelo lomnqamlezo octagonal.

Uhlobo lwe-R ring joints luyilelwe ukutywina uxinzelelo ukuya kuthi ga kwi-6,250 psi ngokuhambelana ne-ASME B16.5 yoxinzelelo kunye nokuya kuthi ga kwi-5,000 psi.

Uxinzelelo lwenkqubo ephezulu lubangela uxinzelelo oluphezulu lomphezulu. Uhlobo lwe-RX luyatshintsheka kunye neemodeli ezisemgangathweni ze-R.

IBXuhlobo lufanelekile kuxinzelelo oluphezulu kakhulu ukuya kuthi ga kwi-1500 bar. Lo mdibaniso weringi awutshintshi kunye nezinye iindidi, kwaye ulungele kuphela uhlobo lwe-API ye-BX flanges kunye ne-grooves.

Umphezulu wokutywina kwiigrooves ezidityanisiweyo kufuneka zigqitywe ngokutyibilikayo ukuya kutsho kuma-Microinches angama-63 kwaye zingabi nazingxobo ezichasayo, izixhobo okanye amanqaku okuncokola. Batywina ngoqhagamshelwano lomgca wokuqala okanye isenzo sokutshata njengoko amandla oxinzelelo asetyenziswa. Ubunzima bendandatho kufuneka buhlale bungaphantsi kobunzima beeflange.

Ukukhetha izinto eziphathekayo

Itheyibhile engezantsi ibonisa ezona zinto zisetyenziswa ngokuqhelekileyo kumalungu odidi lweringi.

Ulwimi kunye neGroove (T&G)

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 womatshini.

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.

Indoda kunye-noMfazi (M&F)

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; IiFlange zeM&F ezincinci kunye neeFlanges ezinkulu zeM&F. Ubuso obuqhelekileyo bamadoda nabasetyhini buhlala bufumaneka kwiqokobhe le-Heat Exchanger kwitshaneli kunye nokugquma iiflange.

Izinto eziluncedo kunye nokungalunganga kwe-T&G kunye nobuso be-M&F flange

Iingenelo
Iipropati ezingcono zokutywina, indawo echane ngakumbi kunye nokunyanzeliswa kwemathiriyeli yokutywina, ukusetyenziswa kolunye, ukutywina okufanelekileyo kunye nemathiriyeli yokutywina eyenziwe nge-spezialized (O-rings).

Iingxaki
Ukufumaneka korhwebo kunye neendleko. Ubuso obuqhelekileyo obuphakanyisiweyo buqheleke kakhulu kwaye bulungele ukufumaneka zombini malunga neeValve, iiflange kunye nemathiriyeli yokutywina. Enye into entsokothileyo kukuba eminye imithetho engqongqo kufuneka isetyenziswe kuyilo lwemibhobho. Ngaba uyala iiValve ukuba zibe zisiphelo sabasetyhini kumacala omabini, okanye kwelinye icala mhlawumbi, apho ukhomba zonke iziphelo zamadoda kwicala lokuhamba, okanye yintoni. Okufanayo kuyasebenza nakuluphi na udibaniso olujikekileyo lwejoyinti / inqanawa.
