Li-flanges, le hoja hangata li hlokomolohuoa, li phetha karolo ea bohlokoa liindastering tse fapa-fapaneng tse kenyeletsang tlhahiso, kaho le boenjiniere.Likarolo tsena tsa bohlokoa li sebelisetsoa ho hokahanya le ho boloka likarolo tse fapaneng hammoho, ho fana ka botsitso le ho netefatsa katleho ea litsamaiso.Empa hantle-ntle flange ke eng?Tataisong ena e felletseng, re tla hlahloba litšoaneleho tsa mefuta e fapaneng ea li-flanges le ho hlahloba mesebetsi ea tsona, lits'ebetso, le bohlokoa ba masoba a tsona bakeng sa ho kenya.
Ho utloisisa Flanges:
Li-flange, tse tsoang lentsoeng 'flange', li bolela likarolo tse nang le moqomo kapa molomo o phahamisitsoeng bakeng sa matla a eketsehileng, botsitso le ho khomarela habonolo.Li tla ka libopeho le boholo bo fapaneng, ho itšetlehile ka morero oa tsona le thepa eo li entsoeng ka eona.Le hoja li-flange tse ling e le likarolo tse ikemetseng, tse ling ke mefuta e kopantsoeng, e kang liphaephe tse nang le li-flange ka lehlakoreng le le leng kapa ka bobeli.Likarolo tsena tse feto-fetohang li ka fumaneha lits'ebetsong tse fapaneng, joalo ka liphaephe, lipompo, li-valve le li-turbine.
Litšobotsi tsa mefuta e fapaneng ea li-flanges:
1. Weld Neck Flanges:
Li-weld neck flanges li tsebahala ka li-hubs tsa tsona tse telele, tse nang le tepe tse kopanang butle-butle le phala.Li-flange tsena li fana ka ts'ebetso e ntle ea phallo ea mokelikeli le kabo ea khatello ea maikutlo, e li etsang hore li tšoanelehe bakeng sa lits'ebetso tsa khatello e phahameng le mocheso o phahameng.Molala oa welding o fana ka matla a eketsehileng le tšehetso, ho netefatsa hore ho na le khokahanyo e sireletsehileng le e sa lutleng.E sebelisoa haholo indastering ea petrochemical le oli, li-weld neck flanges li tumme ka lebaka la ts'ebetso ea tsona e phahameng le ho tšoarella nako e telele.
2. Li-Slip-On Flanges:
Li-slip-on flanges ke mofuta o tloaelehileng ka ho fetisisa oa li-flange, tse tsejoang ka ho kenya habonolo le tlhaho e theko e tlaase.Li-flange tsena li theoleloa holim'a phala ebe li chesetsoa ka mahlakoreng ka bobeli ho tiisa hore li lula sebakeng seo.Li-slip-on flanges li fana ka maemo le boiketlo ba ho tsamaisana, ho etsa hore li tšoanelehe bakeng sa lits'ebetso tsa khatello e tlase.Hangata li sebelisoa liindastering tse kang phepelo ea metsi, lipeipi tsa metsi le tsamaiso ea nosetso.
3. Blind Flanges:
Li-flange tse foufetseng, joalokaha lebitso le bolela, li sebelisetsoa ho koala ntlha ea phala ha e sa sebelisoe.Li-flange tsena li tiile ha li na masoba, li fana ka ho itšehla thajana ka ho feletseng le ho thibela ho phalla ha lintho.Li-blind flanges li bohlokoa lits'ebetsong moo liphaephe li hlokang ho koaloa ka nakoana kapa moo ho hlokahalang ho fihlella habonolo bakeng sa tlhokomelo.Ho phaella moo, li-flange tse foufetseng li ka ba le sefahleho se phahamisitsoeng kapa sefahleho se bataletseng, ho itšetlehile ka litlhoko tsa bona tse khethehileng.
4. Socket Weld Flanges:
Li-socket weld flanges li tšoana le li-slip-on flanges empa li na le sokete kapa bore ka lehlakoreng le ka hare ho lumella ho kenngoa ha pipe.Li-flange tsena li sebelisoa haholo-holo bakeng sa boholo ba liphaephe tse nyane le litsamaiso tse phahameng tsa khatello.Ka ho tjheseletsa phala ka soketeng, li-socket weld flanges li fana ka tiiso e tšepahalang le ts'ebetso e nepahetseng ea phallo.Hangata li sebelisoa lifemeng tse sebetsanang le lik'hemik'hale, liindasteri tsa petrochemical, le lits'ebetso tse ling moo thibelo ea ho lutla e leng bohlokoa.
Bohlokoa ba Flange Through-Holes:
Li-flange li hlaha ka masoba bakeng sa ho kenya li-screws, liboutu kapa lithupa ho li hokela ka mokhoa o sireletsehileng ho likarolo tse ling.Likoti tsena li bapala karolo ea bohlokoa ho boloka botsitso le bots'epehi ba sistimi.Ka ho hokahanya le ho tiisa li-flange hantle, kotsi ea ho lutla, ho robeha, le ho hloleha ha sistimi ka kakaretso e fokotsehile haholo.Ntle le moo, likoti li etsa hore ho be bonolo ho qhaqha bakeng sa tlhokomelo, ho hloekisa, kapa ho fetola likarolo, ho ntlafatsa ts'ebetso le bophelo bo bolelele ba sistimi.
Qetello:
Ho utloisisa litšobotsi le mefuta ea li-flange ho bohlokoa bakeng sa ho netefatsa ts'ebetso e nepahetseng ea litsamaiso liindastering tse fapaneng.Ebang ke li-weld neck flanges bakeng sa lisebelisoa tsa khatello e phahameng, li-slip-on flanges bakeng sa ho boloka litšenyehelo, kapa li-flange tse foufetseng bakeng sa ho koaloa ha nakoana, mofuta o mong le o mong o sebeletsa merero e fapaneng.Likoti tse holim'a li-flange li lumella ho khomarela ka mokhoa o sireletsehileng le ho lokisoa habonolo, ho theha tsamaiso e tšepahalang le e sebetsang hantle.Ha u ntse u kenella ka hare ho lefats'e la li-flanges, u tla ba le kananelo e kholoanyane bakeng sa likarolo tsena tseo hangata li hlokomolohuoang le phello ea tsona ts'ebetsong e se nang moeli ea lits'ebetso tse ngata tsa indasteri.
