U-Didier Vassal, iPhini Likamongameli we-OEM kanye Nezinsizakalo Zasemanzini e-Victaulic, uqhathanisa izindlela zokuxhuma amapayipi ane-flanged futhi agxilile futhi uchaza izinzuzo zokufakwa kwamapayipi agxunyekwe phezu kwama-flange.Izinhlelo zamapayipi ezisebenzayo zibalulekile kububanzi bezinsizakalo ezidingekayo ebhodini, okuhlanganisa nezinhlelo zesibili ezifana amasistimu we-bilge kanye ne-ballast, ukupholisa kwamanzi olwandle namanzi ahlanzekile, amafutha okugcoba, ukuvikelwa komlilo kanye nokuhlanza i-deck.Kulezi zinhlelo, lapho izinga lepayipi livumela, enye indlela ephumelelayo yokushisela / i-flanging iwukusetshenziswa kwamajoyinti emishini afakiwe anikeza uhla lwezobuchwepheshe, izinzuzo zezomnotho nezingokoqobo.Lokhu kufaka phakathi ukusebenza okuthuthukisiwe; ngokushesha, ukufakwa nokugcinwa okulula kanye nokugcinwa kwesisindo esincishisiwe.Izinkinga Zokusebenza Ekufakweni okune-flanged, ama-flange amabili okukhwelana ahlanganiswe ndawonye futhi acindezele ama-gaskets ukuze adale uphawu.Ngenxa yokuthi amabhawodi namantongomane amalunga ane-flanged amunca futhi anxephezele amandla esistimu, angakwazi ukwelula futhi alahlekelwa ukuqina kwawo kwasekuqaleni ngokuhamba kwesikhathi ngenxa yokuguquguquka kwengcindezi, ukucindezela kokusebenza kwesistimu, ukudlidliza, nokwanda nokuncipha kwezinga lokushisa.Lapho la mabhawodi ethola ukuphumula kwe-torque, i-gasket izolahlekelwa uphawu lwayo lokucindezela, okungaholela emazingeni ahlukene okuvuza. indawo kanye nomsebenzi wesistimu yamapayipi, ukuvuza kungabiza futhi kube yingozi, okuholela ekugcinweni / ukulungisa isikhathi sokuphumula kanye nobungozi.I-gasket izodinga ukushintshwa lapho i-joint ihlakazwa ngoba ngokuhamba kwesikhathi i-gasket izobophezela ebusweni be-flange.Lapho ihlakaza ukulinganisa, ama-gaskets adinga ukukhunyulwa kokubili kobuso be-flange, futhi lezi zindawo zidinga ukuhlanzwa ngaphambi kokufaka ama-gaskets, futhi ukwandisa isikhathi sokugcina ukulungiswa. , okungesinye isizathu sokuvuza.Idizayini yokufakwa kwemishini egobile inqoba lezi zinkinga zokusebenza.I-groove iqala ukwakhiwa ekugcineni kwepayipi, futhi uxhumano lwepayipi luvikelwa isixhumi esithatha i-elastomer gasket ekwazi ukumelana nokucindezela.I-coupling indlu izungeza i-gasket ngokuphelele, iqinisa isivalo futhi ibambe endaweni lapho ukuhlangana kuhileleke futhi idale ukuhlangana okuhle emgodini we-tube.Ubuchwepheshe bamuva bokuhlanganisa buvumela amapayipi afinyelela ku-24" (600mm) ububanzi ukuthi ahlanganiswe ngokugcwele amabili nje kuphela. amantongomane namabhawodi ukuze kuvikeleke amalunga azibambayo.Ijoyinti lomshini lidala uphawu oluphindwe kathathu ngenxa yobudlelwano bokuklama phakathi kwepayipi, i-gasket, kanye nezindlu, okuthuthukiswayo lapho uhlelo lucindezelwa.Ama-Couplings Aqinile futhi Aguquguqukayo Atholakala ngokuqinile futhi aguquguqukayo, ama-slotted mechanical couplings awuhlobo Lwenhlangano Yekilasi Oluvunyiwe futhi lungasetshenziswa esikhundleni sendlela ye-weld/flange ezinhlelweni ezingu-30 ngaphansi kwamazinga okufaka amiswe yi-ejensi ngayinye eqinisekisayo.Isibonelo, sebenzisa ama-coupling aqinile ezindaweni ezifana nama-manifold namavalvu, okulula ukuwenza. ukufinyelela nokushintsha ama-flange.Ngokuya ngemvelo yomklamo wawo, ukuhlanganisa okuqinile nakho kunikeza ukuqina kwe-axial kanye ne-radial okuqhathanisekayo kumajoyinti ane-flanged noma ashiselwe.Ngaphezu kokunyakaza kwamapayipi ngenxa yokwanda okushisayo noma ukudlidliza, ukuhlangana okuguquguqukayo kunezinzuzo ezinhlelweni zokusebenza lapho ukunyakaza okuhlobene. phakathi kwepayipi kanye nesakhiwo sokusekela kulindeleke.Ukunwetshwa nokufinyela kungabeka ingcindezi kuma-flange namapayipi, kulimaze ama-gaskets ngokuhamba kwesikhathi.Lapho lokhu kwenzeka, ilunga lisengozini yokuvuza.Ama-couplings aguquguqukayo avaliwe angakwazi ukuthwala ukugudluzwa kwamapayipi ngendlela ye-axial movement. noma ukuchezuka kwe-angular.Ngenxa yalesi sizathu, alungele ukufaka amapayipi amade, ikakhulukazi phakathi kwamabhulokhi olwandle oluvulekile lapho ama-flange angaxebuka ngokuhamba kwesikhathi, okuholela engcupheni yokuvuza nokuhlukaniswa kwamapayipi.Ukuxhuma okuqinile nokuguquguqukayo nakho kunikeza inzuzo yomsindo. kanye nokudambisa ukudlidliza, okuqeda isidingo sezingxenye ezikhethekile zokunciphisa umsindo kanye nezivunguvungu zenjoloba ezibolayo noma okufanayo.Ukusetshenziswa kwamasistimu amapayipi agxunyekwe ngomshini kungasheshisa futhi kwenze kube lula ukufakwa nokunakekelwa, futhi kwandise ukusebenza kahle kwamasistimu amapayipi ebhodini.Ukufakwa kalula kokufakwa ekuqaleni ukufakwa, izimbobo zebhawodi ze-flange kufanele ziqondaniswe ngokunembile bese ziqiniswa ukuze kuvikeleke i-joint.Izikhombo zembobo yebholidi endaweni yokungena kanye ne-outlet kufanele futhi ihambisane ngokuphelele nama-flange emapayipini azoxhunywa kumshini. inombolo yezimbobo ku-flange inquma kuphela esinye sezimo eziningi zokulungisa, i-fitting kuphela noma i-valve ingashintshwa ukuze ifane nezimbobo ze-bolt.Ngaphezu kwalokho, omunye umkhawulo wepayipi eline-flanged kufanele futhi uhambisane ne-flange yayo yokuhlangana, eyanda ngokuqhubekayo. ubunzima bokuhlanganisa kanye nengozi yokungaqondani kahle.Amasistimu wamapayipi akhulisiwe awanayo le nkinga, futhi avumela ukufakwa kalula, ngokuzungezisa amapayipi angu-360-degree kanye nezingxenye zokukhwelana.Ngaphandle kwephethini yembobo yebhawodi ukuze ibekwe umugqa, ukuhlanganisa kungabekwa noma yikuphi lapho okuhlanganyelwe khona.Ama-couplings angazungeziswa eduze kwepayipi ukuze kube lula ukubhowuntiswa nokwenza lula ukufinyelela kumishini.Ngaphezu kokususa ukungaboni ngasolinye phakathi nokufakwa, amandla okuhlanganisa angama-degree angu-360, kanye nephrofayili yakho encane uma kuqhathaniswa nama-flange, kwenza ukufakwa kwesistimu oku-grooved. ilungele izindawo ezimpintshana.Ukwengeza, izifaki zingathola wonke amabhawodi omhlangano endaweni eyodwa ukuze kuhlolwe futhi kulungiswe uhlelo kalula.Ama-flange acishe abe kabili ububanzi bangaphandle bamapayipi axhumeka kuwo.Ngokujwayelekile, ukuhlanganisa okuboshiwe yingxenye yalokhu. ubukhulu.Inzuzo yosayizi wedizayini encane yenza isistimu yemisele ibe ilungele imisebenzi lapho isikhala silinganiselwe, njengokungena kwedekhi nodonga - iqiniso elaqashelwa emuva ngeminyaka yawo-1930s lapho ama-Victaulic couplings asetshenziswa okokuqala emagcekeni emikhumbi aseBrithani.Assembly Speed ​​​Ipayipi eligoqiwe lingafakwa ngokushesha kakhulu kune-flanged ngoba ukuhlanganisa kunamabhawudi ambalwa futhi izidingo ze-torque azidluli ku-12" (300mm). Ngokungafani nama-flange okumelwe ashiselwe emaphethelweni epayipi, amapayipi agxiliwe Ukuhlanganiswa kwe-valve akudingi ukushisela, okuqhubeka kunciphisa isikhathi sokufaka futhi kuqede umonakalo ongase ube khona oshisayo ku-valve, kuyilapho futhi kunciphisa izingozi zokuphepha ngokuqeda umsebenzi oshisayo. I-DIN 150 ye-ballast efakwe ngemikhiqizo ye-Victaulic grooved Ukuqhathaniswa kwezintambo nezindlela zokuxhuma zendabuko kubonise ukwehla okungama-66% esiphelele sesikhathi sokufakwa esidingekayo (amahora angu-150.47 aqhathaniswa namahora omuntu angu-443.16). Ukufakwa kwama-slip flange angama-52 kanye nezindololwane ezishiselwe nezinsika uma kuqhathaniswa nama-couplings aqinile angama-60 Isikhathi esidingekayo sibonisa umehluko omkhulu kakhulu ngesikhathi. Ama-couplings adinga amabhawodi amabili kuphela afika kusayizi wamapayipi angu-24" (600 mm). Ngokuphambene, ama-flange adinga okungenani amasethi angu-20 amantongomane nama-Bolts. Ngaphezu kwalokho, ama-flange adinga ukuqiniswa kwenkanyezi okuchitha isikhathi ngesikrufu esikhethekile ukuze kukale futhi kuqinisekiswe okulungile. Ukucaciswa kwe-torque kufinyelelwa. Ubuchwepheshe be-grooved tube buvumela ukuhlanganisa ukuthi kuhlanganiswe kusetshenziswa amathuluzi ajwayelekile wezandla, uma indlu yokuhlanganisa isihlanganisiwe Amaphedi e-bolt axhumene nensimbi futhi ilunga lilingana ngendlela efanele. Ngakolunye uhlangothi, ama-Flanges awanikezi isiqinisekiso esibonakalayo: okuwukuphela kwendlela yokuqinisekisa ukuhlangana okulungile uhlelo lokugcwalisa nokucindezela, hlola Ukuvuza futhi uqinise amalunga njengoba kudingeka Izakhiwo ezifanayo zezinhlelo zamapayipi ane-grooved ezisheshisa ukufakwa-amabhawodi ambalwa futhi cha Izidingo ze-torque—futhi zenza ukugcinwa kwesistimu noma ukubuyisela kabusha kube umsebenzi osheshayo futhi olula, Ukuze uthole ukufinyelela empompini noma ku-valve, khulula amabhawodi amabili okuhlanganisa futhi ukhiphe indlu kanye ne-gasket ekuhlanganyeleni. Kusistimu ene-flanged, amabhawodi amaningi adinga ukususwa. Lapho uhlanganisa kabusha i-flange, nayo iyadingeka ekufakweni kokuqala Inqubo efanayo yokuqinisa ibhawudo edla isikhathi yenziwa ku-The shaft coupling ibamba i-gasket ngokucindezelwa okunembile kusuka ngaphandle kokufaka. Ukwengeza, njengoba i-gasket yokuhlanganisa ingekho ngaphansi kwamandla aphezulu okucindezela, ukugcinwa okuvamile akudingeki, kuyilapho i-flange gasket idinga ukushintshwa lapho uhlelo luhlakazwa ukuze lugcinwe. Ukuze unciphise umsindo wesistimu nokudlidliza, amasistimu ane-flanged adinga ukuvuthela kwerabha noma ipayipi elilukiweyo. Lezi zingxenye zingehluleka ngenxa yokwelulelwa ngokweqile futhi, ngaphansi kokuguga nokudabuka, zidinga ukushintshwa ngokwesilinganiso njalo eminyakeni eyi-10, okuholela ezindlekweni nesikhathi sokungasebenzi kwesistimu. Kodwa-ke, amalunga epayipi afakwe ngomshini anganweba impilo yohlelo. Ikhono labo lokwamukela ukudlidliza kwesistimu linciphisa ingozi yokuhluleka okuhlangene ngaphandle kwesidingo semikhiqizo ekhethekile edinga ukulungiswa njalo noma ukushintshwa. Kufakwe ekuhlanganisweni okuguquguqukayo nokuqinile Ama-elastomeric gasket ahlala isikhathi eside kakhulu futhi angamelana nezingcindezi ezinkulu zokusebenza kanye nemithwalo yama-cyclic. Uhlelo lungacindezelwa ngokuphindaphindiwe futhi lucindezeleke ngaphandle kokukhathala ku-elastomer gasket. Ama-valve okusiza isisindo ngokuvamile akhiwa ezingxenyeni ezine-flanged. Nokho, lokhu Indlela yokuxhuma ingangeza isisindo esingadingekile ohlelweni lwamapayipi. I-valve ene-6Intshi (150 mm) ene-valve ene-flanged iqukethe i-valve butterfly ye-lug exhunywe nge-butt weld flange namabhawudi ayisishiyagalombili namantongomane ohlangothini ngalunye lwevalvu futhi inesisindo esingamaphawundi angu-85. Ukuhlanganisa i-valve engu-6" (150 mm) kusebenzisa i-valve Ivalve yevemvane eyi-grooved end grooved end kanye nama couplings amabili aqinile ukuze kuxhunywe umhlangano futhi inesisindo esingama lbs angu-35, ilula ngo-58% kune-flanged assembly.Ngakho-ke, ama-valve ahlanganisiwe ayindawo ekahle yemboni yokwakha umkhumbi.I-ballast ye-DIN engu-150 engenhla ifakiwe. ukuqhathaniswa kwentambo kubonisa ukuncishiswa kwesisindo ngo-30% (2,164 lbs vs. 3,115 lbs) lapho kusetshenziswa imikhiqizo ye-Victaulic grooved esikhundleni sezindlela zokuxhuma zendabuko.Ama-flange anezidleke angama-52, amasethi webhawodi namawasha uma kuqhathaniswa nama-coupling angu-60 aqinile yisizathu esiyinhloko sesisindo esikhulayo uhlelo olushiselwe/ olune-flanged.Ukonga isisindo ngokusebenzisa izifakelo ezifakwe slotted esikhundleni samaflange kungafezwa ngobukhulu obuhlukahlukene bobukhulu bamapayipi.Ubukhulu bokunciphisa buncike kububanzi bepayipi kanye nohlobo lokufakela okusetshenzisiwe.Ezivivinyweni kusetshenziswa Isitayela esisodwa se-Victaulic 77 ukuhlanganisa, ukuhlanganisa okunzima kakhulu ochungechungeni, ukuxhuma ipayipi, isisindo esiphelele esifakiwe somhlangano we-grooved sancishiswa kakhulu uma kuqhathaniswa nama-slip flanges amabili okukhanya we-PN10. Amarekhodi okulahlekelwa isisindo kanje: 4 "(100mm) - 67% ; 12” (300mm) – 54%; 20” (500mm) – 60.5%. Sebenzisa i-lighterweight flexible Type 75 noma i-Rigid Type 07 couplings kanye/noma izinhlobo ze-flange Ezisindayo ezingafinyelela kalula ukonga isisindo esingu-70%. Isibonelo, i-flange engu-24" (600 mm) esethi yesistimu ye-TG2 inesisindo esingu-507 lbs, kodwa ukuhlanganiswa okufanayo kusetshenziswa okokufakwa kwe-Victaulic kunesisindo esingama-lbs angu-88 kuphela.
