IVictaulic OEM kunye neSekela Mongameli weeNkonzo zaseLwandle uDidier Vassal wathelekisa iindlela ezidityanisiweyo zeflange kunye negrooved umbhobho kwaye wachaza iingenelo zokudityaniswa kwemibhobho egrunjiweyo ngaphezulu kweeflange. Iinkqubo zombhobho ezisebenzayo ziyimfuneko kwiinkonzo ezininzi ezifunekayo kwiinqanawa, kubandakanywa iinkqubo zesibini ezifana ne-bilge kunye ne-ballast systems, ukupholisa ulwandle kunye namanzi amatsha, ioli yokuthambisa, ukukhuselwa komlilo kunye nokucoca i-deck. Kwezi nkqubo, apho umgangatho wemibhobho uvumela, enye indlela yokudibanisa umbhobho esebenzayo kwi-welding / flanging kukusetyenziswa kwee-slotted mechanical joints, ezibonelela ngoluhlu lweenzuzo zobugcisa, ezoqoqosho kunye nokusebenza. Oku kubandakanya ukusebenza okuphuculweyo; ngokukhawuleza kwaye kulula ukufakela kunye nokugcinwa kunye nokunciphisa ubunzima ebhodini. Imiba yokuSebenza Kumalungu emibhobho e-flanged, iiflange ezimbini zokukhwelana zibotshwe kunye kwaye i-gasket ixinzelelwe ukwenza itywina. Njengoko iibholiti kunye namantongomane edibeneyo yeflange ifunxa kwaye ihlawule amandla enkqubo, ngokuhamba kwexesha, iibholiti kunye namantongomane ziya kolula kwaye ziphulukane noxinzelelo lwazo lwangaphambili ngenxa yokuguquguquka koxinzelelo, uxinzelelo olusebenzayo lwenkqubo, ukungcangcazela, kunye nokwandiswa kwe-thermal kunye nokuncipha. Xa ezi bholiti zifumana ukuphumla kwetorque, i-gasket iya kuphulukana netywina layo lokucinezela, elinokukhokelela kumanqanaba ahlukeneyo okuvuza. Ngokuxhomekeke kwindawo kunye nomsebenzi wenkqubo yemibhobho, ukuvuza kunokuba yindleko kwaye kuyingozi, okukhokelela ekugcinweni / ukulungiswa kwexesha lokunciphisa kunye nobungozi. I-gasket idinga ukutshintshwa xa udibanisa umdibaniselwano, kuba ekuhambeni kwexesha, i-gasket iya kubambelela kwi-flange surface. Xa udibanisa i-joint, i-gaskets kufuneka ikhutshwe kwiindawo ezimbini ze-flange, kwaye le mimandla kufuneka ihlambuluke ngaphambi kokuba ithathe indawo ye-gaskets, iphinde ikhulise ixesha lokulondoloza. Ngenxa yamandla oqhagamshelwano lwebholiti kunye nokwandiswa kunye nokucutheka kwenkqubo, i-gasket ye-flange nayo iya kuvelisa i-compression "deformation" ngokuhamba kwexesha, enye into ebangela ukuvuza. Uyilo lwemibhobho edibeneyo yomatshini efakwe kuyo yoyisa ezi ngxaki zokusebenza. Okokuqala, i-groove yenziwe ekupheleni kombhobho, kwaye uxhulumaniso lombhobho luqiniswe ngokudibeneyo, kwaye i-elastomer gasket esabelayo yoxinzelelo ifakwe kwi-joint. Indlu yokudibanisa ijikeleze ngokupheleleyo i-gasket, iqinisa isitywina kwaye ibambe endaweni, kuba ukudibanisa kudibanisa kunye nokwenza i-interlock ethembekileyo kwi-groove yepayipi. Itekhnoloji yamva nje yokudibanisa ivumela imibhobho ukuya kuthi ga kwi-intshi ezingama-600 (iimilimitha ezingama-600) ububanzi ukuba idityaniswe ngokupheleleyo ngamandongomane kunye neebholiti ezimbini ukuze kuqiniswe amalungu azibambayo. Ngenxa yobudlelwane boyilo phakathi kwemibhobho, i-gaskets, kunye nezindlu, i-mechanical joints yenza itywina eliphindwe kathathu. Olu dlelwane luya komelezwa xa inkqubo icinezelwa. Amalungu aqinileyo kwaye aguquguqukayo afumaneka ngeendlela ezimbini: eziqinileyo kunye neziguquguqukayo. I-Groove mechanical pipe joints idlulise isiqinisekiso sohlobo loluntu kwaye inokutshintsha iindlela zokudibanisa i-welding / flange kwiinkqubo ze-30, kuxhomekeke kwimigangatho yokufakela ebekwe ngumzimba ngamnye wokuqinisekisa. Umzekelo, sebenzisa ukudityaniswa okuqinileyo kwindawo ezinje ngee-manifolds kunye neevalvu, apho kulula ukufikelela kuzo kunye nokutshintsha kuneflange. Ngenxa yobume boyilo lwayo, ukudibanisa okuqinileyo kukwabonelela ngokuqina kwe-axial kunye ne-radial efaniswa neeflange okanye i-welded joints. Ukongeza kwintshukumo yombhobho obangelwa ukwanda kwe-thermal okanye ukunyakaza, amajoyina aguquguqukayo aneenzuzo kwizicelo apho ukunyakaza okuhambelanayo phakathi kombhobho kunye nesakhiwo esixhasayo kulindeleke. Ukwandiswa kunye nokunciphisa kubeka uxinzelelo kwiiflange kunye nemibhobho, ethi ekuhambeni kwexesha inokulimaza i-gasket. Xa oku kwenzeka, kukho umngcipheko wokuvuza kumalungu. I-groove-type flexible coupling inokulungelelanisa ukufuduka kombhobho ngendlela ye-axial movement okanye i-angular deflection. Ngenxa yesi sizathu, zifaneleke kakhulu ukufakela imibhobho emide, ngakumbi phakathi kweebhloko. Ulwandle oluphezulu lunokubangela ukuba iiflange ziyeke ukuhamba kwexesha, okukhokelela kumngcipheko wokuvuza kunye nokwahlulwa kwemibhobho. Ukudibanisa okuqinileyo kunye nokuguquguqukayo kunenzuzo yokunciphisa ingxolo kunye nokunciphisa i-vibration, ngaphandle kwesidingo samacandelo akhethekileyo okunciphisa ingxolo kunye nemivumbo yerabha etshabalalayo okanye izinto ezifanayo. Ukusetyenziswa kweenkqubo zombhobho owenziwe ngoomatshini kunokukhawulezisa nokwenza lula ukufakela nokugcinwa, kunye nokuphucula ukusebenza kakuhle kwenkqubo yemibhobho yenqanawa. Ukufakela ngokulula Xa ufaka okokuqala, imingxuma ye-bolt ye-flange kufuneka ihambelane ngokuchanekileyo, kwaye emva koko iqiniswe ukulungisa ukudibanisa. Izalathisi zomngxuma we-bolt kwi-inlet yezixhobo kunye ne-outlet kufuneka kwakhona zihambelane ngokugqibeleleyo kunye neeflange kwimibhobho ukuba idibaniswe nesixhobo. Ekubeni inani lemingxuma kwi-flange limisela enye yeendawo ezininzi ezizinzileyo, kuphela i-fitting okanye ivalve inokujikelezwa ukuze ifanise imingxuma yebholithi. Ukongezelela, enye isiphelo sombhobho we-flange kufuneka kwakhona ihambelane ne-mating flange yayo, eyongeza ngakumbi ubunzima bokuhlanganisana kunye nomngcipheko wokungahambi kakuhle. Inkqubo yokubhobhoza i-grooved ayinayo le ngxaki, kwaye ukufakela kulungeleka ngakumbi. Imibhobho kunye neendawo zokukhwelana zinokujikeleziswa ngokupheleleyo ngama-360 degrees. Akukho mzekelo womngxuma webholithi wokulungelelanisa, kwaye ukudibanisa kunokubekwa naphi na malunga nendawo edibeneyo. Ukudibanisa kunokujikelezwa kumbhobho ukuze kube lula ukufikelela kwiibholithi kunye nokufikelela lula kwisixhobo. Ukongeza ekupheliseni ukungahambi kakuhle ngexesha lofakelo, umsebenzi wokuqhelaniswa ne-360-degree of coupling kunye neprofayili yayo encinci xa kuthelekiswa ne-flanges yenza ukufakwa kwenkqubo ye-groove ifaneleke kakhulu kwiindawo ezincinci. Ukongeza, i-installer inokubeka zonke iibholiti zendibano kwilungu ngalinye kwindawo efanayo ukuququzelela ukuhlolwa nokugcinwa kwenkqubo. Iiflange ziphantse ziphindwe kabini ububanzi bangaphandle bombhobho apho zidibaniswe khona. Ngokomyinge, amajoyina agudileyo asisiqingatha kuphela salo bukhulu. Ubungakanani benzuzo yoyilo oluncinci lwenza ukuba inkqubo yegroove ilungele imisebenzi ebambekayo, efana nedekhi kunye nokungena eludongeni-inyani eyaqatshelwa kwangoko ngeminyaka yee-1930s, xa ii-Victaulic joints zaqala ukusetyenziswa kwiindawo zeenqanawa zaseBritane. Isantya seNdibano Ngenxa yokuba udibaniso luneebholiti ezimbalwa kwaye alunayo imfuneko yetorque ukuya kuthi ga kwi-12” (300mm), imibhobho egrunjiweyo inokufakwa ngokukhawuleza kakhulu kuneeflange. Ngokungafaniyo ne-flanges emele idityaniswe kwiiphelo zombhobho, iindibano zevalve ye-grooved Akukho welding efunekayo, okunciphisa ngakumbi ixesha lokufakela kunye nokuphelisa umonakalo onokuthi ube ne-thermal kwi-valve, ngelixa unciphisa imingcipheko yokhuseleko ngokuphelisa ukusetyenzwa kwe-thermal. Ukuthelekiswa kwe-DIN 150 umgca we-ballast ofakwe kunye neemveliso ze-Victaulic grooved kunye neendlela zokudibanisa zendabuko Ubonisa ukuba ixesha elipheleleyo lokufakela elifunekayo liye lancitshiswa ngama-66% (iiyure ze-150.47 kunye ne-443.16 iiyure zabantu). Xa kuthelekiswa nama-60 adityanisiweyo aqinileyo, ixesha elifunekayo lokufaka iiflange zemikhono eslayidi ezingama-52 kunye neengqiniba ezidityanisiweyo kunye neetiyi zibonisa Owona mahluko mkhulu wexesha. Ukudibanisa kufuna iibholiti ezimbini kuphela, kwaye ububanzi bombhobho bunokufikelela kuma-intshi angama-24 (600 mm). Ngokwahlukileyo, kuluhlu lobukhulu obukhulu, i-flange idinga ubuncinane iiseti ze-20 zamantongomane kunye neebholiti. Ukongeza, indlela ye-Lan kufuneka isebenzise ii-wrenches ezikhethekileyo zokuqinisa ipateni yeenkwenkwezi ezithatha ixesha lokulinganisa kunye nokuqinisekisa ukuba imilinganiselo yetorque echanekileyo ifikelelwe. Itekhnoloji ye-tube ye-grooved ivumela ukusetyenziswa kwezixhobo eziqhelekileyo zezandla zokudibanisa ukudibanisa, emva kokuba iipads zokukhwelana zezindlu zokudibanisa zidibana nentsimbi yentsimbi. Ukuhlola okubonakalayo okulula kunokuqinisekisa ukudibanisa okuchanekileyo. Ngakolunye uhlangothi, iiflange aziboneleli ngokuqinisekiswa okubonakalayo: indlela yodwa yokuqinisekisa indibano echanekileyo kukugcwalisa kunye noxinzelelo lwenkqubo, ukujonga ukuvuza kunye nokwakha kwakhona njengoko kuyimfuneko Qinisa amajoyina. Inqaku elifanayo lenkqubo yokugcinwa kwemibhobho yegrooved kukuba ikhawulezisa ufakelo-iibholiti ezimbalwa kwaye akukho mfuneko yetorque-kwaye yenza ukugcinwa kwenkqubo okanye ukuguqulwa kube ngumsebenzi okhawulezayo nolula. Ngokomzekelo, ukufikelela kwiimpompo okanye kwii-valve, khulula iibholiti ezimbini zokudibanisa, kwaye ususe indlu kunye ne-gasket kwi-joint. Kwinkqubo yeflange, iibholiti ezininzi kufuneka zisuswe. Xa uphinda udibanisa i-flange, ukufakwa kokuqala kwexesha elifanayo kuyafuneka. Ulandelelwano lokuqinisa ibholithi. Ngenxa yokuba akufuneki ukuba ziphinde ziqiniswe, ukudityaniswa kuphelisa ukugcinwa kwemihla ngemihla ehambelana neeflange. Ngokungafani nama-flanges asebenzisa uxinzelelo oluguquguqukayo kwi-washers, i-nuts, kunye ne-bolts, i-couplings iguqula i-washers ukusuka ekunyanzelweni okuchanekileyo kwangaphandle kombhobho wombhobho. Ukongezelela, ngenxa yokuba i-gasket yokudibanisa ayichaphazeli amandla aphezulu, ayifuni ukutshintshwa rhoqo, ngelixa i-gasket ye-flange idinga ukutshintshwa ngexesha lokuchithwa kwenkqubo kunye nokugcinwa. Ukuze kuncitshiswe ingxolo yenkqubo kunye nokungcangcazela, inkqubo yeflange Ifuna imibhobho yerabha okanye imibhobho eguquguqukayo ephothiweyo. Ezi zixhobo zinokungaphumeleli ngenxa yokwelula okugqithisileyo, kwaye phantsi kokuguga kunye nokukrazula okuqhelekileyo, kufuneka zitshintshwe rhoqo emva kweminyaka eyi-10 ngokomndilili, okukhokelela kwiindleko kunye nexesha lokunciphisa inkqubo. Nangona kunjalo, i-mechanical grooved pipes I-Joints inokwandisa ubomi benkqubo. Ukukwazi kwabo ukulungelelanisa ukunyakaza kwenkqubo kunciphisa umngcipheko wokungaphumeleli ngokubambisana ngaphandle kwesidingo seemveliso ezikhethekileyo ezifuna ukugcinwa rhoqo okanye ukutshintshwa. I-elastic spring washers ezibandakanyiweyo kwi-flexible and rigid couplings yomelele kakhulu kwaye inokumelana noxinzelelo olukhulu olusebenzayo kunye nomthwalo we-cyclic. Inkqubo inokunyanzeliswa ngokuphindaphindiweyo kwaye igxininiswe ngaphandle kokukhathala kwe-elastomer gasket. Indibano yevalve yokunciphisa ubunzima idla ngokuqulunqwa ngamacandelo eflange. Nangona kunjalo, le ndlela yokudibanisa iyakongeza ngokungeyomfuneko kwinkqubo yokubhobhoza Ubunzima. I-intshi ezi-6 (i-150 mm) ivalve ye-flange yevalve ibandakanya ivalve yebhabhathane yelug Yakhiwe, idityaniswe kwiflange yentamo edityanisiweyo, kunye neebholiti ezisibhozo kunye namandongomane kwicala ngalinye levalve, inobunzima obumalunga neepounds ezingama-85. I-intshi ezi-6 (i-150 mm) i-valve yevalve isebenzisa ivalve yebhabhathane egrunjiweyo, i-grooved end pipe, kunye nezidibanisi ezibini eziqinileyo ukudibanisa indibano. Inobunzima obumalunga neepounds ezingama-35, obuyi-58% ubunzima obungaphantsi kunendibano yeflange. Ke ngoko, indibano yevalve ye-grooved iyindawo efanelekileyo yoshishino lokwakha iinqanawa. Ukuthelekiswa kwemibhobho ye-DIN 150 ye-ballast efakwe ngasentla ibonisa ukuba xa iimveliso ze-Victaulic grooved zisetyenziselwa endaweni yendlela yokudibanisa yendabuko, ubunzima buncitshiswa nge-30% (2,164 lbs vs. 3,115 lbs). Xa kuthelekiswa ne-60 yokudibanisa okuqinileyo, i-52 i-sleeve flanges, iiseti ze-bolt kunye ne-washers kubangela ukwanda kobunzima be-welding / flange system. Ukusetyenziswa kwamalungu emibhobho e-grooved endaweni ye-flanges kunokunciphisa ubunzima kwaye ifanelekile kwimibhobho yobukhulu obuhlukeneyo. Ubungakanani bokunciphisa buxhomekeke kububanzi bombhobho kunye nohlobo lwamalungu asetyenziswayo. Kuvavanyo olusebenzisa i-Victaulic 77 coupling (eyona nto inzima kakhulu yokudibanisa kwi-series) ukudibanisa umbhobho, ubunzima obupheleleyo bofakelo becandelo le-grooved laliphantsi kakhulu kune-sleeve flanges ezimbini ezilula ze-PN10. Ukulahlekelwa kwesisindo kubhalwe ngolu hlobo lulandelayo: 4 "(100mm) - 67%; 12” (300mm) – 54%; 20 intshi (500 mm) - 60.5%. Ukusetyenziswa kohlobo olulula oluguquguqukayo lwe-75 okanye uhlobo oluqinileyo lwe-07 yokudibanisa kunye / okanye iintlobo ezinzima ze-flange zinokufikelela ngokulula kwi-70% yokunciphisa ubunzima. Ngokomzekelo, i-24-intshi (600 mm) iflange iseti esetyenziswe kwinkqubo ye-TG2 inobunzima be-507 pounds, kodwa amacandelo afanayo asebenzisa i-Victaulic fittings inobunzima be-88 kuphela. Iinqanawa ezisetyenziselwa ngokukhethekileyo i-grooved couplings endaweni ye-flanges kwiinkqubo ezikhethiweyo ziye zabhala ukuba iinqanawa zenkxaso ye-offshore ziye zanciphisa ubunzima ngeetoni ezili-12 kunye neenqanawa zokuhamba ngeenqanawa ziye zanciphisa ubunzima ngeetoni ezingama-44. Iinzuzo zoqoqosho eziziswa bubugcisa bomkhombe kubanikazi beenqanawa zicacile: ubunzima obulula buthetha imithwalo eninzi okanye abakhweli kunye nokusetyenziswa kancinci kwamafutha. Yenza kwakhona ukuphatha inkqubo yemibhobho yenqanawa lula. Umkhwa woPhuhliso Ngenxa yesantya sofakelo olukhawulezayo, ukugcinwa okuqinileyo kunye nobunzima bokukhanya, iinkqubo zemibhobho yomkhombe zinokubonelela ngeenzuzo ezibaluleke ngakumbi kuneemveliso ezifanayo zeflange. Ezi mpawu, zidityaniswe neenzuzo ezongezelelweyo ezifana nokuthembeka, ukukhululeka kolungelelwaniso kunye neengozi ezisezantsi zokhuseleko, ziye zabangela ukuba abanini beenqanawa, iinjineli kunye neendawo zeenqanawa zikhethe iinkqubo zoomatshini ezigudileyo endaweni yeeflange.
