UDidier Vassal, uSekela Mongameli we-OEM kunye neeNkonzo zaseLwandle eVictaulic, uthelekisa iindlela zokuxhunyelelwa kombhobho we-flanged kunye ne-grooved kwaye uchaza iingenelo zokufakelwa kwemibhobho egrunjiweyo ngaphezu kwe-flanges. Iinkqubo ze-bilge kunye ne-ballast, ukupholisa kwamanzi olwandle kunye namanzi ahlambulukileyo, i-oyile yokuthambisa, ukukhuselwa komlilo kunye nokucoca i-deck.Kule nkqubo, apho ibakala lombhobho livumela, enye indlela esebenzayo kwi-welding / flanging kukusetyenziswa kwee-slotted mechanical joints ezinikezela uluhlu lwezobugcisa, iinzuzo zoqoqosho kunye nokusebenza.Oku kubandakanya ukwenziwa komsebenzi okwandisiweyo; ngokukhawuleza, ukufakela okulula kunye nokugcinwa kunye nokunciphisa ubunzima bebhodi.Imiba yokuSebenza kwi-flanged fittings, iiflange ezimbini zokukhwelana zibotshwe kunye kwaye zicinezele i-gaskets ukuze zenze i-seal.Ngenxa yokuba iibholiti kunye namantongomane e-flanged joints afunxa kwaye ahlawule imikhosi yenkqubo, inokolula kwaye ilahlekelwa yi-tightness yayo yangaphambili ngokuhamba kwexesha ngenxa yokuguquguquka koxinzelelo, uxinzelelo lwenkqubo yokusebenza, ukungcangcazela, kunye nokwandiswa kwe-thermal kunye nokunciphisa. indawo kunye nomsebenzi wenkqubo yokubhobhoza, ukuvuza kunokuba yindleko kwaye kuyingozi, okukhokelela ekugcinweni / ukulungiswa kwexesha lokunciphisa kunye nomngcipheko.I-gasket iya kufuna ukutshintshwa xa i-joint ichithwa ngenxa yokuba ngokuhamba kwexesha i-gasket iya kudibanisa kwi-flange face.Xa ichithwa i-fitting, i-gaskets kufuneka ikhutshiwe ebusweni bobabini be-flange, kwaye le miphezulu kufuneka icocwe ngaphambi kokutshintshwa kwee-gaskets, iphinde ikhulise ukugcinwa kwexesha lokugcinwa. , ongomnye unobangela wokuvuza.Uyilo lwezixhobo zokufakelwa koomatshini ezigudisiweyo ziyayoyisa le miba yokusebenza.I-groove yenziwa kuqala kwisiphelo sombhobho, kwaye uqhagamshelo lombhobho lukhuselwe ngesidibanisi esifaka i-elastomer gasket ekwazi ukumelana noxinzelelo. izindlu zijikeleze ngokupheleleyo i-gasket, iqinisa itywina kwaye ibambe endaweni xa ukudibanisa kubandakanywa kunye nokudala ukudibanisa okulungileyo kwi-tube groove.Ubuchwephesha bokujoyina bamva nje buvumela imibhobho ukuya kwi-24 "(600mm) ububanzi ukuba idityaniswe ngokupheleleyo kunye neebini nje ezimbini. amantongomane kunye neebholiti zokukhusela i-self-restraining joints.Ilungu lomatshini lidala itywina kathathu ngenxa yobudlelwane boyilo phakathi kombhobho, i-gasket, kunye nezindlu, eziphuculweyo xa inkqubo ixinzezelekile. i-slotted mechanical couplings yi-Class Society Type eVunyiweyo kwaye ingasetyenziselwa endaweni yendlela ye-weld / flange kwiinkqubo ze-30 ngokuxhomekeke kwimigangatho yokufakela esekwe yi-arhente nganye eqinisekisayo.Ngokomzekelo, sebenzisa ukudibanisa okuqinileyo kwiindawo ezifana ne-manifolds kunye ne-valve, ekulula ukuyenza. ukufikelela kunye nokutshintsha kune-flanges.Ngokuxhomekeke kubume boyilo lwazo, ukudityaniswa okuqinileyo kukwabonelela ngokuqina okungafaniyo kwe-axial kunye ne-radial kwi-flanged okanye i-welded joints. phakathi kombhobho kunye nesakhiwo senkxaso kulindeleke.Ukwandiswa kunye nokunciphisa kunokubeka uxinzelelo kwiiflanges kunye nemibhobho, ezonakalisa i-gaskets ngokuhamba kwexesha.Xa oku kwenzeka, i-joint isengozini yokuvuza.Ii-slotted flexible couplings ziyakwazi ukufumana ukufuduka kombhobho ngendlela ye-axial movement. okanye ukuphambuka kwe-angular.Ngenxa yesi sizathu, zilungele ukufakela imibhobho emide, ngakumbi phakathi kweebhloko elwandle oluvulekileyo apho iiflanges zinokukhululeka ngokuhamba kwexesha, okukhokelela kumngcipheko wokuvuza kunye nokwahlula kombhobho.Ukudibanisa okuqinileyo kunye nokuguquguqukayo kukwabonelela ngoncedo lwengxolo. kunye nokudambisa ukungcangcazela, ukuphelisa imfuneko yamacandelo akhethekileyo okunciphisa ingxolo kunye nemivumbo yerabha etshabalalayo okanye efanayo.Ukusetyenziswa kweenkqubo zemibhobho eyenziwe ngoomatshini kunokukhawulezisa nokwenza lula ukufakela nokugcinwa, kunye nokwandisa ukusebenza kweenkqubo zemibhobho ebhodini.Ukulula ukufakela ekuqaleni ukufakela, imingxuma yebholi yeflange kufuneka ilungelelaniswe ngokuchanekileyo kwaye emva koko iqiniswe ukukhusela i-joint.Izalathisi zomngxuma webholi kwisixhobo sokungena kunye nokuphuma kufuneka zilungelelaniswe ngokugqibeleleyo kunye neeflange kwimibhobho edityaniswe nesixhobo. inani lemingxuma kwi-flange imisela kuphela enye yeendawo ezininzi zokulungisa, kuphela i-fitting okanye ivalve inokujikelezwa ukuze ihambelane nemingxuma yebholt.Ukongezelela, esinye isiphelo sombhobho onombhobho kufuneka silungelelaniswe ne-flange yayo yokukhwela, eyongeza ngakumbi. ubunzima bokudibanisa kunye nobungozi bokungahambi kakuhle.Iinkqubo zemibhobho edibeneyo ayinayo le ngxaki, kwaye ivumela ukufakwa lula, kunye nokujikeleza kwe-360-degree ye-piping kunye ne-mating components.Ngaphandle kwepatheni yomngxuma webholi umgca, ukudibanisa kunokubekwa. naphi na malunga ne-joint.I-Couplings inokujikelezwa malunga nombhobho ukuququzelela ukubhobhoza kunye nokwenza lula ukufikelela kwisixhobo.Ukongezelela ekupheliseni ukungahambi kakuhle ngexesha lofakelo, ukuxhamla kwe-360-degree orientation capability, kunye neprofayili yayo encinci xa kuthelekiswa ne-flanges, yenza ukufakwa kwenkqubo ye-grooved. ilungele izithuba ezixineneyo.Ukongezelela, abafakeli bangafumana zonke iibholithi zendibano kwindibaniselwano nganye kwindawo enye ukuze kuhlolwe inkqubo elula kunye nokugcinwa kwayo.IiFlanges zimalunga nedayamitha ephindwe kabini yangaphandle yemibhobho eqhagamshelana kuyo.Ngomndilili, uqhagamshelo olutyhidiweyo sisiqingatha sesi. ubukhulu.Ubukhulu benzuzo yoyilo oluncinci lwenza ukuba inkqubo yegroove ilungele imisebenzi apho indawo incinyiweyo, efana nedesika kunye nokungena eludongeni-inyani leyo yaqatshelwa emva phayaa ngeminyaka yee-1930s xa iVictaulic couplings yayisetyenziswa okokuqala kwiindawo zeenqanawa zaseBritane.Assembly Speed ​​​Umbhobho ogrunjiweyo unokufakwa ngokukhawuleza kakhulu kune-flanged kuba ukudibanisa kuneebholithi ezimbalwa kwaye iimfuno ze-torque azidluli kwi-12" (300mm). Ngokungafaniyo neeflange ekufuneka zidityaniswe kwiziphelo zombhobho, imibhobho egobileyo Indibano yevalve ayifuni i-welding, ephinda icuthe ixesha lofakelo kwaye isuse umonakalo onokuthi ubekho we-thermal kwivalve, ngelixa ikwanciphisa imingcipheko yokhuseleko ngokuphelisa umsebenzi oshushu. I-DIN 150 ye-ballast efakwe kunye neemveliso ze-Victaulic grooved Ukuthelekiswa kocingo kunye neendlela zokudibanisa zendabuko zibonise ukuncipha kwe-66% kwixesha lofakelo lilonke elifunekayo (iiyure ze-150.47 kunye ne-443.16 iiyure zomntu). Ukufakwa kwe-52 slip flanges kunye neengqinisiso ezidityanisiweyo kunye nee tee xa kuthelekiswa ne-60 couplings eqinile Ixesha elifunekayo libonisa umahluko omkhulu kwixesha. Ukudibanisa kufuna kuphela iibholiti ezimbini ukuya kwi-24 "(600 mm) ubukhulu bombhobho. Ngokwahlukileyo, iiflange zifuna ubuncinane iiseti ezingama-20 zamantongomane kunye neeBolts. Ukongezelela, iiflange zifuna ixesha lokuqiniswa kweenkwenkwezi kunye ne-wrench ekhethekileyo yokulinganisa kunye nokuqinisekisa okuchanekileyo. Ukucaciswa kwe-torque kufezekisiwe. Iiflange, ngakolunye uhlangothi, azinikezeli ukuqinisekiswa okubonakalayo: indlela yodwa yokuqinisekisa ukuba indibano echanekileyo yinkqubo yokuzaliswa kunye noxinzelelo, khangela Ukuvuza kunye nokuqinisa amajoyina njengoko kufunekayo Iipropati ezifanayo zeenkqubo zombhobho we-grooved ezikhawuleza ukufakwa-iibholiti ezimbalwa kunye no Iimfuno ze-torque-kwakhona yenza ukugcinwa kwenkqubo okanye ukubuyisela kwakhona umsebenzi okhawulezayo kunye nokulula, umzekelo, Ukufumana ukufikelela kwimpompo okanye i-valve, khulula iibholiti ezimbini zokudibanisa kwaye ususe indlu kunye ne-gasket kwi-joint. Kwi-flanged system, iibholiti ezininzi kufuneka zisuswe. Xa uphinda udibanisa i-flange, iyafuneka kwakhona ekufakeni kokuqala Inkqubo efanayo yokuqinisa i-bolt yexesha elifanayo yenziwa kwi-Shaft coupling ibamba i-gasket ngokunyanzeliswa okuchanekileyo ukusuka ngaphandle kwe-fitting. Ukongezelela, ekubeni i-gasket yokudibanisa ayikho phantsi kwamandla aphezulu oxinzelelo, ukugcinwa rhoqo akufunwa, ngelixa i-gasket ye-flange idinga ukutshintshwa xa inkqubo ichithwa ukuze igcinwe. Ukunciphisa ingxolo yenkqubo kunye nokungcangcazela, iisistim ezine-flanged zifuna i-rubber bellows okanye i-hose ephothiweyo. La malungu anokusilela ngenxa yokolulwa kwaye, phantsi kokuguga okuqhelekileyo kunye nokukrazuka, afuna ukutshintshwa ngokomyinge rhoqo emva kweminyaka eli-10, okukhokelela kwiindleko kunye nexesha lokunciphisa inkqubo. Nangona kunjalo, i-mechanical grooved joint joints inokwandisa ubomi benkqubo. Ukukwazi kwabo ukulungiselela ukungcangcazela kwenkqubo kunciphisa umngcipheko wokungaphumeleli ngokubambisana ngaphandle kwesidingo seemveliso ezikhethekileyo ezifuna ukulungiswa rhoqo okanye ukutshintshwa.
