UDidier Vassal, uSekela Mongameli we-Victaulic OEM kunye neeNkonzo zaseLwandle, uthelekisa iindlela zokudityaniswa kwemibhobho ene-flanged kunye ne-grooved kwaye wachaza iingenelo zokudityaniswa kombhobho we-grooved ukubonelela ngeeflanges. Iinkqubo zombhobho ezisebenzayo ziyimfuneko kwiinkonzo ezininzi ezifunekayo kwiinqanawa, kubandakanywa iinkqubo ezincedisayo ezifana ne-bilge kunye ne-ballast systems, ukupholisa ulwandle kunye namanzi amatsha, ioli yokuthambisa, ukukhuselwa komlilo kunye nokucoca i-deck. Kwezi nkqubo zivunyelwe libakala lokubhobhoza, enye indlela esebenzayo ekusetyenzisweni koqhagamshelo lomatshini oludityanisiweyo kukusebenzisa ii-slotted mechanical joints, ezibonelela ngothotho lweenzuzo zobugcisa, ezoqoqosho kunye nezokusebenza. Oku kubandakanya ukusebenza okuphuculweyo; ngokukhawuleza kwaye kulula ukufakela kunye nokugcinwa, kunye nokunciphisa ubunzima bomoya. 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, ngenxa yokuguquguquka koxinzelelo, uxinzelelo lwenkqubo yokusebenza, ukungcangcazela, kunye nokwandiswa kwe-thermal kunye nokucutha, iibholiti kunye namantongomane anokolula kwaye aphulukane nokuqina kwawo kwasekuqaleni. Xa ezi bholiti zithomalalisa i-torque, i-gasket iya kuphulukana nesitywina sayo soxinzelelo, nto leyo eya kubangela ukuvuza kwamanqanaba ahlukeneyo. Ngokuxhomekeke kwindawo kunye nomsebenzi wenkqubo yemibhobho, ukuvuza kunokubangela iindleko eziphezulu kunye neengozi, ezikhokelela ekugcinweni / ukulungiswa kwexesha lokunciphisa kunye nomngcipheko. Emva kokususa umdibaniso, i-gasket iya kufuna ukutshintshwa ngenxa yokuba i-gasket iya kubambelela kwindawo ye-flange ixesha elithile. Xa udibanisa i-joint, i-gaskets kufuneka ikhutshwe kwiindawo ezimbini ze-flange, kwaye le mimandla kufuneka ihlambuluke ngaphambi kokuba ithathe indawo ye-gaskets, eyandisa ixesha lokulondoloza. Ngenxa yamandla ebholithi kunye nokwandiswa kunye nokuncipha kwenkqubo, i-gasket ye-flange nayo iya kuvelisa i-compression "deformation" ngokuhamba kwexesha, enye into ebangela ukuvuza. Uyilo lwe-grooved mechanical pipe joint yoyisa ezi ngxaki zokusebenza. Okokuqala, i-groove yenziwe ekupheleni kombhobho, kwaye uxhulumaniso lombhobho luqiniswa ngokudibanisa okubandakanya i-elastomer gasket, i-elastomer ephendula uxinzelelo. Indlu yokudibanisa ijikeleze ngokupheleleyo i-gasket, iqinisa isitywina kwaye iyilungise endaweni, kuba ukudibanisa kubandakanyeka kwaye kwenza i-interlock ethembekileyo kwi-groove yepayipi. Itekhnoloji yoqhagamshelo yamva nje yenza ukuba imibhobho ukuya kuthi ga kwi-intshi ezingama-24 (600 mm) ububanzi ukuba idityaniswe ngokupheleleyo ngamantongomane amabini kuphela kunye neebholiti ukuze kukhuseleke amajoyinti okuzibamba. Ngenxa yobudlelwane boyilo phakathi kombhobho, i-gasket, kunye nezindlu, i-joint joint mechanical yenza itywina eliphindwe kathathu, eliphuculweyo xa inkqubo icinezelwa. I-Rigid kunye ne-Flexible Couplings I-Slotted mechanical pipe i-couplings ifumaneka kwiifom eziqinileyo kunye neziguquguqukayo, zombini ezivunyiweyo luluntu lokuhlela, kwaye zingasetyenziselwa indawo ye-welding / flange indlela kwiinkqubo ze-30, kodwa kufuneka zihambelane nemigangatho yoFakelo ngalunye. esekwe liqumrhu lezatifiketi. Ukudityaniswa okuqinileyo kusetyenziswa, umzekelo, malunga neendawo ezinjengee-manifolds kunye neevalvu, kwaye kulula ukufikelela kuzo kunye nokutshintsha kuneflange. Ngokobume boyilo lwayo, ukudityaniswa okuqinileyo kukwabonelela ngokuqina kwe-axial kunye ne-radial enokuthelekiswa neeflange okanye i-welded joints. Ukudibanisa okuguquguqukayo kunenzuzo kwizicelo. Ukongeza kwintshukumo yombhobho ngenxa yokwandiswa kwe-thermal okanye i-vibration, ukunyakaza okuhambelanayo phakathi kombhobho kunye nesakhiwo esixhasayo kulindeleke. Ukwandiswa kunye nokunciphisa kubeka uxinzelelo kwiiflange kunye nemibhobho, enokonakalisa i-gasket ngokuhamba kwexesha. Xa oku kusenzeka, amalungu asengozini yokuvuza. I-grooved flexible coupling inokwamkela ukufuduka kombhobho ngendlela ye-axial movement okanye i-angular deflection. Ngoko ke, zilungele ukufakela imibhobho emide, ngakumbi phakathi kweebhloko ezinkulu apho i-atmosfera yolwandle inokubangela ukuba i-flanges ikhululeke ngokuhamba kwexesha, okukhokelela ekuvuzeni kunye nomngcipheko wokwahlulwa kwemibhobho. Ukudityaniswa okuqinileyo kunye nokudibanisa okuguquguqukayo kunenzuzo yokunciphisa ingxolo kunye nokungcangcazela, ngaloo ndlela kuphelisa isidingo samacandelo akhethekileyo okunciphisa ingxolo kunye nemivumbo yerabha etshabalalayo okanye izinto ezifanayo. Ukusetyenziswa kweenkqubo zemibhobho efakwe ngoomatshini kunokukhawulezisa kwaye kube lula ukufakela nokugcinwa, kunye nokwandisa ukusebenza kakuhle kwenkqubo yemibhobho ekwibhodi. 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. Kwimeko enye yeendawo ezininzi ezisisigxina ezinqunywe kuphela ngenani lemingxuma kwi-flange, i-fitting okanye i-valve kuphela inokujikelezwa ukuze ihambelane nemingxuma ye-bolt. 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 inokufakwa ngokulula ngakumbi, kwaye umbhobho kunye namacandelo okukhwelana angajikelezwa ngokupheleleyo kwii-360 degrees. Akukho mfuneko yokucwangcisa ipateni yomngxuma we-bolt, kwaye ukudibanisa kunokujoliswa kuyo nayiphi na indawo ejikeleze umdibaniso. Ukudibanisa kunokujikeleza kumbhobho ukufikelela ngokulula kwiibholithi kunye nokwenza lula ukufikelela kwisixhobo. Ukongeza ekupheliseni ukungahambi kakuhle ngexesha lokufakela, umsebenzi wokuqhelanisa i-360-degree of coupling kunye neprofayili encinci xa kuthelekiswa ne-flange yenza ukufakwa kwenkqubo ye-groove ibe yinto efanelekileyo yokukhetha iindawo ezinqabileyo. Ukongeza, i-installer inokulungelelanisa zonke iibholiti zendibano kwikhonkco ngalinye kwindawo efanayo ukwenza lula ukuhlolwa kwenkqubo kunye nokugcinwa. I-flange imalunga nokuphindwe kabini ububanzi bangaphandle bombhobho odibeneyo. Ngokomyinge, ukudityaniswa kwe-grooved kuphela sisiqingatha sobu bukhulu. Inzuzo yobungakanani boyilo oluncinci lwenza kube lukhetho olufanelekileyo kwiinkqubo zomkhombe, ezilungele ukusebenza kunye nesithuba esincinci, njengokungena kweedekhi kunye neendonga. Le nyaniso inokulandwa emva phaya kwiminyaka yoo-1930s, xa iVictaulic couplings yaqala ukusetyenziswa kwiindawo zeenqanawa zaseBritane. Isantya seNdibano Ngenxa yokuba ukudibanisa kuneebholiti ezimbalwa kwaye imfuno ye-torque ayidluli i-intshi ezili-12 (300 mm), ukufakwa kwemibhobho ye-grooved ngokukhawuleza kunokufakwa kwe-flange. Ngokungafaniyo neeflange ezimele zidityaniswe kwiziphelo zemibhobho, amacandelo evalve egrunjiweyo ayifuni ukuwelda, nto leyo enciphisa ngakumbi ixesha lofakelo, iphelisa umonakalo onokubakho wobushushu kwivalve, kwaye inciphisa imingcipheko yokhuseleko ngokuphelisa imisebenzi yobushushu obuphezulu. Ukuthelekiswa kwe-DIN 150 imigca ye-ballast efakwe usebenzisa iimveliso ze-Victaulic grooved kunye neendlela zokudibanisa zendabuko zibonisa ukuba ixesha elipheleleyo lokufakela elifunekayo liye lancitshiswa ngama-66% (iiyure ze-150.47 kunye ne-443.16 iiyure zomntu). Xa kuthelekiswa nokufakwa kwe-60 yokudibanisa okuqinileyo, ixesha elifunekayo ukufaka i-52 slide-in flanges, i-elbows ye-welding kunye ne-tee inomahluko omkhulu. Ukudibanisa kufuna iibholiti ezimbini kuphela ukufikelela kubungakanani bombhobho wama-intshi angama-24 (600 mm). Ukuthelekisa, kuluhlu lobukhulu obukhulu, i-flange idinga ubuncinane iiseti ezingama-20 zamantongomane kunye neebholiti. Ukongezelela, i-flange idinga ukusetyenziswa kweenkwenkwezi zeenkwenkwezi ezichitha ixesha ukuba ziqiniswe nge-wrench ekhethekileyo yokulinganisa kunye nokuqinisekisa ukuba i-torque echanekileyo ifikeleleke. Itekhnoloji ye-tube ye-grooved ivumela ukusetyenziswa kwezixhobo zezandla eziqhelekileyo ukudibanisa ukudibanisa, kwaye emva kokuba i-pad bolt bolt yendlu yokudibanisa ichukumisa isinyithi kwisinyithi, idibeneyo inokufakwa ngokufanelekileyo. Ukuhlola okubonakalayo okulula kunokuqinisekisa ukudibanisa okuchanekileyo. Ngakolunye uhlangothi, iiflange aziboneleli ngokuqinisekiswa okubonakalayo: indlela yodwa yokuqinisekisa ukudibanisa okufanelekileyo kukugcwalisa kunye noxinzelelo lwenkqubo, ukujonga ukuvuza kunye nokuphinda uqinise amajoyina njengoko kufuneka. Ukugcinwa kwenkqubo yemibhobho egrunjiweyo ineempawu ezifanayo zofakelo olukhawulezileyo-iibholiti ezimbalwa kwaye akukho mfuneko yetorque-kwaye yenza ukugcinwa kwenkqubo okanye ukutshintsha umsebenzi okhawulezayo nolula. Ukufikelela kwimpompo okanye i-valve, umzekelo, khulula iibholiti ezimbini zokudibanisa kwaye ususe indlu kunye ne-gasket kwi-joint. Kwinkqubo yeflange, iibholiti ezininzi kufuneka zisuswe. Xa uphinda ufaka i-flange, inkqubo yokuqinisa i-bolt yexesha elifanayo kufuneka yenziwe ngexesha lofakelo lokuqala. Ngenxa yokuba akukho mfuneko yokuqinisa kwakhona, ukudibanisa kusindisa umsebenzi omningi wokugcinwa kwesiqhelo onxulumene neeflange. Ngokungafani neeflange apho uxinzelelo oluguquguqukayo lusetyenziswa kwiiwashers, amantongomane kunye neebholiti, ukudibanisa kubamba ama-washers ukusuka ngaphandle kombhobho odibeneyo kunye nemikhosi yoxinzelelo oluchanekileyo. Ukongezelela, ekubeni i-gasket yokudibanisa ayithwali uxinzelelo oluphezulu, akuyimfuneko ukuyibuyisela ngokuhambelana neshedyuli yokugcinwa rhoqo, kwaye i-gasket ye-flange idinga ukutshintshwa xa inkqubo ichithwa ukuze igcinwe. Ukunciphisa ingxolo kunye nokungcangcazela kwenkqubo, inkqubo ye-flange kufuneka isebenzise i-rubber bellows okanye i-hoses ephothiweyo. Ezi zinto zinokungaphumeleli ngenxa yokwelula, kwaye phantsi kokuguga okuqhelekileyo, kufuneka zitshintshwe ngokomyinge rhoqo emva kweminyaka eyi-10, nto leyo enokukhokelela kwiindleko kunye nexesha lokunciphisa inkqubo. Nangona kunjalo, iintambo zombhobho kunye ne-grooves mechanical zingandisa ubomi benkqubo. Banamandla okulungelelanisa ukunyakaza kwenkqubo kunye nokunciphisa umngcipheko wokungaphumeleli ngokubambisana ngaphandle kwesidingo seemveliso ezikhethekileyo ezifuna ukugcinwa rhoqo okanye ukutshintshwa. Izixhobo zokuhlamba i-spring elastic eziqulethwe kwi-flexible and rigid couplings zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona. Inkqubo inokunyanzeliswa kwaye igxininiswe ngokuphindaphindiweyo ngaphandle kokukhathala kwe-elastomer gasket. Amacandelo evalve ekhaphukhaphu ahlala equlunqwe ngamacandelo e-flange. Nangona kunjalo, le ndlela yokudibanisa yongeza ubunzima obungeyomfuneko kwinkqubo yokubhobhoza. Ivalve yeflange eyi-6-intshi (150 mm) inevalve yelug butterfly. Ivalve yebhabhathane idityaniswe neflange yentamo edityanisiweyo, kwaye iibholiti ezisibhozo kunye namantongomane ziqhagamshelwe kwicala ngalinye levalve, ezinobunzima obumalunga neekhilogram ezingama-85. I-valve ye-intshi ezi-6 (i-150 mm) isebenzisa ivalve yebhabhathane enencam yegrooved, umbhobho onomphetho ogobileyo, kunye nezidibanisi ezibini eziqinileyo ukudibanisa la malungu. Ubunzima bumalunga ne-35 pounds, eyi-58% elula kunendibano ye-flanged. . Ke ngoko, indibano yevalve ye-grooved lolona khetho lufanelekileyo kwishishini lokwakha iinqanawa. Xa usebenzisa iimveliso ze-Victaulic grooved endaweni yendlela yokudibanisa yendabuko, uthelekiso olungentla lwe-DIN ye-150 ye-ballast efakiweyo ibonisa ukunciphisa ubunzima be-30% (2,164 pounds vs. 3,115 pounds). I-52 i-sliding flanges, iiseti ze-bolt kunye ne-washers, ngelixa i-60 i-couplings eqinile i-akhawunti yobunzima obuninzi kwi-welding / flange system. Kwimibhobho yobukhulu obahlukeneyo, ubunzima buya kuncitshiswa ngokusebenzisa i-grooved pipe joints endaweni yeeflanges. Ubungakanani bokunciphisa buxhomekeke kububanzi bombhobho kunye nohlobo lwamalungu asetyenziswayo. Kuvavanyo olusebenzisa i-Victaulic Style 77 coupling (i-coupling enzima kakhulu kuluhlu) ukudibanisa umbhobho, ukufakwa okupheleleyo kwendibano ye-grooved xa kuthelekiswa nobunzima obubini be-PN10 slide-in flanges Ubunzima buphantsi kakhulu. Ukulahlekelwa kwesisindo kubhalwa ngolu hlobo lulandelayo: 4 intshi (100 mm) -67%; 12 intshi (300 mm)-54%; 20 intshi (500 mm) -60.5%. Ukusetyenziswa kohlobo olulula oluguquguqukayo lwe-75 okanye uhlobo oluqinileyo lwe-07 yokudibanisa kunye / okanye i-flanges enzima inokufikelela ngokulula kwi-70% yokunciphisa ubunzima. Ngokomzekelo, i-24-intshi (i-600 mm) ikiti ye-flange esetyenziswe kwinkqubo ye-TG2 inobunzima be-507 pounds, ngelixa amacandelo afanayo asebenzisa i-Victaulic connectors inobunzima be-88 kuphela. Kwinkqubo ekhethiweyo, indawo yeenqanawa, esebenzisa imidibaniso enegrooved ngokukhetha iiflange, yanciphisa ubunzima kwiinqanawa zenkxaso ye-offshore ngeetoni ezili-12 nakwiinqanawa zokuhamba ngeetoni ezingama-44. Iingenelo zezoqoqosho zokubeka ubugcisa kubaphathi beenqanawa zicacile: ukunciphisa ubunzima kuthetha ukwandisa inani lempahla okanye abakhweli kunye nokunciphisa ukusetyenziswa kwepetroli. Oku kwenza ukuba ukuphathwa kwenkqubo yemibhobho yenqanawa kube lula. Indlela yokuphuhla Iinkqubo zemibhobho e-Grooved zineengenelo ezinkulu kwiinkqubo zemibhobho ene-flanged ngenxa yesantya sofakelo lwazo, ukugcinwa kunye nokunciphisa ubunzima. Ezi mpawu, zidityaniswe nezinye iingenelo ezifana nokuthembeka, ulungelelwaniso olulula kunye neengozi ezisezantsi zokhuseleko, ziye zakhuthaza abanini beenqanawa, iinjineli kunye neendawo zeenqanawa ukuba bakhethe iinkqubo zoomatshini ezityibilikileyo endaweni yeeflange. Indlela ekhulayo yokusetyenziswa kweteknoloji ye-groove ixhaswa ngababoneleli bezixhobo (ezifana nokutshintsha ubushushu, i-box coolers kunye ne-coolers) kunye ne-valve kunye nabavelisi be-compressor, abaninzi babo ngoku banikezela ngeemveliso zabo Ukubonelela nge-grooved end connection.
