Iiflange zizifakelo zombhobho ezihlala zisetyenziselwa ukudibanisa imibhobho kunye nemibhobho okanye ukudibanisa izixhobo ezimbini kwinkqubo yepayipi.Kukho iintlobo ezininziiiflange,njengeiiflange ezinemisonto, ukuwelda iiflange zentamo, ipleyiti welding flanges, njl. (ezibizwa ngokuba yi-flanges).Nangona kunjalo, kubomi bokwenyani, unokuqaphela ukuba kukho enye imveliso ye-flange ebizwa ngokuba yi-blind flange.Uthini umahluko phakathi kweflange eqhelekileyo kunye neflange eyimfama?Indlela yokufaka kunye nokusebenzisa i-flange eyimfama?
1. Umahluko phakathi kweflange kunye neflange eyimfama
(1) Kukho imingxuma kwiflange.Ngethuba lokuxhamla, iiflange ezimbini kufuneka ziboshwe ngeebholiti.I-flange ivalwe nge-gaskets ukuze idlale indima yokutywinwa, okanye idlale indima yesikhashana kuvavanyo;
I-flange eyimfama yenziwe ngokuphosa okanye ukudibanisa intambo okanye i-welding.Yiflange engenamingxuma embindini.Isetyenziselwa ikakhulu ukutywina isiphelo sangaphambili sombhobho, kunye nokutywina i-orifice yombhobho.Umsebenzi wayo ufana nentloko kunye nesigqubuthelo sombhobho, kwaye idlala indima ye-vibration yodwa kunye nokusika.Nangona kunjalo, i-blind flange seal sisixhobo sokutywina esisuswayo.Itywina lentloko alikakulungeli ukuvulwa kwakhona.I-flange eyimfama inokususwa ukuze iququzelele ukusetyenziswa kwakhona kombhobho kwixesha elizayo.
(2) Ngenxa yokuba i-flange ineempawu ezintle zokusebenza, idla ngokusetyenziswa ngokubanzi kubunjineli beekhemikhali, ukwakhiwa, i-petroleum, ucoceko, umbhobho, ukukhusela umlilo kunye nezinye iiprojekthi ezisisiseko;
Kuyimfuneko ukuseta amacwecwe ayimfama ekudibaneni kwezixhobo kunye nombhobho, ngokukodwa kwindawo yomda ngaphandle kwendawo yomda apho iipayipi zezinto eziphathekayo zenkqubo zixhunyiwe.Nangona kunjalo, kuvavanyo lwamandla emibhobho okanye uvavanyo lokutywinwa, akuvumelekanga ukusebenzisa iiplati ezingaboniyo ngexesha elifanayo njengesixhobo sokudibanisa (njenge-turbine, i-compressor, i-gasifier, i-reactor, njl.) kwinqanaba lokuqala lokulungiselela ukuqalisa.
Kodwa eneneni, kukho ukufana okuninzi phakathi kweeflange kunye neepleyiti eziyimfama zeflange.Ngokomzekelo, kukho iintlobo ezininzi zeendawo zokutywina, ezifana nenqwelomoya, i-convex, i-concave kunye ne-convex, i-tenon kunye ne-groove, kunye neendawo zokudityaniswa kweendandatho;Isetyenziselwa ukudibanisa i-flange, equlethwe ngamabini e-flanges, i-gasket kunye neebholiti ezininzi kunye namantongomane.I-gasket ibekwe phakathi kweendawo ezimbini zokutywina ze-flange.Emva kokuqinisa i-nut, uxinzelelo oluthile kwi-gasket surface lufikelela kwixabiso elithile, eliya kubangela i-deformation, kwaye iindawo ezingalinganiyo kwindawo yokutywina ziya kuzaliswa ukwenza uxhulumaniso luqine.
2. Ukufakwa kunye nokusetyenziswa kwepleyiti eyimfama yeflange
Ipleyiti eyimfama ye-flange inokudityaniswa ne-flange, oko kukuthi, i-gasket ibekwe phakathi kweendawo ezimbini zokutywinwa kwe-flange.Emva kokuba i-nut iqiniswe, uxinzelelo oluthile kwi-gasket surface lufikelela kwixabiso elithile, kwaye i-deformation iyenzeka, kunye neendawo ezingalinganiyo kwindawo yokutywina zizaliswe, ukwenzela ukuba uxhulumaniso luqine.Nangona kunjalo, ipleyiti eyimfama yeflange enoxinzelelo oluhlukeneyo inobunzima obahlukeneyo kwaye isebenzisa iibholiti ezahlukeneyo;Kwimeko yenkqubo ye-oyile ye-oyile, i-flange blind plate ayifuni ukuba ifakwe i-galvanized, kodwa kwimeko yezinye iinkqubo eziphakathi, i-flange blind plate iya kuba phantsi konyango olushushu lwe-galvanizing, ubunzima obuncinci be-zinc coating yi-610g / m2. , kunye nomgangatho wepleyiti yeflange eyimfama emva kokufakwa kwegalvanizing eshushu iya kuhlolwa ngokwemigangatho yelizwe.
Oku ngasentla ngumahluko phakathi kwe-flange kunye ne-blind flange kunye nokufakwa kunye nokusetyenziswa kwe-flange eyimfama.Ndiyathemba ukuba inokukunceda ukhethe kwaye ufake i-flange ngokuchanekileyo kwaye udlale indima yayo yokutywina.
