I-Welding Flange
I-flange ikwabizwa ngokuba yi-flange okanye i-flange.
Inxalenye edibanisa umbhobho kunye nombhobho omnye komnye ixhunywe ekupheleni kombhobho.Kukho imingxunya kwiiflange, kwaye iibholithi zenza ukuba iiflange ezimbini zidityaniswe ngokuqinileyo.Iiflange zitywinwe ngee-gaskets.Izixhobo zombhobho ophothiweyo zibhekisela kwimibhobho efakelwayo eneflange (iilugi okanye iziseko).Ingenziwa ngokuphosa (engaboniswanga emfanekisweni), okanye inokubunjwa ngokuqhagamshelwa kwentambo okanye i-welding.Uxhulumaniso lweFlange (i-flange, i-joint) iqulethe i-flanges, i-gasket kunye neebholiti ezininzi kunye namantongomane.I-gasket ibekwe phakathi kweendawo zokutywina zeeflange ezimbini.Emva kokuqinisa i-nut, uxinzelelo oluthile kwi-gasket surface lufikelela kwixabiso elithile kunye nokukhubazeka kwaye luzalise ukungalingani kwendawo yokutywinwa ukuze wenze uxhulumaniso lube lukhuni kunye nobungqina bokuvuza.Uqhagamshelwano lweFlange ludibaniso oluqhawukayo.Ngokwamacandelo adibeneyo, inokwahlulwa ibe yi-container flange kunye ne-pipe flange.Ngokohlobo lwesakhiwo, kukho iiflange ezidityanisiweyo, iiflange ezikhululekileyo kunye neeflange ezinentambo.Iiflange ezidibeneyo eziqhelekileyo ziquka iiflange ze-welding flat kunye ne-butt welding flanges.I-flat-welded flanges ine-rigidity embi kwaye ifanelekile kwizihlandlo ezinoxinzelelo p≤4MPa;I-butt-welded flanges ikwabizwa ngokuba yi-high-neck flanges enobulukhuni obukhulu kwaye ifanelekile kwiimeko ezinoxinzelelo oluphezulu kunye nobushushu.Zintathu iindidi zokutywinwa komphezulu weflange: umphezulu wokutywina osicaba, olungele iimeko ezinoxinzelelo oluphantsi kunye nemidiya engeyiyo ityhefu;umphezulu wokutywina weconcave-convex, olungele iimeko ezinoxinzelelo oluphezulu kancinci;ulwimi kunye ne-groove yokutywina indawo, ilungele ukutsha kunye nokuqhuma , Imidiya ye-Toxic kunye nezihlandlo zoxinzelelo oluphezulu.I-gasket yindandatho ejikelezayo eyenziwe ngezinto ezinokuvelisa i-deformation yeplastiki kwaye inamandla athile.Uninzi lwee-gaskets zinqunywe kwiiplate ezingezizo zetsimbi, okanye zenziwe ngamafektri aqeqeshiweyo ngokobukhulu obuchaziweyo.Izinto eziphathekayo ngamacwecwe erabha ye-asbestos, iipleyiti ze-asbestos, iiplate ze-polyethylene, njl.;iipleyiti zetsimbi ezibhityileyo (intsimbi emhlophe, insimbi engagqwali) nazo zisetyenziselwa ukususa i-asbestos I-gasket ehlanganiswe ngentsimbi eyenziwe ngezinto ezingezizo;kukwakho ne-spiral inxeba gasket eyenziwe ngeteyiphu yentsimbi ecekethekileyo kunye ne-asbestos tape.Iigaskets eziqhelekileyo zerabha zifanelekile kwiimeko apho ubushushu bungaphantsi kwe-120 ° C;iigaskets zerabha ye-asbestos zilungele iimeko apho ubushushu bomphunga wamanzi bungaphantsi kwama-450°C, ubushushu be-oyile bungaphantsi kwama-350°C, kwaye uxinzelelo lungaphantsi kwe-5MPa, kwaye ludla ngokudlaka.Eyona ndlela isetyenziswa kakhulu yibhodi yeasbestos enganyangekiyo ngeasidi.Kwizixhobo zoxinzelelo oluphezulu kunye nemibhobho, i-gaskets yensimbi yohlobo lwe-lens okanye ezinye iimilo ezenziwe ngobhedu, i-aluminium, i-10 yensimbi, kunye nensimbi engenasici.Ububanzi boqhagamshelwano phakathi kwe-gasket yoxinzelelo oluphezulu kunye nomgangatho wokutywinwa kuncinci kakhulu (uqhagamshelwano lomgca), kunye nokugqitywa kokulungiswa kwendawo yokutywinwa kunye ne-gasket iphezulu.
I-flange yohlulwe ibe yintambo edibeneyo (uxhumo lwentambo) i-flange, i-welding flange kunye ne-clamping flange.Kukho i-wire flanges kunye ne-ferrule flanges ye-low-pressure diameters encinci.Iiflange ezidityanisiweyo zisetyenziselwa uxinzelelo oluphezulu kunye noxinzelelo oluphantsi lweediameters ezinkulu.Ubunzima beeflange kunye nobubanzi kunye nenani leebholiti zokudibanisa zihluke kwiingcinezelo ezahlukeneyo.
