I-Flange (bona i-flange JBZQ 4187-97) ikwabizwa ngokuba yi-flange okanye i-flange.Amacandelo adibanisa umbhobho kumbhobho omnye komnye, afakwe kwiiphelo zombhobho.Kukho imingxuma kwi-flange, kwaye iibholiti zidibanisa ngokuqinileyo iiflange ezimbini.Iiflange zitywinwe nge-gaskets.Ukufakelwa kombhobho weFlange kubhekiselele kwiintambo zombhobho ezineflanges (iiflange okanye imihlaba).Inokuphoswa, ikrwelwe okanye idityaniswe.
Uxhulumaniso lwe-Flange (i-flange, i-joint) iqukethe i-flanges, i-gasket kunye neebholiti ezininzi kunye namantongomane.I-gasket ibekwe phakathi kweendawo zokutywina zeeflange ezimbini.Emva kokuba i-nut iqinisiwe, uxinzelelo oluthile kwi-gasket lufikelela kwixabiso elithile kwaye emva koko lukhubazeke, kwaye luzalise ukungalingani kwindawo yokutywina ukwenza uxhulumaniso luqine.Uqhagamshelwano lweFlange ludibaniso oluqhawukayo.Ngokwamacandelo adibeneyo, inokwahlulwa ibe yi-container flange kunye ne-pipe flange.Ngokohlobo lwesakhiwo, kukho i-flange edibeneyo, i-loop flange kunye ne-threaded flange.Iiflange ezidibeneyo eziqhelekileyo ziquka iiflange ze-welding flat kunye ne-butt welding flanges.I-flat welding flanges ine-rigidity embi kwaye ifanelekile kwizihlandlo apho uxinzelelo lwe-p≤4MPa.I-butt welding flanges, eyaziwa ngokuba yi-high neck flanges, inokuqina okuphezulu kwaye ifanelekile kwizihlandlo ezinoxinzelelo oluphezulu kunye nobushushu.
Kukho iindlela ezintathu zomphezulu wokutywina we-flange: umphezulu wokutywina osicaba, olungele iimeko ezinoxinzelelo oluphantsi kunye ne-non-toxic medium.Umphezulu wokutywina weconcave-convex, olungele iimeko ezinoxinzelelo oluphezulu kancinci, imithombo yeendaba enetyhefu kunye nezihlandlo zoxinzelelo oluphezulu.I-gasket yindandatho eyenziwe ngezinto ezinokuvelisa i-deformation yeplastiki kwaye inamandla athile.Uninzi lwee-gaskets zinqunywe kwiiplate ezingezizo zetsimbi, okanye zenziwe ngamafektri aqeqeshiweyo ngokobukhulu obuchaziweyo.Izinto ezisetyenziswayo ziipleyiti zerabha zeasbestos, iipleyiti zeasbestos, iipleyiti zepolyethylene, njl.Kukho kwakhona i-gasket enentsimbi eyenziwe ngezinto ezisongelweyo ezingeyintsimbi.kukwakho negasket yesilonda eyenziwe ngemicu yentsimbi ebhityileyo kunye nemicu yeasbestos.Iigaskets eziqhelekileyo zerabha zifanelekile kumathuba 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.Phakathi, eyona isetyenziswa ngokuqhelekileyo yibhodi yeasbestos enganyangekiyo kwiasidi.Kwizixhobo zoxinzelelo oluphezulu kunye nemibhobho, i-lens-shaped metal or other-shaped metal gaskets 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.
Ukuhlelwa kweFlange: Iiflange zihlulwe zibe yimisonto (eneentambo) kunye ne-welding flanges.I-diameter encinci ye-low-pressure ine-flange yocingo, kwaye i-high-pressure kunye ne-low-pressure diameters enkulu isebenzisa i-welding flanges.Ubuninzi beplate ye-flange yeengcinezelo ezahlukeneyo kunye nobubanzi kunye nenani leebholiti zokudibanisa ziyahluka.Ngokwamanqanaba ahlukeneyo oxinzelelo, iipads ze-flange nazo zinezixhobo ezahlukeneyo, ukusuka kwi-low-pressure asbestos pads, iipads ze-asbestos eziphezulu ukuya kwiintsimbi zetsimbi.
1. Ukwahlula ngezinto eziphathekayo kwi-carbon steel, insimbi ephosiweyo, insimbi yensimbi, insimbi engenasici, ithusi, i-aluminium alloy, iplastiki, i-argon, i-ppc, njl.
2. Ngokwendlela yokuvelisa, inokuthi ihlulwe ibe yi-flange edibeneyo, i-flange ephosiweyo, i-welding flange, i-flange eqengqelekayo (imodeli engaphezulu) 3. Ngokomgangatho wokuvelisa, inokwahlulwa ibe ngumgangatho wesizwe (umgangatho woMphathiswa weMichiza). Ishishini, umgangatho wepetroleum, umgangatho wamandla ombane) , uMgangatho waseMelika, uMgangatho waseJamani, uMgangatho waseJapan, uMgangatho waseRashiya, njl.
Iinkqubo ezininzi zemigangatho yeflange yemibhobho yamazwe ngamazwe:
1. Ukudibanisa i-Flange okanye i-flange joint ibhekisela kwikhonkco eligotywayo elibandakanya ii-flanges, ii-gaskets kunye neebholiti ezidityanisiweyo njengesakhiwo sokutywinwa esidibeneyo.Iiflange zemibhobho zibhekisa kwiiflange ezisetyenziselwa imibhobho kufakelo lwemibhobho.Kwisixhobo, sibhekisa kwi-inlet kunye ne-outlet flanges yesixhobo.
