Iiflange zokwenziwaziyilwa ngesiseko sesamenteiiflange zentsimbi, yaye ukomelela kwawo kuphakame kakhulu kunokutyhilwaiiflange zentsimbi, ukwenzela ukuba iindawo ezidibeneyo kunye nemibhobho zixhunywe ekupheleni kombhobho.I-butt welding flangeluhlobo lokufakela umbhobho, elibhekiselele kwi-flange enentamo kunye nokutshintshwa kombhobho ojikelezayo kunye nokudibanisa i-welding ye-butt kunye nombhobho. Akulula ukuguqulwa, ukutywinwa okulungileyo, ukusetyenziswa ngokubanzi, okufanelekileyo kuxinzelelo okanye ukuguquguquka kobushushu bemibhobho okanye ubushushu obuphezulu, uxinzelelo oluphezulu kunye nemibhobho yokushisa ephantsi, inzuzo ingabizi, uxinzelelo oluncinci aludluli kwi-2.5mpa; Ikwasetyenziselwa ukuhambisa imidiya ebizayo, enokutsha kunye neqhuma kumbhobho, kwaye uxinzelelo lwegama lumalunga ne-PN16MPa.
Iyenzekileiiflange zinemingxuma, kwaye iibholiti (ezibandakanya intloko kunye nezijija) zibambe iiflange ezimbini kunye. Iiflange ezibunjiweyo zitywinwe nge-gaskets.Yenziwe iflenjiizixhobo zombhobho zibhekisa kwabo baneiiflange ezibunjiweyo (iiflangeokanye amalungu). Isenokuphoswa, idityaniswe okanye idityaniswe. Uxhulumaniso lwe-flange luqukethe i-pair of flanges, i-gasket kunye nenani leebholiti kunye namantongomane. I-gasket ibekwe phakathi kweendawo zokutywinwa kweeflange ezimbini, kwaye emva kokuqinisa i-screw mother, uxinzelelo oluthile oluphezu kwe-gasket luphazamiseka emva kokufikelela kwixabiso elithile, kwaye indawo engalinganiyo kwindawo yokutywinwa izaliswe, ukuze uqhagamshelwano luqinile kwaye aluvuzi.

Kukho iintlobo ezintathu zokutywina umphezulu wokutywina we-flange: umphezulu wokutywina wendiza, ofanelekileyo kuxinzelelo olungekho phezulu, oluphakathi (into egqibayo) iziganeko ezingenayo ityhefu; Umphezulu weconcave kunye neconvex yokutywina, ilungele iimeko zoxinzelelo oluphezulu kancinci; Umphezulu wokutywina we-tenon (S ǔ N) umsele, ulungele ukutsha, uqhushumbo, indawo eyityhefu kunye nezihlandlo zoxinzelelo oluphezulu. I-Gasket yindandatho eyenziwe ngezinto eziphathekayo ezinokuvelisa i-deformation yeplastiki kwaye inamandla athile.
Uninzi lweegaskets zisikwe phantsi kwiipleyiti ezingezizo ezentsimbi, okanye zenziwe ziifektri eziqeqeshiweyo ngokobungakanani obuchaziweyo (GU ī ding), iMaterial yibhodi yeRubha yeasbestos, ibhodi yeasbestos, ibhodi yepolyethylene, njl. , insimbi engenasici) i-asbestos kunye nezinye izinto ezingezizo zetsimbi ezifakwe kwi-gasket yensimbi; Kukwakho nohlobo lwegasket ejikajikayo eyenziwe ngebhanti yentsimbi encinci kunye nebhanti yeasbestos kunye. I-flange ikwabizwa ngokuba yi-flange flange. Inxalenye edibanisa umbhobho kumbhobho ixhunywe ekupheleni kombhobho. Kukho imingxuma kwiflange kwaye iibholiti zibambe iiflange ezimbini kunye. Gasket izitywina phakathi flanges. I-Flange yinxalenye yedisk-shaped, exhaphake kakhulu kubunjineli bombhobho. Iiflange zisetyenziswa ngababini.

Kubunjineli bombhobho, i-flange isetyenziselwa ukudibanisa umbhobho. Ekugqibeleni apho iibhobho ezimbini zifuna ukuxhunywa, faka i-flange nganye. I-wire flange ingasetyenziselwa imibhobho yoxinzelelo oluphantsi, kunye ne-welded flange ingasetyenziselwa uxinzelelo olungaphezu kwe-4 kg. Beka i-gasket phakathi kweeflaneli ezimbini kwaye uzibophe phantsi. Abavelisi be-Flange bahlala besebenzisa iibholiti ukudibanisa iinqwelomoya ezimbini kwi-periphery ngexesha elifanayo iindawo zokudibanisa ezivaliweyo, ezibizwa ngokuba yi "flange", ezifana noqhagamshelwano lombhobho wokungenisa umoya, olu hlobo lwamacandelo lunokuthiwa "i-flange parts". I-gasket yerabha eqhelekileyo ilungele ithuba apho ubushushu bungaphantsi kwe-120 ℃; I-asbestos gasket yerabha ilungele umphunga wamanzi (ekubhekiselwa kuwo njengomphunga wamanzi) iqondo lobushushu lingaphantsi kwe-450 ℃, ubushushu be-oyile bungaphantsi kwe-350 ℃, uxinzelelo lungaphantsi kwezihlandlo ezi-5MPa, kumbindi we-corrosive jikelele (dlala indima ethatha isigqibo kwizinto eziphathekayo. ), kusetyenziswa ipleyiti yeasbestos exhathisa iasidi. Kwizixhobo zoxinzelelo oluphezulu (SHEBEI) kunye nemibhobho, i-gaskets yensimbi yobhedu, i-aluminium (Al), no. Intsimbi eyi-10, insimbi engenasici (insimbi engenasici) eyenziwe nge-lens (ukuhlelwa: i-lens yeplastiki kunye neglasi ezimbini iintlobo) okanye ezinye iimilo. Ububanzi boqhagamshelwano lwe-gasket yoxinzelelo oluphezulu kunye nokutywinwa komhlaba kuncinci kakhulu (uqhagamshelwano olusondeleyo), kwaye ukugqitywa kokulungiswa kwendawo yokutywinwa kunye ne-gasket iphezulu.
