1. Ngokwendawo yei-flange enkuluNgaphambi kokulinganisa, umzobo we-flange ye-caliber enkulu yoqhagamshelo lwesixhobo ngasinye kufuneka utsalwe kuqala kwaye ufakwe iinombolo ngokulandelelana, ukwenzela ukuba ukulungiswa kunokufakwa ngokuhambelana nenani elihambelanayo, kunye nofakelo lunokwenziwa ngendlela ethile kunye nomgaqo. qinisekisa ukusebenza okuqhelekileyo.
2. Ngenxa yofakelo, i-flange enkulu yobubanzi inokuba nokwahlukana kwe-diameter yangaphandle, umlomo ongalunganga (intliziyo eyahlukileyo), ubukhulu be-gasket abulingani, ngoko ke ukulungiswa kwe-fixture kufuneka kuhambelane ne-flange yecala ayinakutshintshwa, ngoko ke umlinganiselo. yobungakanani kunye nenani lenxalenye nganye ngundoqo ekuqhutyweni nasekufakeni ukulungiswa.
3. Xa ulinganisa, kucetyiswa ukuba ulungelelanise abantu abathathu, ababini kubo ukuba balinganise, omnye ukuvavanya kwaye ugcwalise itafile, izixhobo zokulinganisa kunye ne-vernier calipers, ukuba akukho meko ekhoyo ngaphandle kwee-calipers kunye nerula yensimbi. Umlinganiselo ngumsebenzi ocokisekileyo, ngumba wofakelo lwezixhobo, umlinganiselo kunye nerekhodi kufuneka zilungiswe ukuze zichaneke, xa kuzaliswa itafile kufuneka kube nzulu kwaye kucace. Kumsebenzi wangempela wokulinganisa ukusebenzisana omnye nomnye, ngokuhambelana nomgaqo ochanekileyo wokubambisana nokusebenzisana.
4. Idatha elinganisiweyo kufuneka izaliswe kwitheyibhile.
I-flange enkulu yobubanziyenye yeeflange, esetyenziswa kakhulu kwaye ikhuthazwa kushishino loomatshini, ishishini lemichiza, ishishini lamandla omoya kunye noshishino lokucoca ugutyulo, kwaye yamkelwe kakuhle kwaye yathandwa ngabasebenzisi.I-flange enkulu yobubanziinoluhlu olubanzi losetyenziso. Inkqubo yokuvelisa ihlulwe ibe yi-rolling kunye ne-forging, kwaye i-flange enkulu inokugqithwa kuphela. Izinto eziphathekayo zentsimbi ye-carbon, insimbi engenasici kunye nentsimbi ye-alloy.

Iindidi zemveliso
Iiflange ezinkulu zobubanzizixhaphakileflat welding flangekwayebutt welding flange. Iiflange zeentambo zocingoazikho kumgangatho omkhulu. Kwimveliso yokwenene kunye neentengiso, okanye i-flat welding i-akhawunti yemveliso ye-welding enkulu. Ukuwelda okucabaiiflange ezinkulu zobubanzikwayei-butt welding enkuluububanzi be-flanges banesakhiwo esahlukileyo kunye noluhlu lokusetyenziswa, kwaye banokubonisa iimpawu ezahlukeneyo kunye neenzuzo, ngoko ke kuyimfuneko ukusebenzisa kuluhlu oluhlukeneyo ukuqinisekisa ukuba i-flange idlala indima ebalulekileyo. I-Flat welded flange enedayamitha enkulu inokuqina okungahambi kakuhle kwaye ilungele uxinzelelo P ≤4MPa.I-butt welding flange, eyaziwa ngokuba phezuluintamo flange, iqinile, ifanelekile kuxinzelelo oluphezulu kunye nezihlandlo zokushisa. Kukho iintlobo ezintathu zokutywinwa kobuso be-flange: ubuso bokutywina obucaba, obulungele uxinzelelo oluphantsi, iziganeko eziphakathi ezingenayo ityhefu; Umphezulu weconcave kunye neconvex yokutywina, ilungele iimeko zoxinzelelo oluphezulu; Umphezulu wokutywina weTenon kunye negroove, ilungele ukutsha, uqhushumbo, imidiya eyityhefu kunye nezihlandlo zoxinzelelo oluphezulu.Iiflangeyeepropati ezahlukeneyo zinemveliso elungileyo yokusebenza kwiinkalo ezahlukeneyo, kwaye umphumo uya kwahluka kwizihlandlo ezahlukeneyo kunye neZithuba.
