Lub ntaws dej ntawm lub qhov rais flange yog cov tiaj tiaj, thiab qhov chaw sib txuas nrog cov roj gas loj. Tom qab preloading, lub gasket yog yooj yim mus cuag los yog txav mus rau ob sab. Cov khoom ntim ntawm cov flange yog cov neeg pluag, thiab nws tsuas yog haum rau cov neeg tsis tshua muaj siab.
Lub ntsiab ntau cov tshuab fais fab ntawm cov khoom fais fab yog raws li nram no:
Lub tswv yim tseem ceeb ntawm kev tawm flange yog forging, casting, txiav thiab dov.
Lub flange flange muaj meej duab thiab loj, me me thiab nyiaj tsawg, tab sis nws tau casting defects (pore, nrib pleb, menyuamuas); lub puab tsaig ntawm lub casting yog tsis muaj kev ncaj ncees (yog tias nws yog ib qho kev txiav, qhov txawv ntawm qhov raug ploj lawm);
Forged flange muaj tsawg cov ntsiab lus, tsis muaj xeb dua li flange casting, zoo streamlined forging, compact qauv thiab zoo dua mechanical zog dua cam flange.
Kev txhim kho cov txheej txheem yuav ua rau cov loj lossis tsis sib txig, cov nplaum txhaws thiab cov nqi qis dua qhov kev flange.
Kev zam txim tuaj yeem ua tau ntau dua shear thiab tensile rog dua castings.
Qhov zoo ntawm cov castings yog tias lawv tuaj yeem tsim ntau ntau cov qauv thiab txo tus nqi.
Qhov zoo ntawm kev ntaus nqi yog tias nws cov qauv hauv kev yog yam tsis zoo thiab tsis muaj teeb meem xws li tshuab nqus hlau thiab cov menyuam nyob hauv qhov casting.
Qhov txawv ntawm casting flange thiab forging flange yuav txawv los ntawm cov txheej txheem ntau lawm, piv txwv li, centrifugal flange yog ib hom ntawm flange casting.
Centrifugal flange yog ib hom flange uas ua los ntawm precision casting txujci. Piv nrog cov xuab zeb ntau, qhov txuj ci no tau muaj cov qauv zoo dua thiab zoo dua. Nws tsis yog yooj yim kom muaj cov kab xoob, pore thiab trachoma.
