Flange yog cov khoom kho vajtse. Nws lub hom phiaj yog los txuas cov kav dej, cov qog los yog cov hlau hollow zoo sib xws ntawm cov duab cylindrical. Txhawm rau kom ruaj khov thiab ruaj ntseg txuas ob yam khoom, koj yuav tsum tau siv cov ntaub mos muag ntxiv. Cov ntaub ntawv mos yog siv rau lawv cov khoom siv. Thiab rau lo lus nug: "Flange - dab tsi nthuav dav yog qhov no?" - koj tuaj yeem teb tau tias qhov no yog cov khoom siv kho vajtse (luv luv rau "cov khoom siv hlau"), uas tsim kom muaj kev sib khi zoo ntawm qhov sib txuas ntawm cov ntsiab lus cylindrical.
Device
Txheem flanges zoo li lub nplhaib hlau nrog lub qhov tshwj xeeb rau cov studs lossis bolts. Ntawm qee yam ntawm cov ntsiab lus no tej zaum yuav muaj kev tawm tsam, kev nyuaj siab, spikes, grooves.
Flange ntau lawm
Ntau qib steel yog siv rau kev tsim khoom: 13XFA, 20/09G2S, 12X18H10T, 15X5 M thiab lwm yam. Tsis tas li ntawd, lawv tuaj yeem ua hlau thiab stainless. Cov cuab yeej siv yog txawv. Manufacturers siv forging, stamping, casting. Rau txhua txoj kev, cov cuab yeej tshwj xeeb thiab cov pwm yog siv. Los ntawm kev tso koj cov khoom,manufacturers ua tib zoo xyuas nws kom zoo. Siv cov kev ntsuam xyuas tshwj xeeb hauv lawv txoj haujlwm, QCD cov neeg ua haujlwm tshawb xyuas lawv kom ruaj khov thiab kev ntseeg tau. Flanges tseem raug kuaj xyuas kom tsis txhob ya raws. Nws yog dab tsi? Txij li thaum lawv yog cov fasteners thiab koom nrog hauv kev sib txuas cov khoom hlau uas tuaj yeem sib cuag nrog dej, nws yog ib qho tseem ceeb uas lawv tsis raug rau corrosion. Tias yog vim li cas siv cov hlau tsis muaj dej tsis zoo. Feem ntau, cov chaw tsim khoom npog qhov chaw ntawm flanges nrog cov txheej txheem tiv thaiv ntxiv.
Type of flanges
Yog li, flange - nws yog dab tsi? Qhov no yog, ua ntej ntawm tag nrho cov, kho vajtse. Nyob ntawm daim ntawv thov, cov khoom no tuaj yeem tiaj tus, dab tshos, dawb. Tus qauv tsim tsis txawv ntau. Nyob rau hauv dab tshos flanges muaj ib tug me me protrusion zoo li lub khob hliav qab. Nws feem ntau hu ua dab tshos. Hom flange no yog siv thaum nws tsim nyog rau vuam qhov kawg-rau-kawg. Qhov no protrusion pab kom nruj txuas cov txuas txuas ntawm cov kav dej. Lawv kuj tsim nyog thaum cov kav dej txuas nrog cov tso tsheb hlau luam lossis lwm yam khoom siv. Lub ntsiab kom zoo dua ntawm xws li flanges yog tias lawv tuaj yeem siv tau ob peb zaug. Cov khoom siv no yog tsim los ntawm cov khoom siv ruaj khov, thiab qhov no tso cai rau lawv siv rau hauv kev ua haujlwm qhov kub ntawm -253 txog +600 degrees Celsius.
Flat flange - yog dab tsi? Qhov no yog ib qho khoom siv uas zoo li lub tiaj tus disk nrog qhov. Nws yog siv thaum txuasqhov chaw ntawm fittings, shafts, hlab ntsha, pipelines, khoom siv thiab lwm yam. Nrog rau cov khoom no, qhov chaw ntawm cov kav dej tuaj yeem kho kom nruj.
Loose flange - yog dab tsi? Hom no tsis txawv ntau ntawm cov saum toj no. Nws muaj ob feem: ib tug pa flange thiab ib lub nplhaib. Nws yog ib qho tseem ceeb uas lawv tau ua los ntawm tib cov khoom thiab muaj tib txoj kab uas hla thiab siab. Lawv siv qhov chaw ua haujlwm nyuaj tshaj plaws, qhov twg nws nyuaj rau kev teeb tsa. Vim yog ob feem, kev sib txuas yuav nruj thiab ruaj khov. Ua ntej, lub flange tsis tu ncua txuas nrog (nws yog welded), thiab lwm lub nplhaib tuaj yeem tig tau nyab xeeb thaum ua haujlwm.
Lwm yam kev faib tawm
Cov ntsiab lus tshwj xeeb tau tsim rau qee hom haujlwm. Tshwj xeeb flange - yog dab tsi? Cov no yog cov khoom siv tib yam, tab sis txhawm rau ua kom qee qhov haujlwm yooj yim, lawv cov qauv tsim tau hloov kho me ntsis. Lawv tuaj yeem raug welded, xoob, cam khwb cia, threaded. Tsuas yog grooves raug txiav tawm ntawm lawv los yog protrusions yog welded. Rau lawv cov chaw tsim khoom, cov duab kos tshwj xeeb yog thawj zaug tsim thiab cov pwm raug nrum. Cov khoom siv zoo li no yog tsim los ntawm kev lag luam.
