Qhov sib txawv ntawm Cast Flanges thiab Dig Muag Flanges
Cov ntsiab lus tseem ceeb thiab cov qauv sib txawv
Txhais
Lub nplhaib- zoo li cov khoom sib txuas nrog lub qhov ntsia hlau siv nyob rau hauv cov kav hlau kav hlau los koom nrog cov kav dej, li qub, twj thiab lwm yam khoom siv. Yuav tsum tau ua ke nrog ib tug mating flange, nrog sealing tiav los ntawm ib tug gasket ntawm lawv
Cov yam ntxwv zoo
Lub cev tseem ceeb muaj xws li lub voj voog uas muaj qhov sib npaug ntawm qhov sib npaug (tus lej txiav txim siab los ntawm cov yeeb nkab txoj kab uas hla, piv txwv li, DN100 flanges feem ntau muaj 8 bolt qhov). Sab hauv sab hauv suav nrog lub qhov (socket) lossis lub qhov (spigot) sib piv cov yeeb nkab txuas hom (hloov rau cov yeeb nkab hlau txuas txuas). Lub disc nto yog tiaj tus nrog ib tug tshwj xeeb sealing groove (kom haum cov roj hmab, asbestos, los yog lwm yam gaskets), tag nrho cov qauv yog 'ntiv nplhaib-zoo li tus thiab qhib', nrog ib tug central bore txuam cov yeeb nkab txoj kab uas hla los xyuas kom meej unimpeded ntws ntawm nruab nrab.
Txhais
Ib lub flange- hom haum siv los kaw qhov kawg ntawm cov kav hlau txuas, tiv thaiv qhov ntws ntawm qhov nruab nrab. Nws tsis tas yuav mating flange thiab tuaj yeem ua tiav sealing ntawm cov yeeb nkab kawg ntawm nws tus kheej.
Cov yam ntxwv zoo
Ib yam li lub nplhaib-zoo li tus disc nrog lub qhov ntsia hlau tau muab faib thoob plaws hauv nws lub ntsej muag (tus naj npawb thiab txoj kab uas hla ntawm cov flanges rau cov kav dej ntawm tib qhov kev qhia tshwj xeeb, ua kom muaj kev sib txuas ncaj qha nrog cov yeeb nkab flanges). Txawm li cas los xij, nws tsis muaj qhov nruab nrab aperture, es tsis txhob siv cov khoom siv disc (nrog lub ntsej muag tiaj tus los yog cov hlua txuas ntxiv los txhim kho lub siab ua haujlwm). Ib qho kev sib khi hauv qhov zawj (rau muab cov sealing gaskets) tuaj yeem muab tso ua ke. Tag nrho cov qauv yog 'ntiv nplhaib-zoo li tus thiab khov', nrog rau nws cov haujlwm tseem ceeb yog los thaiv kev nkag thiab tawm ntawm cov xov xwm hauv cov kav dej.
Kev ua haujlwm txawv
Ductile Iron Cam khwb cia Flanges: 'Kev Sib Txuas thiab Flow'
Cov haujlwm tseem ceeb yog kev sib txuas thiab ntws txuas ntxiv: siv rau kev sib txuas sib txuas ntawm cov kav dej hlau, thiab nruab nrab ntawm cov kav dej thiab cov khoom siv (xws li li qub, ntws ntsuas, twj), thaum ua kom tsis muaj kev cuam tshuam ntawm kev tshaj tawm (dej, dej phwj tuaj, thiab lwm yam) hauv cov kav dej tsis muaj kev cuam tshuam kev sib kis.
Cov ntawv thov ib txwm: Flange pob qij txha rau segmented pipeline kev sib txuas nyob rau hauv ntev - cov dej xa mus deb; kev sib txuas ntawm cov kav dej thiab cov cuab yeej tswj tau zoo li lub rooj vag li qub lossis kos li qub; cov nodes xav tau kev saib xyuas yav tom ntej lossis hloov khoom siv (xws li cov kav dej nkag / qhov hluav taws xob ntawm cov chaw nres tsheb).
Ductile Iron Dig Muag Flange: 'Sealing thiab Thaiv'
Cov haujlwm tseem ceeb yog kev sib txuas thiab ntws txuas ntxiv: sealing thiab thaiv. Siv rau ntawm qhov kawg ntawm cov kav hlau kav hlau, cov kav hlau tsis siv cov chaw nres nkoj, lossis rau kev kaw cov kav dej ib ntus thaum kho cov khoom siv. Tiv thaiv cov pa nruab nrab thiab cov kab mob sab nraud los ntawm kev nkag mus rau hauv cov raj xa dej, ua kom tag nrho cov dej ntws nruab nrab.
Cov ntawv thov: Kev sib khi tas mus li ntawm qhov kawg ntawm cov dej xa hluav taws xob (piv txwv li, thaum cov kev sib txuas tshwj xeeb tseem tsis tau siv); sealing ob qhov kawg ntawm ntu tos kev kho thaum lub sij hawm kho kav dej kom tsis txhob muaj xov xwm dhau mus; Kev sib khi ib ntus ntawm cov chaw nres nkoj kav dej tom qab cov khoom siv (xws li cov twj tso kua mis lossis cov lim dej) tshem tawm.
Installation thiab Compatibility sib txawv
Yeeb Nkab Flange Installation Method
Yuav tsum tau ua ke nrog lwm qhov flange ntawm cov lus qhia zoo ib yam (pipe flange lossis khoom flange). Lub sealing gasket yog muab tso rau nruab nrab ntawm lawv, ruaj ntseg los ntawm bolts threaded los ntawm lub bolts qhov ntawm ob lub flanges thiab nruj nreem kaw los tsim ib tug kaw kev twb kev txuas. Thaum lub sij hawm installation, xyuas kom meej lub flange ntsej muag nyob rau hauv parallel thiab bolts yog tus sib npaug tensioned.
Qhov muag tsis pom Flange Installation Method
Yuav tsum tau tsuas yog txuas rau flange ntawm cov yeeb nkab kawg (los yog cov yeeb nkab flange interface). Lub sealing gasket yog nyob nruab nrab ntawm lub qhov muag tsis pom flange thiab cov yeeb nkab flange, ruaj ntseg los ntawm bolts yam tsis tas yuav tsum tau ntxiv mating flange, uas ua rau lub installation yooj yim dua.
Kev siv yeeb nkab Flange
Haum rau txhua daim ntawv thov uas xav tau 'kev sib txuas + ntws', tshwj xeeb tshaj yog nyob rau hauv cov ntu txuas txuas ntxiv ntawm cov kav dej thiab cov khoom sib txuas cov ntsiab lus. Yuav tsum phim cov kav dej hauv txoj kab uas hla thiab qhov ntsuas siab (piv txwv li, PN1.0MPa, PN1.6MPa siab ntsuas yuav tsum ua raws li cov kav dej thiab cov khoom siv tshwj xeeb).
Qhov muag tsis pom Flange Applications
Tsuas yog rau 'sealing' daim ntawv thov. Yuav tsum zoo kawg nkaus phim cov yeeb nkab flange specifications (xws li txoj kab uas hla, bolt qhov suav / txoj kab uas hla, qhov ntsuas siab) kom ntseeg tau tias kev sib khi ruaj khov thiab tiv thaiv kom tsis txhob cuam tshuam los ntawm cov khoom tsis sib xws (xws li DN200 pipeline flanges xav tau DN200 dig muag flanges).
Common Material Properties thiab Performance
Ob leeg siv cov khoom siv hlau ductile, muaj cov txiaj ntsig zoo ib yam
Siab zog thiab toughness
Muaj peev xwm tiv taus cov raj xa dej ua haujlwm siab (piv txwv li, 0.6-1.6 MPa), ua kom haum rau cov kev cuam tshuam sab nraud xws li av compression thiab hauv paus kev daws teeb meem.
Corrosion Resistance
Feem ntau siv cov tshuaj tiv thaiv zoo ib yam - kev kho corrosion raws li cov kav dej hlau (xws li, zinc txau sab nraud + asphalt xim, sab hauv cement mortar txheej) kom tiv taus av thiab dej corrosion.
Durability
Tsim los rau lub neej ua haujlwm sib piv cov kav hlau kav hlau (tshaj 50 xyoo), ua tau raws li qhov ntev - lub sijhawm ua haujlwm ntawm cov kav dej.
