Nyob rau hauv cov kav dej nyiaj siv ua haujlwm ntawm cov nroj tsuag petrochemical, thaum siab -kub xov xwm ntws los ntawm 90-degree khoov, tus kheej qhov hnyav ntawm cov kav dej thiab thermal expansion stress feem ntau ua rau kev txhawb nqa kom deform lossis txawm tias xau. Nyob rau hauv qhov tseem ceeb juncture no, lubob chav flange 90℃duck ko taw khoovsawv tawm los ua ib qho tseem ceeb hauv kev daws teeb meem engineering. Nws cov qauv tsim tshwj xeeb ua ke nrog kev sib txuas flange nrog duck- kev txhawb nqa ko taw. Cov yeeb nkab haum no tsis tsuas yog redirects qhov ntws ntawm qhov nruab nrab tab sis kuj txhawb nqa loads, ua hauj lwm raws li "kev sib koom ruaj khov" ntawm cov kav dej. Nws zoo hloov cov kev taw qhia ntws thaum faib cov khoom thauj los ntawm nws cov qauv kev txhawb nqa hauv qab. Qhov kev tsim qauv no ua rau muaj txiaj ntsig zoo hauv engineering, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej nyuaj xws li kev kub siab thiab kev co.
1. Cov Ntsiab Lus thiab Cov Qauv
Covob chav flange 90℃duck ko taw khoovyog ib hom yeeb nkab haum nyob rau hauv industrial pipeline systems, muaj npe tom qab nws cov tsos:
"Ob chav flange": Ob qhov kawg yog nruab nrog flanges, txuas nrog cov kav dej lossis cov khoom siv ntawm bolts kom yooj yim installation, disassembly, thiab sealing.
"90℃Duck Foot Khoov": Lub cev tseem ceeb yog lub luj tshib 90-degree, nrog cov qauv kev txhawb nqa zoo li "duck taw" txuas mus rau hauv qab kom sib koom cov raj xa dej hnyav thiab kev ntxhov siab, txhim kho kev ruaj ntseg.
2. Core Functions thiab Application Scenarios
Functional Features
Kev sib txuas lus: Ua tiav 90℃redirection, yoog mus rau cov kav dej layouts.
Load-kev txhawb nqa: Cov qauv hauv qab "duck foot" tuaj yeem kho rau hauv av lossis txhawb nqa, txo qis deformation thiab vibration los ntawm tus kheej - nyhav, nruab nrab ntws, lossis thermal expansion.
Txhim khu kev sealing: Qhov ob -flange tsim, ua ke nrog gaskets, haum rau siab -siab, siab- kub, lossis corrosive media.
Daim ntawv thov teb
Cov kav dej muaj xws li petrochemical, roj av, hluav taws xob, metallurgy, thiab dej thiab dej.
Cov xwm txheej ib txwm muaj xws li kev txhawb nqa ntawm cov kav dej siv hluav taws xob, tuav cov kav xa dej nrog cov khoom hnyav, thiab tswj cov inlets lossis qhov hluav taws xob ntawm cov khoom siv vibrating xws li twj thiab compressors.
3. Kev teeb tsa thiab kev saib xyuas cov ntsiab lus tseem ceeb
Installation Notes
Positioning Calibration: Xyuas kom cov duck ko taw txhawb nqa saum npoo yog kab rov tav thiab flanges yog perpendicular rau cov kav dej axis kom tsis txhob muaj qhov sib npaug ntawm qhov ntsia hlau.
Txhawb Kev Kho: "Duck taw" yuav tsum tau muab tso rau hauv lub hauv paus pob zeb lossis cov qauv hlau los ntawm cov ntsia hlau thauj tog rau nkoj, sib piv cov raj xa dej thauj khoom -cov kabmob muaj peev xwm.
Kev kho mob sealing: Xaiv cov gaskets uas tsim nyog, xws li kauv qhov txhab thiab roj hmab, ntawm flange sib txuas. Tighten bolts uniformly rau lub torque teev.
Kev kho thiab tshuaj xyuas
Tsis tu ncua xyuas cov dej xau ntawm flanges thiab tawg deformation hauv cov qauv kev txhawb nqa.
Nyob rau hauv ib puag ncig corrosive, saib xyuas cov khoom siv corrosion thiab siv los tiv thaiv -corrosion txheej raws li xav tau.
4. Cov ntsiab lus tseem ceeb
Nominal Diameter (DN): Feem ntau ntawm DN25 txog DN1200, nrog rau qhov ntau thiab tsawg muaj.
Kev ntsuas siab: Ua raws li ANSI, API, JIS, GB, thiab lwm yam, cov chav kawm sib xws, PN16, PN25, Class150, Class300.
Khoom siv: Carbon steel, stainless hlau, hlau alloy, los yog cov ntaub ntawv tshwj xeeb rau cov yam ntxwv nruab nrab.
5. Qhov sib txawv ntawm lwm cov yeeb nkab fittings
vs. Ordinary 90℃luj tshib: Lub luj tshib zoo ib yam tsis muaj kev txhawb nqa, xav tau cov hlua ntxiv; duck ko taw khoov sib koom ua ke kev txhawb nqa kom txo qis kev teeb tsa.
vs. Expansion Bends: Expansion khoov tsom rau thermal deformation them, thaum duck ko taw khoov ua ntej thauj khoom -cov kabmob thiab kev hloov pauv- ob qho tib si tuaj yeem ua ke rau cov xwm txheej nyuaj.
6. Kev Xaiv Cov Khoom Siv Siv
Cov khoom nruab nrab (kub, siab, corrosiveness);
Pipeline system load yuav tsum (tus kheej- hnyav, nruab nrab hnyav, kev co);
Qhov chaw nruab thiab kev txhawb nqa;
Cov qauv kev lag luam thiab kev ua raws cai (xws li, daim ntawv pov thawj tshwj xeeb rau cov khoom siv tshuaj lom neeg / petrochemical).
Lub hauv paus tsim ntawm lubob chav flange 90℃duck ko taw khoovlus dag nyob rau hauv kev koom ua ke redirection thiab kev txhawb nqa, haum rau industrial pipelines yuav tsum tau ruaj khov load- bearing. Thaum xaiv thiab teeb tsa, ua raws cov kev ua haujlwm tsis zoo thiab cov qauv kom ntseeg tau tias muaj kev nyab xeeb. Nyob rau hauv cov qauv ntawm kev txawj ntse, ntev - voj voog kev lag luam pipeline tes hauj lwm, xws li fittings integrated symbolize tsis tsuas mechanical Cheebtsam tab sis kuj lub epitome ntawm kev ntseeg tau tsim nyob rau hauv pipeline systems.
