Lub cev hlau forged valve (Machined part)

Lub cev valve no yog lub ntsiab tivthaiv ntawm cov valve tswj hauv cov kav dej kev lag luam. Ua los ntawm cov hlau forged zoo, nws muaj lub zog siab thiab tsim nyog rau qhov kub siab, siab siab thiab qhib thiab kaw ntau zaus. Nws feem ntau pom muaj nyob rau hauv kev sib dhos ntawm cov valve pob, cov valve ntiaj teb thiab cov valve tswj hauv kev lag luam xws li roj av, roj av, kev tsim kho tshuaj lom neeg thiab chaw tsim hluav taws xob.

Cov Khoom Siv thiab Cov Qauv Siv

- Khoom siv: Cov hlau forged zoo, Cov hlau tsis xeb austenitic tshwj xeeb xws li 316 304 stainless hlau, 304L / 316Ti thiab 2205 duplex tuaj yeem siv, lossis kho raws li cov neeg siv khoom xav tau.

- Xwm txheej: Kub forging + normalizing (muaj raws li xav tau)

Tus qauv ua tiav: ASTM A105 / ASME B16.34 / EN 10222-2

Cov Qauv Txheej Txheem

Lub cev tseem ceeb yog ib qho khoom siv forging ruaj khov, tsim los ntawm kev tig ntxhib thiab tig zoo

Lub qhov nruab nrab ntawm lub qhov thiab lub qhov ncauj nres raug ua tiav raws li daim duab kos. Lub qhov hla feem ntau muaj lub chamfer lossis R Angle

Nws muaj cov qauv flange ntawm ob qho kawg, nrog rau ib qho kawg feem ntau machined nrog cov qhov threaded lossis cov qhov countersunk rau kev teeb tsa bolts

- Hom flange: RF (Ntsej Muag) lossis MFM (Txiv Neej-Poj Niam)

Kev Ua Haujlwm thiab Kev Ntsuas Qhov Tseeb

Qhov loj me tseem ceeb (xws li cov qhov sab hauv thiab cov qhov ncauj nres) raug tswj hwm raws li qhov kam rau ntawm cov duab kos, feem ntau H7 / h7 lossis raws li cov neeg siv khoom xav tau

- Coaxiality ≤ 0.03mm, kawg lub ntsej muag perpendicularity ≤ 0.05mm (kho raws li cov kab sib txawv)

Qhov kev faib tawm ntawm cov qhov threaded yog npaj raws li qhia hauv daim duab, thiab cov qauv xov txhawb nqa UNC, UNF, M, thiab lwm yam

Qhov roughness ntawm flange nto feem ntau yog tswj tau hauv Ra 3.2 txog 6.3 µm

Qhov Loj Ib Txwm Muaj & Kev Lag Luam Siv

Qhov Loj Ib Txwm Muaj

- Sab nraud txoj kab uas hla: 90-300 hli

- Qhov siab/ntev: 60-200 hli

- Los ntawm qhov txoj kab uas hla: 20-100 hli

- Tus naj npawb ntawm qhov: 4-12

- Qib ua haujlwm siab: Chav kawm 150-2500

Kev Lag Luam Daim Ntawv Thov

Cov chaw tsim roj thiab roj av

Cov kav dej xa khoom siv tshuaj lom neeg

Lub kaw lus tswj hwm pa kub siab

Lub zog hluav taws xob thermal, hydropower thiab nuclear piping systems

Cov Lus Qhia Txog Kev Sib Koom Tes thiab Cov Kev Pabcuam Xaiv Tau

Cov Lus Qhia Txog Kev Sib Koom Tes Hauv Kev Teeb Tsa

Nws raug pom zoo kom siv cov gaskets txheem (xws li cov hlau gaskets) kom ntseeg tau tias qhov kev ua haujlwm sealing ntawm flange

Cov bolts fastening yuav tsum tau ua ntej nruj kom sib npaug hauv kab pheeb ces kaum kom tsis txhob muaj kev nyuaj siab tsis sib npaug

Ua ntej kev teeb tsa, nws yuav tsum tau lees paub tias tsis muaj cov khoom txawv teb chaws lossis burrs hauv cov qhov mating kom tsis txhob cuam tshuam rau qhov chaw.

Cov Kev Pabcuam Xaiv Tau

Tus lej ntawm lub cub tawg thiab daim ntawv pov thawj khoom siv (EN 10204 3.1) tuaj yeem muab ntxiv rau.

Cov qauv tsis yog tus qauv thiab cov kev cai ua tiav tuaj yeem hloov kho raws li cov neeg siv khoom kos duab

Qhov saum npoo tuaj yeem raug txheej nrog cov txheej tiv thaiv xeb raws li qhov xav tau (xws li zinc-based phosphating).
