Case Study: Daim ntawv thov piv txwv ntawm American Standard Cast Steel Globe Valves nyob rau hauv qhov kub thiab txias ib puag ncig

"Case Study: Daim Ntawv Thov Piv txwv ntawm American Standard Cast Steel Globe Valves nyob rau hauv qhov kub thiab txias ib puag ncig"

American standard cam khwb cia steel ntiaj teb li qub feem ntau ntsib qhov kub thiab txias siab nyob rau hauv cov ntaub ntawv siv, uas tso rau pem hauv ntej siab yuav tsum tau rau cov khoom, qauv, thiab kev ua tau zoo ntawm lub valve. Tsab ntawv xov xwm no yuav tshawb txog daim ntawv thov ntawm American standard cam khwb cia steel ntiaj teb li qub nyob rau hauv high-temperature thiab high-pressure ib puag ncig los ntawm ib tug tshwj xeeb cov ntaub ntawv, thiab soj ntsuam cov tseem ceeb ntawm lawv tsim thiab daim ntawv thov txheej txheem.

Case keeb kwm:

Nyob rau hauv lub refining chav tsev ntawm ib tug petrochemical enterprise, ib tug American standard cam khwb cia steel ntiaj teb valve yuav tsum tau los tswj cov ndlwg ntawm hydrocarbon media nyob rau hauv kub thiab siab. Qhov kub nyob rau hauv qhov kev ua haujlwm no yog li 400 ° C thiab lub siab nce mus txog 150MPa. Vim lub siab corrosiveness thiab flammability ntawm qhov nruab nrab, tshwj xeeb yuav tsum tau muab tso rau ntawm kev xaiv ntawm li qub.

1, Tsim cov ntsiab lus

1. Kev xaiv cov khoom siv: Xav txog cov yam ntxwv ntawm qhov kub thiab txias, siab siab, thiab corrosive media, American standard cam khwb cia steel ntiaj teb valve ua los ntawm cov khoom siv hlau alloy tau xaiv. Cov khoom siv no tuaj yeem tswj xyuas cov khoom zoo ntawm qhov kub thiab txias thiab muaj kev tiv thaiv siab rau cov xov xwm corrosive.
2. Tus qauv tsim: Txhawm rau tiv thaiv kev kub siab, lub valve tau txais lub plhaub ntxiv thiab disc tsim los xyuas kom meej cov txheej txheem ntawm lub valve nyob rau hauv siab. Nyob rau tib lub sijhawm, ob chav sealing qauv yog saws kom ua tiav lub hom phiaj ntawm xoom to.
3. Kev ntsuas kub siab: Hauv qhov chaw kub kub, kev ua haujlwm ntawm cov khoom siv valve thiab cov ntsaws ruaj ruaj yuav raug cuam tshuam. Yog li ntawd, nyob rau hauv tus txheej txheem tsim, nws yog tsim nyog los xav txog lub thermal expansion coefficient ntawm cov khoom thiab cov durability ntawm lub foob nyob rau hauv high kub.
4. Kev kuaj thiab ntawv pov thawj: Txhawm rau kom ntseeg tau tias lub valve tuaj yeem ua haujlwm nyab xeeb raws li kev ua haujlwm tiag tiag, kev ntsuas nruj nruj thiab kev ntsuas cov khoom siv tau ua tiav, thiab tau txais cov ntawv pov thawj kev nyab xeeb cuam tshuam.

2, Daim ntawv thov cuam tshuam

1. Kev Nyab Xeeb: Tom qab kev teeb tsa, Asmeskas tus qauv cam khwb cia steel ntiaj teb valve tau ua tiav dhau los ntawm cov chaw tsim khoom thiab kev sim ntawm qhov chaw, ua kom muaj kev nyab xeeb hauv kev kub ntxhov thiab kev kub ntxhov.
2. Kev ntseeg tau: Lub valve tau pom tias muaj kev ruaj ntseg zoo thaum lub sijhawm ua haujlwm, tsis muaj qhov xau lossis lwm yam tsis raug, ua kom cov txheej txheem txuas ntxiv mus.
3. Corrosion tsis kam: Vim yog xaiv cov khoom tsim nyog, lub valve nthuav tawm zoo corrosion kuj thaum ntsib cov xov xwm corrosive, ncua kev pab cuam lub neej ntawm lub valve.

Cov ntsiab lus:

Daim ntawv thov ntawm American standard cam khwb cia steel ntiaj teb li qub nyob rau hauv high-temperature thiab high-pressure ib puag ncig yuav tsum tau muab kev txiav txim siab ntawm ntau yam xws li cov khoom xaiv, cov qauv tsim, kub nce los, thiab xeem ntawv pov thawj. Los ntawm kev kawm txog cov ntaub ntawv no, peb tuaj yeem pom tias dhau los ntawm kev tsim qauv thiab xaiv cov khoom siv, American standard cam khwb cia steel ntiaj teb li qub tuaj yeem muab kev nyab xeeb, txhim khu kev qha, thiab kev daws teeb meem zoo nyob rau hauv kev ua haujlwm hnyav. Qhov no muaj qhov tseem ceeb siv tus nqi rau cov ntawv thov kev lag luam zoo ib yam li qhov kub thiab txias ua haujlwm siab.
