Raws li cov khoom tseem ceeb tau siv dav hauv cov tshuab tswj dej, lub pob valve ua lub luag haujlwm tseem ceeb hauv kev lag luam, pej xeem, thiab kev siv tshwj xeeb ua tsaug rau lawv cov qauv tsim tshwj xeeb thiab kev ua tau zoo heev.Lawv cov yam ntxwv tseem ceeb suav nrog kev ua haujlwm yooj yim, txhim khu kev qha sealing, kua dej sib xws, thiab kev saib xyuas yooj yim, ua rau lawv yog ib qho tseem ceeb valve hom nyob rau hauv niaj hnub piping systems.
Compact Structure thiab ceev qhib thiab kaw
Lub pob valve lub ntsiab lus tseem ceeb yog ib tug kheej kheej nrog ib ncig ntawm - qhov. Kev sib hloov 90-degree tso cai rau tag nrho qhib lossis kaw. Qhov kev tsim no ua rau pob li qub yooj yim heev rau kev khiav lag luam; tsuas yog tig tus kov lossis tus actuator hloov txoj hauv kev ntws hauv ib feem ntawm ib pliag. Muab piv rau lub rooj vag lossis lub ntiaj teb li qub, pob li qub muaj qhov qhib thiab kaw tau zoo dua, ua rau lawv tshwj xeeb tshaj yog tsim nyog rau cov ntawv thov kom kaw nrawm lossis tswj cov kua dej, xws li kev kaw thaum muaj xwm txheej ceev lossis cov txheej txheem tswj tsis siv neeg.
Kev ua tau zoo sealing zoo thiab tsis tshua muaj kev pheej hmoo
Pob li qub feem ntau siv cov ntsaws ruaj ruaj (xws li polytetrafluoroethylene (PTFE)) lossis hlau ntsaws ruaj ruaj (xws li cov hlau tsis muaj steel lossis hlau alloy) kom tiv taus qhov kub thiab txias. Thaum lub pob tig mus rau qhov chaw kaw, qhov dhau los ntawm - lub qhov yog perpendicular mus rau cov yeeb nkab axis, thiab lub pob saum npoo nruj nreem kaw nrog lub rooj zaum valve, tsim ib qho xoom - leakage los yog tsawg heev - leakage foob. Cov yam ntxwv no ua rau pob li qub tshwj xeeb rau cov ntawv thov uas yuav tsum muaj kev tswj xyuas kom nruj, xws li kev xa cov roj, cov txheej txheem tshuaj, lossis lub tshuab nqus tsev.
Tsis tshua muaj dej tsis kam, dav siv ntau yam
Txoj hauv kev ntws sab hauv ntawm lub pob valve feem ntau yog ncaj nraim - dhau los lossis tag nrho - bore tsim, tso cai rau cov kua dej ntws tsis zoo, ua rau muaj kev poob qis dua li lwm hom valve (xws li lub ntiaj teb li qub). Qhov kev ua haujlwm qis qis no tsis yog tsuas yog txhim kho lub zog ua haujlwm tab sis kuj txo qis hnav thiab corrosion los ntawm siab - nrawm nrawm. Tsis tas li ntawd, pob li qub tuaj yeem ua kom haum rau ntau yam kua dej, suav nrog dej, roj, roj, slurries, thiab txawm tias qee cov tshuaj corrosive. Cov khoom siv thiab cov foob pob ua ke tuaj yeem xaiv tau yooj yim kom haum rau kev ua haujlwm tshwj xeeb.
High durability thiab tsis tshua muaj txij nkawm
Pob li qub muaj qhov txav tsawg dua (tsuas yog lub pob sib cuag lub rooj zaum), thiab qhov chaw sib khi tsis tshua muaj kev cuam tshuam rau kev yaig lossis xeb, ua rau lub neej ua haujlwm ntev. Raws li kev ua haujlwm ib txwm muaj, pob li qub yuav tsum tau saib xyuas tsawg kawg nkaus, tsuas yog yuav tsum tau kuaj xyuas lub sijhawm ntawm lub foob thiab lubrication ntawm lub tshuab ua haujlwm. Rau lub sijhawm ntev -cov kav dej kav ntev (xws li cov kav dej thiab roj lossis cov kav dej hauv tsev), qhov kev saib xyuas qis ntawm cov pob li qub txo qis cov nqi khiav haujlwm.
Ntau yam sib txawv raws li cov kev xav tau tshwj xeeb
Ntxiv nrog rau cov qauv pob li qub, cov qauv tsim qauv xws li V- zoo li lub pob li qub (rau cov kev cai siab raug), peb - txoj kev pob li qub (rau kev khiav dej num / kev sib txuas tswj), thiab cov pob li qub cryogenic (tsim rau ib puag ncig hauv qab -196 degree) ntxiv nthuav lawv daim ntawv thov scenarios. Cov kev hloov pauv no, los ntawm cov qauv tsim kho lossis cov khoom siv, muab kev hloov pauv ntau dua hauv cov ntawv thov tshwj xeeb, xws li cov tshuaj zoo, cryogenic engineering, lossis cov khoom noj thiab tshuaj lag luam.
Xaus
Hauv cov ntsiab lus, pob li qub, nrog rau lawv qhov ceev ceev qhib thiab kaw, txhim khu kev qha sealing, tsis tshua muaj dej tsis kam, thiab kev hloov pauv dav, tau dhau los ua qhov kev xaiv tseem ceeb hauv kev lag luam tswj dej. Txawm hais tias nyob rau hauv niaj hnub los yog hnyav ib puag ncig, pob li qub muab kev daws teeb meem zoo thiab ruaj khov. Lawv cov txiaj ntsig zoo thiab tus nqi -kev ua tau zoo ua kom lawv qhov tseem ceeb txuas ntxiv hauv kev txhim kho kev lag luam yav tom ntej.
