Cryogenic rooj vag li qubyog cov khoom siv valve tshwj xeeb tsim los tswj cov dej ntws hauv qhov qis - qhov kub thiab txias (feem ntau ua haujlwm ntawm qhov kub thiab txias hauv qab -40℃, thiab txawm mus txog -196℃thiab hauv qab). Lawv lub luag haujlwm tseem ceeb yog qhib lossis kaw cov raj xa dej los ntawm kev nce thiab txo lub rooj vag, tab sis lawv tsis tuaj yeem tswj hwm tus nqi ntws.

Cryogenic Gate Valve Structure thiab Txoj Cai Ua Haujlwm
Qhib thiab kaw cov khoom tsim
Lub rooj vag ntawm lub rooj vag cryogenic txav txav mus rau perpendicular mus rau cov dej kev taw qhia. Lub rooj vag txav tawm (nce qia rooj vag valve) lossis tig (tsis yog- nce qia rooj vag valve) ntawm lub qia valve. Lub rooj vag feem ntau siv ib lub voj voog - zoo li tus los yog sib npaug ob npaug - sealing - cov qauv saum npoo:
Lub Rooj Sib Tham Ntug: Cov chaw sib khi ua ib lub kaum sab xis (feem ntau yog 50 degree, tejzaum nws hloov mus rau 2℃52′ hauv cov xwm txheej cryogenic). Nws tuaj yeem muab faib ua ib qho - rooj vag, ob - rooj vag, thiab cov rooj vag resilient (paub rau kev ua haujlwm sib txawv los ntawm me ntsis deformation).
Parallel Gate: Lub sealing nto yog sib npaug. Nws tau muab faib ua ib qho - rooj vag thiab ob - rooj vag qauv, haum rau cov ntawv thov uas xav tau kev sib khi ua haujlwm siab heev.
Sealing Mechanism
Tus kheej-Kev sib khi: Lub siab nruab nrab ntawm lub hauv paus yog nias lub rooj vag tawm tsam lub rooj zaum valve kom ua tiav lub foob. Haum rau kev siv siab dua.
Forced Sealing: Sab nraud quab yuam (xws li lub tes log lossis lub tshuab hluav taws xob) nias lub rooj vag nruj nreem rau lub rooj zaum ntawm lub rooj, kom ntseeg tau tias kev sib khi ruaj khov ntawm qhov kub thiab txias.
Cryogenic Gate Valve Kev Ua Haujlwm Zoo:
Tsawg kub ua hauj
Nws tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig mus rau -196℃(kua nitrogen kub) lossis qis dua. Cov ntaub ntawv tau txais kev kho mob cryogenic thiab kev sim cuam tshuam los tiv thaiv brittleness.
Sealing Performance
Lub sealing nto tsis yooj yim deformed ntawm qhov kub thiab txias. Ua ke nrog lub rooj vag hloov tau yooj yim tsim, nws zoo tiv thaiv cov xov xwm tawm thiab ua kom muaj kev nyab xeeb.
Tsis tshua muaj dej tsis kam
Cov channel tsis muaj kev cuam tshuam kiag li thaum lub qhov rooj qhib tag nrho, ua rau cov xov xwm tsis tshua muaj dej ntws tawm, haum rau siab - ntws - tus nqi thauj.
Compact Structure thiab Automation
Optimized rau qis- qhov kub thiab txias ua haujlwm, nws yog qhov me me thiab hnyav, yooj yim rau nruab; nws txhawb kev tswj chaw taws teeb thiab tsis siv neeg hloov kho, yoog raws cov kev xav tau ntse.
Cryogenic Gate Valve Daim ntawv thov
Liquefied Natural Gas (LNG) Kev Lag Luam Chain
Tau txais Terminals: Siv rau kev txais, khaws cia, thiab thauj LNG, tiv taus qhov kub tsis tshua muaj siab thiab tswj xyuas qhov chaw kaw kom tsis txhob muaj kev sib tsoo thiab kev nyab xeeb.
Cia Tank thiab Tank Trucks: Tswj kev thauj khoom thiab tshem tawm ntawm cov xov xwm cryogenic kom muaj kev nyab xeeb kev thauj mus los.
Cov cuab yeej sib cais cua
Thaum sib cais cov khoom xws li nitrogen thiab oxygen los ntawm huab cua, cryogenic gate li qub tswj cov dej ntws ntawm cov kua roj kom ntseeg tau tias cov khoom siv ruaj khov.
Txias Cia thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb
Tswj cov refrigerant ntws hauv cov khoom noj txias cia kom tswj tau qhov kub thiab txias; siv nyob rau hauv kev tshawb fawb tshawb fawb rau qis -kub ib puag ncig tswj hauv kev sim lub cev thiab tshuaj lom neeg.
Petrochemical Tail Gas Sib cais
Ua cov roj av cryogenic xws li ethylene thiab liquefied petroleum gases, ua tiav kev sib cais thiab rov qab zoo.
Cryogenic Gate Valve Kev Kho thiab Kev Kho
Kev tshuaj xyuas tsis tu ncua
Txhua hli xyuas lub rooj vag foob nto rau hnav; ua ib qho kev sim siab txhua xyoo.
Tshawb xyuas lub hauv paus foob kom muaj kev ncaj ncees; hloov tam sim ntawd yog tias pom muaj cov leaks.
Lubrication Maintenance
Lubricate lub valve qia thiab kis tau tus mob peb lub hlis twg siv cov roj qis qis (xws li molybdenum disulfide).
Tsis txhob siv cov roj zoo tib yam, vim nws tuaj yeem ua kom khov ntawm qhov kub thiab txias, ua rau muaj teeb meem kev ua haujlwm.
Kev tiv thaiv khov
Nyob rau hauv qhov tsis tshua muaj siab - qhov kub thiab txias, insulate lub valve npog lub caj dab thiab lub tshuab ua haujlwm.
Tsis tu ncua xyuas cov txheej rwb thaiv tsev rau kev ncaj ncees; kho tam sim yog puas.
Anti-Kev Tsim Kho Tsis Zoo
Siv lub tshuab ntsuas phoo (xws li polygonal nrhiav thaiv) txhawm rau tiv thaiv cov neeg ua haujlwm tsis raug cai los ntawm kev qhib lub valve.
Tig lub valve rov qab 1/2 mus rau 1 tig los ntawm qhov qhib tag nrho kom tiv thaiv kev xauv vim qhov kub hloov pauv.
