1. LNG Cryogenic Pob Valve - Qhov no yog cov khoom siv dav dav thiab feem ntau siv hauv LNG system.
Cov yam ntxwv zoo
Ntev Neck Bonnet: Los Standard.
Anti-blowout qia: Pab tiv thaiv lub qia kom tsis txhob tawg thaum lub siab nyob hauv.
Dual kaw-off thiab venting muaj nuj nqi: Thaum lub valve raug kaw, lub venting valve pab tso LNG uas yog xauv rau hauv lub valve chamber. Qhov kev txiav txim no tiv thaiv txhua qhov txawv txav siab tshwm sim los ntawm vaporization.
Tshwj xeeb Pob Lub Rooj Tsim: Feem ntau yuav tsum muaj cov hlau rau hlau foob lossis cov foob mos muag nrog kev them nyiaj rau cov khoom siv cryogenic shrinkage.
Daim ntawv thov:
Natural Gas Liquid storage tank Inlet/Outlet
Kev sib txuas ntawm caj npab loading
BOG (Lub raj mis-Off Gas) tuav
Pib thiab nres lub zog regulator skids nrog rau cov vaporizers
Kaw cov txheej txheem dav dav
2. LNG Cryogenic Shut-off Valve - Rau kev siv qhov twg muaj kev tswj xyuas siab lossis kaw - tawm yog xav tau.
Riemann Nto
Lub kaum sab xis lossis Y hom valve lub cev: Tsis tshua muaj dej tsis kam, tawm yooj yim, tsis muaj xov xwm tuav.
Disc-zoo li lub kaus mom: Muaj peev xwm txhawb kev ntxhov siab vim qhov hloov pauv ntawm qhov kub thiab txias.
Bellows Seal: Ib qho ntawm cov khoom tseem ceeb. Lub hauv paus, uas yog welded rau lub valve qia, tsim ib tug metallic sealing barrier los xyuas kom meej tag nrho impossibility ntawm to ntawm lub valve qia packing ntawm tsawg kub, muab lub siab tshaj plaws guarantee rau lub 'zero sab nraud to' muaj nuj nqi.
Kev Siv: Cov kav dej uas xav tau kev tswj xyuas cov kua dej kom raug (cov qauv ntsuas ntsuas, piv txwv)
Toxic daim ntaub ntawv nrog siab sealing xav tau
BOG COMPRESSOR INLET/OUTLET
Cov cuab yeej cua thiab Nitrogen Pipelines
3. Cryogenic Gate Valve-LNG - Hauv loj - nplai LNG kis kab uas yuav tsum muaj tag nrho - bore, tsis muaj zog, thiab tag nrho kaw functionality yog thov.
Cov yam ntxwv nta: Rigid wedge los yog resilient rooj vag: Qhov no yog siv los kho qhov sib txawv ntawm tus nqi ntawm contraction ntawm lub valve lub cev thiab lub rooj vag ntawm qhov kub thiab txias.
Tag nrho bore tsim: Tsawg tsis kam mus ntws, yog li du dhau ntawm cov npua.
Kuj tseem muaj lub caj dab ntev lub kaus mom, tiv thaiv - blowout valve qia.
Cov ntawv thov: Cov kav dej hauv lub cev tuav LNG yuav tsum tau ua haujlwm puv - tho txawv.
Bulk inlet thiab / lossis qhov hluav taws xob piping hauv LNG txais tos cog lossis liquefaction cog.
4. LNG Cryogenic Safety Valve/Relief Valve - Ib qho tseem ceeb heev rau kev nyab xeeb kev nyab xeeb kev tiv thaiv cov khoom siv thiab cov kav dej los ntawm kev puas tsuaj ntau dhau.
Cov yam ntxwv ntawm tus qauv: Feem ntau tsim rau cov pa roj-kua ob- theem nruab nrab ntws.
Lub caij nplooj ntoos hlav chamber cais tawm los ntawm cov kua dej cryogenic thiab yog li kev ua haujlwm ntawm cov springs tsis cuam tshuam los ntawm qhov kub thiab txias.
Lub sealing nto thiab lub actuating mechanism yuav tsum tau txhim khu kev qha; lawv yuav tsum qhib tsuas yog ntawm qhov teeb tsa siab thiab kaw ruaj khov thaum rov- zaum.
Daim ntawv thov:
LNG cia tank Cheebtsam (lub ntsiab & seem kev nyab xeeb li qub)
Kev tiv thaiv overpressure ntawm LNG Pipelines thiab Cia Tank
Bog systems
5. LNG Cryogenic Check Valve - Qhov no yuav tiv thaiv cov kua dej rov qab thiab yuav tiv thaiv ntau yam tseem ceeb ntawm LNG
Cov yam ntxwv ntawm tus qauv: Feem ntau pom nyob rau hauv viav vias thiab nqa kev teeb tsa.
Nws lub pob valve yog qhov hnyav, yog li ceev - ua haujlwm thaum tuav cov dej me me.
High - zoo sealing, tsis muaj dej los ntawm sab nraub qaum. Daim ntawv thov: txwv tsis pub rov qab ntawm cov xov xwm thaum lub twj tso kua mis kaw, LNG twj tso kua mis qhov hluav taws xob. Compressor inlet & qhov hluav taws xob. Cov kav dej uas rov qab tuaj yeem ua tau. 6. Lwm Cov Khoom Tshwj Xeeb Cryogenic Npauj Npaim Valves: Rau kev tswj hwm lossis kev sib cais ntawm txoj kab uas hla loj, qhov sib txawv siab sib txawv siv rau qhov cua thiab BOG kab. Needle Valves: Cov no tswj cov nqi me me thiab feem ntau pom muaj nyob rau hauv cov ntsuas ntsuas kab thiab cov kab piv txwv.
