Xws li cov tseem ceeb tswj cov khoom siv hauv cov raj hluav taws xob, kev xaiv scientific ntawm kev lag luam tsis cuam tshuam nrog kev nyab xeeb ncaj qha. Kab lus no muab kev ntsuas kom tob tob thiab qhov ntsuas kev ua tau zoo thiab cov ntsuas kev ua tau zoo rau cov li qub, muab cov khoom sivKev siv hluav taws xob valverau kev lag luam.
1. Ua haum haum hluav taws xob kev faib tawm
1.1 Nruab Nrab Cutoff Li
● Kev txhais lus: Kev ua txujci davhlau ya nyob twg uas tswj tau rau / tawm Flow ntawm nruab nrab hauv Pipelines.
● Tus tswv cuab raug: Kev sib txuas rooj vag li qub, conical kaw-offves, pob-hom plug li qub.
● Daim Ntawv Qhia Txog: Lub raj xa hluav taws xob txiav tawm rau cov neeg tua cov roj, kev tswj hwm kev cais hauv cov txheej txheem tshuaj lom neeg.
1.2 Nruab Nrab Backflow Kev Tiv Thaiv Cov Khoom Siv
Qaum Technology: Ib-txoj kev qhib thiab kaw cov qauv siv tshuab.
Hom NTAU HOM TSHWJ XEEB: VIAV TXAWJ Kos Li Qub, nqa xyuas li qub.
● Cov ntawv thov raug: Saifflow tiv thaiv rau centrifugal twj tso kua mis.
1.3 Cov Cuab Yeej Haum Ntsig Siab
● Cov Qauv Kev Nyab Xeeb: Ua raws li ASME / GB / T yuav tsum muaj cov cai.
● Cov tsis muaj nqis: teeb tsa lub siab, ua kom lub siab sib txawv, kev tawm tsam me me.
● Cov kev cai tsim kho: Cov qauv kev teeb tsa rau cov khoom siv boiler siab-cov kabmob khoom siv.
2. Lub siab ntsuas cov ntawv pov thawj
2.1 Lub tshuab nqus tsev-qib li qub: kev ua haujlwm siab siab sib txawv <101.35 kpa.
2.2 Cov pa siab siab ntau yam:
● Cov li ntawd qis qis: PN tsawg dua lossis sib luag rau 16 bar (chav kawm 150).
● Nruab nrab-siab li qub: PN 25-64 bar (chav {2}}).
● Kev siv lub siab siab: PN 100-800 bar (chav {2}}).
● Ulva-kev kub siab tshwj xeeb li qub: Pn ntau dua lossis sib npaug nrog 1000 bar (nuclear fais fab thawj lub voj system).
3. Cov ntsuas kub txav hluav taws xob
3.1 Cryogenic-qib li qub (-269 degree rau -100 degree):
● Cov khoom siv uas yuav tsum tau: Tshwj Xeeb Kev Kho Mob ntawm Antenitic Stainless.
3.2 Tsawg-kub li qub (-100 degree rau -40 degree):
● SEATING thev naus laus zis: Dual Elastic Sealing qauv.
3.3 Cov Khoom Siv Hluav Taws Xob Ntau Li Qub (-40 degree rau 120 degree):
● Cov ntaub ntawv nquag siv: WCB Carbon Steel / CF8 Stainless hlau.
3.4 High-temperature Special Valves (>450 degree):
● Kev teeb tsa tshwj xeeb: Tshav kub Dissipation Valve / Chromium-Molybdenum steel steel valve lub cev.
Los ntawm kev faib tawm kub yog qhov yooj yim,Kev siv hluav taws xob valveMuaj peev xwm npog tag nrho cov kev xav tau, los ntawm kua hydrogen cia thiab tsheb thauj mus los molten cov ntsev system.
4. Kev faib tawm los ntawm Txoj Cai Ua Raws Cai
4.1 Automal Automal: Cov li qub ua haujlwm tsis muaj zog sab nraud, cia siab rau lub zog ntawm nruab nrab nws tus kheej. Piv txwv suav nrog li qub, nyem li qub, cov roj li qub, xyuas li qub, thiab tus kheej tswj cov li qub. Cov ntawv no cov koog theem pib ntawm cov ntseKev siv hluav taws xob valve.
4.2 fais li qub: hluav taws xob hluav taws xob tuaj yeem tsav los ntawm ntau lub zog. Lawv suav nrog:
● Hluav taws xob cov li qub: powered los ntawm hluav taws xob.
● Pneumatic li qub: tsav los ntawm compressed cua.
● Cov kav hydraulic: tsav los ntawm kua siab xws li roj. Ib qho ntxiv, muaj kev sib xyaw ua ke ntawm cov hom saum toj no, xws li pneumatic-fais qub.
4.3 Kev tuav cov li qub: kev tuav tes yog kev ua haujlwm siv Handwheels, tuav, levers, lossis sprockets. Thaum lub valve qhib thiab kaw lub zog loj yog loj, lub iav lossis cov roj teeb iav tuaj yeem ntxiv ntawm cov tes thiab cov qia valve. Rau tej thaj chaw ua haujlwm tej thaj chaw deb, cov pob qij txha thoob ntiaj teb thiab cov ntaub ntawv tiv thaiv no kuj tseem siv tau yog tias tsim nyog.
Cov lus qhia no muab lub moj khaum rau kev txhim tsa lub valve cov khoom lag luam tsim, pab cov neeg siv hauv kev tsimKev siv hluav taws xob valveUas tau ntsib ASME B16.34 / GB / T 12224 cov qauv thiab kev muab cov kev daws teeb meem rau kev ua haujlwm sib txawv.
