Tsis ntev los no, Lub Koom Haum rau Kev Sib Koom Tes Kev Lag Luam thiab Kev Txhim Kho (OECD) tau tshaj tawm nws cov ntaub ntawv tshaj tawm txog kev lag luam nruab nrab ntawm lub sijhawm. Daim ntawv tshaj tawm cia siab tias kev loj hlob thoob ntiaj teb GDP yuav yog 5.8% hauv 2021, piv nrog kev kwv yees ua ntej ntawm 5.6%. Daim ntawv tshaj tawm kuj tau kwv yees tias ntawm G20 cov tswv cuab kev lag luam, Tuam Tshoj txoj kev lag luam yuav loj hlob los ntawm 8.5% hauv 2021 (piv rau kev kwv yees ntawm 7.8% hauv lub Peb Hlis xyoo no). Kev loj hlob tsis tu ncua thiab ruaj khov ntawm kev lag luam thoob ntiaj teb kev sib sau ua ke tau tsav txoj kev loj hlob ntawm downstream valve industries xws li roj thiab natural gas, hluav taws xob fais fab, dej kho, tshuaj lom neeg kev lag luam, thiab kev tsim kho hauv nroog, uas ua rau kev loj hlob sai ntawm kev lag luam valve thiab kev lag luam tseem ceeb. .
A. Txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam valve
Los ntawm kev sib koom ua ke thiab kev ywj pheej ntawm kev tsim khoom lag luam thiab ntau tog neeg, kuv lub teb chaws cov khoom siv valve tsim kev lag luam tau nyob rau hauv xyoo tas los no hauv nuclear fais fab nroj tsuag nuclear-qib li qub, tag nrho cov welded loj-ntev pob li qub rau cov kav dej ntev ntev, tseem ceeb li qub rau ultra-supercritical thermal fais fab units, petrochemical teb, thiab chaw nres tsheb fais fab kev lag luam. Qee cov khoom lag luam siab kawg valve nyob rau hauv kev ua haujlwm tshwj xeeb tau ua tiav kev vam meej, thiab qee qhov tau ua tiav hauv cheeb tsam, uas tsis tsuas yog hloov cov khoom lag luam, tab sis kuj cuam tshuam txawv teb chaws monopoly, tsav kev hloov pauv kev lag luam thiab kev txhim kho thiab kev tshawb fawb thiab thev naus laus zis.
B. Kev sib tw qauv ntawm Tuam Tshoj txoj kev lag luam valve
Tuam Tshoj txoj kev lag luam valve muaj zog tsis muaj zog rau kev lag luam cov khoom siv raw khoom, ntau cov khoom siv hauv tsev qis kawg yog nyob rau theem ntawm kev sib tw nqi (wafer npauj npaim valve,lug npauj npaim valve, flanged npauj npaim valve,rooj vag valve,kos valve, thiab lwm yam) Thiab lub zog sib cog lus rau kev lag luam qis qis kuj yog me ntsis tsis txaus; nrog kev nkag mus rau cov peev txawv teb chaws tsis tu ncua, nws cov hom lag luam thiab thev naus laus zis Kev nkag mus ntawm cov peev txheej txawv teb chaws yuav coj kev hem thawj loj thiab kev ntxhov siab rau cov lag luam hauv tsev; Tsis tas li ntawd, li qub yog ib yam ntawm cov tshuab dav dav, thiab cov khoom siv tshuab dav dav yog cov yam ntxwv ntawm kev muaj zog ntau yam, cov qauv yooj yim thiab kev ua haujlwm yooj yim, uas tseem ua rau kev tsim khoom yooj yim Imitation yuav ua rau qis qis dua kev tsim kho thiab kev sib tw tsis zoo hauv kev ua lag luam, thiab muaj qee yam kev hem thawj ntawm kev hloov pauv.
C. Kev lag luam yav tom ntej rau li qub
Tswj li qub (regulating li qub) muaj kev cia siab rau kev loj hlob. Lub valve tswj, tseem hu ua lub regulating valve, yog ib tug tswj tivthaiv nyob rau hauv cov kua conveying system. Nws muaj kev ua haujlwm xws li kev txiav tawm, kev tswj hwm, kev hloov pauv, kev tiv thaiv kev rov qab, kev tiv thaiv hluav taws xob, kev hloov pauv lossis kev cuam tshuam dhau los. Nws yog ib qho tseem ceeb ntawm kev tsim khoom ntse. Cov teb muaj xws li roj av, petrochemical, tshuaj, papermaking, kev tiv thaiv ib puag ncig, lub zog, hluav taws xob, mining, metallurgy, tshuaj, zaub mov thiab lwm yam lag luam.
Raws li ARC's "Tuam Tshoj Tswj Valve Kev Tshawb Fawb Kev Tshawb Fawb", qhov kev lag luam tswj kev lag luam hauv tsev yuav tshaj li US $ 2 nphom hauv 2019, nrog kev nce xyoo ntawm ntau dua 5%. Nws cia siab tias qhov kev loj hlob txhua xyoo yuav yog 5.3% hauv peb lub xyoos tom ntej. Lub lag luam tswj valve yog tam sim no dominated los ntawm txawv teb chaws hom. Hauv xyoo 2018, Emerson tau coj lub siab-kawg tswj valve nrog kev lag luam feem ntawm 8.3%. Nrog rau kev nrawm ntawm kev hloov pauv hauv tsev thiab kev txhim kho kev tsim khoom ntse, cov tuam txhab tswj hwm hauv tsev muaj kev loj hlob zoo.
Kev hloov hauv tsev ntawm hydraulic li qub yog nrawm. Hydraulic qhov chaw yog dav siv nyob rau hauv ntau hom kev taug kev machinery, industrial machinery thiab cov khoom loj. Cov kev lag luam hauv qab no suav nrog kev siv tshuab, tsheb, metallurgical machinery, tshuab cuab yeej, mining machinery, agricultural machinery, ships, thiab roj av machinery. Hydraulic li qub yog cov tseem ceeb hydraulic Cheebtsam. Hauv xyoo 2019, hydraulic li qub suav txog 12.4% ntawm tag nrho cov khoom tsim tawm ntawm Tuam Tshoj cov khoom siv hydraulic (Hydraulic Pneumatic Seals Industry Association), nrog rau kev lag luam loj txog li 10 billion yuan. Tam sim no, kuv lub teb chaws high-end hydraulic li qub cia siab rau kev ntshuam (hauv xyoo 2020, kuv lub teb chaws hydraulic kis valve xa tawm yog 847 lab yuan, thiab kev xa tawm tau siab txog 9.049 billion yuan). Nrog rau kev nrawm ntawm kev hloov pauv hauv tsev, kuv lub teb chaws hydraulic valve kev lag luam tau loj hlob sai.
