Kutshanje, uMbutho weNtsebenziswano kwezoQoqosho noPhuhliso (OECD) ukhuphe ingxelo yawo yamva nje yenkangeleko yezoqoqosho yaphakathi kwixesha eliphakathi. Ingxelo ilindele ukukhula kwe-GDP yehlabathi kube yi-5.8% ngo-2021, xa kuthelekiswa noqikelelo lwangaphambili lwe-5.6%. Le ngxelo ikwaqikelela ukuba phakathi koqoqosho olungamalungu e-G20, uqoqosho lwase-China luya kukhula nge-8.5% ngowama-2021 (xa kuthelekiswa noqikelelo lwe-7.8% ngoMatshi walo nyaka). Ukukhula okuzinzileyo koqoqosho lwehlabathi jikelele kuqhubele phambili uphuhliso lwamashishini evalvu esezantsi njenge-oyile kunye negesi yendalo, amandla ombane, unyango lwamanzi, ishishini lemichiza kunye nolwakhiwo lwasezidolophini, okukhokelela kuphuhliso olukhawulezayo lweshishini levalvu kunye nomsebenzi obalulekileyo wentengiso. .
A. Ubume bophuhliso loshishino lwevalvu yaseTshayina
Ngokusebenzisa iinzame ezidibeneyo kunye nokuveliswa okuzimeleyo kwamashishini okuvelisa kunye namaqela ahlukeneyo, ushishino lwelizwe lam lokuvelisa izixhobo zevalvu sele kwiminyaka yakutshanje kwisixhobo samandla enyukliya kwiivalvu zomgangatho wenyukliya, zonke ezi-welded iivalvu zebhola ezinobubanzi obukhulu kumgama omde wemibhobho yegesi yendalo, iivalvu ezingundoqo kwiiyunithi amandla thermal ultra-supercritical, amasimi petrochemical, kunye namashishini isikhululo samandla. Ezinye iimveliso zevalve ezikumgangatho ophezulu phantsi kweemeko ezikhethekileyo zokusebenza ziye zenza inkqubela phambili, kwaye ezinye ziye zafumana indawo yokuhlala, engazange ithathe indawo yokuthengisa ngaphandle, kodwa iphinde yaphule i-monopoly yangaphandle, ukuqhuba ukuguqulwa kweshishini kunye nokuphucula kunye nesayensi kunye neteknoloji.
B. Ipateni yokhuphiswano lweshishini levalvu yaseTshayina
Ishishini lokuvelisa ivalvu yaseTshayina linamandla okuxoxisana abuthathaka kushishino lwemathiriyeli ekrwada enyukayo, inani elikhulu leemveliso zasekhaya ezikumgangatho ophantsi zikwinqanaba lokhuphiswano lwamaxabiso (ivelufa yebhabhathane,lug butterfly valve, ivalve yebhabhathane eneflanged,ivalve yesango,khangela ivalvenjl. ngokungena rhoqo kwenkunzi yamazwe angaphandle, uphawu lwayo kunye nemiba yobuchwepheshe Ukungena kwenkunzi yangaphandle kuya kuzisa izoyikiso ezinkulu kunye noxinzelelo kumashishini angaphakathi; ukongeza, iivalvu luhlobo koomatshini ngokubanzi, kunye neemveliso koomatshini ngokubanzi ziphawulwa ngokuguquguquka olomeleleyo, ulwakhiwo olulula kunye nokusebenza ngokulula, nto leyo ekhokelela ekubeni kube lula ukwenza ukulinganisa kuya kubangela ulwakhiwo oluphinda-phindayo olukumgangatho ophantsi kunye nokhuphiswano olungalungelelananga kwimarike, kwaye kukho isoyikiso esithile sokuthatha indawo.
C. Amathuba emarike exesha elizayo kwizivalo
Iivalvu zokulawula (iivalvu ezilawulayo) zinethuba elibanzi lokukhula. Ivalve yokulawula, eyaziwa ngokuba yivalve elawulayo, licandelo lolawulo kwinkqubo yokuhambisa ulwelo. Inemisebenzi efana nokunqunyulwa, ukulawulwa, ukuphambukisa, ukuthintela ukubuya umva, ukuzinzisa kombane, ukuphambuka okanye ukunyibilika koxinzelelo loxinzelelo. Lelinye lamacandelo aphambili kwimveliso ekrelekrele. Amasimi abandakanya i-petroleum, i-petrochemical, ikhemikhali, i-papermaking, ukukhuselwa kwendalo, amandla, amandla ombane, imigodi, i-metallurgy, amayeza, ukutya kunye namanye amashishini.
Ngokwe-ARC's "Ingxelo yoPhando lweMarike yeValve yaseTshayina", imarike yevalve yolawulo lwasekhaya iya kudlula i-US $ 2 yebhiliyoni ngo-2019, ngokunyuka konyaka-ngonyaka ngaphezulu kwe-5%. Kulindeleke ukuba iqondo lokukhula elihlanganisiweyo lonyaka libe yi-5.3% kule minyaka mithathu izayo. Imarike yevalvu yolawulo okwangoku ilawulwa ziimpawu zangaphandle. Kwi-2018, u-Emerson uholele i-valve yokulawula isiphelo esiphezulu kunye nesabelo semarike ye-8.3%. Ngokukhawulezisa ukutshintshwa kwekhaya kunye nophuhliso lwemveliso ekrelekrele, abavelisi bevalvu yolawulo lwasekhaya banamathuba amahle okukhula.
Ukutshintshwa kwasekhaya kweevalvu zehydraulic kuyakhawuleza. Iinxalenye zeHydraulic zisetyenziswa ngokubanzi kwiintlobo ezahlukeneyo zoomatshini bokuhamba, oomatshini boshishino kunye nezixhobo ezinkulu. Amashishini asezantsi abandakanya oomatshini bokwakha, iimoto, oomatshini besinyithi, izixhobo zoomatshini, oomatshini bemigodi, oomatshini bezolimo, iinqanawa, kunye noomatshini bepetroleum. Iivalvu zeHydraulic zezona zinto zingundoqo zehydraulic. Ngo-2019, iivalvu zehydraulic zibalelwa kwi-12.4% yexabiso lilonke lemveliso ye-hydraulic core components yaseTshayina (iHydraulic Pneumatic Seals Industry Association), enobungakanani bemarike obumalunga ne-10 yeebhiliyoni zeeyuan. Okwangoku, iivalvu zehydraulic zelizwe lam ezikumgangatho ophezulu zixhomekeke ekuthengisweni kumazwe angaphandle (ngowama-2020, ukuthunyelwa kwevalvu ye-hydraulic transmission yelizwe lam ibizizigidi ezingama-847 zeeyuan, kwaye ukungenisa elizweni bekuphezulu kangange 9.049 yeebhiliyoni zeeyuan). Ngokukhawuleziswa kokutshintshwa kwasekhaya, imakethi yelizwe lam ye-hydraulic valve ikhule ngokukhawuleza.
