Muva nje, iNhlangano Yezokubambisana Nezokuthuthukiswa Komnotho (i-OECD) ikhiphe umbiko wayo wakamuva wokubukeka komnotho wamaphakathi nonyaka. Umbiko ulindele ukukhula kwe-GDP yomhlaba wonke kube ngu-5.8% ngo-2021, uma kuqhathaniswa nesibikezelo sangaphambilini sama-5.6%. Umbiko uphinde ubikezele ukuthi phakathi kwezomnotho ezingamalungu e-G20, umnotho waseShayina uzokhula ngama-8.5% ngo-2021 (uma kuqhathaniswa nesibikezelo sama-7.8% ngoNdasa walo nyaka). Ukukhula okuqhubekayo nokuzinzile kweqoqo lomnotho womhlaba wonke kugqugquzele ukuthuthukiswa kwezimboni zama-valve aphansi njengowoyela negesi yemvelo, amandla kagesi, ukuhlanzwa kwamanzi, imboni yamakhemikhali, nokwakhiwa kwamadolobha, okuholele ekuthuthukisweni okusheshayo kwemboni yama-valve kanye nomsebenzi obalulekile wemakethe. .
A. Isimo sokuthuthuka somkhakha wamavalvu waseChina
Ngemizamo ehlanganyelwe kanye nokuqanjwa okusha okuzimele kwamabhizinisi okukhiqiza kanye nezinhlaka ezehlukene, imboni yokukhiqiza imishini yamavalvu yezwe lami eminyakeni yamuva nje isesikhumulweni sokuphehla amandla enuzi amavalvu ezinga lenuzi, amavalvu amabhola anobubanzi obukhulu ashiselwe amapayipi egesi yemvelo amabanga amade, ama-valve abalulekile amayunithi wamandla ashisayo e-ultra-supercritical, izinkambu ze-petrochemical, nezimboni zeziteshi zikagesi. Eminye imikhiqizo yama-valve asezingeni eliphezulu ngaphansi kwezimo ezikhethekile zokusebenza yenze inqubekelaphambili eyimpumelelo, futhi eminye izuze ukwenziwa kwasendaweni, okungagcini nje ngokuthatha indawo yokungenisa, kodwa futhi yaphula ukubusa kwamanye amazwe, ukushayela uguquko nokuthuthukiswa kwezimboni kanye nenqubekelaphambili yesayensi nezobuchwepheshe.
B. Iphethini yokuncintisana yemboni yamavalvu yaseChina
Imboni yokukhiqiza ama-valve yaseShayina inamandla okuxoxisana abuthakathaka embonini yempahla eluhlaza, inani elikhulu lemikhiqizo yasekhaya esezingeni eliphansi isesigabeni sokuncintisana kwamanani(i-wafer butterfly valve,i-lug butterfly valve, i-valve ye-butterfly ene-flanged,i-valve yesango,hlola i-valve, njll) Futhi amandla okuxoxisana embonini esezansi nomfula nawo awanele kancane; ngokungena okuqhubekayo kwezimali zakwamanye amazwe, uhlobo lwayo kanye nezici zezobuchwepheshe Ukungena kwezimali zakwamanye amazwe kuzoletha izinsongo ezinkulu nezingcindezi kumabhizinisi asekhaya; ngaphezu kwalokho, ama-valve awuhlobo lwemishini evamile, futhi imikhiqizo yemishini ejwayelekile ibonakala ngokuguquguquka okuqinile, isakhiwo esilula kanye nokusebenza okulula, okuholela ekukhiqizeni okulula kokulingisa kuzodala ukwakhiwa okuphindaphindayo okuphansi kanye nokuncintisana okungahlelekile emakethe, futhi kukhona usongo oluthile lokuthatha indawo.
C. Amathuba ezimakethe zesikhathi esizayo zamavalvu
Amavalvu okulawula (amavalvu alawulayo) anamathuba abanzi okukhula. I-valve yokulawula, eyaziwa nangokuthi i-valve elawulayo, iyingxenye yokulawula ohlelweni lokudlulisa uketshezi. Inemisebenzi efana nokunqamula, ukulawula, ukuphambukisa, ukuvimbela ukugeleza emuva, ukuqiniswa kwe-voltage, ukuphambukisa noma ukukhululeka kwengcindezi echichimayo. Ingenye yezingxenye eziyinhloko zokukhiqiza okuhlakaniphile. Le mikhakha ihlanganisa i-petroleum, petrochemical, chemical, papermaking, ukuvikelwa kwemvelo, amandla, amandla kagesi, izimayini, i-metallurgy, imithi, ukudla nezinye izimboni.
Ngokuvumelana ne "China Control Valve Market Research Report" ye-ARC, imakethe yamavalve okulawula yasekhaya izodlula amaRandi ayizigidi eziyizinkulungwane ezimbili ngo-2019, ngokunyuka konyaka ngonyaka okungaphezu kuka-5%. Kulindeleke ukuthi izinga lokukhula elihlanganisiwe ngonyaka libe ngu-5.3% eminyakeni emithathu ezayo. Imakethe yama-valve okulawula okwamanje iphethwe yimikhiqizo yangaphandle. Ngo-2018, u-Emerson wahola i-valve yokulawula ephezulu ngesabelo semakethe esingu-8.3%. Ngokusheshisa ukushintshwa kwasekhaya kanye nokuthuthukiswa kokukhiqiza okuhlakaniphile, abakhiqizi be-valve basekhaya banethuba elihle lokukhula.
Ukushintshwa kwasekhaya kwama-hydraulic valves kuyasheshiswa. Izingxenye zeHydraulic zisetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zemishini yokuhamba, imishini yezimboni kanye nemishini emikhulu. Izimboni ezansi nomfula zihlanganisa imishini yokwakha, izimoto, imishini yensimbi, amathuluzi emishini, imishini yezimayini, imishini yezolimo, imikhumbi, nemishini kaphethiloli. Ama-valve angama-hydraulic ayizici ezibalulekile ze-hydraulic. Ngo-2019, ama-hydraulic valves abalelwa ku-12.4% yenani eliphelele lokukhishwa kwezingxenye ezibalulekile ze-hydraulic core yaseChina (Hydraulic Pneumatic Seals Industry Association), ezinosayizi wemakethe olinganiselwa kuma-yuan ayizigidi eziyizinkulungwane eziyi-10. Njengamanje, amavalvu ezwe ami asezingeni eliphezulu athembele ekuthengisweni kwamanye amazwe (ngonyaka ka-2020, ukuthunyelwa kwamanye amazwe kwamavalvu e-hydraulic transmission valve bekungama-yuan ayizigidi ezingama-847, futhi ukuthengwa kwamanye amazwe kwakungaphezulu kwama-yuan ayizigidi eziyizinkulungwane eziyi-9.049). Ngokusheshisa ukushintshwa kwasekhaya, imakethe yezwe lami yama-hydraulic valve ikhule ngokushesha.
