Iimveliso zevalvu ziyancipha imfuno yamazwe ngamazwe, ukuphucula ukukhuphisana yeyona nto iphambili

I-valve yinxalenye ebalulekileyo yesethi enkulu epheleleyo yezixhobo, ezisetyenziselwa ubukhulu bepayipi (izinto eziphathekayo, amanzi, umphunga, umoya kunye neoli, njl.) Ukunqunyulwa, ukuxinzelela, ukulawula uxinzelelo kunye nokutshintsha indlela yokuhamba.
Iindidi zeValve kunye neenkcukacha, ukusetyenziswa okubanzi, ukusetyenziswa okukhulu, kunokwahlulwa kwiivalve zoshishino kunye neevalvu zomphakathi. Iivalvu ze-industrial ikakhuluesetyenziselwa ukulungelelanisa ukuhamba okuphakathi, uxinzelelo, ubushushu, inqanaba lolwelo kunye nezinye iiparameters zenkqubo kwintsimi yolawulo lwenkqubo yokuzenzekelayo.
Kwimarike yevalvu yemizi-mveliso yehlabathi, icandelo le-oyile negesi, kubandakanywa ukomba kunye nokuveliswa, uthutho kunye neekhemikhali zepetroli, zenza umlinganiselo ophezulu wemfuno, elandelwa ngamacandelo amandla kunye namandla kunye neekhemikhali. Kwintsimi yokusetyenziswa kweevalvu zoshishino zasekhaya, iikhemikhali, amandla, amandla kunye ne-oyile kunye namashishini egesi nawo awona mashishini aphambili kwiintengiso zevalve.
Kule minyaka imbalwa izayo, kunye nophuhliso olukhawulezayo loqoqosho lwethu kunye nokuphuculwa kwesidanga se-automation degree, inguqu kunye nokuphuculwa kweshishini lethu lokwenziwa kwezixhobo, kunye notyalo-mali lwesizwe kwi-oyile negesi, i-petrochemical, ukhuseleko lokusingqongileyo, umbane, i-metallurgy kunye namanye amasimi ayaqhubeka ukukhula, ubungakanani bentengiso yevalvu yethu yeshishini buya kuhlala bukhula ngokukhawuleza.
Okwangoku, amashishini omqolo wemveliso yevalvu yaseTshayina akwazi ukuyila nokwenza zonke iintlobo zeevalvu ngokwemigangatho yezizwe ngezizwe ye-ISO, imigangatho yeDIN yaseJamani, imigangatho ye-AWWA yaseMelika kunye neminye imigangatho yamazwe ngamazwe, abanye abavelisi beemveliso baye bafikelela kwinqanaba eliphezulu lamazwe ngamazwe. umgangatho woshishino lwevalvu uphuculwe kakhulu, kwaye ezinye iimveliso nazo ziya kwiimarike zaphesheya.
Kodwa xa kuthelekiswa neemveliso zangaphandle, ukhuphiswano lwemarike yevalufa yelizwe lethu lubukhali, amashishini entengiso anomlinganiselo omncinci, aphakathi kunye namashishini amancinci ajonga ngaphezulu kwe-90%, uninzi lwamashishini asemva kwinqanaba letekhnoloji, ikakhulu agxile kwisiphelo esisezantsi. imarike. Oku kukhokelela ekunqongophaleni kokhuphiswano lweemveliso zesivalo zaseTshayina kwimarike yamazwe ngamazwe kunye nokungabikho kophando lwemveliso kunye nophuhliso.
Kwiminyaka emibini edlulileyo, iye yachatshazelwa yingxabano yorhwebo lwamazwe ngamazwe, imfuno yamazwe ngamazwe yeemveliso ze-valve yaseTshayina iye yatshitshiswa, urhwebo lwamazwe ngamazwe lujongene nemingeni ethile. Ngokutsho kwedatha yamasiko, ixabiso lokuthumela ngaphandle kweshishini le-valve yaseTshayina litshintshile kwaye lenyuka ukusuka kwi-2017 ukuya kwi-2019. Ngo-2018, yayiyi-16.624 yeebhiliyoni zeedola, kunye nokukhula konyaka-ngonyaka we-13.5%. Ngo-2019, inani lilonke lokuthumela ngaphandle kumzi-mveliso wevalvu wase-China wehle waya kwi-16.231 yeebhiliyoni zeedola, wehla nge-0.02% ngonyaka.
Kulo mxholo, amashishini evalvu yaseTshayina kufuneka aphucule itekhnoloji yemveliso kunye nomgangatho, andise uphando lwemveliso kunye nophuhliso lwetekhnoloji, kwaye afumane inqanaba lamazwe ngamazwe ngokukhawuleza ukuphucula ukhuphiswano lwamazwe ngamazwe.
Iingcali ezifanelekileyo zibonise ukuba amashishini afanelekileyo kufuneka akhawulezise ukuphuculwa kwemizi-mveliso kwaye aqhubele phambili kwicala leemveliso zevalvu ephakathi, ezifana ne-oyile, amandla enyukliya kunye neminye imimandla engundoqo yophuhliso lwesizwe. Amandla okuthengisa okutshintshwa kweevalvu zangaphakathi ngaphandle kokuhoywa.
Okwangoku, imeko yezoqoqosho yaseTshayina kunye neentlobo ngeentlobo zemigaqo-nkqubo iyaqhubeka nokuxhamla, ibonelela ngezinto ezithandekayo zophuhliso kushishino lwesivalo saseTshayina. Nangona ivalve yelizwe lethu xa ithelekiswa namazwe angaphandle kukho umsantsa othile, kodwa eyona nto iphambili kwishishini levalvu yelizwe lethu kukuphucula ngakumbi umgangatho wemveliso kunye nomxholo wobugcisa, kuphela isiseko esiluqilima sokuhlola okungapheliyo kunye nokutsha, ivalve yelizwe lethu. uphawu lunokuba ludumo phesheya, kwaye lufumane imarike ngakumbi.
