Ivalve licandelo lolawulo kwinkqubo yothutho yombhobho, engasetyenziselwa ukulawula ukuhamba komoya, amanzi, umphunga, imidiya eyahlukeneyo eyonakalisayo, udaka, i-oyile, isinyithi esilulwelo kunye nemidiya ye-radioactive.Kwishishini lamachiza, ukusetyenziswa kweevalvu ezinkulu.

Umzekelo, kwishishini loxubo-mayeza, linokwahlulwa ngokomgaqo wombhobho wamachiza omninzi kunye nombhobho wokulungiselela uhlobo olumbini lombhobho.Ngokomzekelo, intsimi yamachiza, ngokungafaniyo nentsimi yeziyobisi ezininzi, i-medium ukuba ithuthwe ixhaphake kakhulu, igxininiswe kakhulu emanzini athambileyo, amanzi ahlambulukileyo, amanzi okutofa, umphunga ococekileyo, inkqubo Umoya ocinezelweyo.

Nangona kunjalo, umbhobho kwishishini lamachiza kufuneka ubeke "umgangatho ococekileyo" kwindawo yokuqala, ngoko ke ishishini loxubo mayeza lineemfuno eziphezulu zokugudiswa, ukucoceka, ukucaca kunye nokumelana nokubola kwezixhobo zevalvu.

Ukuze kuhlangatyezwane kakuhle neemfuno zoshishino lwamayeza, izixhobo zevalve eziphucukileyo ziya kufakwa kwimarike yamayeza, kwaye zonke iinxalenye zeshishini levalvu zenza umsebenzi wokuguqula nokuphucula kunye nokulungelelanisa ubume bemveliso yokuphuhlisa imveliso yezixhobo ezinobukrelekrele. amalungelo epropathi.

Ukusuka kumbono wobuchule, iShishini leValve likwindawo elungileyo.Umzekelo, ukuphunyezwa kweQhinga loPhuhliso oluZinzileyo lokuHlaza kunye nokusebenza kwenyathelo le-"Belt and Road" lizise amathuba amatsha ohlengahlengiso lwezakhiwo kunye nokuphuculwa kwemizi-mveliso yoshishino lwevalvu.

Phantsi komgaqo-nkqubo olungileyo wokusingqongileyo, iValve Market Development Prospect ibanzi.Ngokwezibalo ezifanelekileyo, imakethi yevalvu yeshishini yaseTshayina iya kuzisa umjikelo omtsha womjikelo wophuhliso, imakethi yevalvu yeshishini ka-2020 iya kudlula ubungakanani beebhiliyoni ezingama-20 zeeyuan.

Okwangoku, ishishini levalvu laseTshayina likwixesha elilungileyo lophuhliso.Ngokwezibalo, kukho ngaphezu kwe-3000 amashishini okuvelisa i-valve e-China, enokuvelisaiivalve zesango, i-throttle valves,iivalve zebhola, iivalvu zeglowubhu, ivelufa butterflys, ivalve ye-diaphragm, njl.

Ukongeza, phantsi kweempembelelo zemvelaphi yemarike engentla, itekhnoloji yevalvu yaseTshayina nayo iyanyuka.Ukuthatha inqanaba letekhnoloji yeevalvu kushishino lwamayeza njengomzekelo, ukwenzela ukubonelela ngenkxaso efanelekileyo kubathengi, amanye amashishini evalve aphuhlise iimveliso ezikrelekrele.

Ngokokwaziswa kwabasebenzi bezobugcisa, iimveliso zevalve ezikrelekrele zinokulandelayoiinzuzo ezinkulu:

1. Ukukwazi ukuchonga umzimba wevalvu, i-actuator kunye nolwazi lwe-diaphragm.
2. Unokuchonga ulwazi lwemveliso kunye nolwazi lokuSinda.
3. Ngokulandelelwa kolwazi, phucula ukuthembeka kwenkqubo.
4. Ukusekwa kwamaxwebhu e-elektroniki ajongene nomsebenzi ngqo (njengamaxwebhu axhasayo).
5. Gcina ilogi, ulungiselele inkqubo yolondolozo.
6. Ukuphucula ubukrelekrele bezixhobo (isiqinisekiso sofakelo).
7. Iofisi kunye nokugcinwa kwephepha.

Nangona kunjalo, uninzi lwamashishini ethu eevalve akwinqanaba elisezantsi, amancinci, amashishini enziwe ekhaya, kunye nomlinganiselo wokuNxibelela, umgangatho wobugcisa, umgangatho wemveliso uphantsi, kunye nokungabikho kophawu olunempembelelo ngakumbi.

Kodwa kwimakethi yevalvu ephezulu, uphuhliso lwemveliso yezixhobo lunakho ukungoneli, imakethi isalawulwa lishishini eliphambili lamazwe ngamazwe, kwaye isabelo seshishini levalve yelizwe lethu sikwicala eliphantsi.Kodwa oku kukwathetha ukuba ishishini levalvu laseTshayina linophuhliso olukhulu lwemarike.

Ngokubanzi, kusekho iziphene ezine ezinkulu kushishino lwevalvu yaseTshayina, kubandakanywa ubume bemizi-mveliso obungekho ngqiqweni kunye nomthamo omkhulu;amandla abuthathaka okwenziwa ngokutsha okuzimeleyo kunye nomgangatho ophantsi wemveliso;ukungabikho kweempawu ezinempembelelo;kunye nemigangatho yoshishino olungafezekanga, ” zatsho iingcaphephe zevalvu ngakumbi kwinkalo yezobugcisa engundoqo, isabelo semarike samashishini ethu esivalufa kurhwebo lwamazwe ngamazwe asikho phezulu.

Ke ngoko, ukuba amashishini evalve afuna ukubamba isabelo semarike esithe kratya, kufuneka athathe inyathelo lokuqala lokwakha ukhuphiswano olungundoqo, kwaye agcine imvakalelo yonxunguphalo, ajolise kwimfuno yentengiso, kwaye azabalazele ukuphucula umgangatho kunye nobuchwephesha beeMveliso zeValve nge. phambili ngakumbi, iimveliso zevalve ezikrelekrele izixhobo ukuvula ucango imarike, ukunceda ukukhuthaza ishishini valve China ukuya phezulu, ulwalathiso olufikelela kude.
Lo ikwangumbono weCOVNA wequmrhu, ukuqhubeka nokuphucula umgangatho kunye netekhnoloji, ezibophelele ekuboneleleni abathengi ngeemveliso ezingcono, kunye nezisombululo ezizisebenzelayo ezikumgangatho ophezulu.
