Iivalvu zimveliso ezinengeniso ephantsi, kwaye ukhuphiswano lwemarike lubukhali kakhulu.Ngokumalunga nokuhanjiswa kwemarike yevalvu, isekwe ikakhulu kulwakhiwo lweeprojekthi zobunjineli.Abona basebenzisi baninzi beevalvu lishishini lepetrochemical, icandelo lamandla, icandelo lesinyithi, ishishini lemichiza kunye necandelo lokwakha ezidolophini.Ishishini lepetrochemical ikakhulu lisebenzisa i-API iivalvu zesango eziqhelekileyo, iivalvu zeglowubhu kunye nezivalo zokujonga;Icandelo lamandla ikakhulu lisebenzisa iivalvu zesango loxinzelelo lobushushu obuphezulu, iivalvu zeglowubhu, iivalvu zokutshekisha kunye neevalvu zokhuseleko kwizikhululo zamandla kunye nezivalo zebhabhathane ezinoxinzelelo oluphantsi kunye neevalvu zesango zonikezelo lwamanzi kunye neevalvu zokuhambisa amanzi;ishishini imichiza ikakhulu isebenzisa Stainless steel isango iivalvu, iivalvu zeglowubhu, iivalvu zokutshekisha;Ishishini le-metallurgical lisebenzisa ubukhulu becala iivalvu zebhabhathane ezinoxinzelelo oluphantsi, i-oxygen shut-off valves kunye ne-oxygen ball valves;amasebe okwakha ezidolophini ikakhulu asebenzisa iivalvu zoxinzelelo oluphantsi, njengemibhobho yamanzi etephu yasezidolophini ikakhulu asebenzisa iivalvu zesango ezinobubanzi obukhulu, kwaye ulwakhiwo lwezakhiwo lusebenzisa ikakhulu umgca ophakathi Kwiivalvu zebhabhathane, iivalve zebhabhathane ezitywiniweyo zentsimbi zisetyenziselwa ukufudumeza idolophu;iivalvu zesango elisicaba kunye neevalvu zebhola zisetyenziswa ikakhulu kwimibhobho yeoli;iivalve zebhola zensimbi ezingenasici zisetyenziswa ikakhulu kwishishini lamayeza;iivalvu zebhola zensimbi ezingenasici zisetyenziswa ikakhulu kushishino lokutya.Iivalvu zisetyenziswa kakhulu kushishino lonyango lwamanzi, ikakhulu iimveliso zevalve ezinoxinzelelo oluphantsi, ezinjengeevalve zebhabhathane, iivalvu zesango, kunye neevalvu zokujonga.Kuyaqondwa ukuba ngoku kukho iinkampani ezingaphezulu kwe-2,000 zevalve ezinomlinganiselo othile kwimarike, uninzi lwazo zifumaneka eJiangsu, eZhejiang naseCentral Plains.Ngenxa yeemfuno ezisezantsi kumxholo weteknoloji yemveliso, ukhuphiswano lukhulu.

Ukususela kwiminyaka yoo-1980, ilizwe lam laqalisa ukuququzelela amashishini angundoqo ukwazisa iteknoloji ephucukileyo kunye nezixhobo zokulungisa ezifana noyilo kunye nobugcisa beemveliso ezifanayo ezivela kumazwe angaphandle, ukuze iteknoloji yokuvelisa ivalve yelizwe lam kunye nomgangatho wemveliso ziye zaphuculwa ngokukhawuleza, kwaye ngokusisiseko ifikeleleke. inqanaba lamazwe angaphandle ngeminyaka yoo-1980.Okwangoku, abavelisi beevalvu ezingundoqo basekhaya baye bakwazi ukuyila kunye nokwenza iivalvu ezahlukeneyo ngokuhambelana nemigangatho yamazwe ngamazwe efana nemigangatho yezizwe ngezizwe ye-ISO, imigangatho ye-DIN yaseJamani, imigangatho ye-AWWA yaseMelika, kunye nezinye iimveliso zabakhiqizi zifikelele kwinqanaba eliphezulu lamazwe ngamazwe.Nangona inqanaba lilonke leshishini levalvu kuNyaka omtsha liphuculwe kakhulu, umgangatho awuzinzile ngokwaneleyo, njengokubaleka, ukuvuza, ukuvuza, kunye nokuvuza kudla ngokuvela kwiivalve zasekhaya.Ukongeza, kusekho umsantsa othile phakathi kwesakhono sokuxhasa ivalvu yelizwe lam kunye namazwe aphuhlileyo.

Kwelinye icala, iimveliso zevalvu zelizwe lam zijongene namathuba amahle ophuhliso.Ngokukhutshelwa kophuhliso lwe-oyile kwiindawo ze-oyile zangaphakathi kunye nemimandla yeoli ekude nonxweme, kunye nophuhliso loshishino lwamandla ukusuka kumandla obushushu angaphantsi kwama-300,000 eekilowatts ukuya kumandla obushushu, umbane wamanzi kunye namandla enyukliya angaphezu kwama-300,000 eekilowatts, iimveliso zevalvu kufuneka zitshintshe ukusebenza kwazo kunye notshintsho oluhambelanayo. kwinkalo yesicelo sezixhobo.ipharamitha.Iinkqubo zokwakha ezidolophini ngokubanzi zisebenzisa inani elikhulu leevalvu zoxinzelelo oluphantsi, kwaye ziphuhla zijolise ekukhuselweni kwendalo kunye nokonga amandla, oko kukuthi, utshintsho olusuka kwiivalvu zesango zentsimbi ezinoxinzelelo oluphantsi ezazisetyenziswa ngaphambili ukuya kwivalvu yepleyiti yerabha ehambelana nokusingqongileyo, ibhalansi. iivalve, ivalve yentsimbi yokutywina ibhabhathane, kunye nezivalo zebhabhathane ezitywiniweyo.Ukuphuhliswa kweeprojekthi zothutho lweoyile negesi kwicala lemibhobho kufuna inani elikhulu leevalvu zesango elisicaba kunye neevalvu zebhola.Elinye icala lophuhliso lwamandla kulondolozo lwamandla, ngoko ke ngokombono wogcino lwamandla, imigibe yomphunga kufuneka iphuhliswe kwaye iphuhliswe ukuya kwiiparamitha ezingaphantsi kunye neziphezulu.

Ulwakhiwo lwesikhululo sombane luphuhla lusingise kuphuhliso olukhulu, ngoko ke iivalvu zokhuseleko lomgangatho omkhulu kunye noxinzelelo oluphezulu kunye neevalvu zokunciphisa uxinzelelo ziyafuneka, kunye neevalvu zokuvula nokuvala ngokukhawuleza nazo ziyafuneka.Ngeemfuno zeeseti ezipheleleyo zeeprojekthi, ukunikezelwa kweevalve kuye kwaphuhliswa ukusuka kwindidi enye ukuya kwiintlobo ezininzi kunye neenkcukacha.Kukho intsingiselo eyandayo yokuba iivalvu ezifunwa yiprojekthi yobunjineli zonke zibonelelwa ngumenzi wevalvu.

Kodwa kwelinye icala, kufuneka sithathe ngokungathí sina iingxaki ezininzi kwimarike yevalvu.Nanjengoko imarike yevalvu yelizwe lam idale ukuhlalisana kweenkampani eziphantsi kukarhulumente, ezidityanelweyo, ezidityanisiweyo, zamasheya kunye neenkampani zabucala.Kukhuphiswano oluqatha lweemarike, olufuna uphuhliso oluzinzileyo, iinkampani ziqwalasela le miba ilandelayo: ukusebenza nzima ukunciphisa iindleko zokuvelisa, kugxininise ekuphuculeni ukusebenza kwemveliso kunye nokusebenza kakuhle;ukuphuhlisa imveliso yobuchwepheshe obuphezulu okanye ukuvelisa iibhetshi ezincinci zeemveliso ezingekho mgangathweni;ukuphumelela isiqinisekiso somgangatho waMazwe ngaMazwe weemveliso zevalvu;iimveliso zevalvu kufuneka ziphuhlise kwicala lokhuseleko lokusingqongileyo kunye nokonga amandla.Nangona kunjalo, akunakuphepheka ukuba abanye abavelisi abanganyanisekanga abafuna inzuzo njengenjongo yabo kwaye bangathandabuzi ukulimaza umdla wabanye baphazamisa uphuhliso lwentengiso yevalufa eqhelekileyo.
