Amavalvu ayimikhiqizo enenzuzo ephansi, futhi ukuncintisana kwemakethe kushubile kakhulu.Mayelana nokusatshalaliswa kwemakethe yama-valve, isekelwe ikakhulukazi ekwakhiweni kwamaphrojekthi wobunjiniyela.Abasebenzisi abakhulu bama-valve yimboni ye-petrochemical, umkhakha wamandla, umkhakha we-metallurgical, imboni yamakhemikhali kanye nomkhakha wokwakha amadolobha.Imboni ye-petrochemical ikakhulukazi isebenzisa ama-valve esango ajwayelekile e-API, ama-globe valves nama-sheke valve;umkhakha wamandla ikakhulukazi usebenzisa amavalvu esango lomfutho wezinga lokushisa eliphezulu, amavalvu eglobhu, amavalvu okuhlola kanye namavalvu okuphepha eziteshini zikagesi kanye namanye amavalvu ovemvane anengcindezi ephansi namavalvu esango ukuze kuphakelwe amanzi kanye namavalvu okudonsa amanzi;imboni yamakhemikhali ikakhulukazi isebenzisa amavalvu esango lensimbi engagqwali, ama-globe valves, ama-valve okuhlola;imboni ye-metallurgical ikakhulukazi isebenzisa amavalvu ovemvane anobukhulu obuncane anomfutho ophansi, amavalvu okuvala umoya komoya kanye namavalvu amabhola omoya-mpilo;iminyango yokwakha yasemadolobheni ikakhulukazi isebenzisa ama-valve anengcindezi ephansi, njengamapayipi amanzi kampompi asemadolobheni ikakhulukazi asebenzisa ama-valve esango anobubanzi obukhulu, futhi ukwakhiwa kwebhilidi kusebenzisa umugqa omaphakathi Kumavalve ovemvane, ama-valve uvemvane avalwe ngensimbi asetshenziselwa kakhulu ukushisisa amadolobha;ama-valve esango ayisicaba kanye nama-ball valves asetshenziselwa ikakhulukazi amapayipi kawoyela;ama-valve ebhola ensimbi engenasici asetshenziswa kakhulu embonini yezemithi;ama-valve ebhola ensimbi engenasici asetshenziswa kakhulu embonini yokudla.Amavalvu asetshenziswa kakhulu embonini yokwelapha amanzi, ikakhulukazi imikhiqizo yamavalvu anomfutho ophansi, njengamavaluvu ovemvane, amavalvu esango, namavalvu okuhlola.Kuyaqondakala ukuthi okwamanje kunezinkampani zama-valve ezingaphezu kwe-2,000 ezinezinga elithile emakethe, iningi lazo ezitholakala eJiangsu, Zhejiang naseCentral Plains.Ngenxa yezidingo eziphansi uma kuqhathaniswa zokuqukethwe kobuchwepheshe bomkhiqizo, umncintiswano ushube kakhulu.

Kusukela ngeminyaka yawo-1980, izwe lami laqala ukuhlela amabhizinisi abalulekile ukwethula ubuchwepheshe obuphambili kanye nemishini yokucubungula efana nokuklanywa nobuchwepheshe bemikhiqizo efanayo evela phesheya, ukuze ubuchwepheshe bokukhiqiza ama-valve bezwe lami kanye nekhwalithi yomkhiqizo kuye kwathuthukiswa ngokushesha, futhi sekufinyeleleke. izinga lamazwe angaphandle ngeminyaka yawo-1980.Njengamanje, abakhiqizi bama-valve abalulekile basekhaya bakwazile ukuklama nokwenza ama-valve ahlukahlukene ngokuhambisana nezindinganiso zamazwe ngamazwe njengezindinganiso zamazwe ngamazwe ze-ISO, izindinganiso ze-DIN zaseJalimane, izindinganiso ze-AWWA zaseMelika, kanye nemikhiqizo ethile yabakhiqizi isifinyelele ezingeni eliphezulu lamazwe ngamazwe.Nakuba izinga eliphelele lemboni yama-valve oNyakeni Omusha liye lathuthukiswa kakhulu, ikhwalithi ayizinzile ngokwanele, njengokugijima, ukuvuza, ukuconsa, nokuvuza kuvame ukuvela kuma-valve asekhaya.Ngaphezu kwalokho, kusekhona igebe elithile phakathi kwamakhono okusekela ama-valve ezwe lami namazwe athuthukile.

Ngakolunye uhlangothi, imikhiqizo yamavalvu yezwe lami ibhekene namathuba amahle okuthuthuka.Ngokudluliswa kokuthuthukiswa kukawoyela emasimini kawoyela amaphakathi nezwe nasezindaweni zikawoyela ezingasogwini, kanye nokuthuthukiswa kwemboni yamandla kagesi ukusuka kumandla ashisayo angaphansi kuka-300,000 kilowatts kuya kumandla ashisayo, amandla aphehlwa ngamanzi namandla enuzi angaphezu kuka-300,000 kilowatts, imikhiqizo yamavalvu kufanele futhi iguqule ukusebenza kwayo nezinguquko ezihambisanayo. emkhakheni wokusetshenziswa kwemishini.ipharamitha.Izinhlelo zokwakha zasemadolobheni ngokuvamile zisebenzisa inqwaba yamavalvu anomfutho ophansi, futhi zithuthukela ekuvikelweni kwemvelo nokonga amandla, okungukuthi, uguquko olusuka kumavalvu esango lensimbi anengcindezi ephansi ayesetshenziswa esikhathini esidlule ukuya kuma-valve amapuleti enjoloba avumelana nemvelo, ibhalansi. ama-valve, ama-valve uvemvane ophawu lwensimbi, nama-valve uvemvane ophawu oluphakathi.Ukuthuthukiswa kwamaphrojekthi okuthutha uwoyela negesi lapho kuqondiswa khona amapayipi kudinga inani elikhulu lama-valve esango eliyisicaba kanye nama-ball valves.Olunye uhlangothi lokuthuthukiswa kwamandla ukongiwa kwamandla, ngakho-ke ngokombono wokongiwa kwamandla, ama-steam trap kufanele athuthukiswe futhi athuthukiswe ukuze afinyelele kumapharamitha aphezulu angaphansi nokucasisa kakhulu.

Ukwakhiwa kwesiteshi sikagesi kuthuthukela ekuthuthukisweni kwezinga elikhulu, ngakho-ke amavavu okuphepha anezinga elikhulu kanye nomfutho ophezulu kanye namavalvu okunciphisa umfutho ayadingeka, namavalvu okuvula nokuvala ngokushesha nawo ayadingeka.Ngezidingo zamasethi aphelele wamaphrojekthi, ukuhlinzekwa kwama-valve kuye kwathuthukiswa kusuka ezinhlobonhlobo ezihlukene kuya ezinhlobonhlobo eziningi kanye nokucaciswa.Kunomkhuba okhulayo wokuthi ama-valve adingwa iphrojekthi yobunjiniyela wonke ahlinzekwa ngumkhiqizi wamavalvu.

Kodwa ngakolunye uhlangothi, kufanele sithathe ngokungathí sina izinkinga eziningi emakethe ye-valve.Njengoba imakethe yamavalvu yezwe lami isungule ukuhlalisana kwezinkampani zikahulumeni, ezihlangene, ezihlangene, zamasheya kanye nezinkampani ezizimele.Emncintiswaneni oqinile wezimakethe, odinga ukuthuthukiswa okuqhubekayo, izinkampani zinaka lezi zindaba ezilandelayo: ukusebenza kanzima ukuze kuncishiswe izindleko zokukhiqiza, kugxile ekuthuthukiseni ukusebenza komkhiqizo nokusebenza kahle;ukwakha imikhiqizo yobuchwepheshe obuphezulu noma ukukhiqiza amaqoqo amancane emikhiqizo engajwayelekile;ukuphasisa isitifiketi sekhwalithi samazwe ngamazwe semikhiqizo yamavalvu;imikhiqizo yama-valve kufanele ithuthuke ibheke ekuvikelweni kwemvelo nokonga amandla.Kodwa-ke, akunakugwenywa ukuthi abanye abakhiqizi abangathembekile abafuna inzuzo njengenhloso yabo futhi abangangabazi ukulimaza izithakazelo zabanye baphazamisa ukuthuthukiswa kwemakethe yomkhiqizo we-valve evamile.
