I-Hard Seal Globe Valve

Iza nezinto ezixhumene nama-flanged futhi ifaka ukwakhiwa kokuvalwa kwensimbi ukusuka ensimbi kuye kwensimbi.Inqamula ukugeleza koketshezi ngokuphelele ngokungavuzi kweziro futhi ikuvumela ukuthi ulungise ngokunembile izinga lokugeleza ngaphakathi kwamapayipi. Izinguqulo ze-WCB zisebenza kahle ku-steam nemidiya yezimboni evamile, kuyilapho amamodeli ensimbi engagqwali emelana noketshezi olubolayo. Le valve ilingana kahle ne-petrochemical, imboni yamandla, i-metallurgy kanye namaphrojekthi wokuhlanza amanzi ezimbonini.

Singumkhiqizi wamavalvu ochwepheshe onezitifiketi eziphelele ze-ISO, CE kanye ne-API. Sisebenzisa amasethi agcwele emishini yemishini ye-CNC ethuthukisiwe kanye nezinhlelo eziqinile zokuhlola ikhwalithi yenqubo ephelele ukuze siqinisekise ukusebenza komkhiqizo okungaguquki kuwo wonke amabanga wezinto ezibonakalayo. Izinsiza zangokwezifiso ze-OEM ne-ODM ziyatholakala nge-MOQ eguquguqukayo ukuze kuhlangatshezwane nezidingo zephrojekthi ezihlukene. Ama-valve ethu ahlala isikhathi eside embulunga eqinile athunyelwa ezimakethe emhlabeni wonke futhi azuza impendulo engaguquki eyakhayo kubalingani bomhlaba wonke.

Izimfanelo Ezibalulekile

Uyini umehluko oyinhloko phakathi kwe-valve yeglobu ye-hard seal kanye ne-soft seal globe valve?

Ngokungafani namavalvu embulunga yophawu oluthambile athembele ku-PTFE, izingxenye zenjoloba noma zepulasitiki zokuvala, amavalvu ethu eglowubhu yophawu oluqinile asebenzisa ukutywina okuqinile kwensimbi ukuya kwensimbi, ane-stellite alloy enobuso obuqinile kudiski yevalvu kanye nesihlalo. Amamodeli athambile ama-seal anqunyelwe ekamelweni lokushisa, ukucindezela okuphansi kanye nemidiya ehlanzekile. Uma kuqhathaniswa, uhlaka lwensimbi oluqinile luziqhayisa ngokuvelele izinga lokushisa eliphezulu, ukubekezelela ukucindezela okukhulu, ukumelana nokugqoka nokusebenza kokulwa nokuguguleka. Ngeke ishise, liwohloke noma livuze ezindaweni ezinolaka njengesitimu esigcwele izinga lokushisa eliphezulu, igesi yasezimbonini enomfutho ophezulu kanye nemithombo yezindaba enukayo enezinhlayiyana, igcine ukuvalwa okuqinile okuthembekile kokusebenza kwemboni yesikhathi eside.

Yiziphi izinto zomzimba engingazikhethela lo mkhiqizo, futhi iyiphi elingana nepayipi lami?

Sihlinzeka ngezinto ezimbili ezisetshenziswa kabanzi zama-valve ukufanisa izimo zokusebenza ezihlukene zezimboni: i-WCB carbon steel, kanye ne-304 kanye ne-316L yensimbi engagqwali.

I-WCB carbon steel inesakhiwo esiqinile kanye namandla amakhulu okuthwala ingcindezi ngentengo yokuncintisana. Isebenza kahle ngemidiya engagqwali njengesitimu sezimboni, amanzi ajikelezayo, umoya ocindezelwe kanye nowoyela wezimboni ojwayelekile, futhi ivamise ukusetshenziswa eziteshini zikagesi, amapayipi okufudumeza kanye nezinhlelo zamapayipi ezivamile zasefekthri.

Uma ipayipi lakho liphethe uketshezi olune-asidi, i-alkaline noma i-oxidizing, khetha insimbi engagqwali engu-304 noma engu-316L. Lawa mabanga amelana nokugqwala nokuguguleka kwamakhemikhali kahle kakhulu, okuwenza afaneleke kakhulu izitshalo zamakhemikhali, imigqa yemithi, ukuhlanzwa kwamanzi angcolile kanye nezimo zokusebenza zasogwini.

Kungakhathaliseki ukuthi ukhetha yiphi impahla yomzimba, zonke izingxenye zokuvala zangaphakathi ziza nembondela ye-stellite hardfacing. Wonke ama-valve athola ukwelashwa okufanayo kwembondela ye-stellite, ngakho-ke yonke iyunithi inikeza ukumelana nokugqokwa okuqinile kanye nemiphumela yokuvala engaguquki.

Ingabe ama-valve eglobu ensimbi eqinile ayavala ngaphandle kokuvuza?

Amavalvu amaningi ensimbi aqinile adonsa kanzima ngenxa yokuvuza okuncane ngenxa yomshini omahhadlahhadla kanye nokunemba kokufakwa kwawo kahle. Kodwa-ke, imikhiqizo yethu isebenzisa ubuchwepheshe obuqinile bokwenza i-stellite kanye nenqubo yokugeqa enembile, ehlangabezana ngokugcwele nezindinganiso zokuvala eziqinile ze-API. Ihlukile ekubekweni uphawu okunwebekayo kwama-valve ophawu athambile, ukuvala kwethu kwensimbi kuncike ekufakweni okunembayo okuphezulu. Sisebenza ngomshini zonke izingxenye ngemishini ye-CNC enembile futhi sigaya izindawo zokuvala izikhathi eziningi ngesandla. Lokhu kuvumela i-valve disc nesihlalo kuhlangane ngokuqinile ngaphandle kwezikhala. I-valve ibamba ukuvuza kwe-zero ngaphansi kwezinga lokushisa elijwayelekile kanye nengcindezi, futhi uphawu luhlala luthembekile ngisho nangemva kwezinkulungwane zemisebenzi evaliwe.

Yiziphi izimo zokusebenza ezisebenzayo kanye nemikhawulo yokusetshenziswa kwama-valve embulunga yophawu oluqinile?

Lolu chungechunge lwama-valve embulunga yophawu oluqinile lwenzelwe ngokukhethekile izinga lokushisa eliphezulu, ingcindezi ephezulu, izimo zokusebenza zezimboni ezilumayo nezinzima. Ivumelana nemidiya ehlukahlukene eyinkimbinkimbi efana ne-high-temperheat superheated, uwoyela ongahluziwe, igesi yemvelo, isixazululo esicekela phansi samakhemikhali, i-fine particle slurry kanye negesi yezimboni exubile. Isetshenziswa kakhulu ku-petrochemical, ukukhiqiza amandla ashisayo, i-metallurgy, izimayini, ukwelashwa kwamanzi ezimbonini kanye namaphrojekthi amasha wamandla.

Kungani ama-valve eglowubhu yophawu oluqinile enokuphila kwesevisi okude kunamavalvu ajwayelekile ezimbonini?

Impilo ende yesevisi iqinisekiswa ngezinzuzo ezimbili zobuchwepheshe bezinto ezibonakalayo nezokukhiqiza. Okokuqala, umzimba we-valve wamukela inqubo yokuphonsa ebalulekile enesakhiwo sangaphakathi esihlangene, azikho izimbobo zesihlabathi noma i-porosity, kanye namandla anamandla okuthwala ingcindezi kanye ne-anti-deformation. Okwesibili, izingxenye eziyisisekelo zokuvala zimbozwe nge-high-hardness stellite alloy, okumelana nokugqoka nokuzinza kwezinga lokushisa eliphezulu kungcono kakhulu kunezindawo ezijwayelekile zokuvala insimbi engagqwali. Ngaleso sikhathi, isakhiwo sokugeleza esiyingqayizivele sevalvu yembulunga sigwema umthelela oqondile omaphakathi endaweni yokuvala, kunciphisa ukuhuzuka ngempumelelo.

Ingabe ama-valve embulunga yophawu oluqinile ayinkimbinkimbi ukuwafaka nokuyinakekela?

Lutho neze. Wonke amavalvu ethu embulunga yophawu oluqinile asebenzisa ukuxhumana kwe-flange okujwayelekile, okuhambisana ne-API yendawo yonke, i-CE kanye nezindinganiso zamazwe ngamazwe ze-ISO, ezihambisana nezinhlelo eziningi zamapayipi ezimboni zomhlaba wonke futhi ezisekela ukushintshwa okuqondile esizeni kanye nokufakwa ngokushesha. Isakhiwo se-modular esibalulekile silula futhi sinengqondo, sinesiqu se-valve ekhishwayo, i-disc kanye nesihlalo sokushintshwa okuyingxenye okulula. Ukunakekelwa kwansuku zonke kulula kakhulu: ukususwa okuvamile kuphela kokungcola kwamapayipi kanye nokugcotshwa kwesiqu esifanele kuyadingeka, konga ngempumelelo isikhathi kanye nezindleko zangemuva kokuthengisa.
