Iivalvu zeSango eziDityanisiweyo

Njengomboneleli wevalvu waseTshayina okhethekileyo kwisixhobo sokuvula umbhobho, iHuadu Factory ivelise le Valve yeSango iWelded. Ezi iivalvu zesango lentsimbi engenasici edityaniswe ngokuwelda - ngenxa yokumelana nomhlwa kwezinto ze-CF8 kunye nokusebenza kokutywinwa okuphezulu kojongano oludityanisiweyo, ziye zaba lukhetho olusebenzayo kwimibhobho emininzi eneemfuno zokutywinwa ezingqongqo, kwaye zilungele iimeko ezahlukeneyo zokusebenza eziqhelekileyo.

Iinzuzo ezingundoqo zokuthengisa

Eyona nto ibalaseleyo yale Valve yeSango "ukutywinwa okuzinzileyo + izinto ezihlala zihleli": Yenziwe nge-CF8 yensimbi engenasici (ehambelana nezinto ezingama-304). Ngexesha lenkqubo yokufaka izinto eziphathekayo kwifektri ye-Huadu, uvavanyo lwamacandelo luqhutywa. Umxholo we-chromium-nickel udibana nomgangatho, kwaye ukuxhathisa kwe-corrosion kwanele ukusingatha iimeko zokuthutha zamanzi acocekileyo kunye neendaba ezingathathi hlangothi; ithatha indlela yokudibanisa i-welding, ibe nezithuba ezimbalwa zokutywina kunokudibanisa kwe-flange, okubangela umngcipheko ophantsi wokuvuza xa umbhobho udityanisiwe okanye uqhawulwe; kwangaxeshanye, sisakhiwo sohlobo lwe-stem, esivumela ukusebenza kwe-handwheel ukuba kubonise ngokuthe ngqo imeko yokuphakamisa i-valve stem, ukuphelisa imfuno yokuhlolwa okongeziweyo kwisimo sokutshintsha, ukwenza umsebenzi we-site ulungele ngakumbi.

IiNgcaciso zobuGcisa

Iiparamitha eziphambili zingabonwa ngokuthe ngqo kwiimpawu ezikroliweyo kumzimba we-valve: ububanzi be-DN125, iqondo loxinzelelo lwe-PN16, ukutyunjwa kwezinto eziphathekayo CF8, zonke ezi zinkcukacha eziqhelekileyo ezisetyenziswa kwimibhobho yasekhaya; i-welding interface ihambelana neemfuno zokudityaniswa kwemibhobho esemgangathweni yesizwe, kwaye akukho mfuneko yokuguqula ubungakanani bokuphela kombhobho; emva kwe-welding, inokuhlanganiswa ngokuthe ngqo kwinkqubo yepayipi ekhoyo; kudibaniswa noyilo lwesakhiwo se-stem esiveziweyo, ukuvulwa kunye nokuvala i-valve ye-valve stem kucacile, kwaye uxhulumaniso lombhobho lunokulawulwa ngokuchanekileyo ngexesha lokusebenza, ngaphandle kwesidingo sohlengahlengiso oluphindaphindiweyo.

Iinkalo zesicelo

Iimeko ezisebenzayo zale valve yesango elidityanisiweyo ikakhulu ezo zifuna ukusebenza kokutywinwa okuphezulu: njengemibhobho yokuthutha ulwelo olucocekileyo kushishino lokutya kunye namayeza (ngemathiriyeli yeCF8, ipropathi yococeko idityaniswe netywina elidityanisiweyo linokuthintela ungcoliseko oluphakathi); imibhobho yothutho yemidiya engathathi hlangothi (njengamanzi acocekileyo kunye nezinyibilikisi eziqhelekileyo) kwintsimi yeekhemikhali, i-welded interface inokunciphisa umngcipheko wokuvuza; i-medium-temperature thermal circulation pipelines kubunjineli bakamasipala, i-stem structure eveziweyo yenza kube lula kubasebenzi abakwisiza ukuba baqinisekise ngokukhawuleza isimo sevalvu; nakweminye imibhobho exhasa izixhobo zemizi-mveliso ephakathi, ukuba nje kufuneka ulawulo oluzinzileyo, le valve yesango idityanisiweyo inokulungiswa.

Iingenelo zoontanga

Xa kuthelekiswa neevalvu zesango eziqhelekileyo kwimarike, iingenelo zeeVavali zeSango likaHuadu zicace gca: Okokuqala, ukusebenza kokutywinwa koqhagamshelo oludityanisiweyo kubhetele kuneevalvu zeflange, zizenze zilungele iimeko ezinomngcipheko wokuvuza obuthathaka; okwesibini, ulawulo lomgangatho wezinto CF8 ngqongqo. Umzi-mveliso uqhuba uvavanyo kwibhetshi nganye yezinto ezikrwada, ezihlala ixesha elide kunezixhobo ezingezizo ezisemgangathweni kwiifektri ezincinci; okwesithathu, ulwakhiwo lwe-stem oluveziweyo lusebenza ngakumbi, kwaye akukho disassembly eyongezelelweyo efunekayo ekusebenzeni kwisayithi, egcina ixesha elingakumbi lokulondoloza xa kuthelekiswa ne-valve ye-stem efihliweyo.

Ixabiso kunye noThutho oluluncedo

Njengomzi-mveliso obonelelwa ngokuthe ngqo ngumvelisi wasekhaya waseTshayina, le valve yesango edityanisiweyo inexabiso eliphantse libe ngama-40% ngaphantsi kuneeVaveyi zeSango eziDityanisiweyo ezifakwe kumazwe angaphandle ezichazwe ngokufanayo. Akukho ntlawulo okanye iipremiyamu zomntu ophakathi. Ngokumalunga nomthwalo, iinkcukacha eziqhelekileyo ezifana ne-DN125 zine-inventri eqhelekileyo, kwaye umyalelo ungathunyelwa kwiintsuku ze-3. Umzimba wevalve wevalve edibeneyo uya kupakishwa ukuthintela umhlwa, kwaye imeko ye-interface ayiyi kuchaphazeleka ngexesha lokuthutha umgama omde.

Inkonzo yasemva kokuthengisa

Inkonzo ye-Huadu emva kokuthengiswa kwakhona ihambelana neemeko zokusetyenziswa kwee-valve ze-welding: Ukuba kukho ukungaqiniseki malunga neenkcukacha ze-interface ngexesha le-welding kwi-site, iqela lobugcisa liya kukhupha izikhokelo zokusebenza kwe-welding; ukuba iingxaki zokutywinwa ezinganyanzelwanga ngabantu zenzeka kwixesha lewaranti, umzi-mveliso uya kulungiselela ngokuthe ngqo ukutshintshwa; ukuthengwa ngobuninzi, iingxelo zokuhlolwa kwezinto ezihambelanayo nazo zinokubonelelwa, ukuququzelela ukwamkelwa kweprojekthi.

Xa ukhetha i-valve yesango elidityanisiweyo, amanqaku aphambili "kukutywinwa kakuhle kunye nokusebenza kakuhle". I-Huadu's Welded Gate Valves ibetha ngokuchanekileyo la manqaku mabini. Nokuba yeyokudityaniswa kweprojekthi okanye ukulungisa imibhobho, lukhetho oluthembekileyo.
