IValve yeSango eNyangelwe kukuMhlwa

Siyimveliso yevalvu yendawo ene-ISO epheleleyo, i-CE kunye neziqinisekiso ze-API. Sijonga zonke izixhobo ze-alloy ezingenayo kwaye sivavanya yonke ivalve egqityiweyo yokutywina ngokucokisekileyo ngaphambi kokuthunyelwa. Sivulelekile kwi-OEM kunye ne-ODM tweaks kwi-alloys yevalve kunye neziphelo zeflange, ngaphandle kwemida engqongqo yeodolo. Iivalvu zethu zamasango ezikwaziyo ukudleka zithengiselwa amazwe amaninzi, kwaye abathengi bezityalo zemichiza bahlala bebuya ukuze baphinde baodole.

Zeziphi iialloyi zomzimba zevalvu ezisebenza ngcono xa uphethe inkqubo yemithombo yeendaba eyonakalisayo?

Sibonelela ngoluhlu olupheleleyo lweealloyi ezikwaziyo ukumelana nomhlwa ezilungiselelwe ulwelo lweekhemikhali ezahlukeneyo ukwandisa ubomi benkonzo yevalvu. CF8, CF8M kunye CF3M steel stainless suit ethambileyo acid, alkali buthathaka kunye namanzi kunye namanqanaba chloride eliphantsi. I-alloy 20 isebenza ngokugqwesileyo kwimibhobho ethwele i-nitric exubeneyo kunye ne-asidi ye-sulfuric, ukuxhathisa i-corrosion efanayo phantsi kweemeko zekhemikhali ezinzima. Imathiriyeli ye-Titanium lolona khetho luphezulu lwamanzi olwandle, i-brine egxininisiweyo kunye nemithombo yeendaba eneklorin egqobhoza ngokulula intsimbi eqhelekileyo engenasici. Kumphezulu wokutywina, zonke iiweji kunye nezihlalo zevalvu zogqunywe nge-Stellite okanye i-alloy C hard alloy ukuze ime i-abrasive kunye ne-corrosion medium washout.

Iimpawu eziphambili

Ngawaphi amanyathelo asebenzayo endinokuthi ndiwathathe ukuze ndinciphise umonakalo we-corrosion kunye nokwandisa ubomi benkonzo yeevalvu zesango?

Okokuqala, khetha i-alloy yomzimba ehambelanayo ngokwendawo yakho ethile, ubushushu kunye noxinzelelo; iivalvu zentsimbi zekhabhoni ezingahambelaniyo ziya konakala ngokukhawuleza kwiindawo ezineasidi okanye amanzi etyuwa. Okwesibini, khetha i-alloy epheleleyo eqinileyo yangaphakathi kwiindawo zangaphakathi kune-carbon steel wedges, njengoko umphezulu wokutywina unempembelelo ephakathi. Okwesithathu, fakela iigaskets ze-PTFE zemvulophu phakathi kweeflange ukwahlula ulwelo oludlayo kubuso besinyithi kwaye uthintele ukubola kwemingxuma. Okwesine, musa ukuyishiya ivalve intywiliselwe ngokuyinxenye kulwelo olunohlwayo olungacocwanga ixesha elide lokungenzi nto. Okwesihlanu, kwiivalvu ezifakwe ngaphandle okanye ngaphandle konxweme, jonga umphezulu wesiqhelo kunye nokugcinwa kokhuselo lokukhusela rhoqo.

Ndingamfumana phi umenzi ozinzileyo, ochwepheshile obonelela ngeevalvu zesango elikwaziyo ukumelana nokudleka?

IQela le-Huadu Valve elizinze e-Wenzhou, e-China, ngumenzi wakho othe ngqo othenjiweyo weevalvu zesango lokuchasana nomhlwa. Sibambe i-ISO epheleleyo, i-CE kunye nezatifikethi zemveliso ye-API. Siyazilungisa iivalvu ukuze zilungele ukuseta imibhobho yakho, ukusuka ekutshintsheni iialloyi ezichasene nomhlwa ukuya ekutshintsheni iintlobo zeflange kunye noqhagamshelo oluphela. Sithatha iiodolo zovavanyo ezincinci kunye neeodolo zeprojekthi ye-OEM/ODM enkulu ngokufanayo. Ivalve nganye ifumana uhlalutyo lwezinto kunye novavanyo olungqongqo lokuvuza koxinzelelo ngaphambi kokuba ipakishwe kwaye ithunyelwe phesheya.

Ndingayisebenzisa le valve yokunqanda ukubola ukulawula ukuhamba okanye ukulungelelanisa uxinzelelo lwemibhobho?

Le valve yesango yenziwe kuphela ukuvula ngokupheleleyo okanye ukuvala ngokupheleleyo imibhobho. Ayinakusetyenziselwa ukuthontsiza ukuqukuqela okanye ukuphungula uxinzelelo. Ukuba ugcina ivelufa ivulekile ngokuyinxenye, umhlwa oqukuqelayo uya kuthi gqolo ukhuhla iiweji zesinyithi ezitywina nzima, nto leyo ebangela ukurhawuka okungenakulungiseka komphezulu kunye nokuvuza okuzingileyo kwangaphakathi. Ukuba ufuna ukuhamba okuchanekileyo okanye ukulawula uxinzelelo, iivalve ezizimeleyo ezilawulayo kufuneka zixhotyiswe ngokwahlukileyo.

Ngawaphi amacandelo emizi-mveliso amkela ngokubanzi iivalvu zesango ezimelana nomhlwa kwimibhobho yazo yemveliso?

Ezi zivalo zesango lokunqanda ukubola zizixhobo eziyimfuneko kumashishini amaninzi aneemeko ezinzima. Zisetyenziswa kakhulu kwizityalo zokusetyenzwa kweekhemikhali ezine-asidi kunye nemigca yokuhanjiswa kwealkali, izikhululo zokukhutshwa kwamanzi olwandle, iinkqubo zokubuyisela amanzi amdaka, iindawo zokucocwa kwamanzi amdaka kwimizi-mveliso, iiprojekthi zaselwandle ezingaselunxwemeni, kunye neendibano zocweyo zokuvelisa amayeza ezithutha i-chloride etyebileyo kunye nemathiriyeli ekrwada ekrwada.
