Ivalvu yeButterfly ePhakamileyo ephindwe kabini e-Eccentric
Iivalvu yebhabhathane eqaqambileyo esebenza kakhulu kabini— ekwaziwa ngokuba yi-double offset butterfly valve — yimveliso yoyilo oluphambili lwe-double offset equka itekhnoloji ehamba phambili kwihlabathi liphela yenkonzo enzima yemizi-mveliso. Ine-shaft offsets ezimbini ezahlukeneyo ezisusa idiski kwisihlalo kwangoko xa ivulwa, zisusa ukudibana okuqhubekayo kwesihlalo ngexesha lokusebenza — inzuzo ebalulekileyo kune-concentric butterfly valves.
Uxinzelelo kwidiski lukhutshwa emva nje kokuvulwa kweedigri ezimbalwa, nto leyo enciphisa ukuguguleka kwetywina lediski kulo lonke ixesha lokusebenza kwevalvu. Le geometry ephindwe kabini inciphisa i-torque yokusebenza, inciphisa ukungqubana kunye nokuguguleka kwesihlalo, kwaye iqinisekisa ukutywinwa okuthembekileyo naphantsi kotshintsho olukhawulezileyo kubushushu okanye uxinzelelo - nto leyo eyenza ukuba ibe lolona khetho lukhethwayo kwiindawo zoshishino ezinoxinzelelo oluphezulu, ubushushu obuphezulu, kunye nokhuseleko olubalulekileyo. Ngesatifikethi se-API 607 esikhuselekileyo emlilweni kunye nesatifikethi se-ATEX, iivalvu zebhabhathane ezisebenza kakuhle eziphindwe kabini zeNortech zifanelekile kwiimeko zokusebenza ezinzima nezinobungozi.
Zonke iivalvu ziqinisekisiwe ukuba ziyasebenzaUvavanyo lobomi bemijikelo eyi-1,000,000kunye nokusebenza okuqinisekisiweyo kokungavuzi nto kwicala ngalinye, okuhlangabezana nemigangatho ephezulu yokuthembeka nokhuseleko lwexesha elide.
INortech igcina isitokhwe esikhulu seevalvu zomzimba eziphoswayo, iqinisekisaukuhanjiswa ngokukhawuleza kwiiveki ezi-3-5kwiiodolo ezininzi ezisemgangathweni.
Ijiyometri yediski ephindwe kabini— iidiski ziphuma kwisihlalo emva nje kokuvula iidigri ezimbalwa, zisusa ukungqubana kwesihlalo ngexesha lonke lokubetha ngokupheleleyo kwaye zandise ubomi besihlalo xa kuthelekiswa noyilo oluqinileyo.

Yenzelwe ukusetyenziswa ngokukhawuleza kweenkqubo zokujikeleza umoya ezifana neenkqubo zokwahlula umoya, ivalvu ingagqiba umjikelo ovulekileyo/ovaliweyo opheleleyo ngaphantsi komzuzwana omnye, kunye nobomi benkonzo obuqinisekisiweyo obufikelela kwi-1,000,000 yemijikelo yokusebenza.
Izinto zesihlalo sePPL zilinganiswe ukusebenza rhoqo ukuya kuthi ga kwi-250°C, nto leyo eyenza ivalvu ifaneleke kwiinkqubo zenkqubo zobushushu obuphezulu.
Uyilo oluyi-eccentric oluphindwe kabini lubonelela ngokutywinwa okuthembekileyo kwamanqanaba ama-6 phantsi kweemeko zoxinzelelo oluphezulu, kunye nokusebenza okuqinisekisiweyo kwiinkqubo zokupholisha i-condensate kunye nezicelo ezifanayo ezifuna amandla.
Iivalvu zenkonzo ye-oksijini zisuswa ngokupheleleyo kwaye zihlanganiswe phantsi kweenkqubo ezingqongqo zococeko, ezigubungela zonke izigaba zokulungiswa kwezakhi, ukuhlanganiswa, ukuvavanywa, kunye nokupakishwa ngokuhambelana neemfuno zenkonzo ye-oksijini.
Isatifikethi se-API 607 esikhuselekileyo emlilweni kunye nesatifikethi se-ATEX ziqinisekisa ukuba ivalvu ingasetyenziswa kwiindawo zokusebenza ezinokutsha, eziqhumayo, kunye nezo zinobungozi bomlilo.
