Kaviri eccentric hard seal butterfly valveinovandudzwa zvishoma nezvishoma kubva kune yakajairika butterfly valve kuti ienderane nemamiriro akasiyana ekushanda (akadai sekushanda tembiricha uye kushanda nesimba).Iine zvakanakira chimiro chakareruka, chisimbiso chakavimbika, kuvhurwa kwechiedza, hupenyu hurefu hwebasa uye kugadzirisa kuri nyore.Parizvino, nekuvandudzwa kwehukuru-hukuru shanduko yekuputika kwesimbi yekugadzira simbi muChina, kaviri eccentric hard seal butterfly valve yakashandiswa zvakanyanya mukugovera mvura uye kudhonza, kuvaka moto kudzivirira, metallurgy uye mamwe mapaipi masisitimu.
The Working Principle:
Muchidzidzo, vharafu yeshavishavi yakajairwa yakavharwa semutsara wekubata.Ndichiri kune multi-levelkaviri eccentric simbi yakaoma chisimbiso butterfly vharafu, nzvimbo yekuisa chisimbiso inoumba bhanhire rakafara remhete kubva kumutsara wepakutanga nekuda kwechipiri eccentricity (chinzvimbo chevhavhavha inokwira kumusoro).Chero bedzi iyo yekusangana kwepamusoro peiri yekuisa chisimbiso iri mune iri bhandi remhete, kuiswa chisimbiso kunogona kuitika pasina chero clamping boka kana dhisiki yevharuvhu yavhurwa.
Panguva yekuvhurwa kwedhisiki yevharuvhu, nzvimbo dzekuvharira dzeyakajairwa vharuvhu dhisiki dzinofamba dzichitevedza tangent trajectory yeconical valve seat bhazi.Uye kune shandurudzo inowirirana pakati pezvisimbiso zviviri.Saka friction torque yakakura.Zvisinei, kushandura pakati pezvisimbiso zvepairi zvekaviri eccentric simbi yakaoma chisimbiso butterfly vharafuidiki kwazvo.Uye imwe neimwe poindi yekumusoro yekubata chisimbiso inokurumidza kupatsanurwa pamwe neiyo tangent trajectory nzira yeiyo conical valve seat bhazi.Naizvozvo, iyo friction torque idiki kwazvo, iyo inonyatso kudzikisa kupfeka pakati pekuisa chisimbiso pairi.
Mune metallurgy system, iyo double eccentric hard seal butterfly valve inonyanya kushandiswa mu preheating system uye yakaoma guruva yekubvisa system ye ironmaking blast furnace ine hombe yezita dhayamita, yakaderera kushanda kumanikidza, kuvhurika kwakaderera & kuvhara kusiyanisa kudzvanywa uye kupisa kwakanyanya (200 ° C. ~ 350°C).
Sezvokaviri eccentric hard seal butterfly valveine kuita kwakanaka kwazvo kwekuisa chisimbiso, tembiricha inoshanda, hombe yekushanda, kupikisa kupfeka, kuramba kwecorrosion uye hupenyu hurefu hwebasa.Naizvozvo, mabasa ayo akaita sevharuvhu yekupisa mhepo inovhara-vhavha, gasi rinopisa-vhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha inobvira gasi rinopinda &kubudakuvharisavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharu yekupisa kupisa,flue gasi inlet & outlet shut-off valve ye heat exchanger system uye gasi kuvhara. -vhavha yevhavha yakaoma yekubvisa guruva.
