Single eccentric butterfly valve
Kuti ugadzirise dambudziko rekuwedzera pakati pe diski uye chigaro chevhavha yevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhuhavhavhuvhuvhuvhuf Ngahali Mudzimu. Kuparadzira uye kuderedza yakawandisa extrusion yepamusoro uye yakaderera migumo ye butterfly plate uye chigaro chevharuvhu. Zvisinei, nekuda kwechimiro chimwe chete eccentric, chiitiko chekutsvaira pakati pe diski uye chigaro chevhavha hachiperi panguva yose yekuzarura nekuvhara kwevhavha, uye kushandiswa kwekushandiswa kwakafanana neiyo concentric butterfly valve, saka haina kushandiswa zvakanyanya.
Kaviri eccentric butterfly valve
Pahwaro hweimwe eccentric butterfly valve, ndizvo iyo kaviri eccentric butterfly valve iyo inoshandiswa zvakanyanya panguva ino. Chimiro chayo chechimiro ndechekuti shaft yepakati yevhavha stem inotsauka kubva pakati pe disc uye pakati pemuviri. Mhedzisiro yekaviri eccentricity inoita kuti diski iparadze kubva pachigaro chevharuvhu pakarepo mushure mekuvhurwa kwevhavha, iyo inobvisa zvakanyanya zvisingakoshi zvakanyanyisa extrusion uye kukwenya pakati pe disc nechigaro chevhavha, inoderedza kuvhurika kwekuvhara, inoderedza kupera, uye inovandudza hupenyu hweSeat. Kuchera kunoderedzwa zvakanyanya, uye panguva imwe chete,iyo kaviri eccentric butterfly valve inogonawo kushandisa chigaro chesimbi chevhavha, iyo inovandudza kushandiswa kwevhavhavhavhavhavha munzvimbo yepamusoro yekupisa. Zvisinei, nokuti chisimbiso chayo chisimbiso chisimbiso chekuisa chisimbiso, ndiko kuti, chisimbiso chepamusoro che disc uye chigaro chevhavha chiri mumutsara wekubatana, uye elastic deformation inokonzerwa ne disc extrusion yechigaro chevhavha inobudisa chisimbiso chekuvhara, saka ine zvinodiwa zvakanyanya zvekuvhara nzvimbo (kunyanya simbi yevhavha chigaro), yakaderera kumanikidzika inotakura simba, ndicho chikonzero netsika vanhu vane mavharuvhu emagetsi havafungi kuti vane bhotela.
Triple eccentric butterfly valve
Kuti utsungirire kupisa kwakanyanya, chisimbiso chakaoma chinofanira kushandiswa, asi huwandu hwekudonha hwakakura; kusvika zero leakage, chisimbiso chakapfava chinofanira kushandiswa, asi hachipokane nekupisa kwakanyanya. Kuti akunde kupokana kwekaviri eccentric butterfly valve, butterfly valve yaive eccentric kechitatu. Chimiro chayo chechimiro ndechekuti nepo maviri eccentric valve stem iri eccentric, iyo conical axis ye disc sealing surface inorerekera kune cylinder axis yemuviri, ndiko kuti, mushure mechitatu eccentricity, chikamu chekuisa chisimbiso che disc hachichinji. Ipapo idenderedzwa rechokwadi, asi ellipse, uye chimiro chekuisa chisimbiso chepamusoro chayo zvakare asymmetrical, rimwe divi rakarerekera kumutsetse wepakati wemuviri, uye rimwe divi rakafanana nepakati mutsara wemuviri. Hunhu hweichi chetatu eccentricity ndeyekuti chisimbiso chekuisa chisimbiso chakanyatso kushandurwa, hachisisiri chinzvimbo chisimbiso, asi chisimbiso che torsion, ndiko kuti, hachivimbi neiyo elastic deformation yechigaro chevharuvhu, asi inovimba zvizere nekusangana kwepamusoro kudzvanywa kwechigaro chevhavha kuti iite chisimbiso, Naizvozvo, dambudziko re zero chigaro chinodonhedza chinoputika mukati mesimbi, simbi inodonha uye kudonha kwesimbi. zvakaenzana nepakati pekumanikidza, iyo yakanyanya kudzvanywa uye yakakwirira tembiricha kuramba inogadziriswa zvakare nyore.
