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 disc uye chigaro chevhavha hachiperi panguva yose yekuzarura nekuvhara kwevhavhavha, uye kushandiswa kwekushandiswa kwakafanana neiyo concentric butterfly valve, saka ndiyo. 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 chevhavha pakarepo mushure mekuvhurwa kwevhavha, iyo inobvisa zvakanyanya kusingakoshi yakawandisa extrusion uye kukwenya pakati pe disc nechigaro chevhavha, inoderedza kuvhurika kwekuvhara, inoderedza kupera, uye inovandudza Chigaro. hupenyu.Kuchera kunoderedzwa zvakanyanya, uye panguva imwe chete,iyo kaviri eccentric butterfly valve inogonawo kushandisa chigaro chesimbi chevhavha, iyo inovandudza kushandiswa kwevhavhavhavhavhavha munzvimbo yepamusoro yekupisa.Nekudaro, nekuti iyo chisimbiso musimboti inzvimbo yekuisa chisimbiso chimiro, ndiko kuti, chisimbiso chepamusoro che disc uye chigaro chevhavha chiri mumutsara wekubatana, uye iyo elastic deformation inokonzerwa ne disc extrusion yechigaro chevhavha inoburitsa chisimbiso, saka ane yakakwirira zvinodiwa nokuda rokuvhara chinzvimbo (kunyanya simbi Valve chigaro), yakaderera kumanikidzwa kutakura kugona, ndosaka netsika vanhu vanofunga kuti shavishavi mavharuvhu haamiri kudzvinyirirwa uye ane leakage hombe.
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, kureva kuti, mushure mechitatu eccentricity, chikamu chekuisa chisimbiso che disc hachiite. shanduko.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 chisimbiso chakashandurwa zvakanyanya, hachisisiri chinzvimbo chisimbiso, asi chisimbiso che torsion, ndiko kuti, hachivimbi neiyo elastic deformation yechigaro chevharuvhu, asi inovimba zvizere nekusangana. Kudzvinyirirwa kwepamusoro pechigaro chevharuvhu kuti uwane chisimbiso chekuisa chisimbiso, Naizvozvo, dambudziko rekudonha zero kwechigaro chesimbi valve rinogadziriswa mune imwe yakawa swoop, uye nekuti iyo yekubata kumeso kudzvanywa kwakaenzana nepakati kudzvanywa, kudzvanywa kwepamusoro uye kupisa kwakanyanya. kushorwa kunogadziriswawo nyore.
