Ivhavha yegedhi inogona kushandiswa kune nhamba yakawanda yemvura.Mavharuvhu emagedhi akakodzera pasi pemamiriro ezvinhu anotevera ekushanda: Mvura inonwiwa, mvura yetsvina uye zvinwiwa zvisina kwazvakarerekera: tembiricha iri pakati pe -20 ne +80 ℃, yakakura 5 m/s flow velocity uye inosvika 16 bar differential pressure.
Kushandiswa: Gedhi revhavha yechisimbiso yakapfava inowana chisimbiso inowana chisimbiso chekushanda, uchishandisa simba rinouya kubva kune elastil sluice board, dzima svikiro, uko kudzvanywa kwekushanda kuri ≤ 1 MPa, tembiricha yekushanda iri ≤ 8 ° C.Zvinoshandiswa zvakanyanya mukugadzira, edibles, mushonga, kemikari simba, kuisa uye dhizaini indasitiri yemvura, etc. gadzirisa mvura mupombi uye pombi inozviitawo mumidziyo.
Ductile iron resilient yakagara gedhi mavharuvhu akagadzirwa kuti ape yakavimbika uye inogara kwenguva refu sevhisi mumvura yekugovera uye kugovera masisitimu.Aya mavharuvhu anogadzirwa zvinoenderana neBritish Standard BS5163 uye akakodzera kushandiswa mune zvese zviri pamusoro-pasi uye pasi pevhu.
Muviri wevhavha wakagadzirwa ne ductile iron, inova chinhu chakasimba uye chakasimba chinogona kumirisana nekumanikidza kwakanyanya uye tembiricha.Iyo valve inewo chigaro chinogadzirisa, chinopa chisimbiso chakasimba uye chinodzivirira kubuda.Chigaro chinogadzika chinogadzirwa neEPDM kana NBR rabha, iyo inopesana nekuora uye kurwisa kwemakemikari.
Gedhi revhavha rakagadzirirwa kufamba zvakanaka uye nyore, richipa yakaderera kushanda torque uye kuderedza dambudziko rekukuvara kwevhavha.Gedhi rakaputirwawo ne epoxy kupa imwe dziviriro kubva mukuora.
Ivhavha inoshandiswa uchishandisa handwheel kana gearbox, iyo inobvumira kudzora nyore uye kwakanyatsojeka kwekuyerera kwemvura.Ivhavha inogona kuiswa mune chero nzvimbo, ichiita kuti ive yakakodzera kushandiswa mune zvakasiyana-siyana zvekushandisa.
Pakazara, ductile iron resilient yakagara gedhi mavharuvhu ndeye yakavimbika uye inodhura-inoshanda mhinduro yekugovera mvura uye kugovera masisitimu.Izvo zviri nyore kuisa, kushanda, uye kuchengetedza, uye kupa sevhisi inogara kwenguva refu ine kushoma kuderera.
