Varuvhu yedu inogona kugadzirwa nemhando dzakasiyana dzezvinhu, inogadzirwa neyakajairwa chiyero chepasi rose uye chiyero chenyika zvinoenderana nezvaunoda.
Muviri wevharuvhu uye zvikamu zvemukati zvinogadzirwa neCNC muchina kuvimbisa iko kurongeka kwekugadzirwa kwevharuvhu.Iyo epoxy coating body ine chitarisiko chakanaka.
Muviri wevharuvhu wakagadzirwa neQT450 kana WCB, uye chimiro chayo chemakemikari uye michina inoenderana nezvinodiwa zvemitemo yenyika.Zvinyorwa zvinyorwa zviripo.
Kune zvisimbiso zverabha zvakapfava uye simbi-simbi yakaoma zvisimbiso kusarudza kubva.Zvikamu zvakadai semahwendefa evhavha zvinogonawo kusarudzwa maererano nemamiriro ekushanda.
Chigaro chevharuvhu chakashongedzwa nesimbi isina tsvina, iyo inonyanya kupfeka uye ine hupenyu hurefu hwebasa.
Iyo shaft yevhavha inotsigirwa ne-self-lubricating sleeve bearings, iyo inogona kuderedza kukweshera uye torque inogadzirwa panguva yekutapurirana kwevhavha shaft.
Mavharuvhu ebutterfly akafanana nemavharuvhu ebhora asi ane zvimwe zvakanakira.Kana dzakaitwa pneumatically, dzinovhura nekuvharika nekukurumidza.Madhisiki akareruka pane mabhora, uye vharafu inoda kushoma kwechimiro chetsigiro pane vharafu yebhora yedhayamita inofananidzwa.Butterfly mavharuvhu akanyatsojeka, izvo zvinovapa mukana mukushanda kwemaindasitiri.Izvo zvinovimbika zvakanyanya uye zvinoda zvishoma kugadzirisa.
Nyore uye nekukurumidza kuvhura / kuvhara nesimba shoma.Iine kushomeka kwemvura uye inogona kushandiswa kazhinji
Chimiro chacho chiri nyore, ukuru hudiki, uye hukuru hwechiso nechiso hupfupi, hwakakodzera mavharuvhu makuru-diameter.
Iyo yekuisa chisimbiso inowanzo gadzirwa nerabha kana plastiki.Naizvozvo, shavishavi vharuvhu ine yakanaka yekuisa chisimbiso kuita pasi pekumanikidzwa kwakaderera.
Flanged rubber lined butterfly mavharuvhu anoshandiswa zvakanyanya mukutakura zvinwiwa nemagasi (kusanganisira steam) mumaindasitiri akasiyana.
Mapaipi, kunyanya ayo anoshandiswa kune zvinokuvadza zvakanyanya senge hydrofluoric acid, phosphoric acid, chlorine, alkali yakasimba, aqua regia uye
4-level reload elastic seal inovimbisa zero kuvuza mukati uye kunze kwevharuvhu.
Ichi chigadzirwa chinoshandiswa kune mvura uye dhizaini system mumvura yepombi, sewage, chivako, makemikari etc. maindasitiri, anowanzoshandiswa seyakavhurika-yekuvhara michina.
Mavharuvhu ebutterfly akafanana nemavharuvhu ebhora asi ane zvimwe zvakanakira.Iwo akavhurika uye akavharika nekukurumidza zvakanyanya kana actuated pneumatically.Iyo dhisiki yakareruka kupfuura bhora, uye mavharuvhu anoda kushoma kwechimiro chetsigiro pane bhora vharafu yedhayamita inofananidzwa.Butterfly mavharuvhu akanyatsojeka, izvo zvinoita kuti zvive zvinobatsira mukushanda kwemaindasitiri.Izvo zvakavimbika uye zvinoda kuchengetwa kushoma.
