Gedhi vharafu uye butterfly valveese ari maviri anoita basa rekuchinja uye kudzora kuyerera mukushandiswa kwepombi.Ehezve, kuchine nzira mukusarudzwa kwemavharuvhu e butterfly uye mavharuvhu egedhi.
Munetwork yekupa mvura, kuti kuderedze kudzika kweivhu rekuvhara kwepombi, kazhinji mapaipi makuru edhayamita anebutterfly mavharuvhu, iyo ine zvishoma zvishoma pakuvhara ivhu kudzika, uye edza kusarudza mavharuvhu emagedhi, asi mutengo wemavhavha emagedhi ezvinyorwa zvakafanana zvakakwirira kudarika zvevhavhavhavhavha.Kana iri mutsara wekuganhura we caliber, inofanirwa kutariswa pane imwe nyaya-ne-kesi hwaro.Kubva pamaonero ekushandiswa mumakore gumi apfuura, kukundikana kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha zwa vhuvhuvhu,nahone zwa fanela u dzhia zwine zwa vhathu vha tshi shumisa vhezheni vhevheru nga vhurereli.
Nezve mavharuvhu emagedhi Mumakore achangopfuura, vazhinji vanogadzira mavharuvhu epamba vakagadziramavharuvhu emagedhi akapfava.Kuenzaniswa neyechinyakare wedge-mhando kana parallel kaviri-plate gedhi mavharuvhu, iyi vharafu yegedhi ine zvinotevera maitiro:
* Muviri wevharuvhu uye bhoneti yevhavha yakavharwa-yakavharwa yegedhi inokandwa nenzira yakarurama yekukanda nzira, iyo inoumbwa panguva imwe chete, chaizvoizvo pasina kushandiswa kwemagetsi, uye haishandisi chisimbiso chemhangura yemhangura, iyo inochengetedza simbi isina-ferrous.
* Hapana gomba pazasi pevhavha yegedhi rakapfava, uye hapana slag inounganidzwa, uye kutadza kwegedhi kuvhura uye kuvhara kwakaderera.
* Iyo yakapfava chisimbiso rabha-yakaiswa valve ndiro ine yunifomu saizi uye yakasimba kuchinjana.
Naizvozvo, theyakapfava yekuvhara gedhi vharafuichava chimiro icho indasitiri yemvura inoda kutora.Parizvino, dhayamita yezvinyoro-yakavharwa gedhi mavharuvhu anogadzirwa muChina anosvika 1500mm, asi dhayamita yevazhinji vanogadzira iri pakati pe80-300mm.Chinhu chakakosha chevhavha yakapfava yekuvharisa gedhi ndiro rabha-lined valve plate, uye zvinodiwa zvehunyanzvi zverabha-lined valve plate zvakakwirira, izvo zvisiri izvo vanogadzira kunze kwenyika vanogona kuwana, uye zvinowanzotengwa nekuunganidzwa kubva kune vanogadzira vakavimbika. quality.
Iyo yemhangura nut block yemumba yakapfava yekuvharisa gedhi vharafu yakamisikidzwa pamusoro perabha-lined valve plate, yakafanana nechimiro chevhavha yegedhi.Nekuda kwekukweshana kunofambiswa kwe nut block, rubber lining yeplate yevharuvhu inopepetwa zviri nyore.Mune yakapfava yekuvharisa gedhi vharafu yeimwe kambani yekunze, iyo yemhangura nut block inomisikidzwa mugedhi rine rabha-line mutsara kuti riumbe rose, iro rinokunda kukanganisa kuri pamusoro, asi concentricity yekubatanidzwa kwebhoneti uye muviri wevharuvhu wakakwira zvakati. .
Nekudaro, pakuvhura nekuvhara iyoyakapfava yekuvhara gedhi vharafu, haifaniri kunge yakavharwa zvakanyanya, chero bedzi mvura inomisa mvura inowanikwa, kana zvisina kudaro hazvisi nyore kuzarura kana rubber lining inobviswa.Mugadziri wevharuvhu anoshandisa torque wrench kudzora dhigirii rekuvhara panguva yekuedzwa kwevhavhavha.Sevhavhavhavha yekambani yemvura, iyi nzira yekuvhura nekuvhara inofanirawo kutevedzerwa.
