Kune mhando dzakawanda uye dzakaoma mhando dzemavharuvhu, kunyanya kusanganisira gedhi mavharuvhu, globe mavharuvhu, throttle mavharuvhu, butterfly mavharuvhu, plug mavharuvhu, bhora mavharuvhu, emagetsi mavharuvhu, diaphragm mavharuvhu, cheki mavharuvhu, kuchengeteka mavharuvhu, kudzvinyirira kuderedza mavharuvhu, chiutsi misungo uye chimbichimbi kuvhara-kure mavharuvhu, etc. , iyo anowanzoshandiswa gedhi vharafu, globe vharafu, throttle vharafu, plug vharafu, butterfly vharafu, bhora vharafu, cheki vharafu, diaphragm vharafu.
1 Butterfly valve
Butterfly vharuvhu ndiko kuvhura nekuvhara basa re butterfly plate rinogona kupedzwa nekutenderera 90° kutenderedza akisi yakamisikidzwa mumutumbi wevharuvhu. Butterfly vharafu idiki muhukuru, yakareruka muhuremu uye iri nyore muchimiro, uye inongori nezvikamu zvishoma. Uye inongoda kutenderera 90 °; inogona kuvhurwa nekuvharwa nekukurumidza, uye kushanda kuri nyore. Kana shavishavi vharafu iri munzvimbo yakanyatsozaruka, ukobvu hweshavishavi ndiro ndiyo chete inopikisa apo svikiro rinoyerera nemuviri wevharuvhu, saka kudonha kwemhepo kunogadzirwa nevharuvhu kudiki kwazvo, saka ine zvirinani kuyerera kwekudzora maitiro. Butterfly valve yakakamurwa kuita elastic soft seal uye simbi yakaoma chisimbiso. Elastic sealing valve, mhete yekuisa chisimbiso inogona kuiswa pamuviri wevharuvhu kana kusungirirwa padivi pedhisiki, iine yakanaka yekuisa chisimbiso kuita, iyo inogona kushandiswa kupuruzira, yepakati vacuum mapaipi uye corrosive media. Mavharuvhu ane zvisimbiso zvesimbi kazhinji ane hupenyu hwakareba kupfuura aya ane elastic seal, asi zvakaoma kuwana chisimbiso chakazara. Iwo anowanzo shandiswa muzviitiko zvine shanduko huru mukuyerera uye kudonhedza kudonhedza uye inoda kuita kwakanaka kwekupuruzira. Metal seals inogona kuenderana nepamusoro tembiricha yekushanda, nepo elastic seals ine hurema hwekuganhurwa netembiricha.
2Gedhi vharafu
Varuvhu yegedhi inoreva vharuvhu ine muviri wekuvhura nekuvhara (vharuvhu ndiro) inofambiswa nedzinde revharuvhu uye inofamba ichikwira nekudzika ichitevedza nzvimbo yakavharika yechigaro chevharuvhu, inokwanisa kubatanidza kana kucheka nzira yemvura. Kuenzaniswa neglobe valve, gedhi vharafu ine kushanda kwekuvhara zvirinani, kushomeka kwemvura, kushomeka kwekuedza kuvhura nekuvhara, uye ine kumwe kugadzirisa kuita. Ndiyo imwe yeanonyanya kushandiswa block valves. Izvo zvisingabatsiri ndezvokuti ukuru hukuru, chimiro chakanyanya kuoma kupfuura chevhavha yepasi, nzvimbo yekuisa chisimbiso iri nyore kupfeka, uye haisi nyore kuchengetedza. Kazhinji, haina kukodzera kupuruzira. Zvinoenderana nechinzvimbo chetambo pahunde yevharuvhu yegedhi, yakakamurwa kuita mhando mbiri: yakavhurika tsvimbo yemhando uye yakasviba tsvimbo. Zvinoenderana nehunhu hwegedhi, inogona kukamurwa kuita mhando mbiri: wedge mhando uye parallel mhando.
3 Tarisa vharafu
Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhaivhainogona kudzivirira kuyerera kwemvura. Ivhavhavhavhavha yevhavhavha yecheki inovhurwa pasi pechiito chekumanikidza kwemvura, uye mvura inoyerera ichibva kudivi rekupinza kuenda kudivi rekubuda. Kana kudzvinyirirwa kudivi rekupinza kwakadzikira pane kudivi rekubuda, vharafu yevharuvhu inovhara yega pasi pekuita kweiyo fluid pressure musiyano, giravhiti rayo uye zvimwe zvinhu kudzivirira mvura kuti isayerere kumashure. Zvinoenderana nechimiro, inogona kukamurwa kuita yekusimudza cheki vharafu uye swing cheki vharafu. Iyo yekusimudza mhando ine kuita kurinani kwekuvhara uye hombe yemvura inodzivirira pane inoswing mhando. Nokuda kwekusveta kwepombi yepombi yepombi, valve yepasi inofanira kusarudzwa. Basa rayo nderekuzadza pombi inopinza yepombi nemvura isati yatanga pombi; chengetedza pombi inopinza uye muviri wepombi uzere nemvura mushure mekunge pombi yamiswa, kuitira kugadzirira kutanga zvakare. Ivhavha yepasi inowanzoiswa chete papombi yakatwasuka yepombi inopinza, uye yepakati inoyerera kubva pasi ichienda kumusoro.
4 Globe valve
Ivhavharuvhu ivharuvhu yakavharika yakadzika, uye nhengo yekuvhura nekuvhara (vharuvhu) inofambiswa nedzinde revharuvhu kuti ifambe ichikwira nekudzika pamwe neakisi yechigaro chevharuvhu (sealing surface). Inofananidzwa nevhavha yegedhi, ine maitiro akanaka ekugadzirisa, kusasimba kwekuisa chisimbiso, chimiro chiri nyore, kugadzira uye kugadzirisa zviri nyore, kupikisa kukuru kwemvura uye mutengo wakaderera.
5 Bhora vharafu
Chikamu chekuvhura nekuvhara chevharuvhu ibhora rine denderedzwa kuburikidza neburi, uye bhora rinotenderera nedzinde revharuvhu kuti rione kuvhurwa nekuvhara kwevharuvhu. Ivhavhavha yebhora ine chimiro chakareruka, kukurumidza kushandura, kushanda kwakakodzera, hukuru hudiki, huremu huremu, zvishoma zvikamu, zviduku zvekudzivirira kwemvura, kushanda zvakanaka kwekuvhara uye kugadzirisa zviri nyore.
6 Throttle valve
Chimiro chevhavhavhavha inongofanana neiyo yevhavhavhavha kunze kwevhavha disc. Ivhavha disc inhengo ye throttling, uye maumbirwo akasiyana ane maitiro akasiyana. Iyo dhayamita yechigaro chevhavha haifaniri kunge yakakura, nokuti kureba kwekuvhura kuduku. Iyo yepakati yekuyerera mwero inowedzera, saka Inomhanyisa kukukurwa kwevhavha disc. Iyo throttle valve ine zviyero zviduku, uremu huremu uye maitiro akanaka ekugadzirisa, asi kugadzirisa kururamisa hakusi kwakakwirira.
7 Plug valve
Ivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharu inoshandisa plug body ineburi neburi sechikamu chinovhura nekuvhara,uye muviri weplug unotenderera nedzinde revharuvhu kuona kuvhurwa nekuvhara kwevharuvhu. Iyo plug valve ine zvakanakira chimiro chakareruka, kukurumidza kushandura, kushanda kwakaringana, kushomeka kwemvura inodzivirira, mashoma mashoma uye huremu huremu. Kune akatwasuka-kuburikidza, matatu-nzira uye mana-nzira plug mavharuvhu. Iyo yakatwasuka-kuburikidza nevhavhavhavha inoshandiswa kucheka svikiro, uye nzira nhatu-nenzira ina-mavharuvhu evhavha anoshandiswa kushandura nzira yepakati kana kupatsanura yepakati.
8 Diaphragm valve
Chikamu chekuvhura nekuvhara chevhavhavhavhavhavhavhavhavhavhavhavhavhavharuvharubha dhayaphragm,inoiswa sandwich pakati pemuviri wevharuvhu nevhavhavhavha. Chikamu chepakati chinobudikira chediaphragm chinogadzikwa patsinde yevharuvhu, uye muviri wevharuvhu wakaiswa rubber. Sezvo svikiro risingapindi mukati memukati wevhavhavhavha yevhavha, hunde yevharuvhu haidi bhokisi rekuisa. Iyo diaphragm valve ine chimiro chakareruka, kuita kwakanaka kwekuvhara, kugadzirisa kuri nyore uye kushomeka kwemvura. Diaphragm mavharuvhu akakamurwa kuva weir mhando, yakatwasuka-kuburikidza nemhando, kurudyi-kona mhando uye yakananga-kuyerera mhando.
