2.5 Vharuvhu yepuragi

Vharuvhu yeplagi ivharuvhu inoshandisa muviri weplagi une gomba rinopinda sechikamu chekuvhura nekuvhara, uye muviri weplagi unotenderera netsinde yevharuvhu kuti ivhurike nekuvhara. Vharuvhu yeplagi ine chimiro chiri nyore, kuvhura nekuvhara nekukurumidza, kushanda kuri nyore, kusapindirana kwemvura kudiki, zvikamu zvishoma uye huremu hwakareruka. Mavharuvhu eplagi anowanikwa mumhando dzakatwasuka, nhatu uye ina. Vharuvhu yeplagi yakatwasuka inoshandiswa kucheka medium, uye mavharuvhu eplagi ane nzira nhatu uye ina anoshandiswa kushandura divi remedium kana kutsausa medium.

2.6Vharuvhu yeshavishavi

Vharuvhu yeshavishavi iplate yeshavishavi inotenderera 90° yakatenderedza axis yakagadzika mumuviri wevharuvhu kuti ipedzise basa rekuvhura nekuvhara. Mavharuvhu eshavishavi madiki, akareruka uye ari nyore kugadzira, ane zvikamu zvishoma chete.

Uye inogona kuvhurwa nekuvharwa nekukurumidza nekungotenderera 90°, izvo zviri nyore kushanda. Kana vharuvhu remapuruguru riri munzvimbo yakavhurika zvizere, ukobvu hwepuratifomu remapuruguru ndiyo chete inodzivisa kana medium ichiyerera nemumuviri wevharuvhu. Nokudaro, kudonha kwekumanikidzwa kunokonzerwa nevharuvhu kudiki kwazvo, saka ine hunhu hwakanaka hwekudzora kuyerera. Mavharuvhu emapuruguru akakamurwa kuita mhando mbiri dzekuvhara: elastic soft seal uye metal hard seal. Elastic sealing valve, sealing ring inogona kuiswa mumuviri wevharuvhu kana kusungirirwa kumucheto kwepuratifomu remapuruguru. Ine sealing performance yakanaka uye inogona kushandiswa pakupwanya, mapaipi evacuum ari pakati nepakati uye corrosive media. Mavharuvhu ane simbi seals anowanzo kuve nehupenyu hwakareba hwekushanda kupfuura mavharuvhu ane elastic seals, asi zvakaoma kuwana sealing yakakwana. Anowanzo shandiswa mumamiriro ezvinhu apo kudonha kwekuyerera nekumanikidzwa kunochinja zvakanyanya uye kushanda kwakanaka kwekupwanya kunoda. Metal seals inogona kugadzirisa tembiricha yepamusoro, nepo elastic seals ine dambudziko rekuganhurirwa netembiricha.

2.7Vharuvhu yekutarisa

Vharuvhu rekuongorora ivharuvhu rinogona kudzivirira kuyerera kwemvura kubva pakudzokera shure. Dhisiki yevharuvhu rekuongorora inovhurwa nekumanikidzwa kwemvura, uye mvura inoyerera kubva parutivi rwekupinda kuenda kudivi rekubuda. Kana kumanikidzwa kuri parutivi rwekupinda kwakaderera pane parutivi rwekubuda, vharuvhu rinovhara roga pasi pekusiyana kwekumanikidzwa kwemvura, simba rayo guruva nezvimwe zvinhu zvinodzivirira mvura kuti isadzokere shure. Zvichienderana nechimiro chechimiro, inogona kukamurwa kuita vharuvhu rekuongorora rinosimudza nevharuvhu rekuongorora rinotenderera. Rudzi rwekusimudza rune seal iri nani uye runodzivirira mvura kupfuura rudzi rwekusvetuka. Kune pombi yekukweva pombi yekukweva pombi, vharuvhu repasi rinofanira kushandiswa. Basa rayo nderekuzadza pombi yekukweva pombi nemvura usati watanga pombi; mushure mekumisa pombi, chengeta pombi yekukweva nemuviri wepombi yakazadzwa nemvura uchigadzirira kutanga zvakare. Vharuvhu repasi rinowanzoiswa papombi yakamira panzvimbo yekukweva pombi, uye medium inoyerera kubva pasi kuenda kumusoro.

2.8Vharuvhu yedhayafura

Chikamu chinovhura nekuvhara chevharuvhu yediaphragm idhayagramu yerabha, iyo yakasungirirwa pakati pemuviri wevharuvhu nechifukidziro chevharuvhu.

Chikamu chepakati che diaphragm chakasungirirwa pamudzi wevharuvhu, uye muviri wevharuvhu wakaputirwa nerabha. Sezvo nzvimbo yacho isingapindi mukati memukati mevharuvhu, mudzi wevharuvhu haudi bhokisi rekuputira. Vharuvhu ye diaphragm ine chimiro chiri nyore, inoshanda zvakanaka pakuvharira, iri nyore kugadzirisa, uye inodzivirira mvura shoma. Mavharuvhu e diaphragm akakamurwa kuita mhando ye weir, mhando yakatwasuka, mhando ye right-angle uye mhando ye direct-flow.

3. Mirayiridzo yekusarudza mavharuvhu inowanzo shandiswa
