Kunzwisisa mutsauko uripo pakati peMavharuvhu eVenturiuyemavharuvhu eshavishaviZvakakosha pakusarudza mhinduro chaiyo yekudzora kuyerera kwemvura. Gwaro iri rinoenzanisa maumbirwo aro, mashandisirwo aro, mitengo, nezvimwewo.
Chii chinonzi Venturi Valve
A Vharuvhu yeVenturimudziyo unochengetedza kuyerera kwemhepo nemazvo wakagadzirirwa kuchengetedza kuyerera kwemhepo nguva dzose kana kuti mwero wemvura uchishandisa Venturi effect. Une huro yakatetepa inokurumidza kuyerera kwemvura uku ichideredza kumanikidzwa, zvichiita kuti pave nekudzora kwakarurama pasina kufamba kwezvikamu.
Chii chinonzi Butterfly Valve
A vharuvhu yeshavishaviivharuvhu inotenderera ine denderedzwa remakotara ine dhisiki rakatenderera rakaiswa pashaft inotenderera. Inodzora kuyerera kwemvura nekuisa dhisiki yakatwasuka (yakavharwa) kana kuti yakabatana (yakavhurika) kune medium. Iri nyore, haidhuri, uye yakakodzera kushandiswa nekukurumidza.
Chimiro & Nheyo yeKushanda
Vharuvhu yeVenturi
- Maumbirwo:Chubhu yakatetepa ine huro yakamanikana, nzvimbo dzekumanikidza, uye isina zvinhu zvinofamba.
- Nheyo:Anoshandisa musimboti waBernoulli—mvura inokurumidza kubuda muhuro, zvichiita kuti kumanikidzwa kudonhedzwe kuti kuyerera kweropa kudzore.
Vharuvhu yeBhatafurayi
- Maumbirwo:Muviri wakatenderera, dhisiki rinotenderera, mubato, uye actuator (inoshandiswa nemaoko kana otomatiki).
- Nheyo:Kutenderera kwedhisiki kunogadzirisa kuyerera; kutendeuka kwe90° kunovhura kana kuvhara vharuvhu zvizere.
Hunhu hweKudzora
| Chinhu | Vharuvhu yeVenturi | Vharuvhu yeBhatafurayi |
| Kunyatsojeka | Yakakwira (inoyerera nguva dzose) | Zviri pakati nepakati (zvinobatidzwa/zvisina kuvharwa kana kuti zvinotarisirwa) |
| Kukurumidza Kupindura | Kusashanda (hapana chikonzero chinodiwa) | Kukurumidza (kushanda nekukurumidza kwekota yekutendeuka) |
| Kuderera kweDzvinyiriro | Zvakaderera | Yakakwira (nekuda kwekuvharika kwedhisiki) |
Maitiro Ekushandisa
Vharuvhu yeVenturi
- Marabhoritari (magirazi emoto, makamuri ekuchenesa).
- Masisitimu eHVAC anoda kuti mhepo ifambe zvakanaka.
- Kuyerwa kwemakemikari nemwero chaiyo wekuyerera kwemvura.
Vharuvhu yeBhatafurayi
- Nzvimbo dzekuchenesa mvura.
- Mapaipi makuru (mafuta, gasi, mvura).
- Maitiro emaindasitiri anoda kuvharwa nekukurumidza.
Mari Yekugadzirisa
- Vharuvhu yeVenturi:Kugadziriswa kushoma (hapana zvikamu zvinofamba). Chinyorwa chepamusoro chepakutangamutengonekuda kwehunyanzvi hwekugadzira zvinhu nemazvo.
- Vharuvhu yeBhatafurayi:Mutengo unodhura usati watanga. Zvingada kuti pave nekutsiviwa kwemadhisiki/zvisimbiso nguva nenguva.
Nzvimbo yekuisa
- Vharuvhu yeVenturi:Dhizaini diki yemutsetse, inokodzera munzvimbo dzakamanikana.
- Vharuvhu yeBhatafurayi:Inoda nzvimbo yekutenderedza madhisiki; yakakura zvikuru kana yakakura.
Vagadziri Vepamusoro muChina
China ine vatungamiriri vakuruvagadziriyemavharuvhu ese ari maviri:
- Mavharuvhu eVenturi:ABC Flow Tech, Shanghai Valve Solutions.
- Mavharuvhu eBhatafurayi:Zhejiang Danfoss Valve, China Yuanda Valve Group,Mugadziri weVharuvhu yeNSW
Tafura Yekupfupisa Yekuenzanisa
| Chikamu | Vharuvhu yeVenturi | Vharuvhu yeBhatafurayi |
| Dhizaini | Hapana zvinhu zvinofamba, huro yadzikira | Dhisiki rinotenderera, muviri mudiki |
| Kunyatsojeka | Yakakwirira | Zviri pakati nepakati |
| Mutengo | Mutengo wekutanga wakakwira | Mutengo wekutanga wakaderera |
| Kugadzirisa | Zvishoma | Kuongororwa kwedhisiki/chisimbiso chenguva nenguva |
| Zvakanakira | Kudzora kuyerera kwemazvo | Kuvharwa nekukurumidza, mapaipi makuru |
Mhedziso
Mavharuvhu eVenturikugona pakuita zvinhu nemazvo uye kugadzirisa zvinhu zvishoma, ukuwomavharuvhu eshavishaviinopa mukana wekutengesa zvinhu zvakachipa uye kushanda nekukurumidza. Pakusarudza, funga nezvezvinodiwa pakufamba kwemvura, bhajeti, nenzvimbo. Kuti uwane makwikwi emakwikwi.mitengo, ongororavagadziri muChinanyanzvi mumavharuvhu emaindasitiri.
