Maitiro Ekuongorora uye Kuongorora Valve
Semudziyo unokosha wekudzora mvura, mavharuvhu anoshandiswa zvakanyanya munzvimbo dzakawanda dzakadai semafuta, indasitiri yemakemikari, uye magetsi. Mugadziri weVaruvhu weNSW achaongorora zvinhu zvikuru zvekuyedzwa kwevharuvhuuye zvinoenderana navomitemo yekuongorora.
Tsanangudzo yeVharufu
Mavharuvhu zvishandiso zvinoshandiswa kudzora kuyerera kwemvura, kumanikidzwa, tembiricha nezvimwe zvinhu zvemvura, uye zvinoshandiswa zvakanyanya mumidziyo yemumaindasitiri, yemumba, neyemumba. Zvichienderana nemashandisirwo akasiyana uye mabasa, mavharuvhu anogona kukamurwa kuita mhando dzakasiyana, dzakadai se:
Vharuvhu yeGedhi: Vhura uye vhara nzira yemvura nekusimudza ndiro yegedhi, yakakodzera nguva dzakavhurika kana dzakavharika.
Vharuvhu yeBhora: Dzora kuyerera kwemvura nekutenderedza bhora, nerubatsiro rwekuvhara zvakanaka, chimiro chiri nyore, uye kushanda kuri nyore.
Vharuvhu Yepasie: Dzora kuyerera kwemvura nekutenderedza tsinde yevharuvhu kuti dhisiki revharuvhu rifambe richikwira nekudzika, nokudaro richichinja saizi yechiteshi chevharuvhu, chakakodzera kudzora nekugura mvura.
Vharuvhu yeBhatafurayi: Dzora kuyerera kwemvura nekutenderedza dhisiki (butterfly plate), inowanzoshandiswa kudzora mvura mumapaipi makuru.
Vharuvhu Yekutarisa: Inoshandiswa kudzivirira kudzoka kwemvura, inowanzoiswa panobuda pombi kana mupombi yemvura.
Vharuvhu Yekuchengetedza: Kana kumanikidzwa kuri musystem kukadarika kukosha kwakatarwa, kunovhurika otomatiki kudzivirira kumanikidzwa kwakanyanya, kunonyanya kushandiswa kuchengetedza kuchengetedzeka kwemidziyo nemasisitimu.
Zvinhu zvikuru zveValve Check
Kuongororwa kwemavharuvhu kwakakosha kuti ive nechokwadi chekuti akachengeteka uye akavimbika munzvimbo dzakasiyana siyana dzekushandisa. Izvi zvinotevera ndizvo zvinhu zvikuru zvekuongorora mavharuvhu pamwe chete nezvinodiwa uye nzira dzekuongorora.
