Valavu yambiri, monga momwe dzina limanenera, ndi valavu yomwe ingayankhe pazizindikiro zingapo zosiyana. Ndiwopangidwa makamaka ndi thupi la valavu, valavu yobwerera, ndipo madoko awiri olamulira. Pamene zovuta zomwe zalandiridwa ndi madoko awiriwo ndizosiyana, valavu yolimbayo isamuke, posintha njira yolowera madzi kapena kuwongolera kuchuluka kwa madzimadzi.

Mu mavuvu aanthu awiri, kuphatikiza kosiyanasiyana kwa zizindikiro zovuta kumathandizira molondola madzimadzi. Mwachitsanzo, dokotala wina akalandira chizindikiro chambiri ndipo winayo amalandila chizindikiro chotsika kwambiri, valavu yotsika ya valavu imasunthira kumapeto kwenikweni, potsatira kutsika kwa madzimadzi. Njira yoyankha yosinthika iyi imathandizira mavesi opanikizika amwambo kuti achite mbali yofunika kwambiri pamachitidwe ovuta kuwongolera.

Chiyanjano chomveka cha valavu yolumikizirana nthawi zambiri imawonekera momwe imasinthira zotulutsa zosiyanasiyana malinga ndi zomwe amafunikira dongosolo. Njirayi imatsirizidwa makamaka ndi kuwongolera hydraulic mtundu, kuphatikizapo kuponderezana, kuphatikiza kutumiza ndi kuchitapo kanthu. Pamapulogalamu othandiza, ubale womveka uwu ukhoza kulamulidwa molondola kudzera mu gawo la magetsi (Ecu).

1. Kukakamiza kumvetsetsa: makina owunikira omwe ali ndi nthawi yeniyeni kudzera mwa sensa yovuta. Mwachitsanzo, dongosololi likamafunika kupanikizika kwambiri kapena kutsika kwambiri, ma sensa yotumiza amatembenuza kufunikira kwake kukhala chizindikiro chamagetsi ndikufalitsa gawo lowongolera.

2. Kusanja: Mukalandira kukakamiza komwe kumapangitsa kuti chizindikirocho chizikhala chikuwonetsa chizindikiro malinga ndi chiyanjano choyenera ndikupanga lingaliro lotha kusintha zovuta.
