Kutshanje, umzi-mveliso uvelisa inqwaba yeesangqaivalvu yeflap, ivalvu ejikelezayo yivalvu yendlela enye, esetyenziswa kakhulu kubunjineli be-hydraulic nakwezinye iindawo.

Xa ucango luvaliwe, iphaneli yocango igcinwa ivaliwe ngenxa yobunzima bayo okanye ubunzima bayo. Xa amanzi ephuma kwelinye icala locango ukuya kwelinye, amandla amanzi atyhala ipleyiti yocango yocango, ebangela ukuba ijikeleze umgodi wocango ize ivuleke, ngaloo ndlela ivumela amanzi ukuba adlule kakuhle. Xa ukuhamba kwamanzi kunendlela yokuhamba ngokubuyela umva, phantsi kwesenzo soxinzelelo lwamanzi kunye nobunzima bocango ngokwalo, ucango luya kuvala ngokuzenzekelayo ukuthintela ukuhamba kwamanzi ngokubuyela umva, ukuze kufezekiswe umsebenzi wokuhamba kwamanzi ngendlela enye.

Umzekelo, ekuphumeni kwezinye iipayipi zokukhupha amanzi, ucango luvulwa ngexesha lokukhupha amanzi okuqhelekileyo, kwaye ukuba kukho umkhwa wokuchitha amanzi angaphandle emva kokukhupha amanzi, ucango luya kuvalwa ukuthintela ukuchitheka kwamanzi okungasemva.

Kwinkqubo yokunkcenkceshela, ivalvu ejikelezayo ingafakwa kwindawo yokuphuma komjelo wokunkcenkceshela. Xa kufuneka ukunkcenkceshela, amanzi aphuma kumjelo aze atyhale ucango lwempompo luvuleke, nto leyo evumela amanzi ukuba angene emasimini. Emva kokuba ukunkcenkceshela kugqityiwe, ucango luyavalwa ukuthintela ukulahleka kwamanzi kumjelo kunye nenkunkuma yangaphandle engena kumjelo.

Kwisikhululo sokumpompa amanzi esixekweni, xa isikhululo sokumpompa amanzi siphuma, ucango olujikelezileyo luyavulwa, ukuze amanzi emvula akhutshwe kakuhle emilanjeni nasemachibini; Emva kokuphela kokukhupha amanzi, kunokuthintela ngokufanelekileyo amanzi echibi lomlambo ukuba abuyele kwisikhululo sokumpompa amanzi, ukuze kuthintelwe ukuba isikhululo sokumpompa sigcwale. Ukongeza, kwindawo yokuphuma komzila wokuphalaza kwamanye amachibi, ukuba kukho imfuneko yokuthintela ukuvuza kwamanzi kwakhona, ivalvu ejikelezileyo inokudlala indima entle ekulawuleni ukuhamba kwamanzi ngendlela enye.

Iivalvu zezicelo ezifanayo ziquka iValve engabuyiyo. IValve yeJinbin yenza ngokwezifiso uthotho lweevalvu ezifanaivalvu yesango, yenziwe ngentsimbi eshayinayoisango le-penstock, ivalvu yebhabhathane engaqhelekanga ephindwe kabini, i-air damper enobubanzi obukhulu, ivalvu yokujonga amanzi, ivalvu yokukhupha amanzi, njl. Ukuba unayo nayiphi na imfuno enxulumene noko, nceda ushiye umyalezo apha ngezantsi. Uza kufumana impendulo kwiiyure ezingama-24 kwaye ujonge phambili ekusebenzeni nawe.
