Inzuzo yemveliso: 1. Izinto ezigqwesileyo zokutywinwa kakuhle. 2. Ufakelo olulula ukumelana nokuqukuqela okuncinci. 3. Umsebenzi wokonga umbane weinjini yomoya.
Iivalve zesango ziyinxalenye ebalulekileyo yamashishini ahlukeneyo, apho ulawulo lokuhamba kwamanzi lubalulekile. Ezi zivalo zibonelela ngendlela yokuvula ngokupheleleyo okanye ukuvala ukuhamba kwamanzi, ngaloo ndlela ulawula ukuhamba kunye nokulawula uxinzelelo ngaphakathi kwenkqubo. Iivalvu zesango zisetyenziswa kakhulu kwimibhobho ethutha ulwelo olunjengamanzi neoyile kwakunye neegesi.
Iivalvu zesango le-NRSzithiywe ngoyilo lwazo, olubandakanya umqobo onjengesango ohamba phezulu naphantsi ukulawula ukuhamba. Amasango anxusene kwicala lokuhamba kolwelo ayaphakanyiswa ukuvumela ukudlula kolwelo okanye ukuthotywa ukunqanda ukudlula kolwelo. Olu yilo olulula kodwa olusebenzayo luvumela ivalve yesango ukuba ilawule ngokufanelekileyo ukuhamba kwaye ivale ngokupheleleyo inkqubo xa kufuneka.
Inzuzo ephawulekayo yeevalvu zesango kukuhla koxinzelelo oluncinci. Xa ivuleke ngokupheleleyo, iivalvu zesango zibonelela ngendlela ethe tye yokuhamba kwamanzi, evumela ukuhamba okuphezulu kunye nokuhla koxinzelelo oluphantsi. Ukongezelela, iivalve zesango ziyaziwa ngokuba namandla okutywina okuqinileyo, ukuqinisekisa ukuba akukho kuvuza okwenzekayo xa ivalve ivalwe ngokupheleleyo. Oku kuzenza zilungele usetyenziso olufuna ukusebenza okungavuziyo.
Irabha ehleli iivalvu zeSangozisetyenziswa kwiintlobo ngeentlobo zamashishini, kubandakanywa ioli kunye negesi, unyango lwamanzi, iikhemikhali kunye nezityalo zamandla. Kwishishini le-oyile negesi, iivalvu zesango zisetyenziselwa ukulawula ukuhamba kwe-oyile ekrwada kunye negesi yendalo ngaphakathi kwemibhobho. Amaziko okucoca amanzi asebenzisa iivalvu zesango ukulawula ukuhamba kwamanzi ngeenkqubo ezahlukeneyo zokucocwa. Iivalvu zesango zikwasetyenziswa ngokuqhelekileyo kwizixhobo zombane, ezivumela ulawulo lokuhamba komphunga okanye isisipholisi kwiinkqubo zomoya.
Nangona iivalve zesango zibonelela ngeenzuzo ezininzi, nazo zinemida ethile. Enye into engalunganga enkulu kukuba zisebenza ngokucothayo xa kuthelekiswa nezinye iindidi zeevalvu. Iivalve zesango zifuna ukujika okuningana kwevili lesandla okanye i-actuator ukuze ivuleke ngokupheleleyo okanye ivale, enokuchitha ixesha elininzi. Ukongeza, iivalve zesango zichaphazeleka kumonakalo ngenxa yokuqokelela inkunkuma okanye izinto eziqinileyo kwindlela yokuhamba, ebangela ukuba isango livaleke okanye libambeke.
Isishwankathelo, iivalve zesango ziyinxalenye ebalulekileyo yeenkqubo zoshishino ezifuna ulawulo oluchanekileyo lokuhamba kwamanzi. Ubunakho bokutywina obuthembekileyo kunye nokuhla koxinzelelo oluncinci kuyenza ibaluleke kakhulu kumashishini ahlukeneyo. Nangona zinemida ethile, iivalve zesango ziyaqhubeka zisetyenziswa ngokubanzi ngenxa yokusebenza kakuhle kunye nokusebenza kakuhle ekulawuleni ukuhamba.
