Ezimbonini zasolwandle kanye nezasogwini lolwandle, ukusetshenziswa kwamavalvu ebhabhathane angangeni emanzini olwandle kubalulekile ukuqinisekisa ukusebenza okusebenzayo nokuthembekile kwezinhlelo nemishini ehlukahlukene. Lawa mavalvu akhethekile aklanyelwe ukumelana nezimo ezinzima zezindawo zamanzi olwandle, okwenza abe yizingxenye ezibalulekile ezinhlotsheni ezahlukene zokusebenza okuhlanganisa ukungena nokuphuma kwamanzi olwandle, izinhlelo ze-ballast, izinhlelo zamanzi okupholisa, nokuningi.

Amanzi olwandle agqwala kakhulu ngenxa yokuqukethwe kwawo okunosawoti omningi, okwenza amavalvu endabuko neminye imishini iwohloke ngokushesha. Ngakho-ke, ukusetshenziswa kwamavalvu ebhabhathane angangeni emanzini olwandle kubalulekile ekuvimbeleni ukugqwala nokuqinisekisa ukusebenza kwesikhathi eside nokuthembeka kwezinhlelo ezibalulekile ezindaweni zasolwandle nasogwini lolwandle.

Esinye sezici eziyinhloko zamavalvu ebhabhathane angangeni manzi olwandle ukwakhiwa kwawo kusetshenziswa izinto eziklanyelwe ngqo ukumelana nemiphumela yokugqwala kwamanzi olwandle. Lezi zinto ngokuvamile zifaka insimbi engagqwali yezinga eliphezulu, ithusi, noma ezinye izinhlobo ezimelana nokugqwala ezingamelana nezimo ezinzima zezindawo zamanzi anosawoti.

Ngaphezu kokwakhiwa okumelana nokugqwala, amavalvu ebhabhathane amelana namanzi olwandle aklanyelwe ukuhlinzeka ngokusebenza okuthembekile nokusebenza kahle ekusetshenzisweni kwasolwandle. Ukwakheka kwawo okuhlukile kwebhabhathane kuvumela ukusebenza okusheshayo nokulula, okwenza kube kuhle kakhulu ekusetshenzisweni okudinga ukuvulwa nokuvalwa njalo kwevalvu. Lo mklamo uphinde uvumele ukulawulwa okunembile kokugeleza, okwenza ivalvu yebhabhathane emelana namanzi olwandle ifanelekele izidingo ezahlukahlukene zokugeleza nokucindezela.

Ngaphezu kwalokho, ama-valve ebhabhathane angangeni emanzini olwandle avame ukuhlonyiswa ngobuchwepheshe obuthuthukisiwe bokuvala ukuqinisekisa ukusebenza kahle kokuvala ngisho nalapho kukhona amanzi olwandle agqwalayo. Lokhu kubalulekile ukuvimbela ukulahleka kwezinsiza ezibalulekile, njengamanzi olwandle asetshenziselwa ukupholisa noma ukuqinisa izindonga, nokugcina ubuqotho bezinhlelo ezibalulekile ezisetshenziswa olwandle nasogwini lolwandle.

Ukubaluleka kwamavalvu ebhabhathane amelana namanzi olwandle kusobala kakhulu ezinhlelweni zokungena nokukhipha amanzi olwandle. Lezi zinhlelo zibalulekile emisebenzini eyahlukahlukene yasolwandle kanye neyasogwini, okuhlanganisa ukupholisa izinjini nemishini emanzini olwandle, i-ballast yemikhumbi ukuqinisekisa ukuzinza, kanye nokuhlinzeka ngamanzi olwandle ezinqubweni ezahlukene zezimboni. Amavalvu ebhabhathane amelana namanzi olwandle adlala indima ebalulekile ekulawuleni ukugeleza kwamanzi olwandle kulezi zinhlelo, ukuqinisekisa ukusebenza kahle kanye nokuvimbela ingozi yokwehluleka okuhlobene nokugqwala.

Esinye isicelo esibalulekile sama-valve e-butterfly amelana namanzi olwandle uhlelo lwamanzi okupholisa lwemikhumbi nemishini yasogwini. Lezi zinhlelo zibalulekile ekuqedeni ukushisa okukhiqizwa yizinjini, imishini neminye imishini, futhi amanzi olwandle avame ukusetshenziswa njengendawo yokupholisa ngenxa yezakhiwo zawo ezicebile zokushisa. Ama-valve e-butterfly amelana namanzi olwandle asetshenziselwa ukulawula ukugeleza kwamanzi olwandle ngalezi zinhlelo zokupholisa, ukuqinisekisa ukudluliselwa kokushisa okuphumelelayo nokuvimbela ingozi yezinkinga ezihlobene nokugqwala ezingalimaza ukusebenza kwemishini ebalulekile.

Ngamafuphi, ukusetshenziswa kwamavalvu ebhabhathane amelana namanzi olwandle kubalulekile ekuqinisekiseni ukusebenza okuthembekile nokusebenza kahle kwezinhlelo ezibalulekile ezisetshenziswa olwandle nasogwini lolwandle. Ukwakhiwa kwawo okumelana nokugqwala, ukusebenza okuthembekile kanye nezakhiwo zokuvala kuyenza ibe yingxenye ebalulekile ezisetshenziswayo ezahlukahlukene, okuhlanganisa ukungena nokuphuma emanzini olwandle, izinhlelo zamanzi okupholisa, izinhlelo ze-ballast, nokuningi. Ngokukhetha ivalvu yebhabhathane emelana namanzi olwandle, imboni yasolwandle kanye nasogwini lolwandle ingaqinisekisa ukusebenza kwesikhathi eside kanye nobuqotho bezinhlelo zayo, ngisho nangaphansi kwezimo ezinzima nezigqwala zezindawo zamanzi olwandle.
