Kwihlabathi lokucima umlilo, isekhondi nganye ibalulekile. Ukuba nezixhobo ezithembekileyo kubalulekile ekuthinteleni ukulibaziseka nokuqinisekisa ukhuseleko lwabacimi-mlilo kunye noluntu. I-valve yokutshekisha yinto ebalulekileyo yezixhobo ezidlala indima ebalulekileyo kwinkqubo yokukhusela umlilo.
Ivalve yokukhangela sisixhobo esivumela ulwelo ukuba luhambe kwicala elinye kuphela. Isetyenziswa kakhulu kwiinkqubo zokukhusela umlilo ukukhusela umva okanye ukubuyisela umva. Ekucimeni umlilo, ii-valve zokuhlola ziqinisekisa ukuba amanzi okanye i-foam yokucima umlilo ihamba ngendlela efunwayo kwaye ayiphazamisi ukusebenza kakuhle kwenkqubo yokucima umlilo.
Ngexesha likaxakeka lomlilo, abacimi bomlilo baxhomekeke kumanzi avela kwi-hydrants kunye nemibhobho ukucima ngokukhawuleza amadangatye. Ngaphandle kwevalve yokutshekisha, unikezelo lwamanzi lunongcoliseka okanye lonakaliswe. Kwiimeko apho ii-hydrants ezininzi zomlilo zixhunywe kumthombo ofanayo wamanzi, imeko yokubuyela umva ingenzeka. Oku kwenzeka xa amanzi ebuyela umva ngenxa yokuhla ngokukhawuleza koxinzelelo, ukungcolisa umgca oyintloko kunye nokuwenza ungasetyenziselwa iinjongo zokucima umlilo.
Hlola iivalve ezifakwe kwiinkqubo zokukhusela umlilo zibonelela ngesisombululo esithembekileyo kule ngxaki. Iivalvu zokujonga zigcina ingqibelelo yonikezelo lwamanzi ngokuvumela amanzi ukuba ahambe ukusuka kumbhobho ukuya kwisixokelelwano sokucima umlilo kodwa ukuthintela amanzi ukuba abuyele umva. Oku kuqinisekisa ukuba abacimi-mlilo basoloko befikelela kumthombo wamanzi ococekileyo nothembekileyo, okubavumela ukuba balwe ngokufanelekileyo nemililo kwaye banciphise naziphi na iingozi ezinokubakho.
Ukongeza, iivalve zetshekhi zenzelwe ukusebenza ngokuzenzekelayo. Abafuni kungenelelo okanye ukubeka iliso komntu ukuze kusebenze ngokufanelekileyo. Olu phawu lubalulekile ngexesha likaxakeka xa abacimi-mlilo kufuneka bagxininise ekulawuleni umlilo kunokuba bakhathazeke ngokusebenza kakuhle kwezixhobo.
Ukushwankathela, ivalve yokukhangela sisixhobo esiyimfuneko ekukhuseleni umlilo. Badlala indima ebalulekileyo ekugcineni unikezelo lwamanzi ingqibelelo, ukuthintela ukungcoliseka kunye nokuqinisekisa ukuphendula ngokukhawuleza nangempumelelo kwiimeko ezingxamisekileyo zomlilo. Ngokuvumela ulwelo ukuba luhambe kwicala elinye kunye nokuthintela umva, ii-valve zokujonga zibonelela ngesisombululo esithembekileyo nesisebenzayo kwimingeni ejongene neshishini lokukhusela umlilo. Abacimi-mlilo banokuthembela kwezi zixhobo ukugcina izixhobo zamanzi zicocekile kwaye zifumaneka lula, zibavumela ukuba basebenze kakhulu ekusindiseni ubomi kunye nokukhusela impahla.
