Kwihlabathi lokucima umlilo, ukubalwa kwesibini. Ukuba nezixhobo ezinokuthembekileyo kubalulekile ukuthintela ukulibaziseka kunye nokuqinisekisa ukhuseleko lwabacimi-mlilo kunye noluntu. Ivalve yokukhangela yelicebo elibalulekileyo lwezixhobo ezidlala indima ebalulekileyo kwiNkqubo yokuKhuthaza umlilo.
Ivalve yokukhangela sisixhobo somatshini ovumela amanzi ukuba ahambe kwicala elinye kuphela. Isetyenziswa ikakhulu kwiinkqubo zokukhuselwa komlilo ukuthintela i-backflow okanye ukubuyela umva. Ngesiciko sokucima umlilo, i-valves qinisekisa ukuba amanzi okanye i-fiffiriefinition foam ihamba ngendlela oyifunayo kwaye ayiphazamisi ukusebenza ngempumelelo kwenkqubo yokucima umlilo.
Ngexesha likaxakeka lomlilo, abacimi-mlilo baxhomekeke emanzini ukusuka kwii-hydrants kunye nemibhobho yokuphelisa amalangatye. Ngaphandle kwevalve yokujonga, ukubonelelwa kwamanzi kunokubanjiswa okanye ukonakala. Kwiimeko apho ii-hydrants zomzobo ezininzi ziqhagamshelwe kumthombo wamanzi ofanayo, imeko yokubetha inokwenzeka. Oku kwenzeka xa amanzi enyuka ngenxa yehla ngequbuliso kuxinzelelo, ukungcolisa umgca ophambili kwaye ukubonelela ngokungafanelekanga ngeenjongo zokucima umlilo.
Jonga iiValves ezifakwe kwiNkqubo yokuKhuselwa komlilo ibonelela ngesisombululo esinokuthenjwa kule ngxaki. Jonga i-valveves ukugcina ingqibelelo yobonelelo lwamanzi ngokuvumela amanzi ukuba ahambe kwi-hydrant kwinkqubo yokucinezelwa komlilo kodwa ukuthintela amanzi ukuba abuyele umva. Oku kuqinisekisa abacimi-mlilo bahlala befumana umthombo ococekileyo nothembekileyo wamanzi, obavumela ukuba balwe ngokufanelekileyo imililo kwaye unciphise nayiphi na imingcipheko enokubakho.
Ukongeza, jonga ii-valve zenzelwe ukusebenza ngokuzenzekelayo. Abafuni ungenelelo lomntu okanye iliso lokusebenza ukuze lisebenze ngokufanelekileyo. Eli nqaku libalulekile ngexesha likaxakeka xa abacimi-mlilo kufuneka bagxile ekulawuleni umlilo kunokuba sizixhalabise ngokusebenza ngokufanelekileyo kwezixhobo.
Ukuphamba, i-valve yokutshekisha sisixhobo esibalulekileyo kukhuseleko lomlilo. Badlala indima ebalulekileyo ekugcineni ingqibelelo yamanzi, ukuthintela ungcoliseko kunye nokuqinisekisa impendulo ekhawulezileyo nefanelekileyo kwimilo yemeko yonyango lomlilo. Ngokuvumela ulwelo ukuba ungene kwicala elinye kwaye uthintele umva, i-valves yokujonga ibonelela ngesisombululo esithembekileyo nefanelekileyo kwimizicelo ejongene nayo ngumzi mngeni wokukhusela umlilo. Abacimi-mlilo banokuxhomekeka kwezi zixhobo ukugcina izinto zezandla zicocekile kwaye zifumaneka ngokulula, zibavumela ukuba zisebenze kakhulu ekusindiseni ubomi kunye nokukhusela ipropathi.
