Emhlabeni wokucisha umlilo, umzuzwana ngamunye ubalulekile.Ukuba nemishini ethembekile kubalulekile ekuvimbeleni ukubambezeleka kanye nokuqinisekisa ukuphepha kwabacimi bomlilo kanye nomphakathi.I-valve yokuhlola iyisisetshenziswa esibalulekile esidlala indima ebalulekile ohlelweni lokuvikela umlilo.
I-valve yokuhlola iyithuluzi lomshini elivumela uketshezi ukuthi lugeleze luye ohlangothini olulodwa kuphela.Isetshenziswa kakhulu ezinhlelweni zokuvikela umlilo ukuvimbela ukugeleza emuva noma ukuhlehla.Ekucimeni umlilo, hlola ama-valve aqinisekisa ukuthi amanzi noma i-foam yokucima umlilo igeleza ngendlela oyifunayo futhi ayiphazamisi ukusebenza kahle kwenqubo yokucima umlilo.
Ngesikhathi sezimo eziphuthumayo zomlilo, izicishamlilo zithembele emanzini aphuma ku-hydrant namapayipi ukuze bacime ngokushesha amalangabi.Ngaphandle kwe-valve yokuhlola, amanzi angangcoliswa noma alimale.Ezimweni lapho amapayipi omlilo amaningi exhunywe emthonjeni ofanayo wamanzi, kungase kwenzeke isimo sokubuyela emuva.Lokhu kwenzeka lapho amanzi ehlehla ngenxa yokwehla kwengcindezi kungazelelwe, angcolise ulayini oyinhloko futhi awenze ungasebenziseki ngezinjongo zokucisha umlilo.
Ama-valve okuhlola afakwe ezinhlelweni zokuvikela umlilo ahlinzeka ngesixazululo esinokwethenjelwa kule nkinga.Ama-valve okuhlola agcina ubuqotho bokunikezwa kwamanzi ngokuvumela amanzi ukuba ageleze esuka ku-hydrant eya ohlelweni lokucindezela umlilo kodwa avimbele amanzi ukuthi abuyele emuva.Lokhu kuqinisekisa ukuthi izicishamlilo zihlala zifinyelela emthonjeni wamanzi ohlanzekile nothembekile, okubavumela ukuthi balwe ngokuphumelelayo nemililo futhi banciphise noma yiziphi izingozi ezingaba khona.
Ukwengeza, ama-valve okuhlola enzelwe ukusebenza ngokuzenzakalelayo.Azidingi ukungenelela komuntu noma ukugadwa ukuze zisebenze kahle.Lesi sici sibalulekile ngesikhathi sezimo eziphuthumayo lapho izicishamlilo zidinga ukugxila ekulawuleni umlilo kunokuba zikhathazeke ngokusebenza okufanele kwemishini.
Ukufingqa, i-valve yokuhlola iyithuluzi elibalulekile ekuvikelweni komlilo.Badlala indima ebalulekile ekugcineni ubuqotho bokunikezwa kwamanzi, ukuvimbela ukungcoliswa kanye nokuqinisekisa ukusabela okusheshayo nangempumelelo ezimweni eziphuthumayo zomlilo.Ngokuvumela uketshezi ukuba lugeleze ohlangothini olulodwa futhi luvimbele ukubuyela emuva, ama-valve okuhlola ahlinzeka ngesixazululo esinokwethenjelwa nesisebenzayo ezinseleleni ezibhekene nemboni yokuvikela umlilo.Izicishamlilo zingathembela kulawa madivaysi ukuze agcine amanzi ahlanzekile futhi etholakala kalula, okuwavumela ukuba aphumelele kakhulu ekusindiseni ukuphila nasekuvikeleni impahla.
