Emhlabeni wokucima umlilo, wonke amacala wesibili. Ukuba nemishini ethembekile kubalulekile ekuvikeleni ukubambezeleka nokuqinisekisa ukuphepha kwabacishamlilo kanye nomphakathi. I-valve yesheke iyisiqeshana esibalulekile semishini edlala indima ebalulekile ohlelweni lokuvikela umlilo.
I-valve yesheke iyithuluzi elilungisiwe elivumela uketshezi ukuthi lugeleze endaweni eyodwa kuphela. Isetshenziswa ikakhulukazi ezinhlelweni zokuvikela umlilo ukuvikela ukugeleza emuva noma ukubuyela emuva. Ngokucisha umlilo, bheka ama-valves aqinisekisa ukuthi i-foam yamanzi noma yokucisha izicishamlilo igeleza endaweni oyifunayo futhi ingaphazamisi ukusebenza kahle kwenqubo yokucisha umlilo.
Ngesikhathi sezimo eziphuthumayo zomlilo, abacimi bomlilo bathembela emanzini kusuka kuma-hydrants namapayipi ukucisha amalangabi. Ngaphandle kwe-valve yokuhlola, ukuhanjiswa kwamanzi kungangcoliswa noma kulinyazwe. Ezimweni lapho ama-hydrant omlilo amaningi exhunywe emthonjeni wamanzi ofanayo, kungavela isimo esingemuva. Lokhu kwenzeka lapho amanzi ebuyela emuva ngenxa yehla ngokungazelelwe ekucindezelweni, engcolisa umugqa oyinhloko futhi uyisebenzise ngokungasebenziseki ngezinhloso zokucima umlilo.
Bheka ama-valves afakwe ezinhlelweni zokuvikela umlilo anikeza isixazululo esithembekile kule nkinga. Bheka ama-valves agcina ubuqotho bokuhlinzekwa kwamanzi ngokuvumela amanzi ukuthi ageleze kusuka ku-hydrant kuya kuhlelo lokucindezela umlilo kodwa ukuvimbela amanzi ekugelezeni emuva. Lokhu kuqinisekisa ukuthi abacishimlilo bahlala benokufinyelela emthonjeni wamanzi ohlanzekile nothembekile, okubavumela ukuba balwe ngempumelelo imililo futhi banciphise noma yiziphi izingozi ezingaba khona.
Ngokwengeziwe, ama-valves okuhlola aklanyelwe ukusebenza ngokuzenzakalelayo. Azidingi ukungenelela komuntu noma ukuphathwa umsebenzi ukuze kusebenze kahle. Lesi sici sibaluleke kakhulu ngesikhathi sezimo eziphuthumayo lapho abacimi bomlilo kudingeka bagxile ekulawuleni umlilo kunokuba bakhathazeke ngokusebenza okufanele kwemishini.
Ukufingqa, i-valve yesheke iyithuluzi elisemqoka ekuvikelweni komlilo. Badlala indima ebalulekile ekugcineni ubuqotho bamanzi, ukuvimbela ukungcoliswa nokuqinisekisa ukuphendula okusheshayo nokusebenzayo kwezimo eziphuthumayo. Ngokuvumela uketshezi ukuthi lugeleze endaweni eyodwa futhi luvimbele emuva, bheka ama-valves ahlinzeka ngesisombululo esithembekile nesisebenza kahle ezinseleleni ezibhekene nomkhakha wokuvikela umlilo. Izicishamlilo zingathembela kulezi zinto ukuthi zigcine izinsiza zamanzi zihlanzekile futhi zitholakala kalula, zibavumela ukuba ziphumelele kakhulu ekusindiseni izimpilo nokuvikela impahla.
