Uma kuziwa ezinhlelweni zokuvikela umlilo, ingxenye ngayinye idlala indima ebalulekile ekuqinisekiseni ukuphepha kwesakhiwo kanye nabahlali baso.I-valve yokuhlola iyingxenye ebalulekile enjalo.I-valve yokuhlola iyithuluzi elibalulekile ohlelweni lokuvikela umlilo.Isetshenziselwa ukuvimbela amanzi noma olunye uketshezi ukuthi lungabuyeli emuva nokuqinisekisa ukugeleza kwamanzi okungaphazamiseki ezimeni eziphuthumayo.Kulesi sihloko, sizoxoxa ngokuthi kungani kubalulekile ukusebenzisa ama-valve okuhlola ezinhlelweni zokuvikela umlilo.
Okokuqala, ama-valve okuhlola adlala indima ebalulekile ekugcineni ubuqotho bamanzi akho.Ezinhlelweni zokuvikela umlilo, ama-valve okuhlola aqinisekisa ukuthi amanzi ageleza ohlangothini olulodwa kuphela, ngokuvamile esuka endaweni eyinhloko yokuhambisa amanzi kuya ezintweni zokuvikela umlilo.Lokhu kugeleza kwendlela eyodwa kubalulekile ukuze kuqinisekiswe ukuthi amanzi afinyelela lapho aya khona ngokushesha ngesikhathi sesigameko somlilo.Ngaphandle kwe-valve yokuhlola, amanzi angakwazi ukusekela, okubangela ukulahlekelwa umfutho wamanzi futhi ngokunokwenzeka kubangele uhlelo lokuvikela umlilo lwehluleke.
Esinye isizathu sokusebenzisa ama-valve okuhlola ekucimeni umlilo ukuvimbela ukungcola.Lawa ma-valve asiza ukugcina ukuhlanzeka kwamanzi akho ngokuvimbela noma yikuphi ukubuya okubuyayo okungangenisa izinto zangaphandle noma ukungcola ohlelweni.Ukungcoliswa kwamanzi kungaphazamisa kakhulu ukusebenza kwezifafazi zomlilo, izicisha-mlilo nezinye izinto zokucisha umlilo.Ngokusebenzisa ama-valve okuhlola, singaqinisekisa ukuthi amanzi ahlala ehlanzekile futhi engenakho ukungcola.
Ngaphezu kwalokho, ama-valve okuhlola akhulisa ukuthembeka okuphelele nokusebenza kahle kwesistimu yokuvikela umlilo.Basiza ukunciphisa ubungozi bokulimala kwepompo nokugcina ukucindezela kwamanzi njalo ngokuvimbela amanzi ukuthi asekele.Ngokugcina ukugeleza kwamanzi okungaguquki, ama-valve okuhlola asekela ukusebenza kahle kwezinhlelo zokufafaza umlilo, ama-hose reels, ama-hydrants nezinye izinto zokuvikela umlilo.Lokhu kuqinisekisa ukuthi lezi zingxenye zihlale zikulungele ukuthatha isinyathelo ngokushesha uma kwenzeka umlilo, ukuvimbela izingozi ezingase zibe khona kanye nokulimala kwempahla.
Kafushane, ukusetshenziswa kwama-valve okuhlola ezinhlelweni zokuvikela umlilo kubalulekile ngenxa yezizathu ezihlukahlukene.Bagcina ubuqotho bokunikezwa kwamanzi, bavimbele ukungcoliswa, futhi bakhulise ukwethembeka okuphelele nokusebenza kahle kohlelo.Ngaphandle kwevalvu yokuhlola, ukugeleza kwamanzi kungahlehla, kubangele ukulahlekelwa umfutho wamanzi kanye nokwehluleka okungenzeka kwalo lonke uhlelo lokuvikela umlilo.Ngakho-ke, kuyadingeka ukutshala ama-valve okuhlola izinga eliphezulu ahlangabezana nezindinganiso ezidingekayo futhi uwagcine njalo ukuze aqinisekise ukusebenza kwawo okufanele.Ngokwenza lokhu, sifaka isandla ekuvikelekeni nasekuphumeleleni kwezinhlelo zokuvikela umlilo, ukuvikela impilo kanye nempahla uma kwenzeka umlilo.
