Ukhuseleko lomlilo lubaluleke kakhulu kwizakhiwo, kwizakhiwo zoshishino nakwimisebenzi yaselwandle. Phakathi kwezinto ezahlukeneyo zeenkqubo zokukhusela umlilo,iivalvu zokukhusela umlilozidlala indima ebalulekileyo ekuqinisekiseni ukuthembeka, ukulawula ukuhamba kwamanzi, nokukhusela ubomi kunye neempahla. Ukuqonda imisebenzi kunye neenzuzo zazo kunokunceda abaphathi beziko kunye neenjineli baphucule amanyathelo okhuseleko lomlilo.
Ukuqinisekisa Ukuhamba Kwamanzi Okukhawulezayo Ngexesha LeeNgxakeko
Iivalvu zokukhusela umlilo, ezifana neevalvu zesango, iivalvu zebhabhathane, kunye neevalvu zokujonga, zenzelwe ukulawula nokuhamba kwamanzi okanye izinto zokucima umlilo. Xa i-alamu yomlilo ivuliwe, ezi valve ziqinisekisa ukuba amanzi aziswa ngoko nangoko kwaye ngoxinzelelo oluchanekileyo kwiinkqubo zokutshiza, ii-hydrants, okanye iipayipi. Olu kusabela ngokukhawuleza lubalulekile ekucinezeleni imililo ngaphambi kokuba isasazeke, ukunciphisa umonakalo wepropathi kunye nokusindisa ubomi.
Ukuthintela ukubuya kwe-Backflow kunye nongcoliseko
Iinkqubo ezininzi zokukhusela umlilo ziqhagamshelwe kwimithombo yamanzi kamasipala. Ukubuyela umva kwamanzi kunokubangela ungcoliseko lwamanzi acocekileyo, okubeka ukhuseleko esichengeni. Jonga iivalvu okanye iivalvu ezingabuyiyo kwiinkqubo zokukhusela umlilo zithintela ukuhamba okungasemva, ukuqinisekisa ukuba amanzi aya kuphela kwindawo yomlilo kwaye akhusele imithombo yamanzi okusela.
Ukugcina uBulungisa beNkqubo
Iivalvu zokukhusela umlilo zakhiwe ukuze zimelane noxinzelelo oluphezulu, amaqondo obushushu aphezulu, kunye neemeko zokubola. Izinto ezihlala ixesha elide ezifana nebronze, intsimbi engatyiwayo, okanye intsimbi ephosweyo ziqinisekisa ukusebenza ixesha elide ngaphandle kokuvuza okanye ukusilela. Ukuhlolwa rhoqo kunye nokugcinwa kwezi valve kunceda ukugcina ukuthembeka kwenkqubo, ukuqinisekisa ukuba inkqubo isebenza ngokuthembekileyo xa ifuneka kakhulu.
Ukwahlula iiCandelo ukuze kulungiswe okanye kulawulwe umonakalo
Iivalvu ezifana neevalvu zokuvala okanye iivalvu zokwahlukanisa zivumela iindawo ezithile zenkqubo yokukhusela umlilo ukuba zilungiswe ngaphandle kokuvala inethiwekhi yonke. Oku kubaluleke kakhulu kwizakhiwo ezinkulu, iinqanawa, okanye izityalo zoshishino apho ixesha lokungasebenzi ngokupheleleyo kwenkqubo linokuba yingozi. Ukuzahlula iindawo kukwavumela impendulo ekhawulezileyo kwimeko yomonakalo ngengozi kwiindawo ezithile zemibhobho.
Ukuthobela iMigangatho yoKhuseleko loMlilo
Iivalvu zokukhusela umlilo kufuneka zihambelane nemigangatho yamazwe ngamazwe neyengingqi, efana ne-NFPA (National Fire Protection Association), i-UL (Underwriters Laboratories), kunye nemigangatho ye-ISO. Ukuthobela imithetho kuqinisekisa ukuba iivalvu ziyahlangabezana neemfuno zomgangatho, ukusebenza, kunye nokhuseleko oluqinileyo. Ukusebenzisa iivalvu eziqinisekisiweyo kunciphisa uxanduva, kuphucula ukhuseleko, kwaye kuqinisekisa abalawuli ukuba iinkqubo zithembekile kwaye ziyasebenza.
Ukuxhasa iiNkqubo zoKhuseleko loMlilo oluQhelekileyo
Iinkqubo zokukhusela umlilo zanamhlanje ziya kudibanisa ngakumbi ubuchwepheshe obukrelekrele, obufana nezinzwa zoxinzelelo kunye nokubeka esweni ngokuzenzekelayo. Iivalvu zokukhusela umlilo zisebenza kakuhle nezi nkqubo, zivumela ulawulo lwexesha langempela kunye nokusebenza kude. Izilumkiso ezizenzekelayo zinokubonisa ukusilela kwevalvu okanye uxinzelelo oluphantsi, okuvumela isenzo sokulungisa ngokukhawuleza ngaphambi kokuba umlilo unyuke.
