Ngokusebenza okuphuculweyo, okuIValve yokunciphisa uxinzelelo lwamanziiphucula kakhulu ukhuseleko ngexesha likaxakeka lomlilo. Ukongeza, iUxinzelelo lokuNcitshiswa kweValve yokuHlalisakwayeIValve yoLawulo lokuNcitshiswa koxinzelelozizinto ezibalulekileyo eziqinisekisa ngakumbi ukusebenza okuthembekileyo kwiimeko ezinzima.

Ukubaluleka kweeValufa zokuNciphisa uxinzelelo

Indima kwiiNkqubo zeHydrant yoMlilo

Iivalvu zokunciphisa uxinzelelo (i-PRVs) zisebenza imisebenzi ebalulekileyo kwiinkqubo zokucima umlilo. Balawula uxinzelelo lwamanzi, beqinisekisa ukuba luhlala luphakathi kwemida ekhuselekileyo. Lo mmiselo ubalulekile ekukhuseleni abacimi-mlilo kunye nepropathi kumonakalo onokuthi ubangelwe ngamanzi anoxinzelelo oluphezulu. Le theyibhile ilandelayo ichaza imisebenzi ephambili yokunciphisa uxinzelelo kwiinkqubo zombhobho womlilo:

Ngokugcina amanqanaba oxinzelelo oluzinzileyo, ii-PRVs zinceda ukunciphisa umngcipheko wokuvuza kunye nokuqhuma kwemibhobho. Zibonakaliswe ukuba zehlise izinga lokuvuza nge-31.65%, ukunciphisa ukumoshwa kwamanzi. Ngaphezu koko, ukuphunyezwa kwee-PRV kukhokelela ekuqhekekeni kwemibhobho embalwa, ethoba iindleko zokulungisa kunye nokutshintshwa. Oku kuthembeka kuqinisekisa ukuba inkqubo yokubonelela ngamanzi ihlala ingaphazamiseki ngexesha likaxakeka.

Ukuchaphazeleka koxinzelelo lwamanzi ukungaguquguquki

Ukungaguquguquki koxinzelelo lwamanzi kubalulekile ekusebenzeni kweenkqubo zombhobho womlilo ngexesha likaxakeka.Uxinzelelo lwamanzi oluphezulu lungonakalisa amacandelo abalulekileyo, ekhokelela ekungasebenzi kakuhle kwezixhobo. Uxinzelelo oluguquguqukayo luphazamisa imisebenzi yokucima umlilo, okwenza kube nzima kubacimi-mlilo ukugcina umsinga wamanzi ozinzileyo. Uxinzelelo olugqithisileyo lunokuguqula iipateni zokutshiza zezitshizi okanye imilomo, ukunciphisa ukusebenza kwazo kunye nokulibazisa ukucima umlilo.

Uluhlu olucetyiswayo loxinzelelo lomsebenzi womlilo womlilo, ngokwemigangatho yoshishino, lugxininisa ukubaluleka kokugcina uxinzelelo oluqhubekayo. Ngokomzekelo, i-NFPA 24 (2019) ibonisa ukuba iinkqubo ezingenampompo yomlilo azidli ngaphezu kwe-150 PSI kwimibhobho engaphantsi komhlaba. Ukongeza, i-NFPA 291 incoma ukugcina uxinzelelo olushiyekileyo lwe-20 PSI ukwenzela ukulwa nomlilo okusebenzayo.

Iimpawu zoHlobo lokuNcitshiswa kweValve E

Uyilo kunye nokusebenza
