Ngokuphucula ukusebenza, okuIvalvu Yokunciphisa Uxinzelelo Lwamanziiphucula kakhulu ukhuseleko ngexesha leengxamiseko zomlilo. Ukongeza,Ivalvu Yokunciphisa Uxinzelelo LokufikakwayeIvalvu yoLawulo lokunciphisa uxinzelelozizinto ezibalulekileyo eziqinisekisa ukusebenza okuthembekileyo kwiimeko ezinzima.
Ukubaluleka kweeValve zokunciphisa uxinzelelo
Indima kwiiNkqubo zoMbane
Iivalvu zokunciphisa uxinzelelo (ii-PRV) zisebenza imisebenzi ebalulekileyo kwiinkqubo ze-fire hydrant. Zilawula uxinzelelo lwamanzi, ziqinisekisa ukuba luhlala ngaphakathi kwemida ekhuselekileyo. Lo mgaqo ubalulekile ekukhuseleni abacimi-mlilo kunye nepropathi kumonakalo onokubakho obangelwa ngamanzi anoxinzelelo oluphezulu. Le theyibhile ilandelayo ichaza imisebenzi ephambili yeevalvu zokunciphisa uxinzelelo kwiinkqubo ze-fire hydrant:
| Inkcazo yomsebenzi |
|---|
| Ukunciphisa uxinzelelo lwenkqubo kunye nokunciphisa uxinzelelo lwayo. |
| Ukunciphisa amanqanaba oxinzelelo ukusuka kwisekethe ephambili ukuya kwisekethe encinci. |
| Ukulawula uxinzelelo lwenkqubo kwiindawo ezithile zesekethe. |
| Ukuthintela uxinzelelo oluphezulu lwenkqubo ukuba lungafikeleli kwinqanaba elingakhuselekanga. |
| Ukukhusela inkqubo kwiingcinezelo ezigqithisileyo zenkqubo. |
| Ukugcina uxinzelelo oluphezulu nokuba kukho uxinzelelo olutshintshatshintshayo. |
Ngokugcina amanqanaba oxinzelelo azinzileyo, ii-PRV zinceda ekunciphiseni umngcipheko wokuvuza kunye nokuqhuma kwemibhobho. Ziye zabonakala zinciphisa amazinga okuvuza ngama-31.65%, zinciphisa ukuchithwa kwamanzi. Ngaphezu koko, ukusetyenziswa kwee-PRV kukhokelela ekuqhekekeni kwemibhobho okuncinci, nto leyo enciphisa iindleko zokulungisa kunye nokutshintsha. Oku kuthembeka kuqinisekisa ukuba inkqubo yokubonelela ngamanzi ayiphazamiseki ngexesha leengxamiseko.
Impembelelo ekuNgaguquguquki koxinzelelo lwamanzi
Uxinzelelo lwamanzi lubalulekile ekusebenzeni kakuhle kweenkqubo zokucima umlilo ngexesha leengxamiseko.Uxinzelelo lwamanzi oluphezulu lungonakalisa izinto ezibalulekileyo, nto leyo ekhokelela ekungasebenzi kakuhle kwezixhobo. Uxinzelelo olutshintshatshintshayo luphazamisa imisebenzi yokulwa nomlilo, nto leyo eyenza kube nzima kubacimi-mlilo ukugcina umjelo wamanzi uzinzile. Uxinzelelo olugqithisileyo lunokutshintsha iipatheni zokutshiza zee-sprinkler okanye ii-nozzles, ukunciphisa ukusebenza kwazo kunye nokulibazisa ukucima umlilo.
Uluhlu loxinzelelo olucetyiswayo lokusebenza kwe-fire hydrant, ngokwemigangatho yeshishini, lugxininisa ukubaluleka kokugcina uxinzelelo oluqhubekayo. Umzekelo, i-NFPA 24 (2019) ibonisa ukuba iinkqubo ezingenayo ipompo yomlilo azidluli kwi-150 PSI kwimibhobho engaphantsi komhlaba. Ukongeza, i-NFPA 291 icebisa ukugcina uxinzelelo oluseleyo lwe-20 PSI ukuze kuliwe umlilo ngempumelelo.
Iimpawu zohlobo lwe-E yeValve yokunciphisa uxinzelelo
