ULondolozo lwaManzi olomeleziweyo ngeeValufa zePRV

Ukunciphisa ukumoshwa kwaManzi ekuvuzeni

Ukonakaliswa kwamanzi kubangela umngeni omkhulu kuthungelwano lwemibhobho yamanzi yasezidolophini. Ulawulo loxinzelelo ngokusebenzisa iValve yePRV idlala indima ebalulekileyo ekusombululeni lo mba. Ngokulawula uxinzelelo lwamanzi, ezi zivalo zinciphisa uxinzelelo kwimibhobho, zinciphisa amathuba okuvuza kunye nokugqabhuka. Amanqanaba asezantsi oxinzelelo nawo anciphisa isantya sokuhamba ngeentanda okanye imingxunya ekhoyo, ukuthintela ukulahleka kwamanzi.

• Ulawulo loxinzelelo luchaphazela ngqo amaxabiso olahleko lwamanzi. Uxinzelelo olongeziweyo luhlala lukhokelela kumazinga aphezulu okusilela kwemibhobho, okwenza mandundu ukonakala kwamanzi.
• Iindawo zoxinzelelo ezilungiselelwe ngokufanelekileyo zinciphisa ukuvuza, njengoko ukuvuza kuncipha ngokukhawuleza ngoxinzelelo oluphantsi. Le ndlela iphinda ibangele ukuqhawulwa kwemibhobho embalwa kunye neendleko eziphantsi zokumpompa.

NgokuphumezaIivalvu zePRV, oomasipala banokufikelela ekulondolozweni kwamanzi kakhulu. Ezi zivalo azithinteli kuphela ukulahleka kwamanzi ngokungeyomfuneko kodwa zikwaphucula ukusebenza kakuhle kweenkqubo zamanzi ezidolophini. Lo mlinganiselo uqinisekisa ukuba izibonelelo ezixabisekileyo zigcinelwe ukusetyenziswa kwixesha elizayo.

Ukukhuthaza uphuhliso lweDolophu oluZinzileyo

Uphuhliso lwedolophu oluzinzileyo luxhomekeke kulawulo olusebenzayo lwemithombo. Iivalvu zePRV zifaka isandla kule njongo ngokulungiselela ukusetyenziswa kwamanzi kuthungelwano lombhobho womlilo. Ukuthotywa kokuvuza kunye namanqanaba oxinzelelo alawulwayo aqinisekisa ukuba amanzi asetyenziswa ngokufanelekileyo, ukuxhasa uzinzo lwexesha elide lweendawo zasedolophini.

Ukongeza ekugcineni amanzi, iiValve zePRV zinciphisa ukusetyenziswa kwamandla. Amanqanaba oxinzelelo acuthiweyo anciphisa umthwalo wokusebenza kwiimpompo, okukhokelela kugcino olubalulekileyo lwamandla. Oku kuncitshiswa kokusetyenziswa kwamandla kuhambelana neenzame zehlabathi zokunciphisa iinyawo zekhabhoni kunye nokulwa nokutshintsha kwemozulu.

Oomasipala ababeka phambili imisebenzi ezinzileyo bayazuza ekudityanisweni kweeValve zePRV. Ezi zivalo aziphuculi kuphela ukuthembeka kweizixhobo zokucima umlilokodwa ikwakhuthaza ukulondolozwa kwendalo. Ngokutyala imali kwi-PRV Valves ephezulu, njengalezo ezinikezelwa yiYuyao World Fire Fighting Equipment Factory, izixeko zinokufikelela kwiinjongo zazo zokuzinza ngelixa ziqinisekisa ukhuseleko kunye nokusebenza kakuhle kweenkqubo zabo zamanzi.

Ukuziqhelanisa nokuKhula kweeDolophu eziXhaswa ngamaValufa ePRV

Ukuxhasa Ukwandiswa kweeNethiwekhi zeHydrant

Imimandla yasezidolophini ifumana ukukhula okuqhubekayo, kufuna uthungelwano lwezixhobo zokucima umlilo ukuze zande kwaye zilungele iimfuno ezintsha.Iivalvu zePRV zidlala indima ebalulekileyoekuxhaseni oku kwandiswa ngokuqinisekisa ulawulo loxinzelelo olungaguqukiyo kuthungelwano olukhulu. Njengoko izixeko zikhula, ukuntsonkotha kweenkqubo ze-hydrant kuyanda, nto leyo eyenza ukuba ukulawulwa koxinzelelo oluthembekileyo kubaluleke kakhulu ekugcineni ukusebenza kakuhle.

Uthungelwano lwasezidolophini lwale mihla luxhomekeke kwiisistim eziphambili ezifana ne-SCADA (ULawulo lokuLawula nokuFumana iDatha) ukubeka iliso nokulawula useto lwevalvu yePRV. Ezi nkqubo ziqokelela kwaye zisasaze idatha yexesha lokwenyani malunga nobume bevalvu kunye namanqanaba oxinzelelo, okwenza oomasipala bajongane nokuguquguquka kwangoko. Ukuqokelelwa kwedatha ngokuchanekileyo kuqinisekisa ukuba i-valve ye-PRV igcina uxinzelelo oluphezulu, ukukhusela umonakalo weziseko ezingundoqo kunye nokuqinisekisa ukuhanjiswa kwamanzi okuthembekileyo ngexesha likaxakeka. Izifundo zophando zigxininisa ukubaluleka kokuphonononga izicwangciso ze-PRV kunye nokuphanda imiba ye-SCADA ukuqinisekisa ukudityaniswa ngokungenamthungo kuthungelwano olwandisiweyo. Le ndlela isebenzayo ixhasa ukukhula kwedolophu ngelixa igcina imfezeko yeenkqubo zokucima umlilo.

Ukulawula iMfuno eyandisiweyo yaManzi

Ukukhula kwabemi kunye nophuhliso lwedolophu lukhokelela kwimfuno ephezulu yamanzi, ngakumbi kwiindawo ezinabantu abaninzi.Iivalvu zePRV zinceda ukulawulale mfuno yandayo ngokugcina uxinzelelo oluthe gqolo ezantsi komsinga, naxa iimeko zomntla ziguquguquka. Oku kuzinza kuqinisekisa ukuba izixhobo zokucima umlilo zihambisa amanzi ngokufanelekileyo, ukunciphisa umngcipheko wokunqongophala ngexesha likaxakeka.

Ulawulo loxinzelelo lukwanciphisa ukumoshwa kwamanzi, ukulondoloza imithombo kunye nokunciphisa iindleko zokusebenza. Amanqanaba oxinzelelo oluphantsi anciphisa amazinga okuvuza, anciphisa ilahleko yamanzi ngonyaka ukusuka kwi-189 yezigidi zeegaloni ukuya kwi-80 yezigidi zeegaloni. Oku kuncitshiswa akugcini nje ngokugcina amanzi kodwa kwandisa ixesha lokuphila lemibhobho kunye ne-hydrants ngokunciphisa uxinzelelo kwiziseko ezingundoqo. Iivalvu zePRV ziqhubela phambili ukwandisa ukusetyenziswa kwamanzi ngokwehlisa amazinga okuhamba, okucutha ukusetyenziswa kukonke kwaye kuxhase uphuhliso lwedolophu oluzinzileyo.

Oomasipala bayaxhamla kwindleko-zokusebenza kweevalvu ze-PRV, ngakumbi kwiindawo ezinemfuno ephezulu njengezithili eziphakamileyo ezidolophini. Ngexesha lokuhlawula emva kweminyaka emibini ukuya kwemine, ezi zivalo zibonelela ngesisombululo esisebenzayo sokulawula imfuno yamanzi ngelixa uqinisekisa iziseko ezithembekileyo zokucima umlilo.

Ukuthotyelwa kweMigangatho yoKhuseleko usebenzisa i-PRV Valves

IiMfuno zoLawulo lweNtlanganiso

Uthungelwano lwezixhobo zokucima umlilo ezidolophini kufunekathobela ukhuseleko olungqongqoimigangatho yokuqinisekisa ukusebenza okuthembekileyo ngexesha likaxakeka. Iivalvu zePRV zidlala indima ebalulekileyo ekuhlangabezaneni nezi mfuno zolawulo ngokugcina uxinzelelo lwamanzi olungaguqukiyo kunye nokukhusela iziseko zophuhliso. Ukuhlolwa rhoqo kunye neeprothokholi zokuvavanya ziqinisekisa ukuba ezi zivalo zisebenza njengoko kucetywayo, zinegalelo kukhuseleko olupheleleyo lweenkqubo zamanzi ezidolophini.

Imigangatho yoshishino icebisa ukuba kwenziwe uhlolo lwekota ukuqinisekisa ukuba uxinzelelo lokungena nokuphuma luhambelana neemfuno zokusebenza. Olu hlolo lukwaqinisekisa ukuba iivalvu zihlala kwindawo echanekileyo evulekileyo okanye evaliweyo, amavili ezandla aqinile, kwaye imisonto yombhobho ikwimeko entle. Uvavanyo lokuqukuqela kwenxalenye yonyaka luqinisekisa ukuba isitulo sevalvu sisuka kwindawo evaliweyo, ngelixa uvavanyo lokuqukuqela olupheleleyo rhoqo emva kweminyaka emihlanu luvavanya ukusebenza ngokupheleleyo kwevalve. Ezi zenzo zibonisa ukuthembeka kwee-valve ze-PRV ekubambeleleni kwimimiselo yokhuseleko kunye nokugcina ukunyaniseka kwenkqubo.

Ukuphucula intembeko yoluntu kwiziseko zophuhliso

Ukuthembela koluntu kwiziseko ezingundoqo zasezidolophini kuxhomekeke ekusebenzeni okungaguqukiyo kweenkqubo ezibalulekileyo ezifana nothungelwano lwemibhobho yamanzi.
