I-Pressure Reducing Valve E Type E idlala indima ebalulekile ekugcineni ukucindezela kwamanzi okungaguquki kumapayipi omlilo. Ivimbela ngokuphumelelayo ukulimala kwezinhlelo ze-hydrant ezibangelwa ukushintshashintsha kwengcindezi. Ngokusebenza okuthuthukisiwe, lokhuI-Valve Yokunciphisa Ingcindezi Yamanzikuthuthukisa kakhulu ukuphepha ngesikhathi sezimo eziphuthumayo zomlilo. Ngaphezu kwalokho, i-I-Valve Yokwehlisa IngcindezifuthiI-Valve Yokulawula Ukunciphisa Ingcindeziyizici ezibalulekile eziqinisekisa ukusebenza okuthembekile ezimweni ezibucayi.

Ukubaluleka Kwamavalvu Okunciphisa Ingcindezi

Iqhaza Ezinhlelweni Ze-Fire Hydrant

Ama-valve okwehlisa umfutho (ama-PRV) asebenza imisebenzi ebalulekile ezinhlelweni zamapayipi omlilo. Balawula umfutho wamanzi, baqinisekise ukuthi uhlala ngaphakathi kwemingcele ephephile. Lo mthethonqubo ubalulekile ekuvikeleni izicishamlilo kanye nempahla emonakalweni ongase udalwe amanzi anengcindezi ephezulu. Ithebula elilandelayo libonisa imisebenzi eyinhloko yama-valve okunciphisa ingcindezi ezinhlelweni zamapayipi omlilo:

Ngokugcina amazinga okucindezela azinzile, ama-PRV asiza ukunciphisa ingozi yokuvuza nokuqhuma kwamapayipi. Akhonjiswe ukuthi ehle amazinga okuvuza ngo-31.65%, anciphisa ukumoshwa kwamanzi. Ngaphezu kwalokho, ukusetshenziswa kwama-PRV kuholela ekwephukeni kwamapayipi okumbalwa, okwehlisa izindleko zokulungisa nokushintshwa. Lokhu kwethembeka kuqinisekisa ukuthi uhlelo lokuhlinzeka ngamanzi luhlala lungaphazamiseki ngesikhathi sezimo eziphuthumayo.

Umthelela Ekuhambisaneni Nokucindezela Kwamanzi

Ukungaguquguquki komfutho wamanzi kubalulekile ekusebenzeni kahle kwezinhlelo zamapayipi omlilo ngesikhathi sezimo eziphuthumayo.Umfutho wamanzi ophakeme ungalimaza izingxenye ezibalulekile, okuholela ekuhlulekeni kwemishini. Ingcindezi eguquguqukayo iphazamisa imisebenzi yokucisha umlilo, okwenza kube inselele kubacimi bomlilo ukugcina amanzi anganyakazi. Ingcindezi eyeqile ingaphinda iguqule amaphethini okufutha wezifafazi noma imibhobho, inciphise ukusebenza kwayo futhi ibambezele ukucisha umlilo.

Ububanzi obunconywayo bokucindezela kokusebenza kwe-fire hydrant, ngokusho kwezindinganiso zemboni, kugcizelela ukubaluleka kokugcina ingcindezi engaguquki. Isibonelo, i-NFPA 24 (2019) ikhombisa ukuthi amasistimu angenayo iphampu yomlilo ngokuvamile aweqi ku-150 PSI kumapayipi angaphansi komhlaba. Ukwengeza, i-NFPA 291 incoma ukugcinwa kwengcindezi eyinsalela engu-20 PSI ukuze kucishwe umlilo ngempumelelo.

Izici Zohlobo Lokunciphisa I-Valve E ye-Pressure E

Ukuklama nokusebenza

I-E Type Pressure Reducing Valve iziqhenya ngomklamo oqinile oklanyelwe ukusebenza kahle ezinhlelweni zamapayipi omlilo. Ukwakhiwa kwayo kusebenzisa ithusi elisezingeni eliphezulu, eliqinisekisa ukuqina nokumelana nokugqwala. I-valve ifaka i-inlet ene-flanged noma screwed, evumela izinketho zokufaka ezihlukahlukene.

Imininingwane yedizayini ebalulekile ihlanganisa:

I-valve yohlobo lwe-Eilawula umfutho wamanzingokulungisa ukugeleza okuvela emanzini amakhulu. Ivula ngokuzenzakalelayo noma ivale ngokuphendula izinguquko kwingcindezi yokungena ukuze kugcinwe ukucindezela kokuphuma okuzinzile. Lo mshini uqinisekisa umfudlana wamanzi othembekile kubacishi bomlilo, kungakhathaliseki ukushintshashintsha kwengcindezi yesistimu.

Ukuqina Nokwethenjelwa

Ukuqina kuwuphawu lwe-E Type Pressure Reducing Valve. Ngaphansi kwezimo ezijwayelekile zokusebenza, le valve inesilinganiso sokuphila cishe iminyaka eyisishiyagalombili. Kodwa-ke, le nkathi yokuphila ingahluka ngokuya ngezinqubo zokunakekela nezimo zokusebenza. Ukunakekelwa okuvamile, okufana nokulungiswa kabusha njalo eminyakeni emibili kuya kwemine, kunganweba kakhulu impilo yokusebenza kwevalvu.

Ukuthembeka kwe-valve yoHlobo luka-E kusuka enqubweni yayo yokuhlola eqinile. I-valve ngayinye ihlolwa umzimba kubha engu-30, okuqinisekisa ikhono layo lokumelana nezimo zengcindezi ephezulu. Leli zinga lokuhlola linikeza ukuthula kwengqondo kubasebenzisi, bazi ukuthi i-valve izokwenza ngokuphumelelayo phakathi nemisebenzi ebalulekile yokucisha umlilo.

Uma kuqhathaniswa nezinye izinhlobo zama-valve okunciphisa ingcindezi, Uhlobo lwe-E lunikeza umklamo olula onezingxenye ezimbalwa, okwenza kube ukukhetha ukonga. Kodwa-ke, kubalulekile ukuqaphela ukuthi ingaba nemikhawulo ekucindezelweni kokuvala kanye nesivinini se-actuator. Lezi zinto ziyenza ifaneleke kakhulu izinhlelo zokusebenza ezinoshintsho lokulayisha kancane.

Sekukonke, i-E Type Pressure Reducing Valve igqama ngenhlanganisela yayoumklamo ophumelelayo, ukusebenza okuthembekile, nokuqina, okuyenza ibe yingxenye ebalulekile ezinhlelweni zamapayipi omlilo.

Ukufakwa Nokugcinwa Kwevalve Yohlobo lwe-E

Imikhuba Engcono Kakhulu Yokufaka

Ukufakwa ngendlela efanele kweValve Yokunciphisa Ingcindezi Yohlobo E kubalulekile ekusebenzeni kahle. Ukulandela izinqubo ezihamba phambili kungavimbela amaphutha okufaka avamile. Nanka amaphuzu abalulekile okufanele uwacabangele:

• Ukufakwa Kume mpo: Njalo faka i-valve iqonde phezulu ukuze ugweme izinkinga zokusebenza futhi uqinisekise ukugeleza kwamanzi okufanele.
• Ukusekela Ukukhipha Ipayipi: Qinisekisa ukuthi amapayipi okukhiphayo asekela isisindo sawo. Lokhu kuvimbela ukucindezeleka ku-valve, okungathinta ukusebenza kwayo.
• Gcina Umehluko Wengcindezi: Gcina umehluko ofanele phakathi kokusebenza nokucindezela kokusetha. Lokhu kubalulekile ekusebenzeni kwe-valve.

Ukusebenzisa amathuluzi afanele nakho kuthuthukisa ukusebenza kahle kokufaka. Amathuluzi anconyiwe afaka:

• Isilinganiso somfutho
• Isikrini sepayipi
• I-Tubing cutter
• I-wrench evulekile
• Isikulufi

Amathiphu Okulungisa Okuvamile

Ukugcinwa kwesimiso kubalulekile ukuze kuphile isikhathi eside nokwethembeka kwe-valve Yohlobo lwe-E. Ukuhlola okuvamile kusiza ukuhlonza izinkinga ezingase zibe khona ngaphambi kokuba zande. Ithebula elilandelayo libonisa imisebenzi yokulungisa enconyiwe kanye nemvamisa yayo:

Izindlela zokulungisa ezisebenzayozihlanganisa:

• Ukuhlolwa okuvamile ukuze kuhlonzwe izinkinga ezingase zibe khona.
• Ukuhlanza nokugcoba izingxenye ezihambayo ukuvimbela ukuguga.
• Ukuqapha ukuvuza ukuze kuqinisekiswe ubuqotho besistimu.

Ngokunamathela kulokhuimihlahlandlela yokufaka nokugcinwa, abasebenzisi bangaqinisekisa ukuthi i-E Type Pressure Reducing Valve isebenza kahle, inikeza ukucindezela kwamanzi okuthembekile phakathi nemisebenzi ebalulekile yokucima umlilo.

I-E Type Pressure Reducing Valve ithuthukisa kakhulu ukusebenza nokuphepha kwe-fire hydrant. Ukuphathwa kwengcindezi engaguquki kuqinisekisa ukusabela okuphuthumayo okuthembekile. Ukutshala imali kumavalvu oHlobo luka-E kubonakala kunenzuzo, njengoba enciphisa ukuvuza nokuphuka kwamapayipi, okunciphisa ukuphazamiseka futhi avikele ingqalasizinda. Lokhu kutshalwa kwezimali kubalulekile ezinhlelweni ezisebenzayo zokuphepha emlilweni.
