A Ivalvu Yokucisha Umliloisebenza njengengxenye ebalulekile ezinhlelweni zokuphepha emlilweni. Ilawula ukugeleza kwamanzi kusuka ku-hydrant kuya epayipini lomlilo ngesikhathi sezimo eziphuthumayo. Ukuqonda izici zayo kusiza ukuqinisekisa impendulo esheshayo kanye nokusebenza okuthembekile.

Ulwazi olufanele ngama-valve okushisa umlilo lungenza umehluko ezimweni eziphuthumayo.

Izinto Ezibalulekile Okufanele Uzicabangele

• Amavalvu okususa umlilolawula ukugeleza kwamanzi kanye nengcindezi, ukusiza abacishi bomlilo ukuletha amanzi ngendlela ephumelelayo nephephile ngesikhathi sezimo eziphuthumayo.
• Izinhlobo ezahlukene zama-valve, njenge-globe, isango, i-angle, kanye ne-dry barrel, kunikeza izinzuzo ezithile njengokulawula ukugeleza okunembile, ukukhishwa kwamanzi okusheshayo, ukwakheka okonga isikhala, kanye nokuvikelwa kokuqandisa.
• Ukulandela izindinganiso zokuphepha kanye nokugcinwa njalo kuqinisekisa ukuthi ama-valve asebenza ngokwethembeka, kuvikela izimpilo, impahla, kanye nemithombo yamanzi yomphakathi.

Imisebenzi Eyinhloko kanye nezici Eziyinhloko ze-Fire Hydrant Valve

Ukulawula Ukugeleza

Ivalvu Yokucisha Umlilo ivumela abacishi bomlilo ukuphatha ukugeleza kwamanzi ngesikhathi sezimo eziphuthumayo. Bangavula noma bavale ivalvu ukuze baqale noma bamise ukuhamba kwamanzi. Lokhu kulawula kusiza ukuqondisa amanzi lapho edingeka khona. Abacishi bomlilo bathembele kulesi sici ukuze bacime umlilo ngokushesha.

Icebiso: Ukulawula ukugeleza okufanele kungenza ukulwa nomlilo kube ngcono futhi kunciphise imfucuza yamanzi.

Ukulawulwa Kwengcindezi

Ukulawulwa kwengcindeziimelela njengesici esibalulekile sawo wonke ama-Fire Hydrant Valve. Lawa ma-valve asiza ukugcina umfutho wamanzi uzinzile epayipini. Uma umfutho uphezulu kakhulu, amapayipi noma imishini ingaphuka. Uma umfutho wehla kakhulu, amanzi angase angafiki emlilweni. I-valve iqinisekisa ibhalansi efanele yokulwa nomlilo okuphephile nokuphumelelayo.

Ukugeleza Okuzinzile	Iqinisekisa ukuthi amanzi afinyelela emlilweni

Ukulondolozwa Kwamanzi

Amavalvu Okushisa Umlilo asiza ukonga amanzi ngesikhathi sezimo eziphuthumayo zomlilo. Ngokulawula inani lamanzi akhishwayo, avimbela imfucuza engadingekile. Abacishi bomlilo bangasebenzisa amanzi abawadingayo kuphela. Lesi sici sivikela imithombo yamanzi yendawo futhi sisekela ukuphepha kwemvelo.

• Kunciphisa ukulahleka kwamanzi
• Isekela ukulwa ngomlilo okusimeme
• Ivikela izinsiza zomphakathi

Ukuqina Nokunakekelwa

Abakhiqizi baklama ama-Fire Hydrant Valve ukuze ahlale isikhathi eside ezimweni ezinzima. Basebenzisa izinto eziqinile njengethusi noma insimbi engagqwali. Lawa ma-valve amelana nokugqwala kanye nomonakalo ovela esimweni sezulu.Ukunakekelwa okuvamileZigcina zisebenza kahle. Ukuhlola okulula nokuhlanza kusiza ukuvimbela izinkinga ngesikhathi sezimo eziphuthumayo.

Qaphela: Ukuhlolwa okuvamile kuqinisekisa ukuthi i-Fire Hydrant Valve ihlala ithembekile futhi ilungele ukusetshenziswa.

Izinhlobo ze-Fire Hydrant Valve

Amavalvu Embulunga

Amavalvu e-globe asebenzisa isimo somzimba esiyindilinga. Alawula ukugeleza kwamanzi ngokuhambisa idiski phezulu naphansi ngaphakathi kwevalvu. Lo mklamo uvumela ukulungiswa okunembile kokugeleza kwamanzi. Abacishi bomlilo bavame ukukhetha amavalvu e-globe lapho bedinga ukulungisa ukulethwa kwamanzi. Lawa mavalvu asebenza kahle ezimweni ezidinga ukucindezela kwamanzi okuzinzile nokulawulwayo.

Qaphela: Ama-valve e-Globe angaphatha izinhlelo zokucindezela okuphezulu futhi anikeze amakhono okuvala athembekile.

Amavalvu Esango

Amavalvu esango asebenzisa isango eliyisicaba noma elinomumo ofana ne-wedge ukuvimba noma ukuvumela ukugeleza kwamanzi. Lapho isango liphakama, amanzi ahamba ngokukhululeka ngevalvu. Lapho isango lehla, limisa ukugeleza ngokuphelele. Amavalvu esango anikeza ukumelana okuncane uma evuliwe ngokuphelele. Izinhlelo zokuphepha emlilweni zivame ukusebenzisa la mavalvu ngoba avumela ukukhishwa kwamanzi okusheshayo nokugcwele.

• Ukusebenza okulula
• Ukwehla kwengcindezi okuphansi
• Ifanelekela amanzi amaningi

Amavalvu e-engela

Ama-valve e-engela ashintsha indlela yokugeleza kwamanzi ngama-degree angu-90. Lo mklamo usiza ukulinganaIvalvu Yokucisha Umliloezindaweni eziqinile. Ama-valve e-engela enza kube lula ukuxhuma amapayipi ngezindlela ezahlukene. Izinhlelo eziningi zokufaka amanzi omlilo zisebenzisa ama-valve e-engela ukuze zivumelane nezimo zazo kanye nezinzuzo zokonga isikhala.

Ushintsho Lokugeleza Okungu-90°	Ifanelana ezindaweni ezincane
Ukuxhumanisa Amapayipi Okulula	Ukufakwa okuguquguqukayo

Amavalvu Omgqomo Owomile

Amavalvu ebhareli elomile avikela ekuqandeni ezindaweni ezibandayo. Indlela eyinhloko yamavalvu ihlala ngaphezu komhlaba, kuyilapho amanzi ehlala ngaphansi komgqa weqhwa. Lapho abacishi bomlilo bevula ivalvu, amanzi akhuphukela epayipini lokuhambisa amanzi. Lo mklamo uvimbela amanzi ukuthi ahlale ebharelini futhi aqande. Amavalvu ebhareli elomile agcina ama-fire hydrant elungele ukusetshenziswa, ngisho nasebusika.

Icebiso: Amavalvu ebhareli elomile abalulekile ezindaweni ezinobusika obunzima.

Izindinganiso Zokuthobela Nokuphepha Zevalvu Yokucisha Umlilo

Amakhodi Nemithethonqubo Efanele

Amazwe amaningi abeka imithetho eqinile yemishini yokuphepha emlilweni. Le mithetho isiza ukugcina abantu nempahla bephephile. Amavalvu okufaka amanzi omlilo kumele ahlanganeamazingakusuka emaqenjini afana neNational Fire Protection Association (NFPA) kanye ne-American Water Works Association (AWWA). Ohulumeni basekhaya nabo bangase babe namakhodi abo. Lawa makhodi atshela abakhi nonjiniyela ukuthi bangafaka futhi basebenzise kanjani amavalvu okushisa umlilo.

Ukulandela le mithetho kusiza ukuvimbela izingozi futhi kuqinisekise ukuthi uhlelo lusebenza ngesikhathi sezimo eziphuthumayo.

Ukubaluleka Kwesitifiketi

Isitifiketikufakazela ukuthi ivalvu yokucima umlilo ihlangabezana nezindinganiso zokuphepha nekhwalithi. Amalabhorethri okuhlola, njenge-Underwriters Laboratories (UL) noma i-FM Approvals, ahlola ivalvu ngayinye. Afuna ukuvuza, amandla, kanye nokusebenza okufanele. Amavalvu aqinisekisiwe kuphela angasetshenziswa ezinhlelweni eziningi zokuvikela umlilo.

• Ama-valve aqinisekisiwe anikeza ukuthula kwengqondo.
• Zibonisa ukuthi umkhiqizo uphumelele izivivinyo ezinzima.
• Izinkampani eziningi zomshuwalense zidinga imishini eqinisekisiwe.

Umthelela Ekuphepheni Nasekusebenzeni

Ukuthobela imithetho efanele kanye nesitifiketi kuthuthukisa ukuphepha. Baqinisekisa ukuthi ivalvu yokucima umlilo iyasebenza uma kudingeka. Ivalvu eqinisekisiwe izovuleka futhi ivalwe ngaphandle kwezinkinga. Ngeke ivuze noma iphuke ngaphansi kwengcindezi.

Ivalvu Yokucisha Umlilo inikeza ukulawula ukugeleza okubalulekile kanye nokuqina kwezinhlelo zokuvikela umlilo. Ukukhetha okufanele kanye nokuhambisana nezindinganiso zokuphepha kuqinisekisa ukusebenza okuthembekile. Abacishi bomlilo bathembele kula mavalvu ukuze banikeze amanzi ngokushesha. Indima yabo ekuphepheni komlilo kanye nokuthembeka kohlelo isabalulekile kuyo yonke imiphakathi.

Icebiso: Ukuhlolwa njalo kusiza ukugcina ukusebenza okuphezulu.

Imibuzo Evame Ukubuzwa

Yiziphi izinto ezisetshenziswa abakhiqizi kuma-valve okufaka amanzi omlilo?

Abakhiqizi bavame ukusebenzisa ithusi, insimbi engagqwali, noma insimbi ethambile. Lezi zinto ziyamelana nokugqwala kanye nomonakalo, okuqinisekisa ukusebenza okuhlala isikhathi eside ezindaweni ezinzima.

Amavalvu omshini wokushisa umlilo kufanele anakekelwe kangaki?

Ochwepheshe batusa ukuhlola nokulungisa ama-valve okushisa umlilo okungenani kanye ngonyaka. Ukuhlolwa okuvamile kusiza ekuvimbeleni ukungasebenzi kahle futhi kuqinisekise ukusebenza okuthembekile ngesikhathi sezimo eziphuthumayo.

Ingabe ama-valve okushisa umlilo angasetshenziswa emazingeni okushisa abandayo?

Yebo. Amavalvu ebhareli omile avikela ekuqandeni. Agcina amanzi ngaphansi komhlaba kuze kube yilapho esetshenziswa, okwenza afaneleke ezimweni ezibandayo nasezimweni zasebusika.
