I-TWS Backflow Preventer

Isimiso Esisebenzayo Se-Backflow Preventer

I-TWS backflow preventeriwumshini oklanyelwe ukuvimbela ukugeleza okubuyela emuva kwamanzi angcolile noma enye imidiya ohlelweni lokuphakela amanzi aphuzekayo noma isistimu yoketshezi oluhlanzekile, eqinisekisa ukuphepha nokuhlanzeka kwesistimu eyinhloko. Umgomo wayo wokusebenza uncike ngokuyinhloko ekuhlanganisweni kwehlola ama-valve, izindlela zokuhlukanisa ingcindezi, futhi ngezinye izikhathi ama-valve okusiza ukudala "umgoqo" ngokumelene nokubuyela emuva. Nansi incazelo enemininingwane:

I-Dual Check ValveIndlela
Iningibackflow preventershlanganisa ama-valve okuhlola amabili azimele afakwe ochungechungeni. I-valve yokuqala yokuhlola (i-inlethlola i-valve) ivumela uketshezi ukuthi lugeleze luye phambili ohlelweni ngaphansi kwezimo ezijwayelekile kodwa luvale ngokuqinile uma kwenzeka ukucindezela okungemuva, kuvimbele ukugeleza okubuyela emuva ukusuka ohlangothini olungezansi lomfula. Owesibilihlola i-valve(outlethlola i-valve) isebenza njengesithiyo sesibili: uma esokuqalahlola i-valveyehluleka, eyesibili iyasebenza ukuze ivimbe noma yikuphi ukugeleza okusele okusele, inikeze ungqimba olungadingekile lokuvikela.

Ukuqapha Okuhlukile Kokucindezela
Phakathi kokubilihlola ama-valve, kunegumbi lokuhlukanisa ingcindezi (noma indawo emaphakathi). Ngaphansi kokusebenza okuvamile, ingcindezi ohlangothini lokungena (enhla komfula we-valve yokuqala yokuhlola) iphakeme kunokucindezela endaweni ephakathi nendawo, futhi ingcindezi endaweni ephakathi iphakeme kunohlangothi lokuphuma (ezansi komfula wesibili).hlola i-valve). Le gradient yokucindezela iqinisekisa ukuthi womabili ama-valve okuhlola ahlala evulekile, okuvumela ukugeleza phambili.

Uma ukugeleza okubuyela emuva kuseduze (isb, ngenxa yokwehla kungazelelwe kwengcindezi ekhuphuka nomfula noma ukuphakama komfutho ophansi komfula), ibhalansi yengcindezi iyaphazamiseka. I-valve yokuhlola yokuqala iyavalwa ukuze kuvinjelwe ukugeleza emuva ukusuka endaweni emaphakathi kuya endaweni yokungena. Uma i-valve yokuhlola yesibili iphinda ithole ingcindezi ehlehlayo, ivala ukuvimba ukugeleza emuva ukusuka ohlangothini lokuphuma kuya endaweni emaphakathi.

I-Relief Valve Activation
Abavimbeli abaningi bokubuyela emuva bafakwe i-valve yokusiza exhunywe endaweni ephakathi. Uma womabili ama-valve okuhlola ehluleka noma uma ingcindezi endaweni emaphakathi idlula ingcindezi yokungena (okubonisa ingozi engase ibe khona yokubuyela emuva), ivalvu yokukhulula iyavuleka ukuze ikhiphe uketshezi olungcolile endaweni emaphakathi ukuya emkhathini (noma isistimu yokudonsa amanzi). Lokhu kuvimbela uketshezi olungcolile ukuthi lungaphindi lubuyele emanzini ahlanzekile, lugcine ubuqotho besistimu eyinhloko.

Ukusebenza okuzenzakalelayo
Lonke lolu hlelo luyazenzakalela, aludingi ukungenelela okwenziwa ngesandla. Idivayisi isabela ngokuguquguqukayo ezinguqukweni zengcindezi yoketshezi kanye nesiqondiso sokugeleza, iqinisekisa ukuvikeleka okuqhubekayo ekugelezeni emuva ngaphansi kwezimo zokusebenza ezihlukene.

Izinzuzo ze-Backflow Preventers

Izivimbeli zokugeleza kwe-backflowidlala indima ebalulekile ekuvikeleni amasistimu oketshezi, ikakhulukazi amanzi aphuzwayo, ngokuvimbela ukugeleza okubuyela emuva kwemidiya engcolile noma engathandeki. Izinzuzo zabo ezibalulekile zihlanganisa:

1. **Ukuvikelwa Kwekhwalithi Yamanzi**

Inzuzo eyinhloko ukuvimbela ukungcoliswa phakathi kwezinhlelo zamanzi aphuzwayo kanye nemithombo engaphuzwayo (isb., amanzi angcolile ezimbonini, amanzi okunisela, noma indle). Lokhu kuqinisekisa ukuthi amanzi okuphuza noma uketshezi lwezinqubo ezihlanzekile kuhlala kungangcolisiwe, kunciphisa izingozi zezempilo ezihlobene nokusetshenziswa kwamanzi angcolile.

2. **Ukuthobela Umthetho**

Ezifundeni eziningi, abavimbeli bokubuyela emuva bagunyazwe amakhodi okufaka amapayipi nemithetho yezempilo (njengaleyo ebekwe izinhlangano ezifana ne-EPA noma iziphathimandla zamanzi zendawo). Ukuzifaka kusiza izikhungo namasistimu ukuhlangabezana nezidingo zomthetho, ukugwema izinhlawulo noma ukuvalwa kokusebenza.

3. **Ukungadingeki kanye Nokwethenjwa**

Iningibackflow preventersifaka ama-valve okuhlola amabili kanye ne-valve yokukhulula, okwenza uhlelo lokuphepha olungadingekile. Uma ingxenye eyodwa ihluleka, ezinye zisebenza njengezipele, zinciphisa ubungozi bokubuyela emuva. Lo mklamo uqinisekisa ukusebenza okungaguquki ngisho nangaphansi kwengcindezi eguquguqukayo noma izimo zokugeleza.

4. **Ukuhlukahluka Kuzo Zonke Izicelo**

Ziyakwazi ukuzivumelanisa nezimo ezihlukahlukene, okuhlanganisa izindawo zokuhlala, ezohwebo, izimboni, kanye nezinhlelo zikamasipala. Kungakhathaliseki ukuthi isetshenziselwa amanethiwekhi amapayipi, amasistimu okunisela, noma imigqa yezinqubo zezimboni, abavimbeli bokubuyela emuva bavimbela ngokuphumelelayo ukugeleza emuva kungakhathaliseki uhlobo lwamanzi (amanzi, amakhemikhali, njll.) noma usayizi wesistimu.

5. **Ukunciphisa Ukulimala Kwezisetshenziswa**

Ngokumisa ukugeleza okubuyela emuva, abavimbeli be-backflow bavikela amaphampu, ama-boilers, izifudumezi zamanzi, nezinye izakhi zesistimu emonakalweni obangelwa ukucindezela okungemuva noma isando samanzi (ukuphakama komfutho okungazelelwe). Lokhu kwandisa isikhathi sokuphila kwemishini futhi kunciphisa izindleko zokunakekela.

6. **Ukusebenza Okuzenzakalelayo**

Izivimbeli zokugeleza kwe-backflowukusebenza ngaphandle kokungenelela okwenziwa ngesandla, ukuphendula ngokushesha ezinguqukweni zengcindezi noma ukuguqulwa kokugeleza. Lokhu kuqinisekisa ukuvikeleka okuqhubekayo ngaphandle kokuncika ekuqapheni abantu, okubenza bafanelekele amasistimu angenamuntu noma akude.

7. **Ukusebenza Kwezindleko**

Nakuba izindleko zokufaka zokuqala zikhona, ukonga kwesikhathi eside kubalulekile. Banciphisa izindleko ezihlobene nokuhlanza ukungcoliswa kwamanzi, ukulungiswa kwemishini, izinhlawulo ezingokomthetho, kanye nesibopho sezomthetho esingaba khona sezehlakalo zezempilo ezihlobene namanzi angcolile. Empeleni, abavimbeli be-backflow babalulekile ekugcineni ubuqotho besistimu, impilo yomphakathi, nokusebenza kahle kuzo zonke izinhlelo zokusebenza ezisekelwe kuketshezi.
