Isimiso Sokusebenza Sokuvimbela Ukugeleza Kwe-Backflow
Isivimbeli sokugeleza emuva kwe-TWSiyithuluzi elenzelwe ukuvimbela ukugeleza kwamanzi angcolile noma ezinye izinto ezisetshenziswayo ohlelweni lokuphakelwa kwamanzi noma ohlelweni loketshezi oluhlanzekile, okuqinisekisa ukuphepha nobumsulwa bohlelo oluyinhloko. Isimiso salo sokusebenza sincike kakhulu ekuhlanganisweniama-valve okuhlola, izindlela zokwehluka kwengcindezi, kanye nama-valve okusiza ukudala "isithiyo" ekugelezeni emuva. Nansi incazelo eningiliziwe:
I-valve Yokuhlola EkabiliIndlela yokusebenza
Iningiizithiyo zokubuyela emuvafaka amavalvu amabili okuhlola asebenza ngokuzimela afakwe ochungechungeni. Ivalvu yokuqala yokuhlola (ukungenaivalvu yokuhlola) ivumela uketshezi ukuthi lugeleze luye phambili ohlelweni ngaphansi kwezimo ezijwayelekile kodwa luvala ngokuqinile uma kuvela ukucindezeleka emuva, okuvimbela ukugeleza okuphambene nohlangothi olungezansi. Okwesibiliivalvu yokuhlola(isitoloivalvu yokuhlola) isebenza njengesithiyo sesibili: uma okokuqalaivalvu yokuhlolauma yehluleka, eyesibili iyasebenza ukuvimba noma yikuphi ukugeleza okusele, okuhlinzeka ngesendlalelo sokuvikela esiphindaphindayo.
Ukuqapha Ukwehluka Kwengcindezi
Phakathi kwalaba ababiliama-valve okuhlola, kukhona igumbi lokuhlukanisa ingcindezi (noma indawo ephakathi). Ngaphansi kokusebenza okuvamile, ingcindezi ohlangothini lokungena (phezulu kwevalvu yokuhlola yokuqala) iphakeme kunengcindezi endaweni ephakathi, kanti ingcindezi endaweni ephakathi iphakeme kunecala lokukhipha (ezansi komfula wesibili).ivalvu yokuhlolaLokhu kuphakama kokucindezela kuqinisekisa ukuthi womabili ama-valve okuhlola ahlala evulekile, okuvumela ukugeleza phambili.
Uma ukugeleza komoya emuva kuseduze (isib., ngenxa yokwehla okungazelelwe komfutho ophezulu noma ukwanda komfutho ophansi), ibhalansi yomfutho iyaphazamiseka. Ivalvu yokuhlola yokuqala iyavalwa ukuze kuvinjelwe ukugeleza komoya emuva kusuka endaweni ephakathi kuya endaweni yokungena. Uma ivalvu yokuhlola yesibili ithola nomfutho obuyela emuva, iyavalwa ukuze ivimbele ukugeleza komoya emuva kusuka ohlangothini lokukhipha kuya endaweni ephakathi.
Ukusebenza kweValve Yokukhulula
Ama-relief blood amaningi afakwe i-relief valve exhunywe endaweni ephakathi. Uma womabili ama-check valve ehluleka noma uma ingcindezi endaweni ephakathi idlula ingcindezi yokungena (okubonisa ingozi engaba khona yokugeleza emuva), i-relief valve iyavuleka ukuze ikhiphe uketshezi olungcolile endaweni ephakathi iye emoyeni (noma ohlelweni lokukhipha amanzi). Lokhu kuvimbela uketshezi olungcolile ukuthi lubuyele emanzini ahlanzekile, kugcina ubuqotho bohlelo oluyinhloko.
Ukusebenza Okuzenzakalelayo
Yonke inqubo izenzekela, ayidingi ukungenelela ngesandla. Idivayisi isabela ngokuguquguqukayo ezinguqukweni zokucindezela koketshezi kanye nendlela yokugeleza, iqinisekisa ukuvikelwa okuqhubekayo ekubuyeni emuva ngaphansi kwezimo zokusebenza ezahlukahlukene.
Izinzuzo Zokuvimbela Ukugeleza Kwegazi
Izithiyo zokuvimbela ukugeleza emuvazidlala indima ebalulekile ekuvikeleni izinhlelo zamanzi, ikakhulukazi amanzi aphuzwayo, ngokuvimbela ukugeleza okuphambene kwezinto ezingcolile noma ezingafuneki. Izinzuzo zazo ezibalulekile zifaka:
1. **Ukuvikelwa Kwekhwalithi Yamanzi**
Inzuzo eyinhloko ukuvimbela ukungcoliswa okuxubile phakathi kwezinhlelo zamanzi ahlanzekile kanye nemithombo engeyona ehlanzekile (isb., amanzi angcolile ezimbonini, amanzi okunisela, noma indle). Lokhu kuqinisekisa ukuthi amanzi okuphuza noma uketshezi oluhlanzekile lwenqubo luhlala lungangcolisiwe, kunciphisa izingozi zempilo ezihlobene nokusetshenziswa kwamanzi angcolile.
2. **Ukuthobela Imithetho**
Ezifundeni eziningi, izinto zokuvimbela ukubuya kwamanzi ziyaphoqelelwa yimithetho yokufakwa kwamapayipi kanye nemithethonqubo yezempilo (njengaleyo ebekwe yizinhlangano ezifana ne-EPA noma iziphathimandla zamanzi zendawo). Ukuzifaka kusiza izikhungo nezinhlelo ukuhlangabezana nezidingo zomthetho, kugwenywe izinhlawulo noma ukuvalwa kokusebenza.
3. **Ukweqiwa kanye Nokuthembeka**
Iningiizithiyo zokubuyela emuvainezivilovu zokuhlola ezimbili kanye nezivilovu zokukhulula, okudala uhlelo lokuphepha olungasebenzi. Uma ingxenye eyodwa yehluleka, ezinye zisebenza njengezipele, zinciphisa ingozi yokugeleza emuva. Lo mklamo uqinisekisa ukusebenza okuqhubekayo ngisho nangaphansi kwezimo zokucindezela noma ukugeleza ezishintshashintshayo.
4. **Ukuguquguquka Kuzo Zonke Izinhlelo Zokusebenza**
Ziyakwazi ukuzivumelanisa nezimo ezahlukahlukene, okuhlanganisa nezinhlelo zokuhlala, zezentengiselwano, zezimboni, kanye nezomasipala. Kungakhathaliseki ukuthi zisetshenziswa kumanethiwekhi okufaka amapayipi, izinhlelo zokunisela, noma imigqa yenqubo yezimboni, izithiyo zokuvimbela ukugeleza kwamanzi emuva zivimbela ngempumelelo ukugeleza kwamanzi emuva kungakhathaliseki uhlobo loketshezi (amanzi, amakhemikhali, njll.) noma usayizi wesistimu.
5. **Ukunciphisa Umonakalo Wemishini**
Ngokumisa ukugeleza okuphambene, izithiyo zokuvimbela ukugeleza okungemuva zivikela amaphampu, ama-boiler, ama-water heater, nezinye izingxenye zesistimu emonakalweni obangelwa ukucindezeleka okungemuva noma isando samanzi (ukwanda kokucindezeleka okungazelelwe). Lokhu kwandisa isikhathi sokuphila kwemishini futhi kunciphisa izindleko zokulungisa.
6. **Ukusebenza Okuzenzakalelayo**
Izithiyo zokuvimbela ukugeleza emuvaisebenza ngaphandle kokungenelela ngesandla, isabela ngokushesha ezinguqukweni zokucindezela noma ekuguqulweni kokugeleza. Lokhu kuqinisekisa ukuvikelwa okuqhubekayo ngaphandle kokuthembela ekuqapheni komuntu, okwenza zifaneleke ezinhlelweni ezingenamuntu noma ezikude.
7. **Ukonga Izindleko**
Nakuba izindleko zokuqala zokufaka zikhona, ukonga kwesikhathi eside kukhulu. Kunciphisa izindleko ezihlobene nokuhlanza ukungcola kwamanzi, ukulungiswa kwemishini, izinhlawulo zomthetho, kanye necala elingaba khona ngenxa yezehlakalo zezempilo ezihlobene namanzi angcolile. Empeleni, izinto zokuvimbela ukubuya kwamanzi zibalulekile ekugcineni ubuqotho bohlelo, impilo yomphakathi, kanye nokusebenza kahle kuzo zonke izinhlelo zokusebenza ezisekelwe kuketshezi.
