Izici Zomkhiqizo:
1. Uhlobo olujwayelekile lungafakwa ngokuqondile nangokuvundlile.
2. Ukufakwa kwezinga lokuphepha, indawo yesizinda kufanele ihlanzeke, kube nendawo yokulungisa eyanele, idrayini yokuphepha noma (i-air blocker) ingaphezu kuka-300M M ngaphezu komhlaba, futhi ayicwiliswa ngamanzi noma imfucumfucu.
3. Izinsiza zokudonsa amanzi kufanele zifakwe endaweni yokufaka.
4. I-valve yesango (i-valve uvemvane) kanye ne-rubber soft joint (noma i-expander) kufanele kufakwe ngaphambi kwe-valve, futhi i-valve yesango (i-valve uvemvane) kufanele ifakwe ngemva kwe-valve.Uma izinga lamanzi liphansi, uhlelo lokuhlola kufanele lufakwe ngaphambi kwe-valve.
Incazelo enemininingwane:
I-valve yokuhlukanisa i-anti-fouling ene-filter yakhiwe ama-valve okuhlola amabili ahlukene kanye nokudluliselwa kwe-hydraulic ku-valve yokudonsa.Umzimba wokuqala we-valve wokuhlola ufakwe isikrini sokuhlunga.Ngenxa yokulahlekelwa kwekhanda lendawo ye-valve yokuhlola, ukucindezela emgodini ophakathi kuhlale kuphansi kunokucindezela endaweni yokungena kwamanzi.Lo mehluko wengcindezi ushayela i-valve yokudonsa esimweni esivaliwe, futhi ipayipi ngokuvamile linikeza amanzi.Uma ingcindezi ingavamile, (okungukuthi, ingcindezi ekugcineni iphezulu kune-core cavity), ngisho noma ama-valve okuhlola amabili engakwazi ukuvaleka ngokuphambene, i-valve yokukhipha ukuphepha ingavuleka ngokuzenzakalelayo ukuze ikhiphe amanzi abuyele emuva futhi yakhe ukuhlukaniswa komoya ukuqinisekisa ukuthi ukhuphuka nomfula Ukuhlinzekwa kwamanzi kuhlanzekile futhi kuphephile.
ipharamitha yezobuchwepheshe:
Ukucindezela okulinganiselwe: 1. 0~2.5m Pa
Ubukhulu obujwayelekile: 50-60m m
Indawo esebenzayo: amanzi
Izinga lokushisa elisebenzayo: 0~80℃
Sebenzisa isikhathi:
Ama-backflow preventers ngokuvamile asetshenziswa ezimweni ezilandelayo:
1. Ukuphambana kwepayipi lamanzi okuphuza kanye namapayipi amanzi okuphuza axhunyiwe angewona awekhaya (ukucisha umlilo, ukukhiqiza, ukuchelela, ukuvikelwa kwemvelo, ukufafaza, njll.) amapayipi.
2. Amanzi ompompi kamasipala axhunywe endaweni yokukhipha amanzi yomsebenzisi eduze kwemitha yamanzi oyisebenzisayo.
3. Amanzi akhukhula ipayipi lapho kuphuma khona ipayipi elihambisa amanzi.
4. Epayipini lokumunca lepayipi lamanzi okuphuza elixhunywe ochungechungeni ngepompo ye-booster noma izinhlobo eziningi zemishini ye-booster.
5. Inethiwekhi yamapayipi amanzi okuphuza ezakhiwo ezihlukahlukene kanye namapayipi angavumeli ukuthi okuphakathi kugeleze emuva ekukhiqizeni.
