Isithinteli seMini Backflow esikumgangatho ophezulu esivela kwi-TWS
Inkcazo:
Uninzi lwabemi alufaki isixhobo sokuthintela ukugeleza kwamanzi emva kombhobho wabo wamanzi. Bambalwa abantu abasebenzisa ivalvu yokujonga eqhelekileyo ukuthintela ukugeleza kwamanzi emva kombhobho. Ngoko ke iya kuba ne-ptall enkulu enokubakho. Kwaye uhlobo oludala lwesixhobo sokuthintela ukugeleza kwamanzi emva kombhobho lubiza kakhulu kwaye alulula ukulukhupha. Ngoko ke kwakunzima kakhulu ukusetyenziswa kakhulu kwixesha elidlulileyo. Kodwa ngoku, siphuhlisa uhlobo olutsha ukuze sisombulule yonke into. Isixhobo sethu sokuthintela ukugeleza kwamanzi emva kombhobho siza kusetyenziswa kakhulu kumsebenzisi oqhelekileyo. Esi sisixhobo sokudibanisa amandla ombane ngokulawula uxinzelelo kumbhobho ukuze kuzaliseke ukuhamba kwamanzi ngendlela enye. Siya kuthintela ukugeleza kwamanzi emva kombhobho, siphephe imitha yamanzi eguqulweyo kunye ne-anti drip. Siya kuqinisekisa amanzi okusela akhuselekileyo kwaye sithintele ungcoliseko.
Iimpawu:
1. Uyilo oluqinileyo oluthambileyo, ukumelana nokugeleza kwamanzi okuphantsi kunye nengxolo ephantsi.
2. Ulwakhiwo oluncinci, ubungakanani obufutshane, kulula ukuyifaka, yonga indawo yokufaka.
3. Ukuthintela ukuguquka kwemitha yamanzi kunye nemisebenzi ephezulu yokulwa nokurhoxa kwamanzi,
Ukuthontsiza amanzi kunceda kakhulu ekulawuleni amanzi.
4. Izinto ezikhethiweyo zinobomi obude benkonzo.
Umgaqo Wokusebenza:
Yenziwe ngeevalvu ezimbini zokujonga ezisebenzisa intambo
uqhagamshelo.
Esi sisixhobo sokudibanisa amandla ombane ngokusebenzisa ulawulo loxinzelelo olukwipayipi ukuze kuzaliseke ukuhamba kwamanzi ngendlela enye. Xa amanzi efika, iidiski ezimbini ziya kuvulwa. Xa ema, uya kuvalwa yintwasahlobo yawo. Iya kuthintela ukuhamba kwamanzi umva kwaye iphephe imitha yamanzi ejikayo. Le valve inenye inzuzo: Iqinisekisa ukulingana phakathi komsebenzisi kunye ne-Water Supply Corporation. Xa ukuhamba kuncinci kakhulu ukuba kungatshajwa (okufana: ≤0.3Lh), le valve iya kuyisombulula le meko. Ngokwenguquko yoxinzelelo lwamanzi, imitha yamanzi iyajika.
Ufakelo:
1. Coca umbhobho ngaphambi kokuba uwufake kwi-insalting.
2. Le valve ingafakwa ngokuthe tye nangokuthe nkqo.
3. Qinisekisa ukuba ulwalathiso oluphakathi kunye nolwalathiso lotolo olukwindawo efanayo xa ulufaka.
