I-Mini Backflow Preventor
Ihlathululo:
Inengi labahlali alifaki isivimbeli sokugeleza kwamanzi emuva epayipini lazo. Bambalwa abantu abasebenzisa i-valve yokuhlola ejayelekileko ukukhandela ukubuyela emuva. Njeke kuzokuba ne-ptall ekulu. Begodu umhlobo omdala wesivimbeli sokugeleza emuva uyabiza begodu akulula ukuwukhipha. Ngalokho bekubudisi khulu ukusetjenziswa khulu esikhathini esidlulileko. Kodwana nje, sithuthukisa umhlobo omutjha ukurarulula koke. Isivikeli sethu esincani sokuvimbela ukuthoba sizokusetjenziswa khulu kumsebenzisi ovamileko. Lokhu kusisetjenziswa sokulawula amandla wamanzi ngokusebenzisa ukulawula umfutho ngaphakathi kwepayipi ukufezekisa ukugeleza kwendlela eyodwa. Kuzokuvimbela ukugeleza emuva, kugweme imitha yamanzi ephendukileko begodu ivikele ukuthosa. Kuzokuqinisekisa amanzi wokusela aphephileko begodu kuvimbele ukusilaphazeka.
Amatshwayo:
1. Idizayini yokuminyana okuqondileko, ukujamelana nokugeleza okuphasi kanye nomsindo omncani.
2. Isakhiwo esincani, ubukhulu obufitjhani, ukufaka lula, ukonga isikhala sokufaka.
3. Vimbela ukuphenduka kwemitha yamanzi kanye nemisebenzi ephezulu yokulwisana nokungasebenzi,
ukuthosa ngokuqinileko kuyasiza ekuphathweni kwamanzi.
4. Iinsetjenziswa ezikhethiweko zinesikhathi eside sokuphila.
Umthethomgomo wokusebenza:
Yakhiwe ngamavalvu amabili wokuhlola nge-threaded
ukuxhumana.
Lokhu kusisetjenziswa sokulawula amandla wamanzi ngokusebenzisa ukulawula umfutho ngaphakathi kwepayipi ukwenzela bona kufezeke ukugeleza kwendlela eyodwa. Lokha nakufika amanzi, amadiski amabili azokuvuleka. Lokha nayijamako, izokuvalwa mthombo wayo. Kuzokuvimbela ukugeleza emuva begodu kugweme imitha yamanzi ephendukileko. Ivalvu le inenye inzuzo: Iqinisekisa ukulunga hlangana nomsebenzisi neNkampani yokuPhakelwa kwaManzi. Lokha ukugeleza kuncani khulu ukukutjhaja (njengokuthi: ≤0.3Lh), ivalvu le izokurarulula ubujamo lobu. Ngokuya ngokutjhuguluka kwengcindezi yamanzi, imitha yamanzi iyajika.
Ukufakwa:
1. Hlanza ipayipi ngaphambi kokufakwa.
2. Ivalvu le ingafakwa ngendlela evundlileko nejameleko.
3. Qinisekisa bona indlela yokugeleza ephakathi kanye nendlela yomcibisholo kuyafana lokha nawufakwako.
