Kweli nqaku, siza kuhlola uphawu lwevalvu yokujonga, ukubaluleka kwayo, kunye neempawu ezahlukeneyo ezinxulumene neevalvu zokujonga, kuquka abavelisi, ababoneleli, amaxabiso, kunye neefektri, ingakumbi sigxile kumhlaba waseTshayina.
Yintoni iValve yokujonga
Ivalvu yokujonga, okwaziwa ngokuba yiivalvu engabuyisiyo, sisixhobo soomatshini esivumela ulwelo ukuba luhambe kwicala elinye ngelixa luthintela ukuba lungabuyeli umva. Oku kufezekiswa ngendlela elula edla ngokubandakanya idiski okanye ibhola ehamba ngaphakathi komzimba wevalvu. Xa ulwelo luhamba kwicala elicetywayo, idiski okanye ibhola iyatyhalwa ivuleke, ivumela indlela. Ukuba ukuhamba kuyajika, idiski okanye ibhola iyaphoqeleka ukuba ibuyele kwindawo evaliweyo, ivale ivalvu kwaye ithintele ukubuya kwamanzi.
Ukubaluleka kweeValvu zokujonga
Iivalvu zokujonga zibalulekile kwizicelo ezahlukeneyo, kuquka:
- Imibhobho: Ukuthintela ukubuya kwamanzi okunokonakalisa iimpompo nezinye izixhobo.
