Iziphumo zokufakelwa ngokungachanekanga kweevalves zebhola zinexabiso kwaye akufuneki zijongelwe phantsi Ukuba kukho impazamo ekufakweni kweeValves zeBhola, iya kubangela uthotho lweziphumo ezibi, echaphazela ukusebenza kwale nkqubo.

Esona sixhobo sihlala sihlala ngakumbi kwiivali zebhola Phakathi kweentlobo ngeentlobo zeevalve, iivila zeBhola zisetyenziswa ngokubanzi kwimimandla eyahlukeneyo ngenxa yobume babo obulula, ukuvulwa ngokukhawuleza, ukuvalwa ngokukhawuleza, kunye nokuvalwa kwendlela yokutywina. Ukuqina kweevalves zebhola kunxulumene ngokusondeleyo nokukhethwa kwempahla, kwaye i-valve yebhola eyenziwe ngezinto ezahlukeneyo zilungele iimeko ezahlukeneyo zomsebenzi.

Ungayisombulula njani ingxaki yokutywina kakubi kweevalves zebhola? I-valves ivalve isetyenziswa ngokubanzi kwimveliso yemizi-mveliso kunye nokusetyenziswa kwemihla ngemihla ngenxa yezibonelelo zazo zokuvula ngokukhawuleza nokuvalwa, njl.

Jonga iValves, ekwabizwa ngokuba zii-valves enye, zisetyenziselwa ukuthintela ukubuyela umva kwe-hid kunye neenkqubo ezininzi zemizi-mveliso kunye nezomsebenzi, ngeentlobo ezahlukeneyo.

Ngaba uhlala unexhala ngamanzi angena kwimibhobho xa ubuyela emanzini emva kokuba amanzi anqunyulwe ekhaya?

Umzi-mveliso wenkqubo owomileyo ubekhona phantse iminyaka engama-20, kwaye abantu bahlala bebuza ngeevavu zetsheki, "ingaba le nto ingamelana nale nto?" Kuya kufuneka uyazi ukuba i-valve yetsheki, 'njengabagcini-phepha---indlela yendlela, "ayifuni nje ukuthintela i-backflow
