Iindaba zeShishini

Kwiinkqubo ezahlukeneyo zezamashishini, iivawuts zizinto eziphambili ukuthintela ukubuyela umva kwemidiya kwaye isetyenziswe ngokubanzi ekunikezelweni kwamanzi kunye nokuntywila, i-Ploinage, amandla ombane, amanye amashishini.

Kwiinkqubo zemizi-mveliso zeplanga, i-valves yesango luhlobo lwe-valve esetyenziswa rhoqo, ikakhulu isetyenziselwa ukufezekisa ulawulo olupheleleyo oluvulekileyo okanye olupheleleyo lwendawo ephakathi kumbhobho.

Jonga ivalve yivalve ethintela ukubuyela umva kwemidiya. Inoluhlu olubanzi lwezicelo kwimimandla eyahlukeneyo. Oku kulandelayo zeziganeko zeseti ze-valves yokujonga:

I-valve yesango luhlobo oluqhelekileyo lwevalve ngezi zinto zilandelayo: Isakhono esihle sokusika
