Zeziphi iimfihlo ezingaziwayo kwintsebenzo yokutywina kweevali zokujonga? Kwinethiwekhi ye-Arterial "yoThutho lwemizi-mveliso, i-valves injenge-vabhu" abagcini-masango ", bavimba ngokuqinileyo i-medium efuna ukubaleka umva - kodwa ubusazi? Ukuzithemba kwayo okungagungqi akukaze kuphume umoya omncinci.

'NjengeGqibelelo' -omva "kwindlela yepayipi, jonga i-valves inomsebenzi ophambili wokunyanzela ukuhamba kwemidiya enye kunye nokuphelisa umngcipheko wokomsa. Esi sibonakaliso sivela kumdibaniso onzulu wokuyilwa kwendlela yayo yendlela kunye nemigaqo-nkqubo yoomatshini.

Uhlalutyo olupheleleyo lwamanyathelo okhuseleko lwe-Palve Palve I-visves yesango idlala indima ebalulekileyo ekulawuleni ukuhamba kwe-fluid kwiinkqubo zepayipi. Ufakelo olufanelekileyo lubalulekile ekusebenzeni kwabo kunye nokusebenza kwexesha elide.

Kwiinkqubo zemizi-mveliso yeplanga, i-vilves yesango zizinto eziphambili zokulawula ukuhamba kwamasango, phakathi kwendawo yokuphuma kwesango kunye neevalve ezifihliweyo ziqhelekileyo. Ke, zinyuka iivalves zesango elinyukayo zinokuthenjwa ngakumbi kune-valve efihlakeleyo?

Kutheni ukhetho lwe-Sango lwe-veli luhlala lunemigibe? Le migibe i-5 'engabonakaliyo' iphindwe kabini iindleko zobunjineli! Kwinkqubo yemisebenzi yemizi-mveliso, i-valves yesango zizixhobo ezibalulekileyo ze-cutoff.
