Ivalve yokukhangela ibhabhathaneibhekisa kwivalve ezivula ngokuzenzekelayo kwaye ivale i-flap yevalve ngokuxhomekeke ekuhambeni kwendawo ephakathi ngokwayo kwaye isetyenziselwa ukuthintela okuphakathi ukuba kungabuyeli ngasemva.Ikwabizwa ngokuba yivalve engabuyiyo, ivalve yendlela enye, ivalve yokubuyela umva, kunye nevalve yoxinzelelo yangasemva.
 
Uphawu loyilo
 
Iivalvu zokujonga ibhabhathanezibandakanya iivalvu zokujonga ujingi kunye neevalvu zokukhangela zokuphakamisa.Iivalvu zokujonga i-swing zinehinge mechanism kunye ne-valve flap efana nocango oluhlala ngokukhululekileyo kwindawo yesitulo sevalve.Ukuqinisekisa ukuba ivalve clack inokufikelela kwindawo eyiyo yomphezulu wesitulo sevalve ngalo lonke ixesha, isivalo sevalve siyilwe kwindlela yehenjisi ukuze intonga ibenendawo yokujinga eyaneleyo kunye noqhagamshelwano nesitulo sevalvu ngokubanzi.I-valve clack inokwenziwa ngesinyithi ngokupheleleyo, okanye isinyithi efakwe ngesikhumba, irabha, okanye isigqubuthelo sokwenziwa, kuxhomekeke kwiimfuno zokusebenza.Ngaphandle koko, xa ivalve yokujonga ujingi ivulwe ngokupheleleyo, uxinzelelo lolwelo luphantse lungathintelwa.Ngoko ke, ukuhla koxinzelelo ngevalve kuncinci.
 
I-disc yevalve yokukhangela i-lift ibekwe kwindawo yokutywina yesihlalo sevalve.Ngaphandle kokuba idiski yevalve inokunyuka kwaye iwe ngokukhululekileyo, yonke ivalve ifana nevalve yeglowubhu.Uxinzelelo lolwelo lunyanzela idiski yevalve ukuba iphakanyiswe ukusuka kwindawo yokutywina yesihlalo sevalve, kwaye umva ophakathi ubangela ukuba idiski yevalve iwele umva kwisitulo sevalve kwaye inqumle ukuhamba.Ngokwesiseko semiqathango yokusetyenziswa, i-valve clack ingaba yinto yonke-intsimbi okanye inokufakwa kunye nesakhiwo se-rubber pads okanye i-rubber rings kwisakhelo sayo.Njengeevalvu zokumisa, indlela yolwelo kwivalve yokujonga ilimxinwa.Ngaloo ndlela, ukuhla koxinzelelo ngevalve yokukhangela i-lift likhulu kunelo levalve yokujonga i-swing, kwaye isantya sokuhamba kwevalve yokukhangela i-swing ayifane iphele.Iivalvu zolu hlobo ziya kufakwa ngokuthe tye kwimibhobho.
