ISISHWANKATHELO : Ivalve yokujonga irabha, ekwaziwa ngokuba yivalve yedada, ivelufa engabuyiyo kunye nevalve yendlela enye, ngesiqhelo ivumela ulwelo ukuba ludlule kuyo kwicala elinye kuphela.UHenan Lanphan uhlalutye uncedo lwevalve ye-duckbill esetyenziswa kwiprojekthi yokuhambisa amanzi olwandle.
Ivalve yokujonga irabha, ekwaziwa ngokuba yivalve yedada, ivelufa engabuyiyo kunye nevalve yendlela enye, idla ngokuvumela ulwelo ukuba luhambe kuyo kwicala elinye kuphela.Ivalve yokukhangela irabha isetyenziswa ngokubanzi kwiprojekthi yokuhambisa amanzi kunye nesikhululo sokumpompa, uHenan Lanphan uhlalutye uncedo lwevalve ye-duckbill esetyenziswa kwiprojekthi yokuhambisa amanzi olwandle.
I-Rubber Check Valve
Ivalve yokukhangela irabha esetyenziswa kwiprojekthi yokuhambisa amanzi olwandle ukugcina isantya esiphezulu sejethi.Kwiprojekthi yesiqhelo yokukhupha amanzi olwandle, incam yejethi isidayamitha esisigxina, ngoko ke isantya sokuhamba kwejethi siyenyuka kunye nokonyuka kokuhamba, kunye nevalve yokukhupha ephantsi ihambelana nesantya esisezantsi sokuqukuqela kwejethi.Nangona kunjalo, indawo yokuphuma yevalve yokukhangela irabha iya kunyuka kunye nokunyuka kwevalve yokukhupha.
Ivalve ye-Duckbill esetyenziswa kwiprojekthi yokukhupha amanzi olwandle ukuthintela ukungena kwamanzi olwandle kunye nentlenga.Ubuninzi bamanzi olwandle kunye namanzi amdaka ahlukile, i-duckbill yevalve yokukhangela irabha iyatshintshwa ngokuhamba, xa ivalve yokukhupha amanzi amdaka inguziro, ivalve yedada ikwimeko ekufutshane.Kwakhona ivelufa yedada isenayo isantya esiphezulu sejethi kwivalve yokukhuphela esezantsi, inqanda ngokufanelekileyo ungenelelo lwamanzi olwandle kunye namanzi amdaka.
Ivalve ye-Duckbill esetyenziswa kwiprojekthi yokukhupha amanzi olwandle ukuze kuxhamle umbhobho okhuphayo wokuvasa.Ukuba ivelufa yedada efakwe kumbhobho wokukhupha, amanzi amdaka angaphuma kuyo yonke imibhobho yokunyuka kwimeko yevalve yokukhuphela ephantsi, ngokunyuka kwevalve yokukhupha, amanzi olwandle asezantsi kombhobho aya kutsalwa ngaphandle.
Ivalve ye-Duckbill ifakwe kwiprojekthi yokuhambisa amanzi olwandle ukufumana ukunyuswa okuphezulu.Iziphumo zovavanyo lwemodeli zibonisa ukuba ivalve yokujonga irabha inokufumana ukunyuswa kwamanzi amdaka aphezulu kunencam yejethi esisigxina.
Ivalve yokukhangela irabha esetyenziswa kwimijelo yamanzi olwandle ukunqanda umhlwa.Amalungu esinyithi afakwe emanzini olwandle ixesha elide, kulula ukugqwala kunye nokugqwala, ngelixa i-valve yokukhangela irabha yenziwe ngezinto zerabha, irabha inomsebenzi obalaseleyo wokuchasana nomhlwa.
