Isebenza njani ivalve?

Khangela iivalvuisenokusetyenziswa kwimigca ebonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokwenyuka ngaphezu koxinzelelo lwenkqubo.Iivalvu zokujonga zinokwahlulwa ikakhulu zibe ziivalve zokujonga ujingi (ezijikelezayo ngokweziko lomxhuzulane) kunye neevalvu zokukhangela (zihamba nge-axis).
Injongo yolu hlobo lwesivalo kukuvumela ukuba i-medium ihambe kwicala elinye kuphela kwaye ithintele ukuhamba kwelinye icala.Ngokuqhelekileyo olu hlobo lwesivalo lusebenza ngokuzenzekelayo.Ngaphantsi kwesenzo soxinzelelo lwe-fluid ehamba kwicala elinye, i-valve flap ivula;xa ulwelo luqukuqela kwelinye icala, uxinzelelo lolwelo kunye ne-self-coincident i-valve flap ye-valve flap isebenza kwisitulo sevalve, ngaloo ndlela inqumle ukuhamba.
Phakathi kwabo, i-valve yokukhangela yolu hlobo lwevalve, olubandakanyaivalve yokujonga ujingikunye nevalve yokukhangela yokunyusa.Iivalvu zokujonga i-Swing zine-hinge mechanism kunye nediski efana nomnyango ephumla ngokukhululekileyo kwindawo yesihlalo esithambekileyo.Ukuqinisekisa ukuba i-disc yevalve inokufikelela kwindawo efanelekileyo yendawo yokuhlala yevalve ngalo lonke ixesha, idiski yevalve iyilwe kwindlela yehinge, ukwenzela ukuba idiski yevalve ibe nendawo eyaneleyo yokujingi kwaye yenza idisc yevalve ngenene kwaye iqhagamshelane ngokubanzi isihlalo sevalve.I-disc ingenziwa ngokupheleleyo ngetsimbi, okanye ifakwe ngesikhumba, irabha, okanye i-synthetic overlays, kuxhomekeke kwiimfuno zokusebenza.Kwimeko evuleke ngokupheleleyo yevalve yokujonga ujingi, uxinzelelo lolwelo luphantse lungathintelwa, ngoko ke ukuhla koxinzelelo kwivalve kuncinci.I-disc yevalve yokukhangela i-lift ibekwe kumphezulu wokutywina wesihlalo sevalve kumzimba wevalvu.Ngaphandle kokuba idiski yevalve inokunyuka kwaye iwe ngokukhululekileyo, enye ivalve ifana nevalve yeglowubhu.Uxinzelelo lwe-fluid luphakamisa i-disc yevalve ukusuka kwindawo yokutywina yesihlalo sevalve, kunye nokubuyela ngasemva kwe-medium kubangela ukuba i-disc yevalve ibuyele kwisitulo sevalve kwaye inqumle ukuhamba.Ngokwemiqathango yokusetyenziswa, i-disc ingaba yesakhiwo sesinyithi yonke into, okanye ingaba kwifom yerabha okanye i-rubber ring efakwe kwi-disc holder.Njengevalve yeglowubhu, ukudlula kolwelo kwivalve yokujonga ujingi kukwamxinwa, ngoko ke ukuhla koxinzelelo ngevalve yokujonga i-lift kukhulu kunaleyo yevalve yokujonga ujingi, kwaye ukuhamba kwevalve yokujonga ujingi kunqabile.
