Ivalve yokukhangela ibhekisa kwivalve eyinxalenye yokuvula kunye nokuvala idiskhi yevalvu ejikelezayo, esebenza ngobunzima bayo kunye noxinzelelo oluphakathi ukuthintela ukuphuma ngasemva kwendawo ephakathi.Yivalve ezenzekelayo, ekwabizwa ngokuba yivalve yokutshekisha, ivalve yendlela enye, ivalve yokubuya okanye ivalve yokuzahlula.Imowudi yentshukumo yediski yahlulwe ngohlobo lokuphakamisa kunye nohlobo lwe-swing.Ivalve yokukhangela i-lift ifana nesakhiwo kwivalve yeglowubhu, ngaphandle kokuba ayinaso isikhondo sevalve yokuqhuba idiski.I-medium ingena kwi-port yokungena (icala elisezantsi) kwaye iphuma kwi-outlet port (icala eliphezulu).Xa uxinzelelo lwe-inlet lukhulu kunesixa sobunzima bediski kunye nokuchasana nokuhamba kwayo, i-valve ivuliwe.Ngokwahlukileyo, i-valve ivaliwe xa i-medium ihamba ngasemva.I-valve yokukhangela i-swing ine-disc ye-oblique engakwazi ukujikeleza i-axis, kwaye umgaqo wayo wokusebenza ufana ne-valve yokujonga i-valve yokuphakamisa.Ivalve yokukhangela isoloko isetyenziswa njengevalve esezantsi yesixhobo sokumpompa ukuthintela ukuphuma ngasemva kwamanzi.Ukudityaniswa kwevalve yokukhangela kunye neglobhu yeglowubhu kunokudlala indima yokhuseleko lodwa.Iivalvu zokukhangela zezodidi lweevalvu ezizenzekelayo, kwaye zisetyenziswa ikakhulu kwimibhobho enendlela enye yokuhamba phakathi, kwaye ivumela kuphela i-medium ukuba ihambe kwicala elinye ukunqanda iingozi.
Iivalve zokujonga zikwasetyenziswa kwimigca ebonelela ngeenkqubo ezincedisayo apho uxinzelelo lunokunyuka ngaphezu koxinzelelo lwenkqubo.Iivalve zokujonga zinokwahlulwa ikakhulu zibe ziivalve zokujonga ujingi (ezijikelezayo ngokweziko lomxhuzulane) kunye neevalvu zokuphakamisa iitshekhi (zihamba nge-axis).
Umsebenzi we-valve yokukhangela kukuvumela kuphela i-medium ukuba ihambe kwicala elinye kwaye ithintele ukuhamba kwelinye icala.Ngokuqhelekileyo olu hlobo lwesivalo lusebenza ngokuzenzekelayo.Ngaphantsi kwesenzo soxinzelelo lwe-fluid ehamba kwicala elinye, i-disc valve ivula;xa ulwelo luqukuqela kwicala elichaseneyo, isihlalo sevalve sisebenza ngoxinzelelo lolwelo kunye nobunzima bokuzimela bediski yevalve ukunqumla ukuhamba.
Iivalvu zokujonga ziquka iivalve zokujonga ujingi kunye neevalvu zokukhangela zokuphakamisa.Ivalve yokujonga i-swing ine-hinge mechanism, kwaye idiski efana nomnyango ingqiyame ngokukhululekileyo kumphezulu wesihlalo esithambekileyo.Ukuqinisekisa ukuba ivalve clack inokufikelela kwindawo eyiyo yomphezulu wesihlalo ngalo lonke ixesha, ivalve clack iyilwe kwindlela yehinge, ukuze ivalve ibenendawo yokujinga eyaneleyo, kwaye yenza ukuba ivalve ibe mhlophe kwaye idibane nayo. isihlalo sevalve.I-disc ingenziwa ngokupheleleyo ngetsimbi, okanye inokuthi ifakwe ngesikhumba, i-rubber, okanye i-synthetic covering kwintsimbi, kuxhomekeke kwiimfuno zokusebenza.Xa ivalve yokukhangela i-swing ivuleke ngokupheleleyo, uxinzelelo lwe-fluid luphantse lungathintelwa, ngoko ke ukuhla koxinzelelo ngevalve 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 lwenza ukuba i-disc yevalve iphakame 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 sensimbi yonke, okanye ifom yerabha okanye i-rubber ring efakwe kwi-disc frame.Njengevalve yokumisa, ukudlula kwamanzi kwivalve yokujonga i-lift nayo incinci, ngoko ke ukuhla koxinzelelo ngevalve yokukhangela i-lift likhulu kunelo levalve yokujonga i-swing, kwaye isantya sokuhamba kwevalve yokujonga i-swing silinganiselwe.inqabile.
Ukuhlelwa kweeVavu zokuHlola
Ngokwesakhiwo, ivalve yokutshekisha inokwahlulwa ibe yivalve yokujonga i-lift, ivalve yokukhangela i-swing kunye nevalve yokukhangela ibhabhathane.Iifom zokuqhagamshelwa kwezi zivalo zetshekhi zinokwahlulwa zibe ziindidi ezine: uxhulumaniso olunentambo, uxhulumaniso lwe-flange, uxhulumaniso lwe-welding kunye noqhagamshelwano lwe-wafer.
Ngokwezinto eziphathekayo, ivalve yokutshekisha inokwahlulwa ibe yintsimbi yokujonga intsimbi, ivalve yokukhangela ubhedu, ivalve yokujonga insimbi engenasici, ivalve yentsimbi yekhabhoni kunye nevalve yokukhangela intsimbi.
Ngokomsebenzi, i-valve yokutshekisha inokwahlulwa ibe yi-DRVZ i-valve yokutshekisha ethuleyo, i-DRVG i-valve yokujonga i-silent, i-NRVR i-valve yokujonga i-silent, i-SFCV i-rubber ye-disc yokujonga i-valve kunye ne-DDCV i-disc check valve kabini.
