I-valve yokuhlola ibhekisela kuvalvu okuyingxenye yayo yokuvula neyokuvala iyidiski eyi-valve eyindilinga, esebenza ngesisindo sayo kanye nengcindezi ephakathi nendawo ukuze ivimbe ukugeleza emuva kwe-medium.Kuyi-valve ezenzakalelayo, eyaziwa nangokuthi i-check valve, i-valve yendlela eyodwa, i-valve yokubuya noma i-valve yokuhlukanisa.Imodi yokunyakaza kwe-disc ihlukaniswe ngohlobo lokuphakamisa kanye nohlobo lokushwiba.I-valve yokuhlola i-lift ifana nesakhiwo se-valve yembulunga, ngaphandle kokuthi ayinaso isiqu se-valve ukushayela idiski.I-medium igeleza isuka embobeni yokungena (uhlangothi olungezansi) futhi igeleza isuka endaweni yokuphuma (uhlangothi olungaphezulu).Lapho ukucindezela kwe-inlet kukhulu kunesamba sesisindo se-disc kanye nokumelana nokugeleza kwayo, i-valve ivuliwe.Ngokuphambene, i-valve ivaliwe lapho i-medium igeleza emuva.I-valve yokuhlola i-swing ine-oblique disc engakwazi ukuzungeza i-axis, futhi isimiso sayo sokusebenza sifana ne-valve yokuhlola i-lift.I-valve yokuhlola ivame ukusetshenziswa njenge-valve engezansi yedivayisi yokupompa ukuvimbela ukugeleza kwamanzi emuva.Inhlanganisela ye-valve yokuhlola kanye ne-globe valve ingadlala indima yokuhlukaniswa nokuphepha.Amavalvu okuhlola ayingxenye yamavalvu azishintshayo, futhi asetshenziswa kakhulu emapayipini ahamba ngendlela eyodwa okuphakathi, futhi avumela okuphakathi ukuthi agezele ohlangothini olulodwa ukuze kuvinjelwe izingozi.
Ama-valve okuhlola nawo asetshenziswa emigqeni ehlinzeka ngezinhlelo ezisizayo lapho ukucindezela kungase kukhuphuke ngaphezu kokucindezela kwesistimu.Ama-valve okuhlola angahlukaniswa ikakhulukazi ama-valve okuhlola ama-swing (azungezayo ngokuya phakathi nendawo ye-gravity) kanye nama-valve okuhlola aphakamisayo (ahamba e-eksisi).
Umsebenzi we-valve yokuhlola ukuvumela kuphela okuphakathi ukuthi kugeleze ohlangothini olulodwa futhi kuvimbele ukugeleza kolunye uhlangothi.Ngokuvamile lolu hlobo lwe-valve lusebenza ngokuzenzakalelayo.Ngaphansi kwesenzo sokucindezela kwamanzi okugeleza ohlangothini olulodwa, i-valve disc ivula;lapho uketshezi lugeleza ngakolunye uhlangothi, isihlalo se-valve sisebenza ngokucindezelwa kwamanzi kanye nesisindo sokuzimela se-valve disc ukuze kunqunywe ukugeleza.
Ama-valve okuhlola ahlanganisa ama-valve okuhlola ama-swing kanye nama-valve okuhlola okuphakamisa.I-valve yokuhlola i-swing ine-hinge mechanism, futhi i-disc efana nomnyango incike ngokukhululekile endaweni yesihlalo ethambekele.Ukuze uqinisekise ukuthi i-valve clack ingafinyelela endaweni efanele yendawo yokuhlala ngaso sonke isikhathi, i-valve clack yakhelwe ngendlela yamahinge, ukuze i-valve clack ibe nesikhala esanele sokushwibeka, futhi yenza i-valve ishaye i-clack ngempela futhi ixhumane nayo. isihlalo se-valve.I-disc ingenziwa ngokuphelele ngensimbi, noma ingafakwa ngesikhumba, irabha, noma isembozo sokwenziwa ensimbi, kuye ngezidingo zokusebenza.Lapho i-valve yokuhlola i-swing ivuleke ngokugcwele, umfutho we-fluid cishe awuphazamiseki, ngakho-ke ukwehla kwengcindezi nge-valve kuncane kakhulu.I-disc ye-valve yokuhlola i-lift itholakala endaweni yokuvala yesihlalo se-valve emzimbeni we-valve.Ngaphandle kokuthi i-disc ye-valve ingakhuphuka futhi iwe ngokukhululeka, yonke i-valve ifana ne-globe valve.Umfutho we-fluid wenza i-disc ye-valve iphakame endaweni yokuvala yesihlalo se-valve, futhi ukubuyela emuva kwe-medium kubangela ukuthi i-disc ye-valve ibuyele esihlalweni se-valve futhi inqamule ukugeleza.Ngokwemibandela yokusetshenziswa, i-disc ingaba yesakhiwo sensimbi yonke, noma ngesimo sephedi yerabha noma indandatho yerabha efakwe kuhlaka lwediski.Njenge-valve yokumisa, ukudlula koketshezi nge-valve yokuhlola i-lift nakho kuncane, ngakho-ke ukwehla kwengcindezi nge-valve yokuhlola i-lift kukhulu kune-valve yokuhlola i-swing, futhi izinga lokugeleza kwe-valve yokuhlola i-swing lilinganiselwe.okungajwayelekile.
Ukuhlukaniswa kwama-Check Valves
Ngokwesakhiwo, i-valve yokuhlola ingahlukaniswa i-valve yokuhlola i-lift, i-valve yokuhlola i-swing kanye ne-valve yokuhlola uvemvane.Amafomu okuxhumana alawa ma-valve okuhlola angahlukaniswa abe yizinhlobo ezine: uxhumano lwentambo, uxhumano lwe-flange, uxhumano lwe-welding kanye nokuxhumeka kwe-wafer.
Ngokusho kwezinto, i-valve yokuhlola ingahlukaniswa nge-valve yokuhlola insimbi, i-valve yokuhlola ithusi, i-valve yokuhlola insimbi engagqwali, i-carbon steel check valve kanye ne-forged steel check valve.
Ngokusho komsebenzi, i-valve yokuhlola ingahlukaniswa nge-DRVZ i-valve yokuhlola ethule, i-DRVG i-valve yokuhlola ithule, i-NRVR i-valve yokuhlola ithule, i-SFCV i-rubber disc check valve kanye ne-DDCV i-double disc check valve.
