I-valve ye-relay iyingxenye yesistimu ye-automotive air brake.Kuhlelo lokubhuleka lwamaloli, i-valve edluliswayo idlala indima ekufinyezeni isikhathi sokusabela kanye nesikhathi sokumisa ingcindezi.
Ivalvu edluliswayo isetshenziswa ekugcineni kwepayipi elide ukugcwalisa ngokushesha igumbi lamabhuleki ngomoya ocindezelwe ovela endaweni yokugcina umoya, njengasenqoleni noma ohlelweni lokubhuleka umahamba nendlwana.
Ngokuvamile, ama-valve e-relay ahlukene asetshenziswa.Vimbela ukusebenza ngesikhathi esisodwa kwezinhlelo zokushayela nezokupaka, kanye nokunqwabelana kwamandla kusilinda se-spring brake cylinder ne-spring brake chamber, ngaleyo ndlela kugwenywe ukugcwala ngokweqile kwezingxenye zomshini zokuhambisa ezingashaja ngokushesha futhi ziqede isilinda samabhuleki entwasahlobo.
Isimiso sokusebenza se-valve edluliswayo
I-air inlet ye-valve yokudlulisela ixhunywe endaweni yokugcina umoya, futhi i-air outlet ixhunywe ekamelweni lomoya we-brake.Lapho i-pedal ye-brake icindezelekile, ukucindezela komoya okukhiphayo kwe-valve ye-brake kusetshenziswa njengokufakwa kwengcindezi yokulawula ye-valve edluliswayo.Ngaphansi kwengcindezi yokulawula, i-valve yokudonsa iphushwa ivuleke, ukuze umoya ocindezelwe ungene egumbini lomoya webhuleki ngokuqondile ngembobo yokungena usuka endaweni yokugcina umoya ngaphandle kokugeleza nge-valve yebhuleki.Lokhu kufinyeza kakhulu ipayipi lokwehla kwamandla emali ye-brake air chamber futhi kusheshise inqubo yokwehla kwamandla emali yekamelo lomoya.Ngakho-ke, i-valve edluliselwe ibizwa nangokuthi i-valve yokusheshisa.
I-valve edluliswayo ngokuvamile isebenzisa i-valve edluliselwe ehlukile ukuvimbela ukusebenza ngesikhathi esisodwa kwesistimu yokushayela neyokupaka, kanye namandla agqagqene kusilinda se-spring brake cylinder ne-spring brake chamber, ngaleyo ndlela kugwenywe ukugcwala ngokweqile kwezingxenye zokuhambisa ngomshini ezingashaja futhi ziqede amandla ngokushesha. i-spring brake cylinder.Kodwa-ke, kungase kube nokuvuza komoya, okuvame ukubangelwa ukuvaleka kancane kwamavalvu okungenisa noma okukhipha umoya, futhi lokhu kubangelwa ukulimala kwezakhi zokuvala noma ukuba khona kokungcola nezindaba zangaphandle.Ukuqaqa nokuhlanza noma ukushintshwa kwezinto zokuvala kungaxazulula inkinga.
