Isingeniso somkhiqizo
I-valve ye-proportional kagesi iwukubona ukulawula ukugobhoza kokugeleza ngokulawula kwe-elekthronikhi. Idivayisi yokulawula ingcindezi kagesi iqukethe i-air inlet kanye ne-exhaust elawula i-switch solenoid valve, inzwa yokuthola ingcindezi kanye nesifunda sokulawula. Uma kukhona isignali yokufaka, i-valve ye-solenoid yokudonsa iyavulwa, i-valve ye-solenoid ephumayo ivaliwe, i-valve eyinhloko ihambisa umoya ekamelweni lomshayeli, futhi umgogodla oyinhloko we-valve wehlela phansi ukuze ukhiphe ukucindezela kwesibili.
Ukuhlelwa kwezimiso zesakhiwo
Lapho isignali yokufaka inyuswa, i-valve yokushayela engu-1 ye-solenoid valve yokulethwa komoya iyahlehliswa, futhi i-valve yomshayeli we-solenoid yokukhipha umoya isesimweni sokusetha kabusha, khona-ke ingcindezi yomoya ingena egumbini lomshayeli 5 ukusuka echwebeni le-SUP i-valve 1, nokucindezela ekamelweni lomshayeli kuyakhuphuka, futhi ukucindezela komoya kusebenza engxenyeni engenhla ye-diaphragm 2, ukuze umgogodla wokuhambisa umoya we-4 oxhunywe ne-diaphragm 2 uvulwe futhi i-valve yokukhipha 3 ivaliwe. , okuholela ekucindezelweni kokuphumayo. Lokhu kucindezela okukhiphayo kubuyiselwa emuva kumjikelezo wokulawula 8 ngokusebenzisa inzwa yokucindezela 6. Lapha, ukucindezela okukhiphayo kuqhathaniswa ngokushesha nenani eliqondiwe kuze kube yilapho lilingana nesignali yokufaka, ukuze ukucindezela okukhiphayo kushintshe ngokulingana nesignali yokufaka. . Ngenxa yokuthi awukho umshini wokuvala umlomo wombhobho, ivalvu ayizweli ukungcola futhi inokwethenjelwa okuphezulu.Ukuhlelwa kwezimiso zesakhiwo.
