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 i-valve eyinhloko yehla iye phansi ukuze ikhiphe 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.
