Ivalvu yamanzi yombane isebenza njenge "indawo yokulawula ekrelekrele" kwiinkqubo zolawulo lobushushu beemoto zanamhlanje. Ngokulawula ngokuchanekileyo indlela yokuhamba kunye nesantya se-coolant, igcina ibhalansi yobushushu besithuthi phantsi kweemeko ezahlukeneyo zokusebenza.
Ngaphakathi kwisekethe yokupholisa injini, ivalvu yamanzi yombane isebenza njenge-node yolawulo ebalulekileyo edibanisa izinto ezifana ne-injini, i-radiator, kunye ne-heater core. Umsebenzi wayo ophambili kukulungisa ngokuchanekileyo iindlela zokupholisa kunye namazinga okuhamba kwamanzi ngokusekelwe kwiimeko zokusebenza kwesithuthi ngexesha langempela. Ingqiqo yolawulo ilandela inkqubo epheleleyo ye-closed-loop: "ukufunyanwa kwesignali - ukuphunyezwa komyalelo - impendulo yesimo."
Xa imoto iqala ukusebenza, izinto eziquka isenzi sobushushu benjini kunye neyunithi yokulawula umoya opholileyo zisebenza njenge "terminals zokuva," zithumela idatha yexesha langempela-njengobushushu besilinda, ubushushu obuphakathi, kunye nobushushu obumiselweyo-kwiYunithi yoLawulo lwe-Electronic (ECU). Emva kokucubungula i-algorithm, i-ECU ithumela imiyalelo yokulawula umbane kwivalvu yamanzi, ichaza ngokuchanekileyo nokuba linqanaba lokuvula elijoliswe kulo (elixhasa ummiselo ongenamagxathu ukusuka kwi-0% ukuya kwi-100%) okanye ukutshintsha kwendlela ehambelanayo.
Amandla okuphendula ngokukhawuleza kweevalvu zamanzi zombane axhomekeke kwiinkqubo zazo zokuqhuba ezidibeneyo.
Okwangoku, iindlela ezimbini eziphambili zokulinganisa umbane zisetyenziswa ngokubanzi:
- 1. I-Solenoid Actuation: Isebenzisa amasimi e-electromagnetic ukuqhuba i-valve spool ngokukhawuleza, ifikelela kumaxesha okuphendula kwinqanaba le-millisecond, okwenza ifaneleke kwizicelo ezifuna ukutshintshwa rhoqo kokuvula/ukucima okanye utshintsho lwendlela ekhawulezayo.
- 2. Ukusebenza kweMoto: Isebenzisa i-DC motor edityaniswe nenkqubo yokudlulisa izixhobo ezichanekileyo ukuze kufezekiswe ulawulo olujikelezayo. Oku kwenza kube lula ukulungelelanisa ukuvulwa okuchanekileyo (ukuchaneka kolawulo ukuya kuthi ga kwi-±1%), okulungele iimeko zokusebenza ezifuna ulawulo oluzinzileyo lokuhamba komoya.
Iivalvu zamanzi zombane eziphuhliswe yiNanfeng Group zamkela isisombululo esithi "i-DC motor + gearbox + position sensor", zifezekisa ulawulo oluchanekileyo lokujikeleza kwevalvu kunye nolawulo lokuhamba. I-position sensor inika impendulo yevolthi ehambelanayo ngokusekelwe kwi-engile yokujikeleza kwevalvu, iqinisekisa ukuchaneka kunye nokuphindaphinda kulawulo oluvaliweyo.
Olu luhlu lwemveliso lubonelela ngobubanzi bezibuko obuqala kwi-16 mm ukuya kwi-25 mm, kunye nobukhulu bepayipi eqhagamshelwayo obunokulungiselelwa ngokweemfuno zabathengi. Ngokukodwa, imodeli yobubanzi obuyi-25 mm ixhasa ulawulo lokuhamba kwamanzi oluqala kwi-5 L/min ukuya kwi-100 L/min, oluhlangabezana neemfuno ezahlukeneyo zenkqubo yolawulo lobushushu.
Kwiinkqubo ezintsha zolawulo lobushushu bezithuthi zamandla, iivalvu zamanzi zombane zivumela uqhagamshelo oluzenzekelayo, ukunqunyulwa, ukutshintsha indlela, kunye nokulawulwa ngokulinganayo kwe-coolant kwiisekethe ezahlukeneyo ngokusebenzisa imiqondiso yokulawula ye-elektroniki. Ivalvu yamanzi eqhelekileyo eneendlela ezintathu idibanisa umzimba wevalvu, i-actuator, kunye ne-bracket kwindibano encinci. Isebenzisa isakhiwo sevalvu yebhola esitshintsha iindlela zamanzi ngokujikeleza, nge-engile yokuhamba ye-90°, exhasa uhlengahlengiso olulinganayo kunye nokutshintsha kwendlela.
Olu luhlu lweevalvu lubonelela ngezi nzuzo zilandelayo ziphambili:
- 1. Ukusebenza kakuhle kokutywina kunye nesantya esincinci sokuvuza
- 2. Ukuchaneka komthetho ophezulu kunye neempawu zolawulo oluthe tye
- 3. Isantya sokuphendula ngokukhawuleza kunye nokusebenza ngokuchanekileyo
- 4. Ubomi benkonzo ende bufanelekile kwizicelo zokutshintsha rhoqo
- 5. Uxinzelelo kunye nokumelana nokugqwala okuguquguqukayo kwiimeko zeendaba ezinzima
- 6. Ukusetyenziswa kwamandla okuphantsi kunye neempawu zokonga umbane
- 7. Uvavanyo oluphezulu lokungena kwamanzi olufanelekileyo kwiimeko zokusebenza kweemoto ezifuna amandla
