Ivalvu yamanzi kagesi isebenza "njengesikhungo sokulawula esihlakaniphile" ezinhlelweni zokuphatha ukushisa kwezimoto zanamuhla. Ngokulawula ngokunembile indlela yokugeleza kanye nesivinini se-coolant, igcina ibhalansi yokushisa kwemoto ngaphansi kwezimo zokusebenza ezahlukahlukene.
Ngaphakathi kwesekethe yokupholisa injini, ivalvu yamanzi kagesi isebenza njenge-node yokulawula ebalulekile exhumanisa izingxenye ezifana nenjini, i-radiator, kanye ne-heater core. Umsebenzi wayo oyinhloko ukulungisa ngokunembile izindlela zokupholisa kanye namazinga okugeleza ngokusekelwe ezimweni zokusebenza kwemoto ngesikhathi sangempela. I-logic yokulawula ilandela inqubo ephelele ye-closed-loop: "ukutholwa kwesignali - ukwenziwa komyalo - impendulo yesimo."
Lapho imoto iqala ukusebenza, izingxenye ezihlanganisa inzwa yokushisa kwenjini kanye neyunithi yokulawula umoya opholile zisebenza "njengeziphetho zokuzwa," zidlulisela idatha yesikhathi sangempela—njengokushisa kwesilinda, izinga lokushisa elizungezile, kanye nezinga lokushisa elibekiwe—ku-Electronic Control Unit (ECU). Ngemva kokucubungula i-algorithm, i-ECU ithumela imiyalo yokulawula kagesi ku-valve yamanzi, icacisa ngokunembile izinga lokuvula eliqondiwe (elisekela umthethonqubo ongenazinyathelo ongu-0% kuya ku-100%) noma ukushintsha kwendlela okuhambisanayo.
Amandla okuphendula ngokushesha kwama-valve amanzi kagesi ancike ezindleleni zawo zokushayela ezihlanganisiwe.
Njengamanje, izindlela ezimbili eziyinhloko zokwenza izinto zisetshenziswa kabanzi:
- 1. Ukusebenza kwe-Solenoid: Isebenzisa amasimu kagesi ukushayela i-valve spool ngokushesha, ifinyelela izikhathi zokuphendula ezingeni le-millisecond, okwenza ifaneleke ezinhlelweni zokusebenza ezidinga ukushintshana okuvamile kokuvula/ukuvala noma ukushintsha indlela esheshayo.
- 2. Ukusebenza Kwemoto: Isebenzisa injini ye-DC ehlanganiswe nohlelo lokudlulisa igiya elinembile ukuze kufezwe ukulawula okujikelezayo. Lokhu kwenza kube nokulungiswa kokuvula okunembile kakhulu (ukunemba kokulawula kufikela ku-±1%), okulungele izimo zokusebenza ezidinga ukulawulwa kokugeleza okuzinzile.
Amavalvu amanzi kagesi athuthukiswe yiNanfeng Group asebenzisa isisombululo esithi "i-DC motor + gearbox + position sensor", efinyelela ukulawula okuqondile kokujikeleza kwamavalvu kanye nokulawulwa kokugeleza. Inzwa yesikhundla inikeza impendulo ye-voltage ehambisanayo ngokusekelwe ekhoneni lokujikeleza kwevalvu, okuqinisekisa ukunemba kanye nokuphindaphindeka ekulawuleni okuvaliwe.
Uchungechunge lomkhiqizo lunikeza ububanzi be-port obusukela ku-16 mm kuya ku-25 mm, kanye nosayizi wepayipi oxhumanisayo ongenziwa ngokwezifiso ngokwezidingo zamakhasimende. Ngokukhethekile, imodeli yobubanzi obungu-25 mm isekela ukulawula ukugeleza okusukela ku-5 L/min kuya ku-100 L/min, okuhlangabezana nezidingo ezahlukahlukene zesistimu yokuphatha ukushisa.
Ezinhlelweni ezintsha zokuphathwa kokushisa kwezimoto zamandla, ama-valve amanzi kagesi avumela ukuxhumana okuzenzakalelayo, ukunqamula, ukushintshanisa isiqondiso, kanye nokulawulwa okulinganiselayo kwe-coolant kuzo zonke izifundazwe ezahlukahlukene ngokusebenzisa amasignali okulawula kagesi. I-valve yamanzi ejwayelekile enezindlela ezintathu ihlanganisa umzimba we-valve, i-actuator, kanye ne-bracket ibe yi-compact assembly. Isebenzisa isakhiwo se-ball valve esishintsha izindlela zamanzi ngokujikeleza, nge-engeli yokuhamba engu-90°, esekela kokubili ukulungiswa okulinganiselayo kanye nokushintshana kwemodi.
Uchungechunge lwama-valve lunikeza izinzuzo ezilandelayo eziyinhloko:
- 1. Ukusebenza kahle kokuvala uphawu ngesilinganiso esincane sokuvuza
- 2. Ukunemba okuphezulu komthethonqubo ngezimpawu zokulawula eziqondile
- 3. Isivinini sokuphendula okusheshayo ngokwenziwa okunembile
- 4. Impilo yesevisi ende efanelekile kuzinhlelo zokusebenza zokushintsha imvamisa ephezulu
- 5. Ukumelana nokucindezela nokugqwala okuvumelana nezimo zemidiya eziyinkimbinkimbi
- 6. Ukusetshenziswa kwamandla okuphansi okunezici zokonga amandla
- 7. Isilinganiso esiphakeme sokuvikela amanzi esifanele izimo zokusebenza zezimoto ezidinga kakhulu
