1. Ts'ebetso ea Ts'ebetso ea Motlakase
Matla a ho khanna a valve ea solenoid a tsoa ho coil ea solenoid. Ha khoele e felloa ke-matla, ntlha ea valve e boemong ba eona ba pele (hangata e hlokomeloa ke ho roala pele nakong ea selemo), 'me tsela ea mokelikeli e ka ba e butsoe kapa e thibiloe ka ho sa feleng. Mohlala, ka tsela e tobileng-e sebetsang, 2/2-valve ea tsela, konokono ea li-valve e thibela likou tsa oli ha e felloa ke matla, e thibela mokelikeli oa haeteroliki ho phalla. Ha coil e hokahane le mohloli oa matla oa DC kapa oa AC, hona joale ho hlahisa matla a khoheli ka har'a coil. Matla ana a khoheli a hulela konokono ea valve ho ea ho solenoid, a hlola khanyetso ea selemo mme ka hona a fetola khokahano ea boema-kepe ba oli (mohlala, ho bula tsela ho lumella ho phalla ha mokelikeli).
Bakeng sa -li-valve tsa solenoid tse sebetsang tse sebetsang (tse loketseng-mesebetsi e phahameng ea khatello,{2}}ea phallo e phahameng), e nyenyane, e tobileng{3}}vallou e sebetsang ea solenoid (valafo ea sefofane) e laola khatello ea oli ea sefofane sephakeng se seholo. Ha belofo ea sefofane e matlafatsoa, khatello ea oli ea mofofisi e tsamaisa karolo e ka sehloohong ea valve, kahoo e bula, e koala kapa e fetola tsela e kholo ea oli. Sebopeho sena se fokotsa matla a motlakase a hlokahalang ho kenya letsoho ka kotloloho mokokotlong o moholo oa li-valve, ka hona, ho eketsa lebelo la khatello ea valve.
2. Valve Core Movement le Taolo ea Mokelikeli
Boemo ba mokokotlo oa valve ka ho toba bo khetholla tsela ea ho phalla ha metsi a hydraulic. Ka mohlala, ho nka maemo a mararo-,{2}}way solenoid e mene e le mohlala:
• Boemo ba ho se nke lehlakore (bo tloaelehileng): Ka bobeli li-coil tsa solenoid li feletsoe-matla, konokono ea li-valve e bohareng ba nako ea selemo, sebaka sa ho kena ha oli le likou tsa ho khutlisa oli li hokahane, liphaposi tse peli tsa actuator (joalo ka hydraulic cylinder) li koetsoe, 'me sistimi e lula e eme.
• Sebaka se ka ho le letshehadi (coil A e matlafaditswe): Khoele e ka ho le letshehadi ya solenoid e matlafatswa, e etsa hore mothapo wa valve o ye ka ho le letshehadi. Mokotla oa oli P o hokahana le kamore ea A actuator e se nang molamu, 'me kamore ea molamu B e hokahana le boema-kepe ba ho khutlisa oli T, e sutumelletsa actuator ka lehlakoreng le leng.
• Sebaka se nepahetseng (coil B e matlafalitsoe): Khoeli e nepahetseng ea solenoid e matlafatsoa, e etsa hore mokokotlo oa valve o tsamaee ka ho le letona. Mokotla oa oli P o hokahana le kamore e se nang rod B, 'me kamore e se nang rod A e hokahana le boema-kepe ba ho khutlisa oli T, e leng se etsang hore actuator e tsamaee ka lehlakoreng le leng.
Mokelikeli o phalla ka har'a sebaka se lumellanang hantle pakeng tsa mokokotlo oa valve le 'mele oa valve. Boholo ba sebaka sa ho kolobisa bo ama ka kotloloho ho lutla le ho lahleheloa ke khatello, kahoo{1}}mechining e nepahetseng e phahameng (e kang ho sila le ho bentša) hoa hlokahala ho netefatsa ho koala le ho phalla hantle.
3. Litšobotsi tsa Phetoho ea Matla le Karabelo
Mokotla oa valve ea solenoid ke mokhoa oa ho fetola matla a motlakase hore e be matla a mochini: matla a motlakase a khanna coil ea motlakase ho hlahisa matla a khoheli, a fetoloang hore e be phallo ea mantlha ea valve, e qetelle e fetola tsela ea matla a mokelikeli (khatello le phallo). Lebelo la eona la ho arabela le lekanyelitsoe ke nako ea ho hlasimolla ea li-electromagnetic coil (hangata li-milliseconds) le inertia ea mochini oa konokono ea valve. Ka tlas'a-maemo a ho sebetsa a khafetsa, moralo o ntlafalitsoeng oa coil (joalo ka ho sebelisa pulse-width modulation (PWM) control) ho hlokahala ho fokotsa ho lieha.
