I-valve ye-Proportional kanye nomehluko we-solenoid valve

Ama-valve alinganayo ahlukaniswe abe ama-valve alinganayo aqondile futhi ahlehlise ama-proportional valves. Umfutho womoya olungisekayo. I-valve ye-solenoid ingasebenza kuphela njengokushintsha. I-valve ye-solenoid iyi-valve engavulwa futhi ivalwe kuphela, futhi i-valve ye-proportional iyi-valve ekwazi ukulawula izinga lokuvula. Ukuyibeka kalula, i-valve yokulinganisa isetshenziselwa ukulungisa ukucindezela. Isivinini. Isenzo esijwayelekile sokuhlehla i-valve ye-solenoid

I-valve yokusiza eyinhloko ifakwe emaphethelweni aphezulu naphansi e-valve yokulawula eyinhloko, eyodwa engaphezulu neyodwa ephansi. I-valve ibeka ukucindezela okukhulu ukuze lonke uhlelo lwe-hydraulic lusebenze. Lapho ingcindezi yesistimu idlula ukucindezela kwesethi ye-valve eyinhloko yokusiza, i-valve enkulu yokukhulula ivula umjikelezo kawoyela wethangi elibuyayo ukuze lichichime uwoyela we-hydraulic ubuyele ethangini ukuze uvikele lonke uhlelo lwe-hydraulic futhi ugweme ukucindezela kukawoyela ngokweqile. I-valve enkulu yokusiza I-valve yokusiza etholakala kumzimba we-valve yokusabalalisa, indima yayo ukukhawulela ukucindezela okukhulu kwawo wonke uhlelo lwe-hydraulic ukuvikela lonke uhlelo emonakalweni, uma intwasahlobo ku-valve iphuka noma ingcindezi yokumisa iphansi kakhulu, kuzoholela ekucindezelweni kwesistimu yonke iphansi kakhulu, ngoba ukucindezelwa kwe-valve enkulu yokusiza kwenza uhlelo lonke lwe-hydraulic lungakwazi ukumisa ukucindezela okudingekayo ekusebenzeni okujwayelekile kwemishini. I-oyela ye-pump pressure eyinhloko ayikwazi ukukhuthaza umsebenzi ojwayelekile we-actuator, kuyoba khona kancane noma ngisho kungabikho isenzo semoto yonke, ngalesi sikhathi kufanele ihlolwe ukuze ithathe indawo noma ilungise i-valve yokusiza enkulu.
