Izesekeli ze-Excavator 323-7898 rotary priority pilot valve

Isimiso sokusebenza se-valve ye-solenoid

Ukulandelela umlando we-valve ye-solenoid, kuze kube manje, i-valve ye-solenoid ekhaya nakwamanye amazwe ihlukaniswe izigaba ezintathu ngokomthetho (okungukuthi: ukusebenza okuqondile, isinyathelo ngesinyathelo esiqondile, umshayeli-osebenza), Ngokusho komehluko isakhiwo se-valve disc, impahla kanye nesimiso, ihlukaniswe yaba izigaba eziyisithupha (isakhiwo se-diaphragm esisebenza ngokuqondile, isakhiwo se-diaphragm yesinyathelo, isakhiwo somshayeli we-diaphragm, isakhiwo se-piston esisebenza ngokuqondile, isakhiwo se-piston isinyathelo, isakhiwo se-piston piston).

(1) I-valve ye-solenoid esebenza ngokuqondile
Isimiso: Uma unamandla, amandla kazibuthe kagesi akhiqizwa ikhoyili kagesi aphakamisa ingxenye yokuvala esihlalweni, futhi ivalvu iyavuleka;Lapho amandla ecishiwe, amandla kazibuthe kagesi ayanyamalala, amandla asentwasahlobo acindezela ingxenye yokuvala esihlalweni, futhi i-valve ivaliwe.
Izici: Ingasebenza ngokujwayelekile ngaphansi kwe-vacuum, ingcindezi engalungile kanye nengcindezi ye-zero, kodwa ngokuvamile ububanzi abudluli ku-25mm.

(2) isinyathelo ngesinyathelo esiqondisa i-solenoid valve
Isimiso: Kuyinhlanganisela yesenzo esiqondile kanye nesimiso somshayeli, lapho umehluko we-inlet ne-outlet pressure ≤0.05Mpa, amandla, amandla kazibuthe kagesi aqonde ku-valve encane yomshayeli kanye nezingxenye zokuvala eziyinhloko ziphakamisa ngokushintshana, i-valve iyavuleka.Lapho umehluko we-inlet ne-outlet pressure> 0.05Mpa, lapho amandla evuliwe, amandla kazibuthe avula kuqala i-valve encane yomshayeli, ingcindezi egunjini elingezansi le-valve eyinhloko iyenyuka, nokucindezela ekamelweni eliphezulu kuyehla, ukuze umehluko wengcindezi usetshenziselwa ukusunduza i-valve eyinhloko phezulu;Lapho amandla ecishiwe, i-valve yokushayela kanye ne-valve eyinhloko zisebenzisa amandla asentwasahlobo noma ukucindezela okuphakathi ukusunduza ingxenye yokuvala bese yehla ukuze ivale i-valve.
Izici: Umahluko we-zero pressure noma i-vacuum, ingcindezi ephezulu ingasebenza ngokwethembeka, kodwa amandla makhulu, adinga ukufakwa okuqondile.
