I-excavator solenoid valve isethi 423-4562 i-valve ye-solenoid elinganayo

Isimiso sokusebenza kwe-electromagnetic proportional valve kanye nokutholwa:

Ukulawulwa kwe-valve kokugeleza kungahlukaniswa ngezinhlobo ezimbili:
Eyodwa ukulawulwa kokushintsha: kungaba kuvuleke ngokuphelele noma kuvalwe ngokugcwele, izinga lokugeleza likhulu noma lincane, asikho isimo esimaphakathi, esifana ne-electromagnetic evamile ngamavalvu, ama-electromagnetic reverse valves, ama-electro-hydraulic reversing valves.
Okunye ukulawulwa okuqhubekayo: imbobo ye-valve ingavulwa ngokwesidingo sanoma yiliphi izinga lokuvula, ngaleyo ndlela ilawule ubukhulu bokugeleza, ama-valve anjalo anokulawula okubhaliwe, njengama-throttle valve, kodwa futhi alawulwa nge-elekthronikhi, njenge-proportional. ama-valve, ama-servo valves.
Ngakho-ke inhloso yokusebenzisa i-valve ye-proportional noma i-valve ye-servo iwukuthi: ukufeza ukulawulwa kokugeleza ngokulawulwa kwe-elekthronikhi (yebo, ngemuva kwezinguquko zesakhiwo nakho kungafinyelela ukulawulwa kwengcindezi, njll.), njengoba kungukulawula okudonsayo, kufanele kube nokulahlekelwa kwamandla, i-servo. i-valve namanye ama-valve ahlukile, ukulahlekelwa kwawo kwamandla kukhulu, ngoba kudinga ukugeleza okuthile ukuze kugcinwe umsebenzi wesifunda samafutha okulawula isigaba sangaphambi kwesiteji.

Isimiso sokusebenza se-proportional solenoid valve

Isekelwe kumgomo we-valve yokuvala i-solenoid: lapho amandla evaliwe, intwasahlobo icindezela umgogodla ngqo esihlalweni, okwenza i-valve ivale. ikhoyili
Lapho kusetshenziswa ugesi, amandla kazibuthe kagesi akhiqizwayo anqoba amandla asentwasahlobo futhi aphakamise umongo, ngaleyo ndlela avule i-valve. I-proportional solenoid valve yenza izinguquko ezithile esakhiweni se-solenoid valve: yenza ibhalansi phakathi kwamandla asentwasahlobo namandla kazibuthe kagesi ngaphansi kwanoma iyiphi ikhoyili yamanje. Ubukhulu bekhoyili yamanje noma usayizi wamandla kazibuthe kagesi buzothinta ukushaywa kwe-plunger nokuvuleka kwevalvu, futhi ukuvuleka kwevalvu (ukugeleza) kanye nekhoyili yamanje (isignali yokulawula) kuwubudlelwane obuhle bomugqa.
Direct acting proportional valve solenoid ageleza ngaphansi kwesihlalo. I-medium igeleza isuka ngaphansi kwesihlalo, futhi isiqondiso samandla siyafana namandla kazibuthe kagesi, futhi okuphambene namandla asentwasahlobo. Ngakho-ke, kuyadingeka ukusetha amanani aphezulu kanye nobuncane bokugeleza ahambisana nobubanzi bokusebenza (ikhoyili yamanje) esimweni sokusebenza. I-proportional solenoid valve ye-Drey fluid ivaliwe (NC, uhlobo oluvamise ukuvaleka) lapho amandla ecishiwe.
