I-hydraulic balance valve Excavator hydraulic cylinder spool CXHA-XAN

Isakhiwo se-valve yebhalansi kanye nesimiso sokusebenza

I-valve yebhalansi ye-hydraulic ivumela uwoyela ukuthi ugeleze ngokukhululeka ukusuka ku-port 2 ukuya ku-port 1. Singabona kusukela kumdwebo wesakhiwo phezulu esithombeni esingezansi ukuthi uma ukucindezela kukawoyela kwe-port 2 kuphezulu kunokwembobo 1, i-spool ingxenye eluhlaza iya echwebeni 1 ngaphansi kokushayela kwengcindezi ye-liquid, futhi i-valve yokuhlola ivuliwe, futhi uwoyela ungageleza ngokukhululekile ukusuka ku-port 2 kuya ku-port 1.

Ukugeleza kusuka kumbobo 1 kuya kutheku 2 kuvinjiwe kuze kube yilapho ukucindezela kwembobo yokushayela kufinyelela kunani elithile futhi i-spool eluhlaza okwesibhakabhaka ihanjiswa kwesokunxele ukuze kuvulwe imbobo yevalvu ukuze uwoyela ukwazi ukugeleza ukusuka ku-port 1 ukuya ku-port 2.

Imbobo iyavala lapho ukucindezela komshayeli kunganele ukuvula i-spool eluhlaza okwesibhakabhaka. Ukugeleza kusuka ku-port 1 kuya ku-port 2 kunqanyuliwe.

Uphawu lwesimiso se-valve yebhalansi lumi kanje;

Ngokuhlanganiswa kwe-valve yokulandelana kanye ne-valve yebhalansi esithombeni esingezansi, izinhlelo eziningi zokulawula ibhalansi zamazinga amakhulu okugeleza zingafinyelelwa. Ngesikhathi esifanayo, uma ama-valve ebhalansi ahlukene asetshenziswa esigabeni sokuhlola, inhlanganisela yokulawula ehlukahlukene ingafinyelelwa. Lolu hlobo lwesikimu sokulawula lungakhulisa kakhulu umbono wokuklama.

I-valve yokulinganisa njengoxhumano oluhambisanayo lwe-valve yokulinganisa i-valve:

Izinqubo ezihlukene zokulawula zenziwa ngama-valve okulinganisa ahambisanayo anezilinganiso ezihlukene zomshayeli. Amavalvu okulinganisa amabili asebenza ngqo kuMfanekiso 4 ahlanganisa ukulawulwa kwangaphambili. Umthwalo ongemuhle yivalvu yokushayela elawula isilinganiso sokucindezela okuhlukile esingu-2:1 sicushiwe. Uma umthwalo ulungile, okungukuthi, lapho ingcindezi endaweni yokungena iphakeme kunokucindezela komthwalo, i-valve yesibili yokulinganisa elawulwa ngaphambilini izosebenza, futhi umehluko wengcindezi yokulawula uphakeme kune-10: 1. Ukuze uvimbele i-valve yebhalansi engu-10:1 ukuthi ingavuleki endaweni yomthwalo ongemuhle, kuzoba ne-valve yokunciphisa ukucindezela engu-R (empeleni i-valve yokuchichima). Uma umfutho we-inlet uphezulu, i-valve engu-R ekhawulela ukucindezela iyavuleka, futhi i-valve yebhalansi engu-10:1 ithola isignali yengcindezi yomshayeli ukuze ivuleke.

Ukusebenza kokulawula okuhlukile kungatholwa ngokulungisa i-valve yokunciphisa ingcindezi R.
