I-Balance Valve Sakhiwo kanye Nemigomo Yokusebenza

I-Hydraulic Balance Valve ivumela uwoyela ukuthi ageleze ngokukhululeka kusuka ePort 2 kuya ePort 1. Singabona kusuka ku-Port Port

Ukugeleza okuvela ePort 1 kuya ePort 2 kuvinjelwe kuze kube yilapho ingcindezi yePilot Port ifinyelela inani elithile futhi iBlue Spool ihanjiswe kwesobunxele ukuvula itheku le-Valve ukuze uphumelele echwebeni 2.

Itheku livale lapho ingcindezi yokushayela inganele ukuvula i-spool eluhlaza okwesibhakabhaka. Ukugeleza kusuka echwebeni 1 kuya ePort 2 kuyanqunywa.

Uphawu lwemigomo ye-valve esele lumi ngokulandelayo;

Ngokuhlangana kwe-halve ye-sequence ne-valve esele elibangeni elingezansi, amasu amaningi okulawula ukulinganisa kwamanani amakhulu okugeleza angatholakala. Ngasikhathi sinye, uma kusetshenziswa ama-valves alinganiselayo esiteji sokushayela, ukuhlanganiswa okuhlukahlukene okuhlukahlukene kungatholakala. Lolu hlobo lweSikimu Sokulawula singakhulisa kakhulu umqondo wokuqamba.

I-Balancing Valve njengokucindezela okulinganise ukuxhumeka kwe-valve valve parallel ukuxhumana okufanayo:

Izinqubo zokulawula ezahlukahlukene zitholakala ngama-valves alinganiselayo afanayo anezilinganiso ezihlukile zokushayela izindiza. Ama-valves alinganisa amabili aqondisayo kuMdwebo 4 ahlanganisa ukulawulwa kwangaphambi. Umthwalo ongemuhle yi-valve yokushayela elawula isilinganiso sokuhlubuka kwengcindezelo ye-2: 1 iyasebenza. Lapho umthwalo uqondile, okungukuthi, lapho ingcindezi engeniswe iphakeme kunengcindezi yokulayisha, i-valve yesibili elawulwa ngaphambili izosebenza, futhi umehluko wokulawula uphakeme kuno-10: 1. Ukuze uvikele i-valve ye-10: 1 yokuvula kusuka endaweni engemihle yomthwalo, kuzoba nengcindezi ekhawulelayo ye-valve r (empeleni i-valve echichimayo). Lapho ingcindezi ye-inlet iphezulu, ingcindezi ekhawulela i-valve r iyavula, futhi i-valve yebhalansi ye-10: 1 ithola isibonakaliso sokucindezela umshayeli ukuze ivule.

Ukusebenza okuhlukile kokulawulwa kungatholakala ngokulungisa ingcindezi yokukhawulela i-valve R.
