Indima yevalve ye-hydraulic balance

I-valve yokulinganisa i-hydraulic isetyenziselwa ukulawula ukuhamba kweoli kwi-hydraulic system okanye ukulungelelanisa uxinzelelo kunye nokuhamba kwayo, ngoko inokwahlulwa ibe ngamacandelo amathathu: i-valve yokulinganisa i-valve, i-valve yokulinganisa i-valve kunye ne-valve balance balance. Ivalve enemilo efanayo ingaba nemisebenzi eyahlukeneyo ngenxa yendlela eyahlukileyo yokusebenza. Ivalve yokulinganisa uxinzelelo kunye nevalve yokulinganisa ukuhamba ilawula uxinzelelo kunye nokuhamba kwenkqubo ngesenzo se-throttling yecandelo lokuhamba, ngelixa i-valve yokulinganisa isalathiso ilawula ukuhamba kwe-oyile ngokutshintsha umjelo wokuhamba. Oko kukuthi, nangona kukho iindidi ezahlukeneyo zeevalvu ze-hydraulic balance, zisagcina amanqaku asisiseko afanayo. Umzekelo:

(1) Ngokwesakhiwo, zonke iivalvu zenziwe ngumzimba wevalvu, i-spool (ivalve ejikelezayo okanye ivalve yesilayidi), kunye nezinto kunye namalungu (anje ngemithombo kunye nozibuthe wombane) eziqhuba isenzo se-spool.
(2) Ngokomgaqo wokusebenza, ubudlelwane phakathi kobukhulu bokuvula kuzo zonke iivalvu, umahluko woxinzelelo phakathi kwendawo yokungena kunye nokuphuma kwevalvu kunye nokuhamba ngevalvu ihambelana nefomyula yokuhamba kwezibuko, kodwa iiparamitha ezilawulwa iivalve ezahlukeneyo zahlukile.

Okwesibini, iimfuno ezisisiseko zevalve ye-hydraulic balance
(1) Isenzo esibucayi, ukusetyenziswa okuthembekileyo, impembelelo encinci kunye nokungcangcazela ngexesha lomsebenzi.
(2) Ukulahleka koxinzelelo lokuhamba kweoli kuncinci.
(3) Ukusebenza kakuhle kokutywinwa.
(4) Isakhiwo esiqinileyo, ukufakwa lula, ukulungiswa, ukusetyenziswa, ukugcinwa, ukuguquguquka.
