Ivalve ye-hydraulic balance valve Excavator hydraulic cylinder valve core NFED-LHN

Xa i-valve yokunceda ngokubanzi isebenza, ilungiswa ngokupheleleyo kwaye ilawulwa yingcinezelo yasentwasahlobo. Iyakwazi ukulungelelanisa uxinzelelo lweoli ye-hydraulic ngoxinzelelo. Ngokuqhelekileyo, ukuba uxinzelelo lweoli ye-hydraulic luncinci kunoxinzelelo olufunekayo kumsebenzi, i-spool igxininiswe yintwasahlobo ngeli xesha kwaye ifakwe kwi-attachment inlet ye-oyile ye-hydraulic. Kodwa xa uxinzelelo lweoyile ye-hydraulic lukhulu kunoxinzelelo oluvumelekileyo emsebenzini, ngamanye amazwi, xa uxinzelelo lukhulu kunomthombo, i-spool iqhutywe ngokwemvelo ngeoli ye-hydraulic, kwaye ioli ye-hydraulic iya kugeleza kwaye qukuqela ukuya kwitanki.

Xa uxinzelelo lweoyile ye-hydraulic lukhula ngokuthe ngcembe, i-spool nayo iya kunqunyulwa ngokuthe ngcembe. . Ngeli xesha, i-oyile ye-hydraulic ihamba ngevalve yokukhulula ukuya kwitanki efanelekileyo yokuhamba iya kunyuka ngokuthe ngcembe, xa uxinzelelo lweoyile ye-hydraulic luncitshiswa ukuba lulingane okanye lungaphantsi koxinzelelo lwasentwasahlobo, i-spool iya kuwa ngokwendalo ukutywina i-inlet ehambelana nayo. ioli yehydraulic.
Ukukhutshwa kweoli ye-hydraulic ngepompo ye-oyile jikelele inexabiso elimiselweyo loxinzelelo, kwaye uxinzelelo oluhambelanayo lweoyile ye-hydraulic esetyenziswa yi-cylinder esebenzayo ehambelanayo ngokuqhelekileyo incinci kakhulu kunokukhutshwa koxinzelelo ngepompo yeoli. Ngeli xesha, siya kubona ukuba xa umsebenzi uqhelekile, kuya kubakho ioyile yehydraulic equkuqela kwitanki ngesixhobo sevalvu yokukhulula. Oku kunokuqinisekisa ukuba i-cylinder ye-hydraulic inoxinzelelo oluqhelekileyo lokusebenza.
