Hydraulic balance valve Excavator hydraulic cylinder valve core CBCH-LJN

Ivalve esebenza ngokuthe ngqo kunye nevalve yokulinga yahlulwe ngokwesakhiwo sevalve, owona mahluko usisiseko phakathi kwezi zimbini kukuba ivalve esebenza ngokuthe ngqo inomzimba omnye, kwaye ivalve yokulinga inemizimba emibini. Omnye ngumzimba wevalvu ophambili kwaye omnye ngumzimba wevalvu encedisayo. Phakathi kwabo, i-valve engundoqo ayifani kakhulu nohlobo olusebenzayo oluthe ngqo kwisakhiwo; Ivalve encedisayo ikwabizwa ngokuba yivalve yokulinga, eneneni ilingana nevalve esebenza ngokuthe ngqo.
Ngokomgaqo, ukufana phakathi kwee-valve ezisebenza ngokuthe ngqo kunye ne-pilot-operated valves kukulawula ukuvulwa kunye nokuvalwa kwe-valve core ngokungalingani kwamandla asebenza entliziyweni ye-valve engundoqo (kubandakanywa uxinzelelo lwe-oyile kunye ne-spring force, njl. ). Uhlobo olusebenzayo oluthe ngqo kukuba ioli yoxinzelelo (ioli) yenkqubo isebenza ngokuthe ngqo entliziyweni ye-valve engundoqo kunye nokulinganisela kunye neminye imikhosi (njengamandla asentwasahlobo) ukulawula ukuvulwa kunye nokuvala isenzo se-valve core; Uhlobo lwe-pilot lutshintshwa ngokuvula kunye nokuvala i-valve core ye-valve encedisayo (ivalve yokulinga)
Ibhalansi yamandla entliziyweni yevalve engundoqo isetyenziselwa ukulawula isenzo sokuvula kunye nokuvala iziko le-valve engundoqo. Kwintliziyo yevalve engundoqo
Umzekelo, ngenxa yokuba ivalve yokulinga isebenzisa undoqo wevalve encedisayo ukuguqula ibhalansi yamandla evalve engundoqo, endaweni yokuba
Ngqo ngoxinzelelo lweoyile yokutshintsha ibhalansi yamandla evalve yevalve engundoqo, ngoko kukho uhlobo oluthe ngqo kunye nohlobo oluthe ngqo lwe "indirect" ebizwa.
