Ivalve yolandelelwano olusebenza ngokuthe ngqo PS08-32 ivelufa yekhatriji ye-Hydraulic

Uhlalutyo olufutshane lomahluko phakathi kwevalve esebenza ngokuthe ngqo kunye nevalve esebenzayo yomqhubi
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 lutshintsha ibhalansi yamandla asebenza entliziyweni yevalve engundoqo ngokuvula kunye nokuvalwa kwevalve encedisayo (ivalve yokulinga) undoqo wevalve ukulawula ukuvuleka kunye nokuvala isenzo se-valve engundoqo. Kwisiseko sevalve engundoqo, ngenxa yokuba ivalve yokulinga isebenzisa undoqo wevalve encedisayo ukuguqula imeko yolungelelwaniso lwamandla evalve engundoqo, kunokuba ngokuthe ngqo ngoxinzelelo lokungena ukuguqula imeko yolungelelwaniso lwevalve engundoqo yamandla, kukho ngokuthe ngqo. "ngokungathanga ngqo" ngokunxulumene nodidi oluthe ngqo lwegama
