Analysis of Multiple Unit Valve Outlet Pressure Compensation Valve's Flow-pressure Characteristics

Jiming Zhang

Abstract

This thesis use a model of two multiple unit valve outlet pressure compensation valve which have the same structure and size but different orifice shape as research object,analysis along with spool displacement's changes,the variation of the import and export pressure and the flow,and obtains the related characteristic curve by using the Matlab programming.By comparison,research the combined type pressure compensation valve's flow-pressure characteristic,it provides certain theory instruction for multitandem valve outlet pressure compensation valve's design.
