Abstract
To satisfy the demand of inlet pressure for air powered engine, it is necessarily to design control valve. The design idea of control valve was proposed, and the models for simulation design were established. These models are air bottle state model, open area model of control valve, spool dynamic model and shape calculation model of characteristic vent. Based on these models, the joint simulation and the experiment test have been done. The result shows that the designed control valve can provide required inlet pressure for air powered engine and satisfy the work demand well. The result of the experiment verifies the rationality and validity of the simulation design, and the method can be used in the design of the congener valve.
