Abstract
This article presents resultsof numerical modelling,simulation andtest bench experiments of a hydraulic direct-acting relief valve was used as a safety valve.The analyzed safety valve was placed in a system consisting of a fixed-speed pump, a control valve, a hydraulic cylinder as an actuator and a second pressurevalvein the load lineused as a payload generator for the cylinder.In the first step mathematical model of the system was formulated in the form of a system of ordinary differential equations. Next, simulation model was created in Matlab/Simulink. Simulations were carried out for different valuesof the actuator payload.The obtained results includetime series of pressure, flow rate and displacement of the actuator piston. In order to confirm simulation results, a test bench was built and series of experiments were carried out. High compliance of simulation and laboratory results was obtained. It was confirmed that the proposedsolution with therelief valve used as a safety valve fulfills its task of protecting the hydraulic system from excessive pressure increase.
