Abstract: A cartridge one-way relief valve is proposed, which has the characteristics of direct detection. The cartridge valve has the features of small override pressure and high precision of control pressure. To analyze the mechanism of the regulating property, a transfer function is established according to the theoretical analysis of the relief process and the corresponding key parameters are qualitatively analyzed. The HCD simulation model of the relief valve is established using AMESim software. The effects of the key parameters on the dynamic characteristics and the steady-state performance of the cartridge one-way relief valve are quantitatively analyzed. Theoretical analysis and simulation results indicate that the direct detection characteristic forms the interstage negative feedback, which can effectively reduce the steady-state override pressure. Furthermore, adjusting the size of the annular gap helps to improve the dynamic characteristics of the relief valve, and adjusting the mandrel end surface area helps to improve the steady-state characteristics of the relief valve. The one-way valve with this structure helps oil supply.

Key words: turn and control of fluid, relief valve, direct detection, transfer function, AMESim simulation
