In this paper, the research method of CFD computational fluid dynamics is used. The software Fluent is used to simulate the circular and square orifice structures of the relief valve spool. It is found that the fluid pressure distribution of the square orifice is more uniform. At the same time, the valve comprehensive test bench was used to test the starting pressure and closing flow rate of a certain type of relief valve structure. The results show that the working pressure of the relief valve with 0.3 mm wide square orifice spool orifice is more stable than the circular structure with the same opening area, and the opening characteristics are improved.
