With the development of science and technology and the construction of offshore oil platforms, the optimization of water control systems for large hydraulic press has become an inevitable trend in marine engineering research. Combining with related theories of mechanical engineering and marine engineering, and numerical analysis method, this paper adopted the finite element analysis software ABAQUS to establish numerical models for the water inlet and outlet valves of the hydraulic press, it simulated and analyzed the flow field state of the valve port under different fluid pressures and spool displacements, thereby studying the structural characteristics and optimization of the hydraulic press water control system. The results showed that when the fluid past through the inlet valve, local low-pressure zones appeared at the inlet valve port, and the low-pressure zones inside the inlet valve port increased with the increase of the spool displacement; the fluid pressure had a certain degree influence on the flow performance of the inlet valve, under the same spool displacement, the fluid flow increased with the displacement of the inlet valve spool; the speed increase of fluid flow past through the outlet valve gradually increased with the increase of the displacement of the outlet valve spool, the fluid pressure of the outlet valve increased first and then decreased as the displacement of the spool increased. This study provided technical support for the application of hydraulic press in marine engineering and laid a theoretical foundation for the structural optimization of hydraulic press.
