Abstract

A cartridge relief valve is designed to meet the needs of subsea hydraulic systems. The working conditions of the deep sea hydraulic system are quite different from those of the land system, and its working characteristics need to be studied. A simulation model of the relief valve is created by Solidworks, and the leakage and deformation characteristics of the relief valve with sea depth are analysed by CFD and FEA methods respectively. The analysis shows that in the full range of sea depth, the designed relief valve internal leakage with the change of sea depth and a significant decrease in the trend; by the sea water temperature and pressure caused by the deformation of not more than 1 micron, its impact on the internal leakage is negligible, the basic cause of the change in leakage of the medium viscosity of the deep sea environment to produce a significant increase. The results of this study have a certain guiding role in the design and analysis of deep-sea relief valves.
