The filling valve and relief valve are core components to ensure the rapid filling of fluid and the stable pressure unloading in the large press. To further improve the filling speed of the filling valve with the function of pressure relief, a novel high-flow filling valve based on compound flow channels and multi-stage hydraulic resistance was designed. The mathematical model and simulation model of the structure of multi-stage hydraulic resistance based on AMESim were established, the influence rules of the critical parameters of the annular hydraulic resistance on pressure relief characteristics were analyzed. The multi-stage annular structure can achieve multi-stage pressure relief. The numerical analysis model of the filling valve with detailed structures based on Fluent was built. The curves of multi-stage pressure unloading based on the pressure contours and velocity contours show that the designed valve has good multi-stage relief characteristics, and the filling rapidity and unloading stability can also be balanced well. Comparing to the traditional single-channel filling valve, the valve with compound flow channels can significantly improve the filling rate according to the numerical analysis in Fluent. The novel designed hydraulic component for filling has the function of high-flow filling and steady pressure unloading. Therefore, it has good engineering application value.
