New national standard of hydraulic support safety valve dynamic performance test bench compared to the old standard, there is one more of a nominal flow opening, overflowing and closing characteristic test, while the current large flow safety valve dynamic performance test bench mostly only has impact properties of testing. Therefore, energy storage device was used to design for fast loading for characteristics of high flow safety valve testing bench, in order to meet the requirements of the new national standard, and the AMESim software to test rig hydraulic system simulation. The results show that the flow and pressure curve of the test system is in accordance with the new standards.
