description | The utility model discloses a device for eliminating oil pressure fluctuation of a high-pressure hydraulic valve, which comprises a hydraulic oil supply oil way and a hydraulic oil return oil way, the hydraulic oil supply oil way is divided into a first branch and a second branch after being communicated with the hydraulic valve, the first branch and the second branch are respectively communicated with two output ends of the hydraulic valve, and the second branch is further communicated with a third branch and more branches. The first branch and the third branch are both communicated with a hydraulic oil return oil way to form a loop, the loop is communicated with a first energy accumulator, the first energy accumulator can store vapor and liquid in the loop, an energy accumulator skid serves as a constant-pressure supplementing oil source and is installed close to an impact point, arrangement of a high-pressure hydraulic oil pipeline and fixing of a pipeline support are optimized, and the energy accumulator |
