The invention relates to the field of pressure relief valve manufacturing, and provides a pressure relief valve accelerator. The pressure relief valve accelerator aims at solving the problem that a pressure relief valve cannot achieve pressure relief in time in the prior art. The pressure relief valve accelerator comprises a body, a piston, a blocking piece and a control pipe. Liquid flows into the control pipe with the small inner diameter and then flows into a first cavity through the control pipe, the piston is pushed to drive the blocking piece to open a first channel under the action of the pressure of the liquid along with increase of the volume of the liquid in the first cavity, and then the first channel is opened. Due to the fact that the inner diameter of the control pipe is small, under the condition of the same liquid pressure intensity, the pressure of the liquid in the control pipe with the small inner diameter is relatively large, the liquid can flow into the first cavity fast, the piston is pu
