Explosion test pressure relief device

The invention relates to the technical field of test devices, and discloses an explosion test pressure relief device which can give out alarm sound to prompt test workers. The pressure value can be read, and the pressure can be adjusted; before the explosion test of the detected product is confirmed, the current explosion pressure value is calculated, and then the device is adjusted to the corresponding pressure value according to the pressure value; when a detected product is detected to be unqualified and explosion propagation occurs, the device can be started, pressure generated by explosion of an explosion test tank is discharged through the device, the explosion tank is protected against damage caused by too large pressure, and the maximum effect is that life and property safety of detection workers is protected; compared with a disposable explosion venting sheet, the explosion venting sheet can be used for multiple times, the testing cost is effectively reduced, and the working intensity of workers is r
