[0026] In the embodiment of the utility model, the shape between the two ends of first buffer hole 301 and second buffer hole 302 is corrugated, and the positions of first buffer hole 301 and second buffer hole 302 are staggered; since the shape of the hole is hexagonal and corrugated, when pressure passes through the holes, it will be constantly reflected and refracted between the hole walls, change direction multiple times, and realize energy dispersion.

[0027] In the embodiment of the utility model, the corners of protection plate 4 are fixedly provided with connecting buckles 401, and the side of buffer plate 3 combined with protection plate 4 is provided with connecting grooves 303 combined with connecting buckles 401, connecting buckle 401 includes a circular block, a tapered clamping block is fixedly arranged on the top of the circular block, and the diameter of the clamping block is greater than the diameter of the circular block; the unique circular block and tapered clamping block design of connecting buckle 401 can improve the limiting strength after being connected with connecting groove 303, and ensure that protection plate 4 will not easily fall off when bearing pressure.
[0028] Working principle: the embodiment provides an explosion-proof pressure relief plate for petrochemical industry, when explosion occurs in petrochemical industry environment, strong pressure wave is generated, the outer corrugated metal plate 1 is first affected.
