The pressure relief component is set in the reasonable part of the building, so that when the indoor explosion occurs, thepressure relief component can instantly release the critical pressure, guide the orderly release of the explosive force,reduce the impact on other parts in the explosion process, and at the same time, by controlling the quality and propertiesof the explosive fragments, it can effectively reduce the occurrence of personal injury and property loss caused by theexplosive shock and the explosive fragments Probability.
