爆炸发生后的瞬间，其中心的超高压空气团扩散，猛烈冲击其周围的介质形成爆炸冲击波，这种爆炸冲击波对舰船外部及内部通风设施具有强大的破坏力和杀伤力。本文通过对爆炸冲击波作用原理的研究，提出舰船集体防护系统滤毒通风装置前实现爆炸冲击波防护的解决方案，研制成功了能瞬间快速关闭的通风阀门（HFB系列抗冲击波阀），能够有效隔离冲击波的进入，保证滤毒通风装置不被破坏。产品经过大量的模拟冲击波试验验证，满足了滤毒通风装置对爆炸冲击波的隔离要求。
Immediately after the explosion, the ultra-high pressure air mass in the center diffused and violently impacted the surrounding medium to form an explosion shock wave. This explosion shock wave had a strong destructive and lethal effect on the external and internal ventilation facilities of the navy ship. In this paper, through the study of the principle of the explosion shock wave, a solution for the explosion shock wave protection before the filtering and ventilation device of the collective protection system of the ship is proposed, and the ventilation valve (HFB series anti-shock wave valve) that can be immediately and quickly closed has been successfully developed, which can effectively prevent the entry of shock waves to ensure that the filtering and ventilation device is not damaged. The product has been verified by a large number of simulated shock wave tests, which satisfies the isolation requirements of the filtering and ventilation device for explosion shock waves, and achieves a breakthrough in the isolation technology of anti-explosion shock waves for domestic ships.
