摘要:
建筑物承受高压容器爆炸荷载作用的泄爆设计被日益重视。本文开展了在容积为0.15 m3方形容器中泄爆实验测试。实验装置一端连接高压管道，模拟产生高压爆炸。另一端连接泄爆装置，对不同压力作用的泄爆装置开启过程进行了实验研究。实验结果给出了不同爆炸压力条件下容器内压力发展时程和泄爆装置开启压力、开启时间等指标，对于高压容器的泄爆防护具有工程应用价值。
The design of vented explosion has attracted more concerns for industrial buildings subject to ex-plosive loading of high pressure vessel. The present paper performs the experimental testing re-search of vented explosion within 0.15 m3 rectangular enclosure. High pressure pipeline, using to simulate the explosive behavior, and explosive venting device are respectively connected to both sides of experimental system. The opening process of venting device is studied within different pressure loadings. The major parameters of initial opening pressure and opening period are in-vestigated with the variations of pressures. The experimental results show the practical values in the design for the protection of explosive venting of high pressure vessel.
