建设能容纳50人的试验用避难硐室,将不同类型、不同规格的泄压阀分别装设于避难硐室生存室的上部和下部,测得泄压阀的开启压力、排气量以及排气管末端风速。通过对所测试验数据的分析,总结得出适合避难硐室用泄压阀的设计方案、硐室内最佳布置位置以及泄压阀安装时应关注的重点问题,为井下避难硐室及人防过程关于泄压阀选型、安装和验收提供科学适用的理论基础和数据支撑。

Construction can accommodate up to 50 people refuge chamber for the trial, the different types and sizes of relief valve were installed in the upper and lower refuge chamber survival chamber, measured the relief valve opening pressure, displacement and row Tracheal end wind speed. Through the analysis of the tested data, we concluded the design scheme of relief valve for refuge chamber, the optimal layout of the chamber and the key issues that should be paid attention to when installing the relief valve, as well as the underground chamber and civil air defense process On the relief valve selection, installation and acceptance to provide a scientific and applicable theoretical basis and data support.
