Refuge Room Closed Door (BMB800*1500-BMB1000*1800 Series) Product Introduction
The main function of the refuge chamber is to provide life support for people in distress who cannot be evacuated in time when a disaster accident occurs underground. For this reason, the airtight door of the evacuation chamber is designed with two doors that open outward. For ease of observation and safety reasons, both doors are equipped with observation windows. The first outer door adopts a protective airtight door that can resist the impact pressure of not less than 1.0MPa and can block toxic and harmful gases, and the second inner door adopts a closed door that can resist the impact pressure of not less than 0.3MPa and can block toxic and harmful gases, and it should be ensured that the air pressure inside the refuge chamber is always higher than the external ambient air pressure of more than 100Pa during the whole rated protection time. At the same time, in order to resist the high temperature flue gas, the interlayer of the two doors is filled with thermal insulation materials with good thermal insulation performance.
