Abstract

The invention relates to an airtightness detection system of a civil air defense door. The system comprises sealing cabin, a control system installed in the sealing cabin and a to-be-detected civil air defense door arranged in the sealing cabin. The control system comprises a pressure increasing mechanism, a pressure reducing mechanism, a smog spraying mechanism, a leakage measurement device and a vacuumizing mechanism. The pressure increasing mechanism, the pressure reducing mechanism, the smog spraying mechanism, the leakage measurement device and the vacuumizing mechanism are installed in the sealing cabin. A human-machine interface is arranged on the side end of the sealing cabin. The control system is connected with the human-machine interface. The smog spraying mechanism is a high pressure smog sprayer and sprays colored smog body. The interior of the sealing cabin is a dust-free environment. A civil air defense door installation rack is installed in the sealing cabin. According to the invention, airtightness of the civil air defense door can be effectively and simply measured; positions of air holes can be positioned; convenience is brought for repair; and the detection device is simple, low in cost and suitable for promotion and use.

Description

technical field [0001] The invention relates to an air tightness detection system for a civil air defense door, which belongs to the technical field of industrial fire safety. Background technique [0002] Civil defense is also called civil defense. Civil defense is an international common term. It is an activity in which the government mobilizes and organizes the masses, adopts anti-airstrike, disaster relief measures, implements rescue operations, and prevents and mitigates disasters. The civil air defense door belongs to the civil defense protection equipment. As the name suggests, the civil air defense door is the door of the entrance and exit of the civil protection project. [0003] Civil defense doors include protective doors, airtight doors, subway partition doors, explosion-proof rubber hose valves, hanging plate valves, protective airtight screen doors, airtight screen doors, airtight (shield) observation windows, protective fire airtight doors, fire airtight doors...
