Abstract
The invention discloses a civil air defence door airtightness detection device which comprises a box body, an air delivering device and an air regulating device, wherein the air delivering device and the air regulating device are communicated with the reverse side of the box body. The obverse side of the box body is provided with a rectangular opening, a door body to be detected is arranged at the rectangular opening, a communicating pipe between the air delivering device and the box body is internally provided with a pressure regulating valve, the air regulating device comprises a pressure transmitter, a pressure signal port of the pressure transmitter is communicated with the box body, and an electric signal end of the pressure transmitter is connected with a controlled end of the pressure regulating valve through a pressure regulator. A lower end of the box body is provided with a mobile track, and the reverse side of the box body is provided with a water tank. An airtight door installed on the box body performs the air delivering step and cooperates with the air regulating device. When a set test pressure is achieved, the quantity of air passing through a gas meter during a period is read out, and a physical formula is used for calculating the air leakage rate of the airtight door in the standard condition. Meanwhile, the door body to be detected and one end of the box body are put into water for convenient observation, and airtightness is convenient to observe.
