Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
As shown in fig. 1, the utility model provides a people's air defense door gas tightness detection device, including door frame 1, people's air defense door 2 is installed on door frame 1, steel sheet 3 seal weld is passed through at the back of door frame 1, forms the pressure chamber between people's air defense door 2, door frame 1 and steel sheet 3, set up the air inlet on the steel sheet 3, this air inlet seal installation intake pipe 4, the outside air supply of intake pipe 4 connection, install overflow valve 5 and micromanometer 9 on the steel sheet 3.
Preferably, the air inlet position of nearly steel sheet 3 on the intake pipe 4 installs micro flow meter 6, air supply pressure gauge 7 is installed to the inlet end of intake pipe 4, looks over the rate of admitting air through micro flow meter 6 to detect air supply pressure through air supply pressure gauge 7.
In the embodiment, when the civil air defense door 2 is closed, high-pressure gas is quickly flushed into a pressure chamber formed by the civil air defense door 2, the door frame 1 and the steel plate 3 through the gas source, so that the internal gas pressure reaches the test pressure, the gas in the chamber is stabilized at the standard pressure value through the pressure relief valve 5 on the steel plate 3, after the standard pressure value is stabilized, the change of the micro-flow meter 6 is observed to determine whether the gas leakage amount is qualified, if the gas leakage amount is unqualified, bubble water is sprayed on the periphery of the sealing surface of the civil air defense door 2 and the door frame 1 to observe whether bubbles emerge to determine the gas leakage position, after the gas leakage position is determined, the position is marked, the civil air defense door 2 is opened, the structure of the standard position is adjusted to meet the standard requirement, and the gas tightness is detected again until the gas tightness is qualified.
Specifically, the civil air defense door 2 is rotatably mounted on the door frame 1 through a hinge 8.
To sum up, the utility model discloses people's air defense door gas tightness detection device is used for people's air defense door leaf to adjust and detect people's air defense door gas tightness performance before dispatching from the factory, and the purpose of adjustment is to find out gas leakage position, and adjust the relevant technical requirement in this position, and the purpose of detection is in order to detect the gas leakage of people's air defense door unit time and compare with the standard value, judges whether qualified; the detection device has the advantages of simple structure, reliable detection, low detection cost and convenient operation.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
