Description

Technical Field

[0001] The utility model relates to the technical field of sealed fireproof doors, in particular to a sealed fireproof door sealing performance testing device. Background Art

[0002] Fire doors mainly include: steel, stainless steel fire doors, wooden fire doors, wooden decorative fire doors, molded board fire doors, pipe well fire doors, suitable for civil buildings and industrial buildings. When installing fire doors, in some specific environments, such as laboratories, fire doors need to be installed to prevent radiation, gas and other leakage from polluting the environment. When two relative fire doors are fitted and sealed, it is necessary to test the sealing to determine whether they meet the requirements of manufacturing, installation and operation. At present, the light method and smoke method are mostly used to test the sealing of fire doors. Among them, the light method needs to emit light indoors in a darker environment to pass through the fire. The door gap is used to observe whether light is transmissive. The smoke method is to use a smoke generator to blow smoke indoors and observe whether the smoke disperses. Although the above methods can detect the sealing performance, the light method has certain requirements for the environment. If the surrounding environment is bright, the observation effect will be affected. When the smoke method is emitting smoke, if a small amount of smoke is emitted from the gaps of fire doors and windows, it cannot be observed by the naked eye, resulting in inaccurate sealing detection, and the direction of smoke dispersion cannot be guided, resulting in slow detection progress due to the self-diffusion of smoke. In addition, it is not convenient to collect smoke as much as possible when it diffuses indoors or outdoors, which easily pollutes the environment.

[0003] In the above scheme and the prior art, when conducting a sealing test on a sealed fire door, the sealing test on the sealed fire door is performed by collecting diffused smoke through a detection device for statistical analysis. This testing method will be affected by the sealing performance of the detection device and the result of the sealing test on the sealed fire door cannot meet actual use requirements.
