TECHNICAL FIELD
[0001] The utility model relates to the technical field of air-tightness test of civil air defense anti-explosion wave floor drain, in particular to a kind of air-tightness test detection device for civil air defense anti-explosion wave floor drain. BACKGROUND
[0002] Civil air defense anti-explosion wave floor drain is usually installed in the civil air defense area of building, and its main function is to dissipate explosion shock wave through ventilation hole, relieve pressure difference and protect personnel and house safety. It is a special floor drain for defending explosion threat. In order to avoid using products with poor sealing performance in engineering, such floor drains need to be tested for air-tightness before leaving the factory. However, the air-tightness test detection device for civil air defense anti-explosion wave floor drain still has some problems in actual use.
[0003] For example, the air-tightness test detection device for civil air defense anti-explosion wave floor drain disclosed in application No. 202120249064.0 includes a mirror image of a sealed lower disc and a sealed upper disc. A connecting piece is arranged between the sealed lower disc and the sealed upper disc to change the distance between the sealed lower disc and the sealed upper disc. A ventilation hole is formed at the top end of the sealed upper disc, and the ventilation hole is connected to one of the connecting ends of a three-way pipe joint. The other two connecting ends of the three-way pipe joint are respectively connected to a pressure gauge and a pressure sensor. The connecting end of the three-way pipe joint connected to the ventilation hole is also connected to an inflation pipe. The inflation pipe is sequentially provided with an inflation check valve, a manual ball valve and an electromagnetic valve. The electromagnetic valve is adjacent to the three-way pipe joint. The electromagnetic valve and the pressure sensor are connected to a control terminal. This solves the problem of large space occupation and immobility of the existing air-tightness detection device for anti-explosion wave floor drain. However, it still has the problem of only being able to realize single high air pressure value test function, which is not easy to test air-tightness under high impact force. This leads to the air-tightness test of the device for civil air defense anti-explosion wave floor drain not being comprehensive enough. Moreover, it is not easy to realize quick positioning and replacement of the civil air defense anti-explosion wave floor drain product to be tested, which leads to poor convenience of the device and difficulty in popularization.
