Problems solved by technology
Restricted by the conditions stipulated in the standard method, the direct detection of single protective airtight doors (including airtight doors) can only be carried out in laboratories or protective equipment production workshops in China at present, and cannot be realized on the engineering site, resulting in the current domestic protective equipment. After installation, the airtight performance test cannot be implemented, leaving a huge hidden danger to the overall protection performance of the project

The invention belongs to the technical field of protective engineering detection, and particularly relates to a method and a device for detecting the airtightness of a protective airtight door. The method for detecting the airtightness of the protective air-tight door comprises the following four steps: 1, constructing a detection device, and constructing a closed cavity by using a door frame and a door body of the protective air-tight door; 2, detecting the air tightness of the detection device; 3, inflating the closed cavity to a preset overpressure value; 4, detecting the air leakage of the door leaf. The airtight performance detection device for the protective airtight door comprises an air source, a flow meter, a barometer, a first film, a second film and an opening and closing piece. The air tightness of the detection device can be confirmed during detection, and the measurement result is accurate. The scheme can also solve the problem that sealing performance detection after engineering field installation cannot be directly measured, and has the characteristics of safety, reliability, material saving, environmental protection and high efficiency.
Description
technical field [0001] The invention belongs to the technical field of protection engineering detection, in particular, the invention relates to a detection method and a detection device for the airtight performance of a protection airtight door. Background technique [0002] Protective equipment is installed at the entrance and exit of protective engineering personnel, equipment, weapon perforation and air intake, and smoke exhaust pipe (pit) crossings. It is used to block shock waves, biochemical agents or weaken shock waves. Airtight performance is its key quality control item. Protective airtight doors (including airtight doors) are an important protective equipment, and there has been no direct measurement method for the airtight performance test after installation on the engineering site. [0003] In addition, there are two commonly used airtight performance testing methods for protective equipment: the flow method and the differential pressure method. Restricted by t...
