Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0037] Such as figure 1 , 2 As shown, a civil air defense overpressure exhaust valve detection equipment includes a plenum box 1 and a fan 2 connected to the plenum box 1. The plenum box 1 is provided with a mounting hole 3. When in use, the exhaust gas to be tested will be The valve 24 is installed at the installation hole 3, and then air is blown into the plenum 1 by the fan 2 so that the pressure in the plenum 1 changes, and now the exhaust valve 24 can be tested.
[0038] Such as figure 2 , 3As shown, in this embodiment, the plenum box 1 is a rectangular hollow box, and the plenum box 1 is provided with a maintenance sealing door 23 . Wherein, the installation hole 3 is arranged on a side wall of the plenum box 1, and an elastic sealing ring 20 is arranged on the side wall of the plenum box 1 around the installation hole 3. The sealing ring 20 is hol...

The invention relates to a civil air defense overpressure exhaust valve detecting device. The device comprises a static pressure box and a fan communicated with the static pressure box, a mounting hole is formed in the static pressure box, a recessed portion recessing inward is arranged on the static pressure box below the mounting hole, an access hole is formed in the surface, near the mounting hole, of the recessed portion, the static pressure box is internally provided with a clamping member for clamping an exhaust valve and a driving member for driving the clamping member to move from therecessed portion to the mounting hole, the static pressure box is provided with a gate for sealing the access hole, and the static pressure box is internally provided with a pressing device for pressing the exhaust valve at the mounting hole on the mounting hole. In the whole process, only the exhaust valve needs to be placed at the recessed portion, many people are not required to assist the work, and the whole process is automatically operated during installation, so the the installation is convenient and simple.
Description
technical field [0001] The invention relates to the technical field of industrial detection devices, in particular to a detection device for a civil air defense overpressure exhaust valve. Background technique [0002] National defense facilities are an indispensable infrastructure for a country. Various fortifications to deal with wars, especially air defense basements, are widely used and practical as refuges for civilians and soldiers. The overpressure exhaust valve is an important part of various wartime ventilation equipment, and its performance and quality determine the reliability and safety of the entire system. [0003] The patent application publication number CN104132804A discloses an explosion-proof overpressure exhaust valve ventilation dynamic characteristic detection platform, including pressure sensors, static pressure boxes, ball valves, fan brackets, frequency conversion fans and exhaust valves, and frequency conversion fans are installed on the fan bracket...
