Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] Such as Figure 1-2 As shown, the portable protective airtight door airtight performance detection device includes an air source, a pressure measuring device, a portable console 7, a sealed support plate 4, a sealed pipe 3, a civil air defense door 1, and civil air defense door frames 2 on both sides of the civil air defense door 1. Portable The console 7 controls the air source to inject gas into the sealed tube 3 through the intake pipe 5 connected to the sealed tube 3, and the sealed tube 3 expands to both sides, and is tightly pressed against the civil air defense door frame 2 and the sealed support plate 4 to form an overpressure chamber. During the detection, the overpressure chamber and the portable console 7 are connected into a system and installed by using the air inlet pipe and the pressure measuring pipe, so as to realize the airtight performance detectio...

Abstract

The invention relates to a portable protective airtight door air-tightness detection device which includes a gas source, pressure measuring equipment, a portable console, and a portable hyper-pressure chamber. The portable hyper-pressure chamber includes a sealing plate and sealing pipes at the two ends of the sealing plate. When the gas source supplies gas to the sealing pipes under control of the portable console, the sealing pipes expand and push against the sealing plate and a frame of a detected airtight door. A hyper-pressure chamber is formed by the sealing plate, the detected airtight door and the frame of the detected airtight door. The pressure measuring equipment tests the pressure change when gas is injected into the hyper-pressure chamber at a certain speed. With the device adopted, the detection efficiency of air-tightness of protective airtight doors (including airtight doors) in workshops is improved greatly, and the problem that it is impossible to detect the air-tightness of a single-frame protective airtight door on a project site at present in our country is solved. The detection device can be widely used in independent and rapid detection of air-tightness of protective equipment.

Description

technical field [0001] The invention relates to a sealing performance testing device, in particular to a device capable of testing the sealing performance of a single protective airtight door at an installation site, and belongs to the technical field of protection engineering testing. Background technique [0002] At present, the relevant documents of the National Civil Defense Office on the production, installation, and quality inspection of protective equipment require that the protective equipment have a quality inspection report before acceptance. However, the commonly used airtight performance testing methods for protective equipment include flow method and differential pressure method. At present, the above methods can only be realized in laboratories or protective equipment production workshops. The demand cannot be met. [0003] In addition, the airtight performance test system of protective equipment commonly used at present is usually composed of inflatable equip...
