Abstract

The invention discloses a civil defense equipment airtightness detection platform, comprising civil defense equipment, a pressure measurer, a flow meter and a pull bar; the civil defense equipment is connected with a platform through bolts to form a closed hyper-pressure chamber, ball valve I is connected to one side of the closed hyper-pressure chamber, ball valve II, ball valve III and ball valve IV are mounted sequentially on the other side of the closed hyper-pressure chamber, the flow meter is serially connected between the ball valve I and the closed hyper-pressure chamber, an end of the ball valve I is connected with an air compressor on the platform, an end of the ball valve II is connected with a barometer, an end of the ball valve III is connected with a thermometer, an end of the ball valve IV is connected with the pressure measurer, the pressure measurer comprises a micro-differential pressure transmitter and a computer, the computer is connected with the micro-differential pressure transmitter, and the pull bar is connected at one end with the civil defense equipment and connected at the other end with the platform.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment, in particular to an air tightness detection platform for civil air defense equipment. Background technique [0002] The civil air defense equipment is composed of two parts: the door frame and the door leaf, and the door leaf part also includes the lock and hinge parts. It is a transformation from opening to opening. It is mainly used in various orifices of civil air defense projects. Its main function is to intercept various destructive factors such as shock waves, biological warfare agents, chemical warfare agents, electromagnetic pulses, shrapnel, and early nuclear radiation during wartime. Therefore, the maximum allowable air leakage is an important assessment index for the performance of civil air defense equipment. However, due to the large number of manufacturers and the variety and complexity of equipment types, there are relatively few detection methods and detection...
