Description
Technical Field
The invention belongs to the field of civil air defense engineering quality detection, and particularly relates to an air pipe connecting device for detecting air tightness of a civil air defense closed channel.
Background
The air tightness of the civil air defense channel is directly related to the function of isolating toxic gas in the civil air defense space, the air tightness detection is needed, although two ventilating pipes for detection are reserved in the wall body of the civil air defense closed channel, one ventilating pipe is used for inflating, the other ventilating pipe is used for measuring pressure, the inner side of each ventilating pipe is connected with a plug through internal threads, the pipe thread is located on the inner side of the civil air defense channel and is difficult to be connected with an air pipe of detection equipment, the air pipe of the detection equipment is sealed with the ventilating pipe by generally adopting a method of filling sealant, the sealing reliability is difficult to guarantee, the canning and the disassembly of the sealant are time-consuming.
Disclosure of Invention
The invention provides an air pipe connecting device which is used for solving the problem that a reserved air pipe is difficult to connect with an air pipe of detection equipment in the process of a civil air defense channel tightness test.
The invention discloses an air pipe connecting device for air tightness detection of a civil air defense closed passage, which comprises a pipe joint A, a pipe joint B and a quick-plugging joint, wherein one end of the pipe joint A is hermetically connected to an internal thread reserved in a wall body of the civil air defense closed passage, the other end of the pipe joint A is provided with a cavity for accommodating the quick-plugging joint, the quick-plugging joint is used for plugging an air pipe of detection equipment, the quick-plugging joint is arranged in the internal thread of the pipe joint B, the pipe joint A is hermetically connected with the pipe joint B, and the quick-plugging joint is positioned in the cavity of the pipe joint A after the pipe joint A.
When the device is used, the pipe joint A and the pipe joint B of the connecting device are disassembled, the plug on the vent pipe is reserved in the anti-sealing channel is disassembled, the pipe joint A is connected to the internal thread of the vent pipe in a sealing mode, the inflation pipe of the detection device is inserted into the vent pipe from the outer side of the civil air defense channel and then is inserted into the quick insertion joint, the pipe joint B is connected to the pipe joint A in a sealing mode, the other set of device is installed on the other vent pipe in the same mode, the pressure measuring pipe of the detection device is inserted into the quick insertion joint, the sealing door in the sealing channel is closed, and the air tightness detection can be carried out on the civil air defense sealing channel by opening the detection device.
The invention relates to an air pipe connecting device for air tightness detection of a civil air defense closed passage, which comprises a pipe joint A, a pipe joint B and a quick-plugging joint, wherein one end of the pipe joint A is hermetically connected to an internal thread reserved in a wall body of the civil air defense closed passage, the other end of the pipe joint A is provided with a cavity for accommodating the quick-plugging joint, the quick-plugging joint is used for plugging an air pipe of detection equipment, the quick-plugging joint is arranged in the internal thread of the pipe joint B, the pipe joint A is hermetically connected with the pipe joint B, and the quick-plugging joint is positioned in the cavity of the pipe joint A after the pipe joint A is hermetically connected with the pipe joint B.
