Problems solved by technology

[0008] However, the above-mentioned aircraft inerting system has the following problems, that is, the aircraft inerting system enters the working state after the aircraft leaves the ground to ensure the safety of the fuel system, and its ground cooling fan 2 is only enabled when the aircraft inerting system is maintained on the ground , so after the aircraft leaves the ground, the ground cooling fan 2 is turned off
But, under this mode of operation, above-mentioned ground cooling fan 2, cooling one-way valve 3 and its relevant bypass conduit all will become unnecessary weight when aircraft flies, thereby increased fuel consumption and have had a strong impact on the economy of aircraft thus benefit

Abstract

The invention describes a conduit connection device, comprising: a ground joint, which is airtightly connected with air source equipment; a connecting pipe, one end of which is airtightly connected with the ground joint; an adjusting bracket, which includes a support attached to the outer surface of the connecting pipe a seat part and at least two foot parts extending from the seat part; a suction cup attached at the ends of the at least two foot parts of the adjustment bracket for adsorption on a surface; and a flexible tube, one end of which is connected with the connecting tube The other end is airtightly connected, and the other end completely covers the opening of the surface to which the suction cup is sucked. The present invention no longer needs a ground cooling fan, a cooling check valve and its associated bypass duct, thereby removing excess weight and improving the economic benefit of the aircraft; Therefore, the existing ground air source equipment can be directly connected; in addition, the present invention is convenient to use, simple to operate, and quick to disassemble and disassemble, thereby greatly improving the work efficiency.

Description

technical field [0001] The invention relates to the field of connection devices, in particular to a surface adsorption type conduit connection device, and more particularly to a surface adsorption type conduit connection device for an aircraft inerting system and a cold edge air source conduit during ground maintenance. Background technique [0002] In the field of aviation, the explosion-proof problem of fuel tanks has always been the focus of aircraft airworthiness and safety. In the past two decades, fuel tank deflagration accidents caused by excessive fuel vapor in the fuel tank have occurred one after another around the world. To this end, the FAA has clearly put forward airworthiness requirements and system installation standards for this field through Article 25-981 and SFAR 88, and requires the installation of fuel tank inerting systems on aircraft. The fuel tank inerting system uses the air separation component to control the volumetric oxygen concentration in the ...
