Insulation and explosion-proof system for aircraft fuel tank and installation technology and application thereof

Abstract

The invention discloses an insulation and explosion-proof system for an aircraft fuel tank and the installation technology and application thereof; the insulation and explosion-proof system comprises a box body and insulation and explosion-proof material units arranged in the box body; the oil outlet on the bottom of the box body is provided with a steel mesh sheet so as to prevent foreign matters from flowing into the combustion system through a pipeline; the insulation and explosion-proof system is good in filling uniformity and compaction, uses less materials, thus saving engineering construction time, and reducing construction cost and discharge and disassemble difficulty; more importantly, the insulation and explosion-proof system can effectively save oil gas losses, can reduce pollutions on the atmosphere environment, and can better improve the box body safety.

Description

technical field [0001] The invention relates to the technical field of installation of barrier explosion-proof materials, in particular to a barrier explosion-proof system for aircraft fuel tanks and its installation process and application. Background technique [0002] At present, in the field of barrier explosion-proof, the barrier explosion-proof material is processed from metal foil into a metal mesh and then filled into the storage tank. The filling method used in the prior art is to make the barrier explosion-proof material into a roll and stack it directly in the storage tank. Or put the barrier and explosion-proof materials into some prepared frame units first, and then stack them into the storage tank. [0003] However, in the actual installation process of the above two installation methods, on the one hand, due to gravity extrusion, the uniformity of the explosion-proof material in the storage tank is likely to be poor, and structural deformation will occur, ther...

Problems solved by technology

[0003] However, the above two installation methods, in the actual installation process, on the one hand, due to gravity extrusion, the uniformity of the explosion-proof material in the storage tank is likely to be poor, and structural deformation will occur, thereby affecting the explosion-proof effect or affecting the storage tank. Normal use; on the other hand, when the fuel tank of the aircraft is emptied, the air-inflated self-drainage method suitable for small and medium-sized tanks is no longer feasible. Because the fuel tank has a large volume, the gas inflated accumulates, and the internal pressure is easy to generate, and the external air can no longer be used. Filling in, resulting in incomplete clearing of the warehouse, which in turn affects the explosion-proof effect of the fuel tank
