Ultra-fast closing device for implosion compression pipeline

The invention discloses an ultra-fast closing device for an implosion compression pipeline. The ultra-fast closing device comprises a priming apparatus, an instantaneous detonator, a plurality of mild detonating fuses, driving explosive, a buffer layer and a metal pipeline, wherein the driving explosive consists of a plurality of explosive sheets which are wrapped on the outer wall of the metal pipeline by a circle at least; one end of each mild detonating fuse is connected with the driving explosive, the other end of each mild detonating fuse is connected with the instantaneous detonator, and the instantaneous detonator is connected with the priming apparatus; and the buffer layer is arranged between the driving explosive and the pipeline, and the density of the driving explosive is larger than 1g/cm . By the aid of the ultra-fast closing device, the pipeline with the inner diameter ranging from 6mm to 20mm can be closed with a good effect in an ultra-fast manner within 100 microseconds. Besides, the ultra-f
