Description
Technical field
The invention belongs to explosive wastewater fields, are related to a kind of explosion self-desttruction equipment, and in particular to a kind of for cylinder test
Explode self-desttruction equipment.
Background technique
Energy release and the test to metallic copper wall acceleration capacity when cylinder test is a kind of expansion of measurement detonation product.Quilt
It surveys explosive to occur to light a fire in the case where initiation system provides initiation energy stimulation and rise to detonation state, while metallic copper wall is done
Function, driving fragmentation movement.During test, external environment variation, especially outside energy stimulation can generate test result dry
It disturbs, influences test accuracy.It is higher that excessively high initiation energy will lead to test result, therefore it is required that initiation energy is slightly above tested
The Critical Initiation threshold value of explosive.Due to the limitation of initiation energy, often there is non-proper detonation or puts out in sample during test
Quick-fried phenomenon.When initiation system does not have proper detonation explosive, needs to check test assembling process, line status etc., endanger
Dangerous height.Existence conditions cannot achieve the long-range destruction to powder charge and initiation system.
Summary of the invention
Cannot achieve to solve existence conditions include to cylinder test powder charge detonator long-range destruction, the purpose of the present invention exists
In providing a kind of explosion self-desttruction equipment for cylinder test, which realizes pair under the abnormal detonative action of cylinder test
The explosion Destruction of cylinder test powder charge.
The metal jet that explosion self-desttruction equipment of the invention generates when being using the detonation of explosive shape charge through metal every
Plate, generates the principle of damage effect, provides energy source for self-desttruction equipment；It is quick-fried by being placed in cylinder test powder charge detonation end point
Fried self-desttruction equipment, in the case where cylinder test priming device does not act on normally, cylinder test powder charge of detonating.The present invention utilizes primacord
The speed of ignition principle smaller than explosive detonation velocity of wave propagation generates time-lag action in the normal detonation of cylinder test, destroys certainly
Destroying device does not have an impact cylinder test result.Since cylinder test powder charge is when putting out quick-fried, the energy meeting of initiation system generation
Physical perturbation is generated to explosion self-desttruction equipment, the use reliability for the self-desttruction equipment that influences to explode, the present invention is by test, using fried
Medicine detonation rate is greater than the principle to the near field driving speed of product and external environment, devise relative to cylinder test detonation from
Ruin delay technique.When delay time is excessive, cylinder test puts out the quick-fried reliability that will affect explosion self-desttruction equipment；It is being delayed
When time is too small, when cylinder test normally acts on, explosion self-desttruction equipment, which can also explode, generates energy, influences cylinder test test
