Separator for preventing sabot from following

Abstract

The invention discloses a separator for preventing a sabot from following, which comprises a pill, the sabot and a separating chamber of the pill and the sabot, wherein one end of the separating chamber is connected with the outlet end of a transmitting tube, and the separating chamber is provided with a leakage opening; a separating block is arranged in a cavity body of the separating chamber, the separating block is provided with a penetrating central hole, one end of the separating block is conical, the other end of the separating block is cylindrical, and the cylindrical end of the separating block contacts a top screw and is fixed at the port part of the separating chamber through the top screw; and a conical installing position faces to the transmitting tube and is positioned above the leakage opening, and the central hole of the top screw is communicated with the central hole of the separating chamber. The separator has a simple structure and can reliably prevent the separated sabot from advancing along with the pill and entering a recovery room, and the recovery purity of the pill is ensured.

Description

technical field [0001] The invention belongs to the technical field of pyrotechnics laboratory test devices, and relates to a separator, in particular to a separator used in a propellant and explosive test sample launching device to follow the bulletproof bracket into a recovery room. Background technique [0002] When studying the performance of explosives, the danger of explosives is a problem that people are very concerned about and pay attention to. The fragility test is one test used for hazard assessment of explosives. The principle of the test is to launch a projectile with a certain mass at a certain speed through the launching device, so that the projectile hits the steel target plate, and the residual debris after the impact of the projectile is collected into the recovery room, and the loss of the recovered residual debris is less than a given value. By performing an ignition test on the recovered residual fragments in a closed high-pressure container, the p-t cu...

AI Technical Summary

Problems solved by technology

[0003] (1) Auxiliary gas filling equipment is required, and the structure is complex;

[0004] (2) Due to the different purposes of the experiment, it is not necessary to consider the recovery purity of the projectile after impact, that is, the trace and whereabouts of the bullet rest are not considered after separation
