Pressurization-ignited explosive device

Abstract

The invention relates to a pressurization-ignited explosive device which comprises a high-pressure-resistant vessel, wherein one end of the high-pressure-resistant vessel is provided with at least one rupture disk or pressure relief valve, and the other end is provided with a high-pressure hydraulic liquid or high-pressure compressed gas pressurization end; large and small variable-diameter piston cylinder body cavities are arranged in the high-pressure-resistant vessel; piston bodies having matched dimensions with the corresponding cylinder body cavities are respectively arranged in the two cylinder body cavities; each piston body moves in the corresponding cylinder body cavity; a pressurizable solid-state, liquid-state, gas-state or supercritical fluid substance is filled in the cavity on the side of the first end of the high-pressure-resistant vessel of the large piston; and when external force pushes the small piston to amplify the external force by using different areas of the large and small pistons, the large piston is pushed to pressurize the substance in the cavity on the side of the first end, so that the substance in the cavity on the side of the first end is quickly released and expands, thereby completing the explosion. The invention can solve the technical problems of high-pressure gas explosion and the like, has the advantages of no naked fire, no release of polluting gas or chemical substances, environment friendliness and high safety, and is convenient to use.

Description

technical field

[0001] The invention belongs to the field of explosive devices and relates to an explosive device for boosting and detonating high-pressure gas or / and liquid or supercritical fluid. Background technique

[0002] At present, blasting mainly adopts 1. All kinds of explosions are caused by gunpowder and fuel. The explosion simultaneously produces open flame, high temperature and high pressure gas. In many working applications, open flame will cause the danger of fire hazard. High temperature will cause damage to many materials. At the same time, the explosion pressure is cannot be accurately controlled. 2. There are also heating plastics or inflatable containers to heat and expand the contents of the container until the container ruptures and release high-pressure gas. However, it is difficult for an inflatable container to withstand high pressure, and the position of releasing gas cannot be controlled. When installing an inflatable container, open it. The size...
