Background

Under some special circumstances, it is necessary to cut containers or pipelines containing flammable and explosive gases or liquids such as natural gas and liquefied petroleum gas, but it is necessary not to cause the contents to burn or explode synchronously. The materials such as natural gas, liquefied petroleum gas and the like stored in the container or the pipeline have the characteristics of flammability and explosiveness, and when the materials form a mixture with oxygen in the outside air and reach a certain concentration, the materials can be combusted or exploded when meeting the conditions of high-temperature open fire and the like and reaching the ignition condition.

The energy-accumulating cutting cable is a rope-shaped special blasting equipment which is characterized by that it uses a proper metal material as shell body, adopts V-shaped charge, utilizes the principle of producing energy-accumulating effect by explosion and can produce high-pressure energy-accumulating jet flow to penetrate through target during explosion.

The action principle is that after the energy-gathered cutting rope is detonated by a detonator, the explosive is exploded to quickly crush the shaped charge liner to collide at the axis and focus to form continuous jet flow which moves at high speed along the normal direction of the energy-gathered liner, and the continuous jet flow is commonly called as a jet flow knife. When the jet flow head meets the target plate, the speed is high and is about 3900-4500 m/s, the collision between the jet flow head and the target plate can be approximate to fluid collision, jet flow penetrates into the target plate to form cutting, and the cutting of the target plate can be realized by utilizing the principle.

However, for the requirement of instantly and rapidly releasing combustible gas, the existing energy-gathering cutting rope is adopted for directly cutting, and after being detonated by a detonator, high-temperature and high-pressure detonation products can be generated, so that the combustible gas and liquid in the detonator can be synchronously ignited, and the special requirement cannot be met. In order to achieve rapid cutting of containers or pipelines in which flammable explosive gases or liquids are stored, and simultaneously, to prevent the containers or pipelines from being synchronously ignited by detonation products, an explosive cutting device meeting requirements is needed.
