SAFE DEVICE FOR ELECTRIC INITIATION OF LIQUID EXPLOSIVES Russian patent published in 2012 - IPC F42D1/45 F42C11/00 

FIELD: explosives.

SUBSTANCE: invention relates to safe devices designed for electric initiation of liquid explosives, both individual and multi-component, such as anticlastic ones. A device comprises a hollow body providing for liquid explosives access inside a body, a resistive element connected to two electrodes in the form of conductors in insulation. One of electrodes is fixed in the body by means of its flattening at one end and when submerged into a liquid explosive is arranged at the bottom, the second electrode is arranged freely, at the same time comprises a unit, arranged inside the body, preventing approach of a resistive element to the inner surface of the body, at least at one side, to the distance below the thickness of the critical layer of liquid explosive detonation. As a unit on a conductor in insulation it is possible to install a bushing or a ball from a non-electroconductive material. And a resistive element may be a section of a conductor from a refractory metal.

EFFECT: invention makes it possible to increase reliability of device actuation and to simplify its design.
