Description
Technical Field
The invention belongs to the technical field of initiating explosive devices, and particularly relates to a biaxial flame input one-way output detonator for a fuse.
Background
The primer is an important component of initiating explosive devices. With the improvement of fuse performance, the improvement of functions and the improvement of reliability requirements, the demand for the variety and the number of explosion elements is increasing. However, from the viewpoint of explosion-proof safety design, the smaller the number of explosive elements in the fuze, the better the fuze. It is therefore desirable that the fuze blasting element be able to address the need for multiple excitation fires.
The double-axial flame input and single-direction output detonator is a detonator which changes the traditional single-axial input and output detonator into a double-axial input and single-axial output detonator. Compared with the traditional single-axial input detonator, the double-axial flame input one-way output detonator has a two-side axial flame excitation input mode, improves the input excitation adaptability of the detonator, and greatly reduces the possibility of fuzzing in extreme cases. CN2673862 discloses a bidirectional flame detonator, in which ignition holes are provided at both ends of a detonator shell, and each end of the detonator can be used as a flame input end, thereby having no directional requirement. Although the detonator has bidirectional firing capability, the main application requirements of a high explosive charging explosive element for detonating the detonator are difficult to meet because high explosive charging does not exist.
On the whole, the detonator practical at the present stage is almost a single axial ignition structure, is not favorable for improving the reliability of the fuse action, and is also not favorable for realizing the functions of fire insulation and self-destruction of the fuse.

Compared with the prior art, the invention has the remarkable advantages that:
(1) the detonator adopts a mode of double-axial flame excitation input and single-axial output, replaces the single flame excitation input direction of the original detonator, can solve the problem of multipath excitation ignition by using less explosive elements in a smaller space, improves the reliability of the fuse action on the premise of ensuring the explosion-proof safety, and realizes the functions of fire insulation and self destruction.
