Embodiment 1

[0029] figure 1 Among them, 1 is a cylindrical shell, made of aluminum, with a smooth surface, no cracks and blisters, and its molding dimensions are: outer diameter 6.1mm, inner diameter 6.0mm, height 70mm. A flameproof body 2 is installed in the middle of the shell, and the shell of the flameproof body 2 is made of iron, with an outer diameter of 5.9mm, an inner diameter of 5.8mm, and a height of 25mm; 3 (3:1) mixed components with a density of 0.8g / cm 3 , The filling height is 23mm. Booster 3 is sealed with wax paper 4, leaving a gap of 2mm above 4, and 5 is the bayonet treatment between the flameproof body and the shell to fix the position of the flameproof body in the shell.

[0030] When used in the field, 6 and 7 ( figure 2 ) is the detonating cord connected to both sides of the flameproof body, 8 and 9 are the interference fit positions between the detonating cord and the shell, so that the detonating cord and the shell are tightly connected. When detonating, 6 pl...

Embodiment 2

[0032] image 3 Among them, 1 is a cylindrical shell, made of iron, with a smooth surface, no cracks and blisters, and its molding dimensions are: outer diameter 12.1mm, inner diameter 12.0mm, height 60mm. A flameproof body 2 is installed in the middle of the shell. The shell of the shell is made of aluminum, with an outer diameter of 11.9mm and an inner diameter of 11.8mm. The booster 3 is made of 0.8g PETN and KClO 4(3:1) mixed components with a density of 0.8g / cm 3 , The filling height is 9mm. The booster is sealed by wax paper 4, and there is a gap of 3mm above the wax paper, and seals 10 and 11 are loaded into both sides of the flameproof body. The seal is 24mm long, with an outer diameter of 11.9mm and an inner diameter of 4.0mm. It is made of rubber. It cannot be pulled out, so as to realize the purpose of quick connection between the detonating cord and the one-way explosion door. The outer diameter of the sealing member is interference fit with the shell, and the ...

Abstract

The invention discloses a unidirectional explosion propagation door element and a method for realizing reliable unidirectional explosion propagation of an explosion network through the unidirectional explosion propagation door element. The unidirectional explosion propagation door element is characterized in that an explosion suppression body in the unidirectional explosion propagation door element can play a role in smooth forward explosion propagation and reverse explosion suppression, and therefore the effect of irreversible detonation is achieved. By means of the unidirectional explosion propagation door element and the method, unidirectional explosion propagation of a detonating cord or a detonating pipe network can be realized, explosion propagation in the explosion network can only be conducted in the designed direction, so that the explosion propagation of the network is unidirectional, namely irreversible, in this way, unsafety, caused by reversible explosion propagation, of the detonating cord or the detonating pipe network can be avoided fundamentally, the safety problem of this type in engineering blasting is solved, and the unidirectional explosion propagation door element and the method have great engineering application prospects.

Description

technical field [0001] The invention belongs to the technical field of detonating materials and blasting, and in particular relates to a one-way blast transmission door element and a method for realizing one-way reliable explosion transmission of an explosion network by using the element. Background technique [0002] The vast majority of blasting projects are realized through the joint action of group charges. The detonation of the group charges is realized through the detonation combination of a single charge, and the detonation combination of a single charge is the detonation network of the group charge. According to different detonation methods, the detonation network is divided into electric detonation network and non-electric detonation network. The electric detonation network is a network composed of electric detonators and wires. The non-electric detonation network is a network composed of detonator detonators, detonating cords, detonators and other components that ...
