Abstract

The utility model provides a novel fuse type ignition detonator, which belongs to the technical field of the civil blasting accessories, in particular to a delay type ignition detonator. Ignition composition is filled at the lower part of a igniter plug, the interior of which is spliced with a detonating tube, and the detonating tube is communicated with the ignition composition filled at the lower part of the igniter plug; a vacant position of 5 to 8 mm is arranged between the igniter plug and a delay fuse, one or two exhaust holes with the diameter being 2 mm are opened on a detonator shell which corresponds with the position that the vacant position is 1 to 2 mm away from the delay fuse, and the exterior(s) of the exhaust hole(s) is(are) sealed with a tackiness paper tape. The utility model reduces the cost of the detonator, being above 90 percent compared with the core tube delay type ignition detonator, and being above 80 percent compared with the lead delay type ignition detonator; at the same time, the utility model has the advantages that no misfire exists, the change in delay time is stable, the production process is simplified, and the quality of the detonator is improved.

Description

Novel fuse cord formula Nonel detonator

Technical field

The utility model belongs to civilian initiating equipment technical field, is specifically related to a kind of extension formula Nonel detonator, international Patent classificating number: F42B 3/00.

Background technology

A high second amount extension Nonel detonator part of domestic production at present is tubular type extension method in taking, another part is to adopt plumbous extension body formula extension method, and interior pipe extension body formula and plumbous extension body formula Nonel detonator have complex manufacturing, shortcoming that cost is high.After delay powder in particularly this two kinds of detonators is stored a period of time, because its oxidation reaction has reduced the activity of self, combustibility obviously degenerates, and flame sensitivity obviously descends, detonator is produced miss-fire, it is obvious more that measure high more this phenomenon of detonator second.Someone once attempted replacing interior extension body and the plumbous extension body of managing with fuse cord, to solve height second amount Nonel detonator shortcoming, measured easy misfire and second a unsettled phenomenon but fuse cord formula extension Nonel detonator exists.

Summary of the invention

Goal of the invention of the present utility model provides the novel fuse cord formula Nonel detonator that a kind of cost is low, storage period long, amount was stablized, was difficult for miss-firing second.

Goal of the invention of the present utility model is achieved through the following technical solutions: the bottom at capsule is filled with hexogen, top at hexogen is filled with priming, on the top of priming the extension fuse cord is installed, corresponding capsule place is pressed with the card seal at extension fuse cord middle part; Top at capsule is equipped with igniter plug, is filled with ignition charge in the bottom of igniter plug, is inserted with detonator in the inside of igniter plug, and this detonator communicates with the ignition charge of igniter plug bottom filling; Be pressed with the card seal at the corresponding capsule oral area of igniter plug place; The room that the 5-8 millimeter is arranged between igniter plug and extension fuse cord has 1-2 diameter and is 2 millimeters steam vent, at the outside of steam vent adhesive tape sealing of hole apart from the capsule place of the position correspondence of extension fuse cord upper surface 1-2 millimeter in this room.

The shell of detonator can be (as Fig. 1) such as box hat, copper shell, paper shell, plastic housings.The extension body adopts fuse cord formula extension body, and this extension body can satisfy amount requirement second of GB 94171-2003 " Nonel detonator ", and the igniter plug cock body adopts rubber stopper, and detonator can be that common detonator also can be the high strength detonator, but that explosion velocity is difficult for is too high.Ignition charge in the igniter plug can be that the gas ignition charge is arranged also can be the non-pneumatic ignition charge.

The utility model has reduced the cost of detonator, compare with the Nonel detonator of interior pipe extension formula and to reduce cost more than 90%, compare with lead extension body formula Nonel detonator and to reduce cost more than 80%, thoroughly having solved simultaneously fuse cord formula extension Nonel detonator miss-fires and second unstable problem of amount, simplify the production technology of present high second amount extension Nonel detonator, improved the quality of high second amount Nonel detonator.

Fig. 2 is the structural representation of the utility model igniter plug;

Fig. 3 is the structural representation of the utility model capsule.

The specific embodiment

Shown in Fig. 1-4, be filled with

hexogen

1 and 2 in the bottom of capsule 6, be filled with priming 3 on the top of hexogen 2, on the top of priming 3 extension fuse cord 4 is installed, be pressed with card seal 12 at the corresponding capsule in extension fuse cord 4 middle parts 6 places; On the top of capsule 6 igniter plug 5 is installed, is filled with ignition charge 9 in the bottom of igniter plug 5, be inserted with detonator 7 in the inside of igniter plug 5, this detonator 7 communicates with the ignition charge 9 of the bottom filling of igniter plug 5; Be pressed with card seal 8 at igniter plug 5 corresponding capsule oral area places; The room that the 5-8 millimeter is arranged between igniter plug 5 and extension fuse cord 4, have 1-2 diameter in this room apart from capsule 6 places of the position correspondence of extension fuse cord 4 upper surface 1-2 millimeters and be 2 millimeters steam vent 10, in the outside of steam vent 10 with adhesive tape sealing of hole 11.

Making step of the present utility model is: it is 2 millimeters steam vent 10 that two diameters are made a call at the middle part of the first step on capsule 6, with relatively thinner adhesive tape 11 steam vent 11 is pasted firm (see figure 1) again; Second step was made blasting cap, and the gradation dress is pressed RDX, DDNP in capsule 5; Extension fuse cord and card seal 12 that the 3rd step, dress was pressed in blasting cap are fixing; The 4th step sealed, and detonator 7 is inserted in the igniter plugs 5, and the igniter plug that will have detonator again inserts to tighten behind the body and gets final product.

The pressing density of hexogen 1 should be greater than the pressing density of hexogen 2.
