Abstract
The invention provides a novel long-time delay detonator with a shock-conducting tube. According to the technical scheme, the novel long-time delay detonator comprises the shock-conducting tube, a tube shell, a delay element and a plain detonator, wherein the delay element is arranged in the tube shell, one end of the tube shell is connected to the plain detonator, the other end of the tube shell is connected to the plastic shock-conducting tube, the plain detonator makes contact with the delay element, the end, connected to the shock-conducting tube, of the tube shell is closed up, and a detonation space is reserved between the shock-conducting tube and the delay element. The novel long-time delay detonator can be adjusted according to different length needs of the delay element, a rubber plug for assembling the detonator with the shock-conducting tube is effectively eliminated, the process of middle clamping is eliminated, the production cost is saved, the structure is simplified, and the water repellency and the ignition reliability are improved.
Description
Technical field
What the present invention relates to is a kind of delay detonator, especially a kind of novel long delay Nonel detonator.
Background technology
The research and development of long delay Nonel detonator are civilian initiating equipment field research and development bottleneck and difficult point, also be that the focus of rear research and development eliminated by fuse cord in recent years, several long delay Nonel detonator structures existing in current industry, but still there is the other detonator delay duration of high section (combustion speed) instability, complex structure, high in cost of production defect.Now exist a lot of not enough to current industry technology, mainly be structure and assembly technology complexity, Fire Reliability is poor, water-resistance is poor, the other detonator delay duration of high section (combustion speed) is unstable, delay element complex structure, manufacturing procedure and the problem such as all swivel links are many, this is the weak point existing for prior art.
Summary of the invention
Object of the present invention, be exactly for the deficiency existing for prior art, and a kind of technical scheme of novel long delay Nonel detonator is provided, the program adopts injection-moulded housing to be connected with the direct bayonet socket of detonator, can need along with delay cell length difference and adjust, effectively eliminate the rubber stopper of assembling Nonel detonator simultaneously, eliminate " card waist " operation, save production cost, simplify the structure, improve water proofing property and reliability of igniting.
This programme is achieved by the following technical measures:
A kind of novel long delay Nonel detonator, includes detonator, shell, delay element and basal detonator; Shell inside is provided with delay element; One end of shell is connected with detonator; The shell other end is connected with plastic detonating tube; Detonator contacts with delay element; One end that shell is connected with detonator is closing in shape; Be provided with between detonator and delay element and ignite space.
Preferred as this programme: detonator is provided with segment mark.
Preferred as this programme: shell is injection-moulded component.
Preferred as this programme: shell is connected by clipping machine bayonet socket with detonator.
Preferred as this programme: align with the lower surface of shell in the lower surface of delay element.
Preferred as this programme: the size of shell matches with delay element.
The beneficial effect of this programme can be learnt according to describing of such scheme, be connected owing to adopting the direct bayonet socket of shell and detonator in this scenario, shell is interior without rubber stopper simultaneously, shell can carry out size adjusting according to the requirement of delay element, provide can expand space for increasing delay detonator delay duration further, effectively simplify production process simultaneously, save production cost.
As can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention.
In figure, 1 is detonator, and 2 is shell, and 3 is delay element, and 4 is detonator, and 5 is segment mark.
Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, this programme includes detonator, shell, delay element and basal detonator; Shell inside is provided with delay element; One end of shell is connected with detonator; The shell other end is connected with plastic detonating tube; Detonator contacts with delay element; One end that shell is connected with detonator is closing in shape; Be provided with between detonator and delay element and ignite space; Detonator is provided with segment mark; Shell is injection-moulded component; Shell is connected by clipping machine bayonet socket with detonator; Align with the lower surface of shell in the lower surface of delay element; The size of shell matches with delay element.
The basal detonator that the present invention relates to owing to not needing to consider that the filling of delay element is built-in, therefore can adopt the basal detonator of instantaneous cap structure, and detonator tube length is generally 50-60mm;
The injection-moulded component length that the present invention relates to is determined according to its built-in delay element length in principle, is thought of as and reduces its length specification kind, can different section not, length delay element uses same specification injection-moulded component;
For ensureing Nonel detonator Fire Reliability (i.e. delay element can reliable ignition basal detonator), basal detonator strengthening cap top with mouth end below injection-moulded component in the face of together, need will be close in delay element lower surface time " bayonet socket ";
The delay element that the present invention relates to need be built in injection-moulded component, and delay element external diameter should basically identical with injection-moulded component internal diameter (can built-in but do not loosen);
The present invention relates to injection-moulded component material is low-density high-pressure polyethylene in principle, and also can add various additives according to its melt temperature and changing firmness requirements realizes, and can make injection mold according to its finished article design, injection molten polyethylene.
The detonator that the present invention relates to uses common plastics detonator or highstrenghtpiston's detonator, when using high strength detonating tube, consider the melting connectivity of injection-moulded component and high strength detonating tube cladding material, the material of injection-moulded component is preferably consistent (or can merge effectively mutually) with detonator material.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
