Book text can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
It is as shown in Figs 1-4: a kind of driving device for explosive valve of the utility model, comprising:
Shell 1；
Igniter 2 is located on the shell 1, and 2 bottom of igniter is equipped with taper flash hole 3, and the taper passes fire
3 inner wall of hole is equipped at intervals with multiple vortex deflectors 31, positioned at the bottom of the taper flash hole 3 of each vortex 31 end of deflector
Portion is equipped with the first seal disc 4, and first seal disc 4 is fixed on shell 1；
Gunpowder chamber 5 comprising positioned at the first gunpowder chamber group 51 of 3 bottom of taper flash hole, positioned at the first gunpowder chamber
The second gunpowder chamber 52 on the flame emission direction of group；The first gunpowder chamber group 51 includes the two level-one gunpowder set in parallel
Chamber 511, positioned at each 511 cavity wall of level-one gunpowder be radially equipped with it is multiple set medicine platform 512, it is the multiple to set medicine platform
512 width successively becomes larger from top to bottom；
Seal assembly 6, be located at the first gunpowder chamber group 51 bottom, the seal assembly 6 include upper seal 61,
With the lower seal 62 of 61 clearance fit of upper seal；The upper seal 61 includes upper ring body 611, and the upper ring body is set
There are two concentric ring groove 6111, the boss being welded and fixed with 51 bottom of the first gunpowder chamber group is equipped in the middle part of the upper ring body 611
612, connecting rod 613 is inlaid between the boss 612 and each concentric ring groove 6111 and passes through connecting rod 613 will
It is fixed；
The lower seal 62 includes the protrusion 621 being oppositely arranged with upper ring body 611 and opposite with the boss 612
The recess portion 622 of setting；With the second gunpowder chamber 52 by being welded and fixed, the recess portion 622 is equipped with vertical for the bottom of the recess portion 622
Downward multiple arcs through-hole 6221, the multiple arc-shaped through-hole 6221 are connected to the second gunpowder chamber 52；
Second seal disc 7 is fixed on the bottom of the shell 1.
Working principle: the utility model using 3 points sparking by the way of, first it is multiple set placed on medicine platform 512 it is enough
Gunpowder with to full combustion, meanwhile, a certain amount of gunpowder is pre-installed in igniter 2 as introduction, fire is ignited, flame passes through cone
Shape flash hole 3, and the first seal disc 4 is melted；Flame enters the first gunpowder chamber group 51, and gunpowder is ignited, sets medicine due to each
Platform shape in a ring, for placing gunpowder, multiple tapered runners setting medicine platform and being collectively formed reduce the width of transfer fire runner,
So that flame is formed vortex flow direction in taper flash hole 3, improves the gunpowder pressure that conflagration generates in taper flash hole 3；
The flame being pressurized enters upper seal 61, due to concentric ring groove 6111 height be less than upper ring body 611 other
Partial height when flame passes through, concentric ring groove 6111 is melted, and the other parts of upper ring body 611 are not melt away, simultaneously
The part not being melt away can catch the not sufficiently combusted gunpowder fallen from taper flash hole 3, avoid plug for seal component 6,
It is further sufficiently burned simultaneously；Flame continues to be transmitted to lower seal 62, if there is not sufficiently combusted gunpowder with concentric ring
The fragment of groove 6111 is fallen on down on protrusion 621 together, is further sufficiently burned；Due to upper seal 61 and lower seal 62
Clearance fit, be transmitted to recess portion 622 from concentric ring groove 6111, form Y-shaped runner, that is, reduce the width of transfer fire runner
Degree, improves the pressure of flame；
By pressurized flame by multiple arcs through-hole 6221, the setting of arc avoids flame and the through-hole with prismatic
Friction is generated, the loss of flame energy in transmission process is reduced；Finally, the second seal disc 7 is melted by flame, fast using gunpowder
Quick burning burns the piston motion that the pressure generated pushes explosive valve valve, improves flame in the pressure of transmission process, final realize is opened
Valve.
In another example, each vortex deflector 31 is arc-shaped, and the opening of taper flash hole 3 is arranged in top
Place.In this way, flame is forming vortex flow direction in taper flash hole 3, meanwhile, arc reduces flame in transmission process
In with 3 inner wall of taper flash hole collision, friction, with realize reduce flame energy in transmission process loss.
In another example, 4 materials of first seal disc are copper sheet；The material of second seal disc 7 is steel disc.
The fusing point of the copper sheet is 1083 degree, and the fusing point of steel disc is 1515 degree, since the gunpowder in igniter 2 is low dose of, it is sufficient to
Copper sheet is melted；The intracavitary gunpowder of gunpowder is large dosage, and the gunpowder on the one hand making the second gunpowder intracavitary is sufficiently burned, another party
Steel disc can be melted by face, embody the practicality.
In another example, the edge for setting medicine platform 512 far from each of described 3 side of taper flash hole is equipped with taper baffle
513, the taper baffle is 120 degree~150 degree with the angle for each setting the formation of medicine platform 512.In this way, to realize fire
Medicine will not be slipped off from 512 edge of medicine platform is set, meanwhile, so that gunpowder is come into full contact with flame, full combustion, taper baffle
513 can also be melt away, and flame is avoided to be stopped by taper baffle 513, improve the pressure that the conflagration of flame generates.
In another example, the bottom of the seal assembly 6 is fixed in shell 1 by pillar 8.In this way,
The support of seal assembly 6 is fixed with realizing, making each section, Each performs its own functions, improves the driveability of the device.
In another example, the width of the upper ring body 611 is greater than the width of protrusion 621, and the width of the boss 612 is small
In the width of recess portion 622.In this way, the runner of flame is reduced, to realize the high pressure runner of flame, improves flame
Pressure in transmission process is prepared for the subsequent piston for pushing explosive valve, to realize subsequent valve opening process.
In another example, the igniter 2 is at least one, and matches with the quantity of level-one gunpowder chamber 511.Using
This mode, the quantity of igniter 2 needed for selecting according to the actual situation, has use value.
In another example, the boss 612 is flushed with the top of connecting rod 613.In this way, boss 612 with
Connecting rod 613 is welded and fixed with 51 bottom of the first gunpowder chamber group jointly, the stability of enhancement device.
Number of devices and treatment scale described herein are the explanations for simplifying the utility model.To the utility model
The application of the driving device for explosive valve, modifications and variations will be readily apparent to persons skilled in the art.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
