Description
Technical field
The present invention relates to ammunition safe practice field, be specifically related to a kind of body exhaust delayed release device.
Background technology
Weapons and ammunitions are in production, transport, storage and use procedure, while being subject to the abnormal thermal stimulation effect such as hot environment or fire, may cause the igniting blast of explosive, even develop into the major accidents such as chain explosion, cause great economic loss and social negative effect.
For increasing the thermal safety of ammunition, conventional method comprises the low sense explosive of development, brushing heat-barrier material and increase heat insulation structural etc.Existing method respectively has shortcoming, such as, the development of low sense explosive need to be considered the matching problem between explosive energy, reliable initiation and sensitivity; The method of brushing heat-barrier material is subject to the restriction of material development level, and the effect of heat insulation of most heat-barrier materials in the time being subject to the roasting combustion of big fire is limited, and not yet finds heat insulation material completely at present; Increase heat insulation structural and can slow down the temperature-rise period of ammunition, but also cannot fundamentally solve the problem of ammunition decomposes, burning.
In the process of explosive decomposes, burning, can discharge a large amount of gas and heat, and the sealing condition of explosive is closely related in the severe degree of ammunition reaction and body, if can in time discharge the gas that in body, explosive generates, the security that can effectively improve ammunition.
Summary of the invention
The present invention has overcome the development of for example low sense explosive of prior art need to consider the matching problem between explosive energy, reliable initiation and sensitivity, provide a kind of and can in time discharge the gas that in body, explosive generates, can effectively improve the body exhaust delayed release device of ammunition security.
The present invention is by the following technical solutions:
A kind of body exhaust delayed release device, it is made up of gland, base, connector and low melting material assembly, offer exhaust passage at described base middle part, described low melting material assembly is in discharge duct, above described base, be provided with gland, between described low melting material assembly and gland and described base, be connected by connector, and described base by thread is connected with body.
In the technical program by offer exhaust passage at base middle part, and in exhaust passage, be provided with low melting material assembly, thereby weapons and ammunitions are in storage, in transportation, in the time that ammunition is subject to the abnormal thermostimulation such as baked wheaten cake and hot environment, explosive in body can discharge a large amount of gas and heat, low melting point assembly is melting gradually under temperature and pressure coupling, so just can make the conducting of low melting material assembly, thereby normally worked in exhaust passage, with the gas that in discharge body, explosive decomposition generates, reach and reduce to press in body, thereby improve the object of weapons and ammunitions security.
Further technical scheme is, described low melting material assembly is polyethylene, engineering plastics, nylon or Merlon.
Surface temperature while reaction according to explosive in the technical program (for example, 130 DEG C～230 DEG C), low melting material is chosen as to polyethylene, engineering plastics, nylon or Merlon, thereby having reached explosive in body arrives before LFL lower flammable limit or demolition point, the timely melting of low melting material, normally worked in exhaust passage, the gas in time explosive being produced is discharged, and reduces the pressure in body.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can become exhaust passage by Fast terrain, presses thereby reduce in body, reaches the object that reduces explosive reaction severe degree.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of body exhaust delayed release device of the present invention.
As shown in Figure 1, wherein the Reference numeral name of correspondence is called:
1 gland, 2 bases, 3 low melting material assemblies, 4 connectors, 5 exhaust passages.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated.
A kind of body exhaust delayed release device as shown in Figure 1, it is by gland 1, base 2, connector 4 and low melting material assembly 3 form, it is characterized in that offering exhaust passage 5 at described base 2 middle parts, described low melting material assembly 3 is in discharge duct 5, above described base 2, be provided with gland 1, and be connected by connector 4 between described low melting material assembly 3 and described gland 1 and described base 2, and described base 2 is connected with body by fine thread, described low melting material assembly 3 is polyethylene, engineering plastics, nylon or Merlon, the thickness of low melting material assembly 3 is 3mm.
In the process of storage, transport weapons and ammunitions, in the time that weapons and ammunitions are subject to the abnormal thermostimulation such as baked wheaten cake and hot environment, under the gas that explosive discharges in body and the effect of heat, low melting material assembly 3 first gradually melting forms passage, and before explosive reaches LFL lower flammable limit or demolition point, normally worked in exhaust passage 5, reach the effect of exhaust step-down, can reduce the severe degree of ammunition reaction in body.
According to one embodiment of present invention, to select thickness be the polyethylene of 3mm to low melting material assembly 3.Under 130 DEG C of temperature and air pressure 3.8MPa coupling, make low melting material assembly 3 form steam vent, diameter is about 2.5mm～3.5mm, along with the rising of temperature, described low melting material, gradually in molten condition, can make exhaust passage 5 normally work under less gas pressure.
" embodiment ", " another embodiment ", " embodiment " that spoken of in this manual, etc., refer to specific features, structure or the feature described in conjunction with this embodiment and be included at least one embodiment that the application's generality describes.In description, multiple local appearance statement of the same race not necessarily refers to same embodiment.Furthermore, while describing a specific features, structure or feature in conjunction with arbitrary embodiment, what advocate is to realize this feature, structure or feature in conjunction with other embodiment also to fall within the scope of the invention.
Although invention is described with reference to multiple explanatory embodiment of the present invention here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiments, within these amendments and embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the building block of subject combination layout and/or layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
