Abstract
A kind of exploder mechanism bleeder screw is the utility model is related to, is a kind of bleeder screw for being used in military products closed bomb tests equipment play compression and degassing.The utility model includes bolt body, air vent is provided with bolt body, the aperture of air vent one end is located at the head of bolt body located at the aperture of the tail end side of bolt body, the other end, the tail end of bolt body is provided with arc groove in end, bolt body includes bolt A sections and bolt B section, and bolt A sections and bolt B section are connected through a screw thread in the rod body of bolt body.After the utility model, bolt A sections can be recycled for a long time, and only with bolt B section is changed, bolt B section is easy to process, therefore testing expenses substantially reduce.
Description
Technical field
A kind of exploder mechanism bleeder screw is the utility model is related to, is that one kind is used in military products closed bomb tests equipment rise
The bleeder screw of compression and degassing.
Background technology
Closed bomb vessel belongs to one of conventional test device of explosive wastewater industry, and bleeder screw belongs to important in the device
One of part.It is as follows using process：First the explosive wastewater that test is measured with regulation is put into closed bomb vessel, is put into experiment afterwards
With steel ball, finally steel ball is fixed with bleeder screw end arc groove, using the screw thread carried on bleeder screw body by steel
Pearl is firmly fixed and withstands explosive wastewater.After installation, Field Force withdraws, and is struck sparks using electricity and ignites explosive wastewater, laboratory technician
Record data.Gas can be produced after being exploded because of explosive wastewater, makes to produce certain pressure in exploder mechanism, after the completion of data record, gas
Excluded from the air vent inside bleeder screw, make to be in atmospheric pressure state in exploder mechanism.After exhaust, operating personnel take outburst apart
Device, bleeder screw, steel ball etc. are taken out, and cleaned, carry out closed explosion test next time.
During experiment, test steel ball and bleeder screw belongs to consumable accessory.Experiment steel ball directly contacts with explosive wastewater,
Ignition point, steel ball is directly by the impulsive force of explosive wastewater, and in use, steel ball is easily deformed, damaged.In test,
Continue to do experiment using the steel ball of deformation, the accuracy of data can be influenceed, therefore steel ball needs to change in time.Bleeder screw end
Groove plays fixation test steel ball, during experiment, by explosive wastewater spacing impulsive force, groove can be caused to deepen,
Phenomena such as change is big, and groove steel column position is thicker, cracking.Groove deepens, become it is big cause can not fixation test steel ball well, it is recessed
Channel column position cracking causes the insufficient strength for compressing experiment steel ball, and sealing difference is easily " deflation ", and these phenomenons all can
Make test data inaccurate.Therefore bleeder screw is also required to regularly replace.
At present, domestic closed bomb vessel is integral type with bleeder screw, and after a certain number of uses, bottom can deform nothing
Method uses, therefore replacement frequency is higher.Bleeder screw is special material is made, processing technology is more complicated, price.Frequently change
Experimentation cost is caused to increase.
Utility model content
The utility model aims to solve the problem that the problem of closed bomb vessel bleeder screw is frequently changed, causes experimentation cost high, carries
Made simply, securely and reliably for one kind, the exploder mechanism bleeder screw for wasting, reusing can be avoided.
Technical scheme is used by solve above-mentioned technical problem the utility model：Exploder mechanism bleeder screw, including spiral shell
Bolt body, is provided with air vent in bolt body, and the aperture of air vent one end is located at the tail end side of bolt body, the other end
Aperture is located at the head of bolt body, and the tail end of bolt body is provided with arc groove in end, and bolt body includes bolt A
Section and bolt B section, bolt A sections and bolt B section are connected through a screw thread in the rod body of bolt body.
It is further：Air vent is L-shaped, and one section positioned at bolt body head is set along the axis of bolt body
Put, another section perpendicular to bolt body axis set.
It is further：Bolt B section is one section with arc groove, and the right angle portion of air vent is in bolt B section.
The beneficial effects of the utility model are：Bleeder screw is changed to by integral type split type.Part I is main part
The bolt A sections divided, it is responsible for playing promotion, fastening bleeder screw using the screw thread of bolt body itself, compressing experiment steel ball
Effect.Part II is the bolt B section with gunpowder contact portion, and this portion end surface has arc groove, is responsible for the examination that is fixed and clamped
Test steel ball, and the internal right angle portion for having air vent.Bolt A sections, using being threadedly coupled, make the deflation of bolt B section with bolt B section
Hole is connected with the air vent in bolt A sections, has the function that exhaust, pressure release.
Closed bomb vessel bleeder screw material is special, structure is complex, therefore processing charges is higher.In long-term exploder mechanism
Bleeder screw is often changed during experiment, causes experimentation cost to remain high.Using the utility model, bleeder screw is designed as
It is removable, because bolt A sections do not contact with explosive wastewater and impact part experiment steel ball, therefore there will not be the generation of damage phenomenon, can
It is recycled for a long time.Bolt B section and impact part experiment steel ball directly contact, using can be deformed surely after a period of time, it is necessary to more
Change, after new bolt B section and bolt A sections reconnect or an intact exploder mechanism bleeder screw.Bolt B section small volume,
Simple in construction, easy processing, it is cheap.Therefore closed bomb tests are carried out using bleeder screw of the present utility model, can be big
It is big to reduce testing expenses.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Parts, position and numbering in figure：1- air vents, 2- arc grooves, 3- bolt A sections, 4- bolt B sections.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes bolt body, air vent 1, the one end of air vent 1 are provided with bolt body
Aperture the head of bolt body is located at located at the aperture of the tail end side of bolt body, the other end, the tail end of bolt body exists
End is provided with arc groove 2, and bolt body includes bolt A sections 3 and bolt B section 4, and bolt A sections 3 and bolt B section 4 are in bolt
The rod body of body is connected through a screw thread.
Make it that structure is more reliable, air vent 1 is L-shaped, positioned at one section of bolt body head along in bolt body
Axis set, another section perpendicular to bolt body axis set.Bolt B section 4 is one section with arc groove 2, is deflated
The right angle portion in hole 1 is in bolt B section 4.
