Abstract
The utility model relates to a mortar jet-flow spray head for clearing gun barrel coppering. The mortar jet-flow spray head comprises a spray head body, wherein a mortar steady flow layer is arranged in the spray head body, jet-flow channels communicated with a spray head inner cavity are formed in the spray head body, fixed screw caps are arranged in the jet-flow channels, and nozzles are embedded into the fixed screw caps. By utilizing the mortar jet-flow spray head, the proper pressure can reach 5 MPa, the highest withstand pressure can reach 10 MPa, the rifle coppering can be effectively cleared, and the firing accuracy of a gun can be effectively recovered; and the working efficiency is high, and a 100-caliber howitzer can be thoroughly cleared within two hours. The mortar jet-flow spray head has the advantages of long service life, better cleaning effect and wide application range.
Description
Technical field
The utility model relates to a kind of gun barrel coppering and removes the mortar fluid jet nozzle.
Background technology
During the shell emission, super-pressure emission thrust due to projectile tail, the body guidance tape passes through at a high speed Pipe rifling, the two-way interaction, the guidance tape that the rifling that hardness is high is lower to hardness (copper) produces the cutting effect, thereby makes missile rotation, under HTHP, working angles makes guidance tape that complicated physics, chemical change occur, and quite a few residues in barrel with complicated chemical component, forms " coppering ".Therefore, after the ball firing of the certain radix of experience, need to repair to recover fire accuracy to the artillery bore cleaning.
The cleaning way in the past generally adopted is Chemical cleaning, with cleaning fluid and the special hairbrush of faintly acid formula, gun barrel barrel inwall is rubbed with the hands to brush repeatedly.During cleaning, manually hold brush, dip cleaning fluid, insert barrel, then do not stop reciprocating sliding, rotation stirring, operation labor intensity is higher, time-consuming length, the howitzer of 100 bores need to could clean and put in place the time about a week, and Chemical cleaning also easily causes environmental pollution and goes to bits.
Multiple cannon cleaning bore of cannon machine also once appearred in prior art, but there is complex structure mostly in the shower nozzle of these cannon cleaning bore of cannon machines, can't drop into the defect that row cleans, inefficiency to the blind hole in bore and gap isogonism, and easily infringement, service life is shorter.
The utility model content
The technical problems to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and a kind of high efficiency is provided, and the gun barrel coppering of long service life is removed the mortar fluid jet nozzle.
The technical scheme that its technical problem that solves the utility model adopts is:
The gun barrel coppering is removed the mortar fluid jet nozzle, comprises head body, and head body inside is provided with mortar current stabilization layer, on head body, has the jet spray road communicated with nozzle cavity, and the jet spray is provided with fixedly blind nut in road, fixedly on blind nut, is embedded with nozzle.
Further, described nozzle is the ruby nozzle.
Further, described jet spray road inwall is provided with tapered tread, fixedly the blind nut periphery also is provided with tapered tread, jet spray road and fixedly blind nut by screw thread, spin, fixedly blind nut one end is provided with M shape locking slot, at M shape locking slot with fixedly under the effect of blind nut periphery tapered tread, the ruby nozzle can firmly be clamped, and has fundamentally avoided coming off and damaging of nozzle.Fixedly the blind nut other end is provided with and has N shape groove.
Further, described head body is provided with an even numbers jet spray road, every two jets spray road is a pair of, the jet angle of sprinkler flow that forms two a pair of jet spray roads is identical, jet angle of sprinkler flow refers to the angle of jet spray road and shower nozzle axis, spray swing angle also identical, spray swing angle and refer to the angle of jet from tangentially throwing away mortar current stabilization layer.The steady fluid layer boundary of jet spray road center line and mortar circle is tangent.
Use the utility model, applicable pressure can reach 5MPa, and the highest withstand voltage 10MPa that reaches can clear up the rifling coppering effectively, recovers the artillery shooting precision, high efficiency, and the howitzer of 100 bores can clean out within 2 hours.The utility model long service life, cleaning performance is better, applied widely.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1,2, the present embodiment comprises head body 1, and head body 1 inside is provided with mortar current stabilization layer 2(referring to Fig. 5), on head body 1, have the jet spray road communicated with nozzle cavity, the jet spray is provided with fixedly blind nut 3 in road, fixedly on blind nut 3, is embedded with nozzle 4.
Described nozzle 4 is the ruby nozzle.
Described jet spray road inwall is provided with tapered tread, fixedly blind nut 3 peripheries also are provided with tapered tread, jet spray road and fixedly blind nut 3 by screw thread, spin, fixedly blind nut 3 one ends are provided with M shape locking slot 5, at M shape locking slot 5 with fixedly under the effect of blind nut 3 periphery tapered treads, the ruby nozzle can firmly be clamped, and has fundamentally avoided coming off and damaging of nozzle.Fixedly blind nut 3 other ends are provided with and have N shape groove 6(referring to Fig. 6).
With reference to Fig. 3,4,5, described head body 1 is provided with an even numbers jet spray road, every two jets spray road is a pair of, the jet angle of sprinkler flow that forms two a pair of jet spray roads is identical, jet angle of sprinkler flow refers to the angle of jet spray road and shower nozzle axis, spray swing angle also identical, spray swing angle and refer to the angle of jet from tangentially throwing away mortar current stabilization layer.
When shower nozzle advances from left to right in gun barrel barrel 7, it is right that jet A and jet B form an injection, jet A dextrorotation ejection, the contrary churning of jet B go out, spraying swing angle is D2(0 °<D2≤90 °), jet angle of sprinkler flow is D1(0 °<D1≤90 °), the jet emission direction is opposite with the shower nozzle direction of advance, and it is D3 that jet namely sprays spacing to the distance along axis direction.The steady fluid layer boundary of jet spray road center line and mortar circle is tangent, boundary circular diameter D4.
The nozzle structure that is applicable to 100 bore gun barrel barrels is as follows: comprise 2 jet groups, each jet group has 10 injections right, always has 40 jet spray roads.On shower nozzle 1, be processed with 40 conical inner screw threads be used to fixedly blind nut 3 is installed.
When structure shown in the utility model was used for to the gun barrel barrel of 100～122mm bore, optimal clean pressure can reach 3.5 ~ 4.2MPa; Best angle: D1=60 degree, D2=28 degree.
