Abstract
The utility model discloses a special piston of an air cannon. The special piston comprises a metal piston sleeve and a convex piston body, wherein the piston body comprises a bulge located at the upper side of the piston body and a bottom block located at the lower side of the piston body, the bulge and the bottom block are in an integral structure, and the metal piston sleeve and the piston body are coaxially arranged; the metal piston sleeve is sleeved on the outer race of the bulge and is located at the upper side of the bottom block, and the outer diameter of the metal piston sleeve is not less than that of the bottom block. The special piston of the air cannon is capable of preventing the jamming of a cartridge.
Description
Technical field
The utility model relates to a kind of air bubble special piston.
Background technique
Air bubble is the strong air flow of the pressurized gas that sprays suddenly, to surpass one
machthe speed of (velocity of sound) directly pours the inaccessible faulty section of storing bulk material, the expansion shock wave of this sudden outburst, overcome material static friction, make the material in container recover again to flow. it is to utilize aerodynamic force principle, can produce powerful impact force, be a kind of desirable block clearing slag-blowing equipmemt of clean, pollution-free, low power consuming.Piston is as the vitals of air bubble, and the structure of himself and material directly have influence on the block clearing effect of air bubble, and existing air bubble piston is mostly nylon piston or rubber piston, and in use, thermal expansion can occur piston, causes piston to get stuck.
Model utility content
The purpose of this utility model is to provide a kind of air bubble special piston of getting stuck of preventing.
For achieving the above object, the utility model adopts following technological scheme: air bubble special piston, the piston body that comprises metallic piston cover and convex, piston body comprises the projection that is positioned at upside and the sole piece that is positioned at downside, projection and sole piece are integral type structure, metallic piston cover and piston body are coaxial setting, and metallic piston cover is sheathed on protruding outer ring and is positioned at the upside of sole piece, and the external diameter of metallic piston cover is greater than or equal to the external diameter of sole piece.
Surface, described metallic piston Tao outer ring is provided with the first metal annular groove, closure gasket groove and the second metal annular groove from top to bottom successively.
The end face of described metallic piston cover flushes with protruding end face.
The end face of described projection is provided with toroidal cavity.
The material of described metallic piston cover is abrasion resistant cast steel or stainless steel or aluminum alloy.
The material of described piston body is macromolecule nylon.
Air bubble special piston described in the utility model, because metallic piston cover is metal material, has wear-resistingly, and the on-deformable advantage of being heated, so be difficult in use getting stuck.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
By the air bubble special piston shown in Fig. 1 and Fig. 2, comprise the metallic piston cover 3 of annulus column and the piston body of convex, piston body comprises the projection 2 that is positioned at upside and the sole piece 7 that is positioned at downside, and projection 2 and sole piece 7 are cylindrical shape and projection 2 and sole piece 7 for integral type structure.Metallic piston cover 3 is sheathed on the outer ring of projection 2 and is positioned at the upside of sole piece 7, and metallic piston cover 3 and piston body are coaxial setting, and metallic piston cover 3, projection 2 and sole piece 7 threes are coaxial line setting.Metallic piston cover 3 is fastenedly connected by drive fit with projection 2.The end face of described metallic piston cover 3 flushes with the end face of projection 2, and protruding 2 end face is provided with toroidal cavity 1, and toroidal cavity 1 is for mounting spring in use.The external diameter of metallic piston cover 3 equals the external diameter of sole piece 7.
The surface, outer ring of described metallic piston cover 3 is provided with the first metal annular groove 4, closure gasket groove 5 and the second metal annular groove 6 from top to bottom successively.The first metal annular groove 4, closure gasket groove 5 and the second metal annular groove 6 are the circular groove that overlaps 3 surfaces, outer ring around metallic piston.During use, described the first metal annular groove 4 and the second metal annular groove 6 are interior, and all for helical pitch ring is installed, helical pitch ring is metal ring, and helical pitch ring and the sliding contact of air bubble inwall, play the effect of guide-localization; Closure gasket groove 5 in the middle of being positioned at is for installing seal ring.The material of piston body is macromolecule nylon, and the material of metallic piston cover 3 is abrasion resistant cast steel.
Certainly, the present invention is not limited to above-mentioned form, and the external diameter of metallic piston cover 3 also can be slightly larger than the external diameter of sole piece 7, and the material of metallic piston cover 3 also can be stainless steel or aluminum alloy, all can reach goal of the invention.
Because metallic piston cover 3 is metal material, have wear-resistingly, the on-deformable advantage of being heated, so air bubble special piston of the present invention is difficult for getting stuck in use.
