In actual life, develop rapidly along with modern industry, oil, mining industry, urban construction all needs a large amount of steel pipe building materials, the processing of steel pipe has been proposed to high processing request, particularly in order to improve the corrosion resistance of steel pipe, to steel pipe inner wall, to spray and pay corrosion-inhibiting coating, for improving the tack of corrosion-inhibiting coating and steel pipe, before steel pipe sprayed coating coating, to eliminate rust to its inner surface, the bead degreasing, therefore, the spray gun of shot-peening directive steel pipe inner wall is the key technology that steel pipe internal-surface is processed, the spray gun that has occurred various versions in prior art, wherein (application number 200820055010.5) spray gun for steel tube inner-wall reinforced peening of Shanghai Xinyaxin Technology Co., Ltd.'s research and development is applied well, this spray gun has a nozzle and a spray boom, its nozzle sets is contained in spray boom front end, this nozzle has an outer tube and a Water conservancy diversion core, wherein the front end of Water conservancy diversion core has a large head end, this spray gun forms an annular slot for the ejection of ball gas mixed flow between nozzle Water conservancy diversion core and outer tube front opening.But there is defect, its Water conservancy diversion core is that the fin by being provided with in outer tube is connected with outer tube, and in shot-peening process, this fin affects ball gas fast moving, has affected the speed of sand ball, thereby has affected the shot-peening quality of steel pipe inner wall.
Utility model content
Problem to be solved in the utility model is to provide ball blast spray gun in a kind of steel pipe, and the sand ball being sprayed by this spray gun can be injected into steel pipe internal-surface fast.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: ball blast spray gun in a kind of steel pipe, comprise that pipeline and plug are stifled, this pipeline comprises the sand inlet being communicated with successively, flow-guiding channel and sand export, described sand inlet is the trumpet type of outward opening, described plug gets lodged in sand export place and is connected with pipeline, the tapered end face of the stifled end face inwardly of described plug for protruding, the link of sand export and flow-guiding channel and this tapered end face form ring cavity, described pipeline tilts at tube wall corresponding to ring cavity is provided with a plurality of through holes, and the angle that the angle that the center line of described through hole forms with the center line of flow-guiding channel and the bus of tapered end face and the center line of flow-guiding channel form is identical.
Further, described sand export is being trumpet type with flow-guiding channel link, and this horn-type opening outwardly.
Further, the angle that the center line of described through hole and the center line of flow-guiding channel form is 45 °.
Further, described plug is stifled is threaded with sand export.
Further, the stifled one end outwardly of described plug is provided with tightens element, described in tighten element side rolled decorative pattern.
Further, described pipeline is radially provided with 2～3 grooves at the outer surface of sand inlet.
Further, described plug blocks up the carbon tool steel into T10.
Advantage and the good effect that the utlity model has are:
1). the utility model sand inlet is opening horn mouth outwardly, is then connected with flow-guiding channel, and this design can increase the speed of the sand ball flowing through, thereby has further improved the quality of shot-peening.
2). the incline direction of the utility model through hole is identical with the conical surface of tapered end face, and this design has guaranteed the circulate of sand ball.
3). because spray gun is loss-type instrument, plug of the present utility model is stifled to be threaded connection with pipeline, and it is stifled that this design can be changed plug in time, and then reduced cost, improved efficiency.
4). the sand ball speed being sprayed by spray gun is high, the hardness of sand ball own is larger, larger to filling in the damage of stifled tapered end face, therefore need periodic replacement plug stifled, the utility model is provided with tightening piece in the stifled one end outwardly of plug, and the side of this tightening piece rolled decorative pattern, like this easy operating, change the stifled simple and fast of plug, improved efficiency.
5). because the sand inlet of shot-blasting machine is connected (not shown in FIG.) with delivery hose, pipeline of the present utility model is provided with groove at the outer surface of sand inlet, this design can increase the frictional force of flexible pipe and pipeline, and then makes the connection of flexible pipe and pipeline more firm.
6). the stifled T10 carbon tool steel plug of selecting of plug in the utility model is stifled, when guaranteeing the stifled toughness of plug, has also guaranteed to fill in stifled hardness, relative prolongation fill in stifled service life, reduced and changed the stifled frequency of plug.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model front view;
Fig. 3 is pipeline cutaway view of the present utility model;
In figure: 1, sand inlet, 2. groove, 3. flow-guiding channel, 4. pipeline, 5. ring cavity, 6. through hole, 7. sand export, 8. tightens element, 9. decorative pattern, 10. plug is stifled.
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Fig. 1, shown in Fig. 2 and Fig. 3, ball blast spray gun in a kind of steel pipe, comprise pipeline 4 and plug stifled 10, this pipeline 4 comprises the sand inlet 1 being communicated with successively, flow-guiding channel 3 and sand export 7, described sand inlet 1 is the trumpet type of outward opening, the sand ball being sprayed into by horn mouth like this enters after flow-guiding channel 3, space diminishes, and then ejection, this design can further improve the speed of sand ball, and then further improved the shot-peening quality of steel pipe internal-surface, described plug stifled 10 is connected with pipeline 4 at sand export 7 places, the tapered end face of described plug stifled 10 end face inwardly for protruding, sand export 7 forms ring cavity 5 with link and this tapered end face of flow-guiding channel 3, described pipeline 4 tilts at the tube wall of ring cavity 5 correspondences is provided with a plurality of through holes 6, and the angle that the angle that the center line of described through hole 6 forms with the center line of flow-guiding channel 3 and the bus of tapered end face and the center line of flow-guiding channel 3 form is identical, it is unobstructed that this design has guaranteed to enter the operation of shot-peening of pipeline 4, and can by through hole 6, be ejected smoothly.Described sand export 7 is being trumpet type with flow-guiding channel 3 links, and this horn-type opening outwardly.Ring cavity 5 now consists of inwall and the trumpet type joint face of tapered end face, sand export 7, and this design can further guarantee that the circulation of sand ball in pipeline 4 is smooth and easy.The angle that the center line of the through hole 6 in the utility model and the center line of flow-guiding channel 3 form is 45 °.Described plug stifled 10 and sand export 7 are threaded, plug stifled 10 can be conveniently changed in this design, reduce cost and further improved efficiency, in this plug stifled 10 one end outwardly, be provided with and tighten element 8 in addition, decorative pattern 9 has been rolled in described side of tightening element 8, by the decorative pattern 9 rolling, be easy to operate filling in stifled 10, time saving and energy saving.Outer surface at sand inlet 1 in the design is radially provided with 2～3 grooves 2, and sand inlet 1 is connected with delivery hose, and the design of groove 2 can increase the frictional force of flexible pipe and pipeline 4, and then makes the connection of flexible pipe and pipeline 4 more firm.Described plug blocks up the carbon tool steel into T10, and this design has guaranteed the hardness of tapered end face.
