Embodiment Construction
[0024] Below in conjunction with the accompanying drawings, specific embodiments of the present invention are given to further illustrate the present invention.
[0025]A kind of anti-corrosion straight spray gun for internal spraying of small-diameter pipelines, including a gun body composed of a gun barrel 9 in the middle, a material connection plate 13 connected to both ends, and a bracket 3. One end of the gun body 1 is a spraying area, and the other end is respectively It is connected to the external feeding device and air supply device through the feed pipeline and air inlet channel set inside it. The inside of the gun barrel 9 also has a pneumatic actuator linked with the external air supply device. Through the external air supply device Drive the internal pneumatic actuator to control the action of the spray area of the gun body; the gun barrel 9 includes a hollow cavity 9-1 axially penetrating through the barrel, two material through cavities 9-3 and two air passage ...

The invention relates to a spray gun, belonging to the technical field of spraying equipment structures, in particular relating to an anticorrosive direct spray gun for the internal spraying of a small-bore pipeline. The anticorrosive direct spray gun is characterized by comprising a gun body, wherein the gun body is composed of a gun tube arranged at the middle of the spray gun, material connection discs connected at the two ends of the spray gun, and a bracket; one end of the gun body is provided with a spray area, and the other end of the gun body is respectively connected with an external material supply device and an external air supply device; the interior of the gun tube is provided with a pneumatic executing component; and the external air supply device drives the pneumatic executing component to execute the operation of controlling the spray area of the gun body. By using the spray gun disclosed by the invention, the problem that the handheld spray gun in the prior art cannot carry out internal spraying operation is solved; because a forward direct spraying operation mode is adopted, the spray gun is more suitable for the spraying of small-bore pipelines, so that the range of spray diameter of the small-bore pipeline reaches Phi 60mm-phi 219 mm; and the problem of pressure on a switch of the spray gun can be completely solved by using four boosting cylinders which are connected in series in the gun tube, the influence on the spray gun arising from process deviation can be completely solved by using adjusting screws arranged at a rear cover in the gun tube, meanwhile, by using the adjusting screws, the adjustment on hollow spraying angles of a nozzle also can be realized.
Description
technical field [0001] The invention relates to a spray gun, in particular to an internal spray anti-corrosion straight spray gun suitable for small-diameter pipelines, and belongs to the technical field of spray coating equipment structures. Background technique [0002] At present, hand-held spray guns are used for spraying polyurea anti-corrosion pipelines. However, the minimum spraying diameter of the existing hand-held spray guns can only reach φ219mm, and pipelines with a diameter smaller than φ219mm cannot be completed due to the limitation of the spray gun structure. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide a small-caliber internal anti-corrosion straight spray gun that can be used for spraying pipes with a diameter in the range of φ60mm-φ219mm. The spray gun is designed for small-diameter pipelines and has a reasonable structure design. , Fast and convenient t...
