Description

Technical Field

[0001] The utility model relates to the technical field of pipeline anti-corrosion, in particular to a spraying device for anti-corrosion agent of water supply pipelines. Background Art

[0002] As the main artery of urban operation, the water supply pipeline is an important basic facility for the normal life of urban residents. In order to make better use of space, the water supply pipeline is usually buried underground. Therefore, before embedding, it is necessary to carry out anti-corrosion spraying treatment on the water supply pipeline to extend the service life of the pipeline.

[0003] At present, when the existing spraying device for anti-corrosion agent of water supply pipelines was designed at the beginning, it was shaped according to a single specification of water supply pipeline, and the position of the spray head could not be adjusted adaptively. It could only be used for the spraying of anti-corrosion agent on the outer surface of such a specification of water supply pipeline. When it was necessary to process water supply pipelines of other specifications, the distance between the outer wall of the water supply pipeline and the spray head was likely to exceed the appropriate range, affecting the spraying coverage quality of the anti-corrosion agent on the outer wall of the water supply pipeline, and there were limitations in use. Summary of the Utility Model

It could only be used for the spraying of anti-corrosion agent on the outer surface of such a specification of water supply pipeline, and there were limitations in use.
