Anti-corrosion structure for metal pipeline in wet environment

Abstract

This utility model relates to an anti-corrosion structure for metal pipelines in humid environments, applied in the field of pipeline corrosion protection. It includes an installation pipe with a receiving box fixedly connected to its outer surface. A worm gear is rotatably connected to the inner bottom wall of the receiving box, with the upper end of the worm gear rotatably penetrating the receiving box. A worm wheel is rotatably connected to the inner cavity of the installation pipe, with the worm gear and worm wheel meshing. A positioning tube is provided in the inner cavity of the worm wheel, with its front and rear ends fixedly connected to the front and rear inner walls of the installation pipe, respectively. The worm gear drives the worm wheel to rotate, causing the adjusting rod in the adjusting groove to move longitudinally, driving the pressure strip to press the sealing ring towards the center of the installation pipe, thereby compressing and sealing pipelines of different diameters. Two frustum-shaped sealing tubes can fit against both sides of the outer surface of the pipeline, providing a double seal and effectively reducing corrosion at pipeline joints. It is also applicable to pipelines of various sizes, thus effectively improving the applicability of the anti-corrosion structure.
