Description

Technical Field

[0001] The utility model relates to the field of pipeline connection, in particular to a corrosion-resistant and leak-proof metal compensator. Background Art

[0002] Pipeline is a kind of transportation tool, which can transport gas, solid and liquid substances. However, the length of the pipeline is limited. When long-distance transportation is required, multiple pipelines need to be connected. When connected, they are generally connected through flanges. Flanges are connected with bolts and threads. The maintenance and replacement of threaded flange connection pipelines are not convenient. Threaded connections are prone to stripping, causing the pipeline to loosen and leak.

[0003] A pipeline connection structure provided by China Publication Application No.: CN202322882576.2, the scheme is through the connection structure, the first connection pipe and the second connection pipe, when the first connection pipe and the second connection pipe are connected, the slide cylinder is manually slid so that the steel ball can move up and down in the circular hole of the first connection pipe, the front end of the second connection pipe is pushed into the inner diameter of the first connection pipe, the steel ball installed in the circular hole at the front end of the first connection pipe is clamped into the limit groove set on the outer wall of the second connection pipe, the slide cylinder is loosened, and the spring reset function is used to make the front end clamping ring of the slide cylinder press against the steel ball, and the first connection pipe and the second connection pipe of the pipeline are connected at one time. In this way, the pipeline is connected to facilitate the disassembly, assembly, maintenance and replacement of the pipeline. After the connection, the connection structure, the limit block and the outer wall of the first connection pipe form a sealing groove to ensure the sealing of the pipeline;

[0004] However, when the pipelines are connected, the pipelines may be displaced and deformed due to shaking or movement of external factors. The above scheme is not convenient for compensating for the displacement and deformation when the pipelines are displaced and deformed. The pipelines may be pulled and broken due to deformation, which is not conducive to improving the service life of the pipelines and the transportation of gas, solid and liquid substances. For this reason, we propose a corrosion-resistant and leak-proof metal compensator. Utility Model Content

The compensator body adopts an anti-corrosion coating as a whole to achieve the effect of corrosion resistance and corrosion resistance. The knob drives the two-way screw to rotate, the two-way screw drives the two screw sleeves to move relative to each other, and the screw sleeve drives the arc-shaped clamping ring to move, thereby clamping the connecting flange and the mounting flange, and then the connecting flange and the mounting flange are further sealed by the cooperation of the anti-slip strip and the sealing strip to prevent leakage.
