Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to an emergency pipeline leak plugging device. Background Art

[0002] Pipeline is a medium conveying channel widely used in industry and construction. Its main features are hard texture, strong corrosion resistance, tight interface, etc. Pipeline is widely used in factories of various industries, and the pipe network is complex. Flanges, joints, welds, etc. will inevitably produce leakage defects. When defects occur, emergency treatment is required. At present, it can only be temporarily handled by tightening flange bolts, live joints or wrapping welds with rubber skin, but these measures are less effective. Leakage defects can only be tracked and observed or equipment shutdown is requested for treatment. There is a risk of further expansion of leakage points, thus affecting the safe operation of equipment.

[0003] The current methods for dealing with pipeline leaks have the following defects: 1. Tightening flange bolts and live joints is suitable for small leaks or seepage, but may not provide sufficient sealing and safety for serious leaks or high-pressure pipelines; there may also be a small risk of leakage due to factors such as incomplete alignment, looseness or wear; and installation and maintenance require intervention in the pipeline, which may cause certain interruptions to production and operations; 2. Wrapping with rubber skin is suitable for small leaks or seepage, and is usually used to temporarily repair cracks or holes in the pipeline. For larger or serious leaks, rubber skin wrapping may not provide sufficient sealing; and the effect of the wrapping depends on the quality and adaptability of its materials. If the selected rubber skin material is not suitable for the required working environment or medium, it may not be able to effectively stop the leak; its sealing ability is limited, and it may not provide sufficient pressure resistance for high-pressure pipelines. Under high pressure conditions, stronger sealing and repair methods may be required. Utility Model Content
