Embodiment Construction

[0045]The present invention differs from the prior art in the following key points: 1: Utilize the arc-shaped compression block to press the sealing rubber pad with grid-like sealing strips to block the leaking part of the pipeline, and seal the surface of the pipeline around the leaking part to form a multi-layer multi-layer The sealing method of the pipeline makes the present invention suitable for sealing large-area leakage, cracks or perforations of medium and high pressure pipelines, and has good adaptability to pipeline deformation deviation and good sealing reliability. 2: The unique design of the assembled rigid arc-shaped frame, the adjustable combined arc-shaped pressing block, the grid-shaped sealing strip sealing rubber pad, and the flexible sling binding and fixing makes the present invention light in weight and compact in structure. Simple and flexible, easy and labor-saving installation and adjustment, convenient for land and underwater sealing construction.

Abstract

The invention discloses a pipeline maintenance and first-aid repair pipe clamp. The pipeline maintenance and first-aid repair pipe clamp comprises two arc-shaped frames, arc-shaped frame connecting end blocks, arc-shaped pressing blocks, sealing rubber pads, arc-shaped frame rubber pads, elastic universal supporting assemblies, two flexible cables, a plain hole connecting block assembly, a screw hole connecting block assembly and connecting bolts. The pipeline maintenance and first-aid repair pipe clamp is suitable for quick plugging of large-area leakage and cracks or penetrating holes of middle-high pressure pipelines and suitable for large pipeline deviation and deformation. The leakage plugging success rate is high, the weight is low, installation and adjustment are easy and convenient, and underwater construction is facilitated for divers.

Description

technical field [0001] The present application relates to the field of pipeline maintenance, in particular to a pipe clip for pipeline maintenance and emergency repair. Background technique [0002] Mechanical pipeline maintenance and repair pipe clamps are widely used in maintenance and emergency repair operations such as corrosion perforation, weld cracks, and accidental damage with little damage, because they do not require welding during the plugging process and the construction speed is fast. [0003] The current mechanical pipeline maintenance clamps generally adopt a sealed cavity structure, that is, two semicircular and half clamps are connected into one body through bolts, and the space between the two half clamps is sealed by an axial sealing strip, which is set at the leakage of the pipeline. The gap between the end and the pipeline is sealed by a circumferential sealing strip, and an annular sealing cavity is formed at the leak to realize the sealing of the pipel...
