Abstract

The utility model relates to a pipeline leak-stop clip, which comprises a U-shaped screw bolt 1, a fastening body 5, and a screw nut 2. A setting off pad 2 at the bending inner edge of the screw bolt, an upper rubber pad 3 and the fastening body 5 are connected in series on a screw bolt rod. The inner edge of the screw bolt is a concave curved face, and a lower rubber pad 4 is arranged on the inner edge. A gasket 6 and the screw nut are arranged on the outer screw rod of the fastening body. The utility model has especially conspicuous effect of quick leakage protection for the leakage ports and the seepage ports of the pipeline, with the advantages of simple structure, convenient maintenance, and low cost.

Description

A kind of pipe plugging folder

The utility model relates to a kind of blocking pipe race and emits the folder of leakage, belongs to the component that the maintenance pipeline is used.

Present water in factory or civil building, pipelines such as vapour are more, because pipeline quality difference or use pipeline generation corrosion to make pipeline often occur running for a long time, emit, drip, leak, phenomenon such as ooze, as handle untimely enterprise or the resident family of giving and bring economic loss, sometimes even because of pipe leakage human casualty accident seriously appears, existing common maintenance blocking method is to twine the mending-leakage hole or with two and half garden shape clamps with the rubber bar, two ends have fixing bolt to be fixed the realization leak stopping, but inconvenience when these class methods and clamp maintenance, sometimes leak stopping is uncertain, poor effect does not still have leak stopping parts preferably at present.

Task of the present utility model provides a kind of pipe plugging folder, and it is simple in structure, and maintenance operation is convenient, plugging effect is good, cheap.

For solving above-mentioned task, the solution that the utility model adopts is: comprise a U bolt and wear fastener and the nut that is connected on the bolt shank, be lined with pad and rubber cushion at bolt curved part inner edge, also be lined with rubber cushion at the fastener inner edge, nut is in the screw rod end.

Below in conjunction with drawings and Examples the utility model is described in further details.

Accompanying drawing is the utility model cross-sectional view.

Among the figure, rubber cushion on 1U type bolt, 2 pads, 3,4 times rubber cushions, 5 fasteners, 6 packing rings, 7 nuts, 8 pipelines.

The pipe plugging folder comprises U bolt 1 and the company's of wearing fastener 5 thereon and two nuts 7 of bolt end as shown in FIG., curved part inner edge at bolt is lined with the metal pad 2 of corresponding lonely degree and seals rubber cushion 3, at fastener 5 inner edges the depression of corresponding curvature and the following rubber cushion 4 that is complementary are with it arranged, packing ring 6 and nut 7 are arranged on the fastener outside screw rod.

The pad 2 of the curved part of U bolt 1 and liner can be used stitch bonds in the utility model, pad and last rubber cushion 3 interconnect successively and are one, fastener 5 inner edges can be bonded as one with following rubber cushion, like this in actual maintenance operation, can stop up fast during anxious the repairing of particularly anxious leakage and Lou ooze the place, and can form this series folder according to the different-diameter of pipeline 8.

The utility model when finding that pipeline 8 has the run, drip, leak position, can block up the last rubber cushion position of corresponding leak stopping folder in leak in use, fastener and following rubber cushion is affixed on the pipeline 8 again, adds packing ring again and nut is fastened on the pipeline.The utility model is simple in structure, and mending-leakage is certain, is specially adapted to suddenly repair leakage pipe, and effect spy is good.

Claims

1. pipe plugging folder, it comprises U bolt and nut and fastener, it is characterized in that: at the curved part liner dress metal pad and the last rubber cushion of bolt, at the fastener inner edge of cross-under on the bolt shank rubber cushion under depression curved surface and the liner is arranged.

2. pipe plugging folder according to claim 1 is characterized in that: bolt curved part and liner pad and last rubber cushion mutually combine and are one, the bonding one of rubber cushion under fastener and the liner.
