Description
Technical Field
The utility model relates to a pipeline repairing clamp, in particular to a pipeline plugging clamp.
Background
After the long-distance pipeline is built and put into use, the outer layer of the pipeline can be corroded or leaked after long-term wind and sun exposure. When problems occur in pipeline valves, as the traditional clamp of the type adopts an inner-outer sleeve welding mode, the height of the inner cavity of the clamp is limited, and for valves with larger diameters, the sealing effect can be realized only by increasing the diameter of the outer sleeve. Therefore, the weight of the plugging clamp is increased, and the quick on-site rush repair is not facilitated.

The utility model aims at realizing the following technical scheme:
The pipeline leakage blocking clamp comprises a reinforcing ring and a barrel, wherein the barrel in the leakage blocking clamp is integrated, a sealing gasket is arranged at the contact part of the bottom of the reinforcing ring and a pipeline, a pipeline valve joint is welded and fixed with an upper cover plate, and a sealing cavity is formed by welding the pipeline valve joint and the barrel; two chain supports are welded on the outer side of the cylinder body and used for fixing a screw rod and a chain combination; a support reinforcing rib is welded below the chain support; the sealing gasket is arranged at the bottom of the cylinder body for sealing; the valve is connected with the oil pipe joint through threads and then is arranged on the valve joint through threads; the elliptical end socket is welded at the top end of the cylinder; the reinforcing ring is welded on the pipeline.
The pipeline leakage blocking clamp is arranged on a pipeline at a leakage position, and a clamp sealing ring is uniformly contacted with the pipeline. The utility model has the advantages and effects that:
The utility model relates to a quick plugging rush-repair fixture aiming at the conditions of larger valve diameter, higher valve diameter and the like at a leakage position. The method is used for improving the rapidity, practicality and convenience of plugging and repairing. Through the improvement to fixture structure, increase fixture inside minimum diameter and inner chamber height. Meanwhile, the screw rod chain fastening device is adopted to fix the clamp at the pipeline, so that quick plugging emergency repair is realized when the conditions of larger diameter, higher diameter and the like of the valve at the leakage position occur. The quick rush repair of the condition that the diameter of the valve at the leakage position is large and the height is high is solved. Compared with the traditional clamping apparatus of the type, the clamping apparatus has wider application range.

Detailed Description
The present utility model will be described in detail with reference to the embodiments shown in the drawings.
The pipeline plugging fixture is applied to the conditions of larger valve diameter and higher height at the place of leakage, and requires that the working pressure of a pipeline is not more than 15MPa and the highest working temperature is not more than 120 ℃. Pipeline specifications phi 159-phi 1422.
The utility model relates to a pipeline plugging clamp which comprises a reinforcing ring 1 and a cylinder body 2, wherein the cylinder body in the reinforcing ring 1 is integrated, a sealing gasket is arranged at the contact part of the bottom of the clamp and a pipeline, and the clamp is fastened by a rotary fastening device.
The valve joint 5 is welded and fixed with the upper cover plate 4 and then welded with the cylinder 2 to form a sealed cavity; two chain supports 10 are welded on the outer side of the cylinder 2 and serve as fixed screw-chain combinations 12; to prevent the chain support 10 from deforming, support reinforcing ribs 11 are welded below it; the sealing gasket 3 is made of nitrile rubber and is arranged at the bottom of the cylinder 2 to play a sealing role; the valve 6 and the oil pipe joint 7 are installed together through threaded connection and then installed on the valve joint 5 through threaded connection, so that a drainage effect is achieved; the elliptical seal head 8 is welded at the top end of the cylinder body, so that later-stage corrosion prevention is facilitated; the reinforcing ring 1 is welded on the pipeline and plays a role in reinforcing.
When the leakage position is found, the valve 6 of the leakage stopping clamp is opened, the leakage stopping clamp is placed on a pipeline at the leakage position, and the leakage stopping clamp is finely adjusted to enable the sealing ring of the clamp to be in uniform contact with the pipeline. And a screw rod-chain combination 12 is arranged, and the two screw rods are rotated to achieve the function of fastening the sealing ring of the clamp. And then the clamp is used for plugging the leakage position with the sealing ring. And after confirming that the clamp is free of leakage, maintaining the pressure. And (3) after pressure maintaining, welding the intersecting line weld joint, and then welding the reinforcing ring 1 on the pipeline. And finally, closing the valve 6, removing the oil pipe joint 7, and welding the elliptical seal head 8, thereby effectively repairing the pipeline leakage.
