Description

A pressure pipe leak plugging jig

Technical field

The utility model relates to a leak-stopping tool, in particular to a leak-stopping jig for pressure pipelines.

Background technique

During the operation of long-distance gas pipelines, acidic liquid may accumulate in low-lying areas of the pipeline, or partial damage to the anti-corrosion layer of the pipeline may lead to corrosion and perforation of the pipeline, which requires leakage repair. If the gas is shut down and the leak is repaired by welding, a large amount of natural gas will be vented, resulting in certain economic losses. Therefore, in the current long gas pipeline gas transmission process, if the pipeline is perforated and leaks, usually the pressure pipeline is used to plug the leak. The clamp is used to plug the leak. The existing pressure pipe leak plugging fixture adopts double arc plate and double bolt connection, as shown in Figure 1, which includes an upper pipe clamp, a lower pipe clamp and a plugging bolt arranged on the upper pipe clamp or the lower pipe clamp. When the pipeline is perforated, clamp the upper pipe clamp and the lower pipe clamp on the gas pipeline, and adjust the position so that the plugging bolt is aligned with the leak point, and then rotate the bolt to tighten the leak point, so as to achieve the purpose of plugging. Although such a structure can carry out plugging operation during pipeline gas transmission, and can avoid the economic loss caused by gas stop or emptying the pipeline, the inventors of the present application have found that the leak-stopping jig with the above-mentioned structure still exists. The problem is specifically reflected in: when aligning the plugging bolts with the leak point, it is necessary to rotate the entire plugging jig as a whole, and the plugging jig itself is large in size and heavy in weight, especially for large-diameter air pipes. The operation of the whole set of clamps is very difficult, so in the current gas pipeline plugging construction, it takes a lot of time and manpower to locate the leak point.

Therefore, based on the above, there is an urgent need for a pressure pipe leak plugging jig that can quickly locate leak points, reduce the labor intensity of construction personnel, and save the construction time of leak plugging.

Contents of the invention

The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, and provide a pressure pipeline plugging jig that can quickly locate the leak point, reduce the labor intensity of construction personnel, and save the construction time of plugging.

A leak-stopping jig for a pressure pipeline includes a clamping piece matched with a gas pipeline, a chute is provided on the clamping piece, and a leak-stopping piece for blocking the perforation of the pipeline is slidably arranged in the chute. The leak plugging jig of the present application, when performing leak plugging work, firstly, according to the position of the leak point, the clamping piece is correspondingly arranged on the gas pipeline, and after the clamping piece is fixed, the leak point is positioned by sliding the leak plugging piece , so that when locating the leak point, it is not necessary to turn the jig as a whole, but only need to slide the plugging piece, which not only saves time, but also reduces the labor intensity of workers.

As a preferred solution of the present application, the clamping member includes an upper pipe clamp, a lower pipe clamp, a hinge bolt used to hinge the upper pipe clamp and the lower pipe clamp, and a double-ended screw used to tighten the upper pipe clamp and the lower pipe clamp. Columns and nuts. Both the upper pipe clamp and the lower pipe clamp are provided with chute, and the chute is equipped with a plugging piece that can slide along the chute.

Preferably, the plugging member includes a slider slidingly arranged in the chute, a push rod is threadedly connected to the slider, a circular rubber pad is attached to the inner end of the push rod, and the push rod is along the The radial direction of the gas pipeline runs through the slider. When locating the leak point, slide the plugging piece to find the leak point. After finding the leak point, align the circular rubber pad attached to the inner end of the push rod to the leak point. Rotate the ejector rod until the circular rubber pad presses against the leak point to achieve the effect of plugging.

Preferably, the chute is arranged with one or more leak-stopping parts, which can realize the leak-stopping of one or more leak points.

Preferably, an arc-shaped rubber pad is pasted on the inner wall of the clamping part composed of the upper pipe clamp and the lower pipe clamp, which can protect the pipeline anti-corrosion layer when the clamp moves.

Compared with the prior art, the utility model has the beneficial effects: the utility model can quickly locate the leak point without moving the main body of the jig, but only moves the slider, reduces the labor intensity of construction personnel, and saves construction time for plugging.

Beneficial effects of other embodiments of the present application: one or more leak points can be plugged at the same time.
