Problems solved by technology

However, since the chain cannot be adjusted continuously, it is difficult to ensure the clamping force on the seal
[0006] The mechanical blockage emergency treatment technology has the following advantages: 1. No need to reduce pressure, and does not affect the user's gas supply; 2. The hot work is controllable and improves the safety factor; but it also has the following disadvantages: 1. The operation time is long; 2. , higher requirements for working space; 3, higher labor intensity
In the case of minor leaks in the general gas operation process, the cost of using this technology is relatively high, and the construction time is relatively long

Embodiment 1

[0054] Such as figure 1 , 3 , 4, 5, 6, 7, and 8, refer to figure 1 , A self-protected leak plugging device under pressure of the present invention includes a clamp 2, a plugging plate 3, and a chain 4. The clamp 2 is clamped on the pipeline 1 through the chain 4 to clamp the plugging plate 3, and the clamp 2 uses a screw structure to tighten Tighten the chain 4, and the plugging plate 3 uses a ball lock structure to reduce the pressure on the plugging plate 3 at the leak of the pipeline 1.

[0055] See image 3 The fixture 2 includes a screw 21, a lifting plate 22, a sprocket 221, a guide rail 23, an upper cross frame 231, a lower cross frame 232, and a base 24. The fixture 2 is clamped on the pipe 1 through the base 24, and the base 24 is fixed by A frame composed of a lower horizontal frame 232, a longitudinal guide rail 23, and an upper horizontal frame 231. The upper horizontal frame 231 and the lower horizontal frame 232 are rotatably connected to the upper and lower ends of ...

Embodiment 2

[0074] Such as figure 2 As shown, the difference between the second embodiment and the first embodiment is that a self-protected leak-off device with pressure is used to repair the pipeline when the leak-off plate 3 is rotated 180° in the circumferential direction and the space is relatively narrow, including the following steps:

[0075] A. Thread the valve 32 of the plugging plate 3 with the adapter 33, and screw down the bolt 34 in the middle of the adapter 33, so that the bolt 34 presses down on the sealing ball 321 to open the ball lock;

[0076] B. Place the middle part of the plugging plate 3 at the leak of the pipeline 1;

[0077] C. Clamp the two sets of clamps 2 with the chain grooves of the plugging plate 3 at the same side position as the leakage of the pipeline 1;

[0078] D. Use the sprocket 221 to fix both ends of the chain 4, and the chain 4 fixes the plugging plate through the chain groove of the plugging plate 3;

[0079] E. Tighten the screw 21 to raise the lifting p...

Abstract

The invention discloses a self-protected under-pressure leakage plugging device and a method for rushing to repair a pipeline by using the self-protected under-pressure leakage plugging device, and relates to a pipeline leakage plugging device, in particular to a leakage plugging plate and a clamp for plugging leakage of a gas pipeline, as well as a rushing-to-repair method, and aims to provide a self-protected under-pressure leakage plugging device which is simple in structure, low in cost, simple and convenient to operate, high in environment adaption property and high in leakage plugging sealing property, does not need to stop pipeline conveying and can ensure the hooping force. The self-protected under-pressure leakage plugging device comprises a clamp (2), a leakage plugging plate (3) and a chain (4), wherein the clamp (2) is used for hooping the leakage plugging plate (3) through the chain (4) on a pipeline (1); the clamp (2) is used for tightening the chain (4) by virtue of a screw rod structure; the pressure at a leakage part of the pipeline (1) to the leakage plugging plate (3) is reduced by virtue of a ball locking structure.

Description

Technical field [0001] The invention relates to a pipeline plugging device, in particular to a plugging plate and fixture used for plugging a gas pipeline, and a method for repairing the pipeline by using the plugging plate and clamp. Background technique [0002] At present, the existing pressure plugging technology at home and abroad can be divided into two types, fixed fire plugging and hot plugging. [0003] According to the different technical principles and methods, immovable fire plugging can be divided into injection-type leak-stopping technology under pressure, pressure-bonding sealing technology, and pressure-topping sealing technology. The immovable fire plugging technology mainly refers to welding technology, which does not use open flame during the operation process, and has the advantages of safety, reliability, and easy operation. However, considering that the gas transmission and distribution pipelines are made of metal, the immobilized fire plugging technology can...
