Problems solved by technology

[0005] Although the above-mentioned devices can solve the problem of plugging gas pipelines with large diameters under the condition of high gas pipeline pressure or high gas temperature, these devices are only suitable for plugging leaks at the side of the pipeline. There is no way to deal with leaks at the shelf
The known methods for repairing the leaks at the brackets of the gas pipelines are emergency measures such as smearing sealant, cold welding and sticking to repair and stop the leaks. Waste of materials, leakage occurs again at the plugging and repairing point, which brings safety hazards to normal production and even leads to production shutdown
[0006] Therefore, there are above-mentioned inconveniences and problems in the known plugging device and method of gas pipeline socket bracket.

Embodiment 1

[0032] see now Figure 1 to Figure 4 , figure 1 It is the front view of the hoop-type leak-stopping device according to the embodiment of the present invention, figure 2 for figure 1 The sectional view of A-A in, image 3 for figure 2 Enlarged view of B in the figure, Figure 4 It is a schematic diagram of the expanded structure of the hoop-type leak-stopping device according to the embodiment of the present invention.

[0033] A hoop-type leak plugging device for leakage at the bracket of a gas pipeline pipe seat, comprising a first hoop piece and a second hoop piece, characterized in that:

[0034] The first hoop piece is provided with a first arc plate 1 and a second arc plate 2, the arc of the first arc plate matches the arc of the gas pipe 7, and two pairs of the first arc plate are symmetrically arranged The tie bar 3, said tie bar is a flat steel bar made of flat steel, one end of the tie bar is welded to the first arc plate, the other end is welded with a bolt ...

Embodiment 2

[0039] A method for using a hoop-type leak plugging device for leakage at the bracket of a gas pipeline pipe seat, which is characterized in that it includes the following steps:

[0040] a. Make the first hoop piece and the second hoop piece. According to the actual situation of the diameter of the gas pipe on site, the arc plate of the pipe seat bracket and the slot 10 of the five bracket ribs, make the first hoop with the corresponding arc. 1 hoop sheet and the 2nd hoop sheet, make the bracket rib slit 10 on one side of the 2nd arc plate match the bracket rib number and size.

[0041] b. Provide PSI quick-forming steel glue sticks, polytetrafluoroethylene elastic belts and refractory mud materials for plugging. PSI quick-forming steel glue stick is a steel-reinforced repair agent that can fill leaks, cracks, sand holes, defects, fractures, damages, etc. on containers, pipes, and some parts of metal materials such as steel, iron, and aluminum with bonding. In addition, PSI...

Abstract

The invention discloses a hoop type plugging device for leakage at pipe seat brackets of gas pipelines. The hoop type plugging device comprises a first hoop sheet and a second hoop sheet, and is characterized in that the first hoop sheet is provided with a first arc plate (1) and a second arc plate (2); the second hoop sheet is provided with a first arc plate (1) and a second arc plate (2), the first hoop sheet is opposite to the second hoop sheet, bracket rib plate insertion gaps (10) of the second arc plates of the first hoop sheet and the second hoop sheet are correspondingly arranged, and plates (4a) with bolt holes and plates (4b) with bolt holes are fastened and connected with one another by bolt assemblies (6). The hoop type plugging device for the leakage at the pipe seat brackets of the gas pipelines and a method for applying the hoop type plugging device has the advantages of simple structure, convenience in manufacture and operation, simple plugging process, low cost and good plugging effect.

Description

technical field [0001] The invention relates to a plugging device for leakage of a gas pipeline, in particular to a hoop type plugging device for leakage at a bracket of a pipe seat of a gas pipeline and a usage method thereof. Background technique [0002] Due to the harsh environment of the coke oven gas pipeline in the coking plant, after a long period of use, there will be severe corrosion at the bottom of the gas pipeline, and leaks will appear at the bracket of the gas pipeline on the upper part of the concrete column. [0003] Chinese patent CN 201606621U disclosed a gas pipeline plugging device on October 13, 2010, including a truncated cone type plug, a fixed hook including an elastic barb and a needle rod, and an outer hook is provided at the tail end of the needle rod. screw thread, the frustum-cone type plug is sleeved on the needle shaft through its central through hole, and a retaining ring is set on the needle shaft for axial positioning of the frustum-type pl...
