Problems solved by technology

[0005] Although the above-mentioned devices can solve the problem of plugging gas pipelines with large diameters under conditions of high gas pipeline pressure or high gas temperature, these devices are only suitable for plugging leaks at the side of the pipeline. Leaks can't be dealt with
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 repairing method of leakage at the known gas pipeline tee fitting place

Embodiment 1

[0035] see now Figure 1 ~ Figure 3 , figure 1 It is a schematic diagram of the unfolded structure of the hoop-type leak-stopping device according to the embodiment of the present invention, figure 2 It is the front view of the hoop-type leak-stopping device according to the embodiment of the present invention, image 3 It is a top view of the hoop-type leak-stopping device according to the embodiment of the present invention. As shown in the figure, the first arc plate 2 is matched with the gas tee main pipe 8, and its length is twice the diameter of the branch pipe 9. There are four tie bars arranged side by side along the edge of the arc plate on one side of the main pipe 8. 3. One end of the tie bar 3 is solidly welded with the first circular arc plate 2, and the other end is welded with bolt hole plates 4a, 5b; Two tie bars 3 are arranged side by side on the edge of the plate, one end of the tie bar is welded with the first arc plate 2, and the other end is welded wit...

Embodiment 2

[0040] A method for using a hoop-type leak plugging device for leakage at a tee pipe fitting of a gas pipeline, which is characterized in that it includes the following steps:

[0041]a. Pre-fabricated hoop-type plugging device used for leakage at the tee fittings of gas pipelines

[0042] According to the diameter of the gas pipeline, a hoop-type plugging device for leakage at the tee fittings of the gas pipeline is pre-processed. The first circular arc plate 2 is matched with the gas tee main pipe 8, and the length is 9 diameters of the branch pipe. 2 times, it is provided with 4 tie bars 3 side by side along the edge of the arc plate on one side of the main pipe 8, one end of the tie bars 3 is solidly welded with the first arc plate 2, and the other end is welded with bolt hole plates 4a, 5b; The middle of the other side is provided with a concave arc, and two tie bars 3 are arranged side by side on the edges of the arc plates on both sides of the branch pipe 8, one end of ...

Abstract

A hoop leakage stoppage device for stopping leakage of tee joint pipes of a gas conduit comprises a first arc plate (2) and a second arc plate (6) and is characterized in that the first arc plate (2) is matched with a gas conduit tee joint main pipe (8), the length of the first arc plate (2) is larger than the diameter of a branch pipe (9), the second arc plate (6) is matched with the gas conduit tee joint branch pipe (9) and parallelly provided with a plurality of pulling ribs (3) along edges of arc plates on two sides of the branch pipe (9), a concave arc of the first arc plate (2) is connected with a convex arc of the second arc plate (6) through welding, and teflon seal gaskets are arranged on the first arc plate and the second arc plate. The hoop leakage stoppage device for stopping leakage of the tee joint pipes of the gas conduit and a use method of the hoop leakage stoppage device have the advantages of being simple in structure, convenient to manufacture and, simple in leakage stopping method, and convenient to operate.

Description

technical field [0001] The invention relates to a plugging device for gas pipeline leakage, in particular to a hoop-type leak plugging device for gas pipeline tee fitting leakage and its application method. 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 CN201606621U disclosed a gas pipeline plugging device on October 13, 2010, including a truncated cone plug, a fixed hook including an elastic barb and a needle rod, and the tail end of the needle rod is provided with an external thread , the truncated cone-shaped plug is sleeved on the needle shaft through its central through hole, and a stop ring is set on the needle shaft for axially positioning the truncated-cone type plug, A nut threadedly connec...
