Description

Technical Field

[0001] The utility model relates to the technical field of gas, in particular to a convenient leak-stopping device for gas pipelines. Background Art

[0002] In the gas pipeline network, most of the gas pipelines entering the house need to be penetrated through the wall by a through-wall pipe. However, after a period of use, the through-wall pipe will be damaged due to aging, etc., and the through-wall pipe needs to be replaced. However, during the replacement process, the gas pipeline connected to the through-wall pipe will leak gas after the through-wall pipe is removed. Gas leakage poses a safety hazard and may have adverse effects on operators and users. In order to reduce the danger of the operation and improve the overall safety level, it is necessary to adopt a mode of gas-carrying operation, direct removal, and replacement as soon as possible. However, if the through-wall pipe is removed first and then sealed, a large gas leak will still occur during the process. Announcement number CN221034621U discloses a gas pipeline plugging device, including a first splint, a second splint, a slide, a slider, and a sealing block. The other ends of the first splint and the second splint are fixedly connected by bolts; the middle of the first splint and the second splint are both provided with a slide; the slider is provided in the slide, and the slide is fixedly connected to the sealing block. A sealing groove is provided on the inner side of the sealing block, and the sealing groove is connected to the pressure gauge. The utility model provides a sliding sealing block on the first and second clamping plates, which can seal minor damage at different angles and positions on the pipeline. However, the sealing device cannot seal gas pipelines when replacing wall pipes. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a convenient leak-proof device for gas pipelines which is practical, reliable and easy to operate.

[0004] To achieve the above-mentioned purpose, the present invention provides a solution as follows: a convenient gas pipeline leak-proof device, comprising an air guide pipe, a leak-proof inflatable ball, a gas source, and a fixing member. One end of the air guide pipe is detachably connected to the leak-proof inflatable ball, and the other end of the air guide pipe is connected to the gas source. The leak-proof inflatable ball is used to be inserted into the gas pipeline, and the gas source is used to be connected to the air guide pipe. The gas source is used to supply gas to the leak-proof ball to inflate the leak-proof ball and seal the gas pipeline. The air guide pipe is provided with an on-off valve.

[0005] Among them, the fixing part includes a fixing hoop, multiple connecting rods, and a clamping sleeve. The multiple connecting rods are connected between the fixing hoop and the clamping sleeve. The fixing hoop is used to clamp and fix the gas pipeline. The clamping sleeve is installed on the gas guide pipe. A gap is left between the clamping sleeve and the outer wall of the gas guide pipe to form a material exchange groove.

[0006] The beneficial effects of the present invention are as follows: it can seal the gas pipeline when replacing the wall-penetrating pipe. The device is provided with a gas guide pipe and a leak-proof inflatable ball. When the wall-penetrating pipe needs to be replaced, the gas guide pipe and the leak-proof inflatable ball are driven to pass through the wall-penetrating pipe and are inserted into the gas pipeline. Then, gas is supplied to the gas guide pipe and the leak-proof inflatable ball through the gas source, so that the leak-proof inflatable ball expands and seals the gas pipeline. The wall-penetrating pipe is then screwed out and replaced with a new wall-penetrating pipe, thereby realizing the replacement of the wall-penetrating pipe and avoiding leakage of the gas pipeline during the replacement process. The overall structure is practical, reliable and easy to operate. At the same time, a fixing part is provided, and the gas pipeline is clamped and fixed by a fixing hoop sleeve of the fixing part. The connecting rod is connected between the fixing hoop sleeve and the clamping sleeve. In this way, the gas guide pipe can be clamped by the clamping sleeve. During the process of replacing the wall-penetrating pipe, the swing amplitude of the gas guide pipe can be limited to prevent the leak-proof inflatable ball from moving and failing to seal the gas pipeline due to excessive swing amplitude of the gas guide pipe.

[0007] Furthermore, the device further comprises a base, the leak-proof inflatable ball being mounted on the base, the outer wall of the bottom of the base being formed with a first threaded portion, the outer wall of the end of the gas guide tube being formed with a second threaded portion, and the first threaded portion being connected to the second threaded portion via a nut. The above-described structure of the utility model makes the leak-proof inflatable ball detachable, allowing replacement of leak-proof inflatable balls of different specifications to accommodate gas pipelines and wall pipes of varying diameters.

[0008] Furthermore, the leak-stopping inflatable ball is made of rubber material. After the utility model adopts the above structure, the leak-stopping inflatable ball can be expanded.

[0009] Furthermore, the air guide tube is made of metal material. After the utility model adopts the above structure, the air guide tube has sufficient hardness and can be well extended into the designated position of the wall-penetrating pipe.

[0010] Furthermore, the air guide tube is provided with a joint, and the joint is used for detachably connecting to the air source.

[0011] Furthermore, the air guide pipe is provided with a telescopic section, the telescopic section includes a telescopic sleeve and a telescopic tube, the telescopic tube slides in the telescopic sleeve, the telescopic sleeve is connected to the switch valve, and the telescopic tube is connected to the joint.

[0012] Furthermore, the fixing hoop includes two clamping members, which are symmetrically arranged on the left and right, and clamp the gas pipeline together, wherein the clamping members are connected to at least one connecting rod.

[0013] Furthermore, the two ends of the clamping member are respectively formed with connecting plates, and the connecting plates are provided with connecting holes, and the connecting holes of the two clamping members are sequentially screwed to connect and fix the two clamping members. After adopting the above structure, the utility model can be clamped on the gas pipeline.

[0014] Furthermore, the clamping member has a semicircular arc structure.

[0015] Furthermore, the air source is an electric air pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See attached Figure 1 To the attached Figure 4As shown, a convenient leak-plugging device for gas pipelines includes an air guide tube 1, a leak-plugging inflatable ball 2, a base 21, a gas source 3, and a fixing part. One end of the air guide tube 1 is detachably connected to the leak-plugging inflatable ball 2, and the other end of the air guide tube 1 is connected to the gas source 3. The leak-plugging inflatable ball 2 is used to be inserted into the gas pipeline 51, and the gas source 3 is used to be connected to the air guide tube 1. The gas source 3 is used to supply gas to the leak-plugging ball to expand and seal the gas pipeline 51. A switch valve 11 is provided on the air guide tube 1.

[0024] Among them, the fixing parts include a fixing hoop, multiple connecting rods 42, and a clamping sleeve 43. Multiple connecting rods 42 are connected between the fixing hoop and the clamping sleeve 43. The fixing hoop is used to clamp and fix the gas pipeline 51. The clamping sleeve 43 is mounted on the gas guide pipe 1. A gap is left between the clamping sleeve 43 and the outer wall of the gas guide pipe 1 to form a material exchange groove 431.

[0025] In this embodiment, the leak-proof inflatable ball 2 is set on the base 21, the outer wall of the bottom of the base 21 is formed with a first threaded portion, and the outer wall of the end of the air guide tube 1 is formed with a second threaded portion 12, and the first threaded portion is connected to the second threaded portion 12 by a nut 23.

[0026] In this embodiment, the leak-stopping inflatable ball 2 is made of rubber material; and the air guide tube 1 is made of metal material.

[0027] In this embodiment, the air duct 1 is provided with a connector 13 , which is used for detachably connecting to the air source 3 .

[0028] In this embodiment, the air duct 1 is provided with a telescopic section, which includes a telescopic sleeve 141 and a telescopic tube 142 . The telescopic tube 142 slides in the telescopic sleeve 141 . The telescopic sleeve 141 is connected to the switch valve 11 , and the telescopic tube 142 is connected to the joint 13 .

[0029] In this embodiment, the fixing hoop includes two clamping members 41, which are symmetrically arranged on the left and right. The two clamping members 41 jointly clamp the gas pipeline 51, wherein the clamping members 41 are connected to at least one connecting rod 42; connecting plates 412 are respectively formed at both ends of the clamping member 41, and connecting holes 413 are opened on the connecting plates 412. The connecting holes 413 of the two clamping members 41 are screwed in sequence to connect and fix the two clamping members 41; the clamping member 41 has a semicircular arc structure.

[0030] In this embodiment, the wall-penetrating pipe 52 is connected to the gas pipeline 51. The specific plugging process is as follows: when the wall-penetrating pipe 52 needs to be replaced, the clamping sleeve 43 is first put on the gas guide pipe 1, and then the fixed hoop is clamped to the gas pipeline. The two clamping members 41 are respectively clamped to the gas pipeline 51, and the connecting plates 411 of the two clamping members 41 are butted together. Screws are sequentially passed through the connecting plates 411 of the two clamping members 41 to achieve connection and fixation of the two clamping members 41, thereby clamping and fixing the fixed hoop to the gas pipeline 51.

[0031] At this time, the gas guide tube 1 can be pushed to insert the leak-proof inflatable ball 2 into the wall-penetrating tube 52, and then continue to insert until the leak-proof inflatable ball 2 enters the gas pipeline 51 through the wall-penetrating tube 52. Then, according to the actual working scenario, the length of the gas guide tube 1 can be adjusted. Specifically, the telescopic tube 142 is pulled to move, so that it slides in the telescopic sleeve 141 until it slides to the set position, so that the telescopic section is extended to the set length.

[0032] At this time, the gas source 3 in this embodiment is an electric air pump. The electric air pump is connected to the connector 13 and then started to inflate the leak-proof inflatable ball 2 through the gas guide tube 1, causing the leak-proof inflatable ball 2 to expand until the leak-proof inflatable ball 2 blocks the gas pipeline 51. A gas leak measuring instrument is then used to measure whether there is any leakage at the leak-proof inflatable ball 2.

[0033] If there is no leakage, close the switch valve 11 and disassemble the electric air pump. Since the fixed fixing hoop is connected to the clamping head 43 through multiple connecting rods 42, it can be mounted on the gas pipe 1 through the clamping sleeve 43 to limit the swing amplitude of the gas pipe 1 after the leak-blocking inflatable ball 2 blocks the gas pipeline 51, thereby reducing the gas leakage at the plugging point between the leak-blocking inflatable ball 2 and the gas pipeline 51. At this time, the wall-penetrating tube 52 can be screwed out to screw out the wall-penetrating tube 52, and then the wall-penetrating tube 52 is driven to move on the gas pipe 1 and pass through the material replacement groove 431 until the wall-penetrating tube 52 is taken out from the joint 13 of the gas pipe 1, and then a new wall-penetrating tube 52 is replaced and inserted into the gas pipe 1 from the joint 13. Finally, the new wall-penetrating tube 52 is screwed back into the connected gas pipeline 51 to complete the replacement of the wall-penetrating tube 52 and avoid gas leakage in the gas pipeline 51 during the replacement process.

[0034] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any person skilled in the art may, without departing from the scope of the present invention, utilize the technical content disclosed above to make further possible variations and modifications to the present invention, or to modify the present invention into equivalent embodiments with equivalent variations. Therefore, any equivalent variations made in accordance with the principles of the present invention without departing from the scope of the present invention shall be included within the scope of protection of the present invention.
