[0002] When repairing existing gas pipelines, it is usually necessary to seal the pipe opening of the gas pipeline. Usually, an inflatable airbag is inserted into the pipe opening, and the airbag is inflated to expand the airbag to fit the inner wall of the pipe to achieve a sealing effect.

[0003] However, the friction between the existing airbag and the inner wall of the pipe is not large enough, and there is still a certain pressure inside the pipe. The airbag is not stable after installation. If the pressure inside the pipe changes, the airbag will shift or fall off and fail to seal. Utility Model Content

[0004] The purpose of the utility model is to provide a gas pipeline repair and plugging device, which is used to solve the problem that the existing air bag used for plugging the gas pipeline is easily displaced or falls off.

[0005] To address the aforementioned issues, the present invention provides a gas pipeline repair and plugging device, comprising an airbag positioned at the opening of a gas pipeline. An ellipsoidal ball is positioned within the airbag, a gas pipe fixedly connected to the ellipsoidal ball. A connecting pipe is fixedly connected to one end of the airbag, which in turn is fixedly connected to the connecting pipe. The end of the gas pipe, distal to the connecting pipe, extends beyond the ellipsoidal ball and is positioned within the airbag. A sleeve is fitted over the connecting pipe, a curved cover fixed to one end of the sleeve. The curved opening of the curved cover contacts the airbag. A support ring is fixed to the edge of the curved cover via multiple connecting rods. The support ring has multiple slide grooves arranged in an annular array. Sliders are slidably connected within the slide grooves. An arc-shaped block is fixed to the ends of the multiple slides distal to the arc-shaped block. A first anti-slip pad is fixed to the curved block, which can contact the inner wall of the gas pipeline.

[0006] The gas pipeline repair and blocking device provided by the utility model also has the following technical features:

[0007] Furthermore, one end of the air pipe away from the connecting pipe is fixedly connected to an arc-shaped shunt pipe.

[0008] Furthermore, a sliding ring is slidably connected to the sleeve, and a plurality of supports corresponding to the sliders are fixed on the sliding ring, and a support rod is hinged between the corresponding sliders and the supports via a rotating shaft.

[0009] Furthermore, a screw sleeve is threadedly connected to the sleeve, and one end of the screw sleeve is in conflict with a plurality of supports.

[0010] Furthermore, an annular cover is fixed to one side of the branch ring extending out of the gas pipeline, and a plurality of vertical grooves arranged in an annular array are provided on the annular cover, a clamping block is slidably connected in the vertical groove, a second anti-slip pad is fixed to one end of the clamping block, and an arc-shaped surface is provided at the other end of the clamping block.

[0011] Furthermore, a rotary cover is fixed on the screw sleeve, and one side of the rotary cover is provided with an arc surface corresponding to the arc surface of the clamping block, and the arc surface of the rotary cover contacts the arc surface of the clamping block.

[0012] The utility model has the following beneficial effects: when the pipeline needs to be repaired, the airbag is placed in the pipe mouth of the gas pipeline, and the elliptical ball plays a supporting role, which makes it easy to place the airbag. After installing the inflation joint on the pipe, the pipe can be inflated, and the elliptical ball occupies a certain space, which can reduce the inflation amount, thereby increasing the inflation speed, so that the airbag expands to fit and conflict with the inner wall of the gas pipeline, achieving a sealing effect, and the arc mouth of the arc cover contacts with the airbag, and by sliding multiple sliders toward the end away from the arc cover, the first anti-slip pad on the arc block can conflict with the inner wall of the gas pipeline, thereby fixing the relative position between the arc cover and the gas pipeline, and the arc cover can limit the airbag, and if the internal pressure of the gas pipeline changes, the airbag is prevented from shifting or falling off.

When the pipeline needs to be repaired, the airbag 2 is placed in the pipe mouth of the gas pipe 1. The elliptical ball 3 plays a supporting role, which makes it easier to place the airbag 2. After installing the inflation connector on the connecting pipe 5, air can be inflated into the connecting pipe 5. The elliptical ball 3 occupies a certain space, which can reduce the inflation amount, thereby increasing the inflation speed, so that the airbag 2 expands to fit and conflict with the inner wall of the gas pipe 1, achieving a blocking effect. The arc mouth of the arc cover 7 contacts the airbag 2, and by sliding multiple sliders 10 toward the end away from the arc cover 7, the first anti-slip pad on the arc block 11 can conflict with the inner wall of the gas pipe 1, thereby fixing the relative position between the arc cover 7 and the gas pipe 1. The arc cover 7 can limit the airbag 2. If the internal pressure of the gas pipe 1 changes, the airbag 2 is prevented from shifting or falling off.

[0019] In one embodiment of the present application, preferably, the end of the trachea 4 away from the connecting pipe 5 is fixedly connected to an arc-shaped shunt pipe 12. The provision of the shunt pipe 12 can reduce the impact force of the airflow on the airbag 2 during inflation.

A support rod 15 is hinged between the corresponding sliders 10 and the supports 14 via a rotating shaft. By moving the sliding ring 13, the support rod 15 can be pressed against the slider 10, so that the first anti-slip pad on the arc block 11 contacts the inner wall of the gas pipeline 1.

The elliptical ball 3 occupies a certain space, which can reduce the inflation amount, thereby increasing the inflation speed, so that the air bag 2 expands to fit and conflict with the inner wall of the gas pipeline 1, achieving a blocking effect. By moving the sleeve 6, the arc mouth of the arc cover 7 is in contact with the air bag 2, and the screw sleeve 16 is rotated to drive the sliding ring 13 to move The arc cover 7 and the gas pipe 1 are fixed relative to each other, so that the screw sleeve 16 and the sleeve 6 rotate relative to each other, thereby driving the rotary cover 19 to move, so that the arc surface of the rotary cover 19 contacts the arc surface of the clamping block 18, and then driving the clamping block 18 and the corresponding second anti-slip pad to clamp the outer surface of the gas pipe 1.
