Description

Technical Field

[0001] The utility model relates to the field of gas engineering, in particular to a pipeline plugging device for gas engineering installation. Background Art

[0002] Gas engineering refers not only to natural gas engineering, but also includes liquefied petroleum gas, coal-to-gas and heavy oil cracking gas. The scope of gas engineering is relatively broad, including large infrastructure projects such as gate stations, compressed gas stations and storage tanks, etc. General civil engineering includes community gas pipeline networks, urban gas pipeline networks, gas pressure regulating stations and in-building gas pipeline installation.

[0003] When installing gas projects, pipe sealing devices are often needed to seal unfinished pipes to prevent dust and debris from entering the pipes, so as to facilitate subsequent connection and expansion of the pipes.

[0004] According to a Chinese patent with publication number CN217951635U, a pipe plugging device for gas engineering installation is disclosed. The pipe plugging device for gas engineering installation can have a higher plugging efficiency, and by plugging the inside of the pipe with a conical plug, the device can be suitable for pipes with different inner diameters, which brings convenience to the staff and improves the practicality of the device.

[0005] In view of the above-mentioned disclosed patent content, a movable conical plug is provided so that the conical plug can be moved into the interior of the pipeline to achieve the purpose of sealing the pipeline, and a sealing ring is provided on the outer wall of the conical plug to improve the sealing after sealing. However, since the sealing ring will be squeezed with the inner wall of the pipeline, the sealing ring will be deformed, and the sealing ring may age after being used for a period of time, thereby weakening its elastic performance. In order to ensure the sealing effect, the sealing ring needs to be replaced, and the replacement process is relatively cumbersome. It may be necessary to remove the device from the pipeline before replacement, thereby affecting the sealing effect of the conical plug. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a pipeline plugging device for gas engineering installation to solve the technical problem of needing to replace the sealing ring at regular intervals to ensure the sealing effect.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipeline plugging device for gas engineering installation, comprising a connecting seat, a limit block and a pipeline body, a sleeve is installed on one side of the connecting seat, and limit grooves are provided at the top and bottom of the sleeve, and a sealing assembly is provided on the outer wall of the sleeve, and the sealing assembly includes a sealing airbag, a push ring, a movable block arranged inside two limit grooves and a fixed ring installed on the outer wall of the sleeve, a movable ring is installed between the two movable blocks, and a compression airbag ring is sleeved between the movable ring and the fixed ring, and a plurality of first springs are installed between the movable ring and the fixed ring, a second spring is provided on one side of the limit block, and a plurality of inflatable hoses are connected between the compression airbag ring and the sealing airbag.

[0008] By adopting the above technical solution, when the movable ring moves, it will squeeze the compressed airbag ring, so that the air inside the compressed airbag ring will enter the sealed airbag through the inflation hose, thereby expanding the sealed airbag.

[0009] Furthermore, a motor is installed on one side of the interior of the connecting seat, a threaded column is connected to the output end of the motor, and a threaded cylinder is sleeved on the outer wall of the threaded column.

[0010] By adopting the above technical solution, when the sealing plug needs to be moved, the staff can start the motor, and the motor can drive the threaded column to rotate, and the threaded cylinder will be driven to move after the threaded column rotates.

[0011] Furthermore, limiting blocks are arranged inside the two limiting grooves, and a push ring is installed between the two limiting blocks.

[0012] By adopting the above technical solution, when the limit block moves, it will drive the push ring to move, so that the push ring can push the movable ring to move.

[0013] Furthermore, the outer wall of the threaded barrel is connected to a limiting block, and the limiting block is slidably connected to the limiting groove.

[0014] By adopting the above technical solution, when the threaded barrel moves, it will drive the limit block to slide inside the limit groove, thereby improving the stability of the threaded barrel when moving and preventing the threaded barrel from rotating.

[0015] Furthermore, a sealing plug is installed at one end of the threaded cylinder, and the sealing airbag is sleeved on the outer wall of the sealing plug.

[0016] By adopting the above technical solution, when the threaded barrel moves, it will drive the sealing plug to move, so that the sealing plug moves into the interior of the pipeline body.

[0017] Furthermore, a guide rod penetrating the movable ring is installed on one side of the fixed ring, and the movable ring is slidably connected to the guide rod.

[0018] By adopting the above technical solution, the guide rod can guide the movable ring so as to improve the stability of the movable ring when moving.

[0019] Furthermore, the sealing component also includes a silicone ring arranged on the inner wall of the pipeline body.

[0020] By adopting the above technical solution, the provision of the silicone ring can prevent the sealing airbag from directly fitting against the inner wall of the pipe body and improve the sealing performance of the sealing airbag.

[0021] Furthermore, the top and bottom of the connecting seat are movably connected to connecting rods, and one end of the two connecting rods is movably connected to an upper clamp and a lower clamp respectively.

[0022] By adopting the above technical solution, when the plugging device needs to be installed, the staff can sleeve the upper clamp and the lower clamp on the outer wall of the pipe body, and then lock it with the locking bolt.

[0023] Furthermore, anti-skid pads are installed on the inner walls of the upper clamp and the lower clamp, and a locking bolt is installed between the upper clamp and the lower clamp.

[0024] By adopting the above technical solution, the locking bolt can lock the upper clamp and the lower clamp, thereby improving the stability of the upper clamp and the lower clamp.

[0025] Furthermore, the sealing assembly also includes an air pipe arranged on the fixing ring, one end of the air pipe extends to the interior of the compression airbag ring, and an air valve is installed on the air pipe.

[0026] By adopting the above technical solution, when the air inside the compressed airbag ring needs to be discharged, the air valve can be opened, and the air inside the compressed airbag ring will be discharged through the air pipe. At the same time, the setting of the air pipe can also fill the external air into the compressed airbag ring.

[0027] In summary, the utility model mainly has the following beneficial effects:

[0028] The utility model is provided with a sealing component. When the threaded tube drives the sealing plug to move into the interior of the pipeline body, the threaded tube will drive the push ring to move, so that the push ring pushes the movable ring to move. When the movable ring moves, it will squeeze the compression airbag ring, so that the air inside the compression airbag ring will enter the sealing airbag through the inflation hose, thereby expanding the sealing airbag. At the same time, the first spring and the second spring will be compressed when the force is applied. After the sealing airbag is expanded, it can fit tightly with the inner wall of the pipeline body, thereby improving the sealing performance of the sealing device. The use of an inflatable sealing airbag for sealing can improve the sealing effect, and avoid the situation where the sealing performance is greatly reduced due to aging of the sealing ring when using elastic parts such as sealing rings, thereby affecting the sealing effect. At the same time, the sealing airbag only needs to be inflated to make it expand and seal, and there is no need to replace it. BRIEF DESCRIPTION OF THE DRAWINGS
