Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline construction technology, specifically relating to a gas pipeline pressurized opening explosion-proof sealing tool. Background Technology

[0002] Live tapping technology for gas pipelines is a key technology in the maintenance of modern urban gas transmission systems. Its core advantage lies in the fact that pipeline tapping can be completed without shutting down the gas supply, thus ensuring the continuity of urban gas supply. With the acceleration of urbanization and the increasing complexity of gas transmission networks, live tapping technology is being used more and more widely in scenarios such as pipeline renovation, maintenance, and new user access. Especially in the field of high-pressure, large-diameter gas pipelines, live tapping technology can significantly reduce gas outage time and reduce the impact on residents' lives and enterprise production, resulting in significant economic and social benefits.

[0003] However, traditional drilling and sealing tools are separate units, requiring multiple steps to disassemble and switch between them during construction. This process is time-consuming and labor-intensive. In emergency repair scenarios, this operation mode can easily delay the golden time for handling the situation and increase the risk of the accident escalating. Therefore, the applicant proposes a gas pipeline pressurized drilling and explosion-proof sealing tool to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a gas pipeline pressurized opening and explosion-proof sealing tool that integrates opening and sealing functions into one unit. It can perform sealing operations after opening without disassembling and switching between the opening and sealing tools, which saves time and effort, avoids delaying the golden treatment time, and reduces the risk of accident escalation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Gas pipeline pressurized tapping and explosion-proof sealing tools include:

[0007] The mounting mechanism and the switching valve mechanism mounted on the top of the mounting mechanism, and the opening sealing mechanism mounted on the top of the switching valve mechanism;

[0008] The installation mechanism includes an upper mounting sleeve and a lower mounting sleeve;

[0009] The switching valve mechanism includes a valve body fixedly installed on the top of the upper mounting sleeve, and a valve core plate is slidably installed inside the valve body;

[0010] The hole sealing mechanism includes a fixed cylinder fixedly installed on the top of the valve body. A rotating rod is installed through the top of the fixed cylinder. The bottom of the rotating rod extends into the fixed cylinder and a drill cylinder is fixedly installed therein. A receiving groove is opened inside the drill cylinder, and an air bladder ball is inserted inside the receiving groove.

[0011] Preferably, the upper mounting sleeve and the lower mounting sleeve are fixed together by a fixing screw, and the valve body is in communication with the upper mounting sleeve and the fixing cylinder.

[0012] Preferably, the valve core plate and the valve body are threaded together by a threaded rod, one end of which extends out of one side of the valve body and is fixedly mounted with a turntable.

[0013] Preferably, the surface of the drill barrel is provided with a vent hole, and an indicator needle aligned with the direction of the storage groove is fixedly installed on one side of the rotating rod.

[0014] Preferably, the inside of the rotating rod is hollow, one side of the rotating rod is connected to an inflation port, and a conduit connects the rotating rod and the airbag bulb.

[0015] Preferably, a connecting block is fixedly installed on the top of the rotating rod, and the connecting block has a square structure.

[0016] Preferably, one side of the fixed cylinder is connected to a connecting pipe, and a vent valve is fixedly installed on the top of the connecting pipe.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model is equipped with a hole-opening and sealing mechanism, which can integrate the hole-opening function and the sealing function into one unit. After drilling a hole in the gas pipeline with a drill barrel, there is no need to move the drilling position. By inflating the airbag ball, the airbag ball can extend out from the storage groove. Through the expansion of the airbag ball, it can easily fit and seal the inner wall of the gas pipeline. There is no need to disassemble and switch the hole-opening tool and the sealing tool. The operation is more time-saving and labor-saving, which can avoid delaying the golden treatment time and reduce the risk of the accident escalating.

[0019] (2) This utility model is equipped with an installation mechanism, which can conveniently wrap the upper and lower installation sleeves around the gas pipeline. This allows the drill to penetrate the gas pipeline vertically, and the bottom of the drill can extend into the lower installation sleeve. The gas in the gas pipeline can be guided to the fixed cylinder through the vent hole on the drill. During the maintenance of the gas pipeline, there is no need to remove the drill, which can save more maintenance time and improve the usage effect. Attached Figure Description

[0030] Example 1:

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the gas pipeline pressurized tapping and explosion-proof sealing tool includes:

[0032] The mounting mechanism 3 and the switching valve mechanism 2 mounted on the top of the mounting mechanism 3, and the opening sealing mechanism 1 mounted on the top of the switching valve mechanism 2;

[0033] The mounting mechanism 3 includes an upper mounting sleeve 31 and a lower mounting sleeve 32;

[0034] The switching valve mechanism 2 includes a valve body 21 fixedly installed on the top of the upper mounting sleeve 31, and a valve core plate 22 is slidably installed inside the valve body 21;

[0035] The hole sealing mechanism 1 includes a fixed cylinder 11 fixedly installed on the top of the valve body 21. A rotating rod 14 is installed through the top of the fixed cylinder 11. The bottom of the rotating rod 14 extends into the fixed cylinder 11 and a drill cylinder 18 is fixedly installed therein. A receiving groove 110 is opened inside the drill cylinder 18, and an air bladder ball 111 is inserted inside the receiving groove 110.

[0036] As can be seen from the above, when in use, the upper mounting sleeve 31 is attached to the top of the gas pipeline and the lower mounting sleeve 32 is attached to the bottom of the gas pipeline. By fixing the upper mounting sleeve 31 and the lower mounting sleeve 32, it can be easily clamped on the surface of the gas pipeline. By moving the valve core plate 22 to one side, the valve body 21 can be connected with the fixed cylinder 11 and the upper mounting sleeve 31. By rotating the rotating rod 14, the drill barrel 18 can be rotated synchronously. The rotating rod 14 can move up and down along the fixed cylinder 11, which can drive the drill barrel 18 to move downward, so that the drill barrel 18 can extend into the upper mounting sleeve 31, which is convenient for drilling the gas pipeline. By continuing to move downward and extending into the lower mounting sleeve 32, the gas pipeline can be easily penetrated from top to bottom.

[0037] By guiding airflow through the internal cavity of the rotating rod 14 into the airbag bulb 111, the airbag bulb 111 can expand, extending into the receiving groove 110. As the airbag bulb 111 continues to expand, it can easily seal the inner wall of the gas pipeline without disassembling and switching the drilling and sealing tools. This saves time and effort, avoids delaying the golden treatment time, and reduces the risk of the accident escalating. After sealing the gas pipeline, the gas in the pipeline can enter the fixed cylinder 11. By connecting a temporary delivery pipeline between the fixed cylinders 11, the gas can be easily transported around the damaged gas pipeline without the need to shut off the gas supply.

[0038] Depend on Figure 4 It can be seen that the upper mounting sleeve 31 and the lower mounting sleeve 32 are fixed by the fixing screw 33, and the valve body 21 is connected to the upper mounting sleeve 31 and the fixing cylinder 11.

[0039] As can be seen from the above, the upper mounting sleeve 31 and the lower mounting sleeve 32 can be easily closed and locked by the fixing screw 33, so that the upper mounting sleeve 31 and the lower mounting sleeve 32 can tightly clamp the gas pipeline and are not easy to fall off.

[0040] For details, please refer to Figure 5 As shown, the valve core plate 22 and the valve body 21 are threaded together by a threaded rod 23. One end of the threaded rod 23 extends out of one side of the valve body 21 and is fixedly mounted with a turntable 24.

[0041] As can be seen from the above, by using the turntable 24, the threaded rod 23 can be easily rotated. The threaded engagement between the threaded rod 23 and the valve core plate 22 allows the rotation of the threaded rod 23 to easily drive the valve core plate 22 to move left and right, which can conveniently control the opening and closing operation of the valve body 21.

[0042] For details, please refer to Figure 6 As shown, the surface of the drill barrel 18 is provided with a vent hole 19, and an indicator needle 15 is fixedly installed on one side of the rotating rod 14, which is aligned with the direction of the storage groove 110.

[0043] As can be seen from the above, by sealing the gas pipeline, the gas can enter the drill barrel 18 through the vent hole 19, and the gas can be normally introduced into the fixed cylinder 11. During the maintenance of the gas pipeline, there is no need to remove the drill barrel 18. The direction indicated by the indicator needle 15 can make it easy for personnel to know the orientation of the collection groove 110 in the gas pipeline, and can easily control the rotation of the drill barrel 18 to make the collection groove 110 face the correct direction for sealing.

[0044] Example 2:

[0045] refer to Figure 6As shown, the inside of the rotating rod 14 is hollow, and an inflation port 17 is connected to one side of the rotating rod 14. A conduit 112 is connected between the rotating rod 14 and the airbag bulb 111.

[0046] As can be seen from the above, after drilling is completed, the rotating rod 14 is stopped from rotating. The air inlet 17 can be easily connected to the air pump equipment, and the airflow can be easily introduced into the rotating rod 14. The airflow can be delivered into the airbag ball 111 through the conduit 112, so that the airbag ball 111 can be expanded to seal the gas pipeline.

[0047] refer to Figure 6 As shown, a connecting block 16 is fixedly installed on the top of the rotating rod 14. The connecting block 16 has a square structure.

[0048] As can be seen from the above, the connecting block 16 can be easily connected to the drill bit of the electric drill, and the electric drill can be used to drive the rotating rod 14 to rotate, which can facilitate the drilling barrel 18 to open holes in the gas pipeline.

[0049] refer to Figure 1 As shown, a connecting pipe 12 is connected to one side of the fixed cylinder 11, and a vent valve 13 is fixedly installed on the top of the connecting pipe 12.

[0050] As can be seen from the above, the temporary delivery pipeline can be easily connected through the connecting pipe 12 to form a bypass delivery pipe, which can easily bypass the damaged location of the gas pipeline and facilitate the continuous delivery of gas through the bypass.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
