Description

Technical Field

[0001] This utility model relates to the field of gas engineering technology, and in particular to an outdoor gas pipeline venting device. Background Technology

[0002] When repairing or replacing outdoor gas pipelines, it is necessary to release the gas inside the pipeline. This is usually done by drilling. Ordinary drill bits are typically used for drilling. Once the drilling is completed, the gas release is uncontrollable. In the early stages, a large amount of gas is released directly. However, because the space in the gas pipeline well or the excavated pit is relatively small, the released gas cannot circulate, which will cause the gas concentration in the space to increase, making it very easy to cause a safety accident. Utility Model Content

[0003] One objective of this application is to provide an outdoor gas pipeline venting device that can control the discharge of gas after drilling.

[0004] The technical solution adopted in this application is as follows: an outdoor gas pipeline venting device, including a sealing sleeve, a drilling mechanism, and a clamp for fixing to the gas pipeline. The clamp is provided with a connector, and one end of the sealing sleeve is connected to the connector. The drilling mechanism includes a drill rod and a hole opener or drill bit for making holes. The drill rod passes through the sealing sleeve, and one end of the drill rod is connected to the hole opener or drill bit. A sealing element is provided between the sealing sleeve and the drill rod, and a venting valve is provided on the sealing sleeve.

[0005] Compared with existing technologies, the advantages of this application are as follows: the clamp is fixed to the gas pipeline, and the hole opener passes through the connector to make the hole, which can make the hole opening position precise; the end of the drill rod far from the hole opener extends out of the sealing sleeve, which is convenient to drive with an electric drill or rotate manually, thereby driving the hole opener to rotate and make the hole; the vent valve is connected to the inside of the sealing sleeve, and the opening of the vent valve can control the gas in the sealing sleeve to be discharged outward; the sealing element is used to improve the sealing performance between the sealing sleeve and the drill rod and prevent gas from leaking between the two; when the clamp and the gas pipeline are assembled, the sealing sleeve and the clamp form an integral seal. At this time, after the hole is made in the gas pipeline by the hole opener, the gas in the gas pipeline will also be confined in the sealing sleeve and will not be discharged directly. The workers can control the amount of gas discharged by the vent valve to prevent the gas concentration in the gas pipeline well or the excavated tunnel space from exceeding the standard, thereby improving safety.

[0006] In some embodiments of this application, an extension tube is provided between the connector and the sealing sleeve. One end of the extension tube is connected to the connector, and the other end is connected to the sealing sleeve. The design of the extension tube increases the distance between the sealing sleeve and the clamp, making the installation of the sealing sleeve more convenient, raising the height of the vent valve, facilitating discharge, and making the operation of the vent valve easier.

[0007] Furthermore, a ball valve is provided between the extension tube and the sealing sleeve. One end of the ball valve is connected to the extension tube, and the other end is connected to the sealing sleeve. The ball valve design allows for control of venting even if the vent valve fails, improving safety. Additionally, after drilling is completed, the sealing sleeve and drilling mechanism can be removed, and other devices can be connected via the ball valve, enhancing functionality.

[0008] In some embodiments of this application, the hole opener or drill bit is detachably connected to the drill rod, which facilitates the replacement of hole openers or drill bits of different specifications, thereby achieving hole openings of different specifications, thus having a wider range of applications. Furthermore, since hole openers or drill bits are prone to wear after long-term use, detachable design facilitates disassembly and maintenance, making it more practical.

[0009] In some embodiments of this application, the end of the drill rod away from the clamp is provided with a fixed plane. The fixed plane facilitates clamping, ensures reliable connection with the electric drill and prevents slippage during rotation, or ensures reliable connection with tools such as wrenches, facilitating manual rotation.

[0010] In some embodiments of this application, the sealing sleeve includes a cylindrical body and a rear cover. One end of the cylindrical body is connected to a connector, and the other end of the cylindrical body is connected to the rear cover. A drill rod passes through the rear cover, and a vent valve is located on the cylindrical body. The drill rod passing through the rear cover reduces the friction area between the drill rod and the sealing sleeve. Furthermore, the rear cover is removable, facilitating observation of the internal condition of the cylindrical body. If necessary, the rear cover can be removed to retrieve the drill rod for replacement of the hole opener.

[0011] In some embodiments of this application, the seal is an O-ring.

[0012] In some embodiments of this application, the seal is a mechanical seal.

[0013] In some embodiments of this application, the maximum diameter of the hole opener or drill bit is smaller than the inner diameter of the sealing sleeve. The hole opener or drill bit can be inserted into the cylinder to avoid external collisions. When disassembled for transportation, the hole opener or drill bit exposed outside poses a risk of scratching workers. The risk is lower when it is inserted into the cylinder for transportation. When the cylinder and the ball valve are installed, there is no interference from the hole opener, and the connection between the two is more convenient and safer.

[0014] In some embodiments of this application, the vent valve is equipped with an exhaust pipe, which is detachably connected to the vent valve. The exhaust pipe is designed to vent the gas to other locations, improving safety.

[0015] Furthermore, the vent valve is detachably connected to the exhaust pipe via a quick-connect coupling. The quick-connect coupling allows for rapid insertion and removal of the exhaust pipe, facilitating its installation and removal, and also allows for easy folding and storage of the exhaust pipe separately.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Example 1:

[0020] This embodiment provides an outdoor gas pipeline venting device, such as... Figure 1 As shown, the system includes a sealing sleeve 1, a drilling mechanism 2, and a clamp 3 for fixing to the gas pipeline. The clamp 3 has a connector 4, and one end of the sealing sleeve 1 is connected to the connector 4. The drilling mechanism 2 includes a drill rod 5 and a hole opener 6 or drill bit for drilling. The drill rod 5 passes through the sealing sleeve 1, and one end of the drill rod 5 is connected to the hole opener 6 or drill bit. A sealing element 7 is provided between the sealing sleeve 1 and the drill rod 5, and a vent valve 8 is provided on the sealing sleeve 1. In this embodiment, the hole opener 6 is used; the vent valve 8 communicates with the interior of the sealing sleeve 1; and the drilling mechanism 2 is arranged perpendicular to the gas pipeline.

[0021] The clamp 3 is fixed to the gas pipeline, and the hole opener 6 passes through the connector 4 to make a hole, which can make the hole position precise. The drill rod 5 extends beyond the sealing sleeve 1 at one end away from the hole opener 6, which can be driven by an electric drill or manually rotated, thereby driving the hole opener 6 to rotate and make a hole. The vent valve 8 is connected to the inside of the sealing sleeve 1. Opening the vent valve 8 can control the gas in the sealing sleeve 1 to be discharged outward. The seal 7 is used to improve the sealing performance between the sealing sleeve 1 and the drill rod 5 to prevent gas from leaking between the two. When the clamp 3 is assembled with the gas pipeline, the sealing sleeve 1 and the clamp 3 form an integral seal. At this time, after making a hole in the gas pipeline through the hole opener 6, the gas in the gas pipeline will also be restricted in the sealing sleeve 1 and will not be discharged directly. The workers can control the amount of gas discharged through the vent valve 8 to prevent the gas concentration in the gas pipeline well or the excavated tunnel space from exceeding the standard and improve safety.

[0022] For ease of operation, an extension tube 9 is provided between the connector 4 and the sealing sleeve 1. One end of the extension tube 9 is connected to the connector 4, and the other end of the extension tube 9 is connected to the sealing sleeve 1. The design of the extension tube 9 increases the distance between the sealing sleeve 1 and the clamp 3, making the installation of the sealing sleeve 1 more convenient, raising the height of the vent valve 8, facilitating discharge, and making the operation of the vent valve 8 easier.

[0023] To enhance safety, a ball valve 10 is provided between the extension tube 9 and the sealing sleeve 1. One end of the ball valve 10 is connected to the extension tube 9, and the other end is connected to the sealing sleeve 1. The ball valve 10 is designed to control venting even if the vent valve 8 fails, thus improving safety. Furthermore, after drilling is completed, the sealing sleeve 1 and drilling mechanism 2 can be removed, and other devices can be connected via the ball valve 10.

[0024] To facilitate drilling holes of different sizes, the hole opener 6 or drill bit is detachably connected to the drill rod 5, making it easy to replace the hole opener 6 or drill bit of different sizes, thereby achieving drilling of different sizes and expanding the range of applications. In addition, the hole opener 6 or drill bit is prone to wear after long-term use, and the detachable design makes it easy to disassemble, install, maintain and replace, making it more practical.

[0025] To facilitate rotation of the drill rod 5, a fixed plane 11 is provided at the end of the drill rod 5 away from the clamp 3. The fixed plane 11 can be easily clamped, has a reliable connection with the electric drill, prevents slippage during rotation, or has a reliable connection with tools such as wrenches, facilitating manual rotation.

[0026] To ensure reliable sealing of the sleeve 1, the sleeve includes a cylindrical body 12 and a rear cover 13. One end of the cylindrical body 12 is connected to the connector 4, and the other end is connected to the rear cover 13. The drill rod 5 passes through the rear cover 13, and a vent valve 8 is installed on the cylindrical body 12. Both ends of the cylindrical body 12 are threaded to the rear cover 13 and the ball valve 10 respectively, facilitating easy assembly and disassembly. Sealing rings are provided between both ends of the cylindrical body 12 and the rear cover 13 and the ball valve 10. The vent valve 8 communicates with the inside of the cylindrical body 12. The drill rod 5 passing through the rear cover 13 reduces the friction area between the drill rod 5 and the sealing sleeve 1. Furthermore, the rear cover 13 is removable, allowing for easy observation of the inside of the cylindrical body 12. If necessary, the rear cover 13 can be removed to remove the drill rod 5 for replacement of the hole opener 6.

[0027] To ensure reliable sealing, the sealing element 7 uses an O-ring, which has low procurement cost. The O-ring is located between the rear cover 13 and the drill rod 5, and two O-rings are provided. Of course, the sealing element 7 can also be located between the cylinder 12 and the drill rod 5, with the sealing element 7 higher than the vent valve 8; the sealing element 7 can also be a mechanical seal.

[0028] To improve the protection of the hole opener 6 or drill bit, the maximum diameter of the hole opener 6 or drill bit is smaller than the inner diameter of the cylinder 12. The hole opener 6 or drill bit can be inserted into the cylinder 12 to avoid external collisions. When disassembled for transportation, the hole opener 6 or drill bit exposed outside poses a risk of scratching workers. The risk is lower when it is transported inside the cylinder 12. When the cylinder 12 and the ball valve 10 are installed, there is no interference from the hole opener 6, and the connection between the two is more convenient and safer.

[0029] To facilitate venting, the vent valve 8 is equipped with an vent pipe 14, which is detachably connected to the vent valve 8. In this embodiment, the vent pipe 14 is a flexible hose. The design of the vent pipe 14 allows the gas to be vented to other locations, improving safety.

[0030] To facilitate the installation and removal of the exhaust pipe 14, the vent valve 8 is detachably connected to the exhaust pipe 14 via a quick connector 15. In this embodiment, the quick connector 15 is a flexible hose quick connector. The quick connector 15 enables quick insertion and removal of the exhaust pipe 14, facilitating its installation and removal, and also allows for easy folding and storage of the exhaust pipe 14.
