Description

Technical Field

[0001] This utility model relates to the field of pipeline leak sealing technology, specifically a pressurized fastening leak sealing method. Background Technology

[0002] When a pressurized pipeline leaks unexpectedly due to corrosion, perforation, human damage, or natural disasters during the transportation of media, the leaking medium can be plugged without reducing the pressure by transferring the leaked medium to another container or stopping the transport. This can be achieved using live leak sealing technology.

[0003] As disclosed in the authorization announcement number CN202791137U, a flow-guiding type pressurized leak-sealing device consists of a sealing element, a clamping element, a flow-guiding ball valve short connector, a flow-guiding ball valve, a flow-guiding pipe, a flow-guiding hose, a nut, an Ω-shaped pressure plate, and a U-shaped double-ended bolt. The beneficial effect of this utility model after adopting the above technical solution is that it can perform pressurized leak sealing for leaks with large leakage volume, high leakage pressure, and hazardous leaking media.

[0004] Although the aforementioned patent can perform pressurized sealing for leaks with large leakage volume, high leakage pressure, and hazardous leakage media, the two nuts need to be tightened symmetrically and in stages (such as pre-tightening and then final tightening), which is time-consuming and requires a high level of skill from the personnel. If the tightening torque of the two nuts is uneven, it may cause the Ω-shaped pressure plate or seal to be under unbalanced force, which may reduce the sealing performance. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution:

[0026] A pressurized fastening and leak-sealing device includes a U-bolt 1, a clamping plate 2 on the left side of the U-bolt 1, an arc-shaped groove 3 in the middle of the right side of the clamping plate 2, a drainage conduit 4 fixedly connected to the middle of the right side of the U-bolt 1, a sealing mechanism on the side of the drainage conduit 4 near the clamping plate 2, the sealing mechanism including an arc-shaped sealing element 6, the left end of the drainage conduit 4 passing through the U-bolt 1 and fixedly connected to the arc-shaped sealing element 6, the middle of the arc-shaped sealing element 6 having a guide groove 8 communicating with the drainage conduit 4, drive sleeves 5 symmetrically arranged inside both ends of the clamping plate 2, and a synchronous rotation mechanism between the clamping plate 2 and the drive sleeves 5, the synchronous rotation mechanism including a double-groove synchronous... The pulley 12 is movably installed in the middle of the inner side of the left end of the clamping plate 2. The single groove synchronous pulley 13 is fixedly connected to the outer wall of the left end of the drive sleeve 5. The double groove synchronous pulley 12 meshes with the single groove synchronous pulley 13 on both sides through two synchronous belt bodies. The synchronous rotation mechanism also includes a rotating rod 14. The rotating rod 14 is movably installed in the middle of the left side of the clamping plate 2 through a bearing. The right end of the rotating rod 14 is coaxially connected to the double groove synchronous pulley 12. The left end of the rotating rod 14 is fixedly connected to a hexagonal bolt head 15. The guide ring 16 is fixedly installed on the outer side of the right side of the drive sleeve 5. The inner sides of the clamping plate 2 are provided with annular guide grooves 7 that are slidably connected to the guide ring 16.

[0027] In this embodiment, the synchronous rotation mechanism enables the synchronous rotation of the two drive sleeves 5, ensuring that the force on both sides of the clamping plate 2 is uniform. This completely solves the problem that the two nuts need to be tightened in stages and the torque is uneven in the traditional method, and significantly improves the sealing reliability and operating efficiency.

[0028] Furthermore, the transmission method of using the rotating rod 14 to drive the double-groove synchronous pulley 12 can realize the synchronous feeding of the two drive sleeves 5 through a single operating point. The operation is simple and quick, greatly reducing the technical requirements for operators, and is especially suitable for emergency repair situations.

[0029] like Figure 1 and Figure 4 As shown, a directional adjustment mechanism is provided on the right side of the drainage conduit 4. The directional adjustment mechanism includes a rotary joint 9. The rotary joint 9 is fixedly installed at the right end of the drainage conduit 4. A corrugated rubber tube 10 is fixedly connected to the movable end of the rotary joint 9. A rigid joint 11 is fixedly connected to the end of the corrugated rubber tube 10 away from the rotary joint 9.

[0030] In this embodiment, the combined use of the rotary joint 9 and the corrugated rubber tube 10 solves the problem of media export in confined spaces and greatly expands the applicability of the device.

[0031] Working principle: When a leak occurs in the pipe body 17, the U-bolt 1 is bridging the leak point, aligning the arc-shaped seal 6 with the leak point. Simultaneously, the drive sleeves 5 at both ends of the clamp plate 2 are engaged with the threaded heads of the U-bolt 1. By rotating the hexagonal bolt head 15, the rotating rod 14 is driven to rotate. The rotating rod 14 drives the double-groove synchronous pulley 12 to rotate. The double-groove synchronous pulley 12 drives the single-groove synchronous pulleys 13 on both sides to rotate synchronously through the synchronous belt body. This drives the drive sleeves 5 on both sides to screw in along the threads of the U-bolt 1, pushing the clamp plate 2 to move to the other side of the pipe body 17, so that the arc-shaped groove 3 of the clamp plate 2 abuts against the outer wall of the pipe body 17. At the same time, the arc-shaped seal 6 is pressed to the leak point to achieve initial sealing. At this time, the leaking medium enters the drainage pipe 4 through the guide groove 8 of the arc-shaped seal 6. The drainage pipe 4 guides the leaking medium to the rotary joint 9. The use of the rotary joint 9 and the corrugated rubber hose 10 is particularly suitable for the working conditions where the pipe body 17 is installed close to the wall and the operating space between it and the wall is limited. Through the universal adjustment function of the rotary joint 9, the corrugated rubber hose 10 can be flexibly adjusted in the limited space to adjust the outlet direction. Then, the leaking medium is safely discharged to the recovery device through the rigid joint 11, and finally the rapid leak sealing and medium drainage under pressure is achieved.

[0032] It should be noted that the synchronous rotation mechanism adopts a cross-drive arrangement, wherein one end of the first synchronous belt body is engaged in the transmission groove on the left side of the double-groove synchronous pulley 12, and the other end is connected to the single-groove synchronous pulley 13 on the left side; the second synchronous belt body is engaged in the transmission groove on the right side of the double-groove synchronous pulley 12, and the other end is connected to the single-groove synchronous pulley 13 on the right side. The symmetrical arrangement ensures that when the rotating rod 14 drives the double-groove synchronous pulley 12 to rotate, the two synchronous belt bodies drive the single-groove synchronous pulleys 13 on both sides in a completely synchronous manner, so that the two drive sleeves 5 obtain completely consistent rotational speed and torque.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
