Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline maintenance technology, specifically a rapid leak-sealing device for chemical hazardous materials pipelines. Background Technology

[0002] Chemical pipelines play a vital role in industrial production, transporting various liquids, gases, and chemicals. However, during prolonged use, these pipelines may rupture due to external forces, collisions, or corrosion, necessitating leak sealing.

[0003] A search revealed that the authorization announcement number CN214119357U proposes a leak-sealing device for chemical pipelines. This device is fitted and fixed to the outside of the pipeline leak point through the cooperation of a movable opening, a fixed spiral rod, a fixed perforation, a fixed slot, and a fixed rotating pile. Then, the leak point is sealed through the cooperation of a pressurized pipe, a movable piston, a movable slot, a control rod, a pressurized pad, and a sealing reinforcement plate.

[0004] However, due to long-term exposure to wind and sun and corrosion, chemical pipelines have uneven corrosion bumps and depressions on their exterior. As mentioned above, the overall encircling leak-sealing method often results in leakage even after the leak point is plugged because of the unevenness of the pipeline, and the leak-sealing effect is not good.

[0014] (III) Beneficial Effects

[0015] This utility model provides a rapid leak-sealing device for chemical hazardous materials pipelines. It has the following beneficial effects:

[0016] 1. This rapid leak-sealing device for chemical hazardous material pipelines uses a base frame and a fixed frame to locate the leak. Then, the leak-sealing tape and sealing sleeve are used to accurately locate the leak. The sealing sleeve is then firmly pressed against the leak by tightening bolts. This effectively avoids leak-sealing failure caused by unevenness of the pipeline, greatly improves the leak-sealing effect, and makes the leak point less prone to leakage.

[0020] This utility model provides a rapid leak-sealing device for chemical hazardous materials pipelines, such as... Figure 1-2 As shown, the device used to plug the leak in pipe 1 includes a semi-circular base frame 2, two semi-circular fixing brackets 3, and a leak-sealing tape 5. The length of the base frame 2 is greater than the length of the two fixing brackets 3.

[0021] Both ends of the two fixing brackets 3 are provided with corresponding screw holes between them and the base frame 2. The two fixing brackets 3 and the base frame 2 can be wrapped around the pipe 1 by fastening bolts 4. During installation, the two fixing brackets 3 are distributed on both sides of the leak, and the sealing strip 5 is placed between the two fixing brackets 3. The function of the two fixing brackets 3 and the base frame 2 is to position the sealing strip 5 between the leak and the leak.

[0022] like Figure 1 As shown, support seats 8 are provided at the middle of both ends of the fixing frame 3. The two ends of the sealing strip 5 are telescopically connected to the support seats 8, and a sealing sleeve 6 is fitted on the sealing strip 5. A rubber pad is provided on the side of the sealing sleeve 6 that contacts the pipe 1.

[0023] The top of the sealing sleeve 6 is vertically threaded with a clamping bolt 7 corresponding to the sealing strip 5. When sealing, slide the sealing sleeve 6 to the leak position, and then tighten the clamping bolt 7. By squeezing the sealing strip 5, the rubber gasket at the bottom of the sealing sleeve 6 is firmly pressed against the leak, achieving the best sealing effect.

[0024] like Figure 1-2 As shown, the support base 8 has a slot 9 through which the sealing strip 5 passes. Both ends of the sealing strip 5 are toothed strips 10. A sliding cavity 11 is laterally formed inside the support base 8. A toothed plate 12 corresponding to the toothed strip 10 is slidably fitted inside the sliding cavity 11. An adjusting screw 15 is threaded laterally onto the support base 8. The end of the adjusting screw 15 corresponds to the toothed plate 12, but is not directly connected to the toothed plate 12. The adjusting screw 15 is used to push the toothed plate 12 to move. The toothed plate 12 is connected to the inner end of the sliding cavity 11 by a spring 13. Under normal conditions, the toothed plate 12 pushes against the toothed strip 10 under the action of the spring 13. A connecting rod 14 is laterally arranged on the side of the toothed plate 12 away from the teeth. The outer end of the connecting rod 14 passes through the support base 8 and extends to the outside. The connecting rod 14 can be pulled to control the toothed plate 12.

[0025] The corresponding sides of the rack belt 10 and the toothed plate 12 are both triangular teeth.

[0026] Working Principle: Step 1: Locate the leak and fix the two fixing brackets 3 and the base frame 2 to the pipe 1 with the leak as the center. Step 2: Insert both ends of the sealing tape 5 into the slots 9, then slide the sealing sleeve 6 to the leak location and tighten the clamping bolt 7 to firmly press it against the leak. Step 3: Pull the connecting rod 14 outward, then pull the rack belts 10 at both ends of the sealing tape 5 downward to fully tighten it. After that, release the connecting rod 14 so that the toothed plate 12 locks the rack belt 10. Step 4: Rotate the adjusting screw 15 to firmly press the toothed plate 12 against the rack belt 10, preventing the toothed plate 12 from loosening.
