Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline sealing, in particular to a rapid sealing device for repairing petroleum pipelines. Background Art

[0002] The oil pipeline is composed of an oil pipe and its accessories, and is equipped with corresponding oil pump units according to the needs of the process flow. It is designed and installed into a complete pipeline system to complete the tasks of oil loading and unloading and transfer. When a leak occurs in the oil pipeline, it needs to be sealed and repaired. After searching, the patent with application number 201921854773.0 discloses an oil pipeline leakage sealing repair mold, which relates to the field of pipeline sealing technology. The utility model includes a mold tube that is sleeved on the outside of the pipeline, and a temporary sealing mechanism is provided on the mold tube. The temporary sealing mechanism includes a fastening screw threadedly connected to the mold tube, and the bottom of the fastening screw is threadedly connected to an arc-shaped sealing plate. The arc-shaped sealing plate is used to fit the leaking part of the pipeline. The top of the arc-shaped sealing plate is connected to a sleeve located between the arc-shaped sealing plate and the mold tube, and the fastening screw can move up and down in the sleeve.

[0003] However, during actual use, the applicant found that the arc-shaped sealing plate was fixed by a sealant and the damaged part of the oil pipeline was sealed by the arc-shaped sealing plate. Due to the insufficient structural strength of the sealant, the repair seal of the damaged part of the oil pipeline was not stable enough and was easily broken, thereby losing the sealing effect of the damaged part of the oil pipeline. In view of this, we propose a rapid sealing device for repairing oil pipelines. Utility Model Content

One end of the positioning stud 14 is threadedly matched with the lock nut 16. The inner wall of the first semicircular sealing hoop 11 and the second semicircular sealing hoop 12 is fixed with a positioning through hole 15. A sealing gasket 18 is fixedly provided on the side wall, and the sealing gasket 18 abuts against the outer wall of the oil pipeline 3. Except for the sealing gasket 18, the pipeline seal 1 is made of metal material, has high structural strength, and can effectively repair and seal the damaged part of the oil pipeline 3. When repairing the damaged part of the oil pipeline 3, the middle part of the inner side of the first semicircular sealing hoop 11 can be aligned with the damaged position, and the first semicircular sealing hoop 11 can be put on the outside of the oil pipeline 3 so that the sealing gasket 18 abuts against the outer wall of the oil pipeline 3 to seal the damaged part. Then, the second semicircular sealing hoop 12 is put on the outside of the oil pipeline 3, and after the positioning stud 14 passes through the positioning through hole 15, the anti-loosening nut 16 is screwed onto the positioning stud 14 to quickly connect the first semicircular sealing hoop 11 and the second semicircular sealing hoop 12.

[0022] The outer walls of the first semicircular sealing hoop 11 and the second semicircular sealing hoop 12 are fixedly provided with a tight support 17, the inner wall of the support arm on one side of the U-shaped bracket 2 is fixedly provided with a limiting protrusion 21, and the support arm on the other side of the U-shaped bracket 2 is connected with an abutment block 5 through a screw 6.
