A pipeline repair section

Abstract

The invention discloses a pipeline rush-repair joint, which comprises an outer shell and a sealing ring, wherein the sealing ring is arranged between the outer shell and a pipeline to be repaired, the internal diameter of the sealing ring is larger than or equal to the external diameter of the pipeline to be repaired; according to the pipeline rush-repair joint, the internal diameters and the external diameters of the outer shell and the sealing ring are increased on the basis of the original structure, the arc lengths of the outer shell and the sealing ring are unchanged, so that the internal diameter of the sealing ring is consistent with the external diameter of the pipeline to be repaired, the sealing ring is prevented from overturning and deforming because the opening end is large in friction force in the installing process, so that the sealing ring is better in compression uniformity, and therefore the sealing property of the sealing ring is improved; and in addition, because the sealing ring is uniform in stress due to uniform compression, the sealing ring is not easy to damage, and therefore the sealing ring is longer in service life.

Description

technical field [0001] The invention relates to the technical field of pipeline emergency repair, in particular to a pipeline emergency repair joint. Background technique [0002] With the increasing development of urban construction, various pipelines are more and more used in various aspects such as water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, and water conservancy. [0003] During the use of the pipeline, due to factors such as building or road construction, the pipeline may leak or be damaged, and emergency repairs are required. Usually, the pipeline emergency repair section is used to repair the damaged part of the pipeline; the pipeline emergency repair section uses its shell and shell The sealing ring in the body wraps the damaged part of the pipeline, and then clamps it to quickly achieve the purpose of plugging. [0004] Please refer to figure 1 , figure 1 It is a schematic structur...

AI Technical Summary

Problems solved by technology

However, the inner diameter of the sealing ring is smaller than the outer diameter of the pipeline to be repaired, and the inner diameter of the ring formed after the connection of the two housings is equal to the inner diameter of the sealing ring in a normal state. When the pipeline repair section is installed, the sealing ring is sleeved on the pipeline Finally, the sealing ring expands, and its outer diameter is larger than the outer diameter of the normal state, which is larger than the inner diameter of the ring formed after the shell is connected. Circular friction and turning inward, so that the sealing ring cannot be uniformly compressed, the sealing effect is poor, and in severe cases, the sealing ring will be damaged, shortening the service life of the pipeline emergency repair joint
