Embodiment 1

[0017] Such as figure 1 As shown, a kind of air bag for maintenance of oil pipelines comprises an air bag 1, an air nozzle 2 arranged on the air bag 1, a tee 3 connected with the air nozzle 2, the third end of the tee 3 is connected with the air nozzle 2, and also includes A hose A4 connected to the first end of the tee 3, a hose B5 connected to the second end of the tee 3, a ball valve 6 connected to the end of the hose A4, and an air pump 7 connected to the end of the hose B5 And the pressure sensor 8 electrically connected with the air pump 7, the pressure sensor 8 is arranged on the hose B5.

[0018] In this embodiment, when the damaged oil pipeline needs to be repaired, the air bag 1 only needs to be placed on the two ends of the oil pipeline, and then the air bag 1 is inflated by the air pump 7, as long as the oil between the two air bags 1 is pumped The oil pipeline can be repaired as soon as possible, the operation procedure is simple, time-saving and labor-saving, an...

Embodiment 2

[0021] On the basis of Embodiment 1, this embodiment further includes pull rods 9 disposed on the left and right ends of the airbag 1 and pull rings 10 disposed on the pull rods 9 .

[0022] The pull ring 10 in this embodiment can pull the air bag 1 out of the oil pipeline after the emergency repair of the oil pipeline is completed.

Embodiment 3

[0024] In this embodiment, on the basis of embodiment 1 or embodiment 2, the airbag 1 is composed of an inner surface layer 11, an intermediate layer 12 and an outer layer 13, the inner surface layer 11 and the outer layer 13 are made of rubber materials, and the intermediate layer 12 is Nylon, cotton or cord.

[0025] In this embodiment, the inner surface layer 11 and the outer surface layer 13 of the airbag 1 are made of rubber material, which has high wear resistance and corrosion resistance. The middle layer 12 is made of nylon or cotton thread or cord, which increases the rigidity of the entire capsule body 1, and can avoid excessive deformation of the capsule body 1 in the uneven pipeline, which makes it difficult to pull, and also avoids being scratched by pipeline protrusions during use Inner skin 11 and air leakage.

Abstract

The invention discloses an air bag for overhauling a petroleum pipeline. The air bag comprises an air bag body, an air cock arranged on the air bag body and a tee joint connected with the air cock. The air bag further comprises a hose A connected with the position A of the tee joint, a hose B connected with the position B of the tee joint, a ball valve connected to the tail end of the hose A, an air pump connected to the tail end of the hose B, and a pressure sensor electrically connected with the air pump. The pressure sensor is arranged on a pipeline of the hose B. According to the air bag for overhauling the petroleum pipeline, due to the arrangement of the air bag body, petroleum at the two ends of the inside of the air bag body only needs to be fully pumped during first-aid repair, the operating procedure is simple, time and labor are saved, and working efficiency is greatly improved.

Description

technical field [0001] The invention relates to an air bag, in particular to an air bag for oil pipeline maintenance. Background technique [0002] In the oil industry, it is necessary to lay long pipelines for oil transportation, but because most of the oil pipelines are laid in relatively harsh environments, there are often leakages, ruptures, etc., requiring staff to repair and weld the pipelines in time , but in the repair process, the oil in the entire oil pipeline needs to be pumped clean, the workload is heavy and the operation is troublesome. Contents of the invention [0003] In order to solve the defects of heavy workload and cumbersome operation for repairing oil pipelines, the present invention provides an air bag for oil pipeline maintenance. [0004] Technical scheme of the present invention is as follows: [0005] An air bag for oil pipeline maintenance, including an air bag, an air nozzle arranged on the air bag, a tee connected to the air nozzle, the thi...
