Embodiment 1

[0020] Such as figure 1 , figure 2 As shown, the blockage device for oil pipelines with tension bars includes an air bag 1, an air nozzle 2 arranged on the air bag 1, a hose 3 connected to the air nozzle 2, and an air pump connected to the end of the hose 3 4 and the pressure gauge 5 installed on the flexible pipe 3 also includes shaped tie bars 6 uniformly arranged on the outer surface of the airbag 1 . The shaped tie bar 6 is a cuboid structure.

[0021] 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 4, as long as the oil between the two air bags 1 The oil pipeline can be repaired as soon as the exhaust is exhausted. The operation procedure is simple, time-saving and labor-saving, and the work efficiency is greatly improved. The pressure gauge 5 can monitor the air pressure value in the airbag 1 in real time, and the staff...

Embodiment 2

[0023] On the basis of Embodiment 1, this embodiment further includes pull rods 7 arranged on the left and right ends of the airbag 1 and pull rings 8 arranged on the pull rods 7 .

[0024] The pull ring 8 in this embodiment can pull the airbag 1 out of the oil pipeline after the emergency repair of the oil pipeline is completed.

Embodiment 3

[0026] In this embodiment, on the basis of Embodiment 1 or Embodiment 2, the airbag 1 is composed of an inner skin 9, an intermediate layer 10 and an outer skin 11, the inner skin 9 and the outer skin 11 are made of rubber materials, and the middle layer (10 ) is nylon, cotton thread or cord.

[0027] In this embodiment, the inner surface layer 9 and the outer surface layer 11 of the airbag 1 are made of rubber material, which has high wear resistance and corrosion resistance. The middle layer 10 is made of nylon or cotton thread or cord, which increases the rigidity of the entire capsule body 1, and can avoid the excessive deformation of the capsule body 1 in uneven pipelines, which makes it difficult to pull, and also avoids being scratched by pipeline protrusions during use Inner surface layer 9 and air leakage.

Abstract

The invention discloses a plug device with ribs for an oil conveying pipe. The plug device comprises air bags, valves arranged on the air bags, a flexible pipe connected with the valves, an inflation pump connected to the tail end of the flexible pipe and a pressure gauge installed on the flexible pipe. The plug device further comprises setting ribs uniformly arranged on the outer surfaces of the air bags, Since an air bag is provided, the only thing needs to be is pumping out petroleum in the air bags on the two ends during emergency maintenance. The operation process is simple, labor-saving and time saving, and the work efficiency is substantially improved. The pressure gauge allows a worker to decide to aerate or discharge the air bags based on the pressure value on the pressure gauge, the setting ribs uniformly arranged on the outer surface of the air bags retain the profile of the air bag, so that the air bags can be well stuck in the petroleum pipe.

Description

technical field [0001] The invention relates to a water blocking air bag, in particular to a blocking device for oil pipelines with tensioned ribs. 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 a plugging device for oil pipelines with tensioned tendons. [0004] Technical scheme of the present invention is as follows: [0005] A blocking device for oil pipelines with tension, including an air bag, an air nozzle set o...
