[0002] Pipelines are mostly used for the transportation of gas or liquid. During the transportation of gas or liquid, pipelines are very convenient to use. However, in the process of liquid transportation, if the pipeline is damaged and the liquid source cannot be closed, due to the high pressure of the liquid source, it is difficult to To connect the pipelines, when connecting pipelines under pressure, it is usually necessary to use a rubber plug to seal the pipeline first, and then connect the pipelines. However, this method is difficult to work in elbow connections and narrow areas. Pipelines that can still be connected under pressure during operation still need continuous research

Embodiment Construction
[0020] combined with Figure 1-5 In the above-mentioned multi-diameter bending pipe connection equipment under pressure, the bending mechanism 26 cooperates with the pumping mechanism 27 to realize the pressure connection between the pipe 10 and the elbow 11, and the bending mechanism 26 is used to adapt to the shape of the pipe. The pumping mechanism 27 is used to block the liquid inside the pipeline 10;
[0021] The bending mechanism 26 includes a plurality of articulated tubes 12, and two adjacent articulated tubes 12 are rotatably connected to the articulated shaft 14, and a torsion spring 25 is arranged on the outside of the articulated shaft 14, and the two ends of the torsion spring 25 are respectively connected to the two articulated shafts. The two hinged tubes 12 are fixedly connected, the inner of the hinged tubes 12 is hollow, and the hinged tube 12 at one end is longer.
[0022] Beneficially, the number of the hinged tubes 12 can be increased by itself according ...

The invention discloses multi-pipe-diameter under-pressure bent pipe connecting equipment. A bending mechanism and an air pumping mechanism are matched to achieve under-pressure connection of a pipeline and a bent pipe, the bending mechanism is used for adapting to the shape of the pipeline, the air pumping mechanism is used for blocking liquid in the pipeline, the bending mechanism comprises a plurality of hinged pipes, every two adjacent hinged pipes are rotationally connected with a hinge shaft, and a torsional spring is arranged on the outer side of each hinge shaft. According to the multi-pipe-diameter under-pressure bent pipe connecting equipment, the bending mechanism can be used for adapting to the shape of the bent pipe and a narrow bend area, the air pumping mechanism is used for pumping air to a rubber balloon, the rubber balloon is used for blocking the pipeline after being expanded to achieve pipeline sealing, and an air releasing mechanism is used for releasing air in the rubber balloon after pipe connection is completed, and the equipment is moved out.
Description
technical field [0001] The invention relates to the related field of pipelines, in particular to a connection device for multi-diameter bent pipes with pressure. Background technique [0002] Pipelines are mostly used for the transportation of gas or liquid. During the transportation of gas or liquid, pipelines are very convenient to use. However, in the process of liquid transportation, if the pipeline is damaged and the liquid source cannot be closed, due to the high pressure of the liquid source, it is difficult to To connect the pipelines, when connecting pipelines under pressure, it is usually necessary to use a rubber plug to seal the pipeline first, and then connect the pipelines. However, this method is difficult to work in elbow connections and narrow areas. It is still necessary to continue to study whether the pipeline can still be connected under pressure during operation.
