Referring to fig. 1 and fig. 2, the utility model provides a pair of gasbag pressurizer, including gasbag body 10 and air cock 20, gasbag body 10 is fusiformis, including two support areas 12 of middle shutoff district 11 and both sides, inside link up and integrated into one piece in shutoff district 11 and two support areas 12, and air cock 20 sets up the end in one of them support area 12, and air cock 20 connects gas tube 21, aerifys for gasbag body 10 through the gas tube, is equipped with the air flow control valve in the air cock 20, is convenient for control the inflation volume.
The air bag body 10 adopts a shuttle-shaped air bag structure, is convenient to be arranged in a pipeline and can be used for repairing the pipeline in a targeted manner. The plugging area 11 is used for providing support pressure for repairing damaged parts of the pipeline, and is beneficial to complete curing and uniform curing of the resin material. The supporting area 12 is used for monitoring the pressure value in the whole airbag body 10 and the fitting pressure degree of the inner wall of the pipeline in a key mode, so that the situation that the resin material layer becomes thin due to overlarge pressure and the repairing quality of the pipeline is affected is avoided, the situation that the resin material and the inner wall of the pipeline cannot be uniformly and powerfully fitted due to the fact that the pressure value is too small, the final repairing result is not uniform and the like is avoided.
The length of the blocking area 11 is more than twice of the sum of the lengths of the two supporting areas 12 at the two ends, and the structure ensures that the airbag body 1 has enough area to contact with the inner wall of the pipeline to realize the pressure supporting effect. The diameter of the plugging area 11 is basically the same, when the airbag body 10 is inflated, the plugging area can be uniformly attached to the inner wall of the pipeline, and the diameter of the supporting area 12 is gradually reduced from inside to outside to finally form a fusiform structure.
