Embodiment Construction

[0009] As shown in the figure, the present invention has an airbag body 3, and a trachea 7 is drawn out in the airbag body 3, and ball valves 6 and 8 are provided on the trachea body 7. The middle part of said airbag body 3 is cylindrical, and the two ends are semicircular or Oval, and the airbag body 3 is made of inner skin 31, middle layer 32 and outer skin 33, said inner and outer skins 31 and 33 are rubber sheets, middle layer 32 is nylon cord or cotton cord, to increase airbag The intensity of body is provided with pull rod 2,4 at the two ends of air bag body 3, and said pull rod 2 and 4 are respectively provided with suspension ring 1 and 5. An inner rubber sheet 10 and an outer rubber sheet 9 are provided on both ends of the airbag body 3 corresponding to the pull rods 2 and 4 to reinforce the airbag body 3 .

[0010] In actual use, take two rubber inflatable water blocking airbags and place them at both ends of the accident section of the water supply pipeline along th...

Abstract

The invention is a rubber air water stopping air cell, including an air cell body, leading an air tube out of the body and there is a ball valve set on the air tube, where the middle of the body is cylindrical and two ends are semicircular or elliptic, and the body is composed of inner surface layer, middle layer and outer surface layer, there are pull rods set at the two ends of the body, respectively, where the pull rod is set with a ring. Its advantage: when making urgent repair on pipe obstacles, it can largely reduce quantity of pumping water and the operating procedure is simple, and it saves time and labor, and does not influence industrial production and normal water supply to townsmen.

Description

technical field [0001] The invention belongs to a device used for emergency repair of tap water supply pipelines with water, and particularly relates to a rubber inflatable water blocking air bag. Background technique [0002] At present, in the emergency repair of large-caliber pipeline accidents in the water supply industry, it is generally used to close the adjacent valves at both ends of the accident section, and then pump out the water stored in this pipe section. Sometimes because the valve is not tight, water leakage occurs, and the water cannot be pumped out, so the valve of the adjacent upper section of the pipeline has to be closed to pump water, and then emergency repairs can be carried out. Like this, cause accident section pipeline and upstream pipeline to stop water supply, pumping time is long, waste water resources, have a strong impact on urban industrial production and urban residents' domestic water supply. Contents of the invention [0003] The purpose...
