▎ 摘　　要

NOVELTY - Blocking type pipeline maintenance airbag comprises main body, where outer wall of main body is provided with the graphene air bag, and the graphene air bag is set in the electrolysis chamber main body (6) and outer wall of electrolysis chamber main body is provided with the extruding bag (10). The two ends of extruding bag is provided with a side air bag inlet valve. The electrolysis chamber main body is provided with a water inlet valve, where one side of water inlet valve is provided with an electrode unit (9), one side of electrode unit is provided with a first water-gas separating film (7), and the other side of the electrode unit is provided with a second water-gas separating film. The second water-gas separating film (13) is provided with a gas cavity. USE - Blocking type pipeline maintenance airbag. ADVANTAGE - The blocking type pipeline maintenance airbag has simple structure, rational design, high strength, air tightness and adjusts according to size and shape of conduit and wide suitability, which effectively block pipe, and is convenient to maintain. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of blocking type pipeline maintenance airbag.
