The object of the present invention is achieved like this: a kind of pipeline band water welded airbag, it includes air bag, is provided with at least one ring air bag flange collar around air bag on air bag, air bag is tightly connected with exhaust apparatus, air inlet pipe is communicated with air bag by the air admission hole on air bag, suction nozzle is installed in air inlet pipe, or uses suction nozzle directly to communicate with air bag；Described exhaust apparatus includes that air bleeding valve main body, air bleeding valve main body match with exhaust valve cap, air bleeding valve main body is provided with exhaust outlet, being provided with spring on exhaust valve spindle, exhaust valve spindle by the casing limit being fixed on exhaust valve cap, is fastened on exhaust valve cap center by spring by spring；Exhaust valve spindle front end is exhaust stopple, and exhaust stopple matches with venthole；Being set with sealing dividing plate on exhaust valve spindle, exhaust valve spindle rear end is connected with fixing link, and fixing link is connected with pull rope.
The first sealing ring it is provided with beyond the Great Wall at steam vent.
It is provided with the second sealing ring on dividing plate sealing.
Described air bag is rubber pneumatic bag.
It is additionally provided with moveable hook between fixing link and pull rope.
Described air bag and air bag flange collar are integral type structure.
Utilize the method that above-mentioned air bag carries out the welding of pipeline band water,
Air bag is put into band waterpipe to be welded, is inflated in air bag by air inlet pipe and suction nozzle, make air bag expand and be close to tube wall to reach to block the purpose of current；It is then placed in welding plate, when both sides pipe joint temperature can be welded, removes welding plate, the moveable hook that connection has pull rope is suspended on the fixing link of air bags valve shaft along pipeline to be welded, and starts welded pipe line, after having welded, pulling traction rope, spring in exhaust valve spindle tightens up, and the exhaust stopple on venthole position is opened, and the air in air bag is discharged from venthole, air bag volume is made to reduce, no longer it is close to the inwall of pipeline, air bag can be pulled out from pipeline, complete welding.
The pipeline band water welded airbag of present invention offer and welding method, utilize the air bag with flange collar can isolate water source, thus reach convenient, fast, effectively realize the purpose of pipeline band water welding.Utilize this device to considerably reduce construction cost, improve operating efficiency, ensure the welding quality of pipeline simultaneously, building water supply and drainage pipeline welding has important using value.
The air bag flange collar of the present invention is integrated with air bag, and both are firmly combined with, and flange collar can make air bag be attached to inner-walls of duct more closely, prevents from leaking.
The spring of the present invention can fix exhaust valve spindle by the casing limit being fixed on exhaust valve cap, sleeve pipe, makes the exhaust stopple on exhaust valve spindle be directed at venthole accurately, keeps smooth gas discharge.
