Description
Technical field
The utility model relates to a kind of air bag dress, is specifically related to a kind of pipeline band water welded airbag.
Background technology
Pipeline is widely used in building water supply and sewerage engineering, and pipeline welding is the key technology that pipe-line system builds.Construction, maintenance are speedily carried out rescue work in process, although cut off the water supply by pipeline leading portion valve, more than pipeline, water still can affect welding, if directly weld, can cause solder joint or welding plate position local temperature inequality, cause rosin joint, the hidden danger of quality such as solder skip.At present also not used for the specific purpose tool of pipeline band water welding, the welding of conventional belt water and installation method mainly contain two kinds: the first, with plug current source, weld again after in-pipe flow is clean, the defect of the method is to need to block multiple source, wastes time and energy; Have water in transverse tube pipeline, rock along with pipeline during welding and flow out.The second, clogs water side in welding with stopper.The method defect is, if take out stopper to after pipeline heating, after stopper, water can flow out, and causes that solder side temperature is too low cannot weld; If get after welding, then stopper can not be got out again, needs difficult dredging.
Summary of the invention
The purpose of this utility model is to provide a kind of safe and convenient to use, the pipeline band water welded airbag that reliability is high and the method utilizing this air bag to weld band waterpipe.
The purpose of this utility model is achieved in that a kind of pipeline band water welded airbag, it comprises air bag, on air bag, is provided with the air bag flange collar of at least one ring around air bag, air bag and exhaust apparatus are tightly connected, air inlet pipe is communicated with air bag by the air admission hole on air bag, air inlet pipe is provided with suction nozzle, or adopts suction nozzle directly to communicate with air bag; Described exhaust apparatus comprises air bleeding valve main body, air bleeding valve main body matches with exhaust valve cap, air bleeding valve main body is provided with exhaust outlet, exhaust valve spindle is provided with spring, and exhaust valve spindle, by being fixed on the casing limit on exhaust valve cap, is fastened on exhaust valve cap center by spring by spring; Exhaust valve spindle front end, for discharging air plug, is discharged air plug and is matched with venthole; Exhaust valve spindle is set with seal cover board, and exhaust valve spindle rear end is connected with fixing link, and fixing link is connected with pull rope.
The first sealing ring is provided with beyond the Great Wall at venthole.
Seal cover board is provided with the second sealing ring.
Described air bag is rubber pneumatic bag.
Also moveable hook is provided with between fixing link and pull rope.
Described air bag and air bag flange collar are integral type structure.
Above-mentioned air bag is utilized to carry out the method for pipeline band water welding,
Air bag is put into the band waterpipe that will weld, inflated in air bag by air inlet pipe and suction nozzle, air bag is expanded and is close to tube wall to reach the object blocking current; Then put into welding plate, when both sides pipe joint temperature can be welded, go out welding plate, the moveable hook being connected with pull rope is suspended on the fixing link of air bags valve shaft along the pipeline that will weld, 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 reduced, no longer be close to the inwall of pipeline, air bag can be pulled out from pipeline, complete welding.
The pipeline band water welded airbag that the utility model provides and welding method, utilize the air bag with flange collar to isolate water source, thus reach convenient, fast, effectively realize pipeline band water welding object.Utilize this device to considerably reduce construction cost, increase work efficiency, ensure the welding quality of pipeline simultaneously, in building water supply and drainage pipeline welding, there is important using value.
Air bag flange collar of the present utility model and air bag are integrated, and both combine firmly, and flange collar can make air bag be attached to inner-walls of duct more closely, prevents from leaking.
Spring of the present utility model is by being fixed on the casing limit on exhaust valve cap, and sleeve pipe can fix exhaust valve spindle, makes the stopple of giving vent to anger on exhaust valve spindle aim at venthole accurately, keeps smooth gas discharge.
