Description
Technical field
The utility model belongs to municipal technical field of tools, refers in particular to a kind of sewerage shutoff air bag.
Background technique
Pipeline plugging air bag is used for pipeline, culvert water delivery, blowdown, removes the maintenance of becoming silted up, when the gas pressure in shutoff air bag reaches regulation requirement, shutoff air bag fills up whole conduit section, the frictional force utilizing pipeline plugging air bag wall and pipeline to produce is blocked and is leaked, thus reach in target pipeline section and by inflation, current are blocked fast, reach the object without infiltration.Shutoff air bag does not have well-regulated shape under the state of not inflating, and especially after using, bleeds off internal gas, and the shape finally presented is also uncertain, but under normal circumstances, arrange cumbersome, and the space taken is larger.
Summary of the invention
The sewerage shutoff air bag that the purpose of this utility model is to provide a kind of foldable, is convenient to transport and stores.
The purpose of this utility model is achieved in that sewerage shutoff air bag, comprises air bag and end seat, end seat is provided with air valve, for inflation and venting, air valve is communicated with air bag, wherein, described air bag is provided with some folding patterns, folding pattern indentation, the air bag inwall that described folding pattern is corresponding is provided with stiffening plate, strengthens the folding line of folding pattern, enable air bag fast folding, the peak of described folding pattern is provided with ring rib, improves plugging effect, prevents infiltration.
According to upper described sewerage shutoff air bag, wherein, described end seat is also provided with handle, conveniently lays and move.
The utility model gives prominence to compared to existing technology and useful technique effect is: make the folding easier of air bag, folding efficiency is higher, reduces to take up room, and conveniently transports and stores.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model gas is completely insufficient;
Fig. 2 is the structural representation that the utility model is completely sufficient;
In figure: 10-air bag, 11-holds seat, 12-air valve, 13-folding pattern, 14-stiffening plate, 15-ring rib, 16-handle.
Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, see Fig. 1-2: sewerage shutoff air bag, comprise air bag 10 and end seat 11, end seat 11 is provided with air valve 12, for inflation and venting, air valve 12 is communicated with air bag 10, wherein, described air bag 10 is provided with some folding patterns 13, folding pattern 13 indentation, air bag 10 inwall of described folding pattern 13 correspondence is provided with stiffening plate 14, gap is left between stiffening plate 14, when being convenient to folding, stiffening plate 14 can superpose, enhance the folding line of folding pattern 13, make air bag 10 can fast folding, the peak of described folding pattern 13 is provided with ring rib 15, increase the frictional force with inner-walls of duct, improve plugging effect simultaneously, infiltration can be prevented.
Further optimization, described end seat 11 is also provided with handle 16, conveniently lays and move.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
