Embodiment
Further describe below in conjunction with accompanying drawing.
Embodiment 1:
As Fig. 1-Fig. 9, implement shutoff air bag in the utility model pipe leakage, comprise sealing mechanism, deflector, retaining mechanism and fixed structure.
Wherein, sealing mechanism comprises shutoff air bag 7; Deflector comprises water conservancy diversion pipe nipple 1, water conservancy diversion ball valve 2, sealing gasket 5, and wherein the water conservancy diversion pipe nipple can external honeycomb duct; Retaining mechanism comprises the gas-charging connection 3 of hollow shaft housing 4 and its left side; Fixed mechanism comprises air bag clamping sleeve 6, cone-shaped flange lid 8.
Wherein, to connect be by being threaded, more together by the water conservancy diversion ball valve screw 2-1 place that is threaded in left side on the hollow shaft housing 4 on the water conservancy diversion ball valve 2 by water conservancy diversion pipe nipple 1 and water conservancy diversion ball valve 2 for described deflector; The handle of water conservancy diversion ball valve 2 is downwards for closing.The connection of shutoff key component is being enclosed within 4-1 place on the left side of air bag clamping sleeve 6 along the 6-1 place in the left side of shutoff air bag 7, the 4-2 place that is enclosed within along the 6-3 place in shutoff air bag 7 right on the right side of air bag clamping sleeve 6, and make shutoff air bag 7 contain air bag clamping sleeve 6 fully, and make the inner headed face of its formation smooth, then be enclosed within on the periphery of axle sleeve, and make the left end of air bag be close to shaft shoulder place at hollow shaft housing 4 coating the right-hand member of good air bag clamping sleeve 6 by hollow shaft housing 4.Guarantee that for making inflation smooth and easy, marking during installation hole on the air bag clamping sleeve 6 and airslide 4-3 place align the 2-3 place airflow hole on the hollow shaft housing 4.With blind flange through hole and the blind flange screw at 2-4 place of four socket head screws 9 by the 8-1 place cone-shaped flange lid 8 is fixed on the right side of hollow shaft housing 4 at last, makes the axial seal of shutoff air bag 7 at hollow shaft housing 4.
As Fig. 1-Fig. 9, implement the rapid plugging method of blocking device in the utility model pipe leakage, this method is after sealing mechanism, deflector, retaining mechanism and fixed structure are installed together, at first to connect honeycomb duct on water conservancy diversion pipe nipple 1, connects gas tube on gas-charging connection 3.Shutoff air bag in the whole series is installed in the risk source capsule road 10, opens water conservancy diversion ball valve 2, be inflated in the shutoff air bag 7 by gas tube then, close water conservancy diversion ball valve 2 at last, realize the quick blocking in risk source capsule road 10.As the needs water conservancy diversion.Opening water conservancy diversion ball valve 2 gets final product.
Shutoff and water conservancy diversion air bag in the described pipeline, can directly apply to pipeline leaks for straight mouthful, in situation from pipe end pipeline external leakage more nearby, when leaking as there is the crack to locate generation when pipeline external surface, this device advanced in risk source capsule road 10 fracture ports locate with intact of the pipeline of lining, open water conservancy diversion ball valve 2, be inflated in the shutoff air bag 7 by gas-charging connection 3 external gas-filled pumps then, block or the isolated port rent carries out quick blocking; When certain part in the middle of the pipeline takes place to leak, can push the position that needs shutoff in the pipeline, thereby carry out quick blocking in pipeline, shutoff air bag 7 being inflated then by gas tube by external stream guiding tube handle assembly.Should earlier water conservancy diversion ball valve 2 be opened with pressure release when shutoff, the flow resistance that is subjected to when reducing advancing means after inflation finishes, re-uses special tool and closes water conservancy diversion ball valve 2.Because of shutoff air bag 7 is the same inflator of rubber tyre, therefore can adapt to pipeline even large-scale pipeline in the certain diameter scope, adaptability is stronger.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
