Abstract
The utility model relates to a pipeline sealing device which is provided with a sealing cover in a wheel hub shape, wherein the sealing cover is sheathed with a movable clamping sleeve. An inflation sealing tyre is arranged between the sealing cover and the movable clamping sleeve, and the outer circle of the sealing tyre is provided with a flexible rubber layer which is tightly contacted with a pipeline inner wall after inflation to seal a pipeline. The inner side of the sealing tyre is provided with an inflation and deflation valve, and an external air source. The cover surface of the sealing cover is provided with a water supply and discharge interface which is used for supplying and discharging water. The pipeline sealing device has the advantages of simple use, convenient assembly and disassembly, high sealing speed, good effect, repeatable use, material saving and labor intensity reduction, and the utility model can be universally used for the pipelines of different pipe diameters in a certain range, when the pipe diameter is increased, only the sealing tyre is required to be replaced. The utility model is suitable for sealing the pipelines of water-close tests of rain and sewage pipelines without pressure, and can also be used for sealing the pipelines of coal gas, heat, and water supplying risk prevention, desilting the sewage pipelines and temporarily sealing the pipelines.
Description
Technical field:
The utility model relates to the pipe plugging technical field, a kind of pipe plugging device.
Background technique:
At present, in pipeline construction, no pressure piping is carried out closed-water test, adopt usually and build the thick brick wall of 24cm, cement sand plaster shutoff.Must wait until after slush reaches sufficient intensity and can pour water, as occur leaking, need and to carry out the quadric-plastering leak stopping after the water extraction, not only waste time and energy, and need the artificial plug of removing after test is finished, again the plug removed is risen to ground in the pipeline and do waste processing, both waste material, artificial, cost is high again, incurs loss through delay the duration.
Summary of the invention:
For overcoming the deficiency of existing pipe plugging technology, the utility model provides a kind of pipe plugging device, and this pipe plugging device can not only carry out quick blocking to pipeline, and plugging effect is good, can not produce rubbish, and is reusable.
For achieving the above object, the utility model adopts following technological scheme:
Described pipe plugging device, it has a hub-like capping, is set with movable cutting ferrule on the capping, and a gas-flow closure tire is arranged between capping and movable cutting ferrule.
Described pipe plugging device has a confession, drainage interface on the capping of its capping, there are suspension ring at the capping rear portion.
Described pipe plugging device, there is one deck soft rubber layer its sealed tire outer ring, the inboard have fill, outlet valve.
Described pipe plugging device, its movable cutting ferrule can adopt baffle plate also can adopt thread set on capping.
Described pipe plugging device, its sealed tire also can be cylindrical structure, the outside have fill, outlet valve.
The beneficial effects of the utility model are: this pipe plugging device uses simple, easy to loading and unloading, and different tube diameters can be general within the specific limits, and caliber increases, only need to change sealed tire, shutoff speed is fast, effective, and reusable, economical with materials reduces labor intensity.
