Pipeline plugging airbag features Pipe plugging airbag construction steps
The pipeline sealing airbag is a multi-standard and multi-shape rubber product made of high-molecular synthetic materials such as rubber and fiber fabrics through high-temperature vulcanization process. It can be used for pipeline, culvert water delivery, drainage, and desilting maintenance. Rapid blocking of water flow in different pipe diameters, different planes, and different locations is an ideal tool for the transmission, drainage and sludge treatment of underground pipelines. Today, Xiao Bian gave everyone a talk about the related content of the pipeline sealing airbags . I hope to help you.
Pipe sealing airbag features
First, the characteristics of horizontal pipe sealing
1. Elliptical type, the area of ​​the contact pipe is not much, but it is easy to stuff into the pipe, and the water plugging effect is general.
2, simple operation, light weight, small size, economical and practical.
3, the airbag can be bent freely 180 degrees, there is a certain degree of corrosion resistance.
4, super-expansive.
Second, riser pipe sealing features
1, intuitive operation, direct observation pressure gauge pressure operation, according to standard pressure inflation.
2, the body size is small, easy to plug into the pipeline, economical and practical.
3, the airbag can be bent freely 180 degrees, and have a certain degree of corrosion resistance.
4, made of reinforced natural rubber, super expansive.
Third, pipeline plugging airbag construction steps
1. Preparation: First, combine the accessories of the inflator device of the municipal engineering circular conduit occluder and do the tool leak check. Inflate the airbag with an air pump. The air pressure must not exceed 0.15 MAP. Check the airbag for leaks.
2. Open the mouth of the pipe, and place the air bag from the mouth slowly and place it in the required position. Then inflate the pipe occluder and inflate it to a suitable pressure (usually 0.25MP). Note that the pipe occluder should be avoided at the riser fitting joint due to:
(1) There are joints on the inner wall of this place, which affects the tightness of water plugging.
(2) In order to prevent the pipe occluder from expanding to one side, the air pressure will not rise. If the inflation is continued, the pipe occluder will be broken.
(3) For municipal drainage pipes, it is required that the sand is clean and the inner wall is flat. No burrs are allowed. Otherwise, the watertightness of plugging water will be impaired, and even the capsules will be punctured.
(4) Pipe plugging devices of various specifications must be used within the corresponding pipelines, and they cannot be large and small.
3, in order to prevent the airbag and hose disengagement, in the airbag and hose interface application of iron wire or tightly tied in other ways.
4. When inflating the airbag with the inflator pump, when the airbag is to be completed, the air volume of the inflator must be turned off. It is not possible to continue inflating the airbag in large numbers to prevent airbag blasting and cause an accident.
5. In the process of transporting the airbag, the airbag must not be dragged to prevent damage to the outer wall of the airbag.
6, in the project work, we must always pay attention to the airbag pressure value, if the airbag pressure value is very slow decline, you do not have to stop the operation, continue to use air pump to fill the air to the standard air pressure, after the completion of the work in the inspection Where airbags or fittings leak.
The above is the related content of the pipeline sealing airbag, I hope to help you. For more information on the pipeline, please continue to pay attention to this site information.
