1. Municipal drainage pipeline water blocking airbag The pipeline blocking airbag is also called the water blocking airbag. The plugging airbag is made of high-quality rubber and fiber reinforcement after vulcanization. It has good anti-expansion strength, elasticity and flexibility, and the sealing airbag can meet the use of various working conditions. And the operation is simple, with good aging resistance and long service life. Working principle: The working principle of the water blocking airbag is to use a pipeline made of high-quality rubber to block the airbag to expand it by inflation. When the gas pressure in the water blocking airbag reaches the specified requirements, the water blocking airbag fills the entire pipeline section. , using the frictional force generated by the wall of the airbag and the pipeline to block the leakage of water, so as to achieve the purpose of no water seepage in the target pipe section. Features: The plugging airbag is especially suitable for the maintenance and testing work such as closed water test, closed air test, leak point search, temporary water blocking for pipeline maintenance after sealing the drainage pipeline. The pipeline blocking airbag is mainly aimed at the pipeline blocking of horizontal pipelines (ie horizontal pipelines), Pipeline blcoking airbag characterized : 1. Oval type, the contact area of the pipeline is not much, but it is easy to plug into the pipeline, and the water blocking effect is average. 2. Simple operation, light weight, small body size, economical and practical. 3. The airbag can be bent 180 degrees freely and has certain corrosion resistance. 4.
