Common type: All kinds of water blocking airbags must use the corresponding size of the pipeline, not small and not large.

General purpose: expansion, quality effect is stronger than the ordinary type, the airbag can be used within the specified pipeline range.

The working principle of the pipeline waterproof airbag is to use high-quality rubber tubes to prevent the airbag from expanding. When the gas pressure in the water blocking bag reaches the specified requirements, the water blocking bag fills the entire pipe section and uses the pipe seal. The friction created by the wall of the airbag and the pipe prevents water leakage so that no water can seep out in the target pipe section.

Pipe water block bag for pipes:

1. Urban sewage pipes; Sewage pipes barely run. If the sewage line is blocked or needs to be unblocked, the air bag is blocked by the pipe, the pipe at both ends is blocked to prevent the flow of water back, and then the blocked part of the pipe can be unblocked.

2. Toilet (building waterproof layer) closed water test; The closed water test of the waterproof layer of the building needs to use the blocked tube air bag. In the sealed water test, the pipeline of the waterproof layer needs to be filled with water, and then the nozzle of the airbag is sealed with the pipeline to see whether there is water seepage for 24 hours.

3. The airbag of the high-rise building pipeline is blocked, and the water blocking air bag is sent by the inspection port. The water blocking air bag is inflated and filled with water for inspection; If the pipe has holes or holes, water leakage can be seen.

4. Check the floor drain; Open the floor drain to catch the bowl, insert the airbag into the floor drain, and pour the water onto the ground after inflating. If a floor drain is installed, the hole will not be filled according to regulations and water will leak from the floor drain.

5. Other pipelines, such as water pipes, gas pipes, gas pipes, rain pipes, sewage pipes, chemical pipes, ventilation pipes, etc., all adopt the same method.

Pipe clogging airbags have complete models and a wide range of applications. They can be used for various materials such as plastic pipes such as pe/pvc, building standpipes, municipal sewage pipes, fiberglass pipes, bellows, drains and sewers. As well as the construction of municipal unit management offices, water bureaus, sewage treatment plants, drainage stations and other projects in various provinces and cities, mainly used for temporary sealing of waterproof sealing work such as pipeline/pipeline sealing test/pipeline leak inspection and maintenance. It worked well.
