The pipe sealing bag made of high quality rubber expands the pipe sealing bag by inflating it. When the gas pressure in the water sealing bag reaches the specified requirements, the water sealing bag fills the entire pipe section and uses the friction generated by the pipe sealing bag wall and the pipe to block the water leakage, so as to quickly block the water flow in the target pipe section by inflating and expanding. To achieve the purpose of no seepage.

Pipeline sealing bag is a kind of multi-specification, multi-shape rubber product made of polymer synthetic materials such as rubber and fiber fabric by high temperature vulcanization process for pipeline, culvert water transmission, sewage, desilting maintenance. It can quickly block water flow in different pipe diameters, different planes and different positions, and is an ideal tool for underground pipeline transport and drainage and silt treatment.

Transverse pipe plugging characteristics

1, oval type, contact pipe area is not much, but easy to plug into the pipe, water blocking effect is general.

2, simple operation, light weight, small body size, economic and practical.

3, the air bag can be freely bent 180 degrees, has a certain corrosion resistance.

4, super expansion.

Riser pipe plugging characteristics

1, the operation is intuitive, directly observe the pressure operation of the pressure gauge, and inflate according to the standard pressure.

2, the body size is small, easy to plug into the pipeline, economic and practical.

3, the air bag can be freely bent 180 degrees, and has a certain corrosion resistance.

4, made of enhanced natural rubber, super expansion.

The pipe water blocking airbag is suitable for water closing test, air closing test, leak point finding, temporary water blocking and other maintenance test work after sealing the drainage pipe.

1. Preparation: First combine the accessories of the municipal engineering circular pipe stopper inflation device to check the leakage of tools. Use the air pump to inflate the air bag, the air pressure shall not exceed 0.15MPA, and check whether the air bag leaks.

2. Open the pipe opening, place the airbag slowly inside the desired position from the mouth, and then inflate the pipe stopper to the appropriate pressure (generally 0.25MP). Note that pipe stoppers should be avoided at riser fittings joints for the following reasons:

(1) There are joints in the inner wall, affecting the tightness of water plugging.

(2) So as not to expand the pipeline sealer to one side, the air pressure can not be played up, if it continues to inflate, the pipeline sealer will be broken.

(3) For municipal drainage pipes, the sand is required to be clean, the inner wall is smooth, and no burrs are allowed, otherwise it will affect the sealing of water plugging and even puncture the capsule.

(4) Various specifications of the pipeline stopper must be used in the corresponding pipeline, can not be small to large.

3, in order to prevent the air bag and the hose from coming off, the air bag and the hose interface should be tied with wire or other ways.

4, When the air pump is used to inflate the air bag to complete, the air pump should be turned off a little, can not continue to inflate a large amount, to prevent the air bag explosion, causing accidents.

5, in the process of handling the airbag, do not drag the airbag to prevent damage to the outer wall of the airbag.

6, in the engineering operation, we should always pay attention to the pressure value of the air bag, if the pressure value of the air bag is slowly declining, it is unnecessary to stop the operation, continue to use the air pump to fill the air bag to the standard air pressure, and so on, after the completion of the operation, check where the air bag or accessories leak.

Put the sealing airbag into the pipe mouth to be blocked. The length of the releasing pipe is the length of the sealing air bag, and then the compressed air is injected into the specified pressure through the air intake valve, and the construction can be carried out. After the construction is completed, the air intake valve is opened to release air and the sealing air bag is removed.

1, check whether the surface of the air bag is clean, there is no attached dirt, whether it is intact, fill a small amount of gas to check the parts and the air bag for air leakage. Make sure that it is normal before entering the pipeline for plugging operation.

2, inspection of the pipeline: before sealing, check whether the inner wall of the pipeline is smooth and smooth, there are no prominent burrs, glass, stones and other sharp objects, if there is immediately removed, so as not to puncture the air bag, the air bag should be placed horizontally after being placed in the pipeline, do not twist it, so as not to trap the gas to blow the air bag.

3, do the air bag accessories connection and leakage check: first of all, the pipe water plugging air bag auxiliary inflatable accessories are connected, after the connection is completed, do tools to check whether there is a leak. Stretch the pipe water plugging airbag, connect it with the accessory accessories, and fill it until it is basically full. Turn off the air check valve when the pressure gauge pointer reaches 0.03MPA. Apply soapy water evenly on the surface of the airbag and observe whether there is any air leakage.
