The special-shaped membrane structure is welded by Shanghai Jiuluo water plugging air bag welding machine, which uses high frequency vibration instantaneous heating to act on the water plugging air bag. It can make the material molecules reach the welding temperature in an instant for welding, with high welding strength and firmness. And Shanghai Jiuluo special-shaped membrane structure welding machine can handle corner welding and other positions, which can save labor cost.

With 18 years of equipment R & D and manufacturing experience, Jiuluo technology is mature and the output power of the equipment is stable. It can be customized according to different requirements of customers' products.

Water plugging air bag is a kind of multi-specification and multi- shape product made of polymer synthetic material, which is used for water delivery, sewage discharge and desilting maintenance of pipes and culverts. It can quickly block water flow in different pipe diameters, planes and positions, and is an ideal tool for underground pipes to carry out water transmission, drainage and sludge treatment.

Working principle of water plugging air bag

It is to inflate the air bag by means of inflation. When the air pressure in the air bag reaches the specified requirements, the air bag will fill the whole pipe section, and the friction force generated by the air bag wall and the pipe will be used to block the water leakage, so as to achieve the goal of no water seepage in the target pipe section.

The air bag is especially suitable for the maintenance and test work such as closed water test, closed air test, leakage point search, temporary water plugging for pipeline maintenance after the drainage pipeline is sealed.

Usage of water plugging air bag

Put the water plugging air bag at the pipe mouth to be blocked, the length of the pipe is the length of the air bag, and then rush the compressed air through the air inlet valve to the specified pressure, then the construction can be carried out. After the construction, open the air inlet valve to release the air and take out the air bag.
