The closed water bag is a very efficient and environmentally friendly device, which is widely used in various fields. With the continuous progress of science and technology and people's attention to environmental protection, the closed water bag has gradually become a necessary tool for major cities and industrial enterprises.

In urban construction, closed water bag can solve many problems in water pipe maintenance and construction. Traditional water pipe repairs require cutting off the water source and then welding or replacing the pipe, which is time-consuming and involves a lot of work. With a closed air bag, maintenance becomes easier and faster. When a water pipe needs to be repaired, it is only necessary to place the closed water bag in the position that needs to be repaired, inflate it to expand, form a block to the water flow, and then repair work. This not only saves a lot of time cost, but also avoids the waste of water, which plays a positive role in promoting the city's water-saving work.
