Description

A leak-stopping device with water and pressure for water supply pipeline maintenance

Technical field

The utility model relates to the technical field of water pipe repair and maintenance, and specifically relates to a water and pressure leak plugging device for water supply pipeline repair.

Background technique

Nowadays, water supply pipelines are laid underground. The water supply pipelines laid underground put forward higher requirements for the pipeline maintenance of the water supply units. The water supply units have a high leakage rate, resulting in a waste of water resources. When the pipelines leak, they need Use side leakage equipment to locate the leak point in a timely manner, and then excavate to expose the leak point. Based on the scope of the leak point and the size of the opening, determine whether the construction plan is pipeline replacement or leak plugging repair. Pipe replacement requires a large area of water outage. In rapidly developing cities, water outages require advance notification and will cause certain economic losses. Cutting off pipelines requires waiting for the water in the pipelines to flow out before construction, which results in high construction costs, waste of water resources, and low construction efficiency. Therefore, when a leakage point is discovered at this stage, the maintenance method is usually to use water and pressure. The highest leakage plugging device is to directly hug the leakage point of the pipe with a Huff joint. However, the structure of the Huff joint adopts an upper and lower structure. The pipe hoop and the inner sealing gasket squeeze the outer wall of the pipe. The sealing gasket is distributed around the inner circle of the pipe hoop. There is a gap between the middle part of the pipe hoop and the pipe, so that the water leaking from the pipe will continue to flow under the impact of pressure. If the sealing gasket is impacted, leakage will occur over time, resulting in poor sealing effect and short service life. Therefore, a water-and-pressure plugging device for water supply pipeline maintenance is designed to solve the problem of secondary leakage caused by the inability of Huff joints to effectively control water into the pipeline without replacement and maintenance of existing pipelines.
