Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connectors, in particular to a pipeline connector for a water supply pipeline. Background Art

[0002] Pipe connectors for water supply pipes refer to components used to connect various parts of water supply pipes to ensure the integrity, sealing and stable operation of the pipe system. Pipe connectors for water supply pipes play an important role in ensuring the normal operation of the water supply system, improving the reliability and maintainability of the system, and repairing damaged parts of the pipe: When the pipe is partially damaged, the connector can be used to replace the damaged part and restore the normal function of the pipe.

[0003] In the prior art, pipe connections are difficult to connect and difficult to disassemble and repair. The reason is that the connection is directly welded. For example, flange connection is more complicated and the flange cost is relatively high. In addition, after the connection is left outdoors for a long time, it will be exposed for a long time, resulting in leakage, rust or rot at the connection.

In this utility model, a threaded rod and a U-shaped groove are provided, and the threaded rod is rotated toward the first water pipe, and the threaded rod passes through the inside of the U-shaped groove, and then the first connecting rod and the second connecting rod are tightly fitted by rotating the nut, and the silicone blocks on the inner sides of the first connecting rod and the second connecting rod are provided for waterproof protection to prevent leakage and the like.

[0005] In view of the above problems, existing patents have provided solutions, but existing water pipe connectors are troublesome to install. Some complex connectors require special tools and skills to be properly installed, which increases the difficulty of construction. In addition, impurities enter the pipe with the water flow and easily accumulate in narrow parts, causing pipe blockage. Insufficient sealing of the pipe connector will cause a drop in water pressure, affecting normal water supply.

[0006] Therefore, a pipe connector for a water supply pipe is proposed. Utility Model Content
