Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline technology, and in particular to a quick connection structure for fire protection pipelines. Background Technology

[0002] Fire protection piping is specifically designed for firefighting. Its main function is to connect firefighting equipment and transport water, gas, or other media for firefighting. Fire protection piping must be pressure-resistant, corrosion-resistant, and high-temperature-resistant to ensure effective water supply and support for firefighting efforts during a fire.

[0003] In the fields of fire protection pipeline construction and plumbing pipeline construction, it is often necessary to connect two pipelines in series. The existing fire protection pipelines mainly use malleable iron galvanized pipe joints to connect the two pipelines. The pipeline and the pipe joint are connected by threads, and sealing tape is wrapped around the threaded connection for sealing. However, this connection method has high requirements for the processing precision of the pipeline. On the one hand, the end face of the pipeline must be processed flat. If the processing is not perfect, it will cause uneven pressure on the sealing ring and side leakage. On the other hand, the pipeline must not be bent or deformed. If it is bent or deformed, the ends will be difficult to align, and the sealing ring will not seal properly, resulting in side leakage.

[0004] Therefore, we propose a quick-connection structure for fire protection pipes to solve the above problems. Utility Model Content

[0007] Preferably, the protective sleeve has holes at both the front and rear ends that are compatible with the fire-fighting pipeline, and grooves are formed on both sides of the protective sleeve, with fixing plates fixedly installed inside the grooves.

[0008] Preferably, the surfaces of the first mounting plate and the second mounting plate are provided with two sets of threaded holes, and two sets of threaded pins are inserted into the threaded holes.
