At present, pipelines are widely used as devices for transporting gas, liquid or fluid with solid particles. Such as a tap water pipeline, a gas pipeline, a sewage pipeline, etc. When the pipeline is installed, because the length of a single pipeline is limited, a plurality of pipelines are often required to be connected for use, and in order to facilitate the connection of the pipelines, the pipeline connector is invented.

The pipeline connector is used for being connected between two pipelines in need to the noose to this reaches the function of sealed pressure-bearing, makes intercommunication between each pipeline, and pipeline connector extensively is used for the pipe connection of different materials in trades such as oil, chemical industry, shipbuilding, platform, electric power, light industry, municipal administration and mechanical equipment.

However, the conventional pipe connectors used at present do not have fireproof performance, and cannot be used in occasions with fireproof requirements. Even if the pipe connector is used, the sealing material in the pipe connector is carbonized by high temperature generated by combustion when a fire occurs, and the locking member of the pipe connector falls off, so that the sealing effect cannot be achieved. The medium transported in the pipeline leaks, which causes greater safety accidents and economic losses.

Therefore, there is a need in the art to develop a new protection device for a connection portion, which has a simple structure, is used outside a pipe connector, and mainly plays a role of protecting a locking member on the pipe connector to prevent the pipe connector from aging or falling off when exposed to a fire.
