Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel pipelines, in particular to a multi-channel hydrogen fuel cell pipeline. Background Art

[0002] Pipeline refers to the pipe that transmits the working fluid in the hydraulic system. Compared with pipeline, pipeline is a reasonably arranged pipeline system. Because of the flexibility of pipeline, pipeline is often used in hydraulic system and other mechanical equipment driven by liquid.

[0003] After searching, Chinese patent number CN217927688U discloses a shunt hydrogen fuel cell pipeline, which belongs to the field of pipeline technology, including a main body, shunt pipes are installed on the upper and lower sides of the main body, and discharge pipes are arranged on the upper and lower sides of the main body and at positions corresponding to the shunt pipes. The two discharge pipes are connected to the main body through two rotating adjustment devices, and a temperature measuring device is installed on one side of the main body; the utility model provides a rotating adjustment device so that the staff can adjust the angle of the discharge pipe when necessary, so as to better meet the work needs in different situations, thereby improving the working capacity of the pipeline; the utility model provides a temperature measuring device so that the staff can detect the temperature of the hydrogen fuel through simple operation when necessary, thereby reducing the possibility of accidents caused by high temperature, thereby improving the practicality of the pipeline.
