Description

Technical Field

[0001] This utility model relates to the field of fire simulation technology, specifically to a fuel supply system for fire training. Background Technology

[0002] When fire brigades conduct fire simulation training, diesel fuel is used as a primary fuel. The current solution is to set up a fuel storage tank in the fuel equipment room, and then use a booster pump to deliver fuel to the training area through the main fuel pipeline, and then deliver fuel to each fire simulation training facility through branch fuel pipelines.

[0003] When multiple fire simulation training facilities are turned on in sequence, the pressure in the fuel delivery pipe will drop in stages, causing a sharp decrease in the amount of fuel supplied to each fire simulation training facility, resulting in smaller flames or even extinguishing them. When the training ends and each fire simulation training facility is turned off in sequence, the pressure in the main fuel pipe will rise sharply, which may exceed the design pressure of the pipeline in severe cases, posing a risk of high-pressure rupture of the pipeline. Summary of the Invention
