The diagrams show how a fire-extinguisher works.
The diagram shows a typical design of a fire extinguisher and its operation. Generally, this extinguisher is a sturdy metal cylinder which comprises of some simple components, and is filled with water which is used to extinguish small fires through some uncomplicated steps.
In this extinguisher, a plastic siphon tube leads from the bottom to the top of the extinguisher. A spring-mounted valve blocks the passageway from the siphon to the nozzle. At the top of the cylinder, there is a smaller cylinder filled with a compressed gas. A release valve keeps the compressed gas from escaping.
To use the extinguisher, the safety pin must be pulled out and the operating lever must be depressed. Then, the lever pushes on an actuating rod, which presses the spring-mounted valve down to open up the passage to the nozzle. The bottom of the actuating rod has a sharp point, which pierces the gas cylinder release valve. The compressed gas escapes, applying downward pressure on the water. This drives the water up the siphon and out the nozzle with considerable force.
