How does automatic fog nozzle maintain consistent pressure?

The automatic fog nozzle maintains consistent pressure through its ability to adjust to varying flow rates while keeping the pressure at a steady level. This is achieved by the nozzle's design, which includes a pressure-regulating mechanism that detects changes in the water flow and instantly adjusts to maintain the desired pressure.

When water is discharged through the nozzle, if the flow rate increases or decreases, the nozzle automatically responds by modifying its intricate internal mechanisms to ensure that the output pressure remains stable. This capability is especially important in firefighting scenarios, where maintaining effective pressure can be crucial for effective water application and fire suppression.

In contrast, adjusting the water temperature, controlling the foam ratio, or altering the nozzle diameter do not directly address the maintenance of consistent pressure within the context of an automatic fog nozzle's primary function.
