Sprinkleripään

Sprinkleripään is a Finnish term that translates to "sprinkler head" in English. It refers to the device at the end of a sprinkler pipe that disperses water in a fire suppression system. These heads are designed to activate automatically when a certain temperature is reached, releasing water to control or extinguish a fire.

There are various types of sprinkler heads, each with specific applications. Common types include upright sprinkler heads, which spray water downwards from an elevated position, and pendant sprinkler heads, which hang downwards from the pipe. Recessed sprinkler heads are designed to be flush with the ceiling for aesthetic purposes, while sidewall sprinkler heads are mounted on walls. The design and placement of sprinkler heads are critical for the effective operation of a fire sprinkler system.

The activation mechanism of a sprinkler head typically involves a heat-sensitive element, such as a glass bulb filled with a liquid or a fusible link made of metal. When the ambient temperature around the sprinkler head rises to its activation point, this element breaks or melts, opening the valve and allowing water to flow out. The specific temperature at which a sprinkler head activates is indicated by a color-coded liquid in the glass bulb or a marking on the fusible link. This ensures that only the sprinkler heads in the immediate vicinity of the fire are activated, minimizing water damage to unaffected areas.
