kuivaputkijärjestelmä

Kuivaputkijärjestelmä, also known as a dry pipe sprinkler system, is a type of automatic fire sprinkler system that is designed to be installed in areas where temperatures may fall below freezing. Unlike wet pipe systems where the pipes are constantly filled with water, dry pipe systems have their pipes filled with pressurized air or nitrogen.

When a fire occurs, the heat causes the sprinkler heads to activate and open. This allows the pressurized air or nitrogen in the pipes to escape. As the pressure drops, a dry pipe valve, located in a heated area, opens, allowing water to flow into the sprinkler pipes and out of the activated sprinkler heads. This delay in water delivery is a key difference from wet pipe systems, making dry pipe systems more suitable for unheated environments like warehouses, parking garages, and unheated attics.

The components of a kuivaputkijärjestelmä include sprinkler heads, piping, a dry pipe valve, an alarm check valve, and a water supply. The system requires a reliable source of pressurized air or nitrogen and a mechanism for maintaining that pressure. While effective in preventing freezing, the delay in water discharge means that dry pipe systems may not be the best choice for situations where rapid fire suppression is critical. Regular inspection and maintenance are crucial to ensure the proper functioning of the dry pipe valve and the entire system.
