    Dry Alarm Valve

  Dry alarm valve is an important component of dry automatic sprinkler system, which is mainly composed of dry valve, hydraulic alarm, pressure switch and air pressure maintenance device.Dry automatic sprinkler system is a closed system developed on the basis of wet sprinkler system to meet the need of installing automatic sprinkler system in cold and high temperature places.

  Dry system adopts closed sprinkler head, which is usually filled with pressure gas (compressed air or nitrogen) in the side pipe network of the system.When there is a fire in the protection zone, the temperature will rise and the sprinkler head will feel the temperature, then the pressure gas will be released, which will lead to the decrease of the pressure on the side of the system pipe network. The pressure water on the side of the water supply will open a dry alarm valve and the system will sprinkler the fire.At the same time, a small amount of water flows through the alarm port to the hydraulic alarm and pressure switch to give alarm sound and alarm electrical signals.

  Dry system, inadequate water bar should be in a state of the pipeline, and filled with gas pressure, suitable for frozen dangerous due to environment temperature is too high and the water in the pipe may vaporize place fire protection, often used in ambient temperature below 4 ℃ or higher than 70 ℃.
