The ZSFY pre-action device is an automatic sprinkler fire extinguishing device developed in recent years. It combines fire automatic detection and alarm technology with an automatic sprinkler fire extinguishing system, providing dual protection for the protected object. It is especially suitable for important places that are prone to freezing or where water damage is unacceptable, such as computer rooms, generator rooms, data rooms, historical archives, and high-rack warehouses. Before a fire occurs, the system's side pipeline is filled with compressed air, so the system has the characteristics of a dry system and can meet the needs of automatic sprinkler irrigation under high-temperature and freezing conditions.
The ZSFM diaphragm deluge valve consists of a main valve, hydraulic alarm bell, pressure switch, manual opening valve, solenoid valve, manual reset valve, resetter, and control piping. Equipped with open sprinklers, water curtain sprinklers, water mist sprinklers, and a fire alarm control system, it can form a corresponding water spray fire extinguishing system. It features a simple structure, easy operation, reliable safety, and convenient installation and maintenance. In case of a fire, the deluge valve opens, and the system's open sprinklers spray water onto the fire source, while simultaneously automatically spraying water throughout the protected area to prevent the fire from spreading and expanding. It is suitable for buildings and sites with a high fire hazard that are prone to icing or require key protection.

A dry alarm valve is used in dry sprinkler fire suppression systems. These systems are typically used in buildings where the ambient temperature is below 4℃. In standby mode, compressed air in the system network seals the fire suppression water on the supply side via the dry alarm valve. When a sprinkler activates, causing a drop in network air pressure to a certain value, the dry alarm valve opens, and pressurized water enters the system network to begin fire suppression.
