Early Suppression and Quick Response Nozzles
In the system of quick response and early suppression nozzles, the selection of nozzles is currently being promoted in my country and is mainly used in common applications such as elevated warehouses and large warehousing and logistics warehouses. Places where closed sprinklers are ineffective. The sprinkler head is more sensitive than ordinary sprinkler heads. The heat-sensitive element can respond quickly and can operate when the fire is weak. The amount of water ejected by the nozzle is also larger than that of ordinary nozzles, and can reach the fire point directly. The nozzle sprays a large amount of water under high pressure (the working pressure at the nozzle is not less than . This way the fire can be suppressed in its early stages. Another feature of the sprinkler head is that while the sprinkler head extinguishes the fire on the upper part of the shelf, there is a powerful water column in the center of the sprinkler head, which can pass through the shelf and extinguish the fire at the bottom of the shelf below the sprinkler head. Our country stipulates that the value of the maximum stacking height of goods in warehouses that adopts rapid response and early suppression sprinklers is conservative compared with the American "Installation Standard for Automatic Sprinkler Systems" (Annual Edition) and the American Factory Joint Insurance System Standard. The nozzle flow coefficient in the characteristic formula of the nozzle produced according to the American standard, from the metric system to the minimum working pressure of the metric nozzle, is...
