1. one kind comprises the special dry sprinkler systems of the ceiling of sprinkler grid for the protection of storage occupancy;

  • each water jet in wherein said sprinkler grid comprises and has entrance, exports and be arranged on passage therebetween to limit the trigger assembly of the TempNominal of closing assembly described in the water jet main body of the specified K factor of 11 or larger, the closing assembly comprising plug-like component, the support adjacent with the outlet of described water jet main body and to be coupled to described main body and the baffler assembly separated with described outlet, and described dry sprinkler systems comprises;

    Piping network, comprises the stem portion that wet end divides and be connected to wet end to divide, and this stem portion is configured to activate water jet response with at least the first and catches fire;

    AndThe forcing fluid transmission delay cycle, divide from wet end and activate water jet delivering fluids at least the first, this delay period is long enough to make stem portion activate water jet in response to catching fire with at least the second further, this at least the first and at least the second activation water jet definition is enough to the expection sprinkler operational area surrounding and flood fire extinguishing calamityWherein, this system is included in wet end and divides the main water control valve providing controlled isolation between stem portion, and water jet near on water jet far away and at least one hydraulic pressure on this stem portion comprises relative to main water control valve at least one hydraulic pressure,Wherein, the minimum Bind delivery delay period of forcing fluid transmission delay period definition and maximum fluid transmission delay cycle, minimal propagation delay period definition is fed to fluid the time of water jet near at least one hydraulic pressure from control valve, maximum fluid transmission delay period definition is fed to fluid the time of water jet far away at least one hydraulic pressure from control valveWherein, the maximum fluid transmission delay cycle is long enough to the hot activation of permission more than first water jet thus formation responds the maximum sprinkler operational area catching fire and have and surround and flood effect of going out, and minimum Bind delivery delay period is long enough to the hot activation of permission more than second water jet, the minimum sprinkler operational area having and surround and flood effect of going out thus formation response is caught fire, andWherein, minimum sprinkler operational area is defined by the water jet of the critical mass comprising water jet nearest on hydraulic pressure, and the water jet of this critical mass is defined as making water to introduce storage occupancy, the water jet that affect intensity of a fire growth, then make intensity of a fire continued growth and trigger additives amount to be to form expection sprinkler operational area thus to surround and flood the minimum water jet quantity that gesture of putting out a fire grows.
