摘要: A water jet discharge pipe which produces a wide effective spray area and long water reach at low pressure and water volume. Compressed air is injected around the periphery of the pressurized water stream produced through an inner cylindrical member and which is throttled by a nozzle extending into such inner cylindrical member. The injected air prevents reduction of the flow velocity of the water by contact with the inner wall of the cylindrical member. In addition, external air is introduced through air inlets in an outer cylindrical member extending from the inner cylindrical member so as to straighten the air layer accompanying the water jet exiting from the inner cylindrical member and suppress premature dispersal of the water stream prior to ejection from the outer cylindrical member. After such ejection, expansion of the injected air atomizes the water stream to provide large area coverage thereof.

摘要: This invention relates to a fire supervising system and a fire extinguishing target determining method in the water discharging and fire extinguishing operation. The system and method of the present invention is characterized by dividing a fire supervisory region into a matrix pattern to set a pluraity of sections; identifying the section corresponding to a position of a fire from the positional information of the fire starting within the supervisory region which has been output from a fire sensor; and selecting a water discharging target for a water discharging nozzle based on a priority order which has been preliminarily set for the respective sections or selecting the water discharging nozzle in charge, optimum for the fire extinguishing operation which has been set preliminarily for the respective sections.

摘要: A damper for use in controlling the flow rate or direction of a flow of air or fumes flowing out from a room or space or flowing through a ventilation system, including a housing having at least one inlet opening. The housing has a tubular side wall in which are provided a plurality of outlet apertures opened and closed by associated closure members which are adapted to swing to and away from the side wall, preferable inwardly of the housing. The total flow area of the outlet apertures may be extended to a desired degree by increasing the axial length and diameter of the side wall of the housing, whereby the flow resistance and pressure drop across the damper are reduced.
