摘要： A sprinkler head connected with a fire extinguishing piping maintains a valve body in a closed state so as to contain compressed fire extinguishing water filled in a fire extinguishing piping when there is no fire, but opens and operates the valve body so as to discharge the compressed and supplied fire extinguishing water at the time of a fire. The fire extinguishing water is contained by closing the gap between the valve body and the peripheral part of the valve body by a sealing member mounted in the valve body, prepared by coating a rubber base material with a fluorine contained resin coating material. The rubber base material of the sealing member can have a round, oval, U-shaped, Y-shaped, or X-shaped cross-sectional shape. The rubber base material can be made from a fluorine rubber or a silicon rubber. The present invention is to utilize both advantages of the anti-corrosion property and the weathering resistance of a fluorine resin and the elasticity of a rubber, to obtain the sealing property with respect to the fire extinguishing water with a smaller load, and to prevent the malfunction of the sprinkler head caused by alteration or adhesion.

摘要： The present invention is to discharge the fire extinguishing water by accurately opening the valve, using a shape-memory alloy at a predetermined temperature in a fire. When a shape-memory alloy in a first heat sensitive operation part is heated to a predetermined memory restoring temperature, a pilot valve is operated by the restoring force thereof so that a spool valve can be in a state capable of being opened by an actuator. When a second heat sensitive operation part reaches a predetermined water discharge starting temperature higher than the memory restoring temperature, a fusible alloy provided inside is thermally decomposed so that the first heat sensitive operation part maintained in the closed state is released so as to discharge the fire extinguishing water. When the temperature becomes lower than the memory restoring temperature by the fire extinguishment by the water discharge, a restoring spring deforms the shape-memory alloy into the initial shape so as to drive the valve mechanism into the closed state for stopping the water discharge. Accordingly, since the start of the water discharge can be controlled by the water discharge starting temperature having less fluctuation with respect to the memory restoring temperature, the water can be discharged further accurately. Moreover, since the memory restoring temperature needs not be set accurately, the production efficiency of the sprinkler head can be improved to facilitate the mass productivity.
摘要翻译： 本发明是通过在火灾中的规定温度下使用形状记忆合金来精确地打开阀来排出灭火水。 当第一热敏操作部件中的形状记忆合金被加热到预定的存储器恢复温度时，先导阀通过其恢复力来操作，使得滑阀可以处于能够被致动器打开的状态。 当第二热敏操作部件达到高于存储器恢复温度的预定的排水开始温度时，设置在内部的可熔合金被热分解，使得保持在关闭状态的第一热敏操作部件被释放以排出火 灭火水 当通过排水通过灭火使温度变得低于存储器恢复温度时，恢复弹簧将形状记忆合金变形为初始形状，以便将阀机构驱动到关闭状态以停止排水。 因此，由于可以通过相对于存储器恢复温度具有较小波动的排水开始温度来控制排水开始，因此能够进一步精确地排出水。 此外，由于不需要准确地设定存储器恢复温度，因此可以提高喷头的生产效率，以便于批量生产。

摘要： A double-nozzle deluge gun has a pair of nozzles arranged side by side rotatably on a rotatable table and an inter-nozzle control unit for adjusting the inter-nozzle angle measured between two lines obtained by projecting the radiation center lines of the nozzles onto a horizontal plane. Each nozzle has a deflector which is positioned in front of the nozzle during the very short range mode. Each deflector has a side cover which prevents water having passed through the deflector from excessively spreading sideways. The inter-nozzle angle and the water pressure are adjusted in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern in any range. Thus, the double-nozzle deluge gun can be controlled in accordance with desired water-reaching ranges, so as to achieve an optimal watering pattern having an appropriate width in any range.
