    • A preaction dry pipe alarm valve (1) is provided for a sprinkler pipework (24) and sprinklers with a fire detection and extinguishing control panel (26). A water supply (38 and an air feed (37) are selectively in communication with the sprinkler pipework. A pilot control chamber (19) of the preaction dry pipe alarm valve (1) is depressurized in case of a fault message from the fire detection and extinguishing control panel (26). When the pilot control chamber (19) is depressurized and, in the case of a decreasing pressure in the sprinkler pipework (24), a quick opener (40) opens the valve head (2) of the preaction dry pipe alarm valve (1), so that extinguishing water can flow into the dry pipework (24). The system allows very short flooding times for the sprinkler pipework with no additional rapid vents installed in the pipework.
    • 为喷水管道(24)提供预干燥管道报警阀(1),并配有灭火控制面板(26)。 一个供水管道(38和一个空气供给装置)选择性地与喷淋管道连通,预防干管报警阀门(1)的先导控制室(19)在发生火灾检测的故障信息时被减压 和灭火控制面板(26),当先导控制室(19)减压时,在喷淋管道(24)的压力降低的情况下,快开装置(40)打开阀头(2) 预干燥管道报警阀(1),使灭火水可以流入干燥管道(24),系统允许喷水管道的洪水时间很短,管道中没有安装快速通风口。

    • A preaction dry pipe alarm valve (1) for a sprinkler pipework (24) with sprinklers with a fire detection and extinguishing control panel (26), a water supply (38), valves, the air feed (37), wherein the pilot control chamber (19) of the preaction dry pipe alarm valve (1) is depressurized in case of a fault message from the fire detection and extinguishing control panel (26), wherein a quick opener (40) which is in connection with the preaction dry pipe alarm valve (1), when the pilot control chamber (19) is depressurized and, in the case of a decreasing pressure in the sprinkler pipework (24), opens the valve head (2) of the preaction dry pipe alarm valve (1), so that extinguishing water can flow into the dry pipework (24). The system requires no additional rapid vents need to be installed in the pipework, which allows achieving very short flooding times for the sprinkler pipework.
    • 一种用于具有喷水灭火和灭火控制面板(26)的洒水管道(24)的预干燥管道报警阀(1),供水装置(38),阀门,空气供给装置(37),其中先导控制 在火灾探测和熄灭控制面板(26)发生故障信息的情况下,预干燥管道报警阀(1)的腔室(19)被减压,其中与预干燥管道相连的快速开启器(40) 报警阀(1),当先导控制室(19)减压时,在喷水管道(24)压力降低的情况下,打开预干燥管道报警阀(1)的阀头(2) ,使得灭火水可以流入干燥管道(24)。 该系统不需要在管道中安装另外的快速通风口,这样可以实现洒水管道的非常短的淹水时间。
