    • A foam expansion tube for a fire fighting nozzle includes a tubular body with a longitudinal axis and a passageway extending there through along the longitudinal axis for directing a foam and water mixture from a fire fighting nozzle. The passageway has a larger diameter than the outlet of the nozzle to provide an expansion tube for the foam/water mixture. The tubular body further includes an inlet end and an outlet end, with the inlet end having an inlet adapted for mounting to the outlet of the fire fighting nozzle for receiving the foam/ water mixture into the passageway and having at least one opening to allow air to be drawn into the passageway for mixing with the foam/water mixture flowing through the passageway. The tube further includes a structure that extends into the passageway wherein the structure separates the foam/water mixture to further enhance the expansion of the foam and water mixture.
    • 用于消防喷嘴的泡沫膨胀管包括管状体,其具有纵向轴线和沿着纵向轴线延伸穿过的通道,用于引导来自消防喷嘴的泡沫和水混合物。 通道的直径大于喷嘴的出口直径,以提供用于泡沫/水混合物的膨胀管。 管状体还包括入口端和出口端,入口端具有入口,该入口适于安装到灭火喷嘴的出口,用于将泡沫/水混合物接收到通道中并且具有至少一个开口以允许空气 被吸入通道中,与流过通道的泡沫/水混合物混合。 该管还包括延伸到通道中的结构,其中该结构分离泡沫/水混合物以进一步增强泡沫和水混合物的膨胀。
