摘要： The present invention discloses a device for testing control of polymorphic foam on flowing fire, comprising a test bench, a combustible liquid injecting mechanism and a polymorphic foam spraying mechanism. The combustible liquid injecting mechanism and the polymorphic foam spraying mechanism are relatively arranged on the test bench. The combustible liquid injecting mechanism can spray combustible liquid to the test bench. The polymorphic foam spraying mechanism can spray polymorphic foam to the test bench, and the spraying direction of the polymorphic foam is relative to the spraying direction of the combustible liquid. The present invention can be used for testing and observing cut-off and control effects of polymorphic foam on combustible liquid flowing fire.

摘要： A high pressure water/foam nozzle assembly is disclosed which includes a barrel having a first end, a second end and a collar positioned about the first end. The assembly also includes first, second and third nozzles positioned in the barrel. Each of the nozzles can emit a different spray pattern. A selection mechanism is positioned adjacent to the second end of the barrel and is rotatable between three positions which align with the three nozzles. The assembly further includes a control mechanism secured to the second end of the selection mechanism which controls the flow of water and/or foam through one of the three nozzles. A handle and trigger are connected to the control mechanism. The trigger activates the flow of water and/or foam through one of the three nozzles. An infrared camera is removably secured to the control mechanism and is used to detect hot spots in a fire.

摘要： A pneumatically powered foam sprayer is provided. The foam sprayer includes a spray hose having a spray nozzle, a trigger assembly proximate the spray nozzle, and a pressure-actuated valve responsive to the trigger assembly. An air conduit extends between the pressure-actuated valve and an opening in the trigger assembly. Obstructing the opening with a hand, a finger or a thumb creates a change of air pressure within the air conduit and actuates the pressure-actuated valve to selectively allow the supply of foam into the spray hose. The air conduit may extends longitudinally through an interior portion of the spray hose, or along an exterior portion of the spray hose, and can include a laminar, chemical-resistant outer surface. An internal pump is powered by compressed air through the pressure-actuated valve, and the spray nozzle remains open both during and between uses to prevent the accumulation of pressurized foam within the spray hose.

摘要： A nozzle assembly for encapsulating a gaseous solution in bubbles comprises a discharge tube having a diffuser and a foam solution spray nozzle mounted therein. The discharge tube has upstream and downstream ends. The discharge tube has a front face at the upstream end with a first opening configured to be joined to a gas supply line that provides a gaseous solution and a second opening configured to receive a non-expanded foam solution. The downstream end of the discharge tube is open. A chamber is formed within the discharge tube to receive the gaseous solution at the upstream end and release the gaseous solution through the diffuser into the discharge tube towards the downstream end.

摘要： 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.

摘要： A self-powered foam (e.g. compressed-air foam (CAF)) distributor has a rotor mechanism with impingement surfaces against which foam impinges to rotate the rotor. The rotor is mounted on an inlet shaft geared to an output shaft. A rotary outlet is mounted to the output shaft so that foam entering the distributor rotates the rotary outlet, which in turn projects foam around in a circular sweep. The rotary outlet can rotate over a full 360 degrees, providing superior coverage for a large floor space, such as in hangars or warehouses, with less water and concentrate than in unfoamed conventional systems. Having a compact vertical profile this versatile distributor can be installed in a floor trench of a hangar or on a wall or ceiling. Since all rotational energy is harnessed from the pressure of the foam itself, no external energy source is required to power the distributor.
摘要翻译： 自动动力泡沫（例如压缩空气泡沫（CAF））分配器具有转子机构，其具有冲击表面，泡沫冲击该表面以使转子旋转。 转子安装在与输出轴相连的入口轴上。 旋转出口安装到输出轴，使得进入分配器的泡沫旋转旋转出口，旋转出口依次以圆形扫掠投射泡沫。 旋转出口可以旋转360度，为较大的地面空间提供卓越的覆盖，例如在飞机库或仓库中，比未发泡的传统系统更少的水和浓缩物。 具有紧凑的垂直轮廓，这种多功能分配器可以安装在机库的底板沟槽或墙壁或天花板上。 由于所有旋转能量都来自于泡沫本身的压力，所以不需要外部能量来为分配器供电。
