An extinguishing fluid nozzle system (1, 100, 200), for stationary fire extinguishing systems, with an extinguishing fluid nozzle having a main body (3, 104, 204) which has an inlet opening (23, 123, 223) and can be fixed in fluid-conducting relationship to an extinguishing fluid line, a nozzle head (5, 106, 206) which has one or more outlet openings (25, 125, 225) connected in fluid-conducting relationship to the inlet opening for the discharge of the extinguishing fluid, and an aperture (7, 107, 207) having an aperture ring (15, 115, 215) for flow limitation, arranged in the fluid path between the inlet opening and the one or more outlet openings. The aperture has a grip portion (17, 117, 217) which is fixedly connected to the aperture ring and which extends outwardly from the aperture ring and which in the fitted condition of the aperture extends outside the extinguishing fluid nozzle.

An improved nozzle for use with a fire hose having an infra-red temperature sensor that is aligned with an output of the nozzle. The sensor will detect the infrared energy produced by a fire hot spot and provide a visual indication of the energy on a display. The temperature sensor operates a thermometer and is placed in the center of the discharge nozzle allowing water to pass around the sensor. A laser is positioned next to the sensor on the outlet of the nozzle to project a high intensity visible light toward the area that the IR sensor is directed.

One or more techniques and/or systems are disclosed for a dual shutoff nozzle that can mitigate a user positioning a bale handle of the nozzle in an intermediate position to achieve fog flow through the nozzle. A nozzle may be devised that allows the bale to be disposed in a fully closed position, and/or disposed in a fully open position, and to switch between a fog spray and a straight tip flow. The nozzle may comprise a first flow control element, and a shutoff component that controls the first control element. The nozzle can comprise a second flow control element that controls flow between a straight nozzle outlet and a fog pattern outlet; and the second flow control element can be controlled by a pattern sleeve using a rotation motion.

An emitter system capable of discharging an atomized liquid-gas stream or a liquid stream which atomizes into a spray has a source of pressurized gas and one or more sources of pressurized liquids. Flow of gas and liquid to an emitter is controlled by valves, and the emitter can be used to discharge either the atomized liquid-gas stream or the liquid stream. The emitter system may be used for fire suppression.

A new firefighting nozzle has a series of moveable vanes that extend inwardly from a peripheral wall of a base. The inner side of the vanes extends between and of the diameter of the central channel. The vanes rotate between a linear position, in which the vanes are generally parallel to the direction of the channel, and a vortex position, in which the vanes are significantly angled with respect to the direction of the channel. In the linear position, smooth bore linear flow is produced. In the vortex position, any of a range of fog patterns are produced. An externally mounted controller connects to the vanes and enables a firefighter to change the shape of the nozzle's spray without interrupting the flow. The controller and base have a series of pins that slide in a spiral groove and cause the shaper to move axially with respect to the base when the shaper is rotated about the base. Radial stems that ride in a circumferential slot translate that axial movement into rotation of the vanes.

A spray system comprising a nozzle including an inlet body and an outlet body. The inlet body has an inlet surface that defines an inlet fluid channel that extends about an inlet flow axis through the inlet body from an inlet opening to a chamber opening. The outlet body has an outlet surface and a chamber surface. The outlet surface defines at least a portion of an outlet chamber and an in outlet fluid channel. The outlet chamber extends about an outlet flow axis from the chamber surface toward the outlet fluid channel. The outlet fluid channel extends about the outlet flow axis from an outlet opening toward the outlet chamber. The inlet fluid channel of the inlet body is in fluid communication with the outlet chamber of the outlet body via the chamber opening, and the inlet flow axis is spaced from the outlet flow axis.

Wildfire water-supply hose having a QD nozzle with an outer sleeve adapted to engage a firefighter's backpack water bladder's QD connector. The combination male QD nozzle/female QD system permits rapid and easier bottom-up filling of the bladders without dismounting the tank from the firefighter's back, by inserting the QD nozzle into the female QD fitting on the bottom of the backpack bladder. The QD nozzle tip is long enough to open the internal spring-biased shut-off valve in the female QD connector when inserted. Upon opening the supply line valve, water flows into the backpack bladder until full. The supply valve is closed and the QD nozzle is withdrawn from the bladder female QD connector. Rotation of the QD nozzle outer sleeve controls water flow from stream, to spray to mist. The QD nozzle is also used with other types of nozzles on dual fittings having 3-way valves, e.g., fog nozzles.
