fire nozzle

Fire nozzles are one of the most widely used firefighting equipment. Fire nozzles can provide a constant flow of water, foam, or a variety of extinguishing agents, or allow firefighters to select the most appropriate flow rate and operating pressure for extinguishing a fire. A fire nozzle is attached to the fire hose to deliver water or fire extinguishing foam to extinguish the fire. Fire extinguishers extinguish a fire by spraying a large volume of extinguishing liquid onto a fire, or more precisely, by spraying very small droplets of water that evaporate quickly, displacing oxygen and suffocating the fire. Therefore, there are different nozzles to achieve different water flows. In certain situations, nozzles can be used to reduce the risk of starting a fire in the first place. Usually these provide a low level of wetting of the area to raise the flash point. Finer nozzles can also be used to increase air humidity to reduce the risk of static build-up in some areas where sparking may present a fire hazard, or to reduce dust levels in an area that may present a fire or explosion hazard. did In certain situations, nozzles are used to protect key assets from the effects of fire. These assets may contain gas reservoirs that may pose a risk of explosion if heated. Alternatively, nozzles may be used to create a “waterway” that provides a safe route out of an area for people trapped in a fire zone. The nozzles required for these applications have relatively high throughput and usually have a more directional spray cone than fire extinguishing nozzles.

Firefighting nozzles are divided into different categories according to the type of extinguishing agent, the required pressure when exiting the nozzle, the required flow rate, and the type of water spraying.

Simple fire nozzle

A simple firefighting nozzle with uniform water spray concentrates the type of spray for extinguishing. This type of nozzle is limited to a spray pattern that varies depending on different manufacturers. This type of nozzle increases the quality of water streams and makes it possible to test hydrants, pumps and other fire protection equipment.

Simple fire hydrants as we know them today emerged from a series of 19th century studies showing that long pipes with smooth interiors produced direct and effective streams of water. In the early 20th century, these nozzles had long handles and handles that allowed firefighters to control the direction of the flow, and today they are a rigid device that attaches to a standard fire hose that provides a grip surface. became.

Simple fire nozzles evolved from something like a general fire hose nozzle to a specialized tool for investigators. Today, these nozzles help fire professionals measure water flow rates, especially when testing fire hydrants or fire pumps. This device enables the measurement of the pressure of the flowing liquid at a point very close to the outlet and provides a baseline measurement against which the nozzle exit flows can be compared. These nozzles have a remarkable discharge coefficient of 0.977 or nearly 98%.

Hozreli nozzle puck

This type of puck nozzle is to be placed in fire fighting boxes and on hose rail reels, which are generally produced in 3/4 inch and 1 inch sizes. The performance of this type of fog nozzle is based on the rotation of the upper shell, after which the water comes out of the nozzle.

Hoseril nozzle puck in its three different modes (jet, spray and combined) is connected to the hose reel of different sizes (maximum opening diameter up to 38 mm) for different fire fighting purposes. The nozzle of the hose reel in jet and spray mode provides the possibility of spraying water in a hollow form. Hosereli fog nozzle in jet and spray modes has different extinguishing features so that it can be controlled and directed by different operators.

Hose reel nozzles in jet and spray type are usually made in 19 mm size. It is also made of ABS polymer. For spraying water as a hollow jet or spray, the nozzle reel should give a jet with a good range (at least 6 meters) and a narrow and wide angle spray. The nozzle reel must also be suitable for other fire extinguishers other than water and must be suitable for connection to a ¾ inch hose. The extinguishing spray pressure in these fog nozzles is up to 10 kg/cm3 and they have an approximate weight of 500 grams, which is ideal for firefighters.

This type of nozzle, which is made of aluminum, is used in industries with high corrosiveness and has a long life, and it changes in three closed modes and two different types of spraying. All metal three-position valve nozzles are manufactured in accordance with BS EN 15182-1:2007 and BS EN 15182-3:2007 A1:2009 standards. These nozzles have a body and a tip made of aluminum, and the tube material is also made of polyamide. This nozzle has the ability to convert the direct flow of water into three different modes of spray, jet and shot. This adjustment of water flow in different modes helps the firefighters to choose sprays suitable for the type of fire in different extinguishing conditions. Its all-metal aluminum body is very light and fire-resistant, and this characteristic of fog nozzles also helps firefighters a lot during the fire extinguishing process. These fire nozzles are suitable for general industrial, commercial applications. Also, these nozzles are ideal for fire departments, professional industry services, as well as refineries, armed forces, airports, ships, oil platforms and heavy industries.

Professional POK gun fire extinguisher nozzle

Poke nozzle is a piece of firefighting equipment. A fog nozzle mechanically breaks water into tiny droplets and disperses them like a fog. Automatic or manual adjustment of the nozzle fog creates spray mode characteristics that vary in length and width. Trained firefighters use each spray pattern of fog nozzles in different situations.

POK gun fire nozzle is a fully compatible nozzle for fires in confined spaces.

This aluminum alloy nozzle has an ultra-compact pressure regulation system as well as a flow selection system with an indicator operating handle. Its diffuser head with aluminum alloy cut teeth offers the possibility to adjust the jet in three positions (direct jet, attack jet, wide spray jet).

This nozzle is fully adapted to the Pulsing technique, allowing firefighters to perform the ceiling test with very low recoil and fine droplet quality, allowing for highly efficient work on urban fires.

The Pok fire nozzle is capable of achieving the same flow rate as conventional nozzles with a lighter weight and smaller size. These nozzles are available in different types. This fog nozzle is among the nozzles that provide the possibility of extinguishing fires caused by electrical fires. This version is equipped with a safety device that prevents accidental passage of the nozzle holder through a full jet. To unlock the full jet, the user must use a trigger under the nozzle.

Firefighters usually use nozzle pucks with hand hoses. Water sprays through these hoses at a rate of 60 to 180 gallons (227 to 681 liters) per minute. The force of the water hitting the special dispersing element inside the nozzle turns the droplets into vapor-like particles. The vapor produced resembles a wet mist and covers a larger surface area than a stream of water.

An automatic nozzle puck generally adjusts the length and width of the material being sprayed based on the water pressure. Manual nozzles have a handle that firefighters use to adjust the spray pattern regardless of water pressure. The nozzle may be set to emit a straight stream of water, a narrow-angle cone, or a wide-angle cone. Narrow-angle fog may also contain a central stream of water. Wide angle fog not only covers more area but also acts as a shield to protect firefighters.

ROSENBAVER professional turbo gun nozzle puck
These advanced nozzles are a combination of high pressure technology and O-stream nozzles that enable water atomization. This method of atomization causes the small droplets to completely vaporize, thereby depriving the fire of maximum heat energy. In practice, this leads to the optimal effect of the quenching agent. Due to the special style of these puck nozzles, the reaction force is directed directly to the rear. This work seems very natural due to the high pressure of water spraying in these puck nozzles. The way to use these puck nozzles is that the front hand is free to guide the nozzle or adjust the flow pattern. Using the puck nozzle trigger, water can be released in both small and very fine bursts. The nozzle impact guard can be removed to securely lock the foam tube (option). In these nozzles, side air inlets, flow separators and baffle plate ensure excellent foam quality. The flow pattern can be adjusted very quickly to the operating conditions by rotating the O-stream nozzles. Only a quarter of the screw is between the latch and the water flow. Therefore, the entire adjustment range can be used without the need to change the knob. The flow patterns in these nozzles are full jet, small jet spray 30 degrees, wide jet spray 60 degrees and water flow 120 degrees.
