The fire nozzle is an important part of the firefighting system. The selection of the fire nozzle type to be used by the department should depend upon the tactics and performance required. You should decide what you want your nozzle to do before making your decision.<\/p>\n
Nozzles are designed to help put out fires by getting the right amount of water, in the right form, in the right place.<\/p>\n
Nozzles have three main functions:<\/strong><\/p>\n Different Type of nozzles:<\/strong><\/p>\n Its purpose is to produce a solid stream, which provides maximum reach and penetration.<\/p>\n The simplest form of the combination or fire nozzle type, provides flow at a predetermined rate that cannot be altered significantly while in use. However, when the nozzle pressure is varied the flow varies.<\/p>\n\n
\nThe size of the orifice in the outlet of the nozzle controls the flow.<\/li>\n
\nThe nozzle creates a restriction at the end of the waterway, which changes water pressure to velocity. Velocity provides the reach, which is necessary to get the water to where it is needed.<\/li>\n
\nDifferent situations require different methods of applying water or foam. Some situations require the reach and penetration of a straight stream, while others require the heat adsorption capability or radiant heat protection of a wide angle fog spray.<\/li>\n<\/ol>\n\n
