Abstract
Изобретение относится к пожарной технике, а именно к ручным стволам, предназначенным для тушения пожаров, и направлено на обеспечение возможности подачи сплошной или распыленной с изменяющим углом факела струи воды или создания водяной завесы с максимальными значениями дальности и расхода огнетушащего вещества при минимизации гидравлических потерь при тушении пожара. Ствол пожарный ручной комбинированный (см. фиг. 1) включает корпус с переходником и соединительной головкой для пожарного рукава, устройство перекрывное, устройство регулирования поступающего в ствол потока раствора, устройство формирования струи, включающее насадок с дефлектором, в котором согласно изобретению внутренняя поверхность дефлектора насадка выполнена в виде кубической параболы, причем текущий радиус криволинейной части дефлектора определяется по зависимостигде rтекущий радиус криволинейной части дефлектора, мм; l- текущая длина криволинейной части дефлектора, мм; bтолщина дефлектора, мм; c -параметр, зависящий от объемной подачи ствола, и для ручных стволов находится в диапазоне 1000-2000 мм.The invention relates to fire equipment, in particular to handheld barrels designed to extinguish fires, and is aimed at ensuring the possibility of supplying a jet of water, continuous or sprayed with a changing torch angle or creating a water curtain with maximum values of the fire extinguishing agent while minimizing hydraulic losses during extinguishing the fire. A handheld fire barrel combined (see Fig. 1) includes a housing with an adapter and a connection head for a fire hose, a shut-off device, a device for regulating the flow of the solution entering the barrel, a jet forming device including nozzles with a deflector, in which, according to the invention, the inner surface of the deflector made in the form of a cubic parabola, the current radius of the curvilinear part of the deflector being determined according to the current radius of the curvilinear part of the deflector, mm; l is the current length of the curved part of the deflector, mm; b deflector thickness, mm; The c-parameter, depending on the volumetric supply of the barrel, and for manual barrels is in the range of 1000-2000 mm.
