Abstract
Изобретение относитс к противопожарной технике и может быть использовано в устройствах дл тушени и локализации пожаров распыленными огнегас щими жидкост ми. Цель - повышение эффективности работы за счет более тонкого распылени жидкости. Дл этого ороситель снабжен полым отражателем, соосно охватывающим часть винтового распылител по всей его длине без зазора. В результате удара струй об отражатель происходит интенсивный распад пленки на цилиндрические струи и возбуждение в них поперечных колебаний сравнительно высокой частоты. Силы аэродинамического сопротивлени среды и высокие поперечные скорости турбулентных потоков жидкости в стру х увеличивают амплитуду этих колебаний и разрушают струи на отдельные капли. 2 ил.The invention relates to fire fighting equipment and can be used in devices for extinguishing and localizing fires with sprayed fire extinguishing liquids. The goal is to increase work efficiency by thinning the liquid. For this, the sprinkler is provided with a hollow reflector, coaxially covering a part of the screw dispenser along its entire length without a gap. As a result of the impact of the jets on the reflector, there is an intensive disintegration of the film into cylindrical jets and the excitation of transverse oscillations of relatively high frequency in them. The aerodynamic drag forces of the medium and the high transverse velocities of the turbulent fluid flows in the jets increase the amplitude of these vibrations and destroy the jets into separate droplets. 2 Il.
Description
Изобретение относитс к противопожарной .технике, а именно к устройствам дл тушени и локализации пожаров распыленными огнегас ш,ими жидкост ми.FIELD OF THE INVENTION The invention relates to fire fighting equipment, namely, devices for extinguishing and localizing fires by spraying fire gases and their liquids.
Целью изобретени вл етс повышение эффективности работы за счет более тонкого распылени жидкости.The aim of the invention is to increase the efficiency of operation due to the finer atomization of the liquid.
На фиг. 1 схематично изображен предлагаемый ороситель; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 schematically depicts the irrigator being proposed; in fig. 2 shows section A-A in FIG. one.
Ороситель содержит корпус 1, сообщенный с источником подачи жидкости (не показано ) и установленный соосно корпусу 1 винтовой распылитель 2. Кроме того, ороситель снабжен п олым отражателем 3, соосно охватывающим часть винтового распылител 2 по всей его длине без зазора. Угол а охвата распылител 2 отражателем 3 выбирают в пределах О-330° в зависимости от величин давлени к требуемого расхода жидкости , а также степени ее распылени .The sprinkler includes a housing 1 communicated with a fluid supply source (not shown) and mounted with a screw gun 2 coaxially with the housing 1. In addition, the sprinkler is provided with a full reflector 3 coaxially covering part of the screw gun 2 along its entire length without a gap. The angle of coverage of the atomizer 2 with the reflector 3 is chosen within the range of O-330 °, depending on the pressure values to the required fluid flow rate, as well as the degree of its dispersion.
Ороситель работает следующим образом .Sprinkler works as follows.
Поток огнетушащей жидкости, вытека с большой начальной скоростью (30-50 м/ /с) из сопла корпуса 1 оросител , попадает во внутренний сужающийс канал винтового распылител 2. Здесь от потока за счет сужени канала винтовыми гран ми отсекаетс пленка жидкости. За счет удара пленки о скошенные грани винтовой спирали распылител 2 она разрушаетс на отдельные струи. Причем струи жидкости в закрытой части спирали удар ютс в отражат&пь 3 и возвращаютс на грани винтовой спирали , по которым вывод тс из закрытой иас- ти наружу. На открытой части спирали происходит соударение струй, сформированных открытой частью спирали, со стру ми, выведенными из закрытой части спирали.The fire extinguishing fluid stream, flowing out at a high initial velocity (30-50 m / s) from the nozzle of the irrigator body 1, enters the inner constricted channel of the screw nozzle 2. Here, a liquid film is cut off from the flow due to constriction of the channel. Due to the impact of the film on the beveled edges of the spiral helix of the atomizer 2, it breaks down into separate jets. Moreover, the liquid jets in the closed part of the helix strike the reflect & p 3 and return to the verge of the spiral helix, which are led out of the closed or the air outside. In the open part of the helix, the jets formed by the open part of the helix collide with the streams removed from the closed part of the helix.
Больщой запас кинетической энергии струй жидкости позвол ет за счет удара струй о скошенные торцы винтовых граней и последующее их соударение сформировать в воздушной среде факел диспергированной жидкости с диаметром капель существенно меньшим.The large kinetic energy reserve of the liquid jets allows, due to the impact of the jets on the beveled ends of the helical faces and their subsequent collision, to form in the air medium a torch of dispersed liquid with a droplet diameter much smaller.
