Abstract
Изобретение относится к области струйной техники, преимущественно к пароводяным струйным аппаратам, используемым в системах отопления и подачи горячей воды. Пароводяной струйный аппарат содержит паровое сопло с входным сужающимся и выходным расширяющимся участками, приемную камеру для подвода жидкой среды и камеру смешения. Выходной участок парового сопла образует с входным участком камеры смешения сужающееся по ходу движения жидкой среды сопло для ее подвода в камеру смешения. Входной участок камеры смешения выполнен сужающимся и образован конической поверхностью, а выходной участок камеры смешения выполнен цилиндрическим. Отношение площади выходного сечения парового сопла (F) к площади его наименьшего проходного сечения (F) составляет от 2,98 до 4,99. Отношение площади выходного сечения сопла для подвода жидкой среды (F) в перпендикулярном по отношению к конической поверхности камеры смешения направлении к площади поперечного сечения цилиндрического участка камеры смешения (F) составляет от 3,71 до 33,8. Отношение площади наименьшего проходного сечения парового сопла (F) к площади поперечного сечения цилиндрического участка камеры смешения (F) составляет от 0,51 до 4,63 и отношение длины цилиндрического участка камеры смешения к диаметру этого участка камеры смешения составляет от 3 до 5. В результате достигается увеличение устойчивости работы струйного аппарата и расширение диапазона регулирования режима работы струйного аппарата.The invention relates to the field of inkjet technology, mainly to steam-water jet devices used in heating and hot water. Steam-water jet apparatus contains a steam nozzle with inlet tapering and outlet expanding sections, a receiving chamber for supplying a liquid medium and a mixing chamber. The output section of the steam nozzle forms with the inlet section of the mixing chamber a tapering nozzle in the direction of movement of the liquid medium for supplying it to the mixing chamber. The entrance section of the mixing chamber is made tapering and is formed by a conical surface, and the output section of the mixing chamber is cylindrical. The ratio of the area of the output section of the steam nozzle (F) to the area of its smallest flow area (F) is from 2.98 to 4.99. The ratio of the area of the output section of the nozzle for supplying a liquid medium (F) in a direction perpendicular to the conical surface of the mixing chamber to the cross-sectional area of the cylindrical section of the mixing chamber (F) ranges from 3.71 to 33.8. The ratio of the smallest flow area of the steam nozzle (F) to the cross-sectional area of the cylindrical section of the mixing chamber (F) is from 0.51 to 4.63 and the ratio of the length of the cylindrical section of the mixing chamber to the diameter of this section of the mixing chamber is from 3 to 5. the result is an increase in the stability of the jet apparatus and the expansion of the range of regulation of the mode of operation of the jet apparatus.
