Изобретение относитс к области вентил ции и может быть использовано дл подачи воздушного факела, смешанного из двух струй, поступающих из воздуховода приточной вентил ции и окружаюш,его пространства помеш;ени .The invention relates to the field of ventilation and can be used to supply an air plume mixed from two jets coming from the duct of the intake ventilation and the surrounding air space.

Известны воздухораспределители, содержащие входной патрубок с насадком, размещенным в корпусе с образованием кольцевой щели, и дисковый отражатель, установленный соосно корпусу с возможностью осевого перемещени .Air distributors are known that contain an inlet with a nozzle placed in the housing with the formation of an annular gap, and a disk reflector mounted coaxially with the housing with the possibility of axial movement.

Однако при эксплуатации этих воздухораспределителей создаетс аэродинамический шум в помещении, а также в них не обеспечиваетс регулирование подаваемого в помещение воздуха и, следовательно, не обеспечиваетс повышение затухани скорости воздушного факела и выравнивание его температуры.However, during operation of these air distributors, aerodynamic noise is created in the room, and they do not control the air supplied to the room and, therefore, do not increase the attenuation of the velocity of the air torch and equalize its temperature.

Целью насто щего изобретени вл етс снижение аэродинамического щума и повышение надежности.The aim of the present invention is to reduce aerodynamic noise and increase reliability.

Указанна цель достигаетс тем, что в патрубке вдоль его оси закреплен резьбовой шток, насадок выполнен конфузорньш, корпус - в виде однополостного гиперболоида , а отражатель имеет коническую поверхность , плавно сопр женную с его диском , причем корпус и отражатель закреплены на резьбовом штоке.This goal is achieved by the fact that a threaded rod is fixed in the nozzle along its axis, the nozzles are confused, the casing is in the form of a single-cavity hyperboloid, and the reflector has a conical surface that smoothly mates with its disk, with the casing and the reflector attached to the threaded rod.

На чертеже изображен воздухораспределитель , продольный разрез.The drawing shows the air distributor, a longitudinal section.

Воздухораспределитель содержит входной патрубок 1 с насадком 2, размещенным в корпусе 3 с образованием кольцевой щели 4, и дисковый отражатель, установленный соосно корпусу 3 с возможностью осевого перемещени . В патрубке 1 вдоль его оси закреплен резьбовой шток 5, насадок 2 выполнен конфузорным, корпус 3 - в виде однополостного гиперболоида, а отражатель имеет коническую поверхность 6, плавно сопр женную с его диском 7, причем корпус 3 и отражатель закреплены на резьбовом штоке 5.The air distributor contains an inlet 1 with a nozzle 2 placed in the housing 3 with the formation of an annular gap 4, and a disk reflector mounted coaxially with the housing 3 with the possibility of axial movement. A threaded rod 5 is fixed in nozzle 1 along its axis, nozzles 2 are made confused, body 3 is in the form of a single-cavity hyperboloid, and the reflector has a conical surface 6 that smoothly mates with its disk 7, and case 3 and the reflector are fixed on the threaded rod 5.

Воздухораспределитель работает следующим образом.The air distributor operates as follows.

Claims

The intake air through the inlet nozzle 1 enters the nozzle 2, from which it flows into the cavity of the housing 3 at high speed, creating a vacuum in its upper part, due to which air from the room is sucked through the annular slot 4. The mixture of external and internal air, which is formed in the cavity of the housing 3, flows into the room through a slot formed by the lower part of the housing 3 and the conical surface 6 of the reflector. The implementation of the body in the form of a single-cavity hyperboloid, as well as the performance of the reflector with a conical surface 6, smoothly mated with its disk 7, made it possible to reduce the level of aerodynamic noise. In order to control the amount of air drawn from the room, as well as the amount of air displaced from the housing to the room, the housing 3 and the reflector are fixed on the threaded brush 5. The technical and economic efficiency of using the invention to reduce the level of aerodynamic noise, increase the flow rate of the inlet air with internal air, and attenuation of the mixed air velocity. 20 5 10 Claims of the invention: An air distributor comprising an inlet with a nozzle placed in a housing with the formation of an annular gap and a disk reflector mounted coaxially with the axially displaceable body, characterized in that, in order to reduce aerodynamic noise and increase reliability, in the nozzle along its axis is fixed to a threaded rod, the nozzles are made confused, the casing is in the form of a single-cavity hyperboloid, and the reflector has a conical surface smoothly mated with its disc, with the casing and reflecting The body is fixed on a screw.
