Description
(54) ВОЗДУХОВОД(54) AIR DUCT
1one
Изобретение относитс к области вентил ции, а именно к воздуховодам, примен емым в вентил ции дл транспортировки воздуха.The invention relates to the field of ventilation, namely to air ducts used in ventilation for transporting air.
Известен воздуховод, содержащий эластичную обечайку, выполненную в виде отдельных секций, соединенных между собой бандажами, и каркас 1.Known duct containing elastic shell, made in the form of separate sections, interconnected by bandages, and the frame 1.
Однако подобный воздуховод имеет большое аэродинамическое сопротивление при транспортировке воздуха, обусловленное наличием в воздуховоде р да бандажных стыков секций.However, such a duct has a large aerodynamic resistance during the transportation of air, due to the presence in the duct of a number of retaining joints of sections.
Цель изобретени - снижение аэродинамического сопротивлени воздуховода .The purpose of the invention is to reduce the aerodynamic resistance of the duct.
Это достигаетс тем, что каркас воздуховода выполнен в виде эластич ной оболочки,, расположенной внутри обечайки и имеющей на наружной поверхности спиральную трубку, витки которой соединены между собой продольными трубками.This is achieved by the fact that the frame of the duct is made in the form of an elastic shell, located inside the shell and having a spiral tube on the outer surface, the coils of which are interconnected by longitudinal tubes.
На чертеже приведен воздуховод, разрез по продольной оси.The drawing shows the duct, a section along the longitudinal axis.
Воздуховод содержит эластичную обечайку 1, выполненную в виде отделных секций 2, соединенных между собо бандажами 3, и каркас, выполненный в виде эластичной оболочки 4,расположенной внутри обечайки 1 и имеющей на наружной поверхности спиральную трубку 5, витки которой соединены между собой продольными трубками 6. Дл креплени воздуховода на обечайке 1 установлены крюки 7, а дл заполнени спиральной трубки 5 и продольны трубок 6 сжатым воздухом имеетс патрубок 8.The air duct contains an elastic shell 1, made in the form of separate sections 2, connected between themselves 3, and a frame, made in the form of an elastic shell 4, located inside the shell 1 and having a spiral tube 5 on the outer surface, the coils of which are interconnected by longitudinal tubes 6 Hooks 7 are mounted on the shell 1 to secure the duct, and a pipe 8 is provided to fill the spiral tube 5 and longitudinally the tubes 6 with compressed air.
Воздуховод работает следующим образом.The duct works as follows.
Секции 2 обечайки 1 соедин ют между собой бандажами 3 и креп т в нужном месте крюками 7. Затем внутрь обечайки 1 вставл ют эластичную обо- лочку 4 и через патрубок 8 заполн ют трубки 5 и 6 сжатым воздухом, при этом воздуховод принимает форму, близкую к цилиндрической.The sections 2 of the shell 1 are interconnected by bandages 3 and secured at the right place with hooks 7. Then the elastic sheath 4 is inserted into the shell 1 and the tubes 5 and 6 are filled with compressed air through the nozzle 8, and the air duct takes on a shape close to to cylindrical.
Применение воздуховода подобной конструкции позвол ет снизить аэродинамическое сопротивление, что приводит к экономии аэроэнергии,необходимой дл транспортировки воздуха.The use of an air duct of such a construction reduces aerodynamic drag, which leads to savings in the aeroenergy required for transporting air.
