Abstract
Изобретение относитс к гидромеханике, в частности к трубопроводам дл транспортировани жидких и газообразных сред, и может быть использовано дл трубопроводов, работающих в режиме турбулентного течени . Целью изобретени вл етс повышение эффективности устройства и расширение его функциональных возможностей путем обеспечени заданных радиальных габаритов. Указанна цель достигаетс тем, что в устройстве, содержащем по крайней мере один диффузорный и установленный последовательно с ним выравнивающий участки, последний выполнен в виде хоней- комба-детурбулизатора, установленного на рассто нии АI от выхода диффузорного участка с чейкой размером а. За диффузор- ным участком установлен конфузор с криволинейной поверхностью, причем А1 < h , а = 0,1 - 0,5di. h = 1-5, где h - характерный размер турбулизатоpa; di - начальный диаметр диффузорного участка. 1 ил.(ЛThe invention relates to hydromechanics, in particular to pipelines for transporting liquid and gaseous media, and can be used for pipelines operating in a turbulent flow regime. The aim of the invention is to increase the efficiency of the device and expand its functionality by providing predetermined radial dimensions. This goal is achieved by the fact that in the device containing at least one diffuser and leveling sections installed in series with it, the latter is made in the form of a hone-deturbulator installed at a distance of AI from the outlet of the diffuser section with a cell of size a. A confuser with a curved surface is installed behind the diffuser section, with A1 < h, a = 0.1 - 0.5 di. h = 1-5, where h is the characteristic size of the turbulizer; di is the initial diameter of the diffuser section. 1 il.

Description
Изобретение относитс к транспортированию жидких и газообразных сред и может быть использовано дл трубопроводов, работающих в режиме турбулентного течени .The invention relates to the transport of liquid and gaseous media and can be used for pipelines operating in turbulent flow mode.
Известен способ однородного распределени скоростей по сечению трубы.There is a known method of uniform distribution of velocities over a pipe section.
Согласно указанному способу в трубопроводе устанавливают неоднородный резистивный элемент дл получени однородного профил скоростей потока через ,трубопровод. Его сопротивление измен ют так, чтобы обеспечить равномерно распределение скоростей по сечению сердечника .According to this method, a non-uniform resistive element is installed in the pipeline to obtain a uniform flow velocity profile through the pipeline. Its resistance is varied so as to ensure uniform velocity distribution over the cross section of the core.
К недостаткам данного способа относитс повышенна трудоемкость и сложность , значительное гидравлическое сопротивление неоднородного резистивного элемента в целом, что резко снижает эффективность способа дл трубопроводов, работающих в режиме турбулентного течени .The disadvantages of this method include the increased complexity and complexity, the considerable hydraulic resistance of the non-uniform resistive element as a whole, which drastically reduces the efficiency of the method for pipelines operating in turbulent flow mode.
Известен способ иэменени (уменьшени ) гидравлического сопротивлени магистрали трубопровода согласно которому, основанному на изменении геометрии проточнбй части магистрали за счет механической обработки последней, в магистраль вставл ют элемент типа сопла Вентури и последовательно укорачивают (удлин ют) его выходную часть дл уменьшени (увеличени ) длины выходного диффузора и его диаметра.The known method of changing (decreasing) the hydraulic resistance of the pipeline main line, according to which, based on the change in the geometry of the flow section of the line due to machining of the latter, a Venturi nozzle type element is inserted into the line and its output part is shortened (extended) to reduce output diffuser and its diameter.
