(54) УСТРОЙСТВО ДЛЯ СПРЯМЛЕНИЯ ПОТОКА(54) DEVICE FOR FLOORING

Изобретение относитс  к измерительной технике и может быть использовано, в частности , в устройствах дл  измерени  расхода капельных жидкостей и газов в расходомерах с сужающим элементом.The invention relates to a measuring technique and can be used, in particular, in devices for measuring the flow rate of dropping liquids and gases in flowmeters with a restricting element.

Известные устройства дл  спр млени  потока, выполненные в виде перфорированного диска с отверсти ми равного диаметра установленного в измерительном трубопроводе круглого сечени  перпендикул рно к нему, способствуют устранению неконцент ричного распределени  скорости потока за диском или спиралеобразного движени  жидкости и обеспечивают более равномерное распределение скорости потока.The known devices for streamlining, made in the form of a perforated disk with holes of equal diameter installed in a circular measuring tube perpendicular to it, help to eliminate the non-concentric distribution of the flow velocity behind the disk or the spiral motion of the fluid and provide a more uniform distribution of the flow velocity.

Однако они не обеспечивают турбулентного распределени  скорости потока за диском , необходимого дл  точного измерени However, they do not provide a turbulent distribution of the flow rate behind the disk, which is necessary for accurate measurement.

Цель изобретени  - уменьшение завихрени  потока и получение за диском турбулентного профил  скоростей контролируемо;ГО потока.The purpose of the invention is to reduce the flow turbulence and obtain a turbulent velocity profile behind the disk in a controlled manner;

: Эта цель достигаетс  тем, что плотност расположени  отверстий в перфорированном : This goal is achieved by the fact that the density of holes in a perforated

диске уменьшаетс  от его центра к периферии , а отношение толщины диска к диаметру отверсти  находитс  в пределах 1-3.the disk is reduced from its center to the periphery, and the ratio of the thickness of the disk to the diameter of the hole is in the range of 1-3.

Устройство обеспечивает точное измерение расхода при наличии короткого пр - ; мого измерительного участка путем созда ни  потока, гидравлически подобного потоку , в котором производилась калибровка прибора.The device provides accurate flow measurement in the presence of a short apr; of the measuring site by creating a flow, hydraulically similar to the flow in which the instrument was calibrated.

При протекании контролируемого потока через устройство он движетс  к центру трубопровода благодар  тому, что отверсти  в перфорированном диске расположены так, что количество их на един1щу площадиWhen a controlled flow through the device flows, it moves to the center of the pipeline due to the fact that the holes in the perforated disk are arranged so that their number is in a single area
