Description
с трубки 5 и 6 приема давлени , перемещение дополнительной тру.бы 3 прекращают и измер ют рассто ние L при помощи линейки 9. Рассто ние L вл етс длиной участка стабилизации потока за местным сопротивлением , которое необходимо учитывать лри установке на основном трубопроводе / расходомера .From the pressure receiving pipe 5 and 6, the displacement of the additional pipe 3 is stopped and the distance L is measured using a ruler 9. The distance L is the length of the flow stabilization section beyond the local resistance, which must be taken into account on the main pipeline / flow meter.

Устройство дл олределени длины участка стабилизации лотока за местным сопротивлением , содержащее основной трубопровод с трубкой приема полного давлени , конец -которой размещен по оси трубопровода, и трубкой -приема статического давлени , размещенной в пристенной области, подключенными к дифманометру, отличающеес тем, что.A device for determining the length of the stabilization section of the tray behind a local resistance, containing a main pipeline with a full pressure pipe, the end of which is located along the axis of the pipeline, and a pipe receiving static pressure located in the near-wall region, connected to a differential pressure meter, different from
с целью повыщени точности олределени места установки расходомеров, оно снабжено дополнительной пр .молинейной трубой, введенной коаксиально на ходовой посадке через сальниковое уплотнение в основной трубопровод за местным сопротивлением, причем на выходе дополнительной трубы укреплен г}1бкий щланг отвода жидкости, а на входе - упом нутые трубки приема полного и статического давлений, при этом рассто ние от отверстий приема давлени каждой из трубок до торца дополнительной трубы превыщает 8 диаметров основного трубопровода.In order to improve the accuracy of the installation location of the flow meters, it is equipped with an additional linear pipe inserted coaxially on the running fit through the gland seal into the main pipeline for local resistance, and at the exit of the additional pipe it is reinforced with a single discharge hose, and Full and static pressure receiving tubes, while the distance from the pressure receiving holes of each of the tubes to the end of the additional pipe exceeds 8 diameters of the main pipeline.
