Изобретение относитс к измерению объема, расхода или уровн жидкости , в частности к испытани м на герметичность напорных трубопроводов .The invention relates to the measurement of volume, flow or level of a liquid, in particular to leak tests of pressure pipelines.
Известен акустический способ обнаружени протечек жидкости или газа в напорных трубопроводах, заключающийс в том, что измер ют.в двух точках трубопровода уровень шума, преобразуют его в электрические СИР. налы, сравнивают их ЪёШчинЫг а в одной из точек измер ют параметры, определ ющие величину и характер шума , создаваемого проникающей по трубопроводу средой при целом трубопроводе 1 .A known acoustic method for detecting leakage of liquid or gas in pressure pipelines, which consists in measuring the level of noise at two points in the pipeline, converting it into electrical SIR. They compare their values, and in one of the points measure the parameters that determine the magnitude and nature of the noise created by the medium penetrating through the pipeline in the case of the whole pipeline 1.
Недостатком известного способа вл етс невысока чувствительность, св занна с неоднородностью рабочей среды.The disadvantage of this method is the low sensitivity associated with the heterogeneity of the working environment.
Целью изобретени вл етс повышение чувствительности.The aim of the invention is to increase the sensitivity.
Указанна цель достигаетс тем, что создают дополнительные акустические колебани с периодически измен ющейс частотой, а частоту колебаний измен ют путем регулировани давлени среды.This goal is achieved by creating additional acoustic oscillations with a periodically varying frequency, and the frequency of oscillations is changed by adjusting the pressure of the medium.
На чертеже представлена схема устройства дл реализации способа.The drawing shows a diagram of the device for implementing the method.
Устройство содержит акустический датчик 1, гидроимпульсатор 2 дл изменени давлени среды в трубопроводе 3 с местом 4 протечки.The device contains an acoustic sensor 1, a hydro-pulse 2 for changing the pressure of the medium in the pipeline 3 with a leakage location 4.
Способ осуществл етс следующимThe method is as follows.
образом.in a way.
В трубопроводе 3 с помощью гидроto импульсатора 2 периодически измен ют давление среды, например с частотой 0,1 т о ,5 Гц.In pipeline 3, the pressure of the medium is periodically changed with the help of a hydroto pulser 2, for example, with a frequency of 0.1 tons, 5 Hz.
При перемещении вдоль трубопровода 3 акустическим датчиком 1 воспринимаютс излучаемые сигналы. В When moving along the pipeline 3, the emitted signals are perceived by the acoustic sensor 1. AT
15 месте 4 протечки трубопровода 3 в принимаемых сигналах по вл етс периодическа составл юща с частотой, равной частоте изменени давлени в трубопроводе 3.15, the location 4 of the leakage of the conduit 3 in the received signals appears periodic with a frequency equal to the frequency of the pressure change in the conduit 3.
