Description

противоположных концах трубопровода, пос-, ле чего по измеренным интервалам времени и известным длинам участков между датчиками определ ют рассто ние от начала или конца контролируемого участка до места повреждени .opposite ends of the pipeline, after that, the distance from the beginning or end of the test section to the point of damage is determined from the measured time intervals and the known lengths of the sections between the sensors.

На чертеже изображена схема устройства дл  осуществлени  предлагаемого способа .The drawing shows a diagram of an apparatus for carrying out the proposed method.

Дл  регистрации волн давлени , возникающих в месте повреждени , на противоположных концах контролируемого участка трубопровода 1 на произвольном равном рассто нии один от другого устанавливают по два датчика 2 и 3, 4 и 5 давлени , чувствительных к действию волны разрежени , возникщей в месте повреждени  и распростран ющейс  по перекачиваемым продуктам вдоль, трубопровода с кодирующими устройствами 6 и 7, 8 и 9, св занными с регистрирующим прибором 10.To register pressure waves arising at the damage site, at the opposite ends of the monitored section of pipeline 1, two pressure sensors 2 and 3, 4 and 5 are installed at an arbitrary equal distance from each other, which are sensitive to the action of the rarefaction wave that occurs at the damage site and propagate along the pumped products along, the pipeline with encoders 6 and 7, 8 and 9 connected to the recording device 10.

При достижении через определенный интервал времени фронтом одной из волн датч ика 2, последний срабатывает и посылает кодированный сигнал на регистрирующий прибор 10. ; When, at a certain time interval, the front of one of the waves of sensor 2 is reached, the latter is triggered and sends a coded signal to the recording device 10.;

После дещифрации и обработки сигнала декодирующее устройство, совмещенное с прибором 10, выдает соответствующий электрический сигнал, который производит включение счетчика № I импульсов времени. При подходе волны давлени  к датчику 3, последний срабатывает и посылает сигнал на прибор 10, который производит остановку счетчика № 1 импульсов времени и запускает в работу счетчик № 2.After deciphering and processing the signal, the decoding device combined with the device 10 generates a corresponding electrical signal, which turns on the counter No. I of the time pulses. When a pressure wave approaches the sensor 3, the latter triggers and sends a signal to the device 10, which stops the counter No. 1 of the time pulses and starts up the counter No. 2.

Через определенный интервал времени фронт волны давлени , распростран ющийс  в противоположную сторону от места повреждени , достигает датчика 4, который срабатывает и посылает сигнал на прибор 10, который запускает в работу счетчик № 3. При подходе волны давлени  к датчику 5 последний срабатывает и посылает на прибор 10 кодированный сигнал, который производит остановку счетчиков № 2 и № 3,After a certain time interval, the front of the pressure wave, propagating in the opposite direction from the damage site, reaches sensor 4, which is triggered and sends a signal to device 10, which triggers meter 3. When a pressure wave approaches the sensor 5, the latter triggers and sends to the device 10 is a coded signal that stops the counters No. 2 and No. 3,

. По измеренным интервалам времени и известным длинам участков между датчиками давлени  определ ют место повреждени  трубопровода.. The location of damage to the pipeline is determined from the measured time intervals and the known lengths of sections between the pressure sensors.
