Abstract
1. Устройство контроля герметичности запорной арматуры трубопровода, содержащее акустический датчик с усилителем сигналов, отличающееся тем, что к усилителю сигналов подключен регулируемый полосовой фильтр, на выходе которого установлен преобразователь переменного тока в постоянный, соединенный с блоком памяти амплитуд сигналов, к которому подключен индикатор амплитуд сигналов, свидетельствующих о состоянии герметичности запорной арматуры.2. Устройство контроля герметичности запорной арматуры трубопровода по п.1, отличающееся тем, что блок памяти амплитуд сигналов содержит ячейки памяти амплитуд сигналов при открытом, закрытом и промежуточном положениях запорной арматуры, соединенных переключателем с преобразователем переменного тока в постоянный.1. The tightness control device of pipeline shutoff valves, comprising an acoustic sensor with a signal amplifier, characterized in that an adjustable band-pass filter is connected to the signal amplifier, the output of which is equipped with an AC / DC converter connected to the signal amplitude memory block to which the amplitude indicator is connected signals indicating the state of tightness of stop valves. 2. The tightness control device of pipeline shutoff valves according to claim 1, characterized in that the signal amplitude memory unit contains signal amplitude memory cells with open, closed and intermediate positions of shutoff valves connected by a switch to an AC / DC converter.
