Description

(54) УСТРОЙСТВО дл  ОСЛАБЛЕНИЯ ЗВУКОВОГО ПОЛЯ В ТРУБОПРОВОДЕ(54) DEVICE TO REDUCE THE SOUND FIELD IN THE PIPELINE

йей поверхностью трубопровода 6 и расположены поего образующей, Кроме того/ один из излучателей колебанийyay surface of the pipeline 6 and are located on its generators, In addition / one of the emitters of oscillations

5смонтирован с возможностью перемещени  вдоль образующей.трубопровода5 mounted to move along a generator.

6и фиксировани .на рассто нии половины длины изгибной волны в трубопро:воде б от другчэго излучател  колебаний 5.6 and fixing at a distance of half the length of the bending wave in the pipeline: water b from the other oscillator 5.

Распростран ющеес  внутри трубопровода 6 звуковoie поле воздействует через его с.тенку на .приемник здукового ПОЛЯ I,: Йоследаий формирует злектрическ-ий CHPaartVГкошорий./через усилитель ваир же нй  2., фазрарашатель 3 и усилители мсаднортй. 4 поступает на излучатели колебаний5, возбуждающие стенку трубопроводаб .Э;св зи с тем, что рассто ние между излучател ми колебаний 5 равно .половине длины изгибной или упругой волны в/стенке трубопровода 6, то виЬра1 ;Ш в пoc.леднeйJ не раслростран).The sound field propagating inside the pipeline 6 acts through its shade on the receiver of the sound FIELD I ,: A succession forms the electric CHPaart V Gores. / Via the same wire amplifier 2., phaser 3 and the other amplifiers. 4 arrives at oscillation emitters5, which excite the pipe wall .E; because the distance between the oscillators 5 is equal to half the length of the bending or elastic wave in the wall / pipe 6, then vi1; .

Использование  зобретени  позвол ет в значительной степени повысить степень ослаблени , звукового пол  в трубопроводе И уйррстить обслуживание устройства дл  ослаблени  звукового пол  в трубопроводе. Кроме трго, использование изобретени  обеспечивает упрощение констругсции устройства дл  ослаблени  звукового пол  в трубопроводе .The use of the invention significantly increases the degree of attenuation of the sound field in the pipeline, and the maintenance of the device to reduce the sound field in the pipeline. Besides the invention, the use of the invention simplifies the construction of the device for attenuating the sound field in the pipeline.
