Abstract

The invention relates to a composite muffler used in a pipeline. The composite muffler used in the pipeline comprises a sound attenuation outer tube. A plurality of labyrinth outer plates and a plurality of labyrinth inner plates are arranged in the sound attenuation outer tube. A plurality of through holes are formed in the sidewall of the sound attenuation outer tube. The two ends of the sound attenuation outer tube are provided with a connecting flange and a flow guide cover respectively. The composite muffler used in the pipeline has the advantages of being simple in structure and convenient to install and use, reducing pressure drop loss of fluid, combining the diffraction sound attenuation principle and the phase-position sound attenuation principle, eliminating turbulent flow and vortexes in the fluid according to the flow rectifying principle and having good sound attenuation effect.

Description

technical field [0001] The invention relates to a muffler, in particular to a compound muffler in a pipeline. Background technique [0002] Most of the mufflers currently on the market are designed solely on the principle of small-hole noise reduction, which has limited noise reduction effects and has a greater resistance to fluids, resulting in greater pressure loss in pipelines. Contents of the invention [0003] The object of the present invention is to provide a compound type silencer in the pipeline in order to overcome the deficiencies of the prior art. [0004] The present invention is realized through the following technical solutions: [0005] The present invention provides a compound muffler in a pipeline, which includes a muffler outer cylinder, a plurality of labyrinth outer plates and labyrinth inner plates arranged in the muffler outer cylinder, and the muffler outer cylinder The side wall is provided with a plurality of through holes, and the two ends of t...
