Description

Novel muffler air inlet pipe

Technical Field

The utility model relates to the technical field of silencers, in particular to a novel silencer air inlet pipe.

Background

The muffler means that for the air flow pipeline with noise transmission, the noise in the pipeline can be attenuated or reflected back by using the pipeline with sound absorption lining and elbow or using the noise reduction devices such as the pipeline with suddenly changed sectional area and other discontinuous acoustic impedance. The former is called resistive muffler, and the latter is called resistive muffler, and there is also a resistive composite muffler. The air flow channel in the air inlet pipe of the existing muffler has a simple structure, and the air flow path is shorter under the condition that the whole length of the muffler is smaller, so that the ideal silencing effect cannot be achieved.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide the novel muffler air inlet pipe which is reasonable in structure and good in using effect.

In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: the utility model provides a novel muffler intake pipe, it is including the main part, the connecting plate is installed at main part both ends, the main part including outer pipeline and pipeline, the pipeline is installed in outer pipeline, the inside wall of outer pipeline is equipped with the amortization hole that a plurality of indent formed, a plurality of amortization hole evenly distributed is on outer pipeline, be equipped with the inside and outside through-hole that runs through of a plurality of on the pipeline, a plurality of through-hole evenly distributed is on the pipeline, through the through-hole intercommunication between pipeline inner chamber and the outer pipeline inner chamber, pipeline inside wall is equipped with the amortization groove that the indent formed.

The silencing groove is in a thread shape.

The connecting plate outside be equipped with the indent and form the seal groove, install sealed pad in the seal groove.

The edge of the connecting plate is provided with a connecting hole which penetrates through the connecting plate.

After the scheme is adopted, the connecting plate at one end of the main body is connected with the air outlet pipe of the engine, the connecting plate at one end of the main body is connected with the muffler, the installed connecting plate is sealed through the sealing gasket, noise-containing air flow generated during engine operation is led into the inner pipeline through the air outlet pipe, one part of the noise-containing air flow in the inner pipeline is silenced through the silencing groove, the other part of the noise-containing air flow passes through the through hole and is led into the outer pipeline and is silenced through the silencing hole, the silenced air flow passes through the through hole and enters the inner pipeline, and is led into the muffler through the inner pipeline to be silenced again; the utility model has reasonable structure and good use effect after adopting the scheme.
