Description

Pipeline silencer

Technical Field

The utility model relates to a muffler especially relates to an install muffler on pipeline.

Background

In the use process of pipelines, particularly in a drain pipe of an underwater submarine, the pipelines need to be subjected to silencing treatment when being drained, and the traditional pipeline silencing mainly adopts a spiral wedge as a silencing means, but the silencing effect is not obvious.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pipeline muffler that has the damping effect, can frequency control, the noise cancelling effect is good.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a pipeline muffler, includes the pipeline, the pipeline periphery is equipped with spiral sound-absorbing wedge, and the last distribution of sound-absorbing wedge is equipped with a plurality of phonon crystal, and phonon crystal is from the both ends of pipeline to the centre for intensive distribution gradually.

The pipeline is in a hollow cylindrical shape.

The sound absorption wedge is of a triangular structure and is made of rubber.

Both ends of the pipeline are provided with flange edges.

After the structure of the oil-water separator is adopted, the utility model discloses a spiral sound absorption wedge is as foundation structure, and the damping effect when increasing rivers through the pipeline realizes hydraulic degressive effect. And is made of rubber, so that the sound wave and vibration absorption effect can be realized. A plurality of phonon crystals are distributed on the sound-absorbing wedge, so that the silencing effect is enhanced. In order to control the frequency of sound generation, the phononic crystals are distributed gradually and densely from two ends of the pipeline to the middle, the phononic crystals at the two ends can control the low-frequency generation of sound, and the phononic crystal in the middle can control the high-frequency generation of sound.

Fig. 1 is a schematic diagram of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

Referring to fig. 1, a pipeline silencer comprises a pipeline 1, wherein a spiral sound-absorbing wedge 2 is arranged on the periphery of the pipeline 1, a plurality of phonon crystals 3 are distributed on the sound-absorbing wedge 2, and the phonon crystals 3 are gradually and densely distributed from two ends to the middle of the pipeline 1.

Referring to fig. 1, the pipe 1 is a hollow cylinder. Both ends of the pipeline 1 are provided with flange edges 11. The flange 11 facilitates the installation of the pipeline 1.

Referring to fig. 1, the wedge 2 is of a triangular structure and is made of rubber. The sound absorption effect can be guaranteed while the structure is reinforced.

The utility model discloses can be applicable to the drain pipe of submarine, pipeline 1 adopts the hollow circular cylinder design, sets up flange limit 11 at pipeline 1's both ends for installation to pipeline 1. The periphery of the pipeline 1 is provided with a spiral sound absorption wedge 2 to realize the decrease of water pressure. Wedge absorber 2 is triangle-shaped structure, and adopts rubber to make, guarantees structural strength, realizes the absorption to sound wave and vibration. A plurality of phonon crystals 3 are distributed on the sound-absorbing wedge 2, so that the silencing effect is enhanced. And in order to control the frequency of sound generation, the phononic crystals 3 are distributed gradually and densely from two ends to the middle of the pipeline 1, the phononic crystals 3 at the two ends can control the low-frequency generation of sound, and the phononic crystal 3 in the middle can control the high-frequency generation of sound. Therefore, the pipeline 1 of the utility model has the functions of circulation, sound extinction, damping and frequency control.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
