Abstract

The invention discloses a pipe muffler which comprises a muffling shield. An internal muffling member is arranged in the muffling shield and is in a labyrinth structure; the blind end of the muffling shield is arc shaped and is studded with small round holes; the periphery of the body of the muffling shield is studded with rectangular small holes; the other end of the muffling shield is fixedly connected with a flange through bolts or threads; and the muffling shield is made of alloy material. The invention has reasonable structure and good muffling effect.

Description

管道消音器 Pipe muffler

技术领域: FIELD:

[0001] 本发明涉及一种消音器。 [0001] The present invention relates to a muffler. 背景技术: Background technique:

[0002] 现有的消音器由于结构等原因,消音效果并不十分理想。 [0002] a conventional structure due to the muffler, the muffler effect is not very satisfactory. 发明内容: SUMMARY:

[0003] 本发明的目的在于提供一种结构合理,工作效果好的管道消音器。 [0003] The object of the present invention is to provide a reasonable structure, good working effects muffler pipe.

[0004] 本发明的技术解决方案是: [0004] The technical solution of the invention is:

[0005] 一种管道消音器,其特征是:包括消音罩,消音罩内设置消音内件,消音内件为迷宫结构形式,消音罩的盲端呈弧形,消音罩盲端密布圆形小孔,消音罩罩体外周密布矩形小孔,消音罩另一端通过螺栓或螺纹与法兰固定连接;消音罩采用合金材料。 [0005] A pipe muffler, characterized in that: a muffler cover, hood silencer inner member disposed within the muffler, the muffler member form a labyrinth structure, the blind end of the arcuate damping cap, the blind end of the muffler cover small circular clouds hole, hood silencer vitro careful rectangular apertures cloth, muffler cover by bolts or other threaded end is fixedly connected with the flange; muffler cover with alloy.

[0006] 本发明结构合理,消音效果好。 [0006] The present invention reasonable structure and good silencing effect. 声波在通过消音罩后,一部分被加速到超音速,另一部分通过阵列衍射后使声波相互干涉而消音;消音罩内部迷宫结构使气流改变声波的传播途径,使声波在通过消音罩衍射的时候正好产生相位差而干涉,又成为声波分配器,同时对消音罩起支撑和加强作用。 After passing through the acoustic muffler cover portion is accelerated to supersonic speed through another portion of the array of diffracted sound waves interfere with each other muffler; muffler cover to change the air flow inside the labyrinth structure of the acoustic wave transmission, just when acoustic waves diffracted by the silencer cover a phase difference and interference, has become acoustic dispenser, while the damping cap from the support and strengthening the role.

附图说明: BRIEF DESCRIPTION OF:

[0007] 下面结合附图和实施例对本发明作进一步说明。 Drawings and embodiments of the present invention will be further described [0007] below in conjunction.

[0008] 图1是本发明一个实施例的结构示图。 [0008] FIG. 1 is a block diagram of one embodiment of the present invention.

具体实施方式: detailed description:

[0009] 一种管道消音器,包括消音罩1,消音罩内设置消音内件4,消音内件为迷宫结构形式,消音罩的盲端呈弧形,消音罩盲端密布圆形小孔2,消音罩罩体外周密布矩形小孔5, 消音罩另一端通过螺栓或螺纹与法兰3固定连接;消音罩采用合金材料。 [0009] A pipe silencer, the silencer comprises a housing 1, a silencer is provided within the muffler cover member 4, the silencer inner member forms a labyrinth structure, the blind end of the arcuate damping cap, the blind end of the muffler cover densely circular apertures 2 , hood silencer vitro careful rectangular apertures cloth 5, the silencer cover and the other end by a bolt or screw is fixedly connected with the flange 3; muffler cover with alloy.
