Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of low-noise muffler, including the first hush pipe 3 and the second hush pipe 4, the first noise reduction
The side open end appearance wall of pipe 3 offers card slot 6, and the inside of card slot 6 is connect by snap ring 7 with the second hush pipe 4, and first
The outer surface of hush pipe 3 and the second hush pipe 4 is socketed with grip ring 1, the two sides appearance of the first hush pipe 3 and the second hush pipe 4
Wall is communicated with water inlet pipe 2 and outlet pipe 5 respectively, and the inside of the first hush pipe 3 and the second hush pipe 4 is embedded with water cooling tube
33, the inner surface wall input end of the first hush pipe 3 is welded with threaded block 32, and the inner surface wall outlet end of the first hush pipe 3, which is welded with, to disappear
Sound bowl 34, the inner surface wall of the second hush pipe 4 is embedded with acoustical cotton plate 42, and the side of acoustical cotton plate 42 is pasted with flow distribution plate 41,
