And outlet air end；The body is provided at both ends with internal thread；The air intake is additionally provided with grid；The silencing cotton is cylindrical shape,
It is arranged in bend；Fastener is additionally provided with the bend；The silencing cotton two ends are fastened in fastener；The fastener
With radian；The support bar is arranged on body inner ring side.
It is preferred that, the silencing cotton is pasted onto on bend internal face.
It is preferred that, the fastener is class annular, including arc-shaped base and fastening plate.
It is preferred that, the fastener is arc, is evenly distributed on silencing cotton two ends.
It is preferred that, the bend outside wall surface is provided with silencing cotton.
(3) beneficial effect
The utility model provides a kind of wear-resisting muffling air duct elbow, is provided with grid in elbow air intake, sets in bend
Silencing cotton has been put, has allowed airflow into after elbow and first to decompose, contact again with silencing cotton, noise reduction is realized by buffering, gas is also alleviated
Flow the shock to body；Support bar is provided with inner side of elbow simultaneously, strengthens stability.
Brief description of the drawings
