The technical solution advanced optimized is equipped with the first gasket, institute between the first flange and the second flange
It states and is equipped with the second gasket between first flange and the third flange.
The technical solution advanced optimized be the buffering air inlet be it is horn-like, outer diameter is incremented by successively, and with the second method
The blue corresponding other end is equipped with the 4th flange, and the 4th flange is used for external high pressure gas.
The technical solution advanced optimized is that the muffler shell is equipped with the 5th flange corresponding with third flange, institute
The 5th flange is stated for external relevant device.
The technical solution advanced optimized is that the global shape of the silencing pot is round, rectangular, taper or is to be adapted
Irregular shape.
The technical solution advanced optimized be the buffering air inlet, micro silencer mechanism and muffler shell inner surface also
Equipped with quieter material.
The beneficial effects of adopting the technical scheme are that the utility model by horn-like buffering air inlet come
The flow velocity of air-flow in air compressor pipeline is reduced, realizes first order noise abatement；And then again by micro silencer mechanism and
The combination of muffler shell enters micropore noise damping device after second level noise abatement, high pressure draught are cut down by level-one to realize
Structure and compatible muffler shell, cut down in silencing pot and air-flow is in suppressor case by further progress diffusion for gas
The noise that further abatement pipeline interior air-flow generates is realized in interior reflection；The product structure of the utility model is simple, practical, system
At low cost, install convenient is made, it is durable, just applied in air compressor product.
