Description

A kind of exhaust pipe silencer
Technical field
This utility model is related to technical field of automobile parts, more particularly to a kind of exhaust pipe silencer.
Background technology
China's automotive industry is developed rapidly, and causes problem of noise pollution increasingly to be verified, car noise becomes people's life The important polluter of environmental quality.Mobile muffler, is mainly used in the noise for reducing producing during the generator operation of motor vehicles, and Discard high temperature safely and effectively to discharge.
The deafener generally existing volume of automobile is larger at present, the general problem of erasure effect.
Utility model content
To overcome above-mentioned deficiency, the invention provides the exhaust pipe silencer of a kind of small volume, good muffling effect.
The technical solution adopted in the utility model is:A kind of exhaust pipe silencer, including cylinder, are arranged on barrel front end Air inlet pipe, is arranged on the exhaustor of cylinder back-end, is provided with active clapboard, stream is provided with the active clapboard in the cylinder Hole, the air inlet pipe are arranged through active clapboard with exhaustor, and the active clapboard forms inlet chamber with cylinder back-end, described Active clapboard forms outlet chamber with barrel front end, is provided with expansion tube, institute in the middle part of the air inlet pipe corresponding to the air inlet intracavity The caliber of the caliber more than two ends air inlet pipe of expansion tube is stated, some through holes on the tube wall of the expansion tube, are evenly arranged with, it is described Screw rod is provided with exhaustor, on the screw rod, flight is provided with.
As the further setting of such scheme, spacing block set, institute in the air inlet pipe corresponding to the outlet chamber, are provided with State active clapboard to move between expansion tube and projection.
As the further setting of such scheme, on the inside of the cylinder, on the inside of air inlet pipe, on the inside of exhaustor and active clapboard On be respectively arranged with muffle coating.
As the further setting of such scheme, on the air inlet pipe and arm, pore is provided with, is arranged on the pore There is silencing cotton.
As the further setting of such scheme, on the flight, pore is provided with.
As the further setting of such scheme, buffer layer on the outer surface of the cylinder, is provided with, the buffer layer is Inflated insert or steel net pad.
The beneficial effects of the utility model are as follows:
1st, the volume of deafener is effectively reduced by the setting of active clapboard;
2nd, active clapboard can be moved in the deafener according to the air-flow of vehicle exhaust, realize inlet chamber and outlet chamber self Adjust, enhance erasure effect.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the present invention.
As shown in figure 1, a kind of exhaust pipe silencer, including cylinder 1, the air inlet pipe 2 of 1 front end of cylinder is arranged on, is arranged on The exhaustor 3 of 1 rear end of cylinder, it is characterised in that:Active clapboard 4 is provided with the cylinder 1, is arranged on the active clapboard 4 There is discharge orifice 41, the air inlet pipe 2 is arranged through active clapboard 4 with exhaustor 3, and the active clapboard 4 is formed with 1 rear end of cylinder Inlet chamber 21, the active clapboard 4 form outlet chamber 31 with 1 front end of cylinder, corresponding air inlet pipe 2 in the inlet chamber 21 Middle part is provided with expansion tube 22, and the caliber of the expansion tube 22 is more than the caliber of two ends air inlet pipe 2, the tube wall of the expansion tube 22 On be evenly arranged with some through holes 23, screw rod 7 is provided with the exhaustor 3, on the screw rod 7, flight is provided with 10;Be provided with spacing block set 24 in air inlet pipe 2 corresponding to the outlet chamber 31, the active clapboard 4 expansion tube 22 with it is convex Move between block 24;Noise reduction painting is respectively arranged with the inside of the cylinder 1, on the inside of air inlet pipe 2, on the inside of exhaustor 3 and on active clapboard 4 Layer;Silencing cotton is provided with the discharge orifice 41 and through hole 23;Pore 9 is provided with the flight 10;Outside the cylinder 1 Buffer layer 8 is provided with surface, the buffer layer 8 is inflated insert or steel net pad.
Operation principle of the present utility model is as follows:
The waste gas of vehicle discharge is imported by air inlet pipe 2 is entered, and the through hole 23 in the outlet of Jing air inlet pipe 2 and expansion tube 22 is entered The mixing decompression of inlet chamber 21, and subtracted wave, subtract ripple sound-absorbing by the noise reduction of silencing cotton;
Meanwhile, waste gas promotes active clapboard 4 to move, and changes the size of inlet chamber 21, so as to change deafener internal structure, Also preferable soundproof effect can be reached in the case where deafener volume is reduced;
Caliber of the caliber of expansion tube 22 more than air inlet pipe 2 so that the pressure of expansion tube 22 can be dropped higher than the pressure outside pipe Low back pressure, solves the air-flow reflux problem that tube wall perforation easily occurs while eliminating the noise;
Waste gas enters outlet chamber 31 via the discharge orifice 41 on active clapboard 4 in inlet chamber 21, and enters exhaustor 3, by arranging On the screw rod 7 and screw rod 7 of 3 Jing hollow forms of trachea, flight 10 passes through to produce rotation with the pore 9 being arranged on flight 10 Whirlpool, and accelerate to discharge into air.
During the entire process of waste gas is by deafener, while by the noise reduction being respectively provided with air inlet pipe 2, exhaustor 3 The noise reduction of coating subtracts wave, the higher erasure effect for improving deafener.
