Abstract
The utility model relates to exhaust silencer field, refers to a kind of exhaust silencer structure eliminating the stress that expands with heat and contract with cold particularly.Comprise housing and hush tube, hush tube is arranged in enclosure interior, and hush tube one end is fixed with sheath, and be connected to enclosure interior by sheath interference, the other end is welded on case inside.Hush tube one end in the utility model is connected to housing by the sheath interference fit that can shrink, the other end is welded in housing, when the stress that hush tube is expanded with heat and contract with cold, this stress can be discharged by sheath, the obscission of silencing apparatus because causing by the effect of stress that expands with heat and contract with cold can not be caused, the utility model structure is simple, easy for installation, has great promotional value.
Description
Technical field
The utility model relates to exhaust silencer field, refers to a kind of exhaust silencer structure eliminating the stress that expands with heat and contract with cold particularly.
Background technique
On the vehicle using fuel oil or aircraft, the waste gas that motor produces is discharged via outlet pipe, the gas of direct discharge is because have high flow velocity and pressure can produce extremely strong pneumatic noise, this type of noise spectrum is wide, sound level is high, befouling environment is very big, sometimes its noise level can reach 100 ~ 130dB (A), and this can cause great impact to surrounding enviroment undoubtedly.
In order to eliminate this noise pollution, usually in outlet pipe, install silencing apparatus additional, silencing apparatus can effectively reduce flow velocity and the pressure of gas in outlet pipe, thus reduces the noise of Exhaust Gas generation.In prior art, the silencing apparatus used directly is welded on the housing of outlet pipe usually, both are for being rigidly connected, due to the particular surroundings that silencing apparatus is in, at exhaust phase, the temperature on silencing apparatus surface can reach a few Baidu, consequent effect of expanding with heat and contract with cold, directly can destroy this welded structure, cause noise elimination structure to come off from housing.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides a kind of exhaust silencer structure eliminating the stress that expands with heat and contract with cold.
The technical solution of the utility model is: a kind of exhaust silencer structure eliminating the stress that expands with heat and contract with cold, is characterized in that: comprise housing and hush tube, the circumferential body that described housing has first end, the second end and is arranged between the two;
Described first end, the second end are the ring structure that internal diameter is less than inner major diameter, first end, are provided with the changeover portion of taper between the second end and main body; Described hush tube is placed in housing, and one end end face is connected with the flexible ring jacket that can shrink in axis and radial direction, the other end end face outside is welded in the second end;
Be connected with the inner side of first end outside described ring jacket.
Further described sheath be the many mutual squeeze flow of finer wire together can the ring structure of radial and axial contraction.
Be welded in the end face outside of hush tube inside further described sheath, outside sheath, be connected to interference fit the inner side of first end.
Further described first end is housing air inlet one end.
Hush tube one end in the utility model is connected to housing by the sheath interference fit that can shrink, the other end is welded in housing, when the stress that hush tube is expanded with heat and contract with cold, this stress can be discharged by sheath, the obscission of silencing apparatus because causing by the effect of stress that expands with heat and contract with cold can not be caused, the utility model structure is simple, easy for installation, has great promotional value.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1 ~ 3, be structural representation of the present utility model, comprise housing 1 and hush tube 5, it is inner that hush tube 5 is placed in housing 1.Housing 1 comprises first end 2 and the second end 3, and be provided with the main body 4 of annular between first end 2 and the second end 3, first end 2 and the second end 3 internal diameter are less than the internal diameter of main body 4, and are provided with the changeover portion 6 of taper between main body 4.
Hush tube 5 is the hollow column of ring, and hush tube 5 sidepiece is provided with multiple equally distributed aperture.As shown in Figures 4 and 5, hush tube 5 one end is provided with sheath 7, and sheath 7 is the ring structure formed by the mutual squeeze flow of a lot of finer wire, and axis and radial direction all have the function of contraction.Be welded in the end face outside of hush tube 5 inside sheath 7, hush tube 5 is connected to inside first end 2 by sheath 7 interference fit, sheath 7 is directly filled in first end 2, does not destroy the stability with first end 2 tie point when hush tube 5 can be avoided like this to shake.Hush tube 5 stress produced that expands with heat and contract with cold diametrically can be discharged by sheath 7.Sheath 7 can use other high-temperature-resistant flexible materials to be made, and considers Cost Problems, uses finer wire extruding to form price comparison low, is conducive to using and promoting of this structure.
Hush tube 5 the other end end face outside is welded on inside the second end 3, is fixedly connected with between the two.
The first end 2 that hush tube 5 is connected with housing 1 is the air inlet end of housing 1, and the gas of discharge enters from this one end.
During use, Exhaust Gas enters into hush tube 5 from first end 2, through the obstruction of hush tube 5, reduces flow velocity and the pressure of gas, thus reduces noise pollution.
Hush tube one end in the utility model is connected to housing by the sheath interference fit that can shrink, the other end is welded in housing, when the stress that hush tube is expanded with heat and contract with cold, this stress can be discharged by sheath, the obscission of silencing apparatus because causing by the effect of stress that expands with heat and contract with cold can not be caused, the utility model structure is simple, easy for installation, has great promotional value.
