If the length of the increase pipe of system, it is easy to which the installing space to natively extremely limited gas handling system causes trouble.
Utility model content
The purpose of this utility model is exactly to provide a kind of novel gas inlet for the defect for overcoming above-mentioned prior art to exist
System resonance chamber.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of gas handling system resonator, including resonator volume, and the neck of resonator volume and admission line is connected,
Characterized in that, described neck is arranged in the resonator volume along admission line pipeline direction, and with vertical air inlet
The heterotypic channel in chimneying direction.
Used as the preferred of such scheme, the heterotypic channel in described neck is in zigzag.
Used as the further preferred of above-mentioned preferred scheme, the heterotypic channel of described neck is divided into three sections, respectively constitutes
Two sections of one section of the level of the interface of admission line, vertical section and level are connected, wherein, it is additionally provided with and admission line in one section of level
Match the interface connected.
As above-mentioned further preferred scheme it is further preferred that described vertical section is spliced by two pairs of parallel risers, institute
The parallel riser of two couples stated is divided into parallel riser a and parallel riser b, and the upper and lower ends of a pair of parallel riser a therein are supported respectively
Top, the bottom of the resonator volume are connect, in another a pair of parallel riser b, one piece of bottom of the riser near the admission line is supported
The bottom of the resonator volume is connect, another piece of riser top away from the admission line abuts the top of the resonator volume
Portion, bottom is suspended from the resonator volume bottom top so that match somebody with somebody with the top of the resonator volume on the vertical section top
Conjunction forms one section of the level, and the vertical section bottom cooperatively forms two sections of the level with the bottom of the resonator volume.
As the further improvement of above-mentioned more preferably scheme, in described parallel riser b, away from the another of the admission line
One piece of riser top rotates with the top of the resonator volume and is connected, and meets：Riser is rotated around the top of resonator volume
When, its side ensures to be in close contact with parallel riser a all the time.
Used as the preferred of such scheme, described resonant cavity G-card connects or welded and installed is on the admission line.
Compared with prior art, the utility model has advantages below：
(1) it is compact attractive in appearance, it is easy to make：Neck is arranged in resonator volume along pipeline, reduce to greatest extent with
The possibility of engine miscellaneous part interference, while resonator is installed using clamping or welding manner.
(2) frequency of noise elimination is low：The length of resonator neck can be to greatest extent lengthened in the heterotypic channel of the neck of zigzag
Degree, in the case where resonator given volume is ensured, reduces the frequency of noise elimination of resonator.
(3) one piece of riser of the vertical section in neck can be rotated around resonator top, so, can change neck with deflecting
The effective length of interior heterotypic channel, and then the frequency of noise elimination of resonator can suitably be adjusted.
Brief description of the drawings
Fig. 1 is the internal structure schematic diagram of resonator of the present utility model；
In figure, 1- necks, the 11- parallel riser b of parallel riser a, 12-, 2- resonator volumes, 3- admission lines.
Specific embodiment
