Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide a kind of π type array type silencer, to solve
The common array type silencer of the prior art is existed using rectangle inserted sheet square or triangular array layout, such array silencer
The low problem of distribution of air flow, inserted sheet intensity, wideband noise reduction effect.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of π type array type silencer, including suppressor case, inserted sheet pod, noise elimination inserted sheet and inserted sheet install guide rail,
The case inside front and back end is welded with inserted sheet installation guide rail, carries out bolt company with pod on the inside of the installation guide rail
It connects, is welded on the outside of the pod rear end with noise elimination inserted sheet.
Further, the noise elimination inserted sheet uses π type array layout, and π type array layout uses one by three noise elimination inserted sheets
The perpendicular layout composition of cross two.
Further, there are two the pod settings, two pods use big inclined-plane trapezium structure, and big inclined-plane is trapezoidal
Structure bevel angle is less than 15 °.
Further, it is made of on the outside of the noise elimination inserted sheet two length inserted sheets and width inserted sheet, length inserted sheet and width
Inserted sheet is that rectangular section, length inserted sheet width inserted sheet ratio 1:3, and inserted sheet aperture are less than 1mm, noise elimination inserted sheet surface percent opening
> 20%.
Further, sound-absorbing material plate is filled with inside the length inserted sheet and width inserted sheet.
Further, the sound-absorbing material plate matter is polyester fiber board.
Compared with prior art, the utility model has the following beneficial effects: a kind of π type array type silencer, eliminates the noise
Inserted sheet uses rectangle inserted sheet form, the installation of π type array, and structural strength increases, and degree of disturbing reduces；Inserted sheet pod uses big inclined-plane
Trapezium structure, more evenly, air drag is effectively reduced in the more stable distribution of air-flow, internal also to use polyester fiber 3D template, wideband
Noise reduction effect is high, and compared with conventional muffler, the sound absorber width of type array noise elimination inserted sheet increases, and total absorption area increases,
Whole sound deadening capacity improves, and than being 50% or more, air-flow is uniformly distributed the circulation of type array noise elimination inserted sheet, and wind speed reduces between piece, gas
It is smaller to flow regenerated noise, solves common array type silencer and is laid out using rectangle inserted sheet square or triangular array, this
The class array silencer problem low in distribution of air flow, inserted sheet intensity, wideband noise reduction effect.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1-3, a kind of π type array type silencer, including suppressor case 1, inserted sheet pod 2, noise elimination inserted sheet 3
Guide rail 4 is installed with inserted sheet, 1 inside front and back end of shell is welded with inserted sheet installation guide rail 4,4 inside of installation guide rail and pod 2
It is bolted, is welded on the outside of 2 rear end of pod with noise elimination inserted sheet 3.
Therein, the noise elimination inserted sheet 3 uses π type array layout, and π type array layout uses one by three noise elimination inserted sheets 3
The perpendicular layout composition of cross two, novel form, landscape are strong.
Therein, there are two the settings of pod 2, and two pods 2 use big inclined-plane trapezium structure, and big inclined-plane is trapezoidal
