Description
Technical field
The utility model relates to muffler technical field, specially a kind of complex deafener.
Background technique
Silencer refers to for while having the airflow line of noise transmission, can be with the sound absorption pipeline of lining and curved
Head utilizes the noise reductions device such as sectional area sudden change and the discontinuous pipeline of other acoustic impedances, and noise in pipeline is made to be decayed
Or reflect back, the former is known as dissipative muffler, and the latter is known as reactive muffler, also there is the noise elimination of impedance complex formula, silencer
Can be divided into six kinds of main types, i.e., dissipative muffler, reactive muffler, impedance composite muffler, microperforated panel silencer,
Micropole diffusor and active silencer, but existing muffler can not pipeline to different throughput sizes or valve carry out it is effective
Noise reduction, so that it is not convenient to use, for this purpose, it is proposed that a kind of complex deafener.
Utility model content
The purpose of this utility model is to provide a kind of complex deafener, have no matter throughput size, noise reduction effect
The all good advantage of fruit, solve existing muffler can not pipeline to different throughput sizes or valve effectively disappeared
Sound, thus the problem of inconvenient people use.
To achieve the above object, the utility model provides the following technical solutions: a kind of complex deafener, including noise reduction
Pipe, sleeve, bloop, casing and elbow, the middle-end of the noise reduction pipe internal surface offer bloop, and noise reduction tube outer surface
Middle-end is welded with casing, and the right end of noise reduction tube outer surface is welded with elbow.
Preferably, the bloop is provided with four groups, and the angle between every two adjacent groups is 90 degree, while every group disappears
The quantity of sound hole is six to ten, and the distance between adjacent bloop of every two is all the same.
Preferably, the left end of the noise reduction tube outer surface is connected with sleeve by inorganic nano combined binder.
Preferably, the material of the hush pipe, casing and elbow is copper.
Preferably, the welding manner between the hush pipe and casing and elbow is soldering.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model has opened up bloop in the middle-end of noise reduction pipe internal surface, and passes through the effect of casing and elbow, when
When throughput is big, the bloop on hush pipe functions similarly to the effect of resistive sound-absorbing material, and a part of sound can be in porous material
Hole in rub and be converted to thermal energy consumption and dissipate, make to weaken by the sound wave of hush pipe, when throughput is small, due to hush pipe
The pipe of abrupt interface can be formed between casing and room is combined, and forms an acoustic filter, so, when including various frequencies
When the sound wave of rate ingredient enters first bloop, the only sound wave of certain frequencies near first bloop intrinsic frequency
It could be reached in hush pipe by bloop, and the sound wave of other frequency then can not be by bloop, it can only be in noise reduction
Roundtrip in the cell formed between pipe and casing, solving existing muffler can not be to the pipeline of different throughput sizes
Or valve carries out effective noise reduction, thus the problem of inconvenient people use.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
Such as Fig. 1, the utility model includes hush pipe 1, sleeve 2, bloop 3, casing 4 and elbow 5, and bloop 3 is provided with
Four groups, the angle between every two adjacent groups is 90 degree, while the quantity of every group of bloop 3 is six to ten, and every two
The distance between a adjacent bloop 3 is all the same, and the left end of 1 outer surface of hush pipe is connected with by inorganic nano combined binder
Sleeve 2, the middle-end of 1 inner surface of hush pipe offers bloop 3, and the middle-end of 1 outer surface of hush pipe is welded with casing 4, noise reduction
The right end of 1 outer surface of pipe is welded with elbow 5, and when throughput is big, the bloop 3 on hush pipe 1 functions similarly to resistive sound absorption
The effect of material, a part of sound can rub in the hole of porous material and be converted to thermal energy consumption and dissipate, make through hush pipe 1
Sound wave weakens, and when throughput is small, due to that can form the pipe of abrupt interface between hush pipe 1 and casing 4 and room is combined, and is formed
One acoustic filter, so, when the sound wave for including various frequency contents enters first bloop 3, only first
The sound wave of certain frequencies near a 3 intrinsic frequency of bloop could be reached in hush pipe 1 by bloop 3, and other
The sound wave of frequency then can not be by bloop 3, roundtrip in the cell that can only be formed between hush pipe 1 and casing 4, solution
Determined existing muffler can not pipeline to different throughput sizes or valve carry out effective noise reduction, thus inconvenient people
The problem of use, the material of hush pipe 1, casing 4 and elbow 5 are copper, the welding side between hush pipe 1 and casing 4 and elbow 5
Formula is soldering.In use, the other end of elbow 5 and sleeve 2 is connected to pipeline or valve, in the middle-end of 1 inner surface of hush pipe
Bloop 3 has been opened up, and has passed through the effect of casing 4 and elbow 5, when throughput is big, the bloop 3 on hush pipe 1 plays class
It is similar to the effect of resistive sound-absorbing material, a part of sound can rub in the hole of porous material and be converted to thermal energy consumption and dissipate, make
Weakened by the sound wave of hush pipe 1, when throughput is small, due to can be formed between hush pipe 1 and casing 4 abrupt interface pipe and
Room combination, and an acoustic filter is formed, so, when the sound wave for including various frequency contents enters first bloop 3
When, only the sound wave of certain frequencies near first 3 intrinsic frequency of bloop could reach hush pipe 1 by bloop 3
It is interior, and the sound wave of other frequency then can not be by bloop 3, the cell that can only be formed between hush pipe 1 and casing 4
Middle roundtrip, solve existing muffler can not pipeline to different throughput sizes or valve carry out effective noise reduction,
The problem of being used to inconvenient people.
