Abstract
The utility model relates to a variable general muffler of pipeline axial high -efficient wide band section of welding becomes at inward two the at least interpolation nests of tubes of pipeline axle by setting up, and the intubate is guaranteed sealedly with the person in charge welded connection of pipeline in each. Compared with the prior art, the utility model discloses but the structure excursion is big, can form mufflers much more more, and the design of muffler is carried out in make full use of pipeline space, and application scope is wider, and through changing intubate in two, technology and structure can be freer, and through the choosing of intubate in different, the amortization frequency can cover up to more than the 10000HZ in addition, in addition, and on a welding region or plane, with two persons in charge and two interior intubate are welded occasionally.
Description
Technical field
This utility model relates to a kind of deafener, especially relates to a kind of pipeline and axially welds the variable general deafener of high-efficiency broadband section.
Background technology
At present, along with the proposition of vehicle platform concept, the vehicle car load border of same OEM exploitation is roughly the same, which results in the product versatility requirement of gas handling system and is greatly improved, simultaneously because the large-scale use of turbocharged engine, the demand for high frequency deafener is more and more higher. But owing to engine displacement is different, the configuration of turbocharger is different, causing the varying of performance of gas handling system, therefore, the general deafener that a kind of frequency range how can be provided variable has just become technical problem urgently to be resolved hurrily.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of frequency of noise elimination width is provided, the pipeline of applied range axially welds the variable general deafener of high-efficiency broadband section.
The purpose of this utility model can be achieved through the following technical solutions:
Pipeline axially welds the variable general deafener of high-efficiency broadband section, being made up of the several interpolation pipes being arranged on pipeline axially interior, the supervisor of each interpolation pipe and pipeline is welded to connect guarantee and seals, by changing interpolation pipe, it is capable of in different automobile types, different electromotors realizes deafener and shares.
Described interpolation pipe is at least provided with two, and the space that two interpolation pipes change than single interpolation pipe is greatly. It is possible to form the frequency of noise elimination more enriched than single interpolation pipe.
Described interpolation pipe is enclosed construction, and the inwall of the projection in interpolation pipe and supervisor forms the different size of cavity that can eliminate the noise.
It is additionally provided with noise elimination cotton in one or more cavitys, reaches to eliminate the effect of high frequency wideband frequency of noise elimination.
Described pipeline is made up of two supervisors, has all been welded to connect interpolation pipe in each supervisor, so in a welding region or plane, has two supervisors and two i.e. four assemblies of interpolation pipe to weld simultaneously.
Described interpolation pipe can be connected with the supervisor of pipeline through the mode of hot plate welding, hot-gas welding, Vibration welding or laser weld, being tightly connected of pipeline is ensured by welding, the airtight cavity simultaneously formed by this welding can play the effect of noise elimination, when sound passes through the pipeline with cavity, sound can reach decay, noise for characteristic frequency, it is possible to reduce several decibels to tens decibels are not etc., thus reaching the function eliminated the noise.
Compared with prior art, this utility model has the advantage that
One, structurally variable scope is big, can form more deafener, make full use of pipeline space and carry out the design of deafener.
Two, the scope of application is wider, and by changing double interpolation pipe, technique and structure can be freer
Three, more extensive for frequency, by choosing of different interpolation pipe, noise reduction frequency can cover up to more than 10000HZ.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Embodiment
Pipeline axially welds the variable general deafener of high-efficiency broadband section, the structure of its application is as shown in Figure 1, it is made up of the several interpolation pipes being arranged on pipeline axially interior, the supervisor of each interpolation pipe and pipeline is welded to connect guarantee and seals, the present embodiment includes being respectively welded the first interpolation pipe 3 and the second interpolation pipe 4 being connected in the first pipeline 1 and the second pipeline 2, and its structure is as Figure 2-3. The space that two interpolation pipes change than single interpolation pipe is greatly. It is possible to form the frequency of noise elimination more enriched than single interpolation pipe, it can in addition contain by changing interpolation pipe, it is possible to realize in different automobile types, different electromotors realize deafener and shares. So in a welding region or plane, there are the first pipeline 1 and the second pipeline 2 and the first interpolation pipe 3 and the second interpolation pipe 4 i.e. four assemblies to weld simultaneously.
First interpolation pipe 3 and the second interpolation pipe 4 are all enclosed construction, the inwall of the projection in interpolation pipe and supervisor forms the different size of silencing cavity 5 that can eliminate the noise, can also pass through as required to add specific noise elimination cotton filled chamber in silencing cavity 5, reach to eliminate the effect of high frequency wideband frequency of noise elimination, such as can fill silencing cotton in one of which or multiple silencing cavity 5, if having reached good erasure effect, it is also possible to be not filled with silencing cotton. Interpolation pipe can be connected with the supervisor of pipeline through the mode of hot plate welding, hot-gas welding, Vibration welding or laser weld, the present embodiment adopts laser weld, so can ensure that being tightly connected of pipeline, the airtight cavity simultaneously formed by this welding can play the effect of noise elimination.
