It may be at least two layers be arranged successively that layer 2, which can be one layer,.For sound absorbing layer 2 the number of plies according to specific use environment with
And requirement does concrete decision, such as the number of plies that needs more higher leveled noise reduction that can increase sound absorbing layer 2.Sound absorbing layer 2
Effect is, when sound absorbing layer 2, which is arranged, wraps pipe shaft 1, the noise sound wave that air-flow generates deeply is inhaled along the hole of hole 1a
Inside sound-absorbing layer 2, rubbing action occurs with the material of sound absorbing layer 2 and converts acoustic energy to thermal energy, to reduce noise.
It is advanced optimized on the basis of said program, sealant 3 is also arranged on the outer wall of sound absorbing layer 2, this is close
Sealing 3 can be one layer or be arranged successively at least two layers, for sealant 3 the number of plies according to specific use environment
And requirement does concrete decision, such as the number of plies that needs more higher leveled sealing effect that can increase sealant 3.Sealant 3
Effect be that, when sealant 3 is set in 2 outer layer of sound absorbing layer, sealant 3 can avoid tube wall gas leakage of the air-flow from pipe shaft 1
The emission effect of air-flow is influenced, also, sealant 3 can also play the role of noise reduction to a certain extent.
Wherein, the material of sound absorbing layer 2 can be acoustical cotton or polyester foam or glass fibre or foamed plastics, sealing
The material of layer 3 is sponge or foam or rubber or acoustical cotton or polyester foam or glass fibre or foamed plastics.Multiple layer sound suction
The material of layer 2 can be identical or different material, and the material of multi-layer sealed layer 3 can be identical or different material.Meanwhile
Sound absorbing layer 2 can be identical or different materials with the material of sealant 3；In order to be carried out the problems such as reducing production cost
Consider, sound absorbing layer 2 and sealant 3 should be identical material, in this way, sealant 3 and the structure that sound absorbing layer 2 is same material support
When part, can reach simultaneously sound-absorbing, sealing function, make sound absorbing layer 2 and sealant 3 in terms of absorbing sound and lowering noise and seal aspect
Effect having the same.
Optionally, hole 1a is distributed in tube wall surrounding part or the surrounding whole of pipe shaft 1.Wherein, the surrounding is whole
It as include the corner transition position between surrounding side wall and side wall.Because the crossover position of tube wall surrounding is difficult the intensive net of processing
Hole, it is contemplated that the relationship of effect and cost, as the preferred embodiment of hole 1a distributions, the tube wall of the hole 1a distribution and pipe shaft 1
Surrounding, the tube wall surrounding are not include the corner transition position of surrounding tube wall.Certainly, if do not consider part production technology and at
This problem can also accomplish the surrounding of pipe shaft 1 all with mesh in the case of at all costs.
Optionally, it may be irregular shape that the shape of hole 1a, which can be regular shape,.In view of production technology
And cost be topic, as the preferred embodiment of hole 1a, hole 1a is designed as regular shape, can be circular hole or square hole or
Elliptical aperture or diamond hole or trapezoidal hole etc..
As the further preferred scheme of hole 1a, hole 1a is designed as circular hole, circular hole processes simple and noise reduction
It is more excellent.When hole 1a is circular hole, aperture 1-8mm, and the pitch of holes between adjacent holes 1a is 2-16mm.Wherein, Kong Jian
Away from more than aperture.
The noise reduction of mesh is allowed to reach preferable level, then the aperture of hole 1a sets me as 2mm, pitch of holes is set
For 4mm.
Optionally, it may be not equal diameter pipe that pipe shaft 1, which can be equal diameter pipe,.Pipe shaft 1 be not equal diameter pipe when, can
Can also be that opposite end is respectively facing the gradual necking in stage casing or flaring to be pipeline of the one end to the gradual necking of the other end or flaring
Pipeline, can also be from one end to other end necking, the pipeline that is arranged alternately successively of flaring.The present embodiment is with one end to another
It is illustrated for the pipeline that one end is gradually flared, wherein the bottom opening of pipe shaft 1 is small compared with its open top.
Optionally, it may be double check valve that valve body, which can be one way stop peturn valve,.One way stop peturn valve is used to have a gas
In the pipe-line system of flow direction, double check valve is applied to tool, and there are two the pipe-line systems of airflow direction or three airflow directions
In.
