Description
Technical field
The present invention relates to silencer technical field more particularly to a kind of heat-insulated noise reduction moulding pipes.
Background technique
The moulding pipe of heat-insulated noise reduction is generally arranged on the outer peripheral surface of the network management of silencer, air-flow passes through in silencer
Mesh in network management forms air flow swirl, and air flow swirl passes through mesh and impacts in the moulding pipe being coated on network management outer peripheral surface.
Existing heat-insulated hush pipe will cause the damage of sound-absorbing material, existing pipe in impact of the long-time by air-flow
Part and sound-absorbing material are all integral structures, and pipe fitting just loses the effect of heat insulation sound absorbent after sound-absorbing material damage, can entirely more
It changes and causes the waste of pipe fitting.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of heat-insulated noise reduction molding proposed
Pipe fitting.
To achieve the goals above, present invention employs following technical solutions:
A kind of heat-insulated noise reduction moulding pipe, including pipe fitting shell, the inner wall of the pipe fitting shell are welded with fixed ring, and fixed
The interior welds of ring have inner tube, and the inside of said inner tube offers the through-hole equidistantly distributed, the pipe fitting shell and inner tube
Between form two completely just as installation cavity, the outer wall of said inner tube has been bolted metal mesh, and metal mesh
Outer wall be bonded with puigging, the outer wall of the puigging is bonded with air bag, and the both ends outer wall of said inner tube is welded with screw thread
Pipe, and the outer wall of two screwed pipes is socketed with sealing ring, the outer wall of two screwed pipes is bolted with ring cowling.
Preferably, the puigging includes filter cotton and peak sponge, and peak sponge is bonded on the outer wall of filter cotton.
Preferably, the outer wall of the fixed ring is socketed with filter cotton, and the inner wall of fixed ring is filled with silencing cotton.
Preferably, the material of the air bag be polyamide material, and the outer wall of air bag open up it is fluted.
Preferably, the outer wall of two ring cowlings offers through-hole, and the size of through-hole and screwed pipe match.
Preferably, the inside of two ring cowlings is filled with centrifugation plexiglas cotton.
The invention has the benefit that
1, this heat-insulated noise reduction moulding pipe, by the way that installation cavity is arranged between inner tube and pipe fitting shell, by installation cavity
Wall sound insulation by filling layer helps pipe fitting noise reduction, by the way that inflatable air bag is arranged in installation cavity wall, is laminated sound insulation by air bag
Tightly air-flow is avoided to flow out, and be convenient for changing the puigging in installation cavity in the both ends of pipe fitting setting ring cowling, solves pipe fitting waste
The problem of.
2, metal mesh, the impurity that will be carried secretly in air-flow is arranged by the outer wall in inner tube in this heat-insulated noise reduction moulding pipe
It is filtered and impurity is avoided to enter puigging, installation cavity is sealed by gasket, air-flow is avoided to run out of, in fixed ring
The material of upper setting sound-absorbing avoids sound from propagating out by fixed ring.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of heat-insulated noise reduction moulding pipe proposed by the present invention；
Fig. 2 is a kind of schematic cross-sectional view of heat-insulated noise reduction moulding pipe proposed by the present invention.
In figure: 1 pipe fitting shell, 2 ring cowlings, 3 fixed rings, 4 inner tubes, 5 through-holes, 6 screwed pipes, 7 sealing rings, 8 metal meshes, 9 every
Sound-absorbing layer, 10 air bags.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1-2, a kind of heat-insulated noise reduction moulding pipe, including pipe fitting shell 1, the inner wall of pipe fitting shell 1 are welded with
Fixed ring 3, and the interior welds of fixed ring 3 have inner tube 4, the inside of inner tube 4 offers the through-hole 5 equidistantly distributed, pipe fitting
Formd between shell 1 and inner tube 4 two completely just as installation cavity, the outer wall of inner tube 4 has been bolted metal mesh
8, and the outer wall of metal mesh 8 is bonded with puigging 9, the outer wall of puigging 9 is bonded with air bag 10, and the both ends outer wall of inner tube 4 welds
It being connected to screwed pipe 6, and the outer wall of two screwed pipes 6 is socketed with sealing ring 7, the outer wall of two screwed pipes 6 is bolted with ring cowling 2, every
Sound-absorbing layer 9 includes filter cotton and peak sponge, and peak sponge is bonded on the outer wall of filter cotton, and the outer wall of fixed ring 3 is socketed with
Filter cotton, and the inner wall of fixed ring 3 is filled with silencing cotton, the material of air bag 10 is polyamide material, and the outer wall of air bag 10 is equal
