Existing Double-wall PVC bellows in design, can not accomplish high impact properties, and without the effect eliminated the noise, nothing
Method meets special high-pressure delivery demand.
Utility model content
The purpose of this utility model is to provide a kind of Double-wall PVC bellows of high impact-resistant, to solve above-mentioned background skill
The problem of being proposed in art.
The purpose of this utility model is achieved by following technical proposals：A kind of Double-wall PVC ripple of high impact-resistant
Pipe, including corrugated outer tube body, noise elimination cotton, metal layer, carbon fiber braiding layer, interior tube body, installation cavity, bolster, spring, the wave
Interior tube body is fixed in line outer tube body, and cavity is formed between two tube bodies, is equipped in the cavity and is wrapped in interior tube body successively
The carbon fiber braiding layer and metal layer of outer layer, the outer layer of the metal layer is equipped with the noise elimination cotton for filling up entire cavity, described interior
An installation cavity is equipped in the internal channel of tube body, spring and bolster are equipped in the installation cavity.
Further, the corrugated outer tube body and interior tube body are made of PVC material.
Further, the corrugated outer tube body is fixedly connected with interior tube body, and inside forms a shared internal channel.
Further, the bolster is fixedly connected and is formed by mobile dish, connecting pole and hemisphere bolster.
Further, the installation cavity is combined and is formed by cylinder cavity and round platform cavity, and mobile dish correspondence is installed on institute
It states in cylinder cavity.
Compared with prior art, the Double-wall PVC bellows of this kind of high impact-resistant provided by the utility model, by outer tube and interior
Pipe is formed, and can avoid external force that tube body is caused to rupture with effective protection inner tube, interior to be equipped with noise elimination cotton, metal layer and carbon fiber braiding
Layer not only significantly increases the compression strength of inner tube, and has the effect eliminated the noise, while interior equipped with bolster, can will reach
It is acted on to efficient resistance to compression.
Description of the drawings
Fig. 1 is the overall structure figure of the utility model；
Fig. 2 is the utility model bolster structure chart；
In figure：1st, corrugated outer tube body, 2, noise elimination cotton, 3, metal layer, 4, carbon fiber braiding layer, 5, interior tube body, 6, installation cavity,
7th, bolster, 8, spring, 71, mobile dish, 72, connecting pole, 73, hemisphere bolster.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, the utility model discloses a kind of Double-wall PVC bellows of high impact-resistant, including corrugated outer tube
Body 1, noise elimination cotton 2, metal layer 3, carbon fiber braiding layer 4, interior tube body 5, installation cavity 6, bolster 7, spring 8, the corrugated outer tube
Interior tube body 5 is fixed in body 1, and cavity is formed between two tube bodies 1,5, is equipped in the cavity and is wrapped in interior tube body 5 successively
The carbon fiber braiding layer 4 of outer layer and metal layer 3, the outer layer of the metal layer 3 are equipped with the noise elimination cotton 2 for filling up entire cavity, institute
It states and an installation cavity 6 is equipped in the internal channel of interior tube body 5, spring 8 and bolster 7 are equipped in the installation cavity 6.The corrugated outer tube
Body 1 and interior tube body 5 are made of PVC material.The corrugated outer tube body 1 is fixedly connected with interior tube body 5, and inside forms one and shares
Internal channel.The bolster 7 is fixedly connected and is formed by mobile dish 71, connecting pole 72 and hemisphere bolster 73.The installation cavity 6
It is combined and is formed by cylinder cavity and round platform cavity, the correspondence of mobile dish 71 is installed in the cylinder cavity.
Operation principle；When in use, since the outer layer of interior tube body 5 is equipped with carbon fiber braiding layer 4 and metal layer 3 can be very big
Increase interior tube body 5 compression strength of itself, while the interior bolster 7 that is equipped with is in installation cavity 6 due to can back and forth move horizontally,
Flow velocity with flow in interior tube body 5 freely changes flow bore, so as to reach efficient shock proof effect, avoids impacting with high pressure
Interior tube body 5 is caused to rupture.
