Concrete, this utility model is the supporting branch sleeve that is provided with also, and described branch sleeve inwall is provided with female thread.
Concrete, described tube body two ends outer wall is additionally provided with the external screw thread mated with the female thread arranged on branch sleeve inwall.
Further, described branch sleeve is placed on the junction of tube body outer wall upper flange structure and endless groove by the female thread arranged on it with the externally threaded threaded engagement of setting on the outer wall of tube body two ends, pass through branch sleeve, it is possible to make to connect between adjacent tubes body relatively reliable.
Being provided with sealing ring bottom its described endless groove of this utility model, the design of sealing ring can strengthen the sealing property of corrugated tube.
Concrete, described tube body and stupefied bar arranged outside have the anticorrosive coat of film like, and described anticorrosive coat is made up of high-strength polyethylene material.
Concrete, described tube body inwall is provided with wearing layer, described wearing layer is made up of the ceramic particle covered on tube body inwall by binding agent bonding, and ceramic particle also has good wearability while having anti-corrosive properties, make tube body inwall have better anti-wear performance.
Preferably, described tube body adopts soluble poly tetrafluoroethene to make, and politef has good corrosion resistance, high tenacity.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) junction of adjacent two tube bodies of this utility model is additionally provided with branch sleeve on by the basis cooperated of flanged structure and endless groove, makes to connect between adjacent tubes body relatively reliable and difficult drop-off.
(2) inside and outside wall of corrugated tube described in the utility model is provided with anticorrosion antiwear layer, makes overall structure not perishable or abrasion.
(3) this utility model is simple relative to tradition bellows structure, easy for installation.
Accompanying drawing explanation
Fig. 1 is this utility model fragmentary cross-sectional view.
Wherein 1 tube body, 2 peak structure, 3 trough structures, 4 flanged structures, 5 endless grooves, 6 branch sleeves, 7 sealing rings, 8 anticorrosive coats, 9 wearing layers.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, a kind of corrugated tube of long perfomance life, including multiple tube bodies 1 being connected in series, the stupefied bar arranged in the shape of a spiral arranged on described tube body 1, the setting of stupefied bar makes to form multiple peak structure 2 spaced apart and trough structure 3 on tube body outer wall, tube body 1 can be made to be not easy when being subject to applied external force to damage, make it have higher pressure performance, described tube body 1 two ends are also respectively provided with flanged structure 4 and the endless groove 5 mated with flanged structure 4, the flanged structure 4 of described tube body 1 embeds the endless groove 5 of the tube body 1 being adjacent to realize the connection of multiple tube body 1.
