Between wall, and the inner sidewall of the lateral wall and outer tube of wire and inner tube offsets, said inner tube lateral wall, outer tube inner sidewall and
Also there is leakage object delivery space between wire, the both ends of the leakage object delivery space extend respectively to the both ends of tube body.
Such double-wall pipe, increasing between inner and outer tubes has wire, and wire makes to be formed between inner and outer tubes between leakage object discharge
Gap is processed to avoid on outer wall of inner tube or outer tube wall, manufacture easy to produce, and at low cost.
The purpose of this utility model can also be solved using following technical measures:
As a kind of more specific scheme, the wire is extended to the other end of tube body, tube body both ends by tube body one end
There is the outlet of leakage object delivery space, leakage logistics goes out to be easy, to find the problem of tube body is revealed in time.
As a kind of more specific scheme, it is provided with resettlement groove between the lateral wall of said inner tube and the inner sidewall of outer tube,
The wire is placed on resettlement groove, the resettlement groove remaining part between said inner tube lateral wall, outer tube inner sidewall and wire
The leakage object delivery space is constituted, wire is limited by resettlement groove and fixed, and is kept clear to ensure to reveal object delivery space.
As the first scheme, the resettlement groove is arranged on the lateral wall of inner tube.
As second scheme, the resettlement groove is arranged on the inner sidewall of outer tube.
As the third scheme, the resettlement groove is separately positioned on the lateral wall of inner tube and the inner sidewall of outer tube.
As a kind of more specific scheme, the wire and resettlement groove are disposed in a vertical manner on tube body.
Alternatively, the wire and resettlement groove are arranged on tube body with coiled fashion.
The beneficial effects of the utility model are as follows:
(1) such double-wall pipe, increasing between inner and outer tubes has wire, and wire, which makes to be formed between inner and outer tubes, to be let out
Reveal object delivery space, is processed to avoid on outer wall of inner tube or outer tube wall, manufacture easy to produce, and at low cost, tube body
There is the outlet of leakage object delivery space at both ends, and leakage logistics goes out to be easy, to find the problem of tube body is revealed in time；Wire
It is limited and is fixed by resettlement groove, kept clear with ensuring to reveal object delivery space.
