Detailed description of the invention
As shown in Figure 1 and Figure 2, this programme includes that body 1, the two ends of body 1 set respectively
There is connection end 11, connection end 11 coordinates connecting portion 2, connecting portion 2 are installed
For the connection end 11 of two bodys 1 is integrally connected, in connecting portion 2 inwall
Portion is provided with the annular protrusion 3 with positioning function, is embedded with sealing ring 4 in annular protrusion 3,
The thickness of sealing ring 4, equal to the thickness of annular protrusion 3, sealing ring 4 offers ventilation
Hole 41, two connection ends 11 that two bodys 1 are adjacent support respectively is located at sealing ring 4
Both sides, body 1 includes inner tube 5, is provided with and can increase inner tube 5 machine outside inner tube 5
The metal net layer 6 of tool intensity, is provided with between metal net layer 6 and inner tube 5 and enables to two
Forming the blast resistance construction in space 91 between person, the outside of metal net layer 6 is coated with establishment net
Layer 7, is provided with outer tube 8 outside establishment stratum reticulare 7, establishment stratum reticulare 7 is solid with the inwall of outer tube 8
Fixed connection.
Specifically, blast resistance construction is the bulge-structure 9 being uniformly distributed in inner tube 5 outer wall,
The protruding end of bulge-structure 9 contacts with metal net layer 6, the both sides of bulge-structure 9 with
Space 91 is formed between metal net layer 6.
Saying further, bulge-structure 9 is that dome-type is protruding, the grid of metal net layer 6
The radius that radius is protruding less than dome-type.
Specifically, establishment stratum reticulare 7 is formed by high strength fibre establishment, works out stratum reticulare 7
Being connected by viscose and outer tube 8 inwall are fixing, the inwall of inner tube 5 is coated with flame-retardant layer 51.
Installing for convenience, connection end 11 is provided with external screw thread 11a, and connecting portion 2 leads to
Cross female thread and coordinate installation with the external screw thread 11a on connection end 11.
Specifically, annular protrusion 3 offers annular groove 31, sealing ring 4 sets
There is the bulge loop 42 being embedded in annular groove 31.The both sides of sealing ring 4 are equipped with outwards
