Mark in figure: 10-first connection pipe body, 11-open-mouth section, 20-second connection pipe body, 21-pipe shoulder, 30-main pipe, 31-cavity section, 32-closing in section, 41-first seal ring assembly, 42-second seal ring assembly.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of connection for underground pipe network of the present invention is stretched pipe fitting, main pipe 30, first connection pipe body 10 and the second connection pipe body 20, wherein, main pipe 30 comprises cavity section 31 and closing in section 32, and the internal diameter of closing in section 32 is less than the internal diameter of cavity section 31; One end of second connection pipe body 20 is provided with pipe shoulder 21, and pipe shoulder 21 is arranged in the cavity section 31 of main pipe 30, the other end of the second connection pipe body 20 stretches out outside the closing in section 32 of main pipe 30, the external diameter of pipe shoulder 21 is greater than the internal diameter of closing in section 32, the pipe shoulder 21 of the second connection pipe body 20 is arranged with the first seal ring assembly 41 offseted with cavity section 31 inwall of main pipe 30, and closing in section 32 inwall of main pipe 30 is embedded with the second seal ring assembly 42 offseted with the outer wall of the second connection pipe body 20; One end of first connection pipe body 10 is set to open-mouth section 11, open-mouth section 11 preferably adopts horn-like uncovered, first connection pipe body 10 is connected with cavity section 31 end winding support of main pipe 30 by the end of open-mouth section 11, and the internal diameter of the miner diameter end of the open-mouth section 11 of the first connection pipe body 10 is less than pipe shoulder 21 external diameter of the second connection pipe body 20.
Connection of the present invention is stretched pipe fitting, and as the link between pipe fitting and pipe fitting, be fixedly connected with other tubing by the first connection pipe body 10, the second connection pipe body 20 is fixedly connected with other tubing, thus realizes the connection between tubing and tubing.External diameter due to the pipe shoulder 21 of the second connection pipe body 20 is greater than the internal diameter of the miner diameter end of the internal diameter of the closing in section 32 of main pipe 30 and the open-mouth section 11 of the first connection pipe body 10, therefore, the pipe shoulder 21 of the second connection pipe body 20 is limited in the cavity section 31 of main pipe 30, and can slide axially along main pipe 30, occur expanding with heat and contract with cold etc. between the tubing connected situation time, slide in the cavity section 31 of main pipe 30 by the second connection pipe body 20, eliminate produce because expanding with heat and contract with cold between tubing and tubing flexible, and the internal stress between elimination tubing.
First connection pipe body 10, second connection pipe body 20 is connected and fixed with other tubing can by being welded to connect, also can adopt and be threaded, when employing is threaded, can process screw thread in the end of the first connection pipe body 10 and the second connection pipe body 20 respectively, screw thread can be internal thread also can be outside thread; Groove can be processed in the end of the first connection pipe body 10 and the second connection pipe body 20 respectively, adopt groove to be connected with other tubing; Also can install flange plate in the end of the first connection pipe body 10 and the second connection pipe body 20 respectively, adopt flange plate to be connected with other tubing, also respectively integrated flange can be set in the end of the first connection pipe body 10 and the second connection pipe body 20.
First connection pipe body 10 is by fixing by being welded to connect fixing, Flange joint or being threaded fixing between the end of open-mouth section 11 and cavity section 31 end of main pipe 30.
The axial length of the cavity section 31 of main pipe 30 is 5-3000mm, makes the inner chamber of the cavity section 31 of main pipe 30 be 5-3000mm, and therefore the relative telescopic distance of main pipe 30 and the second connection pipe body 20 is the longest reaches 5000mm.If when the cavity length of cavity section 31 is longer, also multistage welding shaping method can be adopted to make described cavity section 31, the mode that also multistage can be adopted to be threaded makes described cavity section 31, one-time formed method can certainly be adopted, and in the flexible pipe fitting creep process of connection, tubing is interconnected and forever can not comes off, and is the connection that rigidity and toughness have both, and is applicable to size tubing and uses.
First black box is provided with 2-3 O RunddichtringO, and the second black box is provided with 2-3 O RunddichtringO.First black box and the second black box also can be the seal ring of other shapes, and the quantity of seal ring can be any fair amount according to pressure size and collapsing length.By arranging the first seal ring assembly 41 and the second seal ring assembly 42, form the double seal between the second connection pipe body 20 and main pipe 30, make the sealing effect between the second connection pipe body 20 and main pipe 30 better, after preventing long-time use, occur leaking.
