Detailed Description

As shown in fig. 1 to 3, a novel single pipe expansion joint, it adopts brand-new structural design, the connection position through with bellows both ends sets up the welded structure of a vertical direction of welding usefulness, area of connection when guaranteeing the welding cooperation is bigger, welding position's space is bigger, welding operation is more convenient, holistic joint strength is also reliable, the size that has still ensured bellows left and right sides connection position simultaneously is the same, can ensure that the extension of bellows is in the horizontality when using, it is stronger to have ensured the durability when using, the damage to the bellows main part in the use has been reduced, make holistic life longer, and can satisfy the user demand under the multiple application environment. It includes that the center pin is the main steel tubular construction 7 of left right direction, the outside of main steel tubular construction 7 is equipped with bellows major structure 2, the left and right sides of bellows major structure 2 is equipped with integrated into one piece's welding cooperation post 21, left side respectively the left side terminal surface position welded connection of welding cooperation post 21 has short connector 1, short connector 1's left side with main steel tubular construction 7 welded connection is in the same place, the right side terminal surface position of welding cooperation post 21 is connected with the size adapter 3 that the size becomes from the left side right side in proper order through the welded mode, can satisfy the assembly demand of the different mounting structure of whole left right direction mounted position size. Big small adapter 3's inside with be equipped with thermal-insulated cotton 4 between main steel tubular structure 7's the outside, the right side terminal surface position of big small adapter 3 is equipped with reinforcement safety shield 5, avoids thermal-insulated cotton 4 to run out easily in the use. The right side of reinforcing safety shield 5 with 7 hookup locations of main steel tubular construction are equipped with interface installation locating plate 6, can play the effect of positioning when carrying out the installation cooperation of right side structure, also can improve the cooperation intensity of right side mounted position simultaneously. The interface installation positioning plate 6 is connected with the main steel pipe structure 7 in a welding mode, and the integral structural strength is guaranteed to be better.
