[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 5As shown in the figure, this utility model embodiment proposes a steam conveying pipeline connection device, which is installed between two steam pipelines to connect the two steam pipelines.

[0025] Please refer to Figure 1 , Figure 2 and Figure 5 The steam conveying pipeline connection device includes a main body 1 and two connecting pipe bodies 2 respectively disposed at both ends of the main body 1. Two movable tubes 3 are symmetrically arranged inside the main body 1. The two ends of the main body 1 are respectively provided with detachable end caps 4, and the end caps 4 are provided with a first through hole 41 for the movable tubes 3 to pass through. When the movable tubes 3 move inside the main body 1, they extend out of or retract into the main body 1. The end of the movable tube 3 that passes through the through hole is provided with a spherical head 31. The side of the connecting pipe body 2 near the main body 1 is provided with a detachable connecting cap 5, and the main body 1 and the connecting cap 5 form a spherical groove 21 that cooperates with the spherical head 31. The main body 1 and the connecting pipe body 2 are movably connected through the cooperation of the spherical head 31 and the spherical groove 21. The movable tube 3 has a through hole 32 connecting the main body 1 and the connecting pipe body 2. The side of the connecting pipe body 2 away from the main body 1 is provided with a transition flange 22, which is used to connect to the steam pipeline.

[0026] Specifically, the operation steps for connecting two steam pipes using the steam conveying pipe connection device provided in this embodiment are as follows: First, mate the adapter flange 22 at one end of one of the adapter pipe bodies 2 with one of the steam pipes. Then, rotate the main pipe body 1 and move the movable pipe 3 until the adapter flange 22 at the other end of the rotating pipe body aligns with the other steam pipe. Finally, mate the adapter flange 22 with the steam pipe to connect the two steam pipes. The steam conveying pipe connection device provided in this embodiment achieves the movable connection between the main pipe body 1 and the adapter pipe body 2 through the cooperation of the spherical head 31 and the spherical groove 21. This allows the main pipe body 1 to rotate arbitrarily relative to the adapter pipe body 2 within a certain range, and the movable pipe 3 can move and extend within the main pipe body 1, thereby connecting two steam pipes at various angles and spaced at a certain distance. This meets the connection requirements of two steam pipes at different angles or with different distances, and has strong versatility.

[0027] like Figure 2As shown, a partition 11 is provided inside the main body 1. The partition 11 is located between the two movable pipes 3 and has a second through hole 12 aligned with the through hole 32. The partition 11 is used to separate the two movable pipes 3 inside the main body 1 and limit the travel of the movable pipes 3 within the main body 1, preventing the spherical head 31 from colliding with the end cap 4 and deforming the spherical head 31, thus affecting the sealing performance of the steam conveying pipeline connection device. The second through hole 12 on the partition 11 connects the two movable pipes 3, ensuring that the conveyed steam can pass through the main body 1.

[0028] Please combine Figure 2 and Figure 3 The main body 1 has a first groove 13 surrounding the opening of the main body 1, and the end cap 4 has a first protrusion 42 that mates with the first groove 13. By providing the first groove 13 on the main body 1 and the first protrusion 42 on the end cap 4 mates with the first groove 13, the first protrusion 42 extends into the first groove 13 after the end cap 4 is installed on the main body 1. This improves the stability of the fit between the end cap 4 and the main body 1, and also enhances the sealing of the main body 1, preventing steam leakage between the end cap 4 and the main body 1.

[0029] In detail, the main body 1 has a first connecting flange 14 at each end, and the end cover 4 has a first mounting hole 43 that mates with the first connecting flange 14. After the end cover 4 is installed on the main body 1, the first mounting hole 43 is aligned with the hole on the first connecting flange 14. At this time, threaded fasteners such as bolts and nuts can be used to fix the end cover 4 on the first connecting flange 14, so that the connection between the end cover 4 and the main body 1 is secure.

[0030] like Figure 3 As shown, the end cap 4 includes a first cap body 44 and a second cap body 45 that cooperate with each other. The first cap body 44 and the second cap body 45 form the through hole, and the first cap body 44 and the second cap body 45 are respectively provided with the first mounting hole 43. The end cap 4 includes a first cap body 44 and a second cap body 45. The first cap body 44 and the second cap body 45, when combined, form the through hole, so as to facilitate the installation of the end cap 4 onto the main pipe body 1 and expose the spherical head 31 on the movable pipe 3 onto the main pipe body 1, thereby facilitating the assembly of the steam conveying pipeline connection device.

[0031] In this embodiment, the first cover 44 has a first positioning groove 46 on the side near the second cover 45, and the second cover 45 has a first positioning protrusion 47 that cooperates with the first positioning groove 46. The first cover 44 and the second cover 45 are positioned by the cooperation of the first positioning groove 46 and the first positioning protrusion 47, ensuring that the first cover 44 and the second cover 45 form a complete ring and close the opening of the main tube 1. Furthermore, the cooperation of the first positioning protrusion 47 and the first positioning groove 46 can improve the sealing performance of the end cap 4 and prevent steam leakage during transportation.

[0032] Please refer to Figure 2 and Figure 4 The adapter pipe body 2 is provided with a second groove 23 surrounding the opening of the adapter pipe body 2, and the connecting cover 5 is provided with a second protrusion 51 that mates with the second groove 23. The second groove 23 surrounding the opening of the adapter pipe body 2 and the second protrusion 51 mate with the second groove 23 on the connecting cover 5, with the second protrusion 51 extending into the second groove 23 after the connecting cover 5 is installed on the adapter pipe body 2, improves the tightness of the fit between the connecting cover 5 and the adapter pipe body 2, and ensures good sealing of the adapter pipe body 2.

[0033] Specifically, the adapter pipe 2 has a second connecting flange 24 at one end near the main pipe 1, and the connecting cover 5 has a second mounting hole 52 that mates with the second connecting flange 24. The connecting cover 5 is installed onto the adapter pipe 2 by using threaded fasteners such as bolts and nuts to fit into the second mounting hole 52 and the hole on the second connecting flange 24, thereby ensuring a reliable connection between the connecting cover 5 and the adapter pipe 2.

[0034] like Figure 4 As shown, the connecting cover 5 includes a cooperating third cover 53 and a fourth cover 54. The adapter pipe 2, the third cover 53, and the fourth cover 54 form the spherical groove 21, and the third cover 53 and the fourth cover 54 are respectively provided with the second mounting hole 52. The connecting cover 5 has a split structure. The third cover 53 and the fourth cover 54 are respectively installed on the adapter pipe 2 to form the spherical groove 21 with the adapter pipe 2. When assembling the steam conveying pipeline connecting device, the spherical head 31 is first placed into the adapter pipe 2, and then the third cover 53 and the fourth cover 54 are respectively connected to the adapter pipe 2 to ensure that the fit between the spherical head 31 and the spherical groove 21 is stable and to prevent the spherical head 31 from disengaging from the spherical groove 21 when the main pipe 1 rotates relative to the adapter pipe 2.

[0035] In detail, the third cover 53 has a second positioning groove 55 on the side near the fourth cover 54, and the fourth cover 54 has a second positioning protrusion 56 that mates with the second positioning groove 55. The second positioning groove 55 on the third cover 53 and the second positioning protrusion 56 on the fourth cover 54 mate with the second positioning groove 55, so that the third cover 53 and the fourth cover 54 form a complete ring after being installed on the adapter pipe 2. Furthermore, the second positioning protrusion 56 extending into the second positioning groove 55 enhances the sealing between the third cover 53 and the fourth cover 54, thereby further improving the reliability of the steam conveying pipeline connection device.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
