Description

Technical Field

[0001] This utility model relates to the field of gas transmission equipment technology, specifically to an expansion joint for a labyrinth spherical double-compensation structure air supply device. Background Technology

[0002] The labyrinth spherical double-compensation structure expansion joint for air supply systems is a flexible connection component specifically designed for air supply systems. Its core features lie in its labyrinthine internal structure and spherical double-compensation mechanism. The labyrinth structure typically consists of a series of tortuous channels designed to reduce pressure loss during airflow and potentially enhance sealing performance. The spherical double-compensation structure allows the expansion joint to compensate for displacement in multiple directions. This capability stems from its internal or external design with spherical contact or sliding surfaces, enabling the connection ends to rotate and move relative to each other within a certain range. This effectively absorbs deformation of the pipeline caused by thermal expansion and contraction, installation errors, or external loads, protecting the air supply device and related pipelines from stress damage and ensuring the stability and reliability of the system operation.

[0003] In existing applications of expansion joints in air supply systems, the expansion joint is typically installed on the outer wall of the outer casing, while the end furthest from the casing needs to be connected to a pipe, resulting in an increase in the overall weight of the expansion joint. To cope with the thermal expansion and contraction and vibration of the pipe, the outer casing is designed to drive the expansion joint to rotate and adjust the angle, thereby achieving multi-directional displacement compensation.

[0004] However, this design has the following problems in actual use: Although the support frame at the bottom of the expansion joint can share some of the weight, the installation and connection of the support frame becomes complicated because the expansion joint needs to rotate with the outer sphere during use. It requires repeated handling and re-fixing, which leads to inconvenience in operation and affects installation efficiency and flexibility of use. Therefore, a labyrinth spherical double compensation structure air supply device expansion joint is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an expansion joint for a labyrinth spherical double-compensation structure air supply device. This expansion joint offers advantages such as improved ease of adjustment and use of the support structure. It also solves the problem that existing support structures require reconnection and reinstallation of the support structure to the expansion joint after the expansion joint is rotated to adjust its angle, which is inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An expansion joint for a labyrinthine spherical double-compensation structure air supply device includes a base, an expansion joint, and two flanges. The base has a compensation component inside and a support structure on top.

[0008] The compensation component includes a support shaft fixedly connected inside the base, a labyrinth sphere fixedly connected to the top of the support shaft, an outer spherical shell rotatably connected inside the base, and an air outlet pipe fixedly connected to the outer peripheral wall of the outer spherical shell.

[0009] The support structure includes a mounting ring rotatably connected to the outer peripheral wall of the base, a support seat fixedly connected to the outer peripheral wall of the mounting ring, a support rod fixedly connected to the top of the support seat, a support ring fixedly connected to the top of the support rod, four mounting seats fixedly connected to the outer peripheral wall of the expansion joint, a reinforcing rod slidingly passing through the interior of two of the mounting seats, and two nuts threadedly connected to the outer peripheral wall of the reinforcing rod.

[0010] Furthermore, a mounting rod is fixedly connected to the bottom of the support base, and a pulley seat is fixedly connected to the bottom end of the mounting rod.

[0011] Furthermore, the two flanges are movably connected to the left and right ends of the expansion joint, respectively, and two bolts are movably installed between the flanges and the expansion joint.

[0012] Furthermore, the flange on the left is fixedly connected to the right end of the air outlet pipe, and the flange on the right is fixedly connected to the right end of the connecting pipe.

[0013] Furthermore, an air inlet pipe is fixedly connected to the top of the outer spherical shell, and the labyrinth sphere is rotatably connected to the inside of the outer spherical shell.

[0014] Furthermore, a perforation is provided at the bottom of the outer spherical shell, and the support shaft is rotatably connected inside the perforation, with the size of the support shaft matching that of the perforation.

[0015] Furthermore, the mounting base has an internal mounting hole, and the reinforcing rod is slidably connected inside the mounting hole, with the reinforcing rod being adapted to the size of the mounting hole.

[0016] Furthermore, the support ring has two connecting holes inside, and the reinforcing rod is slidably connected to the temporal part of the connecting hole, with the size of the reinforcing rod matching that of the connecting hole.

[0017] Compared with the prior art, this utility model provides an expansion joint for a labyrinth spherical double-compensation structure air supply device, which has the following beneficial effects:

[0018] The expansion joint of this maze-shaped spherical double-compensation air supply device uses a rotatable mounting ring installed on the outer peripheral wall of the base. The support ring is supported by the support seat and support rod, and the support ring supports two reinforcing rods, thereby effectively reducing the weight borne by the expansion joint. Moreover, the support ring can rotate and adjust its angle as the expansion joint rotates, without the need to disassemble and install the support structure, thus improving the convenience of use.
