[0002] Constant force spring supports and hangers can bear large loads and thermal displacements and are widely used in pipelines and equipment in the energy industry. Since their internal connection structures are all sliding friction, the increase in the fitting clearance caused by long-term active friction will directly cause external impurities to penetrate into the support and hanger, especially some water vapor and impure gases. Long-term retention in the support and hanger will cause corrosion and rust of the internal spring parts. Utility Model Content

[0015] The present invention will be described in further detail below with reference to the accompanying drawings.
[0016] Embodiment: An improved spring hanger, such as Figure 1 and Figure 2 As shown, it includes a bracket seat 1 and a pipe pressure-bearing member 2. The bracket seat 1 includes a mounting block 3 and a bracket sleeve block 4 vertically fixed to the mounting block 3. The mounting block 3 can realize the installation and fixation of the integral spring support bracket.
[0017] A telescopic cavity 5 is provided inside the bracket sleeve block 4, and a telescopic adjustment hole 6 is provided at the end of the telescopic cavity 5 away from the mounting block 3. The pipeline pressure-bearing member 2 includes a pressure-bearing rod 7 slidably plugged into the telescopic cavity 5 and a pipeline sleeve block 8 provided at the end of the pressure-bearing rod 7 extending out of the telescopic cavity 5. A compression block 9 is also provided at the end of the pressure-bearing rod 7 away from the pipeline sleeve block 8. The compression block 9 slides with the telescopic cavity 5, and a compression spring 10 is provided between the compression block 9 and the bottom of the telescopic cavity 5. The displacement of the pipeline part is transmitted through the pipeline pressure-bearing member 2. The action of the compression spring 10 can achieve buffering and release of the thermal displacement of the pipeline to ensure the stable position limit state of the pipeline.
[0018] Since existing spring hanger equipment is often used under relatively complex working conditions, it is easy for external water vapor and impurities to penetrate into the interior, causing rust and corrosion of the internal compression spring 10, especially in the contact gap between the pressure-bearing rod 7 and the telescopic adjustment hole 6. The opening of the telescopic adjustment hole 6 of the spring hanger is also provided with a rotating bearing block 11, which is rotatably connected to the opening of the telescopic adjustment hole 6. The middle part of the rotating bearing block 11 is provided with a threaded ring block 12 and a dust removal soft block 13. The pressure-bearing rod 7 is provided with a threaded section for the threaded ring block 12 to cooperate with. As the pressure-bearing rod 7 vertically displaces, the cooperation between the threaded ring block 12 and the threaded section drives the rotation of the rotating bearing block 11, and then the dust removal soft block 13 is used to clean impurities on the surface of the pressure-bearing rod 7, thereby reducing the mixing of impurities and improving the sealing performance of the fitting gap.
[0019] Because the compression block 9 in the telescopic chamber 5 can achieve telescopic sliding along the length of the telescopic chamber 5, a corrugated telescopic block 16 is also provided between the compression block 9 and the top of the telescopic chamber 5. The provision of the corrugated telescopic block 16 can further reduce the direct entry of a small amount of mixed impurities and water vapor into the compression spring 10 area, reducing the process of internal corrosion and aging. Multiple drain valve blocks 14 are also provided at the bottom of the bracket sleeve 4, and wear-resistant sealing blocks 17 are provided on the sides of the compression block 9. The drain valve blocks 14 can automatically open and exhaust when the internal gas is compressed to a certain pressure. The multiple drain valve blocks 14 have different specifications and can adapt to different instantaneous internal pressures to ensure a stable and sufficient compression and exhaust process for impurities and water vapor.
[0020] To ensure a stable airflow path for the drain valve block 14, a stepped groove 15 is provided at the bottom of the mounting block 3, connecting to multiple drain valve blocks 14 and ensuring a stable and reliable exhaust flow path. Furthermore, an auxiliary groove 18 is provided in the middle of the pressure-bearing rod 7, and an auxiliary guide block 19 is provided at the bottom of the expansion chamber 5, which cooperates with the auxiliary groove 18. The cooperation between the auxiliary groove 18 and the auxiliary guide block 19 improves the vertical pressure-bearing movement of the pressure-bearing rod 7 during the expansion and contraction of the compression spring 10.
[0021] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
