Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel compensators, specifically a stainless steel compensator that prevents over-compensation and loosening. Background Technology

[0002] Stainless steel compensators are devices used in pipeline systems to absorb the expansion, contraction, and displacement of pipelines caused by factors such as temperature changes, pressure fluctuations, or external vibrations. They effectively reduce stress in pipeline systems, prevent pipeline rupture and deformation, and improve pipeline safety and stability. Made of stainless steel, compensators possess excellent corrosion resistance, high-temperature resistance, and pressure resistance, making them widely used in pipeline systems in petroleum, chemical, power, heating, air conditioning, and marine industries.

[0003] For example, a stainless steel flexible hose compensator with a supporting function, disclosed in CN217081846U, includes a stainless steel flexible hose compensator support device and a receiving frame. The bottom of the receiving frame is slidably sleeved on the outer surface of the stainless steel flexible hose compensator, and the upper part of the receiving frame is slidably sleeved on the outer surface of the support device. A support frame is fixedly installed inside the support device. Reinforcing ribs are symmetrically welded to the outer surfaces of both ends of the support frame. Limit plates are welded to the center of both end faces of the support frame, and a threaded rod is threadedly connected to the center of the top surface of the limit plate. By installing the support device and the receiving frame on the outer surface of the stainless steel flexible hose compensator, the middle part of the stainless steel flexible hose compensator can be easily supported, preventing the middle part of the stainless steel flexible hose compensator from sagging and exerting tensile force on the connection between the two ends of the pipeline, thereby effectively protecting the connection between the stainless steel flexible hose compensator and the pipeline.

[0004] The aforementioned patent proposes that by installing support devices and receiving frames on the outer surface of the stainless steel flexible hose compensator, the middle part of the stainless steel flexible hose compensator can be easily supported. However, in actual use, although the support devices and receiving frames can support the middle part of the stainless steel flexible hose compensator, they will restrict the compensator's free expansion and contraction and displacement capabilities. If the support devices are too tight or fixed, it will affect the normal operation of the compensator, reduce its compensation capacity, and even cause excessive stress concentration in other parts of the compensator, damaging the hose or pipeline. Utility Model Content

[0005] The purpose of this invention is to provide a stainless steel compensator that prevents overcompensation from loosening, so as to solve the problem of limiting the free expansion and contraction and displacement capacity of the compensator mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel compensator for preventing over-compensation loosening, comprising a compensator, with threaded holes A symmetrically opened on the outer side of one end of the compensator, a connecting hole through one end of the compensator, and a protective structure installed on the outer surface of the compensator; The protective structure includes an outer limiting member and a connecting member installed inside the connecting hole.

[0007] Preferably, the outer limiting member includes a connecting ring and an outer limiting ring installed outside the connecting ring, an inner connecting ring is installed on the outer side between the connecting ring and the outer limiting ring, and threaded holes B are symmetrically opened on the outer surface of the connecting ring, with anchor bolt bodies installed inside the threaded holes B.

[0008] Preferably, the connecting member includes a threaded rod and a connecting rod installed at one end of the threaded rod, and a threaded shaft is installed at one end of the connecting rod.

[0009] Preferably, an outer rotating bar is movably installed on the outer side of the connecting rod, and a threaded hole D is opened on the outer side of the outer rotating bar.

[0010] Preferably, a connecting strip is installed between the connecting ring and the outer limiting ring, and a side strip is installed on one side of the connecting strip, with a threaded hole C extending through the middle of the side strip.

[0011] Preferably, a bolt rod is threaded into the threaded hole C, and the lower end of the bolt rod is threaded into the threaded hole D.

After the compensator is aligned with other pipes, the mounting holes and connecting holes of the other pipes are aligned. The connecting components fix the compensator and the pipes. The threaded hole C is aligned with the threaded hole D. The bolt rod is turned into the interior of the threaded hole C and the threaded hole D to fix the external limiting component and the connecting component, thereby strengthening the connection between the compensator and the pipes. This makes the connection between the compensator and the pipes more secure and prevents loosening caused by load changes during long-term use. At the same time, the compensator can still maintain the compensation effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figures 1-4 A stainless steel compensator for preventing over-compensation loosening includes a compensator 1, with threaded holes A11 symmetrically opened on the outer side of one end of the compensator 1, a connecting hole 12 penetrating through one end of the compensator 1, and a protective structure 2 installed on the outer surface of the compensator 1.

[0018] The protective structure 2 includes an outer limiting member 21 and a connecting member 22 installed inside the connecting hole 12. The connecting member 22 has four sets.

[0019] The outer limiting member 21 includes a connecting ring 211 and an outer limiting ring 213 installed outside the connecting ring 211. An inner connecting ring 214 is installed on the outer side between the connecting ring 211 and the outer limiting ring 213.

[0020] The connecting member 22 includes a threaded rod 221 and a connecting rod 222 installed at one end of the threaded rod 221. A threaded shaft 224 is installed at one end of the connecting rod 222. The threaded shaft 224 and the threaded rod 221 can be threaded into the interior of the connecting hole 12.

[0021] An outer rotating bar 223 is movably mounted on the outer side of the connecting rod 222. A threaded hole D225 is opened on the outer side of the outer rotating bar 223. The length of the outer rotating bar 223 is consistent with the distance between the threaded rod 221 and the threaded shaft 224. The rotating outer rotating bar 223 facilitates the adjustment of the orientation of the threaded hole D225.

[0022] A connecting strip 215 is installed between the connecting ring 211 and the outer limiting ring 213. The connecting strip 215 supports the connection between the connecting ring 211 and the outer limiting ring 213. A side strip 216 is installed on one side of the connecting strip 215. A threaded hole C217 is opened through the middle of the side strip 216. The threaded hole C217 is aligned with the threaded hole D225. There are four sets of connecting strips 215, side strips 216 and threaded holes C217. The positions of the connecting strips 215 are aligned with the positions of the connecting strips 215. The threaded holes C217 are opened towards the center of the connecting ring 211.

[0023] The threaded hole C217 has a bolt rod 23 connected to its internal thread. The lower end of the bolt rod 23 is threaded into the threaded hole D225. The bolt rod 23 is used to fix the external limiting member 21 and the connecting member 22.

[0024] In this embodiment: After the compensator 1 is aligned with other pipes, the mounting holes of the other pipes are aligned with the connecting holes 12. The threaded shaft 224 first rotates into the interior of the connecting hole 12, and then into the mounting hole of the pipe. Subsequently, the outer rotating bar 223 enters the connecting hole 12 and the mounting hole. Then, the threaded rod 221 connects the compensator 1 and the pipe, and the connecting member 22 fixes the compensator 1 and the pipe. The outer rotating bar 223 rotates outside the connecting rod 222, causing the side of the outer rotating bar 223 with the threaded hole D225 to face the side bar 216. The threaded hole C217 is aligned with the threaded hole D225. The bolt rod 23 rotates into the interior of the threaded hole C217 and the threaded hole D225. The bolt rod 23 is used to fix the outer limiting member 21 and the connecting member 22, strengthening the connection between the compensator 1 and the pipe, making the connection between the compensator 1 and the pipe more secure, preventing loosening due to load changes during long-term use, while the compensator 1 can still maintain the compensation effect.

[0025] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4The outer surface of the connecting ring 211 is symmetrically provided with threaded holes B212. Anchor bolt bodies 24 are installed inside the threaded holes B212. The threaded holes B212 are aligned with the threaded holes A11. The anchor bolt bodies 24 can be threaded into the interior of the threaded holes A11. There is space between the connecting ring 211 and the outer limiting ring 213 to facilitate the disassembly and assembly of the anchor bolt bodies 24. The number of connecting holes 12 is greater than the number of connecting components 22 installed. Ordinary bolts are used to install the compensator 1 and the pipeline. The ordinary bolts are threaded into the remaining outer limiting components 21 and the mounting holes. When the protective structure 2 is replaced, the ordinary bolts can still maintain the connection between the compensator 1 and the pipeline.

[0026] In this embodiment: When installing the outer limiting component 21, the connecting ring 211 is wrapped around the outside of one end of the compensator 1, and the threaded hole A11 is aligned with the threaded hole B212. Holding the anchor bolt body 24, the threaded end of the anchor bolt body 24 is turned into the inside of the threaded hole B212 and the threaded hole A11, and the outer limiting component 21 is fixed to the outside of one end of the compensator 1. The compensator 1 and the protective structure 2 can be disassembled and assembled, which facilitates the replacement of the protective structure 2. The four sets of connecting components 22 can provide greater fastening force, and the force is distributed in different directions to avoid excessive concentrated pressure at the position, reduce the risk of excessive local stress, thereby improving the overall stability of the connection and making the connection more secure. Especially in high pressure or high temperature environments, it can ensure that the connection between the compensator 1 and the pipeline is more stable and avoid loosening due to vibration or temperature difference changes.
