Description

Technical Field

[0001] This utility model relates to the field of pipe clamp technology, and in particular to a pipe clamp suitable for viscous dampers in high-temperature and high-pressure petrochemical pipelines. Background Technology

[0002] Pipe clamps are common tools used to secure pipes or pipelines, ensuring their stability and safety. Because they are typically made of metal, pipe clamps are characterized by high strength, corrosion resistance, and high-temperature resistance, making them widely used in industries such as chemical, petroleum, and natural gas. However, high-temperature and high-pressure pipelines, due to the high temperature and pressure of the transported media, present one of the most challenging areas in industrial production, both in design and construction. The fixing and support of high-temperature and high-pressure pipelines mainly employs traditional fixed pipe clamps and spring supports. Previously, designers frequently used traditional fixed pipe clamps and spring supports for fixing high-temperature and high-pressure pipelines. However, because traditional fixed pipe clamps provide a constant constraint force, significant temperature changes often occur in the pipeline during the start-up and shutdown of petrochemical plants due to the flow of the internal medium, leading to a certain degree of thermal expansion. This thermal expansion of the pipeline, when encountering fixed constraints, poses a serious safety hazard. With societal development, designers have begun to incorporate spring supports for fixing and supporting some high-temperature and high-pressure pipelines. While spring supports can provide relatively variable support force based on the thermal expansion of the pipeline, the nature of elasticity means that spring supports can only withstand loads in one direction. However, pipeline vibration exists in all three directions. If the designer lacks design experience or makes mistakes in the pipeline stress calculation process, the spring support may overturn, leading to a safety accident.

[0003] Existing technology, such as Chinese Patent Publication No. CN106051309A, discloses an impact-resistant pipe support, including an upper pipe clamp, a lower pipe clamp, and a damping device. The upper and lower pipe clamps are combined into a circular, elliptical, or square shape to fix the pipe. Both ends of the upper and lower pipe clamps have clamping ends that extend radially outward. The upper and lower pipe clamps are connected by fasteners and nuts provided at their clamping ends. A washer is also provided between the clamping ends of the upper and lower pipe clamps. A base is provided on the top of the upper pipe clamp, and a damping device with an internal structure is fixedly connected to the base.

[0004] The aforementioned patent uses a damping device for shock absorption. The main structure of the damping device is a spring. After prolonged use, the spring is prone to losing its relaxation, which affects the shock absorption effect and thus the stability of the pipeline. Utility Model Content

[0005] The present invention proposes a viscous damper pipe clamp suitable for high-temperature and high-pressure petrochemical pipelines, which solves the problem of side rollover and increases the stability of the pipeline.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A viscous damper clamp suitable for high-temperature and high-pressure petrochemical pipelines includes a connecting device and a damping device. The pipeline is fixed on the connecting device, and the connecting device is connected to the damping device. The installed damping device is located at the bottom of the pipeline or on both sides of the pipeline. The damping device is sealed and filled with a viscous fluid.

[0008] The preferred embodiment of this utility model is that the connecting device includes a connecting platform and fasteners, and the pipe is fixed on the connecting platform by the fasteners.

[0009] The preferred technical solution of this utility model is that the connecting device includes a connecting platform, a connecting pipe and fasteners. The pipe is fixed on the connecting platform by the fasteners.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention proposes a viscous damper clamp suitable for high-temperature and high-pressure petrochemical pipelines. By adding a viscous damping device to a traditional clamp, it utilizes the characteristics of viscous fluids to effectively suppress multi-directional vibrations in the pipeline, providing variable constraint force without being limited by single-directional loads, thus greatly improving the safety and reliability of high-temperature and high-pressure pipelines. Especially during the start-up and shutdown of petrochemical plants, the viscous damper clamp can effectively absorb and disperse vibration energy caused by temperature changes due to the flow of the medium inside the pipeline, avoiding safety hazards caused by thermal expansion.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-3 As shown, this utility model provides a viscous damper pipe clamp suitable for high-temperature and high-pressure petrochemical pipelines, including a connecting device 1 and a damping device 2. The pipeline 3 is fixed on the connecting device 1, and the connecting device 1 is connected to the damping device 2. The installed damping device 2 is located at the bottom of the pipeline 3 or on both sides of the pipeline 3. The damping device 2 is sealed and filled with viscous fluid. Through the viscous fluid, the multi-directional vibration of the pipeline 3 is effectively suppressed, which solves the problems of traditional fixed pipe clamps and spring supports.

[0026] The damping device 2 is internally sealed and filled with a viscous fluid, and it also has a filling port 201 for this fluid. The selection of the viscous fluid is crucial; commonly used viscous fluids include silicone oil and mineral oil. These fluids have high viscosity and good chemical stability, allowing for long-term use under high temperature and high pressure environments without failure. The filling port 201 facilitates the addition and replacement of the viscous fluid, improving maintenance convenience.

[0027] Example 1

[0028] The connecting device 1 includes a connecting platform 101 and fasteners. The pipe 3 is fixed to the connecting platform 101 by the fasteners. The structure of the connecting platform 101 is the same as that in the previous embodiment, that is, it has an arc-shaped support 103 at the top and ear plates 104 on both sides. The fasteners are still in the form of U-bolts 106 and nuts 107 to ensure the pipe 3 is firmly fixed.

[0029] The top of the connecting platform 101 is provided with an arc-shaped support 103 for placing the pipe 3. The two sides of the connecting platform 101 are provided with ear plates 104, and the ear plates 104 are provided with fixing holes 105. The pipe 3 is fixed on the arc-shaped support 103 after passing through the fixing holes 105 with fasteners.

[0030] Ear plates 104 are disposed on both sides of the bottom of the arc-shaped support 103. Ear plates 104 include connecting plates and base plates. The connecting plates are disposed on both sides of the base plate and are respectively connected to the arc-shaped support 103 and the connecting platform 101. Fixing holes 105 are formed on the base plate. This structural design makes the entire connecting device 1 more stable and reliable, and also facilitates installation and disassembly.

[0031] The fasteners include U-bolts 106 and nuts 107. The pressure on the pipe 3 can be adjusted by adjusting the tightness of the nuts 107, ensuring that the pipe 3 is securely fixed to the connecting platform 101. Alternatively, other types of fasteners, such as clamps, can be selected to suit different application scenarios.

[0032] The damping device 2 is in direct contact with the connecting platform 101, which transfers the vibration energy of the pipe 3 to the viscous fluid, making it suitable for applications with small vibration amplitudes. By simplifying the connecting device 1, the number of parts is reduced, lowering manufacturing costs, while still effectively absorbing and dispersing the vibration energy of the pipe 3. It is especially suitable for low vibration amplitude applications. Even without the connecting pipe 102 in Embodiment 2, the viscous fluid within the damping device 2 can still provide some vibration reduction, ensuring the basic stability and safety of the pipe 3.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the connecting device 1 further includes a connecting pipe 102. One end of the connecting pipe 102 is connected to the connecting platform 101, and the other end of the connecting pipe 102 is located in the viscous fluid of the damping device 2. The connecting pipe 102 and the damping device 2 are sealed together, so that when the pipe 3 vibrates, it can transmit vibration energy to the viscous fluid through the connecting pipe 102, thereby achieving the vibration reduction effect.

[0035] When the connecting platform 101 is connected to the damping device 2 via the connecting pipe 102, a sealing ring 4 is provided between the connecting pipe 102 and the damping device 2. The function of the sealing ring 4 is to prevent leakage of viscous fluid and maintain the normal working condition of the damping device 2.

[0036] Example 3

[0037] Damping devices 2 are connected to both sides of the connecting platform 101. This dual-sided arrangement not only provides more uniform support but also better disperses the vibration energy of the pipe 3, improving the overall vibration reduction effect. Furthermore, if one side of the damping device 2 fails, the other side can still function, increasing the system's redundancy and reliability.

[0038] Example 4

[0039] The difference between this embodiment and Embodiment 3 is that a damping device 2 is arranged only on one side. This single-sided arrangement is suitable for situations with limited space or specific applications, such as installing a pipe 3 in a narrow space. Although there is only one damping device 2, it can still effectively absorb and disperse the vibration energy of the pipe 3 because it is filled with viscous fluid.

[0040] The connecting platform 101 has ear plates 104 on both sides. One ear plate 104 has a fixing hole 105 for fixing fasteners. The other ear plate 104 is a spare and can be used for additional reinforcement when necessary, increasing the flexibility of use.

[0041] Working principle

[0042] A viscous damper clamp suitable for high-temperature and high-pressure petrochemical pipelines fixes the pipeline 3 to the connecting platform 101 by U-bolts 106, thereby connecting the damping device 2. The damping device 2 is connected to the ground or steel structure foundation. When the pipeline 3 vibrates or has large thermal expansion, the damping device 2 provides viscous force to prevent the pipeline 3 from moving relative to the ground.

[0043] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
