Problems solved by technology
This type of high-frequency vibration has the characteristics of small vibration amplitude, high frequency and wide frequency band distribution, which often leads to vibration fatigue fracture of the attached small-sized pipeline
At present, hydraulic dampers, viscous dampers and other damping devices are widely used in the field of pipeline vibration control, which have a significant effect on low-frequency vibration control of pipelines, but are not suitable for high-frequency vibration control.
Moreover, in the prior art, there is no technical solution for adjusting the position of the pipeline while damping the vibration of the pipeline

Embodiment
[0023] Embodiment Pipeline damping adjustment device
[0024] Refer to attached Figure 1-3 , the pipeline damping adjustment device of the present embodiment is suitable for damping and adjusting the pipeline to be measured 15 subordinate to the main pipeline (the size of the pipeline to be tested 15 is smaller than the main pipeline 16), including a displacement measuring mechanism 13, a restraint mechanism 14 and the control mechanism 12 for collecting the signal of the displacement measuring mechanism 13 and controlling the action of the constraint mechanism 14 based on the signal. The displacement measurement mechanism 13 is used to measure the displacement of the pipeline 15 to be tested, and converts the displacement into a signal and transmits it to the control mechanism 12. The instruction of the pipeline 15 to be tested is adjusted.
[0025] Wherein, the displacement measurement mechanism 13 includes a base 8, a column 10 arranged on the base 8, a contact block 11 ...

The invention discloses a pipeline damping adjustment device, which includes a displacement measuring mechanism, a restraint mechanism and a control mechanism for collecting signals of the displacement measuring mechanism and controlling the action of the restraining mechanism based on the signals. The displacement measuring mechanism It includes a contact block in contact with the pipe, a displacement sensor for measuring the displacement of the contact block, and the restriction device includes a fixed block for fixing the pipe and a moving component for controlling the movement of the fixed block. The pipeline damping adjustment device of the present application has a reasonable structural design, can provide near-fixed restraint, effectively prevent vibration energy from being transmitted to downstream pipelines, reduce the vibration amplitude and vibration alternating stress of small-sized pipelines, and avoid vibration at its structurally weak positions Fatigue fracture; at the same time, it can adapt to the thermal expansion displacement caused by the high-temperature medium inside the main pipeline and small-sized pipeline.
Description
technical field [0001] The invention belongs to the technical field of pipeline adjustment, and in particular relates to an adjustment device suitable for high-temperature pipelines. Background technique [0002] There are a large number of pipelines in energy and chemical companies, which are responsible for the transmission of high-temperature media, and the flow rate of the internal media is often high. Due to the features of function and site layout, the section of some pipelines often changes (such as regulating valves and elbows); when high-speed medium flows through the section and changes the position, the stable medium may be disturbed, impacting the outer wall of the pipeline and causing high-frequency vibration of the pipeline. This type of high-frequency vibration has the characteristics of small vibration amplitude, high frequency and wide frequency band distribution, which often leads to vibration fatigue fracture of the attached small-sized pipeline. At prese...
