A high temperature pipeline protection device

Abstract

The invention discloses a high-temperature pipe protection device, and relates to the field of vibration relief and impact protection of high-temperature pipes. The high-temperature pipe protection device comprises a shell, an energy absorbing component, a high-temperature pipe limiting component, a fixing component and a pressure adjusting mechanism, wherein accommodating space is formed in the shell, and is filled with particles; the energy absorbing component is at least partially embedded in the particles, and is provided with multiple small holes for enabling the particles to pass through when the energy absorbing component and the shell are relatively vibrated; the high-temperature pipe limiting component is connected with the shell or the energy absorbing component; the fixing component is connected with one of the shell and the energy absorbing component not connected with the high-temperature pipe limiting component; and the pressure adjusting mechanism is used for adjusting the compaction degree of the particles in the accommodating space. In vibration displacement, the particles are vibrated and rubbed to consume the vibration energy; the particles flow to pass through the small holes; the moving space of the energy absorbing component is cleared to guarantee relative displacement; and during impacting, the particles are adjusted by the pressure adjusting mechanism to tightly bond on the shell and to tightly wrap hole-carried objects to form fixing structures, so that activities of the high-temperature pipes are limited, and the impact damage is reduced.

Description

technical field [0001] The invention relates to the field of vibration mitigation and impact protection for high-temperature pipelines, in particular to a high-temperature pipeline protection device. Background technique [0002] High-temperature pipelines such as steam high-temperature pipelines are indispensable components in ship power plants, and are used for working medium transportation and energy transmission between various equipment. [0003] During the use of high-temperature pipelines, when the working conditions are switched, the temperature in the high-temperature pipelines changes greatly, which will cause the secondary stress of the high-temperature pipelines to exceed the standard. In order to avoid this situation, high-temperature pipelines generally use multiple elbows to set It forms a complex space structure, and adopts the support method of fixed ends and elastic support in the middle, so that the high-temperature pipeline has greater flexibility and sel...

Problems solved by technology

[0005] Since a single hydraulic damper can only prevent impact damage in one direction, it is necessary to arrange multiple hydraulic dampers on the high-temperature pipeline system to improve the overall impact resistance of the system. However, due to the large volume of the hydraulic damper, the cost Expensive, therefore, the use of multiple hydraulic dampers is not only costly, but also requires a lot of space resources in the ship
