Description
Technical Field
The utility model belongs to the technical field of mechanical equipment, concretely relates to novel spacing fixture block of pipeline axial device of nuclear power plant.
Background
The working medium of the steam-water pipeline of the nuclear power plant is high-temperature steam, the temperature can reach more than 300 ℃ during working, and the temperature is about 25 ℃ at room temperature during non-working. The temperature difference of nearly 300 ℃ causes the pipeline to generate great stress when expanding with heat and contracting with cold, the stress generates potential safety hazards to interfaces and equipment on the upstream and downstream of the pipeline, and therefore the influence of pipeline expansion can be considered in the pipeline arrangement design and an axial limiting support is arranged.
However, the current horizontal axial limiting support of the steam-water pipeline for the nuclear power plant uses a traditional single-clamping block structure to transfer load. After the single clamping block generates fatigue deformation, axial limiting failure is directly caused, and the pipeline can generate thermal expansion displacement to influence the safety of an upstream interface, a downstream interface and equipment.
In view of the problems in the prior art, an improved pipeline axial limiting fixture block device is urgently needed to be designed, and the risk of fixture block failure is reduced.
