Pipeline multidirectional vibration isolation device and nuclear power plant pressure pipeline

The invention provides a pipeline multidirectional vibration isolation device and a nuclear power plant pressure pipeline, the pipeline multidirectional vibration isolation device comprises an inner ring, an outer ring and a vibration isolation assembly arranged between the inner ring and the outer ring, a containing cavity is formed between the inner ring and the outer ring, the vibration isolation assembly is clamped in the containing cavity, and the pipeline penetrates through the inner ring; the vibration isolation assembly comprises a retainer and a rolling body arranged on the retainer, elastic vibration isolation layers are arranged on the end faces, facing the containing cavity, of the inner ring and the outer ring, and the two opposite ends of the rolling body make contact with the elastic vibration isolation layers. According to the multi-directional vibration isolation device for the pipeline, when the pipeline vibrates, the rolling bodies can move in the radial direction of the vibration isolation
