Anti-vibration bar structure of nuclear power plant steam generator

The invention discloses an anti-vibration bar structure of a nuclear power plant steam generator. The structure comprises at least two sets of anti-vibration bar assemblies installed on bent pipe sections of heat transfer pipes, retaining bars for limiting the anti-vibration bar assemblies from moving in the radial direction, and anti-deviation assemblies for preventing the anti-vibration bar assemblies from deviating. The anti-vibration bar assemblies are connected together through the anti-deviation assemblies. Compared with the prior art, according to the anti-vibration bar structure of the nuclear power plant steam generator, the independent anti-vibration bar assemblies are connected together through the anti-deviation assemblies, and the rotation and deviation prevention ability of anti-vibration bars is improved. 本发明公开了种核电厂蒸汽发生器防振条结构，其包括至少两组安装在传热管弯管段的防振条组件、限制防振条组件相对弯管段径向移动的保持条和防止防振条组件旋转偏移的防偏移组件，防偏移组件将各组防振条组件连接在起。与现有技术相比，本发明核电厂蒸汽发生器防振条结构利用防偏移组件将各组相对独立的防振条组件连接在起，增加了防振条的抗旋转偏移能力。
