摘　　要：低温恒温器安全阀和爆破片动作引起的低温系统故障对ADS注入器II直线加速器的运行效率和维护成本造成了较大影响。自行研制的多路调节阀手动控制器在不改变现有低温控制系统的前提下,实现了低温恒温器回气阀的冗余控制。通过运用独立失效可靠性模型,定性和定量分析改造前后低温恒温器控制的可靠性变化,证明低温恒温器控制可靠性得到了提高。该技术路线对CiADS低温控制系统的可靠性设计有借鉴意义。The failure of cryogenic system caused by the action of cryomodule safety valve and bursting disc has a great influence on the efficiency and cost of ADS injector Ⅱ linac operation and mainenance.The self-developed manual controller of multi-channel regulating valve realized the redundant control of cryomodules return valve without changing the existing cryogenic control system.By using the independent failure reliability model,the reliability changes of cryomodules control before and after upgrading were qualitatively and quantitatively analyzed.It is proved that the control reliability of cryomodules is improved.This technical route can be used for reference in reliability design of CiADS cryogenic control system..
