摘要
真空室作为托卡马克核聚变装置的关键部件之一,为等离子体提供高真空运行环境。为了避免冷却剂泄漏等事故造成的增压损伤真空室及其内部组件,需配备相应的真空室超压保护系统,泄压阀是其中的关键部件。基于系统功能要求和电磁阀工作原理,提出了一种新型的电磁泄压阀,该阀门属于自动阀门,不需要额外的控制系统,可实现快速泄压。本文首先介绍了电磁泄压阀的结构设计和工作原理,最后利用ANSYS软件研究波纹管的弹性特性,为阀门的制造和测试提供技术参考。
The Vacuum Vessel provides a high vacuum environment for the operation of plasma, as one of the most important components in tokamak fusion device. An overpressure protection system should be installed for Vacuum Vessel to prevent itself and inner components from overpressure damages caused by the ingress of coolant events and one of the key components of which is the relief valve. In this paper, a new electromagnetic relief valve was proposed based on the system functional requirements and working principle of electromagnetic valves. This valve is an automatic device and could release pressure rapidly without extra control systems. The structural design and operating principle of this valve were described firstly and then the elastic characteristics of bellows were studied with ANSYS software to provide technical reference for manufacturing and testing of the valve.
