【摘要】：本文研究了超超临界火电机组配套高低压旁路系统的结构形式、在机组启动、运行、停机过程中所起的作用、旁路系统容量的选择原则及控制的组成和作用。重点研究了高低压旁路系统配套阀门设计技术方案、高低压旁路阀的结构、实现减温减压的方式和原理，介绍了高低压旁路阀主要零部件的材料及选择原则，还研究了这新材料的化学成份及其各项力学性能。 本文还研究了高低压旁路阀门配套液动、电动和气动执行机构的调节控制精度、可靠性、操作力、快速开启关闭时间等性能的研究。
[Abstract]:In this paper, the structure form of high and low voltage bypass system for ultra supercritical thermal power unit is studied. The function of the system in start-up, operation and shutdown process, the selection principle of bypass system capacity and the composition and function of control are studied in this paper. The technical scheme of valve design for high and low pressure bypass system, the structure of high and low pressure bypass valve, the way and principle of reducing temperature and decompression, and the material and selection principle of main parts of high and low pressure bypass valve are studied emphatically. The chemical composition and mechanical properties of the new material were also studied. This paper also studies the control accuracy, reliability, operation force and quick opening and closing time of hydraulic, electric and pneumatic actuators of high and low pressure bypass valves.
