发布时间：2018-09-12 13:06
【摘要】：液动自力式(介质驱动)高加(高压加热器简称高加)三通阀组是“超(超)临界火电机组关键阀门国产化”研发项目中第二类关键阀门,主要应用在电厂给水循环加热管路系统中,主要功能是将高加从管路系统中解列出来,从而实现保护和在线维修高加的作用。液动(自力式)入口三通阀+液动(自力式)出口三通阀阀组因为在整体系统设计方面、技术突破、使用性能及经济效益方面均具有优势,是超(超)临界火电机中高加三通阀组的最佳选择方案。到目前为止,液动自力式(介质驱动)高加三通阀组主要依靠国外进口。对于超(超)临界火电机组关键阀门中的液动自力式(介质驱动)高加三通阀组的研发,已经成为我国火电机组发展过程中必须要解决的关键问题。论文中阐述了液动自力式(介质驱动)高加三通阀组开发过程；详细描述了针对高温、高压、大口径、高性能等工况和要求特点,综合应用控制技术,液压传动技术,流体动力学等现代设计技术和多专业的相关知识,研究了整体方案的设计、三通阀门的结构、驱动机构、主体材料、制造和装配工艺等具体内容；对产品的设计和性能进行了设计计算及有限元分析；通过样机试制、试验检验对产品的设计进行确认。开发过程充分体现了现代设计方法在产品设计过程中的重要作用,大大的提高了产品设计的可靠性和成功率,并且起到了缩短研发周期和降低研发成本的作用。产品已经通过业内专家的鉴定,并且具备市场推广及销售条件。论文对类似产品的研发有重要的参考价值。
[Abstract]:The three-way valve set of hydrodynamic self-driving (medium driven) high additive (high pressure heater) is the second kind of key valve in the research and development project of "key valves of supercritical thermal power unit". It is mainly used in the power plant water supply cycle heating pipeline system, the main function is to remove the high addition from the pipeline system, so as to realize the function of protection and online maintenance. Hydraulic (self-operated) inlet three-way valve, hydraulic (self-propelled) outlet three-way valve set has advantages in overall system design, technical breakthrough, performance and economic benefits. It is the best choice of high-and three-way valve set in super (supercritical) fire motor. So far, the hydraulic self-drive (medium-driven) high-pass valve group mainly depends on foreign imports. The research and development of hydrodynamic self-actuated (medium driven) high add three-way valve set in the key valve of supercritical thermal power unit has become a key problem that must be solved in the development process of thermal power unit in China. In this paper, the development process of hydraulic self-actuated (medium driven) high-add three-way valve group is described in detail, and the comprehensive application of control technology and hydraulic transmission technology is described in accordance with the characteristics of high temperature, high pressure, large caliber, high performance and other working conditions and requirements, such as high temperature, high pressure, large caliber, high performance and so on. Fluid dynamics and other modern design technology and multi-professional knowledge, studied the overall design, three-way valve structure, driving mechanism, main materials, manufacturing and assembly process and other specific content; The design calculation and finite element analysis of the design and performance of the product are carried out, and the design of the product is confirmed by the trial production of the prototype and the test. The development process fully reflects the important role of modern design methods in the process of product design, greatly improves the reliability and success rate of product design, and plays a role in shortening the R & D cycle and reducing R & D costs. The product has passed the appraisal of the industry expert, and has the market promotion and the sale condition. The paper has important reference value for the research and development of similar products.
