本次取得的许可证级别包含了除A2(2)外所有级别的调节阀的设计与制造，许可范围宽，产品空间大，市场前景广。压力管道元件（阀门）制造许可证的获取，同时也标志着我院战略重点基金项目——电站高端阀门国产化研究取得了阶段性成就。作为我院常规电能源领域技术创新目标的重要研发项目，该项目以超超临界火电机组关键调节阀为研制对象，研制包括二级过热器出口疏水阀、再热减温水调节阀、过热器减温水调节阀、高加疏水调节阀和最小流量阀等目前还依赖进口的高端调节阀。该项目通过对高温高压调节阀的结构设计、流量特性、关键零部件材料性能以及表面改质技术的运用等方面进行深入研究和产品试制，使我院具备了高端调节阀的生产能力，实现国产化替代。（制造技术研究所 张含、李连翠 ）
SAMR Issued Manufacture License of Special Equipment
(Pressure Piping Components) to SPERI
The Manufacture License of Special Equipment (Pressure Piping Components) has been issued by the State Administration for Market Regulation (SAMR) to SPERI on May 11, 2018. The license number is TS271020T-2022, and the license scope is the metal control valve in pressure piping with grades A1, A2(1), B1&B2. It is an important phase achievement for research and development of high-level valves in SPERI. SPERI obtains control valve design and manufacture authority which lays a solid foundation for the industrialization of high-level valves.
The license includes all grades of control valves except the A2(2)，which has wide permission range, large product space and broad market prospect. The acquirement of the license also marks a stage achievement in strategic emphasis fund project of SPERI named nationalization research of power station high-level valves. As a research and development project for the technical innovation target in the common electric power industry, the project chooses key valves in the ultra-supercritical power plants as its research objects, mainly include the secondary superheater outlet drain regulating valve, the attemperating water control valve in boiler reheater, the attemperating water control valve in boiler superheater, the high pressure heater drainage water control and the mini-flow valve, which still rely on import at present. Deeply researching for high temperature and high pressure valves on structure design, flow characteristics, the material properties for key parts and the application of surface modification technique are conducted, and prototypes of those valves are manufactured. The project ensures the capability in localized substitution of high–level control valves.
The successful execution of the nationalization research project base on the guidance of SPERI leaders, the Organization of Technology Management and Industrial Affairs Department, Power Equipment Products Business Department, and Manufacture Technology Institute, meanwhile, great support is gotten from Plan Development Department, Safety and Quality Department, Financial Development, HR Development and Dean Office. During the obtain of the license, SPERI passed evaluation in terms of the personnel qualification, resource conditions and quality assurance system by Special Equipment Safety Supervision Inspection Institute of Jiangsu Province, and gained accordant agreements and high commend by assessment specialists. It fully embodies SPERI’s exploitation and innovation, realistic and pragmatic work spirits. It also firms our confidence with brave exploration and sustainable development in a stormy market competition.
