The "nuclear pneumatic actuator" developed by "Yang Xiu" won the gold award of the 9th International Invention Exhibition

"Yang Xiu" stood out among many projects and won the Gold Award. This equipment has the function of passive safe position reset, that is, in case of accident or failure, loss of power or gas source in the nuclear power plant, the actuator can automatically return to the safe on/off position without manual intervention, so as to reduce the risk of nuclear accident. The "nuclear pneumatic actuator" developed by "Yang Xiu" won the gold medal in the 9th International Invention Exhibition The 9th International Invention Exhibition, sponsored by the International Federation of inventors' associations (IFIA), supported by the State Intellectual Property Office, Jiangsu Provincial Department of science and technology, and Jiangsu Provincial Intellectual Property Office, and organized by Jiangsu Invention Association, Kunshan Municipal Bureau of science and technology, and Intellectual Property Office, was held in Kunshan International Convention and Exhibition Center from November 17 to 20, 2016

the participants of "Yang Xiu" stood out among many projects and won the Gold Award. This equipment has the passive safe position reset function, that is, when the nuclear power plant has an accident or failure, or loses power or gas supply, the actuator can automatically return to the safe on/off position without manual intervention, so as to reduce the harm caused by the nuclear accident

nuclear grade valves are mainly used in the containment of nuclear power plant reactors. By cutting off or connecting pipelines, they assume the safety function of the system and play a key role in the safety of nuclear reactor operation. Before 2006, among the major nuclear power plants in China, domestic valves accounted for only about 4% of the total valves, all of which were nuclear grade II and III, and 96% of which were imported

the nuclear power plant can use the whole length of the saw blade to avoid the risk of radioactive radiation. In order to effectively control the damage of radioactive radiation to the operation and maintenance personnel and improve the automation level of the operating unit, a large number of nuclear level valves that can be remotely controlled are selected in the design. The opening and closing of these valves are controlled by the buttons in the main control room to meet the needs of system operation. Nuclear grade valves are used in a large number of medium transmission control equipment in nuclear power plants, and they are an essential part of the safe operation of nuclear power plants. Nuclear level actuator is the driving mechanism of nuclear level valve and an important equipment related to the performance of nuclear level valve. It can be said that without the autonomy of nuclear level actuator, it is impossible to truly realize the autonomy of nuclear level valve. The "nuclear pneumatic actuator" developed by the company breaks the monopoly of foreign enterprises in the technology and price of nuclear valve products according to different samples and experimental power, and gets rid of the dependence of domestic valve enterprises on foreign products. At the same time, the autonomy of "nuclear pneumatic actuator" is also conducive to the technological progress of domestic enterprises. It can be seen that the autonomy of nuclear actuator is of great significance

our company is the earliest and largest professional design manufacturer of actuator in China, and one of the earliest manufacturers in China to develop pneumatic actuator for nuclear power. As the "nuclear pneumatic actuator" has severe operating conditions and special requirements for supporting parts, it took the enterprise 5 years to develop and produce the first pneumatic actuator for nuclear power. In september2012, entrusted by the national energy administration, China Machinery Industry Federation organized the "million kilowatt nuclear power nuclear pneumatic actuator engineering prototype appraisal meeting" in Yangzhou. Field experts agreed that the million kilowatt nuclear power nuclear power diaphragm pneumatic actuator engineering prototype was successfully developed, which achieved a new breakthrough in the localization of nuclear pneumatic actuator, filled the domestic gap and reached the international advanced level. At present, the product has been used in many domestic nuclear power plants

insiders believe that the successful development of the "nuclear pneumatic actuator" and mastering its key design and manufacturing technology are of positive significance to accelerate the realization of the goal of localization of nuclear valves and the process of localization of nuclear power units, reduce the dependence on and import of similar foreign products, and help to improve the automatic control level of nuclear power units, so that the unit can operate safely under the condition of small deformation. Moreover, at present, the price of this foreign component is high, and localization has greatly saved the cost
