At present, some of the key valves used in large-scale nuclear power in China still rely on foreign imported valve brands, we all know that nuclear power plants refer to facilities that convert electrical energy through nuclear energy, using the heat generated by power reactors,To generate electricity, the key steam valves needed in the transformation process are dependent on foreign valve brands. The valves used in nuclear power are mainly high temperature and high pressure, and the pressure of steam valves designed and manufactured in China can reach 32.0MPa, the temperature can reach 650 degrees Celsius, but this is far behind foreign countries, the introduction of foreign technology is not not considered, just like the introduction of American ANSI standards, manufacturing pressure can reach 2500LB, 42.0MPa, barely,It can be used, but the reliability of this use is not high, after all, the technical temperature is not enough, the technical problems are improved, resulting in domestic independent production of valves but no one dares to use, domestic - some large valve companies have also been rejected Outside the door. At present, there are tens of thousands of domestic valve manufacturers, and there are few nuclear power standards that can really be achieved, and the market share of nuclear power valves is very large, only to break through the traditional manufacturing process, introduce talents, and further reduce nuclear power valves,To more effectively ensure its safety in order to truly reform the nuclear power valve industry in a new era, we need to introduce talents, whether domestic talents, or foreign, for our own design and construction belongs to Own nuclear power valve brand.
