Key technologies of valves in China's nuclear power plants need to be broken through
At present, some key valves used in China's large-scale nuclear power still rely on imported valve brands. We all know that nuclear power station refers to the facilities that convert electric energy through nuclear energy, and use the heat generated by power reactor to generate electricity. The key steam valves needed in the process of transformation all rely on foreign valve brands. The valves used in nuclear power plants are mainly high temperature and high pressure. At present, the design and manufacture pressure of steam valves in China can reach 32.0mpa and the temperature can reach 650 ℃. However, this is far behind foreign countries. It is not without consideration to introduce foreign technology. Just like the introduction of American ANSI standard, the manufacturing pressure can reach 2500lb and 42.0mpa, which can barely be used. However, the reliability of this use is not high, so it is worth mentioning However, the technical heat is still not enough, and the technical problems have been improved. As a result, no one dares to use the domestic independently produced valves, and some domestic large-scale valve enterprises have been turned away. At present, there are tens of thousands of domestic valve manufacturers, but few of them can really meet the nuclear power standards. The market share of nuclear power valves is very large. Only by breaking through the traditional manufacturing process, introducing talents, further reducing the construction cost of nuclear power valves, and more effectively ensuring its safety, can we really reform the new era of nuclear power valve industry. We need to introduce talents, whether domestic talents Or abroad, for our own design and construction of nuclear power valve brand.
