Nuclear power pneumatic valve working conditions

nuclear power pneumatic valves in addition to its working environment is complex, the medium temperature, pressure and radioactivity level of rigour is also very special.
nuclear power transmission medium pneumatic valve are mainly: saturated steam and condensate, radioactive steam heavy water, corrosive, radioactive irradiation, dilute sulphuric acid and alkali medium, carbon dioxide, sodium, helium, oil, vacuum and other fluid medium.
once the drift diameter pneumatic valve working conditions on the road is the most complex, in the present stage of nuclear power plant steam parameters than the thermal power plant steam parameters ( Pressure. MPa, temperature ℃) Lower, but the nuclear power plant operating conditions is much more complicated. In the liquid metal fast neutron reactor coolant device, steam parameter as the highest ( The temperature of the steam turbine before for ℃, the pressure is zero. MPa） 。
