Nuclear power plant voltage stabilizer spray valve

The invention belongs to the technical field of nuclear power, and particularly relates to a nuclear power station voltage stabilizer spray valve. According to the spray valve, due to the fact that the through-flow sectional area of the valve element hole channel is far smaller than the through-flow sectional area of the valve when the opening degree is large, the valve element hole channel does not change the flow of the spray valve when the opening degree is large, and the original flow characteristic and control requirement of the spray valve can be effectively maintained; furthermore, the pore channel of the spray valve effectively avoids rapid change of a circulation gap caused by small change of the rotating angle of the valve core when the valve is closed, so that the rotating angle change caused by deviation, thermal expansion and the like of a valve transmission part does not obviously influence the medium flow and the temperature of the spray valve when the flow is small any more. Therefore, a stabl
