Abstract

The invention provides a water seal device of a nuclear power station voltage stabilizer. The water seal device comprises a connecting pipe, a safety pipe, an elbow, a heat preservation layer and a safety valve, wherein the safety pipe and the elbow are connected to the two ends of the connecting pipe respectively and communicate with the connecting pipe, the connecting pipe and part of the safety pipe are sleeved with the heat preservation layer, and a safety valve is fixedly connected with and communicates with the end, far away from the connecting pipe, of the safety pipe; a first channel is arranged in the connecting pipe, a second channel is arranged in the safety pipe, a third channel is arranged in the elbow, a fourth channel is arranged in the safety valve, and the first channel, the second channel, the third channel and the fourth channel correspond and communicate to form a water seal channel; part of saturated steam in the water seal channel is liquefied when meeting cold after passing through the safety valve and part of the safety pipe, and condensate water is accumulated at the elbow and used for blocking the water seal channel. Compared with the prior art, the water seal device of the nuclear power station voltage stabilizer is simple in structure, high in water seal efficiency and capable of saving space.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a water seal device for a voltage stabilizer of a nuclear power plant. Background technique [0002] The pressurizer is one of the key equipment of the PWR nuclear power plant. It regulates and controls the pressure and volume of the main system of the primary circuit, and plays a very important role in ensuring the integrity of the pressure boundary of the main system of the primary circuit. [0003] The change of the oxygen content in the loop water directly affects the chemical reaction rate of the loop water, impurities in the water and metals. When the nuclear power unit is in normal operation, the hydrogen content in the loop water reaches a certain concentration by filling the capacity control box with hydrogen, so as to inhibit the generation of oxygen by water irradiation, thereby inhibiting the chemical reaction rate of the loop wate...
