Embodiment 1

[0027] Embodiment 1 The CAP1400 metal O-type sealing ring detection method of the present invention comprises the following steps:

[0028] 1) The system is full of water: inject distilled water into the water tank, and the water level of the distilled water reaches 2 / 3 or more of the height of the water tank;

[0029] 2) Low temperature full water: open the third valve and the fourth valve, close the fifth valve, turn on the secondary circuit pump to fill the steam generator with water;

[0030] 3) Temperature and pressure increase: Turn on the pipeline heating device and the steam generator to increase the temperature and pressure of the metal O-shaped sealing ring placed in the test bench in advance, and at the same time open the first valve, the second valve and the primary circuit pump until the test container The pressure and temperature of the inner cavity rise to the set value, where the pressure set value is 17.16MPa; the temperature set value is 360°C;

[0031] 4) H...

Embodiment 2

[0035] Example 2 The experimental platform constructed according to the method described in Example 1, comprising a test container 3, a pressurizer 6, a steam generator 9, a storage tank 11, a pipeline heating device 7 and a controller, the test container 3, the first pipe port of the steam generator 9 is respectively connected with the pipe mouth of the pressurizer 6 for the water inlet and outlet of the pressurizer 6 through a tee, and the pressurizer 6 The pipeline between the steam generator 9 is equipped with a pipeline heating device 7; the second nozzle of the steam generator 9 is connected with the water inlet pipeline of the primary circuit pump 16, and the outlet of the primary circuit pump 16 The water port is communicated with the water inlet pipeline of the test vessel 3; the test vessel 3, the pressurizer 6, the steam generator 9, the primary circuit pump 16 and the connecting pipeline therebetween constitute the first circulation loop ; Described test container ...

Abstract

A CAP1400 metal O-type sealing ring detection method and an experiment platform are disclosed. The method comprises: filling a system with water, performing low-temperature water filling, performing warm-keeping pressure reduction, performing warm-keeping pressure maintaining and performing temperature-decreasing pressure reduction, and detecting the heat-cold alternating performance of a metal O-type sealing ring after the above process is finished. Equipment constructed according to the above method comprises a test container, a voltage stabilizer, a steam generator, a water accumulation box, a pipe heating device and a controller; the controller comprises a signal acquisition module, a data processing module, a valve control module and an execution module; the test container, the voltage stabilizer, the steam generator, a first-loop pump and connection pipelines among the above devices form a first circulation loop; the steam generator, the water accumulation box, a second-loop pump and connection pipelines among the above devices form a second circulating loop; and the water accumulation box is provided with a third circulating loop. The beneficial effects comprise that the detection result is accurate, operation is simple, and man-made interference is small.

Description

technical field [0001] The invention relates to a detection method and an experiment platform for a CAP1400 metal O-shaped sealing ring, in particular to the performance measurement of a metal O-shaped sealing ring used for sealing an RPV flange of a reactor pressure vessel of a CAP1400 nuclear power plant. Background technique [0002] The full name of CAP1400 is "China's advanced passive nuclear power technology with an installed capacity of 1.4 million kilowatts with independent intellectual property rights." On the one hand, through re-innovation, a large-scale nuclear power technology brand with independent intellectual property rights has been formed. The preliminary design of China's third-generation nuclear power technology CAP1400 has passed the demonstration of the expert group organized by the National Energy Administration. The demonstration project is planned to start construction at the Shidaowan Nuclear Power Station in Weihai, Shandong in 2014, and it will be...
