Description
Technical Field
The utility model relates to a nuclear power overhauls technical field, specifically is a solenoid valve capability test system that is used for AP1000 main steam and main isolation valve of giving water.
Background
The main steam isolation valve of the domestic second-generation nuclear power station has the advantages that the main steam isolation valve is closed due to the internal leakage of main oil drainage electromagnetism; meanwhile, 90% of stroke tests cannot be carried out due to the fact that the main oil drainage electromagnetic valve and the test electromagnetic valve are refused to move. The reason for this is that the analysis is: when the electromagnetic valve is maintained, after the O-shaped ring is replaced, the spring force of the electromagnetic valve is set improperly in the assembling process, the electromagnetic valve fails to operate due to overlarge spring force, and the electromagnetic valve leaks due to undersize spring force.
A main steam isolation valve and a main water supply isolation valve of the AP1000 third-generation nuclear power station are manufactured by American flowerve company, are structurally gas-liquid linkage wedge-shaped gate valves, are the same as the main steam isolation valve of the domestic second-generation nuclear power station, and are very similar in valve structure. For the AP1000 main steam isolation valve and the main water supply isolation valve, the preventive maintenance period recommended in a manufacturer maintenance manual is 12 years, and the maintenance period recommended by the main steam isolation valve of the second-generation nuclear power in China is 3-5 years. In addition, according to experience feedback of second-generation nuclear power, after the electromagnetic valve on the main steam isolation valve breaks down for many times, the O-shaped ring is replaced every 2 years, and the electromagnetic valve is replaced every 4 years. The main oil drainage solenoid valve and the test solenoid valve on the main steam and the main water supply isolation valve are key sensitive and single-point failure components, if the solenoid valves leak in the power operation period, the main steam and the main water supply isolation valve are closed, and finally shutdown is caused; if the electromagnetic valves are refused to move or jammed when receiving PMS protection signals, the main steam isolation valve and the main water supply isolation valve cannot be closed within 5s, the requirements of technical specifications are broken through, and the safe operation of a power plant is threatened. And the preventive maintenance cycle of the electromagnetic valve on the AP1000 main steam and main water supply isolation valve is far longer than that of the valve in the second-generation nuclear power in China, so that the reliability of the electromagnetic valve is difficult to guarantee by the long pre-maintenance cycle, and therefore, the performance of electromagnetic valve spare parts to be installed on a system, the performance of the electromagnetic valve during operation and the performance of the electromagnetic valve after maintenance and renovation are required to be tested, and the reliable use of the electromagnetic valve during operation is guaranteed.
Because the pressure parameter and the power supply grade of the electromagnetic valve control system on the second-generation semi-nuclear power main steam isolation valve in China are much lower than those of the AP1000 main steam and main water supply isolation valve hydraulic control system, the test system of the main steam isolation valve in the second-generation nuclear power station in China is not suitable for the electromagnetic valve performance test of the AP1000 main steam and main water supply isolation valve.
