Embodiment Construction

[0043] See Figure 1-2 , an ACP1000 anti-vibration bar assembly in this embodiment, comprising: an anti-vibration bar 1 with a V-shaped structure, and two end caps 2 fixedly sleeved on both ends of the anti-vibration bar 1 respectively, and each end cap 2 passes through multiple A positioning pin 3 or a screw is fixed on the end of the anti-vibration bar 1.

[0044] The end cap 2 and the anti-vibration strip 1 are provided with through holes suitable for matching with the positioning pin 3 .

[0045] Or the ends of the end cap 2 and the anti-vibration bar 1 are provided with threaded holes that are threadedly engaged with the screws.

[0046] The two ends of the anti-vibration strip 1 are rectangular, and the rest are tubular. The four sides of the rectangular part are provided with chamfers, and the end cap 2 is provided with a rectangular groove matching the rectangular part, so that the end cap 2 When being sleeved, it is only limited to the end, which is convenient for i...

Abstract

The invention relates to an anti-vibration strip assembly for an ACP1000 nuclear power station and a production method thereof. The anti-vibration strip assembly comprises an anti-vibration strip which has a V-shaped structure, and two end caps which fixedly sleeve two ends of the anti-vibration strip, wherein each end cap is fixed on the end of the anti-vibration strip through a plurality of positioning pins or screws. The anti-vibration strip assembly has a simple structure, and furthermore the product quality of the anti-vibration strip assembly satisfies a precise requirement for the anti-vibration strip by a stream generator in the nuclear power station, thereby realizing higher safety in use. According to the production method of the anti-vibration strip assembly, through a strict preparation process, the process requirement for the anti-vibration strip assembly of the steam generator in the nuclear power station is satisfied, thereby ensuring high quality and improving safety. The positioning pins are added on the end cap so that pulling separation of the end cap is prevented in an assembling process between the anti-vibration strip assembly and a U-shaped pipe.

Description

technical field [0001] The invention designs an anti-vibration bar assembly for an ACP1000 nuclear power plant and a production method thereof. Background technique [0002] The U-shaped heat transfer tube in ACP1000 of the domestic third-generation pressurized water reactor nuclear power plant is the most critical and weakest link in the pressure boundary of the primary circuit system. Once the heat transfer tube is damaged by vibration, the steam generator must be replaced, which will inevitably cause a huge waste of manpower, financial resources and incidents, and also increase the risk of radioactive radiation for maintenance personnel. Therefore, solving the steam generator tube failure accident is a key issue related to the safety of the nuclear power plant and to make the nuclear power plant competitive and viable. [0003] In order to eliminate the source of vibration as much as possible, it is generally necessary to install an anti-vibration strip assembly (ie ACP1...
