Description

Automatic sheet-distribution device inside the rectangular variable-section pipeline of nuclear power plants

technical field

The invention relates to the field of nuclear power detection equipment, in particular to an automatic sheet-distributing device inside a rectangular variable-section pipe of nuclear power.

Background technique

The longitudinal section of the nuclear power rectangular variable-section pipeline is shown in Figure 1. It is a double-layer D-shaped section. Its transverse section is shown in Figure 2. It consists of an outer shell, an inner shell, ribs and a compensation ring. The distance between the shell and the outer shell is between 180 and 280mm. With the change of curvature, the distance between the two ribs is 300mm. The width of the compensation ring is 200mm and the thickness is 50mm. Two longitudinal welds I and II are formed by welding between the inner shell and the inner shell. , the compensation ring itself is also made by tailor-welding multiple plates to form a transverse weld III. After all welding is completed, a closed space with a rectangular cross-section is formed. A section of compensation ring is used as a detection window for equipment to enter and exit before welding is completed. Due to structural limitations, the three welds can only be welded from the outer side of the inner shell to the side of the enclosed space, resulting in the surface of the welds on the side of the enclosed space being untreated and uneven.
