Abstract

The invention discloses a flaw detection device with a thickness measuring function of an inner hole of a heat conduction tube of a nuclear power evaporator. A first concave tabletop and a second concave tabletop are formed in the side surface of a column to form a base body; five through holes, namely two through holes I, two through holes II and a through hole III, are formed in the two concave tabletops in parallel; the axes of the two through holes I are intersected with each other on one side of the first concave tabletop and are both intersected with the axis of the base body; a plane in which the axes of the two through holes I are located is perpendicular to the first concave tabletop; the axes of the two through holes II are positioned on two sides of the axis of the base body and are in one same plane; the plane in which the axes of the two through holes II are located is perpendicular to the first concave tabletop; the axis of the through hole III and the axes of the through holes I are positioned in one same plane; the axis of the through hole III is perpendicular to the axis of the base body. The device can be used for detecting the inner hole in the axial direction, the circumferential direction and the thickness simultaneously, the problems that some flaw is neglected and cracks cannot be detected are avoided, the accuracy and the working efficiency of flaw detection are improved, and the flaw detection is reliable.

Description

technical field [0001] The invention relates to a flaw detection device for the inner hole of a heat transfer tube of a nuclear power evaporator with the function of measuring thickness. Background technique [0002] In recent years, nuclear power, as a highly efficient, clean and sustainable energy source, has been highly valued and widely concerned again. According to the current situation of the environment and the needs of sustainable development, nuclear energy has become one of the most practical and important alternative energy sources for ensuring energy supply security and adjusting the power structure in China, and is an important part of my country's modern energy industry construction. [0003] The steam generator is the hub of the first and second loops of the PWR nuclear power plant, the key equipment of the primary loop system, [0004] The main function is to generate high-quality dry steam through the heat exchange of the tube bundle, and drive the turbogen...
