Abstract

This invention relates to one nuclear power stabilizer wave tube weld beam test and position device, which comprises double slide entrance hole supportive position rack on the flange surface, wherein, the position rack comprises entrance hole flange connection socket with double slide set and flexible cover tube in between with radio source tube and sensor cable; flexible cover tube bottom end and radio source position bolt socket are connected with three sensors along 120 degree direction on bolt socket; radio source position socket head and stabilizer are relative to the down supportive central hole; glue racket is fixed on the wave tube outsides stabilizer with radio glue dark case distributed on the glue racket.

Description

technical field [0001] The invention belongs to a positioning device, in particular to a welding seam radiographic inspection positioning device. Background technique [0002] The nuclear power plant voltage stabilizer is a barrel-shaped container with a height of more than 10 meters. The upper and lower parts are welded with a hemispherical head, and the diameter of the simplified body is about 3 meters. The voltage stabilizer is used to adjust the pressure of the primary circuit system of the nuclear power plant and is an important equipment of the nuclear power plant. The fluctuating pipe is connected to the lower head of the voltage stabilizer, and the connecting weld is located in the support group seat of the voltage stabilizer. [0003] According to the requirements of the relevant inspection specifications, radiographic inspection must be carried out on the welding seam of the nozzle, and a special positioning device must be used to complete the radiographic inspect...
