Embodiment Construction

[0038] The specific implementation of the device for measuring the wear of the outlet nozzle of the reactor internals and the method for measuring the wear of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] See attached figure 1 , 2 , the outlet nozzle 4 of the reactor internals is installed in cooperation with the pressure vessel cylinder, the end face of the outlet nozzle 4 is a cylindrical surface, and the frame 5 is fixed on the outside of the reactor internals cylinder 3, and the fixing method is to bind the frame with flexible straps 6 Wind around to the top of cylinder 3. Adjustment pads 2 are arranged around the frame 5 , and the adjustment pads 2 lock the frame 5 on the outlet nozzle 4 .

[0040] See attached image 3 , the adjustment pad 2 includes an upper block 9 and a lower block 10, the lower block 10 is fixed with the frame 5, the upper block 9 and the lower block 10 are matched by a slope, the u...

Abstract

The invention relates to the technical field of nuclear reactor equipment producing and machining, and discloses a reactor internal outlet pipe nozzle grinding and measuring device and a measuring and grinding method. An outlet pipe nozzle is and a pressure container cylinder are mounted in a matched manner, a cylindrical face is arranged on the end face of the outlet pipe nozzle, the measuring device comprises a frame, the frame is fixed to the outer side of a reactor internal cylinder, an adjusting pad is arranged on the periphery of the frame, the frame is locked on the outlet pipe nozzle through the adjusting pad, linear guide rails are arranged on the left side and the right side of the frame, and are located on the outer side of the outlet pipe nozzle, the linear guide rails are parallel to the axis of the reactor internal cylinder, a positioning ruler is arranged on the guide rails in a sliding manner, positioning holes are formed in the positioning ruler, and a depth gauge is used for measuring the depth of the outlet pipe nozzle through the positioning holes so as to determine the grinding amount. The measuring basis is determined through the depth gauge, point grinding amount measuring of the cylindrical face is achieved, the measuring process is simple, and the measuring and grinding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of nuclear reactor equipment, in particular to a grinding and measuring device for outlet nozzles of reactor internals and a method for measuring and grinding. Background technique [0002] When the nuclear power plant is installed on site, the gap between the end face of the outlet nozzle on the reactor internals and the pressure vessel is controlled by grinding. This end face is cylindrical and the amount of sanding cannot be determined when grinding this face with a hand tool. The direction of the grinding depth lacks a reference benchmark and cannot be measured with a standard ruler. [0003] If a laser tracking measuring instrument is used, the depth variation of each point on a longitudinal surface can be measured after the position is fixed, and a light target needs to be installed at each point of the measuring surface; the laser tracking measuring instrument also change...
