Problems solved by technology

[0002] In the past, due to the leakage of heavy water from the 30-inch fixture of the fuel exchanger, in the sealing surface of the magazine groove, magazine cover, and magazine end cover, when using a general measuring instrument, the seal formed in the shape of a metal ring and the sealing surface Inclination angle, it is difficult to measure the size before and after processing, and even if it can be measured, there will be a large measurement error due to structural problems, and it will also lead to low maintenance reliability

Abstract

The invention provides a measuring tool for the inner and outer diameters of the sealing surface of a fuel exchanger, which relates to a tool for measuring the inner and outer diameters of the sealing surface of a fuel exchanger in a heavy water furnace type atomic furnace power plant. According to the measuring tool, one side of a flat strip-shaped main body is equipped with a fixed support part for fixing a support roller assembly. A scale gauge is arranged opposite to the fixed support part and a variable support roller assembly is arranged opposite to the variable support part. Meanwhile, the central part of the fixed support part is equipped with a through hole for a shaft to pass through. An inner diameter measuring hole and an outer diameter measuring hole are respectively arranged close to and apart form the above the through hole. The fixed support part is arranged on one side of the inner diameter setting part and the outer diameter setting part of the main body. The variable support part is arranged on one side of the inner diameter setting part and the outer diameter setting part of the main body.

Description

technical field [0001] The invention relates to a tool for measuring the inner diameter and outer diameter of a sealing surface in a fuel exchanger of a heavy water furnace type atomic furnace power station. Background technique [0002] In the past, due to the leakage of heavy water from the 30-inch fixture of the fuel exchanger, in the sealing surface of the magazine groove, magazine cover, and magazine end cover, when using a general measuring instrument, the seal formed in the shape of a metal ring and the sealing surface It is difficult to measure the size of the inclination angle before and after processing, and even if it can be measured, there will be a large measurement error due to structural problems, and it will also lead to low maintenance reliability. Contents of the invention [0003] The present invention has been made in view of the above problems, and has the following objects. [0004] The purpose of this invention is to produce pitting corrosion due to...
