Turnover device of steam-water separation reheater pipe system and application method of turnover device

Abstract

The invention discloses a turnover device of a steam-water separation reheater pipe system and an application method of the turnover device. The turnover device comprises a pipe plate support and a plurality of pipeline supports, the pipe plate support comprises a lower pipe plate support and an upper pipe plate support, and the pipeline supports comprise a lower pipeline support and an upper pipeline support; the connecting piece comprises a lower connecting piece and an upper connecting piece, the lower connecting piece connects the lower pipe plate support and the lower pipeline supports toform a lower frame, and the upper connecting piece connects the upper pipe plate support and the upper pipeline supports to form an upper frame; wherein the lower frame and the upper frame are buckled together, the steam-water separation reheater pipe system is limited between the lower frame and the upper frame, the lower pipe plate support and the upper pipe plate support are assembled and connected to form a circular first rotary supporting part, and the lower pipeline support and the upper pipeline support are assembled and connected to form a circular second rotary supporting part. Requirements of different products can be met, and overturning of different types of piping systems in the third-generation nuclear power steam-water separation reheater is achieved through overturning ofone piping system.

Description

technical field [0001] The invention is used in the field of steam-water separation reheaters, and in particular relates to a turning device for a steam-water separation reheater piping system and an application method thereof. Background technique [0002] During the welding process of the nuclear power steam-water separation reheater piping system and the gas chamber head, the piping system needs to be turned over to meet the requirements of the welding process. In the second-generation semi-nuclear power products, the size of the piping system is more than 10 meters, and the weight of the steam chamber is 3 tons; in the third-generation nuclear power products, the size of the piping system is extended to more than 20 meters, and the weight can reach nearly 70 tons. The weight of the steam chamber is 10 tons, which not only increases the size of the tube sheet and the head of the gas chamber, but also makes a great change in the structure of the piping system; since there ...

AI Technical Summary

Problems solved by technology

In the second-generation semi-nuclear power products, the size of the piping system is more than 10 meters, and the weight of the steam chamber is 3 tons; in the third-generation nuclear power products, the size of the piping system is extended to more than 20 meters, and the weight can reach nearly 70 tons. The weight of the steam chamber is 10 tons, which not only increases the size of the tube sheet and the head of the gas chamber, but also makes a great change in the structure of the piping system; since there are many types of third-generation nuclear power piping systems (such as ACP1000, AP1000 and ACP1400), the single-function piping turning device can no longer adapt to its changes

[0003] If a turning device is made according to a project of steam-water separation reheater, it is necessary to make turning devices with various structures, which not only wastes money, but also occupies a large amount of production space
