Problems solved by technology

[0003] The rubber gasket has an aging life, because it cannot be replaced, after a period of operation, the seal fails due to the aging of the rubber gasket, and seawater enters the threaded part between the tie bars and the tube sheet, causing corrosion to the tube sheet
Long-term corrosion will cause seawater to enter the condensed water side, causing the quality of condensed water to deteriorate. In severe cases, it may cause tripping or even tripping

Abstract

The invention belongs to the technical field of mechanical design, and particularly relates to a condenser seawater chamber tie bar structure. The tiepiece comprises a tiepiece base body, a tiepiece titanium composite layer, a tube plate titanium composite layer and a tube plate base body, the tiepiece titanium composite layer is arranged on the outer surface of the tiepiece base body, the tube plate titanium composite layer is arranged on the outer surface of the tube plate base body, and the tiepiece base body is connected with the tube plate base body through threads. Sealing is guaranteed under the condition that the connecting strength of the lacing wire and the tube plate is guaranteed, the problem of aging does not exist, the hidden danger that seawater leaks when passing through a sealing structure between the lacing wire and the tube plate is permanently eliminated, and the running reliability of the condenser is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to a seawater chamber tension structure of a condenser. Background technique [0002] The seawater chambers of the condensers of units 1 and 2 of a nuclear power plant have a rectangular structure. In order to ensure the structural rigidity of the seawater chambers, the seawater chambers are equipped with tension bars in the three-dimensional directions of length, width and height. The material of the tie bars is the same as that of the wall plate of the seawater chamber, and the tie bars and the wall plate of the seawater chamber are connected by welding. The material of the tube sheet is a titanium composite plate structure, which cannot be welded with the tie bars. It is generally designed as a threaded connection. The seawater side seal is realized by rubber gaskets, and the condensate side seal is realized by seal welding on the steam side. The tie bars c...
