Abstract

The invention belongs to the technical field of nuclear power station condensers, particularly relates to a vacuumizing device for the steam side of a nuclear power station condenser, and solves the welding problem of a vacuumizing pipeline and a titanium composite layer on the surface of a pipe plate by developing the vacuumizing pipeline of a stainless steel-titanium composite structure. The titanium composite layer is selected, the problem of corrosion of the vacuumizing pipeline in seawater is solved, the problem of corrosion of a welding seam between the vacuumizing pipeline and the titanium composite layer of the pipe plate is also solved, welding connection of the vacuumizing pipeline and the pipe plate is achieved, and the problem of sealing between the vacuumizing pipeline and the pipe plate is thoroughly solved. The hidden danger that seawater leaks to the condensed water side through a sealing structure between the vacuumizing pipeline and the pipe plate is eradicated, and the operation reliability of the condenser is improved.

Description

technical field [0001] The application belongs to the technical field of nuclear power plant condensers, and in particular relates to a vacuum device for the steam side of the nuclear power plant condenser. Background technique [0002] The condenser is the key equipment of the secondary circuit of the nuclear power plant. The function of the vacuum pumping pipe on the steam side of the condenser is to connect the vacuum pump to the steam side of the condenser, through which the non-condensable gas on the steam side of the condenser is drawn out, and together with the circulating cooling water system, the vacuum on the steam side of the condenser is maintained to ensure that the steam turbine The group is functioning normally. [0003] The vacuum pipe on the steam side of the condenser is generally arranged in the seawater chamber of the condenser, and is connected to the steam side of the condenser through the opening of the tube plate. The commonly used connection method...
