Abstract

The invention particularly relates to a steam generator primary side high-water-level closure plate sealing assembly. The sealing assembly comprises a sealing assembly body, a reinforcing rib, a first sealing line and a second sealing line, wherein the reinforcing rib, the first sealing line and the second sealing line are sequentially arranged on the inner wall surface of the sealing assembly body from inside to outside in the circumferential direction at intervals; and a super-elastic memory alloy ring is embedded in the reinforcing rib. The steam generator primary side high-water-level closure plate sealing assembly has the characteristic of variable stiffness and meets the requirements for folding and unfolding in the plugging work of a steam generator primary side main pipe opening.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment on the primary side of a steam generator, in particular to a high water level blocking plate sealing assembly on the primary side of a steam generator. Background technique [0002] Steam generator primary side high water level blocking plate, also known as steam generator high water level blocking plate device or steam generator primary side main pipe sealing blocking plate, is a special maintenance tool necessary for the maintenance of steam generator primary side water chamber . The high water level blocking plate on the primary side of the steam generator is installed on the flange ring seat of the main pipe port on the primary side of the steam generator, and is mainly used to seal the main pipe port on the primary side of the steam generator before the high water level reaches, so as to ensure that the water pool in the reactor is filled with water And steam generator water ch...
