Abstract

The invention relates to the technical field of sealing ring sealing performance testing, in particular to a sealing ring dislocation sealing performance testing device and method. A sealing performance test device for dislocation of a sealing ring comprises a first flange and a second flange which are oppositely arranged, a placing space for a to-be-tested sealing ring is arranged between the first flange and the second flange, and the first flange or the second flange is provided with a detection hole; the pressurizing structure is connected with the first flange or the second flange; the force applying structure is arranged on the side face of the first flange or the second flange and used for applying acting force to the first flange or the second flange so that the first flange and the second flange can be dislocated; and the detector is connected with the detection hole. The invention solves the problem that the service life cannot be accurately evaluated due to the lack of a sealing performance detection device for O-shaped sealing ring dislocation, and provides the sealing performance test device and method for sealing ring dislocation.

Description

technical field [0001] The invention relates to the technical field of sealing ring sealing performance testing, in particular to a sealing ring displacement testing device and method. Background technique [0002] During the temperature and pressure load change process of the main flange of the steam generator shell of the high temperature gas-cooled reactor, the metal O-ring seal ring installed between the flange sealing surfaces will be misaligned, and the misalignment phenomenon is repeated during the start-up and shutdown process Appears, which has an adverse effect on the sealing performance of the metal O-ring. At present, the seal detection device cannot detect the sealing performance of the O-ring seal displacement, and cannot accurately evaluate the service life of the O-ring seal. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art of lacking a leak detection devic...
