Chinese invention patent "A Balanced Expansion Joint for Small Spaces", the application number is: The expansion joint described in CN103277625B uses three basic expansion joints and a properly set hinge structure to form a composite expansion joint. It realizes the function of absorbing axial and transverse directions at the same time; in the heat exchanger, the ordinary expansion joint can realize the displacement compensation in one direction between different equipments, but the displacement compensation in the two-dimensional direction requires a separate compensation unit for the two-dimensional direction , and the composite expansion joint in the prior art, because it requires a certain installation space, the installation in the heat exchanger is limited by the space, it is difficult to apply the above composite expansion joint to compensate the two-dimensional displacement

Abstract

The invention provides a two-dimensional expansion joint. The two-dimensional expansion joint comprises an expansion joint body; the vertical cross section of the expansion joint body comprises a longitudinal corrugation part, a connecting part and a transverse corrugation part which are connected in sequence; the longitudinal corrugation part comprises at least one longitudinal corrugation section, each longitudinal corrugation section comprises a longitudinal wave arc segment and longitudinal wave extended segments connected with the two ends of the longitudinal wave arc segment, and the central axis of each longitudinal wave arc segment is parallel to the transverse direction; the transverse corrugation part comprises at least one transverse corrugation section, each transverse corrugation section comprises a transverse wave arc segment and transverse wave extended segments connected with the two ends of the transverse wave arc segment, and the central axis of each transverse wave arc segment is parallel to the longitudinal direction. According to the two-dimensional expansion joint, on the basis of a corrugated expansion joint displacement compensation mechanism, the longitudinal wave arc segments of the longitudinal corrugation part of the expansion joint body has an absorption effect on longitudinal displacement, the transverse wave arc segments of the transverse corrugation part of the expansion joint body has an absorption effect on transverse displacement, the function of compensating displacement in the longitudinal direction and the transverse direction simultaneously can be achieved.

Description

technical field [0001] The invention relates to the field of expansion joints, in particular to a two-dimensional expansion joint. Background technique [0002] Expansion joints are compensation structures used in industrial equipment. For example, in heat exchangers, between the heat exchange core and the frame or between the frame and the frame, different deformations will occur due to thermal expansion or mechanical load between different components. It is necessary to set up a displacement compensation unit to compensate for the large stress at the connection position to prevent failure; the expansion joint can be applied to the displacement compensation position in the heat exchanger because of its simple structure, convenient installation, and good displacement compensation effect. [0003] The expansion joint has a good compensation effect on its axial deformation. If the axial and lateral displacements are compensated at the same time, it is necessary to use a compos...
