Riser joint connection structure and riser module
ActiveCN121576480BTo achieve a fixed connectionDisconnect
This invention belongs to the field of marine engineering equipment technology, and relates to a riser connector connection structure and riser module. The riser connector connection structure includes a wedge block, a wedge groove, and an inlet groove. The wedge groove and the inlet groove are connected, and their connection has a stepped structure. When the wedge block is inserted axially into the inlet groove, the male and female connectors rotate relative to each other, allowing the wedge block to rotate into the corresponding wedge groove through the stepped structure. The wedge groove restricts the axial and radial movement of the wedge block, and the wedge groove, in conjunction with the stepped structure, restricts the circumferential movement of the wedge block. The technical solution provided by this riser connector connection structure and riser module, on the one hand, can improve the pressure resistance and reliability of the connection between two risers to a certain extent, while also achieving lightweighting of the riser connector connection structure; on the other hand, it simplifies the detachable operation method between the two pipe fittings and significantly reduces maintenance and upkeep costs.
