Embodiment Construction
[0013] A clamp type marine underwater pipeline connector, such as figure 1 , figure 2 , image 3 As shown, it includes the left and right flanges 8, 9 welded on the ends of the connected pipes and the flange locking mechanism, and the opposite end faces of the left and right flanges 8, 9 are coaxially provided with secondary seals from the outside to the inside. The ring 11 and the annular grooves and ribs that are interference-sealed with each other. The three outer peripheral surfaces of the annular ribs are all conical surfaces, and the three contact surfaces of the corresponding annular grooves are also conical surfaces. Said annular grooves and ribs can be arranged in multiple shapes such as partial trapezoid, trapezoid, rectangle, etc. as required. The auxiliary sealing ring 11 is set as two, three or other multiple seals as required.
[0014] The inner walls of the end pipes of the left and right flanges are all conical surfaces, and an annular concave step is arran...

The invention discloses a clamping type ocean underwater pipeline connector which comprises a left flange, a right flange and a flange locking mechanism. An auxiliary seal ring, ring-shaped grooves and a ring-shaped protruded edge are respectively arranged on the opposite end faces of the left flange and the right flange in a coaxial mode from outside to inside, wherein the ring-shaped grooves and the ring-shaped threads are in mutual interference fit in a sealing mode. The inner walls of end pipes of the left flange and the right flange are cone-shaped surfaces, ring-shaped concave steps are arranged on the outer edges of the cone-shaped surfaces, backing rings are arranged in the cone-shaped surface end pipes in an interference sealing fit mode, and the outer periphery walls of the backing rings respectively make contact with the ring-shaped concave steps and the cone-shaped surfaces. An upper locking arm and a lower locking arm are hinged to the upper end and the lower end of a locking base of the locking mechanism respectively. The locking arms are respectively composed of two pressing plates. Two connecting hinge pins are horizontally arranged between the free ends of the two pressing plates of the upper locking arm and between the two pressing plates of the lower locking arms respectively, wherein the connecting hinge pins are provided with center threaded holes. A vertically arranged threaded operating rod penetrates through the threaded holes in the two connecting hinge pins, and the cone-shaped back edges of the left flange and the right flange are located between the two pressing plates of the upper locking arm and between the two pressing plates of the lower locking arm respectively.
Description
technical field [0001] The patent of the invention belongs to the technical field of offshore oil drilling, gathering and transportation equipment, and specifically relates to a clamp-type marine underwater pipeline connector, which can quickly connect to offshore drilling and gathering and transportation pipelines (manifolds), offshore drilling risers, oil production risers, Take over etc. Background technique [0002] The marine underwater pipeline coupling is a very important tool for underwater drilling, collection and transportation equipment. It is widely used between various underwater equipment, between underwater equipment and pipelines, and between pipelines. In the field of marine underwater pipeline coupling technology, it is still in its infancy in China. [0003] At present, there are three types of marine underwater pipeline connectors commonly used: flange type, clamp type and claw type. The flange type is mainly used in shallow seas and needs to be install...
