Abstract
The invention discloses a submarine pipe joint which can reduce impact of a sea current on flexible pipes. The submarine pipe joint comprises two butting joints, wherein one joint is a rigid joint, and the other one is a flexible joint. The front end of the rigid joint is a sectioned hollow sphere, and the rear end of the rigid joint is tubular. At least two rollers are arranged on the side edge of the front end of the flexible joint, the flexible joint is located in the rigid joint, the rollers and the inner wall of the rigid joint are in sliding fit, and the rear part of the flexible joint is tubular. An elastic pipe is arranged between the end face of the front end of the flexible joint and a pipe mouth in the rigid joint, and both ends of the elastic pipe are respectively in contact with the end face of the front end of the flexible joint and the pipe mouth in the rigid joint. When the pipes are subject to outside force of the sea current, the flexible joint adaptively rotates or swings in the rigid joint, and the impact force of the sea current on the flexible pipe is reduced.
Description
Technical field
The present invention relates to a kind of pipe coupling.
Background technique
Along with the continuous development and the raising of exploitation technology, recover the oil in China deep-sea and the gas production operation gets more and more, and this just need arrive the destination by line transportation with the oily gentle of extraction.At present preferred mode of movement mainly adopts the seabed to use flexible pipe to carry, and on the sea or shallow sea adopts rigid conduit to carry.This mode has characteristics such as cost is low, the life-span is long, but the conveyance conduit that is made of these two kinds of tubing exists the rigidity of tubing to differ bigger, rigid pipe and flexible pipe joint place can cause greater impact under the seabed ocean current impacts, this joint adopts traditional structure, can not absorb the impact energy of ocean current, flexible pipe is easily produced than large deformation in the joint, when serious flexible pipe is sustained damage and leakage of oil or gas leak phenomenon occur.
Summary of the invention
The purpose of this invention is to provide a kind of submarine pipeline joint that can reduce ocean current to the flexible pipe impact.
Technological scheme of the present invention is: comprise two butt joints, one of them is rigid joint, and another is flexible joint; Described rigid joint front end is the hollow ball that dissects, and the rear end is a tubulose; Described flexible joint front end arris is provided with at least two balls, and flexible joint is positioned at rigid joint, and ball and rigid joint inwall are slidingly matched, and the flexible joint rear portion is a tubulose; Be provided with spring tube between the mouth of pipe in the end face of flexible joint front end and the rigid joint, the spring tube two ends respectively with the end face of flexible joint front end and the mouth of pipe Elastic Contact in the rigid joint.
Flexible joint is positioned at rigid joint among the present invention, and flexible joint front end arris is provided with at least two balls, and ball and rigid joint inwall are slidingly matched.Do the time spent when being subjected to ocean current external force, flexible joint is rotated in rigid joint or is swung, and absorbs the impact energy of ocean current, reduces the impact force of ocean current to flexible pipe.Be provided with spring tube between the mouth of pipe in the end face of flexible joint front end and the rigid joint, the spring tube two ends respectively with the end face of flexible joint front end and the mouth of pipe Elastic Contact in the rigid joint, guaranteed that flexible joint well contacts with rigid joint all the time in rotation process, prevent that oil or the gas carried from spilling, impact energy that also can the absorption portion ocean current.
Description of drawings
Fig. 1 is the schematic perspective view of embodiment of the invention structure;
Fig. 2 is the cut-away illustration of Fig. 1;
Fig. 3 is the STRUCTURE DECOMPOSITION figure of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail, but does not constitute any limitation of the invention.Fig. 1, Fig. 2 and shown in Figure 3 the present invention includes two butt joints, and one of them is rigid joint 1, is used for being connected with rigid pipe.Another is flexible joint 2, is used for being connected with flexible pipe.Described rigid joint 1 front end is the hollow ball that dissects, and the rear end is a tubulose.Described flexible joint 2 front end arris are provided with at least two balls 4, and flexible joint 2 is positioned at rigid joint 1, and ball 4 is slidingly matched with rigid joint 1 inwall, and flexible joint 2 rear portions are tubulose.Be provided with spring tube 3 between the mouth of pipe in the end face of flexible joint 2 front ends and the rigid joint 1, spring tube 3 two ends respectively with the end face of flexible joint 2 front ends and rigid joint 1 in mouth of pipe Elastic Contact, in flexible joint 2 rotation processes, these two ends, spring tube 3 road keep tight resilient engagement with the end face of flexible head front end and the mouth of pipe in the rigid joint 1 respectively all the time, prevent leakage of oil or gas.When ocean current impacted, adaptability rotation or swing were done in flexible joint 2, absorb impact energy, reduce the excess impact of ocean current to flexible pipe.
