Abstract
The utility model provides a threaded-type riser joint which is composed of a male joint and a female joint, wherein the male joint is matched with the female joint, flat-top taper threads and locking pieces provided with locking teeth are arranged on the periphery of the male joint, and flat-top taper threads and embedded pieces provided with locking teeth are arranged on the periphery of the female joint. The flat-top taper threads of the male joint correspond to the flat-top taper threads of the female joint, and the locking pieces of the male joint correspond to the embedded pieces of the female joint. The threaded-type riser joint has the advantages that on-site connection speed is quick, the joint can be screwed by rotating three fourths circle, in addition, the structure is firm, and the locking structure guarantees that the threaded-type riser joint can be used in serious use environment.
Description
Technical field
The utility model relates to a kind of oil field fastening means, particularly relates to a kind of riser joints.
Background technology
Along with the progressively expansion of country to energy demand, the fast development of offshore oil industry, the marine petroleum development technology is showing improvement or progress day by day, in order to satisfy more adverse circumstances Ocean oil exploitation needs, usually need marine riser as the outermost layer pillar, at present the joint that adopts of marine riser mostly is circlip type, and the tensile strength of circlip type riser joints is not enough, can't satisfy darker, the demand of adverse circumstances Ocean oil exploitation more.
The utility model content
In order to solve problems of the prior art, the utility model provides a kind of screw-type riser joints, solves marine petroleum exploitation riser joints tensile strength deficiency in the prior art, can't satisfy the problem of marine petroleum exploitation demand.
The technical scheme that the utility model adopts has: be comprised of male joint and female joint two parts, male joint matches with female joint, the male joint periphery is provided with the lock dog of flat-top taper thread and locking tooth, and the female joint periphery is provided with inserting of flat-top taper thread and locking tooth; The flat-top taper thread of male joint is corresponding with the flat-top taper thread of female joint; The lock dog of male joint is corresponding with inserting of female joint.
Male joint and female joint flat-top taper thread are 6 line screw threads, tapering 1:6.
The male joint periphery is provided with the lock dog of 6 locking teeth.
The female joint periphery is provided with inserting of 6 locking teeth.
Respectively there is a spring leaf at each lock dog place.
Pin and box sub is twisted in the termination process, lock dog with insert from movingly.
Female joint is provided with seal groove, and O-ring seals is housed.
Compared with prior art, the utility model has the advantages that: 1, connection speed is faster, more convenient, only needs stubborn 3/4 circle that connects; 2, structure is more firm, twists in the termination process lock dog and inserts from movingly; 3, after the connection, safety and reliability in the use procedure.
The utility model is developed a kind of screw-type riser joints on existing Offshore Drilling Riser joint basis, is mainly used in the marine drilling engineering.Not only connection speed is fast for this kind screw-type riser joints, only needs 3/4 circle to tighten, and intensity is high simultaneously, possesses automatic fastening function, uses more safe and reliable, satisfied more adverse circumstances Ocean oil exploitation operation.

The specific embodiment
This screw-type riser joints syndeton, formed by male joint 1 and female joint 6 two parts, male joint matches with female joint, the male joint periphery is provided with the lock dog 3 of male joint flat-top taper thread 4 and 6 locking teeth, and what the female joint periphery was provided with female joint flat-top taper thread 9 and 6 locking teeth inserts 8; Male joint flat-top taper thread 4 is corresponding with female joint flat-top taper thread 4, and is 6 line screw threads, tapering 1:6; Inserting of the lock dog 3 of male joint and female joint is 8 corresponding.Respectively there is a spring leaf 7 at each lock dog 3 place.Pin and box sub is twisted in the termination process, lock dog 3 with insert 8 from movingly.Female joint 6 is provided with seal groove, and O-ring seals 5 is housed.Six boat nails 2 were fixing in lock dog 3 in the male joint 1 passed through 1; Inserting in the female joint 6 is 8 fixing by six boat nails 2 in two.
During connection, female joint 6 is inserted in male joint 1, to right rotation 3/4 circle, the flat-top taper thread of pin and box sub screws automatically immediately; Lock dog 3 with insert 8 from movingly.
The design of this screw-type riser joints, but take into full account low cost, the high efficiency characteristics of marine petroleum exploitation, meet the more service condition under the adverse circumstances such as ocean wind regime, morning and evening tides, surge.Satisfy instructions for use, connection speed is fast, and intensity is high.
