Description
Technical field
A kind of quick reparation when occurring leakage the present invention relates to ocean engineering field submarine pipeline or damage connects dress
Put, it is more particularly to a kind of quickly to repair attachment means in the presence of eccentric deviation adjustable type when changing submarine pipeline under water.
Background technology
Submarine pipeline is played an important role in the production of hydrocarbons of ocean engineering field, it by offshore platform and platform,
Offshore platform and land terminal and offshore platform and FPSO (Floating Production oil storage easing gear) etc. be connected into one it is organic whole
Body, is responsible for defeated outside the oil gas mediums such as Oil/gas Well Produced Liquid, qualified crude oil, associated gas, the weight such as chemical agent conveying and water filling
Want production task.There is the reality such as risk is big, failure probability is high due to the particularity of its seabed operating mode running environment in submarine pipeline
Situation, once leaking, not only causes marine environmental pollution, petroleum resources to waste and oil field production disruption, and can be to it
The normal production and life of downstream and terminal user are adversely affected.
For specific submarine pipeline damage type, pipe clamp leak stopping, composite reinforcement and pipeline section under water can be taken at present
Three kinds of Main Means are changed, pipe clamp leak stopping recovery technique the advantage is that using mechanical closure and be implemented simple, duty cycle
It is short, available for the pipe leakage caused by reason such as burn into mother metal defect, crackle, once but submarine pipeline occur serious damage or
There is moderate finite deformation, the technology is just difficult to effective closure and repaired.Composite reinforcement recovery technology, such as notes epoxy resin
Material, the recovery technique easily produces impact failure to the body of submarine pipeline, and injecting equipment is complicated huge in itself, live material
Make and underwater operation complex process, be unfavorable for the quick reparation of submarine pipeline.The technology of pipeline section Replacement and Repair under water is characterized in
It is applied widely, it the various forms of submarine pipelines breakages such as can complete to corrode or be broken and repair, but have the disadvantage the mechanical company of reparations
The production technology for connecing device this key spare parts is grasped in specialized company's hand abroad always, and the country does not form corresponding research and development also
With production technology ability, its external order cycle time dean.
The content of the invention
For the defect for effectively solving the problems, such as the quick reparation of submarine pipeline and overcoming existing recovery technique to exist with equipment
And deficiency, occur leakage it is an object of the invention to provide a kind of suitable submarine pipeline or change the quick of pipeline section under water when damaging
Repair attachment means.The quick reparation attachment means are organically combined using metal and a variety of Sealing Technologies such as nonmetallic, it is ensured that even
The fixation and sealing of connection device and pipeline enclosure, and special tectonic and the retaining mechanism of locator according to sphere deviation adjustable type, it is real
Eccentric adjusting and attachment means in existing repair between submarine pipeline are automatically positioned, possess simple to operate, repair time it is short,
The low feature of operation intensity.
The technical solution adopted for the present invention to solve the technical problems is that a kind of deviation adjustable type submarine pipeline of exploitation is quickly repaiied
Multiply-connected connection device, is made up of device for adjusting deviation, pushing body, primary seal device, locator and auxiliary seal box successively from top to down.Device for adjusting deviation with
The submarine pipeline newly changed is coupled, and primary seal device, locator and auxiliary seal box are fixed with the pipe end after cutting, repair
In multiple operation, this quickly repair attachment means first by the tuningout body of device for adjusting deviation and the submarine pipeline newly changed weld it is prefabricated
Together, then implement the lower water of lifting and carry out underwater mating with the submarine pipeline pipe end after cutting；Then device for adjusting deviation tuningout is passed through
The collective effect of mating spherical surfaces and each spherical washer between body and tuningout seat, completes the new bias for changing pipeline and cutting pipeline enclosure
Regulation, and quickly screw each tuningout bolt, the clamping pressure transmitted by tuningout body, upper zero type sealing ring and upper hexagon gold
Category ring is deformed and forms the sealing of zero type sealing ring and metal loop seals；Then the whole quick company of reparation is moved axially along pipeline
Lock pin in connection device, device retaining mechanism to be positioned, which is slipped into, completes attachment means in cutting after the ring-shaped groove of cutting pipe prefabrication
Positioning on pipeline；Then each clamping stud of locator, the thrust transmitted by locating bodies, trapezoidal quoit axle are screwed
It is deformed to movement and after progressively being fitted with cutting pipe prefabrication anchor ring, forms trapezoidal quoit sealing；Pushed away followed by screwing
Each propulsion stud entered on body, extrudes rectangular metal circle, cone-shaped metal circle and lower hexagonal metallic ring and is deformed successively, and
Form quoit sealing and metal loop seals；Each regulation stud of auxiliary seal box is finally screwed, packing is extruded by gland and produced
Change shape, and forms packing seal, final to realize the new connection for changing pipeline and cutting pipeline enclosure.
The quick reparation attachment means global design is heavy wall tubular revolving body construction, the material of its critical piece with newly
The material for changing pipeline and cutting pipeline is consistent, while it is close using two kinds of metal sealings of quoit and becket and zero type
Seal sealing and the nonmetallic sealedly a variety of Sealing Technologies of two kinds of packing seal are organically combined, and are reached optimal with learning from other's strong points to offset one's weaknesses
Sealing effectiveness.Wherein, quoit Sealing Technology include rectangular metal circle, cone-shaped metal circle and trapezoidal quoit, rectangular metal circle,
