Technical field
The present invention relates to the vertical clamping hoop type connector of subsea manifold, belongs to even field of machines.
Background technology
The exploitation in deep water hydrocarbon field at present is investment height, the energy industry frontier that risk is big and new and high technology is intensive. Deep water underwater connector is mainly used in the connection between underwater production facility pipeline, such as subsea production tree and subsea manifold, underwater Pipeline and subsea production tree, PLET and PLEM etc., it is the important guarantee of deep water hydrocarbon safety in production.Application at present is deep at home and abroad Underwater connector form in the Development Engineering of aqueous hydrocarbon field mainly has two kinds of sleeve-type connector and clamping hoop type connector.Connect under water Connect device design, manufacturing technology to be monopolized by foreign oil equipment company all the year round, being badly in need of being formed now has the production of China's independent intellectual The deep water underwater connector designing technique of power, provide technology for China's deepwater oil-gas development and supported with equipment.
At present, subsea manifold connector construction mainly has two kinds:
(1) it is a kind of to be used for clamping hoop type connector connected horizontally.Clip is pipe fitting, valve and the pipeline for connecting with groove A kind of attachment means of accessory, used in playing contining function between fast joint.Using the bolt and nut fastening clamp on clip with Pipeline etc..But when pipeline inner flow passage medium, due to the impact of medium, the effect of thermal stress or the effect of other extraneous load, It is mutually shifted between clip and pipeline, thus reduces sealing effectiveness, leakage is occurred and even hinder whole manifold system to produce.
(2) it is a kind of to be used for sleeve-type connector connected vertically.Sleeve coupler is the pipe that with groove is caught by claw A kind of attachment means of part, valve and pipe line parts, used in serving promptly between fast joint.Although the connector structure Compact, sealing effectiveness is good, but its driving force derives from the hydraulic-driven of power tool, its huge structure and complexity, especially It is to take oversize when maintenance, improves worker's labor intensity, add the off-time, reduce oil well output.
The content of the invention
Goal of the invention:In order to overcome the deficiencies in the prior art, the present invention proposes a kind of vertical clip of subsea manifold Formula connector, a bulb tube joint component is used, avoided under water in manifold connection procedure because the stress of manifold is curved Qu Xuanzhuan and cause whole connector to collapse, substantially increase the operability of ROV robots.
Technical scheme:In order to solve the above technical problems, the vertical clamping hoop type connector of subsea manifold of the present invention, including down tube And bulb tube, the top of the down tube are provided with connection boss, the lower surface for connecting boss is inverted cone mesa-shaped, and down tube passes through sealing Circle is connected with connection ring, and connection ring is connected with bulb tube, and hoisting ring is cased with outside bulb tube, support, support are cased with outside hoisting ring Lower end wraps connection boss, and hoisting ring and support are fixed by clip;The middle and upper part of the down tube is provided with circle convex platform, in circle The circular support block of support circle convex platform is provided with below ring convex platform, the face of cylinder of circle convex platform passes through spring washer and fixed cover Connection, fixed cover include the simplified of cylinder, and simplified top is provided with circular hole, and circular hole is connected with spring washer, simplified lower end Be extended with annulus installing plate, several fixed blocks be installed on annulus installing plate, fixed block simultaneously with simplified connection, fixed block Provided with inclined-plane, guide sleeve is located on the inclined-plane of fixed block, and locating ring is provided with guide sleeve.
Preferably, the bottom of the connection ring has upwardly extended convex platform and has extended downwardly lower convex platform, convex platform with Connection ring forms groove, and hoisting ring and bulb tube one end are inserted into groove.
Preferably, the support includes left socle unit and right support unit, the left socle unit and right support list For member comprising the semicolumn body that section is semicircle, it is convex that the top and bottom of semicolumn inner body wall are respectively extended with upper limit Platform and lower limit boss, upper limit boss are pressed on convex platform, and lower limit boss wraps connection boss, in semicolumn body Both sides are extended with latch, and bolt is provided with latch, by bolt and latch by left socle unit and right support list Member locking.
Preferably, being provided with trip bolt on the lower convex platform, trip bolt is connected with positioning mandril, positioning mandril one End is inserted into sealing ring, by turn trip bolt, drives positioning mandril to be inserted into sealing ring, lock sealing circle.
Beneficial effect:The vertical clamping hoop type connector of subsea manifold of the present invention, has advantages below:
(1) clamp coupling is disposed vertically, and is avoided due to the impact of medium, the effect of thermal stress or other extraneous loads The effect of lotus, it is mutually shifted between clip and pipeline and causes to reduce sealing effectiveness.
(2) bulb tube part interconnects convenient when the part assembles and safety by a series of parts Reliably, it is and simple in construction.Particularly when maintenance, greatly reduce time-consuming, reduce worker's labor intensity, when reducing stopping production Between, improve oil well output.
(3) bulb tube part has used a bulb tube joint component, is avoided under water in manifold connection procedure Cause whole connector to collapse due to the stress Bending Rotation of manifold, substantially increase the operability of ROV robots.
