Description
Technical field
The utility model belongs to the sea oil drilling and production equipment technical field, relates to the automatic fixing device of a kind of metallic seal gasket ring.
Background technology
Under the sea oil drilling and production operating environment, manually be difficult to the operating mode of operating or can't operate for adapting to deep water, method that just must be by remote control operation is to satisfy the job requirements under the particular surroundings such as ocean.Metallic seal gasket ring in the ocean water lower connecting device has adopted the gasket ring fixing device, and fixing device is the key device in the metallic seal gasket ring automatic installation apparatus automatically.The metallic seal gasket ring is to be used for two end face interfaces that are connected device are sealed, because its sealing is reliable, resistance to corrosion is strong, environmental applications is more extensive under water, but gasket ring generally all is a consumable accessory, need running check even replacing, yet in the underwater environment of ocean, if finish very difficult with manually-operated mode the installation of metallic seal gasket ring, dismounting or even be difficult to realize, if and each installation, inspection, dismounting all finish across the sea, then can strengthen cost.
Summary of the invention
The purpose of this utility model provides the automatic fixing device of a kind of metallic seal gasket ring, has solved under the ocean deepwater environment existing gasket ring and has manually installed, dismantles difficulty especially, checks, changes very inconvenient problem.
The technical scheme that the utility model adopted is, the automatic fixing device of a kind of metallic seal gasket ring, in body, be provided with working chamber, be disposed with circlip, plug, sleeve, spring, push rod in this working chamber, circlip is installed on the interior hole slot of body, sleeve set is on the cylindrical of plug, spring, push rod, and the space between sleeve, the push rod constitutes a hydraulic cavities; Push rod passes body and metallic gasket loop contacts, hydraulic cavities and hydraulic control device UNICOM.
Automatic fixing device of the present utility model, its feature also is: be provided with a plurality of sealings separately between the inwall contact surface of described sleeve and working chamber and between the circumferential contact face of sleeve and push rod.
Described circlip adopts jump ring or split washer.
The cushion block of annular is housed on the described push rod end.
Described automatic fixing device is provided with a plurality of along the circumferencial direction of body.
Apparatus structure of the present utility model is simple, connection and reasonable arrangement, can effectively replace operating manually, can realize the long-range operation of the metallic seal gasket ring of equipment being carried out automatic locking and release, have the advantage of not damaging sealing surface, convenient to operation, good reliability, satisfied ocean underwater installation linking automation and high reliability request.
Description of drawings
Fig. 1 is an embodiment sectional view of the utility model device;
Fig. 2 is another embodiment sectional view of the utility model device;
Fig. 3 is the sectional drawing of Fig. 1 along the push rod center line.
Among the figure, 1. circlip, 2. plug, 3. sleeve, 4. spring, 5. push rod, 6. sealing, 7. body, 8. metallic seal gasket ring, 9. hydraulic control device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As Fig. 1, hydraulic controlling type gasket ring fixing device along continuous straight runs of the present utility model is provided with, its structure is, in body 7, be provided with working chamber, be disposed with circlip 1 in this working chamber, plug 2, sleeve 3, spring 4, push rod 5, circlip 1 is installed on the body 7 interior hole slots, restriction plug 2 outwards moves, sleeve 3 is sleeved on plug 2, spring 4, on the cylindrical of push rod 5, sleeve 3, space between the push rod 5 constitutes a hydraulic cavities, is provided with a plurality of sealings 6 between the inwall contact surface of sleeve 3 and working chamber and between the circumferential contact face of sleeve 3 and push rod 5 separately; Push rod 5 passes body 7 and contacts with metallic seal gasket ring 8, and hydraulic cavities and hydraulic control device 9 connect with thread forms between plug 2 and the sleeve 3 by pipeline UNICOM.
As Fig. 2, the angled setting of the utility model device and horizon, it is consistent with Fig. 1 embodiment that internal construction is provided with, and the common axis line and the horizon that are circlip 1, plug 2, sleeve 3, spring 4, push rod 5 are angled, and push rod 5 is the oblique angle with metallic seal gasket ring 8 and contacts.
As Fig. 3, can along the circumferential direction arrange a plurality of gasket ring fixing devices unit, reach the more fixedly purpose of gasket ring, realize metallic seal gasket ring 8 is locked control more flexibly.A plurality of gasket ring fixing devices along the circumferential direction are arranged in metallic seal gasket ring 8 and are in the same horizontal plane, as Fig. 1, also can be arranged in the angled position of the horizontal plane at metallic seal gasket ring 8 places on, as Fig. 2.
Adopt circlip 1 or take forms such as jump ring, split washer to limit the motion of plugs 2.
The cushion block of an annular can be housed on the push rod end, and the contact area of increasing and metallic seal gasket ring makes push rod 5 hold out against the purpose that metal gasket ring 8 reaches maintenance.Two sealing surfaces up and down of metallic seal gasket ring 8 have been avoided at the groove of metallic seal gasket ring 8 end faces in the position that push rod 5 and metallic seal gasket ring 8 hold out against, so just reached neither injure sealing surface again can be to its fine fixing purpose.After the gasket ring fixing device is realized quick release to gasket ring, underwater robot will go to carry out next step operation again with metallic seal gasket ring 8, when need more renew gasket ring, underwater robot will be fetched new gasket ring, and metallic seal gasket ring 8 is put in place by instrument, then next plays action to this gasket ring fixing device in the effect of spring restoring force again, realizes the locking to metallic seal gasket ring 8.
The operating principle of the utility model device is: this metal gasket ring fixing device adopts hydraulic pressure and the box-like control of groups of springs, under the normal condition, spring 4 between sleeve 3 and push rod 5 is in compressive state, under the effect of spring restoring force, drive radially inwardly motion of push rod 5, metallic seal gasket ring 8 is held out against, to realize locking operation to metallic seal gasket ring 8, when needs are changed or are checked metallic seal gasket ring 8, just must realize automatic unlocking by Long-distance Control, promptly when the oil circuit to this device hydraulic cavities feeds hydraulic oil, all push rods of along the circumferential direction arranging will overcome radially outwards motion of spring force under the effect of hydraulic oil, keep motionless and plug is basic under the effect of circlip and external water pressure, so just can realize release to metallic seal gasket ring 8 fast.
The utility model device can effectively replace operating manually, can realize long-range the metallic seal gasket ring of equipment being carried out the operation of automatic locking and release, has the advantage of not damaging sealing surface, convenient to operation, good reliability.This device is mainly used in the ocean water lower connecting device, to satisfy ocean underwater installation linking automation requirement and high reliability request.
