Abstract
The utility model provides a kind of capsule-type oil pipe fracture plugging device, for quick, the reliable shutoff of fracture in oil and gas pipes demolishing process.Primarily of compositions such as ring seal capsule, capsule pull bar, capsule fixed base plate, capsule movable pressure plate, fixed support, lock screw, capsule tracheae, valve, rapid pipe joints, realize seal for pipe joints by the inflation of ring seal capsule, realize capsule-type oil pipe fracture plugging device fixing in pipe end position by the lock screw on fixed support.It has the features such as shutoff is reliable, easy and simple to handle rapidly, strong adaptability, reusable edible.
Description
Technical field
The utility model relates to a kind of capsule-type oil pipe fracture plugging device and oil transport pipeline fracture rapid plugging method, belongs to petroleum pipeline constructing device field.
Technical background
Be one of important process of Oil Safety exploitation to dismounting that is damaged and extended active duty petroleum pipeline, the petroleum pipeline must removed every year according to incompletely statistics reaches dozens of kilometres.For ease of Demolition Construction, the technique adopted at present is duct segments cutting disassembling, and the length of every section is at about 10m ~ 20m.Due in segmentation demolishing process, accumulate residual oil mixing with water liquid in pipeline easily flow out and cause secondary pollution to environment, in demolishing process, shutoff must be carried out to oil pipe fracture site, require the features such as shutoff is reliable, manufacturing process is simple, convenient and rapid, strong adaptability, reusable edible.Method for blocking conventional at present has the shutoff of section flange and pipe inner seal ring shutoff two kinds of modes.Wherein, section flange method for blocking adopts at pipe end position mounting flange and sealing gasket, shutoff is realized by the extruding of sealing gasket on flange and pipe end face, there is the advantage that plugging strength is high, but operating procedure is complicated, shutoff efficiency is lower, higher to the flatness requirement of pipeline fracture, and field conduct is comparatively difficult.Pipe inner seal ring mode realizes sealing with inner-walls of duct by the multiple-sealed circle on blocked shot, and have advantage easy and simple to handle, but plugging strength is low, simultaneously the easy landing when distortion appears in pipeline or inwall oil film is thicker, the reliability of shutoff is poor.
Model utility content
The purpose of this utility model is for solving the problem, and provides a kind of capsule-type oil pipe fracture plugging device, for quick, the reliable shutoff of fracture in oil and gas pipes demolishing process, and improves applicability and the reusable edible of plugging device.
The capsule-type oil pipe fracture plugging device that the utility model relates to comprises ring seal capsule, capsule pull bar, capsule fixed base plate, capsule movable pressure plate, fixed support and capsule tracheae; Wherein, capsule pull bar is connected with fixed support through one end after the core bore of ring seal capsule (1), capsule fixed base plate and capsule movable pressure plate split in the both sides of ring seal capsule, capsule fixed base plate and capsule pull bar are connected, capsule movable pressure plate and capsule pull bar are threaded connection, and capsule tracheae is communicated with ring seal capsule.
Above-mentioned capsule-type oil pipe fracture plugging device also comprises: fixed support outer periphery is provided with annular sleeve, annular sleeve is radially distributed with several lock screws.
The capsule tracheae of ring seal capsule connects valve and rapid pipe joint.
Capsule-type oil pipe fracture plugging device of the present utility model has reasonable in design, and plugging effect is good, can reuse; Coordinate the method for this device can realize quick, the reliable shutoff of fracture in offshore oil and gas pipeline demolishing process, there is the advantages such as shutoff is reliable, easy and simple to handle rapidly, strong adaptability, reusable edible.
Accompanying drawing explanation
Fig. 1 is a kind of capsule-type oil pipe fracture plugging device structural representation.
In figure: 1-ring seal capsule, 2-capsule pull bar, 3-capsule fixed base plate, 4-capsule movable pressure plate, 5-fixed support, 6-lock screw, 7-capsule tracheae, 8-valve, 9-rapid pipe joint.
Embodiment
As shown in Figure 1, a kind of capsule-type oil pipe fracture plugging device of relating to of the utility model is primarily of compositions such as ring seal capsule 1, capsule pull bar 2, capsule fixed base plate 3, capsule movable pressure plate 4, fixed support 5, lock screw 6, capsule tracheae 7, valve 8, rapid pipe joints 9.Wherein, fixed support 5, capsule fixed base plate 3, capsule pull bar 2 are fixedly connected with, capsule movable pressure plate 4 is arranged on the end of capsule pull bar 2 by screw thread, ring seal capsule 1 is enclosed within capsule pull bar 2 by core bore, and be installed between capsule fixed base plate 3 and capsule movable pressure plate 4, according to shutoff demand, regulate the space between capsule fixed base plate 3 and capsule movable pressure plate 4.The annular sleeve size of fixed support 5 is greater than outer diameter tube, it is established several tapped through holes, for installing lock screw 6, realizes being connected and fixed between fixed support 5 and pipeline, increases plugging strength.That capsule tracheae 7 is established in ring seal capsule 1 one end, and mounted valve 8 and rapid pipe joint 9 successively, for the fast aeration of ring seal capsule, venting and pressurize.
By the concrete implementation step adopting above-mentioned capsule-type oil pipe fracture plugging device to carry out oil transport pipeline fracture rapid plugging method be:
(1) open capsule movable pressure plate 4, after loading ring seal capsule 1, capsule movable pressure plate 4 is installed, and is adjusted to appropriate location;
(2) fill in pipeline by the ring seal capsule 1 of capsule-type oil pipe fracture plugging device, rapid pipe joint 9 connects source of the gas, and inflates ring seal capsule 1, and after ring seal capsule 1 and inner-walls of duct seal, throttle down 8, prevents Leakage Gas.
(3) tighten lock screw 6, and lock screw 6 top and pipeline outer wall are clamped, realize the fixing of fixed support 5, ensure the plugging strength of capsule-type oil pipe fracture plugging device.
Claims (3)
1. a capsule-type oil pipe fracture plugging device, is characterized in that comprising ring seal capsule (1), capsule pull bar (2), capsule fixed base plate (3), capsule movable pressure plate (4), fixed support (5) and capsule tracheae (7); Wherein, capsule pull bar (2) is connected with fixed support (5) through one end after the core bore of ring seal capsule (1), capsule fixed base plate (3) and capsule movable pressure plate (4) split the both sides in ring seal capsule (1), capsule fixed base plate (3) and capsule pull bar (2) are connected, capsule movable pressure plate (4) and capsule pull bar (2) are threaded connection, and capsule tracheae (7) is communicated with ring seal capsule (1).
2. capsule-type oil pipe fracture plugging device according to claim 1, is characterized in that: fixed support (5) outer periphery is provided with annular sleeve, annular sleeve is radially distributed with several lock screws (6).
