Abstract
The invention relates to a bandage slips blocking device applicable to leakage of a pipeline. The bandage slips blocking device is provided with a blocking ball valve, a sealing slips, a sealing ring, connection screw rods and locking chains, wherein the blocking ball valve is connected with the sealing slips through a flange; the sealing slips is semicircular; the sealing ring is arranged on the inner side wall of the bottom face of the top end of the sealing slips; the connection screw rods are arranged at the opposite corners of the two ends of the sealing slips and used for being connected with the locking chains. Through compressional deformation of the sealing ring of the sealing slips, a closed cavity is formed between the blocking device and the leakage position of the pipeline, the locking chains fix the sealing slips, the construction period for blocking the pipeline with small deformation and a small leakage point can be effectively shortened under the condition of not stopping production, construction and operation are convenient and rapid, and the construction cost is low.
Description
Technical field
The present invention relates to a kind of blocking device, particularly about a kind of blocking device being applicable to submerged pipeline and leaking.
Background technique
Submerged pipeline is the lifeline that offshore oilfield is produced, and is a kind of shipping channels the most frequently used in Offshore Oil Industry.Its advantage is can continus convergence, and hardly by the restriction of the condition such as the depth of water, landform, and it is short to lay the duration, and go into operation fast, oil transportation efficiency is high, and ability is large, is a requisite part in offshore oil production system.But its shortcoming is pipeline is in seabed, majority is again be embedded in certain depth in seafloor soil, once pipeline is damaged, maintenance and inspection are more difficult.In order to reduce the off-time, reducing the loss stopping production and cause, before doing permanent reparation, emergency first-aid repair should be carried out as early as possible.
Conventional traditional covering leaks clamping is split blade type covering leaks clamping, and be useful in the situation underground pipelines leakage point that do not stop production comparatively large or pipeline when having a moderate finite deformation, its plugging effect is good, and gas, oil pipeline can be applied.If but the less and pipeline of the situation underground pipelines leakage point that do not stop production only have comparatively small deformation time, and still use split blade type covering leaks clamping to go shutoff, the pipeline repairing duration can be incured loss through delay, also can increase maintenance cost simultaneously.
Present patent application proposes one just in this context and is applicable to submerged pipeline leakage bandage watt blocking device.
Summary of the invention
Main purpose of the present invention is the above-mentioned shortcoming overcoming prior art existence, and a kind of blocking device be made up of with locking chain monolithic semicircular arc sealing slips is provided, this blocking device is by sealing the extrusion-deformation of the seal ring had set by slips, an airtight cavity is formed between blocking device and pipeline leakage place, and realize fixing by locking chain to sealing slips, can effectively shorten when not stopping production for pipeline distortion less and pipeline plugging construction duration that leakage point is less, constructing operation is convenient, and construction cost is low.
The object of the invention is to be realized by following technological scheme:
One is applicable to pipeline leakage bandage watt blocking device, it is characterized in that: be provided with shutoff ball valve, sealing slips, seal ring, connecting screw rod, locking chain, wherein said shutoff ball valve and described sealing slips pass through Flange joint, described sealing slips is semicircular arc, bottom surface, described sealing slips top madial wall is provided with seal ring, diagonal angle, described sealing slips two ends is provided with described connecting screw rod, for connecting described locking chain.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, by sealing the extrusion-deformation of the seal ring had set by slips, an airtight cavity is formed between blocking device and pipeline leakage place, and realize fixing by locking chain to sealing slips, can effectively shorten when not stopping production for pipeline distortion less and pipeline plugging construction duration that leakage point is less, constructing operation is convenient, and construction cost is low.
Below in conjunction with drawings and Examples, the present invention will be further described.

Embodiment
Below in conjunction with accompanying drawing and example, the present invention is described in detail.
As Figure 1-3, pipeline leakage bandage watt blocking device involved in the present invention, by shutoff ball valve 1, sealing slips 6, seal ring 9, connecting screw rod 7 and locking chain 8 form, shutoff ball valve 1 is connected by flange 4 with sealing slips 6, sealing slips 6 is semicircular arc, sealing slips 6 both sides are provided with gusset 5, sealing bottom surface, slips 6 top madial wall is provided with seal ring 9, leakage point is in seal ring 9, sealing diagonal angle, slips 6 two ends is provided with connecting screw rod 7, for connecting locking chain 8, pass through tightening nut, locking chain 8 is made constantly to press close to pipeline external wall with sealing slips 6, the seal ring of sealing slips 6 is compressed, be close to pipeline external wall, realize sealing blocking.
Shutoff ball valve 1 is conventional design, and shutoff ball valve 1 is provided with ball valve guard shield 3, and ball valve guard shield 3 upper end is provided with ball valve plug 2, is provided with combination mat between shutoff ball valve 1 and ball valve guard shield 3, and ball valve guard shield 3 and described ball valve plug 2 are provided with combination mat.
For structure of the present invention and application are more clearly described, exemplify following example:
1, remove the anticorrosive coat of blocking device mounting point near submerged pipeline leakage point, polish if desired, guarantee surface smoothing.
2, sealing slips 6 positioning rod on be pull string, the pull string the other end is controlled by workmen on ship, simultaneously by blocking device with lying on shot rope, put into water, blocking device is slided into submerged pipeline leakage point place by diver.When blocking device enters water, locking chain 8 hang over sealing slips 6 on, its one end and connecting screw rod 7 fastening, the other end is in and freely overhangs state.Before blocking device enters water, ball valve plug 2 must be pulled down, install again after blocking device installs.
3, after blocking device is positioned over pipeline leakage point position, locking chain 8 along pipeline lower surface, when will entering water by diver locking chain 8 dangle end and connecting screw rod 7 fastening, after blocking device installs, ball valve plug 2 is contained on blocking device pressure relief opening.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
