Abstract
The invention relates to a pipeline leakage double-slip containing cavity plugging device. The device is provided with a plugging slip, a butt joint slip, a double-end stud, a plug, a pressure relief valve and a valve protective cover. Due to the plugging slip with a containing cavity structure, a pipeline leakage protruding area or a pipeline deformation area can be plugged, sealing is achieved through a sealing ring, a leakage point of the portion, where the leakage point protrudes or deformation is serious, of a pipeline is plugged, the maintaining period is short, and construction cost is low.
Description
Technical field
The present invention relates to a kind of blocking device, particularly about a kind of dual-grip cavity volume blocking device leaked for submerged pipeline.
Background technique
Submerged pipeline is the lifeline that offshore oil and gas field is produced, and is a kind of shipping channels the most frequently used in offshore oil gas 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 gas production system.But its shortcoming is pipeline is in seabed, and most pipeline is embedded in certain depth in seafloor soil, once pipeline is damaged, maintenance and inspection difficulty, in order to reduce the off-time, reducing the loss stopping production and cause, before doing permanent reparation, should carry out emergency first-aid repair as early as possible.
Conventional traditional covering leaks clamping is split blade type covering leaks clamping, and the comparatively large or pipeline of the situation underground pipelines leakage point that is applicable to not stop production has moderate finite deformation, and plugging effect is good, and gas, oil pipeline all can be applied, and possesses permanent shut-off capacity.If but had larger projection or pipeline distortion greatly at the situation underground pipelines leakage point that do not stop production, would still use traditional split blade type covering leaks clamping to go shutoff, then cannot meet reparation requirement.
Present patent application proposes a kind of pipeline leakage dual-grip cavity volume blocking device just in this context.
Summary of the invention
Main purpose of the present invention is the above-mentioned shortcoming overcoming prior art existence, and a kind of pipeline leakage dual-grip cavity volume blocking device is provided, realized pipeline leakage elevated regions or the shutoff of pipeline deformation region by the shutoff slips being provided with holding cavity structure, and utilize seal ring to realize sealing, realize in not stopping production situation the pipeline of leakage point existence projection or the leak source shutoff of being out of shape large pipeline, the maintenance duration is short, and construction cost is low.
The object of the invention is to be realized by following technological scheme:
A kind of pipeline leakage dual-grip cavity volume blocking device, it is characterized in that: be provided with shutoff slips, docking slips, stud, plug, pressure relief valve, valve protective cap, wherein said shutoff slips is semicircular arc, described shutoff slips top is provided with keeps away barrier hole, described barrier hole of keeping away is positioned at bottom cavity volume cover platform, described cavity volume cover platform and described valve protective cap pass through Flange joint, it is inner that described pressure relief valve is arranged at described valve protective cap, and be connected with described cavity volume cover platform, described pressure relief valve upper end-hole place is fastened with described plug, described docking slips is connected by described stud with described shutoff slips.
Be provided with seal ring mounting groove bottom described cavity volume cover platform, in described seal ring mounting groove, be provided with several seal ring.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, realized pipeline leakage elevated regions or the shutoff of pipeline deformation region by the shutoff slips being provided with holding cavity structure, and utilize seal ring to realize sealing, realize in not stopping production situation the pipeline of leakage point existence projection or the leak source shutoff of being out of shape large pipeline, the maintenance duration is short, and construction cost is low.
