Abstract

The utility model discloses a kind of plugging device for non-adherent flexible pipe bulge test, including:Block flange, plugging device end plate and sealing ring, the closure flange uses U shape structure, there is the screw thread for connecting pipe joint inner side, the closure end plate uses " convex " font structure, leave the screwed hole for being available for installing valve in centre, outer ring is provided with through hole, and the closure flange and the closure end plate can be mounted to together by bolt.When progress pipeline dispatches from the factory pressure check, good sealing effectiveness can not only be reached, Valve controlling water injection rate can also be installed in the neutral threaded hole of closure end plate, obtain accurate result of the test, so as to grasp the performance of pipeline exactly, this is simple in construction, and manufacturing cost is low, easy to operate.

Description

A kind of plugging device for non-adherent flexible pipe bulge test
Technical field
The utility model belongs to conveyance conduit performance detection field, particularly a kind of non-adherent flexible pipe exfactory inspection The plugging device of bulge test.
Background technology
At present, in the recovery process of Marine oil and gas resource, submarine pipeline conveying is still main mode of movement, and it has There are the series of advantages such as freight volume is big, the haul-cycle time is short, conevying efficiency is high.
Due to the abominable of pipeline military service marine environment and the double influence of complexity, the damage and leakage of pipeline, not only Very big economic loss can be brought to enterprise, it is often more important that serious destruction can be brought to marine environment and natural, ecological.Cause This, the exfactory inspection to submarine pipeline is current oil recovery business issues that need special attention, and exfactory inspection also has very important Meaning.
Pipeline is in conveying oil, gas and water or mixed defeated medium, it is necessary to have certain bearing capacity.Therefore bulge test is made For the checking procedure that submarine pipeline exfactory inspection is essential, and the sealing effectiveness of plugging device is accurate to the experimental data of bulge test True property influences very big.Published plugging device is applied in pipe laying and maintenance process, is fixed by internal-expansion type, wedge shape increases The structures such as power locking, the linkage sealing of oil cylinder group, do not stop to realize pipe plugging under the operating mode of pressure in pipe oil gas.If it is used for pipeline Bulge test, compare for its is complicated, manufacturing cost is high, and simply carries out sealing function to pipeline, can not pacify Fill valve.And in bulge test, it is necessary to the pressure suppressed in strict control pipeline, therefore it is not appropriate for pipeline bulge test.
Present patent application exactly proposes a kind of plugging device for non-adherent flexible pipe bulge test in this context.
The content of the invention
The utility model is in view of the deficienciess of the prior art, propose a kind of envelope for non-adherent flexible pipe bulge test Stifled device.
Of the present utility model realized by following technical scheme:
A kind of plugging device for non-adherent flexible pipe bulge test, including:Block flange, closure end plate
And sealing ring, the closure flange use U shape structure, there are the screw thread for connecting pipe joint, institute in inner side State closure end plate and use " convex " font structure, the screwed hole for being available for installing valve is left in centre, and outer ring is provided with through hole, the closure Flange and the closure end plate can be mounted to together by bolt.
The sealing ring is placed between the closure flange, the closure end plate and the pipe joint to be attached again, Good sealing effectiveness can be played.
The beneficial effects of the utility model:The utility model is by blocking the U shape structure of flange with blocking end plate " convex " font structure, and sealing ring serve sealing effectiveness well;The neutral threaded hole of closure end plate can install valve, Water injection rate is controlled during experiment.Not only good sealing effectiveness can have been reached but also water injection rate can be controlled, accurately tested As a result, so as to grasp the performance of pipeline exactly, this is simple in construction, and manufacturing cost is low, easy to operate.
The utility model is described further with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the profile that the utility model plugging device is installed to non-adherent flexible pipe joint;
Fig. 2 is the utility model plugging device structural representation.
Wherein:1- bolts;2- blocks end plate;3- sealing rings;4- blocks flange;5- joints.
Embodiment
Below in conjunction with the accompanying drawings and example, the utility model is described in detail.
As shown in Figure 1-2, a kind of plugging device for non-adherent flexible pipe bulge test, including:Closure
Flange 4, closure end plate 2 and sealing ring 3, the closure flange 4 use U shape structure, and inner side has for connecting The screw thread of pipe joint 5 is tested, the closure end plate 2 uses " convex " font structure, and the screwed hole for being available for installing valve is left in centre, Outer ring is provided with through hole, and the closure flange and the closure end plate can be mounted to together by bolt 1.
The sealing ring 3 is placed between the closure flange 4, the closure end plate 2 and the experiment pipe joint 5 to carry out again Connection, can play good sealing effectiveness.
A kind of use principle of plugging device for non-adherent flexible pipe bulge test of the present embodiment is as follows:
Before on-test, experiment pipe joint 5 is installed in place first, then connect at the center for blocking flange 4 with developmental tube First 5 center alignment, it will block flange 4 using screw thread and be tightened on experiment pipe joint 5;Then sealing ring 3 is filled in into plugging method In blue 4 grooves;The part for the part inlay that protrudes of end plate 2 will be blocked entering to block flange 4 again and falling in, as shown in Figure 2;Use bolt 1 insertion closure end plate 2 is tightened with blocking the connecting hole of flange 4, as shown in figure 1, reaching connection status;
Then valve is installed on plugging device end plate by blocking the screwed hole of the centre of end plate 2;Make pipeline left end valve Door is connected with booster pump, and the valve of right-hand member is with dividing gas bag to be connected, you can carries out bulge test to pipeline.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal Limitation, every any simple modification made according to the technical essence of the utility model to above example, equivalent variations with Modification, in the range of still falling within technical solutions of the utility model.
