Description
Technical field
The utility model relates to a kind of oil tube repair blocking device, belongs to oil field, relates in particular a kind of capping of oil pipe flange plate interface.
Background technique
Oil transport pipeline is after permanent use, erosion damage due to external environment condition and inner oil, usually can there is the problem of leakage and booster in pipeline, when there is leakage and booster, all generally first to close oil transportation switch, and then the repairing pipe or the removal that damage, and when repairing pipe or removal, just the petroleum pipeline mouth of pipe shutoff at the two ends that are connected with damage pipeline can need to be carried out to operation, in order to avoid cause Oil spills in pipe, also can prevent that irrelevant staff from opening oil transportation switch in unwitting situation simultaneously, thereby cause the accident, shutoff is in the past to adopt the plate-like end cap adapting with transport pipe nozzle flange dish that the mouth of pipe is blocked mostly, but this plate-like end cap needs a plurality of bolts to fix, plate-like end cap weight is heavier, in handling, just need people more than two people to cooperate, and also need spanner to assist, manpower and materials have not only been wasted, increased the repair time, handling are simultaneously trouble comparatively, it is also very inconvenient to carry.
Model utility content
The utility model provides a kind of capping of oil pipe flange plate interface, has solved blocking device in the past and has used inconvenience, waste of manpower and the problem of time.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: a kind of capping of oil pipe flange plate interface, comprise seal disc and activity card column, activity card column is by the rotating seal disc circumference side that is connected to of rotatingshaft, in described activity card column, tapped through hole is set, in tapped through hole, be provided with clamping double-screw bolt, clamping double-screw bolt upper end portion is provided with knob; Described seal disc upper-end surface is provided with interface slot, and described seal disc middle part is provided with earial drainage tapped hole vertically.
On described knob, be horizontally arranged with through hole.
Clamping end, double-screw bolt lower end is spherical structure.
Described seal disc is provided with seal groove in interface slot bottom.
Described activity card column is circularly and evenly distributed four centered by seal disc axis.
Compared with prior art, the beneficial effects of the utility model are: the capping of this oil pipe flange plate interface of the utility model design, and not only simple in structure, clamping is convenient, loads and unloads all very conveniently, has saved man power and material, shortened the repair time, practical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Label in figure is expressed as: 1, activity card column; 2, rotatingshaft; 3, seal groove; 4, interface slot; 5, earial drainage tapped hole; 6, seal disc; 7, knob; 8, through hole; 9, clamping double-screw bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1
The capping of a kind of oil pipe flange plate interface as shown in Figure 1, comprise seal disc 6 and activity card column 1, activity card column 1 is by the rotating seal disc 6 circumference sides that are connected to of rotatingshaft 2, in described activity card column 1, tapped through hole is set, in tapped through hole, be provided with clamping double-screw bolt 9, clamping double-screw bolt 9 upper end portions are provided with knob 7; Described seal disc 6 upper-end surfaces are provided with interface slot 4, and described seal disc 6 middle parts are provided with earial drainage tapped hole 5 vertically.
When the present embodiment is used, rotate moving axis 2 of activity card column 1 is rotated, the interface slot of seal disc 64 place end faces are vacated, corresponding oil pipe flange plate interface is by seal disc fastening, now flange plate interface is clamped in interface slot 4, the moving axis 2 that again activity card column 1 rotated rotates, make activity card column 1 correspondence at the back side of flange plate interface, by knob 7, screw activity card column 1 activity card column 1 is clamped on to the flange plate back side, thereby seal disc 6 is clamped on flange plate interface completely, reach plugging effect, thereby can damage the maintenance of oil pipe, can not cause leakage, in earial drainage tapped hole 5, can screw screwed pipe joint, thereby the unnecessary oil in oil pipe can be gushed, in order to avoid booster, also can on screwed pipe joint, connect oil hose simultaneously, oil hose connects normal transport pipe, to guarantee also normally oil transportation when overhauling, assurance oil transportation is normal, without disconnecting oil transportation switch, and only need can guarantee sealing at earial drainage tapped hole 5 inward turning tightening seal plugs when not needing to connect oil hose, the present embodiment, by above structure, not only can reach the shutoff of petroleum delivery pipeline easily, easy to loading and unloading during use, blocks effectively, and a people can complete handling, saved man power and material, and handling fast, shortened the repair time, practical.
Embodiment 2
The present embodiment has been optimized following structure on embodiment 1 basis: on described knob 7, be horizontally arranged with through hole 8.
The present embodiment is in order to make seal disc 6 clampings firmly, and convenient clamping double-screw bolt 9 clampings, the special through hole 8 that is horizontally arranged with on knob 7, maintainer can use iron to pass through hole 8 and form lever when screwing or unscrewing clamping double-screw bolt, by rotating iron, screw or unscrew, can reach labour-saving object, improve handling speed, reduce handling difficulty.
Embodiment 3
The present embodiment has been optimized clamping double-screw bolt on embodiment 1 or embodiment's 2 basis, is specially: described clamping double-screw bolt 9 ends, lower end are spherical structure.
In the present embodiment for seal disc 6 is firmly stressed when clamping double-screw bolt 9 clamping, and reach good sealing effect, therefore spherical structure is arranged to in clamping double-screw bolt 9 ends, lower end, when spheric structure contacts with flange plate when clamping double-screw bolt 9 clamping like this, just can there is not the problem that clamping lost efficacy because clamping double-screw bolt 9 has certain tilt angle with flange plate, make to clamp double-screw bolt 9 no matter with flange plate angle how, can guarantee to clamp the clamping effect of double-screw bolt 9, seal disc 6 is firmly clamped, clamp effective, strong adaptability.
