The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A temporary pipeline leakage plugging device is shown in figures 1 to 4 and comprises a plugging unit 1, a fixing unit 2 and a driving unit 3, wherein the fixing unit is fixed at a position close to a leakage point of a pipeline 15 to be plugged, the driving unit is installed on the fixing unit, and the driving unit drives the plugging unit to the leakage point;
the fixing unit comprises a base seat 4 and a fixing seat 5 on the base seat, wherein usually, grooves for clamping the pipeline are correspondingly arranged on the base seat and the fixing seat, and the base seat and the fixing seat are fixed through a connecting piece 6 to clamp and fix the pipeline to be blocked; the connecting piece adopts bolt assembly usually, and the skilled person in the art also can select as required, can realize base and fixing base be connected fix on the pipeline can.
The plugging unit comprises a mounting seat 7, a first clamping seat 8 and a second clamping seat 9 are hinged to the mounting seat, a first eave 11 extending outwards is arranged at one end, different from the mounting seat, of a main structure of the first clamping seat, a second eave 12 extending downwards is arranged at one end, different from the mounting seat, of the main structure of the second clamping seat, and a fixing assembly 10 is arranged between the first eave and the second eave.
It should be pointed out that, first, second grip slipper can be through hinged joint, and the two can rotate for the hinge, realizes opening or closing of angle (the angle is opened and is relaxed the centre gripping to the pipeline, when closing, can press from both sides tight pipeline), and it is fixed through fixed subassembly locking between first eaves and the second eaves, can realize first, second grip slipper clamp fastening and fix the pipeline of treating the shutoff.
Generally, the main structure of the first clamping seat and the second clamping seat is semicircular. And all be fixed with pressure pad 13 at first grip slipper major structure inner wall and second grip slipper major structure inner wall, and the pressure pad extends to the eaves department of grip slipper, after first eaves and second eaves press from both sides tightly, the pressure pad on first eaves and the second eaves closely laminates, furthest keeps sealed, and first grip slipper major structure, and the pressure pad part of second grip slipper major structure inner wall can hug closely the pipeline outer wall of treating the shutoff, furthest reduces leakage, win the time for salvageing on next step.
By way of example, the drive unit comprises a drive cylinder fixed to the base, the projecting rod end of the drive cylinder being connected to the mounting seat. Generally, the driving cylinder is an electric cylinder, an air cylinder or a hydraulic cylinder. After the plugging device is pushed to the position right facing the leakage point by using the driving unit, a field operator can pertinently select the self-operation position according to the actual crude oil leakage (or splashing) condition, so that the crude oil is prevented from splashing on the self.
And, constructor arranges the form or arranges the height according to the pipeline, the selection operation position that can be convenient more does benefit to the application of force, for example, when crude oil pipeline is thick higher, the workman is difficult for reaching the pipeline upside and operates, at this moment, can arrange the drive unit in the upside of pipeline, therefore the mount pad of shutoff unit also is in the upside of pipeline, and when such structure was arranged, during field operation, only need to fix the screw up operation of subassembly in the pipeline below can. Through the control of electricity, gas or liquid, can drive the shutoff unit and reach the leakage point, artifical only need the auxiliary operation can, after the leakage point was adjusted well to the shutoff unit, operating personnel screwed up fixed subassembly can.
The pressure pad is usually a rubber pad, an asbestos pad or a nylon pad, but may be made of other materials as required, and preferably an oil-resistant asbestos pad.
The fixing assembly comprises a bolt which sequentially penetrates through the first eaves and the second eaves, a nut 14 is screwed at the screw end of the bolt, and specifically, one bolt can be arranged, or a plurality of bolts can be arranged according to the connection requirement. For locking, a gasket can be arranged between the nut and the eave, and the gasket belongs to the content of the conventional technology in the prior art, so that the detailed description is omitted. Before the plugging unit is pushed to the leakage point, the nut loosens the first eaves and the second eaves first, so that the plugging unit can move conveniently, and in the pushing process, the plugging unit can be manually assisted to shift, and the blockage on the pipeline is avoided.
When the pipeline takes place to leak, when concrete shutoff was used, can install fixed unit near the pipeline leakage emergence position of treating the shutoff earlier, later utilize fixed subassembly to connect the first eaves and the second eaves of shutoff unit, form "pipe clamp structure" around the pipeline, certain clearance is left with the pipeline to first grip slipper and second grip slipper inboard, guarantee that drive unit pushes away the shutoff unit to the leak department smoothly, only need screw the nut of fixed subassembly, can make the clamp of first grip slipper and second grip slipper press from both sides, the grip slipper inner wall pastes the pipeline, can effectively reduce leakage volume, especially when the grip slipper inner wall sets up the pressure pad, more effectively reduce the leakage.
It should be noted that the device is mainly applied to temporary plugging, the plugging effect is good, if leakage is effectively prevented after plugging, the next step of repair can be temporarily omitted, or the device can be directly reinforced at two sides, finally, the structure of the connection part of the driving unit and the plugging unit is detached, and the driving unit and the fixing unit are detached for reuse. Of course, the device does not necessarily require a complete prevention of leakage, and even if there is a small amount of leakage after installation and fixation, it is actually a successful plugging, since the possibility of avoiding leakage enlargement (even pipe explosion) is achieved by the device, and time and opportunities are strived for further pipeline modifications to follow.
Therefore, the pipeline plugging device is reasonable in structural design, can temporarily and quickly realize plugging operation when pipeline leakage occurs, is convenient to operate, saves time and labor, effectively avoids greater loss, and gains time and opportunity for subsequent repair.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
