Abstract
A mechanical quick leakage blocking device for line leakage in oil well gathering and transportation pipeline consists of a nut 1, an o-ring seal 2, a cover board 3, an inner lined rubber sheet 4 in the cover board, a screw 5, a joint lever 6 and a stator 7, wherein the screw 5 is provided with the nut 1 and the cover board 3; the end of the screw 5 is connected with the joint lever 6; the stator 7 is connected with the lower end of the screw 5. Being quick and fireproofing, the utility model can be welded and play the role of leakage blocking without closing oil wells, thereby having no influence on production especially oil well production. As the exertion of leakage blocking does not require the close of oil wells, the working time of production equipment can be prolonged and environmental pollution can be reduced.
Description
The blocking device of the pipeline leak source when the utility model relates to the oil well gathering line, specifically, the mechanical type rapid plugging device.
Present gathering line leakage stopping technology has chemistry, also has mechanically, but concerning individual well technology pipeline or long defeated main line, leak stopping all need stop well or stopping production, and the cleaning leak source surface of a wound, then could leak stopping or welding, and it is about more than 2 hours generally to take time.
The purpose of this utility model is to provide a kind of and need not to stop well or stopping production and have mechanical type rapid plugging devices quick, the fire prevention characteristics.
The utility model is achieved in that by nut 1, O-ring seal 2, cover plate 3, cover plate liner rubber 4, screw rod 5, connecting rod 6, fixed plate 7 to be formed, nut 1, cover plate 3 are housed respectively on the screw rod 5, screw rod 5 ends are connected with connecting rod 6, and fixed plate 7 is connected with screw rod 5 lower ends.
The utility model also adopts following technological scheme:
Between nut 1 and the cover plate 3 O-ring seal 2 is arranged.
Cover plate liner rubber 4 is arranged in the cover plate 3.
Fixed plate 7 is two of symmetry and is with barb, its interarea triangularity, and leg-of-mutton both sides are curves, Yi Bian wherein become little convex arc shaped, another side is concave arc shape, forms the barb 3D shape.
Advantage of the present utility model is: have fast, characteristics such as fire prevention, when being applied to the oil well gathering line, then need not to stop well and get final product leak stopping, welding, to producing not influence, particularly to the oil well production well, this leak stopping is owing to need not to stop well, and extremely helpful to the working time that prolongs manufacturing mechanism, the while can also reduce the pollution to environment.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
After gathering line is found leak source, this device is aimed at the leakage eye one push away inward, tightening the screw, the leak stopping operation is promptly accused and is finished.
When being inserted, leakage-baffling device leaks at the moment, the fixed plate 7 of two band barbs of bottom can strut under the effect of elastic force automatically, and hooks tube inner wall when nutting 1, plays a part afterburning, cover plate 3 can be extruded on the outer wall that tightly is attached to pipe when fastening nut 1, thereby blocks leak source.
