Abstract
The utility model relates to a wedge-shaped leak stopper for fast plugging in the oil pipeline emergency repair. The wedge-shaped leak stopper is composed of a rubber wedge (5), a protective jacket (3) and a locking mechanism which is composed of a locking screw (2) and a locking handle (4); the circular wedge-shaped rubber wedge (5) is buckled with the protective jacket (3) after being inserted into the pipeline opening of a pipeline to be plugged (1), a plurality of screw holes matched with the locking screw (2) are arranged at the periphery of the protective jacket (3), and screw holes matched with the locking handle (4) are arranged at the bottom center; the direction where the rubber wedge (5) is inserted into the pipeline opening of the pipeline to be plugged (1) is adopted as the front, and a washer (6) matched with the locking handle (4) is adhered at the tail part of the rubber wedge (5). The utility model has the advantages of simplicity, convenient operation, reliability, safety and fast leak stoppage as well as good economical efficiency and practicability.
Description
Technical field
The utility model is the wedge-type leak stopping device of quick blocking in a kind of oil transport pipeline repairing.Relate to the pipe-line system technical field.
Background technique
Blocking technology in the oil transport pipeline repairing is ripe, and existing shutoff equipment at multiple leakage.But conventional shutoff equipment is then still adopted in the shutoff that leads to leakage for drilling hole of oil stolen on pipeline.Adopt existing pipe plugging device cost too high at such stolen repairing, and utilize the space big, the repairing time is long.Because the most low pressure screw thread valves that adopt of drilling hole of oil stolen are installed the stolen valve, the precision of screw thread and not high with the coupling of valve on pipeline.So often be to run oil because of the screw thread place just to find the stolen point.After in repairing, also can only waiting pipeline shutdown not have oil spill to go out the blind head of shutoff could be installed.Obviously, loss is bigger like this.
The model utility content
The purpose of this utility model be in the repairing of a kind of oil transport pipeline of design fast, the wedge-type leak stopping device of reliable, safety, economic shutoff.
The utility model is made up of rubber wedge 5, sheath 3 and locking mechanism, sees Fig. 1.Circle wedge shape (circular cone) rubber wedge 5 is filled in and is buckled sheath 3 behind the mouth of pipe of blocking pipe 1, and the locking nut 2 on the sheath 3 is twisted sheath 3 solid on by blocking pipe 1; The supporting screw of a plurality of and locking nut 2 is arranged around the sheath 3, and there be the screw supporting with set lever 4 in sheath 3 bottom centre; Inserting by the direction of blocking pipe 1 mouth of pipe with rubber wedge 5 is the place ahead, posts the pad 6 supporting with set lever 4 at rubber wedge 5 afterbodys.Locking nut 2 here and set lever 4 constitute locking mechanism.
Wherein sheath 3 is a cup-shaped, and its internal diameter is than bigger by the external diameter of blocking pipe 1, and height is greater than the height of rubber wedge 5; Its material is steel.
This wedge-type leak stopping device links together locking mechanism and Sealing rubber wedge 5 by sheath 3, and has Sealing can guarantee in installation under the oil flow direction, avoids installing because of oily flow problem hinders; By locking nut 2 whole wedge-type leak stopping device is fixed on pipe head,, can increases the frictional force of locking nut 2 and tube wall, guarantee the tight lock of Sealing firmly because pipe head is a screw thread; Utilize set lever 4 that Sealing is pressed down, can pipe head is tight-closed; And Sealing rubber wedge 5 adopts rubber material, because its distortion is big, can guarantee that more sealing is tight.
As seen, the utility model is simple, and is easy to operate, and leak stopping is reliable, safety, quick, and Economy and practicability are good.

Embodiment
Embodiment. embodiment of the present utility model is described and the utility model is further described with this example.This example is the on-the-spot shutoff test that φ 108mm is had the screw thread pipe head, and it constitutes as shown in Figure 1.Its key dimension: circular cone shape rubber wedge 5 small end φ 90mm, hold φ 120mm greatly, high 100mm; Sheath 4 is round aecidioids of external diameter φ 133mm, high 120mm, wall thickness 6mm; At circumferential uniform 6 the M8mm screws in the edge, nearly rim of a cup place of sheath 4, there is the M12mm screw at the center at the bottom of cup; Locking nut 2 is M8 * 50mm screw, and set lever 4 is the screw of M12 * 150mm band swing handle.
This example is tested through on-the-spot shutoff, the shutoff simple installation, and the tight lock of Sealing is firmly, and is tight-closed.Equipment is simple, and is easy to operate, and leak stopping is reliable, safety, quick, and Economy and practicability are good.
