Abstract
The utility model provides an oil channel plugging structure. The oil channel plugging structure comprises a mandrel; an end cap and a thread are respectively arranged at two ends of the mandrel; a rubber ring and a tapered plug are arranged on the mandrel in a sleeving manner; one end of the rubber ring is matched with the end cap while the other end of the rubber ring is in match with the tapered plug; and a locking nut for fixing the tapered plug is arranged on the thread of the mandrel. The oil channel plugging structure is simple in structure and low in cost; when in use, the locking nut is screwed off, and the rubber ring is plugged into an oil pipe, then the locking nut is screwed to forwards push the tapered plug until the front end of the tapered plug is pressed into the inner wall of the rubber ring; the rubber ring is outwards pressed by a tapered surface of the tapered plug in order to enable the inner wall and the outer wall of the rubber ring to be respectively clung to the inner wall of the mandrel and the inner wall of the oil pipe, and thus the sealing effect is realized; and the oil channel plugging structure is simple and convenient to operate, and has good sealing effect.
Description
Technical field
The utility model belongs to the seal for pipe joints equipment technical field, particularly a kind of oil circuit plugging structure, and it is applicable to the shutoff of the fluidity substance pipelines such as liquid, gas.
Background technique
At present, in hydraulic system, because the change of technique can cause, hydraulic station is transformed.To modifying to pipeline in the hydraulic station transformation, sometimes pipeline is blocked, the pipeline that blocks needs shutoff.Due in pipeline with hydraulic oil, so can not with the welding method shutoff pipeline; In addition, can not on-the-spot tapping, cause the shutoff operation to be difficult to implement.
The model utility content
The utility model provide a kind of simple in structure, be convenient to implement, the oil circuit plugging structure of with low cost and good sealing effect.
For achieving the above object, the technical solution of the utility model is: a kind of oil circuit plugging structure, comprise mandrel, and mandrel two ends are respectively equipped with end cap and screw thread; Be arranged with rubber ring and conical plug on mandrel, rubber ring one end matches with end cap, the other end matches with conical plug, and the screw thread of mandrel is provided with the fixedly locking nut of conical plug.
Be arranged with liner on described mandrel, liner is between rubber ring and end cap.
Described end cap is taper, and conical surface is inside.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises mandrel, and mandrel two ends are respectively equipped with end cap and screw thread; Be arranged with rubber ring and conical plug on mandrel, rubber ring one end matches with end cap, the other end matches with conical plug, and the screw thread of mandrel is provided with the fixedly locking nut of conical plug, it is simple in structure, and is with low cost, during use, first locking nut is unclamped, rubber ring is filled in oil pipe; Then tighten locking nut, conical plug is promoted forward, the conical plug front end is pressed into the inwall of rubber ring, conical surface by conical plug is outwards oppressed rubber ring, makes the inside and outside wall of rubber ring be close to respectively mandrel and tube inner wall, thereby reaches seal action, easy and simple to handle, good sealing effect.
2, be arranged with liner on mandrel, liner can prevent that rubber ring from damaging between rubber ring and end cap, can effectively extend rubber ring working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Oil circuit plugging structure as shown in Figure 1, it comprises mandrel 3, and the two ends of mandrel 3 are respectively equipped with end cap 6 and screw thread, and end cap 6 is taper, and conical surface is towards the inboard.Be arranged with successively liner 7, rubber ring 2 and conical plug 4 on mandrel 3, liner 7 left ends match with the conical surface of end cap 6, and rubber ring 2 right-hand members match with the conical surface of conical plug 4, are provided with the fixedly locking nut 5 of conical plug 4 on the screw thread of mandrel 3.
When the utility model uses, first locking nut 5 is unclamped, rubber ring 2 is filled in oil pipe 1; Then tighten locking nut 5, conical plug 4 is promoted forward, and conical plug 4 front ends are pressed into the inwall of rubber ring 2, outwards oppress rubber ring 2 by the conical surface of conical plug 4, make the inside and outside wall of rubber ring 2 be close to respectively mandrel 3 and oil pipe 1 inwall, thereby reach seal action.
The utility model is applicable to the shutoff of the fluidity substance pipelines such as liquid, gas.
