Abstract

The utility model relates to a rapid pressurized leakage stopper, in particular to a device which can rapidly stop leakage on the condition that the well is not shut down and the pressure is not relieved, which is composed of a pressurized leakage stopper, a jumper bar and a tapered choke plug. The tapered choke plug is arranged on the jumper bar of the pressurized leakage stopper and then the pressurized leakage stopper is connected with the clip and the straight through valve on the oil pipe; open the valve and press the tapered choke plug into the oil hole of the pipeline through the jumper bar; under the action of outside force, the tapered choke plug is fixedly embedded into the oil hole through the jumper bar to form an interference to help plug up the oil hole. The utility model has a simple structure, a convenient operation and a short leakage stopping time, which has reached the purpose of rapidly stopping leakage on the condition that the well is not shut down and the pressure is not relieved and has solved the defects existing in the current technology.

Description

Quick pressurize leak stopping device

One, technical field

The utility model relates to a kind of quick pressurize leak stopping device, particularly at the device of instantaneous leaking-stopping under the situation of not stopping the well release.

Two, background technique

Along with raising up of International Crude Oil, some lawless persons are on the rise at oil district pipeline drilling hole of oil stolen, give to produce on the crude oil of oil recovery factory and cause immeasurable loss.The unfreezing leak stopping has become the routine work of oil recovery factory, and way commonly used in the past is well have been stopped the unfreezing leak stopping earlier, its shortcoming is to stop well to winter easily to cause pipeline to stop up), this kind way wastes time and energy, or with the gate shutoff in cover, but the easy stolen oil molecule of this method destroys and causes a large amount of leakage of oils.According to above-mentioned two kinds drawback, proposed with a kind of quick pressurize unfreezing leakage-baffling device, promptly under the effect of external force, the taper plug is embedded in the oilhole, the way that the formation interference fit blocks oilhole solves the lawless person at oil district pipeline drilling hole of oil stolen.

Three, summary of the invention

The purpose of this utility model is: quick pressurize leak stopping device, particularly at the device of instantaneous leaking-stopping under the situation of not stopping the well release, solved the purpose of instantaneous leaking-stopping under the situation of not stopping the well release, and overcome the defective that prior art exists.

The technical solution of the utility model is:

(3) one of taper plugs are installed on the jumper bar (2) of pressure sealing device (1), the other end is connected with clamp, throughway valve on the oil pipe, opens valve, taper plug (3) is pressed into the oilhole place of pipeline by jumper bar (2).

The utility model compared with prior art has following technique effect:

1, safety, reliable, easy to use;

2, energy saving;

3, antitheft.

Four, description of drawings:

Accompanying drawing is a plan view of the present utility model;

In the accompanying drawing: leak stopping device (1), jumper bar (2), taper plug (3)

Five, embodiment

Below in conjunction with accompanying drawing in detail the utility model is described in detail.As shown in the figure, the quick pressurize leak stopping device that the utility model provides, the taper plug is contained on the jumper bar of pressure sealing device, after clamp, throughway valve on pressure sealing device and the oil pipe connects then, open valve, with jumper bar the taper plug is pressed into the oilhole place of pipeline, under the effect of external force, jumper bar embeds the taper plug in the oilhole firmly, forms interference fit and blocks oilhole.Mention jumper bar during dismounting earlier, determine that firmly the back is screwing out jumper bar, dismounting pressure sealing device and clamp.With electric welding the taper plug is welded on the pipeline at last.Adopt the artificial and material cost of the stifled a bite well of this new method can save a large amount of expenses in 1 year, the while also significantly reduces the loss of crude oil.

Claims

1, a kind of quick pressurize leak stopping device, particularly at the device of instantaneous leaking-stopping under the situation of not stopping the well release, constitute by leak stopping device (1), jumper bar (2), taper plug (3), it is characterized in that (3) one of taper plugs are installed on the jumper bar (2) of pressure sealing device (1), the other end is connected with clamp, throughway valve on the oil pipe, open valve, taper plug (3) is pressed into the oilhole place of pipeline by jumper bar (2).
