Abstract
The invention discloses an air bag for overhauling a petroleum pipeline. The air bag comprises an air bag body, an air cock arranged on the air bag body and a tee joint connected with the air cock. The air bag further comprises a hose A connected with the position A of the tee joint, a hose B connected with the position B of the tee joint, a ball valve connected to the tail end of the hose A, an air pump connected to the tail end of the hose B, and a pressure sensor electrically connected with the air pump. The pressure sensor is arranged on a pipeline of the hose B. According to the air bag for overhauling the petroleum pipeline, due to the arrangement of the air bag body, petroleum at the two ends of the inside of the air bag body only needs to be fully pumped during first-aid repair, the operating procedure is simple, time and labor are saved, and working efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of air bag, particularly relate to a kind of petroleum pipeline maintenance air bag.
Background technique
In petroleum industry; the longer pipeline of needs laying carrys out the transport for oil; but because petroleum pipeline is laid on comparatively in rugged environment mostly; the situation such as usually there will be seepage, break; need staff to rush to repair in time, repair welding pipeline; but in repair procedures, the oil in whole petroleum pipeline need be drained only, the large and troublesome poeration of workload.
Summary of the invention
Repair the large and defect of troublesome poeration of petroleum pipeline workload for solving, spy of the present invention provides a kind of petroleum pipeline maintenance air bag.
Technological scheme of the present invention is as follows:
A kind of petroleum pipeline maintenance air bag, comprise air bag, the valve be arranged on air bag, the threeway that is connected with valve, 3rd end of threeway is connected with valve, also comprise the flexible pipe A be connected with threeway first end, the flexible pipe B be connected with threeway second end, the pressure transducer also comprise the ball valve be connected on flexible pipe A end, being connected to the gas-filled pump on flexible pipe B end and being electrically connected with gas-filled pump, pressure transducer is arranged on flexible pipe B.
Further, the pull bar be arranged in the both ends of the surface of air bag left and right and the draw ring be arranged on pull bar is also comprised.
Further, described air bag is made up of inner surface layer, mesosphere and external layer, and inner surface layer, external layer are that rubber material is made, and mesosphere is nylon, cotton thread or cord.
Beneficial effect of the present invention is as follows: 1, air bag be arranged so that in repairing, only the oil in the air bag of two ends need be taken out to the greatest extent, programmed sequence of operations is simple, time saving and energy saving, substantially increases working efficiency.
2, the setting of pressure transducer and gas-filled pump can ensure that in air bag, gas is sufficient, and shape invariance, is better fastened in petroleum pipeline.
3, the setting of draw ring is convenient to be extracted out from petroleum pipeline by air bag after petroleum pipeline repairing.
4, the inner surface layer of air bag, external layer are that rubber material is made, wear-resisting and corrosion resistance is higher.Mesosphere is nylon or cotton thread, cord, adds the rigidity of whole utricule, can avoid in rough pipeline, and the excessive deformation of utricule causes being not easy to pull, and also avoids being scratched inner surface layer by pipeline protrusion in use and leaking gas.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of petroleum pipeline maintenance air bag;
Component title wherein corresponding to reference character is as follows:
1-air bag, 2-valve, 3-threeway, 4-flexible pipe A, 5-flexible pipe B, 6-ball valve, 7-gas-filled pump, 8-pressure transducer, 9-pull bar, 10-draw ring, 11-inner surface layer, 12-mesosphere, 13-external layer.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail, but the specific embodiment of the present invention is not limited to this.
Embodiment 1
As shown in Figure 1, a kind of petroleum pipeline maintenance air bag, comprise air bag 1, the valve 2 be arranged on air bag 1, the threeway 3 that is connected with valve 2,3rd end of threeway 3 is connected with valve 2, also comprise the flexible pipe A4 be connected with threeway 3 first end, the flexible pipe B5 be connected with threeway 3 second end, the pressure transducer 8 also comprising the ball valve 6 be connected on flexible pipe A4 end, be connected to the gas-filled pump 7 on flexible pipe B5 end and be electrically connected with gas-filled pump 7, pressure transducer 8 is arranged on flexible pipe B5.
In the present embodiment, when needing to place under repair to the petroleum pipeline destroyed, only air bag 1 need be placed on the two ends of petroleum pipeline, then inflated by gas-filled pump 7 pairs of air bags 1, as long as the oil between two air bags 1 is taken out to the greatest extent, can rush to repair petroleum pipeline, programmed sequence of operations is simple, time saving and energy saving, substantially increases working efficiency.
Pressure transducer 8 is arranged on flexible pipe B5, and when the air pressure in air bag 1 is lower than setting value, pressure transducer 8 will start gas-filled pump 7.Control gas-filled pump 7 makes it quit work higher than during setting value by the air pressure in air bag 1, no longer inflates to air bag 1.The setting of pressure transducer 8 and gas-filled pump 7 can ensure that in air bag 1, gas is sufficient, and shape invariance, is better fastened in petroleum pipeline.
Embodiment 2
The present embodiment, on the basis of embodiment 1, also comprises the pull bar 9 be arranged in air bag about 1 both ends of the surface and the draw ring 10 be arranged on pull bar 9.
Air bag 1, after petroleum pipeline repairing, can be extracted out by pulling draw ring 10 by the draw ring 10 in the present embodiment from petroleum pipeline.
Embodiment 3
The present embodiment is on the basis of embodiment 1 or embodiment 2, and described air bag 1 is made up of inner surface layer 11, mesosphere 12 and external layer 13, and inner surface layer 11, external layer 13 are made for rubber material, and mesosphere 12 is nylon, cotton thread or cord.
In the present embodiment, the inner surface layer 11 of air bag 1, external layer 13 are made for rubber material, wear-resisting and corrosion resistance is higher.Mesosphere 12 is nylon or cotton thread, cord, adds the rigidity of whole utricule 1, can avoid in rough pipeline, and utricule 1 excessively deformation causes being not easy to pull, and also avoids being scratched inner surface layer 11 by pipeline protrusion in use and leaking gas.
As mentioned above, the present invention can be realized preferably.
