Description

Technical Field

[0001] The utility model relates to the technical field of pressure-type leak-stopping devices for oil pipelines, in particular to a pressure-type leak-stopping device for oil pipelines. Background Art

[0002] An oil pipeline is a pipeline that transports oil or petroleum products. It transports crude oil or petroleum products from oil fields to factories, transfer stations, and ports. Steel pipes are generally used. Oil-resistant hoses or specially treated plastic pipes are sometimes used for short-distance transportation. They are covered with insulation and protective layers. In order to increase the transportation efficiency, when transporting oil, more oil outlets are usually opened on a main pipeline, and then more branch pipes are fixed to carry out branch transportation of oil, so that the transportation of oil can be efficient and convenient.

[0003] In the current production process, it is sometimes necessary to temporarily remove some shunt pipes. When the shunt pipes are removed, the oil outlet holes opened on the main pipeline are generally directly spot welded and sealed. When used later, they are punched with a punching tool. This method firstly consumes more man-hours, is difficult to operate, and increases production costs. Secondly, it is not suitable for large-scale oil transportation sites and greatly reduces the performance. To address this problem, we proposed a pressure leak plugging device for oil pipelines.

[0008] The fixing part is arranged on the surface of the support plate, and the fixing part is used for plugging leaks, which is simple to operate, reduces the production cost and improves the practicability of the device.

[0009] Preferably, a vertical hole is provided on the surface of the moving block, and the vertical hole can ensure the stable movement of the pressing plate.

[0010] Preferably, the fixing member comprises: a gear, the gear is rotatably connected to the surface of the support plate, a cylinder is fixedly mounted on the surface of the gear, and the cylinder rotates synchronously when the gear rotates.

[0011] Preferably, a support block is fixedly mounted on the surface of the cylinder, and a through hole is opened on the surface of the support block. The through hole on the surface of the support block can limit the support rod.

[0014] Compared with the prior art, the utility model provides a pressure-type leak-stopping device for an oil pipeline, which has the following beneficial effects:

[0015] 1. The oil pipeline pressure leak plugging device is provided with a control component. The pressure plate is pressed, and the movable plate fixed on the surface of the pressure plate moves under the support of a spring. The vertical rod fixed on the surface of the movable plate moves outward of the movable block, and the blocking block is stuck in the oil hole. The support rod fixed on the surface of the pressure plate enters the support block.

[0024] The pressing plate 91 passes through the moving block 7 and is slidably connected with the moving block 7. A moving plate 92 is fixedly installed on the surface of the pressing plate 91. The moving plate 92 is slidably connected with the inner wall of the moving block 7. The inner wall of the moving block 7 is fixedly connected with one end of a spring 93.

The vertical rod 94 passes through the moving block 7 and is slidably connected with the moving block 7. A blocking block 95 is fixedly installed on the surface of the vertical rod 94. A support rod 96 is fixedly installed on the surface of the pressing plate 91. The surface of the support rod 96 is hinged with a clamping rod 97. The surface of the clamping rod 97 is fixedly connected with one side of a torsion spring 98. The other side of the torsion spring 98 is fixedly installed on the surface of the support rod 96. A clamping block 99 is fixedly installed on the surface of the support rod 96. A fixing part 910 is provided on the surface of the plate 8. The pressing plate 91 is pressed, and the pressing plate 91 slides in the vertical hole 10. The movable plate 92 fixed on the surface of the pressing plate 91 moves under the support of the spring 93. The vertical rod 94 fixed on the surface of the movable plate 92 moves toward the outside of the movable block 7, and the blocking block 95 is stuck in the oil hole 2. At the same time, when the pressing plate 91 moves, the support rod 96 fixed on the surface of the pressing plate 91 enters the supporting block 9103, and the clamping rod 97 contacts the through hole 9104 and is folded under the support of the torsion spring 98, and enters the supporting block 9103 from the through hole 9104.

The operation is simple, the production cost is reduced, and the practicality of the device is improved.

[0025] A vertical hole 10 is provided on the surface of the moving block 7, and the vertical hole 10 can ensure the stable movement of the pressure plate 91. The fixing member 910 includes: a gear 9101, which is rotatably connected to the surface of the support plate 8, and a cylinder 9102 is fixedly installed on the surface of the gear 9101, and the cylinder 9102 rotates synchronously when the gear 9101 rotates.

When the pressure rod 9106 is subjected to force, it can move under the support of the spring 2 9107.

[0026] In the utility model, when in use, the fixing ring 3 is fixed to the surface of the oil pipeline 1 by bolts. After fixing, the movable ring 6 is moved on the surface of the fixing rod 5 to align the position of the blocking block 95 with the oil hole 2, and then the pressing plate 91 is pressed. The pressing plate 91 slides in the vertical hole 10, and the movable plate 92 fixed on the surface of the pressing plate 91 moves under the support of the spring 93. The vertical rod 94 fixed on the surface of the movable plate 92 moves outward of the movable block 7 to clamp the blocking block 95 into the oil hole 2.
