A high-strength oil transportation pipeline connection component

Abstract

This utility model relates to the field of oil transportation pipelines, specifically to a high-tightness oil transportation pipeline connection assembly. It includes two supports placed at both ends of the oil pipeline, with multiple inclined support rods rotatably connected to the supports, the ends of which push the adjacent flanges outwards. The advantages of this utility model compared to existing technologies are: at the connection point of adjacent oil pipeline fittings, this assembly provides two tightly fixed flanges on both sides, each with a set of rotatable support rods. The ends of the support rods press tightly against the inner side of the flanges, and the outward expansion of the oil inside the pipe causes the support rods to move closer together. The force carried by this force further tightens the two flanges together, preventing the pipeline from being damaged or leaking due to excessive oil pressure at the connection point.

Description

Technical Field

[0001] This utility model relates to the field of oil transportation pipelines, specifically to a connecting component for oil transportation pipelines with strong fastening properties. Background Technology

[0002] Pipelines are a mode of oil transportation. They connect sections of oil pipelines to provide a path for the flow of oil.

[0003] Oil pipelines are typically joined together using flanges. By pressing two flanges together, gaps are eliminated between the ends of the pipelines. Sometimes, welding is also used for reinforcement to seal the pipelines.

[0004] Oil is continuously transported in pipelines. Due to the power source of the liquid flow during transportation, the pipeline is filled with oil and is under high oil pressure at all times, making it easy for oil to leak at the joints of the pipe units. Existing flange assembly methods are likely to be damaged under long-term pressure inside the pipe, which will reduce their sealing performance. Replacing pipe fittings in oil pipelines is very troublesome and will cause significant economic losses. Therefore, a high-tightness oil transportation pipeline connection component is provided. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that conventional flange assembly methods are prone to damage and oil leakage after prolonged exposure to oil pressure within the pipe.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a strong oil transportation pipeline connection assembly, including an oil pipeline and a support bracket for supporting the oil pipeline. Both ends of the oil pipeline are connected to flanges, and multiple sets of bolts are evenly arranged on the flanges to connect adjacent oil pipelines to each other.

[0009] Multiple support rods with inclined placement and ends embedded inside the flange are rotatably connected to the outer sides of both ends of the oil pipeline. Multiple abutment rods with hemispherical tops are connected to the outer side of the oil pipeline. The top of the abutment rods contacts the bottom surface of the support rods. Under high oil pressure, the force transmitted outward by the expanding oil pipeline causes the support rods to move towards the flange under the upward pushing action of the abutment rods.

[0010] Furthermore, brackets two are placed on both sides of bracket one, and support shafts are connected to the top of bracket two around all four sides. The end of the support rod away from the flange is rotatably connected to the support shaft.

[0011] Furthermore, multiple reinforcing ribs are provided on the inner side of the flange and the oil pipeline for connection.

[0012] Furthermore, the flange is evenly provided with multiple through holes for bolts to pass through, and the through holes, support rods, and reinforcing ribs are arranged alternately on the flange.

[0013] III. Beneficial Effects

[0014] The advantages of this invention compared to the prior art are as follows: At the connection of adjacent oil pipeline fittings, the component consists of two tightly fixed flanges on both sides, each provided with a set of rotatable support rods. The ends of the support rods are tightly pressed against the inner side of the flanges, and the outward expansion of the oil inside the pipe causes the support rods to tend to move closer to each other. The force carried by this makes the two flanges press together more firmly, preventing the pipeline from being damaged or leaking due to excessive oil pressure at the connection.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a high-strength oil transportation pipeline connection component, combined with the attached... Figure 1-3It includes an oil pipeline 1 and a support bracket 2 that provides support for the oil pipeline 1. Both ends of the oil pipeline 1 are connected to flanges 3. Multiple sets of bolts are evenly provided on the flanges 3 to connect adjacent oil pipelines 1 to each other. Multiple through holes 4 for bolts to pass through are evenly provided on the flanges 3.

[0024] An oil pipeline consists of multiple identical oil pipes 1 arranged in sequence and spliced ​​together to provide a path for oil transportation. Both ends of the pipeline have flanges. Bolts are used to pass through the through holes 4 of the flanges 3 at the ends of two adjacent oil pipes 1 in sequence. The two flanges 3 are pressed together by the threaded connection of the nuts on the bolts. Welding can also be used to achieve better sealing and fixed connection.

[0025] Combined with appendix Figure 4 The oil pipeline 1 has multiple support rods 9 rotatably connected to its outer ends at both ends, which are placed at an angle and whose ends are embedded inside the flange 3. Support brackets 7 are placed on both sides of the first bracket 2, in conjunction with the attached... Figure 6 The bracket 7 is provided with support shafts 8 around its top, and the end of the support rod 9 away from the flange 3 is rotatably connected to the support shafts 8.

[0026] The second bracket 7 and its carried components are the main connecting units in this assembly. It is also placed on the ground together with the first bracket 2. Its top has a frame that fits around the end of the oil pipe 1. Multiple support rods 9 are evenly distributed around the center of the oil pipe 1. The support rods 9 are rotatably connected to the second bracket 7 and are tilted at a certain angle towards the center. The other end is pressed tightly against the inner surface of the flange 3. It is first embedded in the inner side of the flange 3, and the path of outward rotation is blocked by the flange 3, so it will not detach from the oil pipe 1.

[0027] Combined with appendix Figure 5 The outer side of the oil pipeline 1 is connected with a plurality of abutment rods 6 with hemispherical tops. The top of the abutment rods 6 contacts the bottom surface of the support rod 9. Under high oil pressure, the force transmitted outward by the expanding oil pipeline 1 causes the support rod 9 to move towards the flange 3 under the upward pushing action of the abutment rods 6.

[0028] When the oil pressure inside the pipe suddenly increases, the pipe wall will tend to expand outward. The force that causes this tendency is transmitted outward through the abutment rod 6, whose extension direction is perpendicular to the axial direction of the oil pipe 1. It will push the support rod 9 mounted at its top upward. Then, the support rod 9 in the rotating mounting bracket 2 7 will have a tendency to rotate outward. Since its end is locked inside the flange 3 and is blocked, it cannot complete the outward rotation driven by the force, which will create a strong squeezing effect on the flange 3.

[0029] When the two oil pipelines 1 are connected to each other, each is equipped with a connection unit mainly composed of the support 7. The flanges 3 on the opposite sides are tightly supported by a support rod 9 that has an outward rotation tendency. The support rods 9 on both sides of the connection forcefully clamp the flanges 3, effectively improving the stability and sealing of the connection between the pipelines.

[0030] Multiple reinforcing ribs 5 are provided on the inner side of the flange 3 and the oil pipeline 1, and the through hole 4, support rod 9, and reinforcing ribs 5 are arranged alternately on the flange 3.

[0031] In a specific implementation of this utility model, the oil pipeline is assembled into a whole through the oil pipeline 1. When transporting oil inside the pipeline, the oil inside will always push against the inner wall of the oil pipeline 1, generating an outward force.

[0032] When the oil is pressurized outward at the connection of adjacent oil pipes 1, it also applies almost the same pressure outward towards the pipe wall of oil pipe 1 with the abutment rod 6. The abutment rod 6 transmits the outward force, causing the support rod 9, which is placed at its top and kept in an inclined state, to have a tendency to rotate outward. Under this tendency, the support rods 9 on both sides of the pipe connection also have a tendency to move in the opposite direction towards the flange 3. The force under this tendency further clamps the two flanges 3, preventing the oil squeezed outward from inside the pipe from breaking through the flange assembly and causing oil leakage.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
