Description

Technical Field

[0001] The utility model relates to the field of oil pipelines, and particularly relates to a petrochemical transportation pipeline. Background Technique

[0002] Petrochemical industry refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. When transporting petrochemical raw materials at ports, transportation pipelines are required. A transportation pipeline refers to a pipeline specifically for transporting liquid and gaseous materials, and the method of transporting materials using a pipeline is called pipeline transportation.

[0003] In order to ensure the sealing of the connection, the existing oil pipelines generally use two groups of flanges and sealing rings for fixed connection. When transporting oil inside the existing oil pipelines, the fine impurities contained in the oil will wear the inside of the pipeline during transportation, causing damage to the inner wall of the pipeline. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a petrochemical transportation pipeline, which can effectively solve the technical problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A petrochemical transportation pipeline includes a connecting pipe and a transportation pipe. A first flange is fixedly arranged on the outer wall of one side of the connecting pipe, and a second flange is fixedly installed on the outer wall of one side of the transportation pipe. A first gasket is fixedly arranged on one side of the first flange. An inner pipe is fixedly arranged on the inner wall of the connecting pipe, and a docking plate is fixedly arranged on the inner wall of the transportation pipe. An anti-wear structure is arranged inside the inner pipe. The anti-wear structure includes an intercepting cylinder installed inside the inner pipe. A liquid inlet hole is opened on one side of the intercepting cylinder, a turning plate is rotatably installed inside the liquid inlet hole, and two groups of limiting rods are fixedly arranged on one side of the intercepting cylinder.

[0007] As a further solution of the utility model, a disassembly structure is installed between the inner pipe and the intercepting cylinder. The disassembly structure includes clamping blocks fixedly installed at the upper and lower ends of the intercepting cylinder and two groups of clamping grooves opened on one side of the inner pipe. A groove is opened on one side of the clamping block, and a trigger plate is fixedly arranged inside the groove.

[0008] As a further solution of the utility model, two limiting inclined plates are fixedly arranged on the inner wall of one side of the intercepting cylinder.

[0009] As a further solution of the utility model, a sealing ring is fixedly arranged on one side of the docking plate, and the other side of the sealing ring is in contact with one side of the inner pipe.

[0010] As a further solution of the utility model, the shape of the trigger plate is rectangular.

[0011] As a further solution of the present utility model, the shapes of the clamping block and the clamping groove are rectangular.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By setting the anti-wear structure, the oil inside the connecting pipe is filtered, avoiding the inner wall of the transportation pipe being damaged by the relatively large amount of impurities in the oil, and better protecting the normal use of the transportation pipe.

[0014] By setting the disassembly structure, after the transportation pipe and the connecting pipe are disassembled, by pulling and pressing the trigger plate with fingers, the interception cylinder can be directly pulled out from one side of the inner pipe, thus realizing quick disassembly. The self-locking turning plate can prevent impurities from flowing out of the liquid inlet hole into the connecting pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-5As shown in the figure, a petrochemical transportation pipeline includes a connecting pipe 1 and a transportation pipe 2. On the outer wall of one side of the connecting pipe 1, a first flange 3 is fixedly arranged. On the outer wall of one side of the transportation pipe 2, a second flange 4 is fixedly installed. On one side of the first flange 3, a first gasket 5 is fixedly arranged. Inside the inner wall of the connecting pipe 1, an inner pipe 7 is fixedly arranged. Inside the inner wall of the transportation pipe 2, a docking plate 6 is fixedly arranged. Inside the inner pipe 7, an anti-wear structure 81 is arranged. The anti-wear structure 81 includes an intercepting cylinder 8 installed inside the inner pipe 7. On one side of the intercepting cylinder 8, a liquid inlet hole 9 is opened. Inside the liquid inlet hole 9, a turning plate 10 is rotatably installed. On one side of the intercepting cylinder 8, two limiting rods 11 are fixedly arranged.

[0023] In this embodiment, a disassembly structure 12 is installed between the inner pipe 7 and the intercepting cylinder 8. The disassembly structure 12 includes clamping blocks 13 fixedly installed at the upper and lower ends of the intercepting cylinder 8 and two card slots 15 opened on one side of the inner pipe 7. On one side of the clamping block 13, a groove 14 is opened. Inside the groove 14, a trigger plate 17 is fixedly arranged.

[0024] The clamping block 13 enters into the inside of the card slot 15, so as to quickly connect the intercepting cylinder 8 and the inner pipe 7. The groove 14 is used to set the trigger plate 17, and the trigger plate 17 facilitates the operator to pull the intercepting cylinder 8.

[0025] In this embodiment, two limiting inclined plates 16 are fixedly arranged on the inner wall of one side of the intercepting cylinder 8.

[0026] The limiting inclined plates 16 are used to limit the turning plate 10.

[0027] In this embodiment, a sealing ring 18 is fixedly arranged on one side of the docking plate 6, and the other side of the sealing ring 18 is in contact with one side of the inner pipe 7.

[0028] The sealing ring 18 is used to ensure the sealing performance of the connection between the inner pipe 7 and the docking plate 6.

[0029] In this embodiment, the shape of the trigger plate 17 is rectangular.

[0030] The rectangular trigger plate 17 is used to facilitate the operator to take out the intercepting cylinder 8.

[0031] In this embodiment, the shapes of the clamping block 13 and the card slot 15 are rectangular.

[0032] It should be noted that the present utility model is a petrochemical transportation pipeline. When in use, when the petroleum is transported from the connecting pipe 1 to the transportation pipe 2, the transported petroleum passes through the liquid inlet hole 9, and the intercepting cylinder 8 intercepts the impurities in the petroleum to prevent the impurities from entering the inside of the transportation pipe 2 and causing damage to the inside of the transportation pipe 2.

[0033] When it is necessary to remove the interception cylinder 8, manually pull the trigger plate 17 to pull the interception cylinder 8 out of the inner tube 7. After being pulled out, the impurities inside the interception cylinder 8 move to one side. When moving, the impurities block the turning plate 10, so that the turning plate 10 automatically closes, avoiding the impurities from returning to the inside of the connecting pipe 1 again, and better realizing the complete removal of the impurities.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
