Description

Technical Field

[0001] The utility model relates to the field of hydraulic connectors, in particular to a hydraulic connector for an oil pipeline. Background Art

[0002] The bow loading system consists of five parts: mooring system, loading manifold system, hydraulic system, control system, and security system. The bow loading system is arranged at the bow of the shuttle tanker. It should be able to successfully connect to the unloading hose on the offshore floating storage vessel (FPSO) or offshore oil platform at an ambient temperature of -20° to 50° on the sea surface, and safely transfer the crude oil to the shuttle tanker through the connecting hose. In order to increase the use length and stability of the connecting hose, a hydraulic connector can be used for connection to ensure that the connected connecting hose can withstand hydraulic pressure.

[0003] However, most of the hydraulic connectors used in oil pipelines have the following problems:

[0004] Existing hydraulic connectors for oil pipelines are mostly connected by bolts through flanges when connecting the oil pipelines. If the oil pipeline needs to be replaced, multiple bolts need to be removed, which is troublesome, time-consuming and labor-intensive, and inconvenient for convenient disassembly and installation of the oil pipeline. At the same time, if the bolts are not tightened during use, leakage may easily occur at the connection. In severe cases, it may easily cause safety hazards, affect the stability of the connection, and make it inconvenient to improve the stability of the sealed connection.

[0005] Therefore, we make improvements to this and propose a hydraulic connector for oil pipelines. Utility Model Content

[0008] A hydraulic connector for an oil pipeline is provided to improve the above problems.

[0009] The specific application is as follows:

[0010] It includes an oil pipeline, a flange is fixedly connected to the oil pipeline, a first sealing gasket is fixedly connected to the flange, a connecting frame is arranged on the flange, a fixing plate is fixedly connected to the connecting frame, a clamping rod is fixedly connected to the fixing plate, a protective shell is fixedly connected to the connecting frame, a clamping slot is provided in the protective shell, a spring is fixedly connected in the protective shell, the other end of the spring is fixedly connected to a limiting plate, a baffle is fixedly connected to the limiting plate, a pull rod is fixedly connected to the limiting plate, a threaded rod is threadedly connected to the connecting frame, and a turntable is fixedly connected to the threaded rod.

[0036] Embodiment 2:

[0037] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0038] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the connecting frames 4 are symmetrically distributed on the left and right sides of the flange 2, and the connecting frames 4 correspond one-to-one with the clamping rods 6 through the fixing plates 5, which can ensure that under the coordinated connection of the connecting frames 4 on both sides, the flange 2 on the oil pipeline 1 can be connected and limited, and it is more convenient to disassemble later, avoiding the time-consuming and laborious disassembly of multiple bolts.

[0039] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the springs 9 are symmetrically distributed on the left and right sides of the protective shell 7, and the springs 9 correspond one-to-one with the baffles 11 through the limit plates 10, which can ensure that the movement of the baffles 11 on both sides can smoothly limit the installation of the clamping rod 6.

[0040] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the limit plate 10 is in contact with the inner side face of the protective shell 7, and the side end face of the clamping rod 6 is inclined with the side end face of the baffle 11, which can ensure that when the limit plate 10 moves, it can move smoothly with the support of the inner side face of the protective shell 7.

[0041] like Figure 4 As shown, as a preferred embodiment, based on the above method, further, the cross-section of the pull rod 12 is "T" shaped, and the length of the pull rod 12 is greater than the length of the baffle 11, which can ensure that by pulling the longer pull rod 12, the baffle 11 can be retracted into the protective shell 7.

[0043] Specifically, the hydraulic connector for oil pipeline is used in combination with Figure 1-8When the oil pipeline 1 is connected and used, the connecting frames 4 on both sides can be spliced ​​on the flange 2 by installing and fixing the flange 2, and the clamping rod 6 on the fixing plate 5 on one side can be inserted into the clamping groove 8 of the protective shell 7. The inclined surface of the clamping rod 6 can push the inclined surface of the baffle 11, driving the baffle 11 and the limit plate 10 to move. When the limit plate 10 moves, it can squeeze the spring 9. After the clamping rod 6 moves, the baffle 11 is not hindered.

[0044] In order to improve the sealing effect between the flanges 2, the rotating disk 14 can be rotated to drive the threaded rod 13 to rotate on the connecting frame 4. When the threaded rod 13 rotates and moves downward, the threaded rod 13 can push the pressure plate 15 to move downward at the same time, and the pressure plates 15 on both sides move downward at the same time, and the pressure plates 15 are in a long arc shape. When moving, they can be supported by the inner side of the connecting frame 4 to move smoothly, and the flanges 2 on both sides can be clamped and limited. A first sealing gasket 3 is provided on the flange 2, which can play a sealing and protective effect when clamped to avoid leakage due to poor sealing. When disassembly is required, only the pull rod 12 needs to be pulled to drive the limit plate 10 to move, and the limit plate 10 drives the baffle 11 to detach from one side of the clamping rod 6 and retract it into the protective shell 7. When the clamping rod 6 is unobstructed, the connecting frames 4 on both sides can be disassembled to improve the disassembly efficiency. After the connection and sealing are completed, the oil pipeline 1 can withstand the hydraulic requirements of high pressure and high flow, and ensure the sealing and reliability of the connection, so as to ensure the safe and efficient operation of the oil transportation system.
