[0022] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0023] See also Figure 1 The utility model provides an oil branching pipeline for petrochemical industry, including a main pipeline 1 for transporting oil, a flange 2 for easy connection is connected to the left end of the main pipeline 1, and a plurality of groups of branch pipes 3 for branching are connected to the right end, and also includes a movable mechanism 4 arranged at the middle end of the main pipeline 1, and two groups of fixed shafts 5 are arranged up and down at the left and right ends of the movable mechanism 4.

[0024] See also Figure 1-3The utility model provides an oil branching pipeline for petrochemical industry, wherein the movable mechanism 4 comprises a partition plate 41, a through hole 42, a cover plate 43, a guide rod 44 and a movable disk 45. A group of partition plates 41 is installed at the middle end of the main pipeline 1, and a plurality of groups of through holes 42 are opened on the partition plate 41, which can connect the inner left and right ends of the main pipeline 1. A group of cover plates 43 are hinged at the right end of the through hole 42, and a torsion spring is provided at the hinge to facilitate the reset of the cover plate 43, covering and blocking the through hole 42, and a connecting plate 431 is hinged at the right side of the cover plate 43 away from the hinge, and a group of guide rods 44 are provided at the right middle end of the partition plate 41, and a group of movable disks 45 are connected to the outer side of the guide rods 44, and the movable disks 45 can move along the guide rods 44.

[0025] See also Figure 2-5 The utility model provides an oil tapping pipeline for petrochemical industry. A plurality of extension rods 451 are arranged on the outer side of a movable disk 45. The other end of the extension rod 451 passes through a connecting plate 431 and is connected to a group of rollers 452. The rollers 452 can all contact the inner side of the main pipeline 1 to facilitate the movement of the movable disk 45. When the movable disk 45 moves, the connecting plate 431 can move up and down on the outer side of the extension rod 451, thereby adjusting the expansion angle of the cover plate 43 and controlling the opening size of the through hole 42.

[0026] See also Figure 1-6 The utility model provides an oil tapping pipeline for petrochemical industry. A group of rollers 51 are arranged on the outer side of a fixed shaft 5. A plurality of groups of fan blades 52 are arranged on the outer side of the rollers 51 at equal intervals. When the oil flows, the fan blades 52 can drive the rollers 51 to rotate, thereby controlling the flow rate of the oil.

[0027] Here’s how it works:

[0028] The utility model is placed in a suitable position for use. When in use, the main pipeline 1 is connected to the external oil pipeline through the flange 2. The oil flows into the main pipeline 1 from the left end, flows to the right end of the main pipeline 1 through the through hole 42, and finally is discharged through the diversion pipe 3.

[0029] When the oil in the diversion pipe 3 is saturated, the oil accumulates at the right end of the main pipe 1 and pushes the movable plate 45 to move left. Through the action of the extension rod 451 and the torsion spring, the cover plate 43 is gradually reset to reduce the opening size of the through hole 42, limit the oil flow rate, and thus avoid oil backflow. It can change with the amount of oil at the right end of the main pipe 1, and is very practical.
