Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically a sealing flange. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts. It is used for connecting pipe ends, and also for connecting two pieces of equipment at the inlet and outlet. A sealing flange is an important mechanical component used at the connection of pipes and equipment to achieve a sealed connection. Through a specific structural design, it forms a reliable seal at the flange connection to prevent fluid or gas leakage at the connection and ensure the normal transportation and storage of media inside the pipeline system or equipment.

[0003] The existing flange installation requires multiple people to work together or use related auxiliary tools. The flanges are held up manually or with tools to align them. Then, the mounting holes of the two flanges are aligned by rotation. Finally, another person inserts bolts to fix them. This process is quite cumbersome and requires a lot of time and effort to align the flanges, resulting in low installation efficiency. Utility Model Content

[0004] This utility model provides a sealing flange. Through the sliding fit between the positioning rod and the positioning hole in the connecting mechanism, the flange can be quickly and initially connected, avoiding the cumbersome alignment operation during traditional flange installation, improving installation efficiency, and preventing relative rotation of the first and second flanges during the connection process. This ensures accurate and stable connection of the flanges, reduces installation difficulty, and improves installation quality. By driving the limiting rod to slide within the limiting hole through the moving component, the positioning rod can be locked, further fixing the relative position of the first and second flanges, making the entire installation process more convenient and efficient.

Each set of connecting mechanisms 5 includes a positioning rod 501, a positioning hole 502 and a limiting component. The positioning rod 501 is fixedly arranged on one side of the outer wall of the first flange 1, the positioning hole 502 is opened on one side of the outer wall of the second flange 2, the positioning rod 501 slides through the inner wall of the positioning hole 502, and the limiting component is provided on the second flange 2.

[0031] The fastening mechanism 6 is provided in multiple sets, and each set of fastening mechanism 6 is equidistantly arranged on the second flange 2 along the circumferential direction.

[0032] In this implementation scheme: the mounting ring 3 is used to install and place the sealing gasket 4; the sliding fit between the positioning rod 501 and the positioning hole 502 in the connecting mechanism 5 facilitates the quick docking of the first flange 1 and the second flange 2 and prevents relative rotation between the first flange 1 and the second flange 2; the limiting component is used to limit the sliding of the positioning rod 501 and prevent the positioning rod 501 from separating from the positioning hole 502, which would affect the installation between the first flange 1 and the second flange 2; and the fastening mechanism 6 is used to fasten the first flange 1 and the second flange 2 to ensure the sealing performance of the connection.

[0033] Specifically, each set of limiting components includes a limiting rod 503, a limiting hole 504, and a moving component. The limiting rod 503 is disposed on the moving component, the limiting hole 504 is opened on one side of the outer wall of the positioning rod 501, the limiting rod 503 movably passes through the inner wall of the limiting hole 504, and the limiting rod 503 is slidably engaged with the second flange 2. The moving component is disposed on the second flange 2.

[0034] In this embodiment: the moving component drives the limiting rod 503 to slide within the limiting hole 504, thereby locking the positioning rod 501 and increasing the convenience of connecting the first flange 1 and the second flange 2.

[0035] Specifically, each set of movable components includes a mounting bracket 505, a threaded hole 506, and a threaded rod 507. The mounting bracket 505 is fixedly installed on one side of the outer wall of the second flange 2. The threaded hole 506 is opened on one side of the outer wall of the mounting bracket 505. The threaded rod 507 is threaded to the inner wall of the threaded hole 506, and one end of the threaded rod 507 is rotatably embedded in one side of the outer wall of the limiting rod 503.

[0036] In this embodiment: by rotating the threaded rod 507, which cooperates with the threaded hole 506 on the mounting bracket 505, the limiting rod 503 can be driven into the limiting hole 504.

[0037] Specifically, each fastening mechanism 6 includes a bolt 601 and a nut 602. The bolt 601 moves through one side of the outer wall of the first flange 1 and the second flange 2 in sequence, and the nut 602 is threadedly connected to the outer wall of the bolt 601.

[0038] In this embodiment, the bolt 601 passes through the first flange 1 and the second flange 2 and is fastened by the nut 602. In order to improve the fastening effect, a spring washer or a locking washer can also be provided between the head of the bolt 601 and the nut 602 to prevent the bolt 601 from loosening.

[0039] Specifically, the limiting rod 503 slides through one side of the outer wall of the sealing gasket 4.

[0040] In this embodiment, the position of the sealing gasket 4 is restricted by the limiting rod 503, ensuring that the sealing gasket 4 can be tightly attached between the first flange 1 and the second flange 2 when under pressure, thereby enhancing the sealing performance.

[0043] In use, first, the sealing gasket 4 is movably fitted onto the outer wall of the mounting ring 3 on the second flange 2. The first flange 1 and the second flange 2 are brought close together so that the positioning rod 501 is aligned and slidably inserted into the positioning hole 502. At this time, the first flange 1 and the second flange 2 achieve initial docking through the cooperation of the positioning rod 501 and the positioning hole 502, and avoid relative rotation. Manually rotate the threaded rod 507 to move it in the threaded hole 506. The movement of the threaded rod 507 drives the limiting rod 503 to slide in the limiting hole 504 until the limiting rod 503 is fully inserted into the limiting hole 504 and the positioning rod 501 is locked. At this time, the relative position of the first flange 1 and the second flange 2 is fixed. Then, the bolt 601 is passed through the first flange 1 and the second flange 2 in sequence, and then the nut 602 is threaded onto the outer wall of the bolt 601 to improve the installation efficiency of the flange.
