Description

Technical Field

[0001] The utility model relates to the technical field of workpiece manufacturing, in particular to a flange with filtering effect. Background Art

[0002] The connection between pipe fittings is generally achieved by directly welding the two ends of the pipe fittings to the surface of the flange body. The problem is that the welding stress at the welding point between the flange body surface and the pipe fitting is large. During use, the pressure that the welding point can withstand is relatively small, and cracks are prone to occur at the welding point, causing liquid leakage in the pipe fitting. In addition, there are no filter holes on the existing flange body, and the internal liquid between the pipe fittings may contain impurities and cannot be filtered.

[0003] After searching, it is found that a flange device with a filtering structure is disclosed in Chinese patent literature [Application number: CN201620532414.3; Publication number: CN205859419U]. This flange device with a filtering structure includes a flange body and a truncated cone-shaped cylinder, wherein a through hole is provided in the center of the flange body; the truncated cone-shaped cylinder is provided on the through hole; the truncated cone-shaped cylinder is a truncated cone-shaped cylinder with a plurality of filtering holes on the outer wall and one end face; the filtering holes are circular holes, and the diameter of the filtering holes is 5-10 mm; a sealing groove structure is provided at the periphery of the connection between the flange body and the truncated cone-shaped cylinder; at least one mounting hole is evenly provided around the outer edge of the flange body. The utility model can achieve a better filtering effect while playing the role of connecting pipe fittings by providing a truncated cone-shaped cylinder with filtering holes on the through hole of the flange body.

[0004] The device disclosed in the patent forms a truncated cone-shaped cylinder and a flange body by integral casting. When the truncated cone-shaped cylinder or the flange body is damaged and needs to be replaced, the operator can only replace the entire flange together with the truncated cone-shaped cylinder, which makes the maintenance and replacement of the device costly.

The utility model provides structures such as a slider 5, a mounting ring 2, a mounting groove 7 and a fixing ring 4, so that an operator can release the connection effect between the truncated cone-shaped cylinder 3 and the flange body 1 by rotating the truncated cone-shaped cylinder 3, so that an operator can conveniently disassemble the flange body 1 and the truncated cone-shaped cylinder 3. When the flange body 1 or the truncated cone-shaped cylinder 3 is damaged, the utility model can save costs when repairing and replacing the flange body 1 or the truncated cone-shaped cylinder 3, and solves the problem that it is inconvenient to disassemble the flange body 1 and the truncated cone-shaped cylinder 3 due to the existing flange with filtering effect.

[0022] The limit block 9 is arranged in a semicircular structure and is made of polyethylene. In this embodiment, through this design, when the limit block 9 contacts the surface of the slider 5, the limit block 9 can be deformed by its own material and can enter the inner side of the limit groove 10, so that the slider 5 can obtain a limiting effect.

[0023] There are two elastic sheets 13, and multiple elastic sheets 13 are fixed on the upper and lower sides of the surface of the secondary rod body 12. In this embodiment, through this design, after the slider 5 passes through the main rod body 11, the elastic sheet 13 can be deformed and reset, so that the elastic sheet 13 can provide a further limiting effect for the slider 5.

[0024] The diameter of the main rod body 11 is greater than that of the secondary rod body 12, and the diameter of the main rod body 11 is the same as the inner side of the through groove 16. In this embodiment, through this design, the main rod body 11 can be normally inserted into the inner side of the through groove 16 and can fit with the inner wall of the slider 5, so that the limiting effect of the slider 5 can be improved through friction, and the secondary rod body 12 can pass through the through groove 16 normally.

[0025] The main rod body 11 and the secondary rod body 12 are both arc-shaped structures, and the curvature of the main rod body 11 and the secondary rod body 12 is adapted to the curvature of the mounting ring 2. In this embodiment, through this design, it is ensured that the slider 5 can allow the main rod body 11 to normally enter the through groove 16 when sliding.

[0026] A plurality of friction blocks 14 are fixed on the surface of the fixed plate 8, and the friction blocks 14 are made of rubber. In this embodiment, through this design, after the slider 5 moves to the inner side of the main rod body 11, the plurality of friction blocks 14 can contact with the surface of the slider 5, thereby improving the limiting effect of the slider 5 through friction force.

[0027] The surface of the slider 5 is provided with a slide groove 15 for cooperating with the limit block 9. The number of the mounting groove 7, the slider 5 and the insertion groove 6 are six, and they are arranged in a circular array with the center point of the flange body 1 as the center. In this embodiment, through this design, the limit block 9 has enough space to be compressed and deformed through the slide groove 15, and the truncated cone-shaped cylinder 3 can obtain a good limiting effect after being installed with the mounting ring 2 through the fixing ring 4 and the slider 5.

[0028] Working principle: When the truncated cone-shaped cylinder 3 and the flange body 1 need to be installed, firstly, the slider 5 is inserted into the installation groove 7 through the insertion groove 6, and then the truncated cone-shaped cylinder 3 is held and rotated to make the slider 5 gradually rotate toward the main rod body 11 inside the installation groove 7. When the slider 5 rotates to the point where the through groove 16 contacts the surface of the main rod body 11, the limit block 9 will first contact the surface of the slider 5 through the slide groove 15 and deform. When the slider 5 rotates to the point where the secondary rod body 12 is located inside the through groove 16, the elastic sheet 13 will be compressed and deformed when the slider 5 rotates to the point where the secondary rod body 12 is located inside the through groove 16. 2, the limiting block 9 will be located inside the limiting groove 10, and the elastic sheet 13 will rebound to restore the slider 5, so that the slider 5 can obtain the limiting effect, so that the slider 5 is not easy to move inside the installation groove 7, thereby completing the installation operation of the flange body 1 and the truncated cone-shaped cylinder 3. When it is necessary to disassemble the truncated cone-shaped cylinder 3 from the flange body 1, the operator only needs to rotate the truncated cone-shaped cylinder 3 in the opposite direction, and then take the truncated cone-shaped cylinder 3 and the slider 5 out of the installation groove 7 through the insertion groove 6, so as to complete the disassembly operation of the truncated cone-shaped cylinder 3 from the flange body 1.
