Description

Technical Field

[0001] This utility model relates to the field of flange technology, specifically to a four-lobed combined flange. Background Technology

[0002] A flange is a part that connects shafts to each other. It is used for connecting pipe ends, and also for connecting two pieces of equipment at the inlet and outlet. Flanges are widely used in daily life. Traditional flanges are all one-piece molded structures. Although such structures have high strength, they also have drawbacks. Therefore, a composite flange is needed.

[0003] Compared to existing flanges, there are the following drawbacks: insufficient axial tensile strength at the pipe end interface and issues with the strength of the connection between the flange and the plastic composite pipe. This makes construction and installation inconvenient, as it requires fitting onto the pipe body to be connected before use, which reduces the circumferential and axial tensile strength. Additionally, the modular installation can easily lead to poor sealing. Utility Model Content

[0004] The purpose of this utility model is to provide a four-lobed combined flange to solve the following technical problems: insufficient axial tensile strength at the pipe end interface and the strength of the connection with the plastic composite pipe flange, which makes construction and installation inconvenient. Before use, it needs to be fitted onto the pipe body to be connected, which reduces the circumferential and axial tensile strength. At the same time, the combined installation is prone to poor sealing.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] See also Figure 1 , Figure 2 and Figure 4 As shown, this utility model is a four-lobed combined flange, specifically designed for easy construction and installation, eliminating the need to pre-fit the flange onto the pipe to be connected, and increasing circumferential and axial tensile strength. It includes a first connecting flange 1; a second connecting flange 2 located below the first connecting flange 1; a first pipe 3 located inside the first connecting flange 1 and the second connecting flange 2; a second pipe 4 located to the right of the first pipe 3; a first connecting component 7 located on the upper inner side of the first connecting flange 1; a second connecting component 8 located at the connection point of the first connecting flange 1 and the second connecting flange 2; a mating protrusion 12 located at the lower end of the first connecting flange 1; and a mating groove 10 located on the upper inner side of the second connecting flange 2.

[0027] In this embodiment, preferably, the first connecting flange 1 is symmetrically arranged about the center line of the sealing ring 6, and the first connecting flange 1 and the second connecting flange 2 are arranged vertically corresponding about the center line of the first pipe 3. This allows for four-part assembly installation, avoiding the problem of being unable to disassemble the pipe when the first pipe 3 or the second pipe 4 is damaged.

[0028] In this embodiment, preferably, the first connecting assembly 7 consists of an adjusting bolt 701, a rubber ring 702, and an adjusting nut 703. The adjusting bolt 701 is disposed on the inner side of the upper and lower ends of the first connecting flange 1, and a rubber ring 702 is disposed on the outer side of both the left and right ends of the adjusting bolt 701. An adjusting nut 703 connected to the adjusting bolt 701 is disposed on the right side of the rubber ring 702. The adjusting bolt 701 and the rubber ring 702 are connected by a sleeve connection. The adjusting bolt 701 passes through the first connecting flange 1 and the second connecting flange 2 and is connected to the adjusting nut 703 by a thread. This allows the first connecting flange 1 and the second connecting flange 2 to be more stably connected to another unit under the action of the first connecting assembly 7.

[0029] In this embodiment, preferably, a damping rubber block 11 connected to the second connecting flange 2 is provided on the inner side of the mating groove 10. The first connecting flange 1 is connected to the mating groove 10 and the damping rubber block 11 by a snap-fit ​​method through the mating protrusion 12. Both the front and rear ends of the first connecting flange 1 and the second connecting flange 2 are provided with connecting lugs 13, which enable the first connecting flange 1 to be positioned and installed between the mating protrusion 12 and the mating groove 10 opened on the inner side of the upper end of the second connecting flange 2.

[0030] In summary, the first pipe 3 and the second pipe 4 are first placed inside the first connecting flange 1 and the second connecting flange 2 respectively. The mating protrusion 12 fixedly connected to the lower outer end of the first connecting flange 1 is mated and engaged with the mating groove 10 opened on the inner upper end of the second connecting flange 2. This allows the mating protrusion 12 to increase damping under the action of the damping rubber block 11. At this time, the first connecting assembly 7 is used to thread the first connecting flange 1 and the second connecting flange 2 in the lateral position, and the second connecting assembly 8 is used to thread the first connecting flange 1 and the second connecting flange 2 in the longitudinal position. Through the upper and lower groove design, the circumferential and axial tensile strength is increased.

[0031] Example 2

[0032] Reference Figures 1-4The image shows the second embodiment of this utility model. Specifically, after the combined installation, the sealing effect can be enhanced. This includes the inner sides of the inner ends of the first connecting flange 1 and the second connecting flange 2, which are provided with limit grooves 5. A sealing ring 6 is provided on the inner side of the limit groove 5, and a rubber gasket 9 is provided on the inner surface of the first connecting flange 1 and the second connecting flange 2.

[0033] In this embodiment, preferably, the first connecting flange 1 and the second connecting flange 2 are both connected to the rubber inner gasket 9 by adhesive bonding. The longitudinal cross-sectional shape of the first connecting flange 1 and the second connecting flange 2 is "L" shaped, which can securely install the first pipe 3 and the second pipe 4 under the action of the rubber inner gasket 9 and avoid shaking.

[0034] In this embodiment, preferably, both the first connecting flange 1 and the second connecting flange 2 are connected to the sealing ring 6 by a snap-fit ​​method through the limiting groove 5, which can improve the sealing effect under the action of the limiting groove 5.

[0035] In summary, when the first pipe 3 and the second pipe 4 are respectively bonded to the first connecting flange 1 and the second connecting flange 2 through the rubber inner gasket 9, the anti-slip and wear-resistant effect can be increased under the action of the rubber inner gasket 9, thereby improving the damping performance and preventing the first pipe 3 or the second pipe 4 from shifting during later use, which would cause water leakage. In addition, the first connecting flange 1 and the second connecting flange 2 are connected to the sealing ring 6 through the limiting groove 5 by a snap-fit ​​method, which can seal and block the leaking liquid under the action of the sealing ring 6.

[0036] Example 3

[0037] This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0038] The above four-part combination installation and sealing connection not only improves the connection stability and sealing, but also facilitates targeted disassembly and repair in case of damage to the first pipe 3 or the second pipe 4.
