Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pressure-resistant industrial pipeline connection component. Background Art

[0002] Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange gaskets between the two flange plates, and fasten them together with bolts to complete the connection.

[0003] Flange connection is an important connection method for pipeline construction. Its sealing surface includes smooth, concave and convex, and tongue and groove types. Among them, the smooth type is the most widely used. Flange connection is suitable for pressure-resistant environment. It is simple, reliable, and durable. It can withstand higher pressure or vacuum. However, the current smooth flange connection structure is relatively simple (as mentioned above). After the flange gasket is squeezed and fixed, the flange gasket will produce a certain deformation. Although it can maintain effective sealing for a period of time, the life span is reduced over time, and both the inside and the outside will age and cause leakage. Frequent replacement and maintenance will increase workload and reduce production efficiency. Therefore, we propose a pressure-resistant industrial pipeline connection component. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, but the current smooth flange connection structure is relatively simple (as mentioned above). After the flange gasket is squeezed and fixed, the flange gasket will produce a certain deformation. Although it can maintain an effective seal for a period of time, the life span is reduced over time, and both the inside and the outside will age and cause leakage. Frequent replacement and maintenance will increase the workload and reduce production efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pressure-resistant industrial pipeline connection assembly includes a flange connected to the pipeline and a flange gasket located between two flanges for sealing. The flange gasket is integrally formed with a sealing ring portion on the periphery, and the corresponding outer edges of the two flanges after docking are sealed by the sealing ring portion. A reinforcement ring is provided on the periphery of the flange, and the sealing ring portion is sealed by the reinforcement ring. The opposite ends of the two reinforcement rings are respectively provided with a circular groove and a convex ring for docking.

[0007] Furthermore, an outer periphery of the flange is provided with an external threaded portion, and the external threaded portion is arranged away from the sealing ring portion.

[0008] Furthermore, an internal threaded portion is provided on the periphery of the reinforcement ring corresponding to the external threaded portion, and the reinforcement ring is threadably connected to the flange through the external threaded portion and the internal threaded portion.

[0009] Furthermore, the sealing ring portion is a multi-layer ring, and the multi-layer ring is stepped from the outer edge of the flange gasket to the outside.

[0010] Furthermore, an inner wall of the reinforcement ring is provided with an embedded groove corresponding to the sealing ring portion, the embedded groove is stepped to match the multi-layer ring shape of the sealing ring portion, and the thickness of the reinforcement ring is the same as that of the flange.

[0011] Furthermore, the flanges are fixed by bolts.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, on the basis of the original two flanges being fixed and fastened, a reinforcement ring design is added, and the flange gasket is designed. The corresponding outer edges of the two sets of flanges after being butted are sealed by the sealing ring part. With the stepped design and after the reinforcement ring is installed, the sealing ring part is squeezed and fixed, so as to further seal the corresponding outer edges of the two sets of flanges after being butted. The two sets of reinforcement rings are threadedly connected on the flange for butt connection. The installation is convenient and the structure is simple. The flange gasket is effectively built-inly protected to avoid external influences on the flange gasket. The sealing ring part and the embedded groove greatly improve the clamping stability, further improve the sealing effect of the flange gasket, and improve the overall life of the flange connection. The replacement frequency is reduced, and the possibility of leakage is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a pressure-resistant industrial pipeline connection assembly, comprising a flange 1 connected to the pipeline and a flange gasket 2 located between the two flanges 1 for sealing, a sealing ring portion 21 is integrally formed on the periphery of the flange gasket 2, the sealing ring portion 21 and the flange gasket 2 are integrally formed, and the corresponding outer edges of the two flanges 1 after docking are sealed by the sealing ring portion 21, a reinforcement ring 3 is sleeved on the periphery of the flange 1, and the sealing ring portion 21 is sealed by the reinforcement ring 3, and the opposite ends of the two reinforcement rings 3 are respectively provided with a circular groove 31 and a convex ring 32 for docking, and the circular groove 31 and the convex ring 32 are docked to improve the installation stability and avoid shaking.

[0024] Example 2

[0025] like Figure 1-3 As shown, the outer periphery of the flange 1 is provided with an external threaded portion 11, which is arranged away from the sealing ring portion 21, so that the sealing ring portion 21 contacts the outer smooth portion of the flange 1, thereby ensuring the sealing effect.

[0026] An internal thread portion 33 is provided on the periphery of the reinforcement ring 3 corresponding to the external thread portion 11 , and the reinforcement ring 3 is threadedly connected to the flange 1 through the external thread portion 11 and the internal thread portion 33 to complete the installation.

[0027] The sealing ring portion 21 is a multi-layer ring, the number and size of the layers are designed according to demand, and the multi-layer ring is stepped from the outer edge of the flange gasket 2 to the outside. The stepped design makes the multi-layer ring flange gasket 2 narrower in sequence, thereby improving the sealing effect into multiple stages and increasing the contact area.
