[0002] A flange, often simply called a flange, is a general term that typically refers to a disc-shaped metal body with several holes around its perimeter for fixing and connecting other components. Flanges are widely used in machinery. They are commonly used for connecting pipe ends. To ensure the pipe ends are sealed, a sealing groove is usually cut into the flange end face, and a sealing ring is installed inside the groove. Currently, the sealing ring is usually pressed into the sealing groove manually, which is inconvenient and labor-intensive for workers. Utility Model Content

It should be understood that, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Please see Figure 1-5 This utility model provides a flange sealing ring installation structure, including an upper pressure ring 1 and a lower pressure ring 3 for supporting the flange. The upper end of the lower pressure ring 3 is provided with a support ring 4 that passes through the inner ring of the flange. The upper pressure ring 1 is connected to the support ring 4 by fasteners 5 to achieve the upper pressure ring 1 and the lower pressure ring 3 pressing the flange. The lower pressure ring 3 is provided with an annular groove for placing the sealing ring. A push pressure ring 6 is provided in the annular groove. The upper end of the push pressure ring 6 is used to place the sealing ring. A pushing mechanism is provided at the end of the lower pressure ring 3 opposite to the annular groove. The pushing mechanism is used to push the push pressure ring 6 to move axially toward the upper pressure ring 1 to achieve the sealing ring being pressed into the sealing groove of the flange.

[0020] The lower pressure ring 3 has an annular stepped groove on its inner side. The upper end face of the annular stepped groove is lower than the upper end face of the lower pressure ring 3. The support ring 4 is set on the annular stepped groove. An annular groove is formed between the support ring 4 and the annular stepped groove. The push pressure ring 6 is slidably sleeved on the outside of the support ring 4. The push pressure ring 6 can move along the axial direction of its support ring 4.

[0021] Combination Figure 1-3 As shown, the pushing mechanism includes multiple pushing components 2, which are arranged on the lower pressure ring 3 along its circumference. In this embodiment, there are 12 pushing components 2. Each pushing component 2 includes a fixed base 21 and a pushing bolt 22 disposed on the fixed base 21. The pushing bolt 22 has a threaded portion and is threadedly engaged with the fixed base 21. The threaded portion of the pushing bolt 22 passes through the lower pressure ring 3, extends into the annular groove, and abuts against the pushing pressure ring 6. The 12 pushing bolts are evenly distributed and advance symmetrically in pairs during pushing, ensuring that the pushing pressure ring 6 moves forward slowly and uniformly, avoiding uneven force on the sealing ring or damage due to excessive thrust. It should be noted that any parts not described in detail in this application are prior art.

[0022] Specifically, the fixing base 21 is connected to the lower pressure ring 3 via an inner fixing bolt 24 and an outer fixing bolt 23, and the pushing bolt 22 is located between the inner fixing bolt 24 and the outer fixing bolt 23. The support ring 4 is fixedly connected to the lower pressure ring 3 via the inner fixing bolt 24.

[0023] In addition, there are multiple fasteners 5, which are arranged along the circumference of the upper pressure ring 1. The number of fasteners 5 is 12, and the fasteners 5 are bolts. A Y-shaped reinforcing plate 31 is provided inside the annular stepped groove, and the upper end face of the reinforcing plate 31 is flush with the upper end face of the annular stepped groove.

[0024] This application places the sealing ring into the upper end of the push ring in the annular groove, then places the flange on the outside of the support ring 4 and on the upper end of the lower pressure ring 3, so that the sealing groove of the flange faces the annular groove. Then, the upper pressure ring 1 and the support ring 4 are locked by the fastener 5, so that the upper pressure ring 1 and the lower pressure ring 3 cooperate to press the flange. Subsequently, the pushing mechanism pushes the push ring 6 to press the sealing ring into the sealing groove of the flange, making the installation quick and accurate. During the installation process, the mounting surface of the combined sealing ring is not damaged, the operation is convenient, the labor intensity of workers is low, and the installation efficiency is fast.

[0026] For example, in other embodiments, unlike the embodiments described above, the combination of Figure 4 As shown, the upper end of the push ring 6 is provided with an annular groove for cooperating with the sealing ring. The longitudinal section of the annular groove is arc-shaped. When the sealing ring is placed in the annular groove, the sealing ring protrudes from the annular groove.

[0027] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
