[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled person in the art without making creative labor belong to the scope of protection of the utility model.

[0017] The utility model will be further described in conjunction with the drawings in the specification.

[0018] The utility model provides the following technical scheme:

[0019] As the attached Figs. 1-2As shown, this utility model discloses a high-strength flat-face welding flange, including a flange body 1. The flange body 1 has a main flange portion 2, a body portion 3, and a secondary flange portion 4. The main flange portion 2 and the secondary flange portion 4 are located at both ends of the body portion 3. A plurality of double reinforcing rib groups are arranged at equal intervals around the central axis of the body portion 3 between the main flange portion 2 and the secondary flange portion 4. Each double reinforcing rib group includes a trapezoidal reinforcing block 5 and reinforcing plates 6 symmetrically arranged on both sides of the trapezoidal reinforcing block 5. The trapezoidal reinforcing block 5 is connected to the body portion 3 and the main flange portion 2, respectively, and the reinforcing plates 6 are connected to the main flange portion 2, the body portion 3, and the secondary flange portion 4, respectively. Specifically, in this design, by setting the double reinforcing rib groups, the structural strength of the flange body 1 is greatly enhanced, enabling it to withstand higher pressures. The design of the trapezoidal reinforcing block 5 not only increases the contact area and improves the stability of the connection, but also effectively disperses stress, preventing damage caused by excessive local pressure. Meanwhile, the multiple connections between the reinforcing plate 6 and the main flange 2, the body 3 and the secondary flange 4 further strengthen the overall structure, enabling the high-strength flat-face welding flange to maintain good sealing performance and durability even under harsh working conditions.

[0020] Furthermore, the trapezoidal reinforcing block 5 has an axial reinforcing portion 14 and a radial reinforcing portion 7. The axial reinforcing portion 14, in a trapezoidal block structure, extends from one end face of the main flange portion 2 along the length direction of the body portion 3. The radial reinforcing portion 7 is located at the bottom end of the axial reinforcing portion 14 near the main flange portion 2. Specifically, in this embodiment, the design of the axial reinforcing portion 14 effectively resists axial tensile and compressive forces, while the radial reinforcing portion 7 enhances the flange's radial load-bearing capacity. This structural design not only improves the strength and stability of the flange but also ensures that the flange maintains its integrity under various complex stress states.

[0021] Furthermore, the main body 3 is cylindrical, and the radial reinforcement 7 extends along the outer wall of the main body 3 to form an arc-shaped block structure. The cross-sectional shape of the radial reinforcement 7 is trapezoidal. Specifically, in this embodiment, the trapezoidal cross-section design of the radial reinforcement 7 further enhances its structural strength, allowing it to better disperse and absorb stress from all directions. This design not only improves the flange's load-bearing capacity but also enhances its durability and reliability under harsh working conditions. Simultaneously, the arc-shaped block structure allows the radial reinforcement 7 to better conform to the outer wall of the main body 3, further enhancing the stability of the connection.

[0022] Furthermore, a lower reinforcing rib structure 8, a middle reinforcing rib structure 9, and an upper reinforcing rib structure 10 are respectively provided between the two end faces of the reinforcing plate 6 and the main flange portion 2, the body portion 3, and the secondary flange portion 4. All three structures are arc-shaped. Specifically, in this embodiment, the design of the lower reinforcing rib structure 8, the middle reinforcing rib structure 9, and the upper reinforcing rib structure 10 not only enhances the connection strength between the reinforcing plate 6 and the main flange portion 2, the body portion 3, and the secondary flange portion 4, but also effectively disperses stress through their arc-shaped structure, preventing damage caused by stress concentration. This combination of multiple reinforcing rib structures greatly improves the overall strength and stability of the flange, enabling it to maintain excellent sealing performance and durability under various extreme working conditions. Simultaneously, the arc-shaped reinforcing ribs can better adapt to the deformation of the flange under stress, further improving the flange's load-bearing capacity and service life.

[0023] Furthermore, a flange channel 11 is formed on the flange body 1, connecting the main flange portion 2, the body portion 3, and the auxiliary flange portion 4. The flange channel 11 has a port portion 12 located within the main flange portion 2 and the auxiliary flange portion 4, and a connecting portion 13 located within the body portion 3. The inner diameter of the port portion 12 is larger than the inner diameter of the connecting portion 13. Specifically, in this embodiment, the design of the port portion 12 having a larger inner diameter than the connecting portion 13 can, on the one hand, effectively prevent the medium from forming eddies in the channel, reducing energy loss; on the other hand, when the flange is under pressure, the larger inner diameter of the port portion 12 can provide a larger support area, dispersing stress and preventing the flange from being damaged due to excessive local pressure.

[0024] Furthermore, the inner diameter of the port portion 12 located within the main flange portion 2 is greater than or equal to the inner diameter of the port portion 12 located within the secondary flange portion 4. Specifically, in this embodiment, the design that the inner diameter of the port portion 12 of the main flange portion 2 is greater than or equal to the inner diameter of the port portion 12 of the secondary flange portion 4 is mainly to accommodate different connection requirements and pressure distributions. The main flange portion 2 often bears the main connection and sealing tasks; therefore, a larger inner diameter of the port portion 12 can provide a larger sealing area, enhance the sealing effect, and also facilitate the smooth flow of the medium. Although the secondary flange portion 4 also plays a connection role, its stress is relatively lighter than that of the main flange portion 2. Therefore, a smaller inner diameter of the port portion 12 can save materials and reduce weight while meeting basic connection requirements.

[0025] Furthermore, the main flange, the body, and the secondary flange are integrally formed by casting.

[0026] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
