Description
Technical Field
[0001] This utility model relates to the technical field of pressure vessel connecting flange assemblies, and specifically to a pressure vessel flange assembly with a self-sealing connection structure. Background Technology
[0002] A pressure vessel is a sealed container that can withstand pressure. Pressure vessels have a wide range of applications and play an important role in many sectors such as industry, civil use, military industry, and scientific research. They are most widely used in the chemical and petrochemical industries. Currently, they are generally fixed by connecting the flange cover to the flange with bolts, and the sealing effect is achieved by the sealing gasket placed between the two.
[0003] Existing technologies generally use flat flanges, resulting in a large gap between the connecting flange and the flange cover. This makes the sealing elements prone to aging when exposed to gas for extended periods, thus affecting the sealing performance. Therefore, a pressure vessel flange assembly with a self-sealing connection structure is proposed. Through a butt-joint self-sealing structure, the sealing performance is achieved while reducing the gap between the sealing elements and the gas, thereby extending its service life. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a pressure vessel flange assembly with a self-sealing connection structure. Through the butt-joint self-sealing structure, it achieves sealing while reducing the gap between the sealing element and the gas, thereby improving its service life.
[0005] The technical solution adopted by this utility model to solve its technical problem is a pressure vessel flange assembly with a self-sealing connection structure, including a connecting flange, a connecting hole A, a flange cover, a connecting hole B, a sealing gasket and a snap hole, wherein a self-sealing ring is provided at the center position of one side surface of the connecting flange; A groove is provided on one side of the self-sealing ring, and a sealing ring is provided on one side of the flange cover at the corresponding groove position.
[0006] By adopting the above technical solution, the connecting hole A of the connecting flange and the connecting hole B of the flange cover are used to facilitate the connection and fixation of the two. By connecting the groove on the surface of the self-sealing ring on one side of the flange, the sealing ring of the flange cover can be inserted to achieve a butt-type connection and fixation. This ensures that the sealing gasket on one side of the sealing ring is in the groove, reducing the gap between the seal and the gas, thereby improving its service life. The sealing ring has a hole on its surface to allow the sealing gasket to be snapped into place by the locking block, and the butt joint connection further enhances the stability of the fixation.
[0007] Specifically, the connecting flange has connecting holes A evenly distributed around the center position on one side surface corresponding to the outer periphery of the self-sealing ring.
[0008] By adopting the above technical solution, the connecting hole A on the surface of the connecting flange is used to facilitate the connection and fixation of the flange cover through the connecting hole B.
[0009] Specifically, connection holes B are evenly provided on one side surface of the flange cover corresponding to the position of connection hole A.
[0010] By adopting the above technical solution, the flange cover is used to cover one side of the connecting flange surface.
[0011] Specifically, a sealing gasket is adhered to one side surface of the sealing ring, and the sealing gasket is made of rubber.
[0012] By adopting the above technical solution, a sealing gasket made of rubber material is used to achieve a sealing effect.
[0013] Specifically, the sealing ring has evenly spaced holes around its center position on one side of its outer surface.
[0014] By adopting the above technical solution, the locking holes on the surface of the sealing ring are used to facilitate the locking of the sealing gasket by the locking block.
[0015] Specifically, each of the outer surfaces of one side of the sealing gasket has a locking block at a locking hole position, and the locking block is made of stainless steel.
[0016] By adopting the above technical solution, the groove on the surface of the self-sealing ring on one side of the connecting flange is used to facilitate the insertion of the sealing ring of the flange cover to achieve a butt-to-butt connection and fixation. This ensures that the sealing gasket on one side of the sealing ring is placed in the groove, reducing the gap between the seal and the gas, thereby improving its service life.
[0017] The beneficial effects of this utility model are: (1) The pressure vessel flange assembly with a self-sealing connection structure described in this utility model uses a groove on the surface of the self-sealing ring on one side of the flange to facilitate the insertion of the sealing ring of the flange cover to achieve a butt-type connection and fixation, so that the sealing gasket on one side of the sealing ring is in the groove, reducing the gap between the sealing element and the gas, thereby improving its service life.
[0018] (2) The pressure vessel flange assembly with a self-sealing connection structure described in this utility model uses the card hole on the surface of the sealing ring to make the sealing gasket snap into place and fixed by the card block, and the butt joint connection further improves the fixing stability.

A self-sealing ring 5 is provided at the center of one side surface of the connecting flange 1. A groove 6 is provided on one side of the self-sealing ring 5, and a sealing ring 7 is provided on one side of the flange cover 3 at the position corresponding to the groove 6.
[0023] In use, the flange 1 is connected and fixed by connecting the connecting hole A2 and the flange cover 3 by connecting the connecting hole B4. By connecting the groove 6 on the surface of the self-sealing ring 5 on one side of the flange 1, the sealing ring 7 of the flange cover 3 can be inserted to achieve a butt-type connection and fixation, so that the sealing gasket 8 on one side of the sealing ring 7 is in the groove 6, reducing the gap between the seal and the gas, thereby improving its service life. The sealing ring 7 has a locking hole 9 on its surface so that the sealing gasket 8 can be locked in and fixed by the locking block 10. The butt joint connection further improves the stability of the fixation.
[0024] To extend the service life of seals, for example, such as Figure 1 As shown, the present invention also includes a connecting hole A2 evenly provided on one side surface of the connecting flange 1 around the center position corresponding to the outer periphery of the self-sealing ring 5.

[0031] In use, the sealing ring 7 is secured by the locking holes 9 on its surface, allowing the sealing gasket 8 to be snapped into place by the locking block 10.
[0032] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, the present invention also includes a locking block 10 provided on the outer periphery of one side surface of the sealing gasket 8 at a position of a locking hole 9, and the locking block 10 is made of stainless steel.
[0033] During use, the sealing ring 7 of the flange cover 3 is inserted into the groove 6 on the surface of the self-sealing ring 5 on one side of the connecting flange 1 to achieve a butt-type connection and fixation. This allows the sealing gasket 8 on one side of the sealing ring 7 to be placed in the groove 6, reducing the gap between the seal and the gas and thus improving its service life.
[0034] In use, this utility model connects and fixes the flange 1 through the connecting hole A2 and the flange cover 3 through the connecting hole B4. By connecting the groove 6 on the surface of the self-sealing ring 5 on one side of the flange 1, the sealing ring 7 of the flange cover 3 can be inserted to achieve a butt-type connection and fixation, so that the sealing gasket 8 on one side of the sealing ring 7 is in the groove 6, reducing the gap between the seal and the gas, thereby improving its service life.
