Description

Technical Field

[0001] This utility model relates to the technical field of flange hard seal components, specifically to a flange hard seal component with a preload adaptive adjustment mechanism. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets to connect two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations, while those used on equipment refer to the inlet and outlet flanges of the equipment. Flanges have holes, and bolts are used to tightly connect two flanges.

[0003] Existing sealing flanges all have a sealing ring design. However, sealing flanges on the market are generally composed of three basic structures: upper and lower flanges and sealing rings. In actual use, it often happens that sealing rings are not purchased in sufficient quantities due to omission, which leads to obstacles in the installation process. Furthermore, due to the tight sealing fit between the sealing ring and the sealing groove, it is also difficult to insert them. Utility Model Content

[0004] Technical problems to be solved In view of the above-mentioned shortcomings of the prior art, the present invention provides a flange hard seal assembly with a preload adaptive adjustment mechanism, which can effectively solve the problems in the prior art.

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a flange hard seal assembly with a preload adaptive adjustment mechanism, including a flange and an adjustment assembly disposed within the flange. The inner sidewall of the flange has an annular groove, and a through hole is formed in the annular groove. The adjustment assembly includes a limiting rod, a limiting block fixed to one side of the limiting rod, and a hook ring fixed to the limiting block. The limiting rod is disposed within the through hole, and the bottom end of the hook ring is fixedly connected to the adjustment ring. The adjustment ring is disposed outside the annular groove.

[0006] Furthermore, the through holes are equidistantly arranged in the annular groove, and the limiting rod is a T-shaped structure, with the outer diameter of the end of the limiting rod being larger than the outer diameter of the through hole.

[0007] Furthermore, the middle part of the limiting rod is sleeved with a spring, and the two ends of the spring are fixedly connected to the limiting rod and the annular groove, respectively.

[0008] Furthermore, both the hook ring and the adjusting ring are horizontally placed L-shaped structures, and the bottom end of the adjusting ring is a ring structure with a lower inner side and a higher outer side. The adjusting ring and the hook ring are engaged in a snap-fit ​​connection.

[0009] Furthermore, the inner side of the hook ring and the limiting block are bonded and fixedly connected.

[0010] Furthermore, a platform is provided on one side of the flange, and threaded structures are provided between the platform and the inner wall of the flange.

[0011] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the known public technology: This utility model, through its adjustable component structure, allows the user to pre-fix the structure inside the flange. The limiting rod structure can be locked in the through hole through its T-shaped structure, supporting the outer adjusting ring, limiting block, and hook ring. It is pushed outward by the internal spring, pushing the hook ring outward as well. When the flange comes into contact with the external valve body or other structures, it can first be pressed inward and then pushed outward by the limiting rod structure. Secondly, through the hook ring's low inner and high outer structure, it can contact the side wall of the external structure, achieving a sealing contact function.

[0012] In this device, the hook ring and adjusting ring structures can be hooked and fixed together via an L-shaped structure. The corresponding arrangement of the two sets of structures achieves a hard seal at the flange mating end face, preventing radial movement of the flange. This not only avoids the problem of missing sealing rings during procurement, leading to missing components in assembly, but also reduces the processing cost of the sealing rings. The hook ring has an inclined slope, which not only facilitates matching and insertion with the external tank, but also ensures a smooth surface finish on the sterilization surface, making it difficult for bacteria to slip through the sealing part. The hard-sealing flange ring structure of this utility model is simple and scientifically designed, achieving high sealing and antibacterial performance through a simple structure.

The flange 1 can be fixed by hooking through the L-shaped structure. The corresponding arrangement of the two sets of structures achieves a hard seal on the mating end face of the flange 1, avoiding radial movement of the flange 1. This not only avoids the problem of missing sealing rings during procurement, which would lead to missing components in the assembly, but also reduces the processing cost of the sealing rings. The hook ring 25 is an inclined slope. The inclined slope not only makes it easy to match and insert with the external tank, but also the surface finish of the sterilization surface makes it difficult for bacteria to slide through the sealing part.
