Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to a fluororubber O-ring. Background Technology

[0002] In modern industrial systems, sealing technology is crucial for ensuring stable equipment operation and preventing media leakage. Fluororubber O-rings, as a core component in the sealing field, play an indispensable role in numerous industries due to their unique material properties and structural advantages. Fluororubber, a synthetic polymer elastomer containing fluorine atoms in its main or side chains, has revolutionized sealing materials since its introduction in the 1950s with its superior performance. The high bond energy of the CF bonds in its molecular structure gives fluororubber many advantages unmatched by traditional rubbers. From a chemical stability perspective, fluororubber exhibits extremely strong resistance to most chemicals, such as common strong acids, strong alkalis, organic solvents, and oils. In the petrochemical industry, the media transported or stored in various pipelines and reactors are often highly corrosive. Fluororubber O-rings can serve for extended periods in these harsh environments, effectively preventing leakage and ensuring production safety and continuity.

[0003] Currently, O-rings on the market are mainly composed of fluororubber substrate and auxiliary sealing reinforcement components. The simple structural design makes it difficult to adapt to complex sealing scenarios. Traditional circular cross-sections have a small contact area at low pressure, making them prone to point contact leakage due to microscopic unevenness of the sealing surface. At high pressure, due to the lack of a support structure, the probability of the sealing ring being squeezed into the sealing gap is high. Especially when the machining error of the sealing groove exceeds one millimeter, the risk of extrusion and tearing increases sharply. Long-term friction causes wear on the sealing ring lip, forming a leakage channel. At the same time, poor installation and operating condition adaptability further aggravate sealing failure. Traditional O-rings have no guiding structure, and the twist rate is high during manual installation. The compression deviation of the twisted part is large, which directly leads to insufficient local sealing pressure. For large-diameter sealing rings, it is difficult to ensure uniform compression in the circumferential direction during manual assembly. In the flange seal of a wind power equipment, the uneven distribution of bolt preload due to the eccentric installation of the O-ring caused local leakage on the sealing surface after six months of operation. In addition, traditional sealing rings are extremely sensitive to the parallelism error of the sealing surface. In the case of slight vibration of the pump body and valve, the relative displacement of the sealing surface will disrupt the stable contact of the sealing ring and form periodic leakage. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fluororubber O-ring, which aims to improve the poor sealing effect of traditional O-rings in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fluororubber O-ring, comprising an outer ring, wherein a sealing mechanism is provided on the inner wall of the outer ring for sealing, and a disassembly mechanism is provided on both the left and right sides of the inner wall of the outer ring for installing and disassembling the sealing ring.

At the same time, it allows for quick disassembly and carrying of sealing rings of different sizes, and can be quickly installed when needed. Attached Figure Description

[0038] Specifically, elastic component 205 is mainly composed of a fixed circular plate 2051. The position of this fixed circular plate 2051 is crucial.

[0041] Working principle: A flexible plate 301 slides on the inner wall of the outer ring 1. When the outer ring 1 is installed in a fixed position, during sealing, the top of the outer ring 1 will be subjected to pressure, which will cause the sliding shaft 2031 to drive the tapered sleeve 2032 to slide downward. At the same time, the tapered sleeve 2032 can contact the inner ring 201, which will cause the inner ring 201 to further contract inward, thereby achieving the function of strengthening the sealing effect. It is easy to operate while meeting the high-strength sealing effect.

[0042] Inner rings 201 are fixed on both the left and right sides of the outer ring 1 at the rear. Meanwhile, a fixing sleeve 3031 is fixed on the rear side of the inner wall of the outer ring 1 at the front. After the outer ring 1 is installed, the top is compressed, which allows the engaging shaft 3041, which is elastically supported by spring 3032, to engage in the inner wall of the engaging hole 3042. This enables the outer rings 1 at the front and rear sides to be quickly installed and fixed. It also allows for quick disassembly and transport of sealing rings of different sizes, and quick installation when needed.
