Description

Technical Field

[0001] This utility model relates to the field of sealing gasket technology, and in particular to a sealing gasket that is not easily deformed. Background Technology

[0002] In modern industry, gaskets are used as key sealing components in many industries such as machinery manufacturing, petrochemicals, power energy, food and medicine. From pipe connections and pressure vessel sealing to the connection of mechanical equipment components, gaskets play an important role in preventing fluid leakage and ensuring the normal operation of equipment.

[0003] In mechanical equipment, gaskets can deform due to frequent vibration and mechanical stress. Once the gasket is deformed, gaps will appear on its originally tightly fitted sealing surface, leading to fluid leakage. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a sealing gasket that is not easily deformed.

[0005] The technical solution adopted by this utility model is: a non-deformable sealing gasket, including a base plate, on which protective layers are symmetrically arranged on the upper and lower sides. Two adjacent sides of the two protective layers are respectively fixedly connected with reinforcing rings. The two reinforcing rings are respectively inserted into the annular grooves opened on the upper and lower sides of the base plate. Each protective layer has multiple buffer holes arranged in a ring array on its surface. The surface of the base plate is fitted with reinforcing rings, and the two protective layers are located inside the reinforcing rings, effectively preventing the protective layers from deforming.

[0006] Preferably, both the protective layer and the reinforcing ring are fixedly connected to the base plate by a high-temperature resistant adhesive. The fixed connection between the protective layer and the reinforcing ring by the high-temperature resistant adhesive ensures a tight connection between the protective layer and the reinforcing ring, so as to work together to provide protection and reinforcement and effectively improve the overall performance of the sealing gasket.

[0007] Preferably, a block is fixedly connected to each of the two adjacent reinforcing rings, and the block is inserted into a square groove opened inside the base plate to ensure the structural stability of the sealing gasket under complex stress conditions.

[0008] Preferably, metal reinforcing wires are inserted into the equidistant annular holes inside the reinforcing ring, and the metal reinforcing wires are fixedly connected to the reinforcing ring, which effectively limits the deformation of the protective layer and enhances the overall structural strength and stability of the sealing gasket.

[0009] Preferably, each of the buffer holes is filled with an elastic buffer material, which is silicone rubber with added nano-silica particles. This effectively reduces the risk of gasket deformation, and its good elastic recovery performance ensures that the gasket quickly returns to its original shape after the pressure is removed, maintaining the sealing performance.

[0010] Preferably, the protective layer is made of polytetrafluoroethylene (PTFE) to prevent wear on the surface of the sealing gasket, extend its service life, and ensure the sealing effect.

[0011] Preferably, the circumferential surface of the protective layer is fixedly connected by a high-temperature resistant adhesive and a reinforcing ring to ensure the connection stability between the protective layer and the reinforcing ring and to prevent damage to the edge of the protective layer.

[0012] Preferably, a screw is inserted into the through hole on the surface of the reinforcing ring, and the screw is inserted into the threaded hole on the surface of the base plate. The screw and the base plate are threadedly connected, so that the reinforcing ring can continuously and stably provide constraint and protection to the protective layer, enhance the stability of the overall structure of the sealing gasket, and ensure the reliability of the sealing performance.

[0013] The beneficial effects of this utility model are: it helps to resist the influence of external pressure, temperature changes and media corrosion on the sealing gasket, effectively improves the deformation resistance of the sealing gasket, ensures the stability of its sealing performance, and thus achieves the effect of the sealing gasket being not easily deformed and providing a stable seal.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1 to 7 As shown, this embodiment provides a non-deformable sealing gasket, including a base plate 1. Protective layers 2 are symmetrically arranged on the upper and lower surfaces of the base plate 1. The protective layers 2 are made of polytetrafluoroethylene (PTFE) and can effectively resist corrosion from external media and temperature changes, providing a reliable protective barrier for the base plate 1. Reinforcing rings 5 ​​are fixedly connected to adjacent sides of the two protective layers 2. The reinforcing rings 5 ​​significantly improve the strength and rigidity of the connection between the protective layers 2 and the base plate 1. The two reinforcing rings 5 ​​are respectively inserted into annular grooves 4 opened on the upper and lower surfaces of the base plate 1. This interlocking structure enhances the connection stability between components. Qualitatively, the lateral displacement of the protective layer 2 is limited, improving the overall deformation resistance of the sealing gasket. Each protective layer 2 has multiple buffer holes 9 arranged in a ring array on its surface. When the sealing gasket is subjected to external pressure, the buffer holes 9 can guide the pressure to be evenly distributed, avoiding local stress concentration. The surface of the base plate 1 is fitted with a reinforcing ring 3, which can form an outer constraint on the protective layer 2, further enhancing the structural strength of the sealing gasket. The two protective layers 2 are located inside the reinforcing ring 3, ensuring that the protective layer 2 is within the protection range of the reinforcing ring 3, effectively preventing the protective layer 2 from deforming.

[0024] Both the protective layer 2 and the reinforcing ring 5 are fixedly connected to the base plate 1 by a high-temperature resistant adhesive. The high-temperature resistant adhesive can maintain good bonding strength in high-temperature environments, so that the protective layer 2, the reinforcing ring 5 and the base plate 1 are firmly bonded together, ensuring the structural stability of the gasket under high-temperature conditions. The fixed connection between the protective layer 2 and the reinforcing ring 5 by the high-temperature resistant adhesive ensures that the connection between the protective layer 2 and the reinforcing ring 5 is tight, and they work together to play a protective and reinforcing role, effectively improving the overall performance of the gasket.

[0025] Two reinforcing rings 5 ​​are fixedly connected to adjacent sides with blocks 7. The blocks 7 are inserted into the square grooves 6 opened inside the base plate 1. This matching structure of blocks 7 and square grooves 6 not only restricts the rotation of the protective layer 2 on the surface of the base plate 1, but also provides effective torque transmission and resistance when the sealing gasket is subjected to torque force, further enhancing the firmness of the connection between the protective layer 2 and the base plate 1, and ensuring the structural stability of the sealing gasket under complex stress conditions.

[0026] Metal reinforcing wires 11 are inserted into the annular holes 12 that are equidistantly opened inside the reinforcing ring 3. The metal reinforcing wires 11 and the reinforcing ring 3 are fixedly connected. Due to their high strength characteristics, the metal reinforcing wires 11 significantly improve the tensile and compressive strength of the reinforcing ring 3, making it less prone to deformation when the reinforcing ring 3 provides constraint on the protective layer 2. This more effectively limits the deformation of the protective layer 2 and enhances the overall structural strength and stability of the sealing gasket.

[0027] Each buffer hole 9 is filled with an elastic buffer material 8, which is silicone rubber with added nano-silica particles. The nano-silica particles enhance the elastic modulus and strength of the silicone rubber. When the gasket is subjected to pressure, the elastic buffer material 8 can undergo elastic deformation, efficiently absorbing and buffering pressure energy, reducing the damage of pressure to the gasket structure, and effectively reducing the risk of gasket deformation. At the same time, its good elastic recovery performance ensures that the gasket quickly returns to its original shape after the pressure is removed, maintaining the sealing performance.

[0028] The protective layer 2 is made of polytetrafluoroethylene (PTFE), which has an extremely low coefficient of friction, excellent chemical stability, and resistance to high and low temperatures. It can effectively reduce the friction between external substances and the surface of the gasket, prevent wear on the gasket surface, extend service life, and ensure sealing effect.

[0029] The circumferential surface of the protective layer 2 is fixedly connected to the reinforcing ring 3 by a high-temperature resistant adhesive. This connection method allows the protective layer 2 and the reinforcing ring 3 to be tightly bonded together. The reinforcing ring 3 can evenly transmit the restraining force to the protective layer 2 through the bonding part, further enhancing the deformation resistance of the protective layer 2. At the same time, during the installation and removal of the sealing gasket, the connection stability between the protective layer 2 and the reinforcing ring 3 is ensured, and the edge of the protective layer 2 is prevented from being damaged.

[0030] A screw 14 is inserted into the through hole 10 on the surface of the reinforcing ring 3. The screw 14 is inserted into the threaded hole 13 on the surface of the base plate 1. The screw 14 and the base plate 1 are threadedly connected. The tightening effect of the screw 14 ensures that the relative position between the reinforcing ring 3 and the base plate 1 is fixed, preventing the reinforcing ring 3 from rotating or moving axially on the surface of the base plate 1. This allows the reinforcing ring 3 to continuously and stably provide constraint and protection for the protective layer 2, enhances the overall stability of the sealing gasket, and ensures the reliability of the sealing performance.

[0031] Working principle: The base plate 1 serves as the basic load-bearing component of the sealing gasket, providing shape support and basic sealing surface for the entire sealing gasket. The protective layer 2 is made of polytetrafluoroethylene (PTFE) material and covers the upper and lower surfaces of the base plate 1. With the excellent corrosion resistance, high and low temperature resistance and non-stick properties of PTFE, it effectively resists the corrosion of external media and the influence of temperature changes on the sealing gasket, protects the base plate 1 from external environmental damage, and maintains the stable performance of the sealing gasket.

[0032] The reinforcing ring 5 is fixedly connected to the protective layer 2 and the base plate 1 respectively by a high-temperature resistant adhesive, and is inserted into the annular grooves 4 opened on the upper and lower sides of the base plate 1. At the same time, the square block 7 on its adjacent side is inserted into the square groove 6 opened inside the base plate 1. This design enhances the connection strength between the protective layer 2 and the base plate 1, making the protective layer 2 and the base plate 1 tightly integrated into a whole. On the other hand, the cooperation between the square block 7 and the square groove 6 effectively restricts the rotation of the protective layer 2 on the surface of the base plate 1, ensuring that the protective layer 2 will not be displaced or shifted during operation, thereby maintaining the stability of the sealing gasket structure and improving its resistance to deformation.

[0033] The reinforcing ring 3 further strengthens and protects the protective layer 2, preventing the protective layer 2 from deforming under external pressure or other external forces. The metal reinforcing wire 11 enhances the strength and rigidity of the reinforcing ring 3 itself, ensuring the wrapping effect of the reinforcing ring 3 on the protective layer 2, making the reinforcing ring 3 more reliable in protecting the protective layer 2. The screw 14 prevents the reinforcing ring 3 from rotating on the surface of the base plate 1, ensuring that the relative positions between the reinforcing ring 3, the protective layer 2 and the base plate 1 are fixed, making the entire sealing gasket structure more stable.

[0034] In practical use, when the gasket is installed between components that need to be sealed and is subjected to pressure, the elastic buffer material 8 filled in the multiple annular array of buffer holes 9 on the surface of the protective layer 2 plays a role. The elastic buffer material 8 is made of silicone rubber with added nano silica particles. The nano silica particles enhance the strength and elastic modulus of the silicone rubber. When subjected to pressure, the elastic silicone rubber undergoes elastic deformation, absorbing and buffering the pressure, reducing the damage of the pressure to the overall structure of the gasket, and reducing the possibility of gasket deformation. At the same time, the multiple buffer holes 9 are distributed in an annular array, which can evenly distribute the pressure and avoid excessive local pressure that could cause the gasket to deform.

[0035] Throughout the entire process, the base plate 1, protective layer 2, reinforcing ring 5, strengthening ring 3, metal reinforcing wire 11, screw 14, and elastic buffer material 8 work together to resist the influence of external pressure, temperature changes, and media corrosion on the sealing gasket, effectively improving the deformation resistance of the sealing gasket and ensuring the stability of its sealing performance, thereby achieving the effect of the sealing gasket being not easily deformed and providing a stable seal.
