Technical Field

[0001] The utility model relates to the technical field of sealing, in particular to a nozzle sealing ring that is convenient for maintenance and efficient. Background Technique

[0002] A sealing ring is a key component widely used in various mechanical equipment and systems. Its main function is to prevent the leakage of fluids (including liquids and gases) or solid particles from adjacent mating surfaces, and to prevent external impurities such as dust and moisture from invading the interior of the machinery and equipment. The material, design, and manufacturing quality of the sealing ring directly affect the working performance, service life, and safety of the equipment. Common sealing ring materials include rubber, silicone rubber, metal rubber, etc. These materials have different physical and chemical properties and are suitable for different working environments and media.

[0003] At present, most sealing rings optimize the structure of the sealing ring, such as adopting a multi-layer lip design and a specific groove shape to reduce wear and enhance the sealing effect. At the same time, a rubber material with heat resistance, pressure resistance, and corrosion resistance is selected to ensure that the sealing ring can maintain stable performance in different working environments. This design not only improves the reliability of the sealing ring but also simplifies the maintenance process, making it more convenient for maintenance and upkeep, thereby improving the overall working efficiency.
