Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, and in particular to a non-standard double-layer sealing ring. Background Technology

[0002] A sealing ring is a ring composed of one or more parts. Different types of sealing rings have different media resistance, hardness, and application range. The selection of a sealing ring depends on the requirements of the product application. Sealing rings are generally used in many fields such as automobiles, construction machinery, aerospace equipment, and plastic machinery. Irregularly shaped sealing rings are a general term for rubber or fabric-reinforced sealing rings with cross-sections other than circular and rectangular, such as Y-shaped, V-shaped, U-shaped, X-shaped, D-shaped, triangular, and T-shaped sealing rings. Currently, most sealing rings are single-ring designs, which are easily damaged, have a short service life, require regular maintenance and replacement, and are not very secure during sealing.

[0003] Chinese patent website discloses a non-standard double-layer sealing ring with the reference number "CN220956773U". It consists of an upper and lower sealing ring integrally formed, with reinforcing pieces at the top and bottom of both the upper and lower sealing rings. A recessed portion is provided at the connection between the upper and lower sealing rings. This invention achieves a double-layer seal through the upper and lower sealing rings, effectively increasing the sealing effect. The reinforcing ring extends outwards, further enhancing the sealing performance. Finally, the metal piece prevents the reinforcing ring from easily returning to its original shape after extension, maintaining the stability of the sealing ring during use. However, it is prone to loosening during use. Utility Model Content

Through the cooperation of the ring assembly, the first groove, the first upper sealing ring, the first lower sealing ring, the second groove, the second upper sealing ring, the second lower sealing ring, the inner protrusion, and the elastic ring, the inner protrusion is evenly arranged. This increases the frictional force when the sealing body is in contact with the sealing body, making it more stable during use and less prone to loosening, thus improving the sealing effect. By setting up inner and outer double-layer sealing rings for sealing operations, it can still be used even if one is damaged. The elastic ring increases the clamping force, improving the sealing effect.

[0006] According to the present invention, a non-standard double-layer sealing ring is provided with a sealing gasket on the upper surface of the mounting ring and a sealing gasket on the lower surface of the mounting ring. These components ensure that the sealing gasket fits tightly against the sealing body, improving the sealing effect and preventing leakage.

[0007] According to the present invention, a non-circular double-layer sealing ring has inner protrusions that are evenly distributed around its circumference and are semi-annular. These components facilitate increased friction and prevent loosening.

[0008] According to the present invention, a non-circular double-layer sealing ring has an anti-corrosion layer coated on the outer surfaces of the first upper sealing ring and the first lower sealing ring, and a waterproof layer coated on the inner surfaces of the second upper sealing ring and the second lower sealing ring. These components effectively prevent corrosion that could reduce the sealing performance.

[0009] According to the present invention, a non-standard double-layer sealing ring is provided, wherein the sealing gasket, the second upper sealing ring, the second lower sealing ring, and the mounting ring are all made of rubber. These components facilitate the sealing operation of the sealing body.

[0010] According to the present invention, a non-standard double-layer sealing ring is provided, wherein the first upper sealing ring and the first lower sealing ring are integrally formed, and the elastic ring is located at the connection point. These components facilitate the tightening of the elastic ring, thereby improving the sealing effect.

[0011] According to the present invention, a non-circular double-layer sealing ring is provided in the second groove, and the protective pad is movably connected to the second upper sealing ring and the second lower sealing ring. These components prevent wear and protect the second upper and second lower sealing rings.
