Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing ring, specifically, a kind of anti-corrosion sealing ring. BACKGROUND

[0002] Sealing ring is a ring-shaped mechanical element made of elastic material, and the common materials include rubber, plastic, etc. Its main function is to provide effective sealing effect. When installed between two or more components, the sealing ring tightly adheres to the sealing surface through its elastic deformation, preventing fluid or gas leakage at the connection, ensuring the sealing of the system. It can work in various environments, such as preventing lubricating oil leakage in mechanical equipment, preventing liquid or gas leakage in pipeline systems, etc. At the same time, the sealing ring can also play a certain waterproof and dustproof role, protecting the internal components from external impurities. In addition, in some specific applications, the sealing ring may also have auxiliary functions such as shock absorption, fixation and positioning of components, providing important protection for stable operation and efficient work of the equipment.

[0003] Sealing rings are diverse in type and can be divided into O-shaped sealing rings, X-shaped sealing rings, V-shaped sealing rings, Y-shaped sealing rings, L-shaped sealing rings, U-shaped sealing rings, and star-shaped sealing rings, etc. In actual application, Y-shaped sealing rings and O-shaped sealing rings can be used in combination to form a composite sealing ring. However, this composite sealing ring has some problems when used. Specifically, the O-shaped sealing ring is assembled in the notch of the Y-shaped sealing ring, and is only clamped and positioned by the elastic action of the Y-shaped sealing ring. This positioning method makes the stability of the composite sealing ring lower, and in some working environments, it may easily shift, loosen, etc., affecting the sealing effect.
