Description

Technical Field

[0001] The utility model belongs to the technical field of sealing rings, in particular to a spring sealing ring. Background Art

[0002] The sealing ring is installed in the groove, and the spring is compressed to form an outward tension, which makes the sealing lip close to the sealing groove. Since the spring permanently provides elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the matching parts, thereby forming a seal from vacuum to low pressure. In addition, the system pressure will assist the spring in storing energy. The greater the pressure, the more fully the sealing lip fits the groove, thus forming a high-pressure seal.

[0003] The existing spring sealing rings still have some defects. Most of them are not stable enough and do not have the function of limiting the spring. The spring is directly stuck in the inside of the sealing ring and may pop out automatically due to the elastic force, which is inconvenient to use. For this reason, we propose a spring sealing ring.
