Background
The sealing ring is a part with sealing performance in a certain temperature range under working pressure, and has good stability and good waterproof, oil-proof and antifouling effects, so that the sealing ring is widely applied to production and life.
For the sealing of some precision parts, such as the sealing of complex moving parts such as double piston rods of oil cylinders, etc., a sealing ring is generally clung to the surface of a sealing element to block a leakage channel to obtain a sealing effect, and self-tightening sealing is realized through the pressure of a medium. However, the sealing mode has the disadvantage that the sealing ring is easily damaged irreversibly by high pressure during working, so that the sealing ring is deformed and damaged, the service life of the sealing ring is generally not long, and the sealing ring needs to be replaced periodically to ensure the whole sealing effect. On the other hand, in practical application, in order to ensure the sealing effect, multiple sealing is often performed by adopting a plurality of sealing rings or a mode of overlapping the sealing rings and the sealing gasket, and the installation is inconvenient.

The utility model aims to provide a double seal ring with good sealing performance, which comprises an integrally formed seal ring body, wherein one end of the seal ring body is provided with an outer seal lip, and the other end of the seal ring body is provided with an inner seal lip; an outer lip bulge is arranged on the upper end face of the outer sealing lip, and a groove is formed in the bottom end of the outer sealing lip; an inner lip bulge is arranged on the upper end face of the inner sealing lip.
In order to make the installation of the seal ring smoother, preferably, an outer lip chamfer is provided at a joint of the outer seal lip and the seal ring body.
In order to make the installation of the seal ring smoother, preferably, an inner lip chamfer is arranged at the joint of the inner seal lip and the seal ring body.
In order to enhance the pressure resistance of the sealing ring, preferably, the inner sealing lip and the inner lip bulge are both in annular frustum structures.
In order to make the installation of the sealing ring smoother and enhance the sealing performance, it is preferable that the outer lip chamfer and the inner lip chamfer are both arc-shaped structures.
Advantageous effects
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) the structure of the utility model is arranged to achieve the double sealing effect of sealing the inner ring and the outer ring simultaneously by using one sealing ring, which is economical and practical;
(2) the inner sealing lip of the utility model adopts a frustum structure, the stress area of the sealing ring is larger, the compression resistance of the sealing ring can be enhanced, the damage of the sealing pressure to the sealing ring is slowed down, and the service life of the sealing ring is prolonged;
(3) the utility model discloses the setting can fix a position the sealing washer fast in the installation at the arch of outer seal lip and the frustum protruding structure of interior seal lip, and simple to operate is swift.
