Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and fig. 2, the spring energy storage sealing ring includes a metal spring 1 and a sealing body 2, both of which are annular, in this embodiment, the metal spring 1 is an existing O-shaped metal spring, and the metal spring 1 may also be an existing U-shaped metal spring during actual manufacturing. The outer wall of the sealing body 2 is provided with a circle of annular groove, the metal spring 1 is clamped in the annular groove, two end faces of the sealing body 2 are provided with two circles of first convex rings 3 positioned on two sides of the metal spring 1, and the inner wall of the sealing body 2 is provided with two circles of second convex rings 4 protruding outwards in the radial direction.

This spring energy storage sealing washer passes through the setting of bulge loop one 3, make sealing body 2 little in the area of contact of the both ends face of metal spring 1 both sides, the roughness requirement to the sealing contact face has been reduced, bulge loop one 3 can form many rings of sealings under metal spring 1's elastic action and pressure auto-tightening action, it is sealed effectual, and bulge loop two 4 has also reduced the roughness requirement of sealing body 2 inner wall to sealed face, bulge loop two 4 can form multichannel radial effective seal under pressure auto-tightening action, sealing effect is further improved, therefore in the assembling process, even tiny wearing and tearing appear in sealing body 2 both ends face and inner wall, can not lead to sealed inefficacy yet, when this spring energy storage sealing washer is applied to the valve, the leakproofness of valve leak department just can be guaranteed to single quantity, and convenient for assembly, use cost is reduced.

In more detail, two end faces of the sealing body 2 close to the inner wall are respectively provided with a circle of convex rings III 5, and the sealing performance of the two end faces of the sealing body 2 is further improved by the convex rings III 5; the two end faces of the sealing body 2 are provided with a plurality of first connecting ribs 6 which are circumferentially and uniformly distributed and are positioned between the first convex ring 3 and the third convex ring 5, the inner wall of the first connecting rib 6 is connected with the outer wall of the third convex ring 5 into a whole, the two ends of the sealing body 2 are provided with a plurality of second connecting ribs 7 which are circumferentially and uniformly distributed and are positioned between the third convex ring 5 and the inner wall of the sealing body 2, the outer wall of the second connecting rib 7 is connected with the inner wall of the third convex ring 5 into a whole, the inner wall of the second connecting rib 7 is flushed on the inner wall of the sealing body 2, when viewed from a radial cross section, the original two end faces of the sealing body 2 are two conical surfaces, the width of the inner wall of the sealing body 2 is smaller than that of the outer wall of the sealing body 2, the first connecting rib 6 and the second connecting rib 7 ensure the.

The first connecting ribs 6 and the second connecting ribs 7 are sixteen in the same number, and the middle positions of the two adjacent first connecting ribs 6 are provided with the second connecting rib 7 located on the other side of the third convex ring 5, so that the first connecting ribs 6 and the second connecting ribs 7 are reasonable in distribution, the supporting effect on the third convex ring 5 is good, the structural strength of the third convex ring 5 is good, and the sealing performance is good.

The first convex ring 3, the second convex ring 4 and the third convex ring 5 are all arc-shaped bulges, so that the first convex ring 3, the second convex ring 4 and the third convex ring 5 form approximate line contact, the requirement on the flatness of a sealing surface is not high, and the sealing effect is good; the steel ring 8 which is annular is coated in the sealing body 2, the steel ring 8 increases the structural strength of the sealing body 2, the bearing capacity is good, and the sealing effect under the high-pressure working condition is good.
