[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] As described in the background technology, after the spring of the existing spring energy storage sealing ring is compressed, the sealing ring cannot be restored to its original shape, resulting in a poor sealing effect. The sealing effect needs to be improved. For this reason, this embodiment provides a spring energy storage sealing ring with good sealing effect. The device can achieve the effect of efficient sealing and durable use of the sealing ring.

[0023] See also Figure 1-4 This embodiment proposes a spring energy storage sealing ring with good sealing effect, including a first sealing ring 1, and a second sealing ring 2 is fixedly connected to the bottom surface of the first sealing ring 1. The first sealing ring 1 and the second sealing ring 2 are both made of polytetrafluorocarbon fiber, which can increase the overall wear resistance and high temperature resistance of the first sealing ring 1 and the second sealing ring 2.

[0024] An O-shaped groove 14 is provided on the bottom surface of the second sealing ring 2, and an O-shaped spring 15 is clamped on the inner wall of the O-shaped groove 14. Two sealing lips 8 are fixedly connected to the bottom surface of the second sealing ring 2. The sealing lips 8 are made of rubber material, which can increase the elastic energy storage effect of the second sealing ring 2 and facilitate the sealing use of the second sealing ring 2. A V-shaped ring groove 9 is provided on the upper surface of the first sealing ring 1, and a V-shaped spring 10 is clamped on the inner wall of the V-shaped ring groove 9. A rubber ring 11 is provided inside the V-shaped spring 10.

[0025] The inner wall of the V-shaped ring groove 9 is fixedly connected with a rubber support disk 13, and the top ends of the two rubber support disks 13 are jointly clamped with a T-shaped sealing ring 3. The bottom end of the T-shaped sealing ring 3 is fixedly connected to the upper surface of the rubber ring 11. A circular clamping groove 6 is opened on the upper surface of the T-shaped sealing ring 3, and a circular sealing ring 4 is clamped on the inner wall of the circular clamping groove 6, which can achieve the sealing of the top of the first sealing ring 1 and increase the sealing effect of the first sealing ring 1. The inner wall of the rubber ring 11 is fixedly connected with a stainless steel elastic support ring 12 arranged in a ring.

[0026] The inner wall of the first sealing ring 1 and the inner wall of the second sealing ring 2 are fixedly connected with an inner lining sealing sleeve 5. The inner lining sealing sleeve 5 is made of rubber material and can protect the inner walls of the first sealing ring 1 and the second sealing ring 2. The upper surface of the first sealing ring 1 is provided with a model mark 7, and the model mark 7 is located in the middle of the left side of the first sealing ring 1, which is convenient for people to understand and use this spring energy storage sealing ring.

[0027] Working principle: When in use, the first sealing ring 1 and the second sealing ring 2 are nested in the groove that needs to be sealed. When the first sealing ring 1 and the second sealing ring 2 are squeezed and held by external force, the V-shaped spring 10 and the O-shaped spring 15 are compressed to form an outward tension, which prompts the first sealing ring 1 and the second sealing ring 2 to expand outward and fit tightly against the sealing groove, thereby achieving the sealing use of this spring energy storage sealing ring. At the same time, the rubber ring 11 and the stainless steel elastic support ring 12 are used to elastically protect the V-shaped spring 10, reduce the deformation of the V-shaped spring 10, achieve elastic support for the first sealing ring 1, and achieve effective sealing use of this spring energy storage sealing ring.
