Description

Technical Field

[0001] The present application relates to the technical field of sealing accessories, and in particular to a high-pressure resistant elastic sealing ring. Background Art

[0002] In the field of high-pressure sealing, elastic sealing rings are widely used due to their excellent elasticity and sealing performance. However, as sealing requirements continue to increase, traditional elastic sealing rings may fail due to excessive pressure in high-pressure environments, causing gas or liquid leakage, seriously affecting the safety and stability of the sealing system. Therefore, how to improve the sealing performance of elastic sealing rings in high-pressure environments has become a pressing technical problem.

[0003] Currently, a common approach to addressing these technical issues is to optimize the structural design of elastic sealing rings to improve their high-pressure resistance. For example, reinforcing ribs are installed within the elastic sealing ring to enhance its structural strength. However, while this approach can improve the elastic sealing ring's high-pressure resistance to a certain extent, it also increases its manufacturing complexity and cost, and offers limited improvement in sealing performance under high-pressure environments.

[0004] Existing elastic sealing rings still suffer from unstable sealing performance and leakage in high-pressure environments. While traditional optimization methods can provide some improvement, they do not fundamentally address the sealing performance issues in high-pressure environments. Therefore, how to effectively improve the sealing performance of elastic sealing rings in high-pressure environments without increasing manufacturing complexity and cost has become a technical challenge urgently needed to be addressed by those skilled in the art. Utility Model Content

[0005] In order to reduce leakage, deformation and damage of the elastic sealing ring under high-pressure environment, the present application provides a high-pressure resistant elastic sealing ring.

[0006] The present application provides a high-pressure resistant elastic sealing ring, which adopts the following technical solution:

[0007] A high-pressure resistant elastic sealing ring includes an elastic sealing ring body, which is annular. Both ends of the elastic sealing ring body along the axial direction are provided with placement grooves, the open ends of the placement grooves are both facing outward, and the placement grooves are all circumferentially arranged. A pressure-resistant support member is provided in the placement groove for making the outer wall of the elastic sealing ring body close to the sealing side. Both ends of the elastic sealing ring body are provided with blocking steps for preventing the pressure-resistant support member from falling off. When the pressure-resistant support member is located in the placement groove, the pressure-resistant support member abuts against the blocking step.

[0008] By adopting the above technical solution, the elastic sealing ring body is ring-shaped, which is convenient for installation and positioning; the placement groove opened on the sealing ring provides a stable installation space for the pressure-resistant support part; the setting of the blocking step enables the pressure-resistant support part to be accurately positioned during installation and prevents the pressure-resistant support part from falling out of the placement groove, providing a structurally stable elastic sealing ring that can effectively adapt to different pressure environments through the pressure-resistant support part and maintain a good sealing effect.

[0009] Optionally, the pressure-resistant support member is a leaf spring, which is tightly attached to the inner wall of the placement groove, and the cross-section of the leaf spring is V-shaped.

[0010] By adopting the above technical solution, the V-section leaf spring can provide better elastic force, so that the elastic sealing ring body fits more closely to the sealing side under high pressure environment, thereby enhancing the sealing effect.

[0011] Optionally, a baffle is provided on one side of the elastic sealing ring body, and the baffle is arranged on the side of the elastic sealing ring body close to the high-pressure environment.

[0012] By adopting the above technical solution, under high pressure conditions, the pressure will cause the spring shrapnel to deform excessively. By setting up a baffle, the internal structure can be protected, thereby preventing direct impact of the medium under high pressure environment, thereby improving the life of the structure.

[0013] Optionally, a snap ring is fixedly connected to one side of the baffle close to the leaf spring to facilitate installation of the baffle. The snap ring is circumferentially arranged and abuts against the blocking step.

[0014] By adopting the above technical solution, the baffle can be easily installed and removed through the mutual cooperation of the clamping ring and the blocking step, while ensuring the stability of the baffle during use.

[0015] Optionally, the elastic sealing ring body is made of a high-pressure resistant elastic material to ensure sealing performance and service life in a high-pressure environment.

[0016] By adopting the above technical solution and using high-pressure resistant elastic materials, the material of the elastic sealing ring body has excellent high-pressure resistance and elastic recovery ability, and can maintain a stable sealing effect under extreme high-pressure environments.

[0017] Optionally, the pressure-resistant support member is an O-ring, and the O-ring is tightly attached to the inner wall of the placement groove.

[0018] By adopting the above technical solution, the O-ring, as a common sealing element, has good elasticity and sealing performance, can simplify the structure and reduce costs.

[0019] Optionally, an outer conical surface is provided on the outer circumference of the elastic sealing ring body at a position corresponding to the placement groove, and the outer conical surface is inclined from the inside to the outside. An inner conical surface is provided on the inner circumference of the elastic sealing ring body at a position corresponding to the placement groove, and the inner conical surface is inclined from the inside to the outside.

[0020] By adopting the above technical solution, the conical surface design increases the wall thickness of the elastic sealing ring at the corresponding placement groove, reducing the risk of deformation and damage to the sealing ring under high pressure, extending the service life of the sealing ring. At the same time, it also improves the sealing performance of the sealing ring and prevents leakage during operation.

[0021] Optionally, chamfers are provided at the connection positions between the outer conical surface and the inner conical surface and the end surface of the elastic sealing ring body.

[0022] By adopting the above technical solution, the chamfered angle reduces the friction during the installation process, making the installation of the sealing ring faster and smoother.

[0023] In summary, the present application includes at least one of the following beneficial technical effects of a high-pressure resistant elastic sealing ring:

[0024] 1. By adopting the combined structure of the placement groove and the support member, the elastic sealing ring can be closely attached to the sealing side under high pressure environment through the elastic force of the support member, thereby maintaining a good sealing effect;

[0025] 2. By setting up structures such as baffles and clamping rings, the protection performance of the sealing ring is improved, the installation and disassembly operations are facilitated, and the convenience of use is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses a high-pressure resistant elastic sealing ring.

[0033] Reference Figure 1 and Figure 2 A high-pressure-resistant elastic sealing ring includes an elastic sealing ring body 1 and a pressure-resistant support member 2. The elastic sealing ring body 1 has placement grooves 11 at both ends along the axial direction. The opening ends of the placement grooves 11 face outward, the placement grooves 11 are arranged circumferentially, and the pressure-resistant support member 2 is located within the placement grooves 11. The elastic sealing ring body 1 is used to seal the sealing side, and the pressure-resistant support member 2 is closely attached to the placement grooves 11, increasing the elasticity of the sealing ring, improving the support strength, adapting to high-pressure environments, and improving sealing performance.

[0034] Reference Figure 1 and Figure 2 The elastic sealing ring body 1 is annular, and both ends of the elastic sealing ring body 1 are provided with blocking steps 12 for preventing the pressure-resistant support member 2 from falling off. When the pressure-resistant support member 2 is located in the placement groove 11, the pressure-resistant support member 2 abuts against the blocking steps 12. The elastic sealing ring body 1 is annular, which is convenient for installation and positioning; the provision of the blocking steps 12 enables the pressure-resistant support member 2 to be accurately positioned during installation and prevents the pressure-resistant support member 2 from falling out of the placement groove 11, providing a structurally stable elastic sealing ring that can effectively adapt to different pressure environments through the pressure-resistant support member 2 and maintain a good sealing effect.

[0035] Reference Figure 2 An outer conical surface 13 is provided on the outer circumferential surface of the elastic sealing ring body 1 at a position corresponding to the placement groove 11, and the outer conical surface 13 is inclined from the inside to the outside; an inner conical surface 14 is provided on the inner circumferential surface of the elastic sealing ring body 1 at a position corresponding to the placement groove 11, and the inner conical surface 14 is inclined from the inside to the outside, and chamfers 15 are provided at the connection positions of the outer conical surface 13 and the inner conical surface 14 with the end face of the elastic sealing ring body 1.

[0036] Reference Figure 2 The tapered design increases the wall thickness of the elastic sealing ring at the location corresponding to the placement groove 11, reducing the risk of deformation and damage to the sealing ring under high pressure and extending the service life of the sealing ring. At the same time, it also improves the sealing performance of the sealing ring and prevents leakage during operation. The setting of the chamfer 15 reduces friction during installation, making the installation of the sealing ring faster and smoother.

[0037] Reference Figure 1The elastic sealing ring body 1 is made of a high-pressure resistant elastic material to ensure sealing performance and service life in high-pressure environments. The high-pressure resistant material is fluororubber. By using fluororubber, the elastic sealing ring body 1 has excellent high-pressure resistance and elastic recovery ability, and can maintain a stable sealing effect in extreme high-pressure environments.

[0038] Reference Figure 1 and Figure 3 The pressure-resistant support member 2 includes a leaf spring 21 and a baffle 22. The leaf spring 21 is tightly attached to the inner wall of the placement groove 11. The cross-section of the leaf spring 21 is V-shaped. The baffle 22 is located on one side of the elastic sealing ring body 1. The baffle 22 is arranged on the side of the elastic sealing ring body 1 close to the high-pressure environment. The side of the baffle 22 close to the leaf spring 21 is fixedly connected with a snap ring 23 for facilitating the installation of the baffle 22. The snap ring 23 is circumferentially arranged and abuts against the blocking step 12.

[0039] Reference Figure 1 and Figure 3 The V-shaped cross-section leaf spring 21 can provide better elastic force, so that the elastic sealing ring body 1 fits more closely to the sealing side under high pressure environment, thereby enhancing the sealing effect; under high pressure, the pressure will cause the spring leaf to deform excessively. By setting the baffle 22, it can protect the internal structure, thereby preventing the direct impact of the medium under high pressure environment, thereby improving the life of the structure. Through the mutual cooperation of the clamping ring 23 and the blocking step 12, the baffle 22 can be easily installed and removed, while ensuring the stability of the baffle 22 during use.

[0040] Reference Figure 4 In another embodiment of the application, the support member is an O-ring 24, which is tightly attached to the inner wall of the placement groove 11. As a common sealing element, the O-ring 24 has good elasticity and sealing performance, can simplify the structure and reduce costs, and can adapt to changes in high-pressure environments, ensuring the reliability and durability of the sealing ring.

[0041] The implementation principle of a high-pressure resistant elastic sealing ring in the embodiment of the present application is as follows: first, a V-shaped spring is clamped into the placement groove 11, and then the baffle 22 is clamped into the blocking step 12. When dynamic sealing is required in a high-pressure working environment, the baffle ring can effectively place high-pressure gas into the placement groove 11, thereby preventing the V-shaped spring from being deformed and damaged under the impact of the high-pressure gas. At this time, the elastic sealing ring is sleeved on the rotating shaft of the motor, and the end with the placement groove 11 is placed close to the motor. The V-shaped spring is in the placement cavity, and the specific bending angle of the spring is used to apply a radial force to the outer circumference and inner circumference of the elastic sealing ring to move away from each other, thereby increasing the pressure at the sealing position where the elastic sealing ring abuts, and enhancing the overall sealing performance.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
