[0001] The utility model relates to the technical field of sealing rings, in particular to a flexible high-pressure sealing ring. Background Art

[0002] Usually, when preventing liquid leakage, a sealing ring is often used for sealing, while protecting mechanical parts from pollution and corrosion, being able to withstand the pressure of internal fluid, preventing leakage, and effectively isolating the external environment to avoid the intrusion of dust and moisture. Therefore, preventing the offset of the sealing ring and improving the sealing effect are also important.

[0003] In some existing devices, the sealing ring is prone to offset during high-pressure operation, resulting in sealing failure. Due to the elastic and compressive characteristics of the sealing ring material, it is difficult to effectively maintain its original shape under high pressure, thus affecting the sealing effect. For this reason, a flexible high-pressure sealing ring is proposed to solve the above problems. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0025] Referring to Figures 1 to 2 , an embodiment provided by the present utility model: a flexible high-pressure sealing ring, including a ring body 1. A splicing assembly for splicing and combination is provided on the outside of the ring body 1. The splicing assembly includes an anti-slip layer 6. An annular groove 2 is provided on the outside of the ring body 1. The design of the annular groove 2 is used to promote the good fit between the sealing ring and the device and enhance the sealing effect. A plurality of square grooves 3 are provided inside the ring body 1. The design of the square grooves 3 aims to increase the stress-bearing area inside the sealing ring, disperse the internal and external pressures, and prevent local stress concentration in a high-pressure environment. An anti-slip layer 6 is fixedly connected to the outside of the ring body 1. The design of the anti-slip layer 6 is used to increase the friction between the ring body 1 and the contact surface and prevent the sealing ring from slipping during operation. The outside of the anti-slip layer 6 is fixedly connected to the front side of the outside of the ring body 1. An external washer 9 is fixedly connected to the rear side of the outside of the ring body 1. The external washer 9 is fixed to the rear side of the ring body 1, aiming to provide additional sealing and reduce the leakage risk between the joint surfaces. A fixing groove 5 is provided inside the ring body 1. Among them, the device fitting surface can be fixed through the internal fixing groove 5 to prevent deviation. A plurality of through holes 4 are provided on the outside of the ring body 1, which can fix the device and prevent displacement during assembly or operation;

[0026] Referring to Figures 3 to 4 , a heat-resistant layer 7 is fixedly connected to the inside of the ring body 1. The main function of the heat-resistant layer 7 is to protect the internal structure of the ring body 1 from the influence of high-temperature environments and ensure the integrity and sealing performance of the material under overheating conditions. An extension ring 8 is fixedly connected to the outside of the heat-resistant layer 7. The extension ring 8 is combined with the heat-resistant layer 7 to enhance the sealing performance and improve the installation flexibility. The outside of the through hole 4 penetrates through the inside of the ring body 1. The through hole 4 can help relieve the fluctuation of the internal and external pressures and enable the sealing ring to maintain a stable sealing effect in a moving state. The outside of the fixing groove 5 is adjacent to the outside of a plurality of through holes 4. The outside of the extension ring 8 is fixedly connected to the front side of the outside of the heat-resistant layer 7. The outside of the extension ring 8 is on the inner wall of the ring body 1.

[0027] Working principle: First, the ring body 1 is accurately placed in the device connection area to be sealed. To ensure a good fit between the sealing ring and the device, the annular groove 2 outside the ring body 1 is designed to help it dock accurately and enhance the sealing effect at the same time. Then, the presence of the square groove 3 enables the internal structure to effectively increase the force-bearing area, thereby effectively dispersing the internal and external pressures and avoiding local stress concentration under high-pressure operations. During the assembly process, the anti-slip layer 6 is designed to enhance the friction between the ring body 1 and the contact surface to prevent the sealing ring from slipping during operation and ensure its stable position. At the same time, the external washer 9 fixedly connected to the rear side of the outside of the ring body 1 provides an additional sealing barrier, further reducing the leakage risk between the joint surfaces. The inside of the ring body 1 is designed with a fixing groove 5, which can ensure that the mating surface of the device is firm and prevent displacement caused by external forces. A plurality of through holes 4 are opened on the outside of the ring body 1 to firmly fix the sealing ring on the device and effectively prevent displacement during assembly or operation. Generally speaking, through the above structures and designs, the flexible high-pressure sealing ring plays an important sealing role in a high-pressure environment, ensuring the safety and efficiency of the device;

[0028] The combination of the installed heat-resistant layer 7 and the extension ring 8 improves the overall sealing performance and enhances the installation flexibility, enabling the sealing ring to adapt to the small displacements caused by temperature and pressure changes. On the inner wall of the sealing ring, the extension ring 8 ensures good contact with the heat-resistant layer 7, further increasing the sealing effect. In the design of the ring body 1, the fixing groove 5 prevents the sealing ring from shifting due to external forces by providing a stable fixing point. To sum up, through the interaction of each component, the device maintains reliable sealing in high-temperature and high-pressure working environments, ensuring the safe and efficient operation of the device.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
