Description

Technical Field

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

[0002] Sealing rings are widely used in industrial equipment and machinery. High-strength self-lubricating sealing rings are a special type of sealing element to prevent fluid leakage and contamination. With their self-lubricating and high-strength characteristics, they are widely used in various industrial and mechanical equipment. They can effectively prevent leakage, reduce friction, and extend the service life of equipment.

[0003] In the existing technology, some sealing rings cannot achieve good sealing and reduce wear at the same time. In high pressure, high temperature or corrosive environments, the risk of sealing failure is high. The sealing rings are prone to wear during use, which increases the frequency and cost of equipment maintenance. Therefore, high-strength self-lubricating sealing rings are proposed to solve the above problems. Utility Model Content

[0004] The high-strength self-lubricating sealing ring proposed in the utility model aims to improve the problem that some devices in the prior art cannot achieve better sealing and lubricating effects.

[0006] A high-strength self-lubricating sealing ring comprises a ring body, a friction block is fixedly connected to the outside of the ring body, and an oil outlet hole is opened on the outside of the ring body.

[0007] As a further description of the above technical solution:

[0008] A reinforcement ring is fixedly connected to the interior of the ring body, and an oil-soaked sponge is fixedly connected to the interior of the ring body.

[0009] As a further description of the above technical solution:

[0010] The outside of the ring body is fixedly connected with a reinforcement layer, and the outside of the ring body is fixedly connected with an anti-corrosion layer.

[0011] As a further description of the above technical solution:

[0012] The outer portion of the reinforcement layer is fixedly connected to the inner portion of the anti-corrosion layer.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, a friction block is installed on the outside of the sealing ring body to increase the contact area between the sealing ring and the object, increase the friction coefficient and enhance the sealing effect. A reinforcement ring is installed on the lower part of the interior. The reinforcement ring can improve the overall strength and pressure resistance of the sealing ring, so that it can still maintain a good sealing state in a high-pressure or intense exercise environment. An oil-immersed sponge is installed on the upper part of the interior, and multiple oil outlet holes are opened on the top. The oil-immersed sponge can continuously release lubricating oil through the oil outlet holes to ensure that the sealing ring always remains in a good lubricated state and reduce friction and wear.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4The present invention provides an embodiment of a high-strength self-lubricating sealing ring, comprising a ring body 1 made of polytetrafluoroethylene (PTFE), which exhibits excellent corrosion resistance and high-temperature resistance, as well as a low coefficient of friction and self-lubricating properties. A friction block 2 is fixedly connected to the outside of the ring body 1. Polytetrafluoroethylene (PTFE) has an extremely low coefficient of friction, is corrosion-resistant, high-temperature-resistant, and exhibits excellent self-lubricating properties. Oil outlet holes 3 are provided on the outside of the ring body 1 for supplying lubricating oil to the interior of the sealing ring. The design of these holes ensures a continuous supply of lubricating oil during operation, reducing friction and wear, thereby improving sealing performance and extending service life. The number and position of the oil outlet holes 3 are carefully designed to ensure even distribution of the lubricating oil. A reinforcement ring 4 is fixedly connected to the inside of the ring body 1 and is made of a high-strength metal material (such as stainless steel or aluminum alloy) to enhance the structural strength and stability of the ring body 1. The design of the reinforcement ring 4 can effectively resist external pressure and impact, ensuring that the sealing ring is not easily deformed under high-load working conditions.

[0023] An oil-soaked sponge 5 is fixedly attached to the interior of the ring body 1. Made of a special sponge material, it effectively absorbs and stores lubricating oil. This sponge gradually releases lubricating oil during operation, maintaining the seal ring's lubrication, reducing friction and wear, and ensuring durable sealing performance. A reinforcement layer 6 is fixedly attached to the exterior of the ring body 1. Made of a high-strength composite material (such as reinforced plastic or a metal coating), this layer further enhances the seal ring's wear resistance and compressive strength. This layer is designed to effectively protect the ring body 1 from external environmental influences such as corrosion, abrasion, and impact. Made of polyurethane (PU), this material offers excellent wear resistance, elasticity, and tear resistance, allowing it to withstand high pressure and impact. An anti-corrosion layer 7 is also fixedly attached to the exterior of the ring body 1. Made of an epoxy resin coating, it offers excellent adhesion and corrosion resistance, providing protection in harsh environments. The exterior of the reinforcement layer 6 is fixedly attached to the interior of the anti-corrosion layer 7.

[0024] Working principle: When the sealing ring is installed in the mechanical equipment and starts to run, the ring body 1 is made of polytetrafluoroethylene, which has excellent corrosion resistance and high temperature resistance and can withstand harsh working environments. As the equipment is running, the friction block 2 comes into contact with other components, and the low friction coefficient of PTFE is used to reduce friction loss and ensure the sealing effect. On the outside of the sealing ring, the oil outlet 3 continuously transports lubricating oil to the inside of the ring body 1 to ensure that the lubricating oil can be evenly distributed. The oil-soaked sponge 5 absorbs and stores the lubricating oil, and gradually releases the lubricating oil during operation to maintain the lubrication state of the sealing ring, thereby reducing friction and wear and ensuring the durability of the sealing performance. At the same time, the internal reinforcement ring 4 enhances the structural strength of the ring body 1, enabling it to resist external pressure and impact, and ensure that it is not easily deformed under high load conditions. The external reinforcement layer 6 is made of polyurethane, which further improves the wear resistance and pressure resistance of the sealing ring and protects the ring body 1 from the influence of the external environment. The epoxy resin coating of the anti-corrosion layer 7 provides additional protection for the sealing ring, ensuring that it can maintain good performance in harsh environments. Through the synergistic effect of the above-mentioned components, the high-strength self-lubricating sealing ring can effectively maintain its sealing performance under various working conditions, extend the service life of the equipment, and reduce maintenance frequency.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
