Description

Technical Field

[0001] This utility model relates to the field of oil seal technology, and in particular to a split-type V-shaped fabric-reinforced oil seal. Background Technology

[0002] With the development of industrial automation and machinery, the requirements for the sealing performance of hydraulic systems are increasing. As a new type of sealing component, the split V-type fabric-reinforced oil seal has gradually gained widespread attention in the engineering field due to its superior sealing performance and ease of use. This device consists of multiple layers of oil seals and achieves a highly efficient sealing effect through a special design, effectively isolating liquid and gas leaks. Its advantages include adaptability to harsh working environments such as high pressure and high temperature, improving the overall operational stability of the equipment. Meanwhile, with the increasing demand for production efficiency and ease of maintenance, research and development of new sealing technologies has become one of the important directions in the current industrial field.

[0003] In existing technologies, hydraulic systems typically employ simple rubber seals and O-rings to prevent fluid leakage. These traditional sealing elements rely primarily on the elasticity of the material for sealing. Under operating pressure, the sealing lips are prone to deformation or wear and failure, leading to hydraulic oil leakage. Furthermore, the common connection points in such sealing devices lack sufficient strength during operation, making them vulnerable to high-load conditions. The sealing structures are often designed in a relatively simple manner, failing to meet the diverse needs of industrial applications, resulting in limited sealing performance and impacting the stable operation of equipment.

[0004] However, existing sealing technologies have significant shortcomings in terms of disassembly and maintenance. Traditional sealing devices require complete disassembly of the equipment for replacement and maintenance. This process is cumbersome and time-consuming, resulting not only in high labor costs but also a significant reduction in production efficiency. This is particularly evident in large hydraulic systems, where the complexity and tight connections of the components make routine maintenance even more difficult. Therefore, there is an urgent need for a new sealing solution that can simplify the maintenance process and improve equipment operating efficiency. To address this, a split V-type fabric-reinforced combination oil seal is proposed to solve the aforementioned problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a split-type V-shaped fabric-insulated combination oil seal, which aims to improve the problem of cumbersome sealing and disassembly in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The split-type V-shaped fabric-reinforced oil seal includes multiple oil seals stacked together. Each oil seal has an internal break, and the breaks are staggered and can be fixed by a cap screw.

[0008] As a further description of the above technical solution:

[0009] A connecting groove is provided inside the fracture surface, and a sealing groove is provided inside the fracture surface. The connecting groove communicates with the sealing groove.

[0010] As a further description of the above technical solution:

[0011] The bottom of the oil seal is fixedly connected to a V-shaped sealing plate, and the outer wall of the V-shaped sealing plate is slidably connected inside the connecting groove.

[0012] As a further description of the above technical solution:

[0013] The V-shaped sealing plate is used to form a seal and improve sealing efficiency.

[0014] As a further description of the above technical solution:

[0015] The bottom of the V-shaped sealing plate is fixedly connected to a sealing block, and the outer wall of the sealing block is slidably connected inside the sealing groove.

[0016] As a further description of the above technical solution:

[0017] The oil seal has a limiting groove inside, and an elastic limiting plate is fixedly connected to the bottom of the sealing block. The outer wall of the elastic limiting plate is slidably connected inside the limiting groove.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, the split V-type combined seal, through the V-shaped sealing plate and the sealing block, allows it to be combined with the connecting groove and the sealing groove, improving concentricity and sealing performance. Replacement only requires removing the cylinder head screws, which is convenient and quick. At the same time, during connection, the elastic limiting plate engages inside the limiting groove to limit the position and maintain stability, significantly reducing disassembly and assembly time and labor costs. It solves the problem of cumbersome disassembly and assembly of traditional seals, and improves the convenience of equipment maintenance and work efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a split V-shaped fabric-reinforced oil seal, comprising multiple oil seals 1 stacked together to enhance sealing performance and adapt to the needs of different working environments. Each oil seal 1 has an internal break 2, which are staggered and interconnected, enhancing the overall airtightness of the oil seals 1. The seals 1 can be secured together using pressure cap screws, effectively preventing loosening or displacement during operation. Each break 2 has an internal connecting groove 3 and a internal sealing groove 5, which communicate with each other to ensure stable pressure within the sealing cavity and prevent liquid leakage. This design not only improves the sealing performance of oil seal 1, but also reduces oil leakage caused by untimely maintenance or material aging, further optimizing the operating efficiency of the equipment. A V-shaped sealing plate 4 is fixedly connected to the bottom of oil seal 1. The outer wall of the V-shaped sealing plate 4 is slidably connected to the inside of the connecting groove 3. The V-shaped sealing plate 4 is used to form a seal and improve the sealing efficiency. A sealing block 6 is fixedly connected to the bottom of V-shaped sealing plate 4. The outer wall of the sealing block 6 is slidably connected to the inside of the sealing groove 5. A limiting groove 8 is opened inside oil seal 1. An elastic limiting plate 7 is fixedly connected to the bottom of sealing block 6. The outer wall of the elastic limiting plate 7 is slidably connected to the inside of the limiting groove 8.

[0027] Working Principle: The split V-type combination seal features a V-shaped sealing assembly composed of multiple sealing units. This helps maintain a stable sealing state during operation. When the hydraulic cylinder is running, the internal pressure causes the sealing lip to be squeezed, making it fit more tightly against the cylinder wall. This compression effectively prevents fluid leakage. Elastic materials are provided on both sides of the V-shaped sealing plate 4 to adapt to changes in hydraulic oil pressure. Under high pressure, the sealing lip design ensures strong sealing capability and avoids material aging and deformation under high temperature or pressure. The break 2 and connecting groove 3 of each sealing unit are enhanced... The enhanced sealing flexibility allows it to maintain good sealing performance under different working conditions. In addition, the configuration of the sealing groove 5 and sealing block 6 provides additional support for the seal, ensuring that the seal will not fall off or fail during operation. At the same time, when connecting the oil seal 1, its bottom elastic limiting plate 7 slides into the limiting groove 8 opened in the bottom oil seal 1 for limiting, improving the connection stability. This not only improves the durability and reliability of the seal, but also simplifies the disassembly and maintenance process. When replacing and repairing, only some components of the oil cylinder need to be disassembled, thereby saving time and labor costs and significantly enhancing the overall working efficiency of the equipment.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
