Technical Field

[0001] The utility model relates to the technical field of rubber sealing pieces, in particular to a reusable rubber sealing piece. Background Art

[0002] Rubber sealing rings appear in various fields of our lives, such as bolted connections, the inside of fuel tank caps, etc. Most of the current rubber rings are directly sleeved on the outside of the tight connection parts, or directly placed on the inside of the cylinder cover. For example, in the flange connection of chemical pipelines, rubber gaskets can fill the tiny gap between the flange surfaces when the bolts are tightened to prevent leakage of chemical media.

[0003] At present, a Chinese utility model with the announcement number CN216975764U discloses a rubber seal, which includes a seal body, an opening on one side of the seal body, a fixing groove at one end of the opening, a fixing strip at the other end of the opening, the other end of the fixing strip being detachably arranged inside the fixing groove, and a first shock-absorbing groove and a second shock-absorbing groove being provided on the outside of the seal body, a first shock-absorbing assembly being provided inside the first shock-absorbing groove, and a second shock-absorbing column being provided inside the second shock-absorbing groove. This utility model belongs to the technical field of rubber seals, and specifically provides a rubber seal with a simple structure, good use effect, easy installation of the rubber sealing ring, convenient replacement of the spring inside the rubber sealing ring, saving installation time and reducing installation cost.

[0004] When the existing rubber sealing ring is installed between the flanges, the rubber sealing ring has a simple structure and is generally weak in strength and pressure resistance. Therefore, the extrusion generated during the installation process may cause the rubber sealing ring to deform and break. When the rubber sealing ring on the inner side of the flange needs to be removed for subsequent maintenance or overhaul, the original shape of the rubber sealing ring is destroyed and it can no longer be used, so a new rubber sealing ring needs to be replaced, thereby increasing the maintenance workload and cost. Therefore, a reusable rubber seal is proposed to solve the above-mentioned problems. Utility Model Content

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.

[0028] Moreover, the technical solutions between the various embodiments of the present invention may be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them.

[0029] The utility model provides a reusable rubber seal, which aims to solve the problem that when the existing rubber sealing ring is installed between flanges, the rubber sealing ring has a simple structure and relatively general strength and pressure resistance. Therefore, the extrusion generated during the installation process may cause the rubber sealing ring to be deformed and damaged. When the rubber sealing ring on the inner side of the flange needs to be removed for subsequent maintenance or inspection, the original shape of the rubber sealing ring is destroyed and it can no longer be used, so a new rubber sealing ring needs to be replaced, thereby increasing the maintenance workload and cost.

[0030] like Figure 1-6 As shown, a reusable rubber seal provided by an embodiment of the present invention includes an inner liner 1, screw holes 2 are opened around the top of the inner liner 1, and pressure-resistant components 3 are provided on the top and bottom of the inner liner 1;

[0031] The pressure-resistant component 3 includes a buffer pad 301 fixedly connected to the top and bottom of the inner liner 1. Through holes 302 are provided on all four sides of the top of the buffer pad 301, and the through holes 302 are connected to the screw holes 2. A pressure-resistant and wear-resistant pad 303 is fixedly connected to the outside of the buffer pad 301. Connecting holes 304 are provided on all four sides of the top of the pressure-resistant and wear-resistant pad 303, and the connecting holes 304 are connected to the through holes 302. A shaping strip ring 305 is embedded in the outside of the pressure-resistant and wear-resistant pad 303.

[0032] In the technical solution of the present invention, a pressure-resistant component 3 is provided, and the inner liner 1 is placed in the flange. The connecting parts such as bolts are passed through the connecting holes 304 on the pressure-resistant and wear-resistant pad 303, the through holes 302 on the buffer pad 301, and the screw holes 2 around the top of the inner liner 1 in sequence to fix it together with the flange. When the bolts are tightened, the flange will generate an extrusion force on the pressure-resistant component 3. At this time, the buffer pad 301 in the pressure-resistant component 3 is compressed first to absorb part of the extrusion force. At the same time, the pressure-resistant and wear-resistant pad 303 and the embedded shaping strip ring 305 jointly bear the pressure to keep the shape of the inner liner 1 stable. When the pipeline system is operating normally, the inner liner 1 exerts basic sealing performance to prevent fluid leakage, and the pressure-resistant component 3 protects the inner liner 1 from external pressure and friction, the pressure-resistant and wear-resistant pad 303 resists the erosion from the fluid inside the pipeline and the friction from the external environment, ensuring that the surface of the inner liner 1 is not damaged, and the shaping ring 305 always maintains its shape to ensure the stability of the sealing effect of the inner liner 1. When maintenance or inspection is required, the flange is removed. Since the pressure-resistant and wear-resistant pad 303 has good pressure and wear resistance and the support of the shaping ring 305, the shape of the inner liner 1 is not easily destroyed. After simple cleaning and inspection, it is reinstalled according to the installation steps and continued to be used. In summary, through the synergistic effect of the inner liner 1, the screw hole 2 and the pressure-resistant component 3, different functions are exerted at each stage, thereby improving the pressure resistance of the rubber seal, enhancing wear resistance, reusability and convenient installation.

[0033] Please refer to Figure 4 Pull pads 4 are fixedly connected to the outer sides of the inner liner 1 on all sides. The outer sides of the pull pads 4 are curved and made of rubber material. In this embodiment, the provision of the pull pads 4 provides an area for the operator to grasp and apply force during installation and removal, making it easier to place the inner liner 1 in and remove it from the flange. The rubber material has a certain degree of flexibility, which does not cause damage to the operator's hands, but also provides good friction when grasping to prevent slipping.

[0034] For further information, please refer to Figure 4 The top and bottom of the pull pad 4 are both embedded with anti-slip lines 5, which are in the shape of threaded rings. In this embodiment, by providing the anti-slip lines 5, during the installation process, when the inner liner 1 is placed between the flanges and subjected to the tightening force of the bolts, the anti-slip lines 5 can increase the friction between the pull pad 4 and the flanges, preventing the inner liner 1 from shifting under the action of pressure. This helps to ensure that the inner liner 1 always remains in the correct position and ensures the stability of the sealing performance. In addition, due to the presence of the anti-slip lines 5, the inner liner 1 is more stable during installation and is less likely to become skewed or misaligned, thereby improving the accuracy of installation.

[0035] Please continue to refer to Figure 5 The interior of the screw hole 2 is fixedly connected with a reinforcement sleeve 6, and the top and bottom of the reinforcement sleeve 6 are respectively located inside the through hole 302 and the connection hole 304. In this embodiment, by providing the reinforcement sleeve 6, the strength of the screw hole 2 can be significantly enhanced. When the bolt passes through the screw hole 2 for tightening, the reinforcement sleeve 6 can withstand greater tension and shear force, preventing the screw hole 2 from being deformed or damaged due to excessive force. Especially during multiple installation and disassembly processes, the reinforcement sleeve 6 can extend the service life of the screw hole 2 and ensure that the connection between the inner liner 1 and the flange is firm and reliable.

[0036] Please refer to Figure 5 The outer side of the top of the reinforcement sleeve 6 is fixedly connected with an inserting collar 7, which is located on the outer side of the pressure-resistant wear-resistant pad 303. In this embodiment, by providing the inserting collar 7, the inserting collar 7 is located on the outer side of the pressure-resistant wear-resistant pad 303. When installing the bolts, it can play a guiding role, making it easier and more accurate to insert the bolts into the connecting hole 304, the through hole 302 and the screw hole 2, which helps to improve the efficiency of installation and reduce errors and time waste during the installation process. In addition, the outer side of the inserting collar 7 can be inserted into the hole on the outer side of the flange, thereby ensuring stability during installation and connection.

[0037] Also, please refer to Figure 6The inner liner 1 is fixedly connected to an inner fixing sleeve 8, which is made of an alloy material. In this embodiment, the inner fixing sleeve 8 is fixedly connected to the inner liner 1 and is made of an alloy material. Alloy materials generally have high strength and hardness. The inner fixing sleeve 8 can provide additional support and strength for the inner liner 1, making it more stable when subjected to pressure and friction. Especially when the fluid pressure inside the pipeline is high, the inner fixing sleeve 8 can prevent excessive deformation of the inner liner 1, ensuring that the sealing performance is not affected.

[0038] Also, please refer to Figure 6 A guide groove 9 is provided inside the inner fixed sleeve 8. The guide groove 9 is in a semicircular shape. In this embodiment, the guide groove 9 can play a role in guiding the flow. In the pipeline system, the flow of the fluid may generate vortexes or turbulence. The guide groove 9 can guide the fluid to pass smoothly through the inner liner 1, reducing the impact and wear of the fluid on the inner liner 1. At the same time, the guide groove 9 can also help to discharge impurities and bubbles that may accumulate near the inner liner 1, keeping the sealing area clean.

[0039] Also, please refer to Figure 1 The inner liner 1 is made of rubber material, and the interior of the reinforcement sleeve 6 is sprayed with a wear-resistant coating. In this embodiment, the wear-resistant coating can reduce the friction and wear between the bolt and the reinforcement sleeve 6. During the installation and removal of the bolt, as well as under the vibration and pressure changes during the operation of the pipeline system, relative movement occurs between the bolt and the reinforcement sleeve 6. The wear-resistant coating can reduce the wear caused by this movement, extending the service life of the reinforcement sleeve 6 and the bolt. Reducing wear can ensure that the connection between the bolt and the reinforcement sleeve 6 is always tight and reliable, preventing loosening or leakage caused by wear. This is very important for long-term operation of the pipeline system and can improve the stability and safety of the system.
