sealing mechanism

Abstract

This application relates to a sealing mechanism. The sealing mechanism includes an elastic seal and a fastener. The elastic seal has a ring-shaped structure and is used to cover the pipe connection. The inner wall of the fastener is provided with a sealing groove for the elastic seal to be embedded in. At least one of the elastic seal and the fastener is provided with an elastic sealing protrusion for abutting against the other of the elastic seal and the fastener. The fastener presses the elastic seal against the pipe connection, and the elastic seal can tightly cover the pipe connection, forming the first line of sealing defense. When the elastic seal is embedded in the sealing groove of the fastener, if there is a slight height difference or structural deformation between the pipes, the elastic sealing protrusion will abut against the opposite component, further increasing the sealing contact area and the tightness of the seal, thereby effectively preventing the medium inside the pipe from leaking into the external environment and the medium in the external environment from seeping into the pipe, forming multiple sealing protections.

Description

Technical Field

[0001] This application relates to the field of sealing structure technology, and in particular to sealing mechanisms. Background Technology

[0002] In engineering applications, there are many problems with the sealing technology for cable and duct connections.

[0003] Currently, there are several main methods for connecting cable conduits: First, metal fasteners are used. This method lacks waterproof sealing, and in environments where conduits are buried underground or underwater, rainwater and groundwater can easily seep into the conduit, causing short circuits due to water immersion, component aging, and other malfunctions, severely affecting the normal operation of the wiring within the conduit. Second, some cable conduit connections use curing adhesives for sealing. However, these adhesives permanently connect the conduits, making disassembly during maintenance difficult. Third, flange connections are used. These involve slotting the flange connection surface and installing conventional elastic seals such as nitrile rubber flat rings and O-rings. However, due to generally poor pipe processing and assembly precision, it is difficult to ensure that the compression and filling of the elastic seals meet operational requirements, leading to leakage. Furthermore, the aging of the elastic seals themselves can cause seal failure. Additionally, flange processing is time-consuming and expensive, and disassembly for maintenance in confined spaces is extremely difficult. This not only increases project costs but also causes significant inconvenience for later maintenance. Utility Model Content

[0015] In one embodiment, the connecting body is provided with a first cavity, and the pressure-resistant support is disposed within the first cavity.

[0016] In one embodiment, the end face of the elastic sealing body is provided with a second cavity, which communicates with the first cavity;

[0017] One end of the compression-resistant support is disposed in the first cavity, and the other end is disposed in the second cavity.

[0018] In one embodiment, a first adhesive layer is bonded between the compression support and the inner wall of the first cavity; and / or

[0021] The dovetail tenon can extend into the dovetail groove and is interference-fitted with the dovetail groove, so that the dovetail tenon is locked and fixed in the connecting groove.

[0022] In one embodiment, the fastener is provided with a first fastening sealing surface and a second fastening sealing surface along the axial direction of the pipe. The first fastening sealing surface is used to abut against the outer wall surface of one of the pipes, and the second fastening sealing surface is used to abut against the outer wall surface of the other pipe.

[0023] The sealing groove is disposed between the first fastening sealing surface and the second fastening sealing surface.

[0024] In one embodiment, the sealing groove includes:

[0025] The bottom wall of the groove is used to abut against the circumferential outer wall surface of the elastic seal;

[0026] The groove sidewall is used to abut against the axial end face of the elastic seal;

[0027] The elastic sealing protrusion is disposed between the bottom wall of the groove and the circumferential outer wall of the elastic sealing element.

[0028] In one embodiment, the circumferential outer wall surface of the resilient seal is provided with the resilient sealing protrusion facing the bottom wall of the groove; and / or

[0029] The bottom wall of the groove is provided with an elastic sealing protrusion facing the circumferential outer wall surface of the elastic seal.

[0030] In one embodiment, when the circumferential outer wall of the elastic seal is provided with the elastic sealing protrusion facing the bottom wall of the groove, the elastic sealing protrusion is integrally formed with the elastic seal.

When the elastic seal is embedded in the sealing groove of the fastener, the elastic sealing protrusion will abut against the opposite component, further increasing the sealing contact area and the tightness of the seal. This is equivalent to adding another line of sealing defense on the basis of the original seal, thereby effectively preventing the medium in the pipe from leaking into the external environment and the medium in the external environment from seeping into the pipe, forming multiple sealing protections. Since both the elastic seal and the elastic sealing protrusion are elastic, when the pipe undergoes slight deformation due to factors such as temperature changes and external forces, resulting in bending at the pipe connection, the elastic seal and the elastic sealing protrusion can adapt to this change through their own elastic deformation, always maintaining close contact with the pipe and the fastener, maintaining a good sealing effect, making up for the engineering problems of low processing precision and slight structural deformation that are common in pipes, and ensuring effective sealing of the pipe connection.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0070] In engineering applications, there are various sealing technologies for cable conduits and lubrication systems, but all of them have some problems:

[0071] Metal fasteners are commonly used in engineering for cable conduit connections. This method offers the advantage of convenient installation, allowing for quick and easy connection and fixation of cables and conduits. However, its biggest drawback is the lack of waterproof sealing. In practical applications, cable conduits are often located underground or underwater. When using metal fasteners, rainwater and groundwater can easily seep into the conduit through the gaps. This can lead to water damage to the wiring, causing short circuits, and can also cause corrosion and aging of internal components, severely impacting the normal operation and lifespan of the cable conduit.

[0072] Some cable conduits are sealed using hardened adhesives during connection. These adhesives fill gaps at the joints, preventing moisture and contaminants from entering the conduit and thus providing a seal. However, hardened adhesives permanently connect the conduits, making disassembly for maintenance difficult. Furthermore, after curing, the adhesive may age and crack due to long-term environmental factors such as temperature and humidity changes, reducing its sealing performance.

[0073] In addition, pipe connections can typically use flange structures, with conventional sealing elements such as nitrile rubber flat rings and O-rings installed in grooves on the flange end face. However, flange manufacturing is complex, requiring precise grooving on the end face, resulting in a long processing cycle and high costs. Furthermore, in confined spaces, if a pipe malfunctions and requires disassembly for maintenance, the complex flange structure and limited operating space significantly complicate the work, increasing maintenance costs and time. Moreover, the generally poor precision in pipe processing and assembly makes it difficult to ensure the compression and filling of the seals meet operational requirements, leading to leaks. Furthermore, aging of the seals themselves can cause seal failure.

[0074] Based on the above considerations, in order to alleviate the above problems, the inventors, after in-depth research, designed a sealing mechanism 1000. Through the cooperation of the elastic sealing element 100, the fastening element 200 and the elastic sealing protrusion 300, the sealing mechanism 1000 has a good sealing effect.

[0075] See Figure 1 and Figure 2 At least one embodiment of this application provides a sealing mechanism 1000, which includes an elastic sealing element 100 and a fastener 200. The elastic sealing element 100 has a ring-shaped structure and is used to cover the connection of the pipes 2000, specifically the connection of two adjacent pipes 2000. The inner wall of the fastener 200 is provided with a sealing groove 201 for the elastic sealing element 100 to be embedded in. At least one of the elastic sealing element 100 and the fastener 200 is provided with an elastic sealing protrusion 300 for abutting against the other of the elastic sealing element 100 and the fastener 200.

[0076] In some embodiments, see Figure 3 When the elastic sealing protrusion 300 is provided on the elastic sealing element 100, it is used to abut against the fastening element 200; see reference Figure 4 When the elastic sealing protrusion 300 is provided on the fastener 200, it is used to abut against the elastic sealing element 100. It is understood that, see [reference needed] Figure 5 While the elastic sealing protrusion 300 is provided on the elastic sealing element 100, the elastic sealing protrusion 300 can also be provided on the fastener 200. As long as the elastic sealing protrusion 300 on the elastic sealing element 100 and the elastic sealing protrusion 300 on the fastener 200 are staggered to avoid mutual interference.

[0077] According to the sealing mechanism 1000 of this application embodiment, the fastener 200 presses the elastic seal 100 against the connection of the pipe 2000. The elastic seal 100 has a ring-shaped structure and can tightly cover the connection of the pipe 2000, forming a first sealing line between the contact surfaces of the elastic seal 100 and the pipe 2000, and a second sealing line between the contact surfaces of the elastic seal 100 and the fastener 200. The sealing groove 201 can completely accommodate the elastic seal 100. When the elastic seal 100 is embedded in the sealing groove 201 of the fastener 200, in the axial direction of the pipe 2000, due to the sealing groove 201... The fastener 200 is designed to tightly wrap around the axial ends of the elastic seal 100 on both sides of the axial direction, forming a third line of defense. When there is a slight height difference or structural deformation between the pipes 2000, the elastic seal protrusion 300 will abut against the opposite component, further increasing the contact area and tightness of the seal. This is equivalent to adding another line of defense on the basis of the original seal. Thus, when there is a medium inside the pipe 2000, it effectively prevents the medium inside the pipe 2000 from leaking into the external environment. When the inside of the pipe 2000 is a wiring device, it effectively prevents the medium in the external environment from seeping into the pipe 2000, forming multiple layers of sealing protection. Since both the elastic seal 100 and the elastic sealing protrusion 300 are elastic, when the pipe 2000 undergoes slight deformation due to factors such as temperature changes or external forces, resulting in bending at the connection of the pipe 2000, the elastic seal 100 and the elastic sealing protrusion 300 can adapt to the change through their own elastic deformation, always maintaining close contact with the pipe 2000 and the fastener 200, maintaining a good sealing effect, compensating for the engineering problems of low processing precision and slight structural deformation that are common in pipes 2000, and ensuring effective sealing of the connection of pipe 2000.

[0078] Furthermore, the contact between the elastic sealing protrusion 300 and the opposing component makes the fit between the elastic sealing element 100 and the fastener 200 tighter and more secure. This tight fit prevents the elastic sealing element 100 from shifting or loosening under the influence of external forces or vibrations on the pipe 2000, ensuring the reliability and stability of the sealing mechanism 1000 during long-term use. Because the elastic sealing element 100 has a certain elastic deformation capacity, the sealing mechanism 1000 can adapt to pipes 2000 of different diameters within a certain range, eliminating the need to design and manufacture a separate sealing mechanism 1000 for each pipe diameter, thus improving the versatility and economy of the sealing mechanism 1000.

[0079] It is understood that in the elastic seal 100 and elastic sealing protrusion 300 of this application embodiment, elasticity refers to the property of a material to return to its original shape and size after being deformed by force and the external force is removed. In the sealing mechanism 1000, the materials used for the elastic seal 100 and elastic sealing protrusion 300 are usually high-molecular materials such as rubber and polyurethane with good elasticity. The elastic structure of these materials has a certain degree of flexibility and deformability. When subjected to external force, it will deform, but it will return to its initial state after the external force is removed.

[0080] Specifically, the elastic seal 100 has a ring-shaped structure and is used to cover the connection of the pipe 2000. Its elasticity allows it to be stretched and fitted onto the pipe 2000 during installation, and then tightly adheres to the surface of the pipe 2000 by its own elastic contraction force. Even if there is a certain dimensional tolerance in the outer diameter of the pipe 2000, the elastic seal 100 can adaptively adjust the contact pressure with the pipe 2000 through elastic deformation to ensure a tight seal. In actual use, the pipe 2000 may undergo slight deformation due to factors such as temperature changes, external forces, or external vibrations. The elasticity of the elastic seal 100 allows it to change shape accordingly with the deformation of the pipe 2000, always maintaining good contact with the pipe 2000 and avoiding gaps caused by pipe 2000 deformation, thereby ensuring the stability of the sealing effect. During the assembly process of the sealing mechanism 1000, there may be certain assembly errors, such as concentricity deviation between the elastic seal 100 and the pipe 2000. The elasticity of the elastic seal 100 can compensate for these errors to a certain extent, and adjust its position and shape through its own deformation, so that the sealing mechanism 1000 can work normally.

[0081] Specifically, the resilient sealing protrusion 300 is disposed in at least one of the resilient seal 100 and the fastening member 200 for abutting against the other. Its elasticity allows the resilient sealing protrusion 300 to be compressed during installation of the sealing mechanism 1000, generating an elastic reaction force, thereby increasing the contact pressure with the opposing component. This greater contact pressure effectively prevents media leakage and improves sealing performance. The surfaces of the fastening member 200 and the resilient seal 100 may have a certain degree of roughness or minor unevenness. The elasticity of the resilient sealing protrusion 300 allows it to deform and fill the minor depressions on these uneven surfaces when in contact, forming a tight or continuous sealing line, further improving the reliability of the seal.

[0082] In some embodiments, the resilient seal 100 is used in conjunction with the fastener 200. The design should ensure that, after the fastener 200 is locked, the cross-section of the resilient seal 100 is compressed by at least 25% in the direction perpendicular to the pipe extension direction, i.e., the radial direction of the pipe. This ensures that the resilient seal 100 can undergo sufficient elastic deformation when compressed by the fastener 200. By fully compressing the resilient seal 100, it can fit tightly between the outer wall of the pipe 2000 and the inner wall of the fastener 200, filling any gaps and forming an effective sealing barrier. If the compression is less than 25%, the resilient seal 100 may not deform sufficiently to fill the gaps, resulting in decreased sealing performance, easy leakage of the medium inside the pipe 2000, and leakage of the medium from the external environment into the pipe 2000.

[0083] In some embodiments, the resilient seal 100 uses a long-life sealing material, and in combination with actual working conditions, selects a compression amount of 25%-35% and a filling amount of 80%-90% to achieve a long service life and a reliable sealing effect.

[0084] In some embodiments, the cross-sectional area of ​​the resilient seal 100 is not less than 75% of the installation space between the pipe 2000 and the fastener 200. This ensures that the resilient seal 100 occupies sufficient volume within the installation space. A larger cross-sectional area means that the resilient seal 100 can better fill the space between the pipe 2000 and the fastener 200, reducing leakage pathways. When the cross-sectional area of ​​the resilient seal 100 reaches more than 75% of the installation space, the possibility of media leakage through the tiny gaps between the resilient seal 100 and the pipe 2000 and the fastener 200 can be effectively reduced.

[0085] Understandably, the design of the elastic sealing protrusion 300, compared to increasing the overall compression and filling amount of the elastic seal 100, can reduce the sacrifice in service life of the elastic seal 100 caused by increasing the compression. Specifically, increasing the overall compression and filling amount of the elastic seal 100 can indeed enhance the sealing effect to some extent, because a larger compression and filling amount allows the elastic seal 100 to fit more tightly against the pipe 2000 and the fastener 200, reducing leakage gaps. However, excessive compression will cause significant stress to the elastic seal 100. When the elastic seal 100 is under high stress for a long time, its internal polymer chains will gradually fatigue and break, accelerating the aging and deformation of the elastic seal 100, causing it to lose its elasticity and be unable to return to its initial shape, thus shortening its service life. The elastic sealing protrusion 300 fills the sealing gap through its own elastic deformation, achieving the purpose of enhancing the sealing effect. Unlike increasing the overall compression and filling amount of the elastic seal 100, the elastic seal protrusion 300 only deforms and seals at critical locations, without requiring significant compression of the entire elastic seal 100. This design results in a smaller increase in stress on the elastic seal 100, preventing premature aging and failure due to excessive overall compression. The elastic seal protrusion 300 achieves a good sealing effect through localized elastic deformation while minimizing the negative impact of increased overall compression on the lifespan of the elastic seal 100. This reduces maintenance costs and the frequency of replacing the elastic seal 100, improving the stability and reliability of the pipeline 2000 system.

[0086] See Figure 6 and Figure 7 In some embodiments, the resilient seal 100 includes a resilient sealing body 110 and a connector 120. The resilient sealing body 110 has a strip-shaped structure and is provided with a first end 111 and a second end 112 opposite to each other. The first end 111 is provided with a connecting groove 1111. The connector 120 is disposed at the second end 112 and can be inserted into the connecting groove 1111. (See reference...) Figure 8 and Figure 9 The first end 111 and the second end 112 of the elastic sealing body 110 are connected in a ring structure. Specifically, the ring structure can be obtained by bending the elastic sealing member 100 with a strip structure. The connector 120 is locked and fixed in the connecting groove 1111.

[0087] With the above configuration, the elastic sealing body 110 adopts a strip-shaped structure. During the actual installation of the sealing mechanism 1000, the operator can bend the strip-shaped elastic sealing body 110 around the pipe 2000 according to the specific size and shape of the pipe 2000. Then, through the cooperation of the connector 120 and the connecting groove 1111, it is connected into a ring structure, adapting to pipes 2000 of different specifications, thus improving the flexibility and efficiency of installation. The connector 120 can be directly inserted into the connecting groove 1111, allowing the operator to complete the assembly of the elastic sealing element 100 simply by accurately inserting the connector 120 into the connecting groove 1111, greatly shortening the installation time. This is especially suitable for engineering scenarios that require rapid sealing operations. When the first end 111 and the second end 112 of the elastic sealing body 110 are connected into a ring structure through the connector 120 and the connecting groove 1111, the connector 120 is locked and fixed in the connecting groove 1111. This ensures that the elastic sealing element 100 forms a complete and continuous sealing ring structure at the pipe 2000 connection. This tight connection effectively prevents media leakage and improves the reliability of the seal. The elastic seal 100 itself is elastic; even if the pipeline 2000 undergoes slight deformation due to temperature changes, external forces, or other factors during use, the elastic seal body 110 can adapt to the change through its own elastic deformation, maintaining a tight fit with the pipeline 2000. Simultaneously, the locking structure between the connector 120 and the connecting groove 1111 ensures that the connection at both ends will not loosen when the elastic seal 100 deforms, further enhancing the stability of the seal.

[0088] Understandably, since the connection between the connector 120 and the connecting groove 1111 is detachable, in some cases, when the pipeline 2000 needs to be repaired or modified, the elastic seal 100 can be disassembled and reinstalled after the repair or modification is completed, thus realizing the reuse of the elastic seal body 110 and saving resources.

[0089] It is understood that the first end 111 and the second end 112 of the elastic seal 100 in this embodiment are connected in a ring structure, which is not limited to a circular ring structure. Because the elastic seal 100 itself is elastic and deformable, it can adapt to pipes 2000 of different diameters and shapes. Whether the pipe 2000 is circular, square, or other irregularly shaped, as long as the elastic seal body 110 is bent into the corresponding shape and connected by the connector 120 and the connecting groove 1111, an effective seal can be formed, expanding the applicability of the sealing mechanism 1000. The sealing mechanism 1000 is not limited by the cross-sectional shape and size of the pipe 2000 and can be modified according to different cross-sections.

[0090] In some embodiments, the connecting groove 1111, the connector 120 and the elastic sealing body 110 are made of long strip rubber strips and are integrally formed by molding or microwave vulcanization to form the elastic sealing element 100.

[0091] See Figure 7 In some embodiments, the connecting groove 1111 is configured as a dovetail groove made of a first elastic material, and the connecting member 120 is configured as a dovetail tenon made of a second elastic material; the dovetail tenon can extend into the dovetail groove and is interference-fitted with the dovetail groove, so that the dovetail tenon is locked and fixed in the connecting groove 1111. The dovetail groove, the dovetail tenon and the elastic sealing body 110 are integrally formed to form the elastic sealing member 100. The integrally formed elongated elastic sealing body 110 has a dovetail groove structure and a dovetail tenon structure on both sides. By bending the elastic sealing member 100, the dovetail groove and the dovetail tenon are connected to form a hollow shape, covering the outer periphery of the connection between two adjacent pipes 2000.

[0092] See Figure 8 and Figure 9 Specifically, the dovetail groove and dovetail tenon are mechanically locked together using an interference fit. The dovetail tenon is slightly larger than the dovetail groove, and further tightens under pressure, forming a self-locking mechanism. In practical use, the connection between the dovetail groove and dovetail tenon is designed in the middle of the cross-section of pipe 2000, and is located in a easily deformable part in the radial direction of pipe 2000. Simultaneously, this connection structure has self-locking capability; the interference fit of the connection means that under the tightening force of the fastener 200, the greater the tightening force, the tighter the sealing surface fit.

[0093] It is understood that in some embodiments, the elastic seal 100 is made by cutting a rubber strip with an irregular cross-section, which is versatile and not limited to the perimeter of the connection structure of the pipe 2000. Only a rubber mold for preparing the rubber strip with an irregular cross-section is required.

[0094] See Figure 10 In some embodiments, the elastic seal 100 includes an integral elastic sealing ring. With this configuration, the dovetail groove and dovetail tenon connection structure can be eliminated, and a dedicated mold can be used for integral molding via injection vulcanization or compression molding. The elastic sealing ring has no connecting structure; that is, it is a complete annular structure, suitable for applications with higher sealing requirements.

[0095] See Figure 11 In some embodiments, the connector 120 includes a connecting body 121 and a compression support 122. The connecting body 121 is fixed to the second end 112; the compression support 122 is disposed on the connecting body 121. The compression support 122 provides compression support for the connecting body 121, enabling the connecting body 121 to resist deformation.

[0096] In some embodiments, the compression support 122 is configured as a compression support 122 made of metal material, which has a certain supporting capacity and corrosion resistance. Specifically, the metal compression support 122 can be made of corrosion-resistant materials such as stainless steel or aluminum alloy.

[0097] See Figure 11 In some embodiments, the connecting body 121 is provided with a first cavity 1211, and the pressure-resistant support member 122 is disposed in the first cavity 1211.

[0098] Specifically, by using an integrally molded elastic sealing element 100, that is, by using an integrally molded elastic sealing body 110 with a connecting body 121, the side of the connecting body 121 is hollowed out to form a first cavity 1211. Then, the pressure-resistant support element 122 is embedded and bonded into the first cavity 1211. Finally, the dovetail groove and the dovetail tenon are connected. The dovetail groove is located at the elastic sealing body 110 and has elasticity. It is relatively easy to put the dovetail tenon embedded in the pressure-resistant support element 122 into the dovetail groove, which facilitates the connection.

[0099] It is understood that in some embodiments, the elastic sealing member 100 with the first cavity 1211 can be directly integrally molded, that is, the connecting body 121 with the first cavity 1211 and the elastic sealing body 110 are integrally molded, and then the pressure-resistant support member 122 is embedded and bonded in the first cavity 1211.

[0100] See Figure 11 In some embodiments, the elastic sealing body 110 has a second cavity 1121 on the end face of the second end 112, and the second cavity 1121 communicates with the first cavity 1211; one end of the pressure-resistant support member 122 is disposed in the first cavity 1211, and the other end is disposed in the second cavity 1121. Through the above arrangement, the pressure-resistant support member 122 extends further into the second end 112 of the elastic sealing body 110, providing pressure-resistant support for the elastic sealing body 110 and improving its resistance to deformation.

[0101] It is understandable that by integrally molding the elastic sealing element 100, that is, by integrally molding the elastic sealing body 110 with the connecting body 121, the side of the connecting body 121 is hollowed out, and after the connecting body 121 is hollowed out, the elastic sealing body 110 connected to it is further hollowed out to form a first cavity 1211 and a second cavity 1121 that are interconnected. Then, the pressure-resistant support 122 is embedded and bonded into the first cavity 1211 and the second cavity 1121. Alternatively, the elastic sealing element 100 with the first cavity 1211 and the second cavity can be integrally molded, that is, the connecting body 121 with the first cavity 1211 and the elastic sealing body 110 with the second cavity 1121 are integrally molded, and then the pressure-resistant support 122 is embedded and bonded into the first cavity 1211 and the second cavity 1121.

[0102] In some embodiments, a first adhesive layer (not shown) is bonded between the compression support 122 and the inner wall of the first cavity 1211; and / or a second adhesive layer (not shown) is bonded between the compression support 122 and the inner wall of the second cavity 1121. Specifically, the first and second adhesive layers can be formed by applying a rubber adhesive. With the above arrangement, the metal compression support 122 and the elastic seal 100 are bonded together with a rubber adhesive, thereby improving the sealing strength.

[0103] Specifically, in some embodiments, when the elastic seal 100 uses different elastic materials, different adhesives can be selected accordingly. For example, when the elastic seal 100 uses rubber material, different metal-rubber bonding adhesives can be used depending on the type of rubber in the elastic seal 100. The adhesives can be bonded during vulcanization or after vulcanization.

[0104] See Figure 12 In some embodiments, the fastener 200 is provided with a first fastening sealing surface 202 and a second fastening sealing surface 203 along the axial direction of the pipe 2000. The first fastening sealing surface 202 is used to abut against the outer wall of one pipe 2000, and the second fastening sealing surface 203 is used to abut against the outer wall of another pipe 2000. A sealing groove 201 is provided between the first fastening sealing surface 202 and the second fastening sealing surface 203. The fastener 200 is provided with the first fastening sealing surface 202 and the second fastening sealing surface 203 abutting against the outer walls of the two pipes 2000 respectively, and the sealing groove 201 in the middle cooperates with the elastic sealing element 100 to form multiple sealing defenses. For the medium inside pipeline 2000 to leak, it must break through multiple seals, including the elastic seal and sealing groove 201, and the sealing surface and outer wall of pipeline 2000, greatly reducing the possibility of leakage. Similarly, for the medium from the external environment to leak into pipeline 2000, it must also break through multiple seals, including the elastic seal and sealing groove 201, and the sealing surface and outer wall of pipeline 2000, greatly reducing the possibility of leakage. The first and second tight-fitting sealing surfaces 202 and 203 are tightly fitted to the outer wall of pipeline 2000, not only sealing the pipe but also increasing the friction and contact area between the fastener 200 and pipeline 2000, making the fastener 200 more securely fixed to pipeline 2000. This allows it to better withstand temperature changes and external forces during pipeline 2000 system operation, preventing the fastener 200 from loosening. Through these features, the sealing effect is enhanced, structural stability is improved, and the sealing and reliability of pipeline 2000 connections are guaranteed.

[0105] See Figure 12In some embodiments, the sealing groove 201 includes a groove bottom wall 2011 and a groove side wall 2012. The groove bottom wall 2011 is used to abut against the circumferential outer wall surface of the elastic seal 100; the groove side wall 2012 is used to abut against the axial end face of the elastic seal 100; wherein, the elastic sealing protrusion 300 is disposed between the groove bottom wall 2011 and the circumferential outer wall surface of the elastic seal 100. The groove bottom wall 2011 abuts against the circumferential outer wall surface of the elastic seal 100, and the groove side wall 2012 abuts against the axial end face of the elastic seal 100, forming a sealing space surrounding the elastic seal 100. Together with the elastic sealing protrusion 300 located between the groove bottom wall 2011 and the circumferential outer wall surface of the elastic seal 100, they constitute a multi-seal mechanism 1000. The elastic seal 100 itself provides initial sealing, while the elastic sealing protrusion 300 further fills tiny gaps. The bottom wall 2011 and side wall 2012 of the groove restrict the leakage path of the medium, greatly reducing the risk of leakage. Even if some sealing links fail, other parts can still maintain a certain sealing performance. The elastic sealing protrusion 300 is positioned between the bottom wall 2011 of the groove and the circumferential outer wall of the elastic seal 100, compensating for errors during installation to some extent. Even if there is a slight deviation in the installation position of the elastic seal 100, the elastic sealing protrusion 300 can still make tight contact with the bottom wall 2011 of the groove through its own elastic deformation, ensuring a sealing effect, reducing the stringent requirements for installation accuracy, and making the installation operation easier.

[0106] Through the above-described configuration, the tight contact between the bottom wall 2011 and the side wall 2012 of the groove and the elastic seal 100, along with the effect of the elastic seal protrusion 300, secures the elastic seal 100 within the groove. During operation of the pipeline 2000 system, this effectively prevents the elastic seal 100 from shifting or loosening due to temperature changes or external forces, ensuring the long-term stable operation of the sealing mechanism 1000, reducing the cost of frequent replacement and maintenance of the elastic seal, and making it suitable for pipeline 2000 systems that operate long-term and are difficult to maintain.

[0107] In some embodiments, see Figure 12 The circumferential outer wall of the resilient seal 100 is provided with a resilient sealing protrusion 300 facing the bottom wall 2011 of the groove; and / or, see reference Figure 4 and Figure 5 The bottom wall 2011 of the groove is provided with an elastic sealing protrusion 300 facing the circumferential outer wall surface of the elastic seal 100.

[0108] Specifically, the elastic sealing protrusion 300 can be provided only on the circumferential outer wall of the elastic sealing element 100, or only on the bottom wall 2011 of the groove, or multiple elastic sealing protrusions 300 can be provided on both the circumferential outer wall of the elastic sealing element 100 and the bottom wall 2011 of the groove. The key is that the elastic sealing protrusions 300 on the elastic sealing element 100 and the elastic sealing protrusions 300 on the bottom wall 2011 of the groove are staggered to avoid mutual interference. Whether the elastic sealing protrusion 300 is provided on the circumferential outer wall of the elastic sealing element 100, the bottom wall 2011 of the groove, or multiple elastic sealing protrusions 300 on both, the sealing contact points and contact area of ​​the sealing mechanism 1000 are greatly increased. When the fastener 200 is locked, the elastic sealing protrusion 300 is compressed and deformed, which can more tightly fill the tiny gap between the elastic sealing element 100 and the bottom wall 2011 of the groove, effectively preventing media leakage.

[0109] Understandably, the arrangement of the elastic sealing protrusion 300 can be flexibly selected based on the properties of the internal and external media of the pipeline 2000 and the working environment of the pipeline 2000. For conditions with highly corrosive media, multiple elastic sealing protrusions 300 can be provided on both the elastic sealing element 100 and the bottom wall 2011 of the groove to enhance sealing performance; for relatively stable conditions, providing only one elastic sealing protrusion 300 on the elastic sealing element 100 or the bottom wall 2011 of the groove is sufficient to meet the sealing requirements. This flexibility allows the sealing mechanism 1000 to better adapt to various complex engineering application scenarios.

[0110] See Figure 4 In some embodiments, the bottom wall 2011 of the groove is provided with an elastic sealing protrusion 300 facing the circumferential outer wall surface of the elastic seal 100. The elastic sealing protrusion 300 is provided in the bottom wall 2011 of the groove. When the elastic seal 100 is embedded in the sealing groove 201, the protrusion is compressed and undergoes elastic deformation, thereby forming a greater contact pressure between the circumferential outer wall surface of the elastic seal 100 and the bottom wall 2011 of the groove.

[0111] See Figure 12In some embodiments, when the circumferential outer wall of the elastic seal 100 is provided with an elastic sealing protrusion 300 facing the bottom wall 2011 of the groove, the elastic sealing protrusion 300 and the elastic seal 100 are integrally formed. This configuration simplifies the manufacturing process; the integral design avoids the complex process of separately manufacturing and installing the elastic sealing protrusion 300 onto the elastic seal 100, reducing production steps and time, and improving production efficiency. Simultaneously, it reduces errors and scrap rates during production, facilitating large-scale production and lowering production costs. Furthermore, the integral forming makes the elastic sealing protrusion 300 and the elastic seal 100 a single unit, eliminating the connection interface and preventing the protrusion from detaching or loosening due to weak connections. This ensures the integrity and reliability of the sealing mechanism 1000, improving product quality and stability. The integrally formed elastic sealing protrusion 300 can better adapt to the deformation of the elastic seal 100. When the elastic seal 100 changes shape due to the deformation of the pipe 2000 or other factors, the protrusion can deform synchronously and always maintain close contact with the bottom wall 2011 of the groove, thereby improving the adaptability of the sealing mechanism 1000 to different working conditions.

[0112] In some embodiments, see Figure 13 and Figure 14 The resilient sealing protrusion 300 includes an annular sealing protrusion 310 or a circular sealing protrusion 320; and / or, the cross-section of the resilient sealing protrusion 300 includes a semi-circular or rectangular shape. Different shapes of the resilient sealing protrusion 300, such as the annular sealing protrusion 310, the circular sealing protrusion 320, and semi-circular and rectangular cross-sections, can adapt to different working conditions and leakage paths. The annular sealing protrusion 310 can provide uniform sealing along the circumference, the circular sealing protrusion 320 strengthens the sealing at specific points, and the semi-circular and rectangular cross-sections improve the sealing effect due to their good elastic deformation capacity and stable support force, respectively.

[0113] It is understood that, except for the case where both the annular sealing protrusion 310 and the circular sealing protrusion 320 are present, in some embodiments, the resilient sealing protrusion 300 may include only the annular sealing protrusion, or the resilient sealing protrusion may include only the circular sealing protrusion. Preferably, the resilient sealing protrusion 300 may include only the annular sealing protrusion.

[0114] In some embodiments, multiple resilient sealing protrusions 300 are provided. These multiple resilient sealing protrusions 300 effectively form multiple lines of sealing defense. Even if one sealing protrusion experiences slight wear or deformation due to long-term use, the other sealing protrusions can still continue to perform their sealing function, ensuring the reliability of the entire sealing mechanism 1000. It is understood that, depending on the complexity of the pipeline 2000 and its operating conditions, the width and number of the resilient sealing protrusions 300 along the axial direction of the pipeline 2000 can be increased as necessary to achieve a sealing effect where the sealing surface tightly presses against the outer wall of the pipeline 2000.

[0115] See Figure 12 In some embodiments, at least one elastic sealing protrusion 300 is provided on each side of the pipe 2000 connection. The presence of elastic sealing protrusions 300 on both sides of the pipe 2000 connection forms multiple lines of defense, increasing the difficulty of media leakage and ensuring that the media is unlikely to leak even under complex operating conditions such as high pressure. The various shapes and cross-sections of the elastic sealing protrusions 300 allow the sealing mechanism 1000 to be flexibly adjusted according to the material of the pipe 2000 and the properties of the media. Simultaneously, the arrangement of the elastic sealing protrusions 300 on both sides of the pipe 2000 connection disperses pressure, reduces the load on individual protrusions, and reduces the risk of seal failure due to excessive local pressure. Furthermore, the different shapes and cross-sections of the protrusions work together, ensuring that even if some protrusions are damaged, others can still maintain a certain sealing capacity, ensuring that the sealing mechanism 1000 can operate reliably in harsh environments or under long-term use, reducing safety accidents and economic losses caused by leakage.

[0116] See Figure 15 and Figure 16 In some embodiments, the fastener 200 includes a first fastener body 210, a second fastener body 220, and a locking member 230. The first fastener body 210 is provided with a first groove 211; the second fastener body 220 is provided with a second groove 221. The first fastener body 210 is used to fasten with the second fastener body 220. The first groove 211 and the second groove 221 surround each other to form a sealing groove 201. The locking member 230 locks and fixes the first fastener body 210 and the second fastener body 220.

[0117] With the above configuration, the fastener 200 adopts a split design, meaning the first fastener body 210 and the second fastener body 220 are separate. During installation, simply place the elastic seal 100 in the appropriate position, then fasten the first fastener body 210 and the second fastener body 220 together, and finally secure it with the locking member 230. This installation method is simpler and more convenient than the integral fastener 200, reducing installation difficulty and improving installation efficiency. In situations where space is limited at construction sites, the split fastener 200 is easier to operate. When the elastic seal 100 or the fastener 200 is damaged and needs repair or replacement, the advantages of the split design are even more pronounced. By loosening the locking member 230, the first fastener body 210 and the second fastener body 220 can be easily separated to inspect, repair, or replace the internal elastic seal 100 without dismantling the entire pipeline 2000 system, significantly shortening maintenance time and reducing maintenance costs.

[0118] See Figure 15 and Figure 16In some embodiments, two locking members 230 are provided, respectively placed on both radial sides of the pipe 2000, and the first locking body 210 and the second locking body 220 are locked and fixed on both radial sides of the pipe 2000. The locking member 230 includes a first support plate 231 and a second support plate 233. The first support plate 231 is fixed on the first locking body 210, and a first locking seat 232 is also fixedly provided on the first support plate 231. The first locking seat 232 is provided with a first locking hole 2321. The second support plate 233 is fixed on the second locking body 220, and a second locking seat 234 is also fixedly provided on the second support plate 233. The second locking seat 234 is provided with a second locking hole 2341 corresponding to the first locking hole 2321. The first locking hole 2321 and the second locking hole 2341 are connected by a locking bolt (not shown in the figure), thereby achieving a locking connection between the first locking body 210 and the second locking body 220. This presses and fixes the elastic seal 100 inside the locking member, thus sealing the connection of the pipeline 2000. During installation, simply place the elastic seal 100, engage the first locking body 210 and the second locking body 220, aligning the first locking hole 2321 and the second locking hole 2341, and then insert and tighten the locking bolt. Installation is simple. When maintaining or replacing the elastic seal 100, simply unscrew the locking bolt to separate the first locking body 210 and the second locking body 220. This convenient operation reduces maintenance time and costs, and in emergency repair situations, allows for quick problem handling, minimizing the impact of pipeline 2000 system malfunctions.

[0119] With the above setup, the first support plate 231 and the second support plate 233 are respectively fixed to the first fastening body 210 and the second fastening body 220. The first locking seat 232 and the second locking seat 234 are precisely positioned to the first locking hole 2321 and the second locking hole 2341, ensuring precise correspondence. The locking bolt passes through the two holes, making the first fastening body 210 and the second fastening body 220 fit tightly together, evenly pressing the elastic seal 100, preventing misalignment and loosening, maintaining a stable connection, and ensuring sealing performance. The stable connection of the locking element 230 ensures that the elastic seal 100 maintains the correct position and compression state during long-term use. This prevents the elastic seal 100 from shifting or deforming due to loosening of the fastening element 200, preventing seal failure, ensuring long-term reliable operation of the pipeline 2000 connection, and reducing the risk of leakage.

[0120] Furthermore, the structural design of the first locking seat 232, the second locking seat 234, the first support plate 231, and the second support plate 233 distributes the tightening force of the locking bolts onto the fastener body. This prevents excessive localized stress from damaging the fastener 200 or the elastic seal 100, extending its service life. In high-pressure pipeline 2000 connections, it can effectively withstand the internal pressure of the pipeline 2000, ensuring a stable connection.

[0121] See Figure 1In some embodiments, multiple annular reinforcing ribs 204 are provided on the outer wall of the fastener 200 to further enhance the structural strength of the fastener 200 and strengthen its sealing capability in the circumferential direction of the pipe 2000. In the circumferential direction of the pipe 200, the reinforcing ribs 204 structure can make the fastener 200 press against the elastic seal 100 more evenly.

[0122] Specifically, see 15 and Figure 16 Reinforcing hoops 204 are provided on the outer walls of the first fastening body 210 and the second fastening body 220, and the reinforcing hoops 204 on the first fastening body 210 and the reinforcing hoops 204 on the second fastening body 220 are aligned along the circumference of the pipe 2000.

[0123] In some embodiments, the sealing mechanism 1000 provided in this application may be made of materials such as silicone rubber and EPDM rubber for sealing and waterproofing, depending on the operating conditions; the sealing oil may be made of oil-resistant materials such as fluororubber and fluorosilicone rubber, and a variety of materials may be used.

[0124] The specific steps for using the sealing mechanism 1000 in this embodiment are as follows:

[0125] Align the two pipes by 2000 to ensure that their center axes are on the same straight line, and avoid misalignment that could affect the sealing performance;

[0126] Determine the installation location in advance on the outer wall of pipe 2000, and mark it if necessary. Fit the elastic seal 100 tightly against the outer wall of pipe 2000, centering it at the pipe connection point.

[0127] Then, open the dovetail groove and align the dovetail tenon that has been embedded in the metal anti-compression support 122, ensuring that the dovetail tenon and the end face of the dovetail groove are tightly fitted, thus completing the assembly of the elastic seal 100.

[0128] Install the fastener 200 onto the upper and lower sides of the elastic seal 100 so that the elastic seal 100 can be centered and filled into the sealing groove 201 of the fastener 200, preparing for subsequent sealing and fixing.

[0129] See Figure 17 The fastener 200 is secured with locking bolts, compressing and tightly filling the elastic seal 100 within the sealing groove 201 between the fastener 200 and the pipe 2000. At this point, the dovetail groove and dovetail tenon of the elastic seal 100 are locked, and the elastic seal 100 reaches the predetermined compression and filling amount. Multiple axial and radial working surfaces tightly engage with the pipe 2000 and the fastener 200, achieving a reliable seal. The specific sealing working surfaces formed are as follows:

[0130] The sealing working surfaces formed by the outer wall of the dovetail tenon and the inner wall of the dovetail groove specifically include the sealing working surfaces D1 and D2 formed by the upper and lower outer wall surfaces of the dovetail tenon and the upper and lower inner wall surfaces of the dovetail groove (see reference). Figure 18 It also includes the sealing working surface D3 formed by the dovetail tenon end face and the inner wall of the dovetail groove (see...). Figure 18 );

[0131] The sealing working surface E formed by the elastic sealing protrusion 300 and the bottom wall 2011 of the sealing groove 201 (see reference) Figure 12 );

[0132] The sealing working surface F formed by the inner wall surface of the elastic seal 100 and the outer wall surface of the pipe 2000 (see reference) Figure 12 );

[0133] The outer wall of the elastic seal 100 and the bottom wall 2011 of the sealing groove 201 form a sealing working surface G along the elongation direction (axial direction of the pipe 2000) of the pipe 2000 (see reference). Figure 12 This achieves a seal perpendicular to the 2000 mm elongation direction of the pipe;

[0134] The sealing working surfaces H and I in the elongation direction of the vertical pipe 2000 formed by the two end faces of the elastic seal 100 and the groove sidewall 2012 of the sealing groove 201 (see reference) Figure 12 This achieves a seal along the 2000-degree extension of the pipeline.

[0135] The sealing mechanism 1000 in this embodiment has the following beneficial effects:

[0136] By distributing the elastic sealing protrusions 300 on both sides of the pipe 2000 connection, after the bolts are tightened and the fasteners 200 are tightened, the elastic sealing protrusions 300 are further compressed, which can effectively fill the possible leakage channels, prevent internal and external media from leaking from the pipe 2000 connection, improve the sealing performance, and ensure the safe operation of the pipe 2000 system.

[0137] The elastic seal 100 is connected by a dovetail groove and a dovetail tenon structure, and a metal pressure-resistant support 122 is embedded in the dovetail tenon. Under the action of the fastener 200, not only is the sealing surface tightly fitted, but the deformation resistance of the dovetail groove and dovetail tenon connection is also enhanced, making the entire sealing mechanism 1000 more stable and reliable, able to withstand certain pressure and vibration, and less prone to loosening and leakage.

[0138] It reduces installation difficulty, improves installation efficiency, reduces installation time and labor costs, and is suitable for rapid installation needs in various engineering sites;

[0139] The sealing mechanism 1000 and its installation method are not limited by the size and shape of the pipe 2000. They can be adjusted and modified according to actual conditions and can be widely used in different types of pipe 2000 connections.

[0140] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0141] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
