Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pressure-resistant socket pipe device and a pipe device. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, pipelines, as important carriers for transporting fluid media, directly affect the safety and efficiency of engineering projects in terms of performance and reliability. However, traditional pipeline systems often exhibit problems such as insufficient pressure resistance, easy leakage at connections, and high maintenance costs when faced with complex geological conditions, high-pressure environments, and long-term operational wear.

[0003] In existing technologies, piping systems typically consist of a pipe body and connecting components, connected via sockets, flanges, or welding. Engineering practice shows that over 70% of leaks in existing piping systems occur at the junction of the pipe connection and the pipe body. These traditional connection methods, when subjected to external pressure, lead to deformation or rupture at the joint. Because the structural design of joints and connections has not been optimized, these areas are prone to stress concentration under external pressure. This stress concentration causes localized stress to far exceed the average stress, and the joints are relatively weak, making them susceptible to breakage. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to address the issue of poor pressure-bearing capacity at the connection point of existing socket pipe devices.

[0005] To solve the above-mentioned technical problems, this utility model provides a pressure-resistant socket pipe device, characterized in that the pressure-resistant socket pipe device includes:

[0006] A plug connector, comprising a pipe connection portion and a plug portion, wherein the pipe connection portion is located at one end of the plug connector and the plug portion is located at the other end of the plug connector;

[0007] A socket joint, comprising a pipe connection part and a receiving part, wherein the pipe connection part is located at one end of the socket joint and the receiving part is located at the other end of the socket joint, and when the spigot joint is inserted into the socket joint, the outer wall of the spigot part is engaged with the outer wall of the receiving part;

[0008] The pipe body is connected to the pipe connection part, and the outer diameter of the pipe body is smaller than the outer diameter of the pipe connection part;

[0009] A pressure-resistant component is disposed on the outer wall of the pipe body. The pressure-resistant component is wedge-shaped and includes a bottom surface, a side end surface, and a slope surface. The bottom surface of the pressure-resistant component is fitted and connected to the outer wall of the pipe body, the side end surface is fitted and connected to the side wall of the pipe connection part, one end of the slope surface is connected to the side wall of the pipe connection part, and the other end of the slope surface is connected to the outer wall of the pipe body.

[0010] Furthermore, multiple pressure-resistant components are provided, and the multiple pressure-resistant components are circumferentially arranged on the outer wall of the pipe body, with the bottom surface of at least one pressure-resistant component located at the highest radial point of the pipe body.

[0011] Furthermore, the plurality of pressure-resistant components are of the same size, and the distance between adjacent pressure-resistant components is equal.

[0012] Furthermore, the pressure-resistant component is equipped with a pressure detection module, and the slope surface is equipped with a pressure sensor. The pressure sensor is used to transmit the pressure signal received by the slope surface to the pressure detection module, and the pressure detection module transmits the received signal to the enterprise monitoring terminal.

[0013] Furthermore, the bonding connection includes welding.

[0014] Furthermore, the inner wall of the pipe connection is flush with the inner wall of the pipe body.

[0015] Furthermore, a metal layer is provided between the inner wall of the pipe body and the outer wall of the pipe body.

[0016] Furthermore, the metal layer comprises a first metal layer and a second metal layer arranged radially in sequence, wherein the first metal layer and the second metal layer are interconnected to form a sealed cavity.

[0017] Furthermore, a spring is installed inside the cavity.

[0018] Compared with the prior art, the advantages of this pressure-resistant socket pipe device are as follows:

[0019] This invention features a wedge-shaped pressure-resistant component on the outer wall of the pipe body. The bottom surface of this component is in close contact with the outer wall of the pipe body. The sloped surface of the pressure-resistant component evenly disperses the stress generated when the pipe is subjected to external pressure, while the side end face is in close contact with the pipe connection, enhancing the stability of both the pipe connection and the pipe body. When the pipe body is subjected to external pressure, the pressure-resistant component disperses the pressure over a larger area, preventing localized stress concentration and effectively improving the pressure-bearing capacity of the connection. This is particularly useful in scenarios where the pipe is buried in quicksand, where the pressure distribution is often uneven, with varying magnitudes and directions at different locations. The pressure-resistant component guides the pressure from the weaker connection area through the gravity of the quicksand and the wedge shape, diverting the pressure to the more pressure-resistant pipe body, thus enhancing the pressure-bearing capacity of the socketed pipe assembly at the connection. The pressure-resistant component disperses pressure from the connection between the pipe body and the pipe connection to other areas, protecting the most vulnerable part of the pipe, enhancing the stability of the connection, and achieving a pressure-resistant effect.

It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical values ​​of the components and steps described in these examples do not limit the scope of this utility model.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0030] like Figure 1-3 As shown, this utility model embodiment provides a pressure-resistant socket pipe device, the pressure-resistant socket pipe device comprising:

[0031] The socket connector 200 includes a pipe connection portion 220 and a plug portion 210. The pipe connection portion 220 is located at one end of the socket connector 200, and the plug portion 210 is located at the other end of the socket connector 200.

[0032] The socket joint 300 includes a pipe connection part 220 and a receiving part 310. The pipe connection part 220 is located at one end of the socket joint 300, and the receiving part 310 is located at the other end of the socket joint 300. When the spigot joint 200 is inserted into the socket joint 300, the outer wall of the spigot part 210 is engaged with the outer wall of the receiving part 310.

[0033] The pipe body 100 is connected to the pipe connection part 220, and the outer diameter of the pipe body 100 is smaller than the outer diameter of the pipe connection part 220.

[0034] A pressure-resistant component 110 is disposed on the outer wall of the pipe body 100. The pressure-resistant component 110 is wedge-shaped and includes a bottom surface 111, a side end surface 112, and a slope surface 113. The bottom surface 111 is fitted and connected to the outer wall of the pipe body 100, the side end surface 112 is fitted and connected to the side wall of the pipe connection part 220, one end of the slope surface 113 is connected to the side wall of the pipe connection part 220, and the other end of the slope surface 113 is connected to the outer wall of the pipe body 100.

[0035] The pipeline body 100 is the main structure for fluid transport, responsible for conveying fluid from one end to the other. The pressure-resistant component 110 is wedge-shaped and consists of a bottom surface 111, a side end surface 112, and a slope surface 113. The bottom surface 111 of the pressure-resistant component is completely fitted to the outer wall of the pipeline body 100, the side end surface 112 is tightly connected to the side wall of the pipeline connection 220, and the slope surface 113 forms a pressure transmission transition zone. When the pipeline is subjected to external pressure, the wedge-shaped structure transforms concentrated stress into dispersed force along the pipeline axis through the slope surface 113. For example, in quicksand geology, the non-uniform pressure of quicksand on the pipeline connection can be guided to the pipeline body 100 through the wedge-shaped slope, preventing failure of the connection between the pipeline body 100 and the pipeline connection 220 due to stress concentration. The outer wall of the insertion part 210 of the plug connector 200 and the outer wall of the receiving part 310 of the socket connector 300 are mechanically snapped together, which improves the pull-out resistance compared with traditional adhesive bonding or single bolt connection. A sealing ring can be set between the receiving part 310 and the insertion part 210 to enhance the waterproof function.

[0036] This invention features a wedge-shaped pressure-resistant component 110 on the outer wall of the pipe body 100, with its bottom surface fitting snugly against the outer wall of the pipe body 100. The slope surface 113 of the pressure-resistant component 110 can evenly disperse the stress generated by the pipe when subjected to external pressure, while the side end face 112 fits snugly against the pipe connection part 220, which can enhance the stability of the pipe connection part 220 and the pipe body 100. When the pipe body 100 is subjected to external pressure, the pressure-resistant component 110 can disperse the pressure over a larger area, avoiding local stress concentration, thereby effectively improving the pressure-bearing capacity of the connection. Especially in the scenario where the pipe is buried in quicksand, the pressure distribution in quicksand is often uneven, with different pressure magnitudes and directions at different locations. The pressure-resistant component 110 can guide the pressure of the connection part with poor pressure-bearing capacity through the gravity of the quicksand and the wedge-shaped pressure-resistant component 110, distributing the pressure of the quicksand to the pipe body 100 part with strong pressure-bearing capacity, thereby enhancing the pressure-bearing capacity of the socket pipe device at the connection. The pressure-resistant component 110 disperses the pressure from the connection between the pipe body 100 and the pipe connection 220 to other places, protecting the most vulnerable part of the pipe, enhancing the stability of the connection, and achieving the effect of pressure resistance.

[0037] like Figure 4 As shown, in an optional embodiment of the present invention, a plurality of pressure-resistant members 110 are provided, and the plurality of pressure-resistant members 110 are circumferentially arranged on the outer wall of the pipe body 100, and the bottom surface 111 of at least one pressure-resistant member is located at the highest point of the radial direction of the pipe body 100.

[0038] Specifically, multiple pressure-resistant components 110 are provided, circumferentially arranged on the outer wall of the pipe body 100, forming an effective support structure. At least one pressure-resistant component has its bottom surface 111 positioned at the highest radial point of the pipe body 100. This design maximizes the use of the pressure-resistant components 110 to distribute and withstand external pressure. The circumferential arrangement of multiple pressure-resistant components 110 ensures uniform support for the pipe body 100 in all directions, effectively preventing pipe deformation or damage caused by pressure concentration. Simultaneously, the pressure-resistant component 110 located at the highest radial point can directly withstand vertical pressure, such as the weight of the backfill soil. Through its curved bottom surface's close contact with the pipe body 100, the vertical pressure is converted into circumferential stress, further dispersing it throughout the entire pipe body 100 and enhancing the overall pressure resistance of the pipe. This design not only improves the stability of the pipeline under complex geological conditions but also significantly extends its service life.

[0039] In an optional embodiment of this utility model, the plurality of pressure-resistant members 110 are of the same size, and the distance between adjacent pressure-resistant members 110 is equal.

[0040] Specifically, the pressure-resistant components 110 form a ring-shaped support network with equal arc length intervals. Each pressure-resistant component 110 serves as a discrete support point, and their periodic arrangement constructs an equivalent continuous support ring. This layout creates uniform mechanical boundary conditions in the circumferential direction of the pipeline, avoiding local stress concentration caused by uneven support. In quicksand geology, non-uniform pressure is transformed into regular circumferential stress waves through the periodic support network. The pressure transmission phase difference is consistent, preventing local stress superposition caused by pressure wave interference. The slope surface 113 of the pressure-resistant components 110 decomposes the vertical pressure into axial and circumferential components. The equidistant arrangement allows the component forces to form a closed-loop transmission path in the circumference of the pipeline, improving the pressure dispersion efficiency compared to a non-uniform arrangement.

[0041] In an optional embodiment of this utility model, a pressure detection module is provided inside the pressure-resistant component 110, and a pressure sensor is provided on the slope surface 113. The pressure sensor is used to transmit the pressure signal received by the slope surface 113 to the pressure detection module, and the pressure detection module transmits the received signal to the enterprise monitoring terminal.

[0042] Specifically, the pressure-resistant component 110 has a pre-reserved standardized mounting slot for embedding a miniature pressure detection module. This module uses MEMS technology to ensure seamless integration with the pressure-resistant component 110. The module includes a signal conditioning circuit, an A / D converter, and a wireless communication unit, enabling on-site digital processing of pressure signals. The pressure sensor is precisely mounted in the central area of ​​the slope surface 113, which is the core area of ​​stress concentration at the connection. The pressure signal can be transmitted to gateways deployed along the pipeline via Bluetooth Low Energy protocol, meeting the coverage requirements of suburban pipeline networks. After edge computing processing, the gateway data is uploaded to the enterprise monitoring cloud platform via 4G / 5G networks.

[0043] In this embodiment of the invention, by setting a pressure sensor and integrating sensing technology, communication technology and data analysis technology, the real-time perception and intelligent management of the health status of the pipeline connection is realized.

[0044] In an optional embodiment of the present invention, the metal layer includes a first metal layer and a second metal layer arranged radially in sequence, wherein the first metal layer and the second metal layer are interconnected to form a sealed cavity.

[0045] The metal layer consists of a first metal layer and a second metal layer arranged radially. These two layers are precision welded to form a robust support structure. The cavity can be filled with inert gas or evacuated to create a highly efficient thermal insulation barrier. The sealed cavity effectively blocks heat conduction, significantly reducing heat loss in high or low temperature conditions and improving energy efficiency. As an energy absorption layer, the cavity structure effectively buffers external impacts, reducing the risk of pipeline deformation under complex conditions and enhancing pipeline safety. The cavity structure effectively blocks the propagation path of sound waves, thereby reducing the transmission of sound waves generated by fluid flow or external noise, providing sound insulation and noise reduction. Compared to a solid metal layer, the cavity structure significantly reduces material usage while maintaining sufficient structural strength, thus reducing the overall weight of the pipeline and helping to lower transportation and installation costs. As a barrier, the cavity structure prevents corrosive media from directly contacting the pipeline body, thereby extending the pipeline's service life.

[0046] The elastic properties of the spring allow the cavity to deform and absorb energy when subjected to external impact or pressure, thereby reducing the risk of deformation and damage to the pipeline body 100. This buffering effect is particularly important when the pipeline may be subjected to accidental impacts during transportation, installation, or operation. The addition of the spring provides additional expansion or contraction space for the metal layer when temperature changes. When the pipeline expands or contracts due to temperature changes, the spring can compensate for this change through its deformation, further reducing the impact of thermal stress on the pipeline and maintaining its structural stability. The placement of the spring within the cavity enhances the stability of the entire structure. Under complex stress conditions, such as when the pipeline is subjected to bending, torsion, or vibration, the spring can provide additional support and damping, reducing the deformation and vibration amplitude of the pipeline and improving its safety. The presence of the spring facilitates the integration of other functional modules within the cavity. For example, sensors, communication lines, etc., can be arranged in the spring gaps to achieve real-time monitoring and intelligent management of the pipeline's operating status. This multi-functional integrated design helps to improve the intelligence level of pipeline devices and meet the needs of modern industry for efficient and intelligent pipeline systems.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
