Description

Technical Field

[0001] This utility model relates to the field of PE gas pipe technology, and in particular to a shock-resistant and reinforced PE gas pipe. Background Technology

[0002] PE pipe, also known as polyethylene pipe, is a type of plastic pipe characterized by its corrosion resistance, impact resistance, and long service life. It is primarily used for water supply and gas pipelines. When PE pipe is used as a gas pipeline, it requires a higher level of safety compared to water pipes to prevent gas leaks.

[0003] When PE pipes are used as gas pipes, they are generally laid underground or fixed along the surface of buildings. When natural disasters such as earthquakes occur, geological movements can cause tensile forces in multiple directions on the gas pipes, leading to problems such as pipe breakage and damage.

[0004] To address these issues, gas pipes need a certain degree of flexibility to sway with the pulling force of vibrations and avoid damage from excessive stress. However, excessive flexibility weakens the internal pressure resistance of gas pipes and makes them susceptible to deformation under external pressure during installation, potentially preventing normal gas delivery. Consequently, existing PE gas pipes cannot simultaneously meet both deformation resistance and seismic resistance requirements.

[0005] Therefore, this application proposes a seismically reinforced PE gas pipe, which enables the PE gas pipe to have both seismic resistance and deformation resistance. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a shock-resistant reinforced PE gas pipe to solve the problem that the existing PE gas pipe cannot simultaneously achieve both deformation resistance and shock resistance.

[0007] To achieve the above and other related objectives, this utility model provides a shock-resistant and reinforced PE gas pipe, including an inner pipe, wherein a plurality of partition ribs are arranged in an equidistant circumferential array on the outer surface of the inner pipe, and an outer protective pipe is provided on the outer surface of the partition ribs to cover the inner pipe and the partition ribs;

[0008] The inner tube, the dividing strip, and the outer protective tube are all of equal length;

[0009] The inner tube wall is embedded with a plurality of reinforcing ribs arranged in an equidistant circular array with the inner tube axis as the axis. When the reinforcing ribs are subjected to a threshold force, they can bend or break, making the inner tube bendable.

[0010] Preferably, the reinforcing rib includes a metal rod, and the outer surface of the metal rod is provided with a plurality of fracture grooves at equal intervals.

[0011] Preferably, the cross-section of the fracture groove is inverted U-shaped, and the depth of the fracture groove is half the diameter of the metal rod.

[0012] Preferably, the cross-section of the dividing rib is an isosceles trapezoid, and the cross-section of the dividing rib on the side closer to the inner tube is larger than the cross-section on the side closer to the outer protective tube.

[0013] Preferably, an isolation hole is provided between two adjacent dividing strips.

[0014] Preferably, a reinforcing mesh is provided between the inner tube and the outer protective tube, and the length of the reinforcing mesh is equal to that of the inner tube.

[0015] Preferably, the reinforcing mesh is a cylindrical metal mesh, and the inner and outer walls of the reinforcing mesh have gaps between the outer surface of the inner tube and the inner wall of the outer protective tube, respectively.

[0016] Preferably, the reinforcing mesh extends through all the dividing ribs, and the reinforcing mesh is limited by the dividing ribs.

[0017] Preferably, the mesh openings in the reinforcing mesh are smaller than the spacing between the isolation holes.

[0018] As described above, the shock-resistant reinforced PE gas pipe of this utility model has the following beneficial effects:

[0019] 1. This utility model provides several reinforcing ribs on the inner wall of the inner tube. The reinforcing ribs support the inner tube to maintain its shape and improve its compressive strength. When the vibration force applies excessive tensile force to the inner tube, the reinforcing ribs will bend or break at the stress point, thereby restoring the inner tube's flexibility and achieving the effect of both deformation resistance and seismic resistance.

[0020] 2. This utility model improves the impact resistance and puncture resistance of the entire pipeline by setting a dividing rib on the outer surface of the inner tube and setting an outer protective tube on the outer surface of the dividing rib. The outer protective tube covers the inner tube and the dividing rib respectively, and an isolation hole is set between two adjacent dividing ribs. The outer protective tube and the isolation hole improve the impact resistance and puncture resistance of the entire pipeline, thereby improving the safety.

[0021] 3. This utility model increases the overall pipeline's resistance to external pressure by setting a reinforcing mesh between the inner pipe and the outer protective pipe. At the same time, when a foreign object pierces the outer protective pipe, the reinforcing mesh can block the foreign object to prevent it from continuing to pierce the inner pipe, thus further improving safety.

[0022] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0031] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0032] like Figures 1-2As shown, this utility model provides a shock-resistant reinforced PE gas pipe, including an inner pipe 1 through which gas is transmitted. A plurality of equidistant circumferential dividing ribs 2 are arranged on the outer surface of the inner pipe 1. These dividing ribs 2 reinforce the structure of the inner pipe 1, making it less prone to bending and deformation. An outer protective pipe 3 covers the inner pipe 1 and the dividing ribs 2, forming an outer protective armor. When the inner pipe 1 is pre-embedded, sharp objects such as stones in the soil can be effectively prevented from directly contacting the surface of the inner pipe 1 and piercing it under soil pressure, thus improving the safety of the gas pipeline. The inner pipe 1, dividing ribs 2, and outer protective pipe 3 are all made of PE material, giving them a certain degree of flexibility. The inner pipe 1, dividing ribs 2, and outer protective pipe 3 are all of equal length, allowing them to provide complete protection for the inner pipe 1.

[0033] The inner tube 1 has multiple reinforcing ribs 5 embedded in its inner wall, arranged in a circular array at equal intervals around its axis. These ribs support the shape of the inner tube 1, preventing excessive collapse when subjected to external pressure. They also provide good bending resistance, facilitating pipe installation. When subjected to forces such as earthquakes that cause severe tensile or torsional stress on the inner tube 1, the reinforcing ribs 5 can bend or break after reaching a threshold force, restoring the inner tube 1's flexibility. This allows the inner tube 1 to bend and release stress due to tensile or torsional forces, reducing the risk of breakage or damage due to excessive rigidity.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments, the reinforcing rib 5 of this invention includes a metal rod 51. The outer surface of the metal rod 51 is provided with a plurality of fracture grooves 52 at equal intervals, making the fracture grooves 52 the bending and breaking points of the metal rod 51. Under normal circumstances, the metal rod 51 is a single unit used to support the inner tube 1, improving its resistance to pressure and bending. When the force on the inner tube 1 exceeds the strength of the connection between the fracture grooves 52, the metal rod 51 preferably bends along the fracture grooves 52 until it breaks at the fracture groove 52 where the force is applied, losing support for the inner tube 1. This allows the inner tube 1 to bend and twist in the direction of the applied force from the break point of the metal rod 51, thereby relieving or reducing the force exerted on the inner tube 1 and making it less prone to breakage or damage.

[0035] like Figure 5As shown, in some embodiments, the cross-section of the fracture groove 52 of this invention is an inverted U-shape. When the fracture groove 52 breaks due to external force, the cross-section at the U-shaped break is smoother than the V-shaped cross-section, making it less likely to cause puncture damage to the inner tube 1. The depth of the fracture groove 52 is half the diameter of the metal rod 51. This allows the metal rod 51 to support the inner tube 1 while breaking under external force.

[0036] If the fracture groove 52 is too shallow, the metal rod 51 will require a large external force to break, preventing the inner tube 1 from bending and releasing stress in a timely manner. Conversely, if the groove is too deep, the metal rod 51 may break under slight external force, failing to provide effective support for the inner tube 1.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the cross-section of the dividing rib 2 of this invention is an isosceles trapezoid. An isosceles trapezoid has good resistance to deformation, thereby improving the bending resistance of the inner tube 1 and making the inner tube 1 less prone to bending. The cross-section of the dividing rib 2 on the side closer to the inner tube 1 is larger than the cross-section on the side closer to the outer protective tube 3. When the outer wall of the outer protective tube 3 is subjected to pressure, the pressure will be transmitted to the outer surface of the inner tube 1 through the larger cross-section of the dividing rib 2, thereby reducing the stress on the outer surface of the inner tube 1.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, an isolation hole 4 is provided between two adjacent separating ribs 2 of this utility model. The isolation hole 4 is a force buffer. When the outer surface of the outer protective tube 3 is subjected to an impact force, the impact force will be buffered by the isolation hole 4 and then transmitted to the surface of the inner tube 1, further improving the safety of the inner tube 1.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments, a reinforcing mesh 6 is provided between the inner tube 1 and the outer protective tube 3 of this utility model, and the length of the reinforcing mesh 6 is equal to that of the inner tube 1. The reinforcing mesh 6 is used to increase the overall deformation resistance of the pipeline. At the same time, when the inner tube 1 is subjected to piercing force, the reinforcing mesh 6 can effectively block the piercing object and prevent the piercing object from continuing to pierce the inner tube 1.

[0040] like Figure 2 and Figure 3 As shown, in some embodiments, the reinforcing mesh 6 of this invention is a cylindrical metal mesh used to fully cover the outer surface of the inner tube 1, improving the inner tube 1's resistance to deformation and puncture. Gaps are left between the inner and outer walls of the reinforcing mesh 6 at the outer surface of the inner tube 1 and the inner wall of the outer protective tube 3, respectively, allowing the reinforcing mesh 6 to deform. When the entire pipeline is under stress, the force is buffered by the deformation of the reinforcing mesh 6, thus improving the pipeline's safety.

[0041] like Figure 2 As shown, in some embodiments, the reinforcing mesh 6 of this invention penetrates all the dividing ribs 2, thereby making all the dividing ribs 2 a whole. When resisting bending, all the dividing ribs 2 can jointly resist external forces, improving the anti-deformation effect. Moreover, the reinforcing mesh 6 is limited by the dividing ribs 2, preventing the reinforcing mesh 6 from twisting or displacing when subjected to torsional forces.

[0042] like Figure 2 As shown, in some embodiments, the mesh openings in the reinforcing mesh 6 of this invention are smaller than the spacing of the isolation holes 4. When a foreign object pierces the inner tube 1 and enters the isolation hole 4, the reinforcing mesh 6 can prevent the piercing object from contacting the inner tube 1 through the smaller mesh openings, thereby improving the protective performance of the reinforcing mesh 6.

[0043] In summary, the earthquake-resistant reinforced PE gas pipe of this utility model, by setting several reinforcing ribs 5 on the inner wall of the inner pipe 1, can fully support the inner pipe 1 to maintain its shape and improve the compressive strength of the inner pipe 1. When the vibration force applies excessive tensile force to the inner pipe 1, the reinforcing ribs 5 will break from the stress point, thereby restoring the inner pipe 1 to its bendability, achieving the effect of both deformation resistance and earthquake resistance.

[0044] This utility model improves the impact resistance and puncture resistance of the entire pipeline by setting a dividing rib 2 on the outer surface of the inner tube 1 and an outer protective tube 3 on the outer surface of the dividing rib 2. The outer protective tube 3 covers the inner tube 1 and the dividing rib 2 respectively, and an isolation hole 4 is set between two adjacent dividing rib 2. The outer protective tube 3 and the isolation hole 4 enhance the safety of the pipeline.

[0045] This utility model further increases the overall pipeline's resistance to external pressure by setting a reinforcing mesh 6 between the inner pipe 1 and the outer protective pipe 3. At the same time, when a foreign object pierces the outer protective pipe 3, the reinforcing mesh 6 can block the foreign object to prevent it from continuing to pierce the inner pipe 1, thus achieving a further improvement in safety.

[0046] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
