Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline technology, specifically to a pressure-resistant plastic-lined anti-corrosion pipeline. Background Technology
[0002] Plastic-lined pipes use ordinary carbon steel pipes as the base material and are lined with thermoplastic engineering plastics with excellent chemical stability. They are formed by cold drawing or rotational molding. They have both the mechanical properties of steel pipes and the corrosion resistance, scale inhibition, and microbial growth resistance of engineering plastics. They are ideal pipes for transporting media such as acids, alkalis, salts, and corrosive gases.
[0003] Existing pipe technologies do not have adequate protection against sudden external impacts. When impact forces are applied to plastic-lined pipes, the pipes are easily compressed, causing significant deformation. Liquid impacts on the deformed and bent parts of the pipes can easily lead to pipe rupture. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a pressure-resistant plastic-lined anti-corrosion pipe, which aims to alleviate the above problems to at least a certain extent.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A pressure-resistant plastic-lined corrosion-resistant pipe, comprising:
[0007] Plastic-lined pipes;
[0008] Multiple rings are disposed outside the plastic-lined pipe;
[0009] Multiple pressure-resistant plates are disposed on the outside of the ring body, and the pressure-resistant plates are slidably disposed on the outside of the ring body;
[0010] An elastic element is provided between the compression plate and the ring body;
[0011] A connecting component is provided between every two adjacent rings to connect the two adjacent rings, and the connecting component can fix the distance and angle between every two adjacent rings.
[0012] Preferably, the elastic element comprises an arc-shaped rubber strip.
[0013] Preferably, the outer surface of the ring body is provided with multiple sliding grooves, the bottom of the pressure-resistant plate is rotatably connected to two connecting rods that are slidably connected to the sliding grooves, and the arc-shaped rubber strip is connected between the sliding grooves and the pressure-resistant plate.
[0014] Preferably, the plastic-lined pipe is fitted with a rubber sleeve, and the pressure-resistant plate is in contact with the inner wall of the rubber sleeve.
[0015] Preferably, a connecting ring is connected to one side of the ring body, and a first rod is connected to the other side of the ring body. A second rod is slidably connected inside the first rod, and a bolt is threaded onto the first rod.
[0016] Preferably, a first gear is connected inside the ring body, and one end of the second rod is connected to a second gear that meshes with the first gear.
[0017] In summary, the present invention has the following main advantages:
[0018] In application, multiple rings can be fitted over the outside of the plastic-lined pipe. Connecting components are used to link the rings together. Elastic elements between the pressure-resistant plates and the rings support the position of the pressure-resistant plates. Multiple pressure-resistant plates outside the rings support the position of the plastic-lined pipe. When external impact or sudden pressure is applied to the plastic-lined pipe, the pressure-resistant plates absorb the pressure. The pressure-resistant plates move towards the rings under force, compressing the elastic elements and buffering some of the pressure. The multiple rings and pressure-resistant plates outside the plastic-lined pipe extend its compressive strength and increase its compressive strength, thus enhancing its pressure resistance. In practical applications, multiple rings can be connected using connecting components, and the angle between each pair of adjacent rings can be adjusted appropriately. For example, if there are five pressure-resistant plates outside the rings... The angle between any two adjacent pressure-resistant plates is 72 degrees, allowing adjacent rings to rotate 36 degrees to compensate for the gaps between them. This further enhances the pressure resistance and prevents significant deformation of the lined pipe caused by external impacts. Furthermore, the distance between each pair of rings can be determined and fixed using connecting components. For example, if a section of the lined pipe is buried under a highway surface, the distance between the two rings can be appropriately shortened, providing more comprehensive protection for the lined pipe. Compared to existing lined anti-corrosion pipes, this application solves the problem of inadequate protection against sudden external impacts. When impacts are applied to the lined pipe, it is easily compressed, causing significant deformation, and liquid impacts can easily lead to pipe rupture due to the bent sections.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] refer to Figures 1-4 A pressure-resistant plastic-lined anti-corrosion pipe, comprising:
[0029] 100mm plastic-lined pipe;
[0030] Multiple rings 101 are provided outside the plastic-lined pipe 100;
[0031] Multiple pressure-resistant plates 102 are disposed outside the ring body 101, and the pressure-resistant plates 102 are slidably disposed outside the ring body 101;
[0032] An elastic element 103 is provided between the compression plate 102 and the ring 101;
[0033] A connecting component is provided between every two adjacent ring bodies 101 to connect the two adjacent ring bodies 101. The connecting component can fix the distance and angle between every two adjacent ring bodies 101.
[0034] During application, multiple rings 101 can be fitted onto the outside of the plastic-lined pipe 100 by operators using connecting components. The elastic element 103 between the pressure-resistant plate 102 and the rings 101 supports the position of the pressure-resistant plate 102. The multiple pressure-resistant plates 102 outside the rings 101 support the position of the plastic-lined pipe 100. When external impact or sudden pressure is about to be applied to the plastic-lined pipe 100, the pressure-resistant plates 103 provide support. 2. Under pressure, the pressure-resistant plate 102 moves towards the ring 101, causing the elastic element 103 to compress and buffer part of the pressure. The multiple rings 101 and the multiple pressure-resistant plates 102 arranged outside the plastic-lined pipe 100 can extend the pressure-resistant length of the plastic-lined pipe 100 and increase the pressure-resistant direction, thereby increasing the pressure resistance of the plastic-lined pipe 100. In specific applications, the multiple rings 101 can be connected using connecting parts, and the positions of every two adjacent rings 101 can be adjusted appropriately. The angle between the rings, such as the five pressure-resistant plates 102 outside the ring 101, is 72 degrees between any two adjacent pressure-resistant plates 102. This allows the adjacent rings 101 to rotate 36 degrees to fill the gap between each pair of rings 101, further improving the pressure resistance and preventing external impact forces from causing significant deformation of the lined pipe 100. Simultaneously, the distance between each pair of rings 101 can be determined and fixed using connecting components. For example, if a section of the lined pipe 100 is buried under a highway surface, the distance between the two rings 101 can be appropriately shortened, providing more comprehensive protection for the lined pipe 100. Compared to existing lined anti-corrosion pipes, this application solves the problem of insufficient protection against sudden external impacts. When impact forces are applied to the lined pipe 100, the pipe is easily compressed, causing significant deformation, and liquid impacts can easily cause the deformed and bent parts of the pipe to rupture.
[0035] As a further feature of this invention, the elastic element 103 includes an arc-shaped rubber strip 104;
[0036] By setting the arc-shaped rubber strip 104, when the impact force is applied to the pressure-resistant plate 102, the arc-shaped rubber strip 104 will undergo compression deformation. When the impact force disappears, the arc-shaped rubber strip 104 can be reset by its own elastic properties, thereby achieving the purpose of buffering the impact force and pressure.
[0037] As a further feature of this invention, the outer surface of the ring 101 is provided with a plurality of sliding grooves 200, and the bottom of the pressure plate 102 is rotatably connected to two connecting rods 201 that are slidably connected to the sliding grooves 200. An arc-shaped rubber strip 104 is connected between the sliding grooves 200 and the pressure plate 102.
[0038] By setting the connecting rod 201, the connecting rod 201 can support and limit the position of the pressure plate 102. When the impact force is applied to the pressure plate 102, the pressure plate 102 moves towards the ring 101, and the bottom of the connecting rod 201 slides in the slide groove 200. The friction between the connecting rod 201 and the slide groove 200 can also buffer part of the impact force. When the arc rubber strip 104 returns to its original position after bending, the friction between the connecting rod 201 and the slide groove 200 can also counteract its rebound force.
[0039] As a further aspect of this utility model, a rubber sleeve 202 is provided on the outside of the plastic-lined pipe 100, and the pressure-resistant plate 102 is in contact with the inner wall of the rubber sleeve 202.
[0040] By installing a rubber sleeve 202, when the plastic-lined pipe 100 and the ring 101 are buried underground, a rubber sleeve 202 can be installed on the outside of the plastic-lined pipe sleeve, which can prevent moisture from underground from penetrating the ring 101 and the connecting rod 201 and causing the connecting rod 201 to slide poorly.
[0041] As a further part of this utility model, a connecting ring 300 is connected to one side of the ring body 101, a first rod 301 is connected to the other side of the ring body 101, a second rod 302 is slidably connected inside the first rod 301, and a bolt 303 is threadedly connected to the first rod 301.
[0042] By setting a connecting ring 300, after two or more ring bodies 101 are fitted onto the plastic-lined pipe 100, the second rod 302 is inserted into the connecting ring 300 on another ring body 101. The second rod 302 can slide within the connecting ring 300. After adjusting the angle of the ring body 101, the second rod 302 can be fastened to the first rod 301 by the tightening force of the bolt 303, thereby achieving the purpose of fixing the distance between the two ring bodies 101.
[0043] As a further part of this utility model, a first gear 304 is connected inside a pressure-resistant plastic-lined anti-corrosion pipe ring 101, and a second gear 305 that meshes with the first gear 304 is connected to one end of a second rod 302.
[0044] By setting the second gear 305, when adjusting the angle of the ring 101, rotating the angle of one of the rings 101 causes the second gear 305 and the second rod 302 to rotate within the first rod 301. After securing the position of the second rod 302 with the bolt 303, it can be ensured that the second rod 302 will not rotate. The meshing force of the first gear 304 and the second gear 305 can ensure that the angles of the two rings 101 are fixed and will not cause the rings 101 to rotate due to impact.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
