Description

Technical Field

[0001] This utility model relates to the field of rigid pipe manufacturing technology of vinyl chloride polymer, specifically, to a high-pressure resistant rigid pipe made of vinyl chloride polymer. Background Technology

[0002] Vinyl chloride polymer rigid pipes are made from amorphous thermoplastic resin produced by free radical polymerization of vinyl chloride monomer (VCM), with the addition of appropriate additives (such as stabilizers, lubricants, and fillers). This material has high mechanical strength and corrosion resistance, and is widely used in various fields such as industry, construction, and transportation. The market for vinyl chloride polymer rigid pipes has shown a steady growth trend in recent years, and its size continues to expand with rapid economic development and increasing demand from various industries.

[0003] When transporting media using rigid vinyl chloride polymer (PVC) pipes, a high-pressure resistant structure is added to the original PVC pipes to increase their service life. This high-pressure resistant structure thickens the pipe wall, increasing the overall weight of the pipeline. This leads to increased difficulty and cost in transportation and installation, and the increased weight may also affect the mobility and ease of operation of the equipment. During transportation and use, the outer wall of the PVC pipe is subject to friction damage, necessitating the addition of a protective structure to the outer end of the PVC pipe, further increasing transportation costs. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a high-pressure resistant polyvinyl chloride polymer rigid pipe, which solves the problem that the original high-pressure resistant structure thickens the pipe wall, resulting in an increase in the overall weight of the pipe, which increases the difficulty and cost of transportation and installation. The increased weight may also affect the mobility and ease of operation of the equipment. During the transportation and use of the polyvinyl chloride polymer rigid pipe, the outer wall of the polyvinyl chloride polymer rigid pipe is damaged by friction, which requires the subsequent addition of a protective structure to the outer end of the polyvinyl chloride polymer rigid pipe, resulting in increased transportation costs.

[0005] According to one aspect, at least one embodiment of the present invention provides a high-pressure resistant polyvinyl chloride polymer rigid pipe, comprising: a reinforcing layer, wherein a first stabilizing block is fixedly installed on the outer wall of the reinforcing layer, and a second stabilizing block is fixedly installed on the right side of the first stabilizing block;

[0006] A first thickened layer is fixedly installed on the outer end of a second stabilizing block, and a first support block is fixedly installed on the outer side of the first thickened layer. A first fixing ring is fixedly installed on the outer end of the first support block. A second thickened layer is fixedly connected to the right side of the first fixing ring, and a second support block is fixedly installed on the outer side of the second thickened layer. A second fixing ring is fixedly installed on the outer side of the second support block. A third thickened layer is fixedly connected to the right side of the second fixing ring, and a third support block is fixedly installed on the outer side of the third thickened layer. A third fixing ring is fixedly installed on the outer side of the third support block.

[0007] For example, in at least one embodiment of the present invention, a high-pressure resistant vinyl chloride polymer rigid pipe is provided, which further includes: an outer rigid pipe fixedly installed at the outer end of the reinforcing layer, an inner rigid pipe fixedly installed inside the outer rigid pipe, an installation interlayer fixedly opened on the outer side of the inner rigid pipe, and a transport space fixedly opened inside the inner rigid pipe.

[0008] For example, in at least one embodiment of the present invention, a high-pressure resistant vinyl chloride polymer rigid pipe is provided, which further includes: a corrosion-resistant layer fixedly installed inside the transport space; an anti-aging layer fixedly installed on the outside of the outer rigid pipe; a substrate layer fixedly installed at the outer end of the anti-aging layer; a wear-resistant layer fixedly installed at the outer end of the substrate layer; a protective sleeve fixedly connected to the outer end of the wear-resistant layer; and a reinforcing rib fixedly installed at the outer end of the protective sleeve.

[0009] For example, in at least one embodiment of the present invention, a high-pressure resistant vinyl chloride polymer rigid pipe is provided, which further includes: the reinforcing layer and the mounting interlayer are fixedly installed, the first stabilizing block and the second stabilizing block have the same structure, and the interior of the first stabilizing block is a hollow structure.

[0010] For example, in at least one embodiment of the present invention, a high-pressure resistant polyvinyl chloride polymer rigid pipe is provided, which further includes: the first stabilizing block has a six-group structure, and each group has three blocks; the inner wall of the first thickened layer and the reinforcing layer are fixedly connected; the first support block, the second support block and the third support block have the same structure; the first support block is triangular in shape; and the first fixing ring, the second fixing ring and the third fixing ring have the same structure.

[0011] For example, in at least one embodiment of the present invention, a high-pressure resistant polyvinyl chloride polymer rigid pipe is provided, which further includes: the first fixing ring and the second fixing ring are symmetrically installed on the left and right sides of the first stabilizing block with the first stabilizing block as the central reference, and the second fixing ring and the third fixing ring are symmetrically installed on the left and right sides of the second stabilizing block with the second stabilizing block as the central reference.

[0012] For example, in at least one embodiment of the present invention, a high-pressure resistant vinyl chloride polymer rigid tube is provided, which further includes: the outer rigid tube and the inner rigid tube have the same structure, and the inner wall of the outer rigid tube and the upper surface of the first fixing ring are connected in a close fit.

[0013] For example, in at least one embodiment of the present invention, a high-pressure resistant vinyl chloride polymer rigid pipe is provided, which further includes: the protective sleeve is a detachable structure, and the protective sleeve is connected to the outer rigid pipe through a wear-resistant layer, and the number of reinforcing ribs is five.

[0014] The beneficial effects of the embodiments of this utility model are as follows:

[0015] In this invention, a stabilizing block is installed at the upper end of the reinforcing layer. The stabilizing block has a hexagonal hollow structure. Multiple stabilizing blocks are used to support the inside of the rigid pipe, reducing the overall weight of the rigid pipe and facilitating subsequent transportation. Thickened layers are added to both sides of the stabilizing block, and the support blocks are installed in the thickened layers. The thickened layers are supported by triangular support blocks, which increase the overall stability between the thickened layers and the fixing ring. The above configuration imitates the internode structure of bamboo, increasing the local wall thickness inside the pipe body, reducing the overall weight while increasing the compressive strength. In addition, in this device, the rigid pipe adopts a material gradient change from the inside to the outside. The inner layer uses high corrosion-resistant CPVC, the middle reinforcing layer, and the outer anti-aging layer to increase the performance of the rigid pipe. A protective sleeve is installed at the outer end of the rigid pipe. The protective sleeve is made of recyclable material to protect the rigid pipe during transportation. The above configuration improves the internal performance of the rigid pipe and increases its service life. Attached Figure Description

[0028] like Figures 1-3 As shown, it illustrates a high-pressure resistant polyvinyl chloride polymer rigid pipe according to an embodiment of the present invention, comprising: a reinforcing layer 5, a first stabilizing block 6 fixedly installed on the outer wall of the reinforcing layer 5, and a second stabilizing block 7 fixedly installed on the right side of the first stabilizing block 6;

[0029] A first thickened layer 8 is fixedly installed on the outer end of the second stabilizing block 7, and a first support block 9 is fixedly installed on the outer side of the first thickened layer 8. A first fixing ring 10 is fixedly installed on the outer end of the first support block 9. A second thickened layer 11 is fixedly connected to the right side of the first fixing ring 10, and a second support block 12 is fixedly installed on the outer side of the second thickened layer 11. A second fixing ring 13 is fixedly installed on the outer side of the second support block 12. A third thickened layer 14 is fixedly connected to the right side of the second fixing ring 13, and a third support block 15 is fixedly installed on the outer side of the third thickened layer 14. A third fixing ring 16 is fixedly installed on the outer side of the third support block 15.

[0030] For example, such as Figure 2 As shown, an outer rigid tube 1 is fixedly installed at the outer end of the reinforcing layer 5, an inner rigid tube 2 is fixedly installed inside the outer rigid tube 1, an installation interlayer 3 is fixedly opened on the outer side of the inner rigid tube 2, and a transport space 4 is fixedly opened inside the inner rigid tube 2.

[0031] For example, such as Figure 3 As shown, the reinforcing layer 5 and the mounting interlayer 3 form a fixed installation. The first stabilizing block 6 and the second stabilizing block 7 have the same structure, and the interior of the first stabilizing block 6 is a hollow structure.

[0032] For example, such as Figure 3 As shown, the first stabilizing block 6 has six sets of structures, and each set has three blocks. The inner wall of the first thickened layer 8 and the reinforcing layer 5 are fixedly connected. The first support block 9, the second support block 12 and the third support block 15 have the same structure. The first support block 9 is triangular in shape. The first fixing ring 10, the second fixing ring 13 and the third fixing ring 16 have the same structure.

[0033] For example, such as Figure 3As shown, the first fixing ring 10 and the second fixing ring 13 are symmetrically installed on the left and right sides of the first stabilizing block 6 with the first stabilizing block 6 as the central reference, and the second fixing ring 13 and the third fixing ring 16 are symmetrically installed on the left and right sides of the second stabilizing block 7 with the second stabilizing block 7 as the central reference.

[0034] For example, such as Figure 2 As shown, the outer rigid tube 1 and the inner rigid tube 2 have the same structure, and the inner wall of the outer rigid tube 1 and the upper surface of the first fixing ring 10 are connected in a close fit.

[0035] In some examples, an installation interlayer 3 is created inside the original vinyl chloride polymer rigid pipe, thus dividing the vinyl chloride polymer rigid pipe into an outer rigid pipe 1 and an inner rigid pipe 2. A pressure-resistant structure is installed in the installation interlayer 3. This structure mainly consists of a reinforcing layer 5 connecting and fixing a first stabilizing block 6 and a second stabilizing block 7. The upper layer of the reinforcing layer 5 is carbon fiber. The first stabilizing block 6 and the second stabilizing block 7 are designed as hexagonal hollow structures. This design effectively supports the reinforcing layer 5 while significantly reducing the overall weight of the rigid pipe. A first thickened layer 8 and a second thickened layer are respectively set on the left and right sides of the first stabilizing block 6. 11. A second thickened layer 11 and a third thickened layer 14 are respectively set on both sides of the second stabilizing block 7. Multiple support blocks are installed between these thickened layers and the fixing ring. The cross-section of the first support block 9 is designed as a triangular structure. The mechanical stability of the triangle is used to stabilize and support the upper end of the thickened layer, effectively resisting pressure. The support blocks and stabilizing blocks are installed in an alternating manner in the internode, mimicking the structural characteristics of bamboo internodes. By locally strengthening the wall thickness at key positions inside the tube (stabilizing block, thickened layer, support block area), the goal of significantly improving its compressive strength while reducing the overall weight of the rigid tube is achieved.

[0036] For example, such as Figure 4 As shown, this invention illustrates a high-pressure resistant polyvinyl chloride polymer rigid pipe in another embodiment of the present invention, comprising a corrosion-resistant layer 17 fixedly installed inside the transport space 4, an anti-aging layer 18 fixedly installed on the outside of the outer rigid pipe 1, a substrate layer 19 fixedly installed at the outer end of the anti-aging layer 18, a wear-resistant layer 20 fixedly installed at the outer end of the substrate layer 19, a protective sleeve 21 fixedly connected to the outer end of the wear-resistant layer 20, and a reinforcing rib 22 fixedly installed at the outer end of the protective sleeve 21.

[0037] For example, such as Figure 4 As shown, the protective sleeve 21 is a detachable structure, and the protective sleeve 21 is connected to the outer hard tube 1 through the wear-resistant layer 20. The number of reinforcing ribs 22 is five.

[0038] In some examples, the rigid tube adopts a material gradient from the inside to the outside. The inner layer uses a corrosion-resistant layer 17, the middle reinforcing layer 5, and the outer anti-aging layer 18. The corrosion-resistant layer 17 has an epoxy powder coating on its surface, the reinforcing layer 5 has carbon fiber on its surface, and the anti-aging layer 18 has carbon black added to its surface. The combination of the above-mentioned different functional materials significantly improves the corrosion resistance, mechanical strength, and anti-aging ability of the rigid tube, thereby extending its overall service life. A substrate layer 19 is added to the outside of the anti-aging layer 18. The substrate layer 19 fixes the wear-resistant layer 20. The surface of the wear-resistant layer 20 is made of silicon nitride. The addition of silicon nitride to the substrate layer 19 and the wear-resistant layer 20 greatly enhances the wear resistance of the outer surface of the outer rigid tube 1. A protective sleeve 21 is installed at the outermost end of the outer rigid tube 1. The protective sleeve 21 protects the rigid tube body during transportation. Reinforcing ribs 22 are added to the outer surface of the protective sleeve 21 to significantly enhance its impact and compression resistance. The protective sleeve 21 is designed as a recyclable structure, which improves the transportation protection effect and effectively reduces the transportation cost of the rigid tube.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
