Description
Technical Field
[0001] This utility model relates to the field of PVC pipe technology, and in particular to a pressure-resistant PVC pipe. Background Technology
[0002] PVC pipes are synthetic materials made of polyvinyl chloride resin, stabilizers, lubricants, etc., through hot pressing. Due to their corrosion resistance and low price, they are widely used in drainage, water supply, and chemical fluid transportation. However, during use, PVC pipes can be damaged by external forces. For example, exposed PVC drainage pipes may rupture due to sudden impact pressure, thus affecting their normal use. Utility Model Content
[0003] The purpose of this utility model is to provide a pressure-resistant PVC pipe to address the shortcomings of the existing technology.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0005] A pressure-resistant PVC pipe includes an inner tube with a support plate attached thereon. The support plate fits against the inner and outer walls of the inner tube to protect the inner tube. An outer tube is sleeved on the support plate, and a buffer assembly is provided between the outer tube and the support plate.
[0006] Preferably, the support piece has an arc-shaped structure, and multiple support pieces are spliced together to form a circular structure and fitted onto the inner tube.
[0007] Preferably, the outer wall of the inner tube is provided with a plurality of annular reinforcing ribs, the plurality of reinforcing ribs being evenly arranged along the length direction of the inner tube, and the side wall of the support piece that is in contact with the inner tube is provided with an annular groove, the reinforcing ribs being engaged in the annular groove.
[0008] Preferably, the support sheet is provided with a plurality of support steel wires to enhance the structural strength of the support sheet.
[0009] Preferably, the buffer assembly includes support rods evenly arranged along the circumference, one end of the support rods being fixedly connected to the inner wall of the outer tube, and the other end being slidably connected to the support plate.
[0010] Preferably, the outer wall of the support piece is provided with a groove along its length, and the end of the support rod away from the outer tube is provided with a slider, which is slidably disposed in the groove.
[0011] Preferably, the support rod has a polygonal structure.
[0012] Preferably, a buffer rubber block is filled between two adjacent support rods.
[0013] The beneficial effects of adopting the above technical solution are as follows:
[0014] 1. In this utility model, the inner tube is used to transport fluid. In order to avoid damage to the inner tube due to excessive pressure during the transportation process, a support plate is wrapped around the inner tube. The support plate is provided with a support steel wire to enhance the structural strength. Therefore, the support plate can withstand greater pressure, thereby protecting the inner tube and preventing it from breaking due to excessive pressure.
[0015] 2. In this utility model, if the inner tube is suddenly impacted, the support rod breaks under the impact force, thereby playing a buffering role, reducing part of the impact force, and avoiding direct impact on the inner tube. The buffer rubber blocks between the support rods can further play a buffering and shock-absorbing role, thereby protecting the inner tube and preventing it from being suddenly subjected to large pressure and causing it to break and be damaged.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] In the current pipeline construction field, PVC pipes are generally used as drainage pipes, typically buried deep underground or directly exposed to walls. Pipes buried underground are subjected to immense pressure over long periods. When heavy vehicles pass over the road, the pressure on the pipes increases dramatically, easily causing them to rupture and break. Rainwater drainage pipes exposed to walls are susceptible to external impacts; in the event of a sudden impact, the pipes can also rupture and break due to the force of the impact. Therefore, this utility model provides a pressure-resistant PVC pipe, such as... Figure 1 As shown, it includes an inner tube 1, on which a support plate 2 is provided. The support plate 2 has an arc-shaped structure. Multiple support plates 2 are provided on the outer tube 1. The multiple support plates 2 are spliced together to form a cylindrical structure and are sleeved on the outer wall of the inner tube 1. Adjacent support plates 2 can be fixedly connected by adhesive. The inner side wall of the support plate 2 is in contact with the inner and outer walls of the inner tube 1 to protect the inner tube 1. An outer tube 3 is sleeved on the support plate 2. A buffer assembly is provided between the outer tube 3 and the support plate 2. In this invention, the inner tube 1 is used to transport fluid. Multiple support plates 2 are arranged along the circumferential direction on the outer wall of the inner tube 1. The multiple support plates 2 are spliced and attached to each other on the outer wall of the inner tube 1. Therefore, the support plates 2 can provide protection for the inner tube 1 and prevent the inner tube 1 from being broken or damaged due to excessive external pressure. An outer tube 3 is sleeved on the outside of the support plates 2. A buffer assembly is arranged between the outer tube 3 and the support plates 2. When the pipe is suddenly subjected to a violent impact, the buffer assembly can play a role in buffering and shock absorption, thereby providing protection for the inner tube 1 and preventing the inner tube 1 from being broken or damaged due to impact.
[0026] Furthermore, such as Figure 2As shown, the outer wall of the inner tube 1 is provided with multiple annular reinforcing ribs 4, which are evenly arranged along the length of the inner tube 1. An annular groove 5 is formed on the side wall of the support piece 2 that is in contact with the inner tube 1. When the support piece 2 is in contact with the outer wall of the inner tube 1, the reinforcing ribs 4 are engaged within the annular groove 5. In this embodiment, the reinforcing ribs 4 enhance the structural strength of the inner tube 1, enabling it to withstand stronger pressure. Furthermore, the cooperation between the reinforcing ribs 4 and the annular groove 5 also limits the movement of the support piece 2, preventing it from shifting within the inner tube 1.
[0027] Furthermore, such as Figure 3 As shown, the support plate 2 is provided with multiple support wires 6. The support wires 6 are arc-shaped structures adapted to the support plate 2. The support wires 6 can enhance the structural strength of the support plate 2, thereby improving the compressive strength of the support plate 2 and providing better protection for the inner tube 1.
[0028] Furthermore, such as Figure 1 and Figure 4 As shown, the buffer assembly includes support rods 7 evenly arranged along the circumference and radially arranged along the outer tube 3. One end of the support rod 7 is fixedly connected to the inner wall of the outer tube 3, and the other end is slidably connected to the support piece 2. In this embodiment, after the support piece 2 is attached to the inner tube 1, the inner tube 1 with the support piece 2 attached is fitted into the outer tube 3 and slides along the outer tube 3 until it is completely inserted into the outer tube 3. The support rod 7 can provide support, so that the inner tube 1 is located at the center of the outer tube 3. When the pipe is suddenly impacted, the support rod 7 breaks when subjected to a force exceeding the support rod 7's capacity, which can play a role in buffering and shock absorption, preventing all the impact force from acting on the inner tube 1.
[0029] Furthermore, such as Figure 5 As shown, the outer wall of the support plate 2 is provided with a groove 8 along the length direction, and the end of the support rod 7 away from the outer tube 3 is provided with a slider 9, which is slidably disposed in the groove 8.
[0030] Furthermore, the support rod 7 has a broken line structure, which facilitates the breakage of the support rod 7 and thus prevents the support rod 7 from puncturing the inner tube 1.
[0031] Furthermore, a buffer rubber block 10 is filled between two adjacent support rods 7. The buffer rubber block 10 can also play a buffering role when subjected to impact, thus protecting the inner tube.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
