Description

Technical Field

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

[0002] Pipelines are devices made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. However, during the use of pipelines, especially in automobiles, excessive internal pressure often leads to cracks or damage, causing fluid substances inside the pipeline to leak out from the damaged area, resulting in waste of resources and making maintenance very inconvenient. Utility Model Content

[0003] To overcome the shortcomings of excessive internal pressure often leading to pipe cracking or damage, resulting in the leakage of fluid substances from the pipe, wasting resources, and causing great inconvenience in maintenance, this utility model provides a composite pressure-resistant pipe.

[0004] The technical implementation scheme of this utility model is as follows: a composite pressure-resistant pipe includes an inner pipe; it also includes an outer pipe, connecting blocks, limiting rings, exhaust pipes, connecting rods, sealing blocks, and sponge blocks; several connecting blocks are connected to the inner pipe; all connecting blocks are fixedly connected to the outer pipe, and each outer pipe has several through holes; several limiting rings are connected to the inner pipe; the other end of each limiting ring is fixedly connected to the outer pipe; several exhaust pipes are connected to the outer pipe, each exhaust pipe has an exhaust port, and the exhaust port communicates with the through holes; several connecting rods are fixedly connected to the inner pipe; a sealing block is fixedly connected to each connecting rod, and the sealing block is slidably connected to the exhaust pipe; a sponge block is fixedly connected to each connecting rod, and the sponge block is located between the outer pipe and the connecting blocks.

[0005] More preferably, the outer tube is a composite tube with aramid fiber as the main material.

[0006] More preferably, the inner tube is a composite tube with polyethylene fiber as the main material.

[0007] More preferably, a pressure sensor is installed inside the exhaust pipe.

[0008] Compared with the prior art, the present invention has the following advantages: The present invention expands the inner tube and squeezes the limiting ring and the sponge block, that is, it relieves the pressure generated by the expansion. At the same time, the inner tube drives the connecting rod to move downward, and the connecting rod drives the sealing block to slide downward in the exhaust pipe, so that the through hole is connected to the exhaust port. The negative pressure generated after the inner tube expands is relieved through the through hole and the exhaust port. In addition, during the expansion process, the inner tube is protected by the outer tube, which prevents the inner tube from contacting other parts in the car after expansion, and prevents the inner tube from being blocked by other parts in the car, which would prevent the inner tube from expanding.

[0015] Example 1

[0016] A composite pressure-resistant pipe, such as Figures 1-4 As shown, it includes an inner tube 3;

[0017] It also includes an outer pipe 1, connecting blocks 2, limiting rings 4, exhaust pipes 5, connecting rods 6, sealing blocks 7, and sponge blocks 8; several connecting blocks 2 are connected to the inner pipe 3 in groups of three; all connecting blocks 2 are fixedly connected to the outer pipe 1, and each outer pipe 1 has several through holes 1001 with eight equidistant distributions; several limiting rings 4 are connected to the inner pipe 3; the other end of all limiting rings 4 is fixedly connected to the outer pipe 1; several exhaust pipes 5 with eight equidistant distributions are connected to the outer pipe 1, and each exhaust pipe 5 has an exhaust port 5001, which communicates with the through holes 1001; several connecting rods 6 with eight equidistant distributions are fixedly connected to the inner pipe 3; each connecting rod 6 is fixedly connected to a sealing block 7, which is slidably connected to the exhaust pipe 5; each connecting rod 6 is fixedly connected to a sponge block 8, which is located between the outer pipe 1 and the connecting blocks 2.

[0018] The outer tube 1 is a composite tube made primarily of aramid fiber, mainly used to improve strength and heat resistance, suitable for high temperature and high pressure environments, and also to protect the inner tube 3 after expansion.

[0019] Inner tube 3 is a composite pipe with polyethylene fiber as the main material. It is mainly used to improve the expansion performance of the pipeline when the temperature changes, relieve pressure through expansion, and improve the heat resistance.

[0020] A pressure sensor is installed inside the exhaust pipe 5 to detect the pressure on the inner pipe 3 and take corresponding measures based on the value, such as unblocking, closing, and reducing the pressure on the inner pipe 3.

[0021] First, the staff installs the composite pressure-resistant pipe. During the use of this pipe, specifically when transporting liquids or gases, it's important to understand that existing automotive piping primarily functions to transport liquids and gases. Protecting the pipes from external exposure, the pressure they experience mainly comes from the liquids and gases being transported within. The main causes include: thermal expansion and contraction (the fluid's volume expands as its temperature rises, increasing pressure within the pipe); and pipe blockage (blockage prevents fluid flow, further increasing pressure). Excessive pressure often leads to pipe rupture. To address issues such as damage, during the operation of this equipment, liquids or gases are transported through the inner tube 3. When the fluid temperature rises, causing volume expansion and blockage within the pipe, excessive pressure can occur in the inner tube 3. The transported liquid and gas will then compress the inner tube 3, causing it to expand and compress the limiting ring 4 and the sponge block 8. This expansion releases the pressure. Simultaneously, the inner tube 3 moves the connecting rod 6 downwards, which in turn moves the sealing block 7 downwards within the exhaust pipe 5, connecting the through hole 1001 to the exhaust port 5001. The expansion of the inner tube 3 through the through hole 1001 and the exhaust port 5001 further facilitates the expansion of the inner tube 3. The resulting negative pressure is released, and the through hole 1001 and vent 5001 are sealed by the sponge block 8 to prevent a large amount of moisture from entering the gap between the outer tube 1 and the inner tube 3 through the through hole 1001 and vent 5001, thus improving the waterproof effect. The sponge block 8 can also absorb residual moisture in the outer tube 1 and inner tube 3, and during the compression process, the water is squeezed out and discharged through the through hole 1001 and vent 5001. Furthermore, during the expansion of the inner tube 3, the outer tube 1 protects the expanding inner tube 3, preventing it from contacting other components inside the car and protecting it from damage caused by the vapor. The obstruction caused by other components inside the vehicle prevents the inner pipe 3 from expanding. If the inner pipe 3 expands, it will freeze and reduce the space between the outer pipe 1 and the inner pipe 3, thereby compressing the air and affecting the expansion size of the inner pipe 3. Therefore, the air needs to be discharged. The double-layer setting of the outer pipe 1 and the inner pipe 3 is used to relieve the pressure generated in the inner pipe 3. In addition, some exhaust pipes 5 of this equipment are equipped with pressure sensors. One pressure sensor is set every 20 centimeters in the exhaust pipe 5 and is triggered by the sealing block 7. That is, the sensor alerts the staff so that the staff can take emergency measures to solve the problem of excessive pipeline pressure.

[0022] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
