Description

Technical Field

[0001] This utility model relates to the field of high-pressure pipe technology, specifically to a high-temperature resistant and explosion-proof high-pressure pipe. Background Technology

[0002] In industries such as petrochemicals and heat transmission, high-pressure pipes are key components for transporting high-temperature and high-pressure media. With the continuous expansion of industrial production scale and increasingly stringent process requirements, higher demands are placed on the performance of high-pressure pipes, especially in terms of high-temperature resistance and explosion prevention. Most existing high-pressure pipes are made of a single material, which is prone to softening and deformation under high-temperature conditions, leading to a decrease in the structural strength of the high-pressure pipe and posing a risk of explosion.

[0003] Based on the above, this utility model proposes a high-temperature resistant and explosion-proof high-pressure pipe, which can effectively solve the above problems. Utility Model Content

[0006] A high-temperature resistant and explosion-proof high-pressure pipe includes an inner tube body, wherein a first high-temperature resistant layer and a second high-temperature resistant layer are sequentially arranged from the inside to the outside of the inner tube body. The first high-temperature resistant layer is made of polytetrafluoroethylene, and the second high-temperature resistant layer is made of modified polypropylene. An outer tube body is sleeved on the outside of the inner tube body. The outer tube body includes two semi-circular rings, which are detachably connected by a connecting mechanism.

[0007] According to the above technical solution, as a further preferred technical solution, flanges are fixedly connected to both ends of the inner tube.

[0008] According to the above technical solution, as a further preferred technical solution, the connecting mechanism includes a connecting block fixedly connected to one end of the semi-circular ring and a connecting groove opened at the other end of the semi-circular ring; a protrusion is fixedly connected to one side of the connecting block, and a first inclined surface is provided on the outside of the protrusion of the connecting block; a recessed portion that engages with the protrusion is opened on the inner side of the connecting groove, and a second inclined surface that abuts against the first inclined surface.

[0009] According to the above technical solution, as a further preferred technical solution, the semi-circular ring is provided with a plurality of through holes evenly distributed at equal angles along its length.

[0010] According to the above technical solution, as a further preferred technical solution, the outer tube is made of aluminum alloy.

[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0012] This utility model provides a high-temperature resistant and explosion-proof high-pressure pipe. The inner tube body, made of a first high-temperature resistant layer of polytetrafluoroethylene and a second high-temperature resistant layer of modified polypropylene, possesses excellent high-temperature resistance, enabling stable operation in high-temperature environments and preventing deformation or damage due to high temperatures. Simultaneously, an outer tube body is fitted around the inner tube body.

Furthermore, the outer tube body consists of two detachably connected semi-circular rings, facilitating installation and disassembly. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0019] A high-temperature resistant and explosion-proof high-pressure pipe includes an inner tube body 1. The inner tube body 1 has a first high-temperature resistant layer 11 and a second high-temperature resistant layer 12 arranged sequentially from the inside to the outside. The first high-temperature resistant layer 11 is made of polytetrafluoroethylene, and the second high-temperature resistant layer 12 is made of modified polypropylene. An outer tube body 2 is sleeved on the outside of the inner tube body 1. The outer tube body 2 includes two semi-circular rings 21, which are detachably connected by a connecting mechanism.

[0020] The inner tube 1 of this invention is provided with a first high-temperature resistant layer 11 made of polytetrafluoroethylene and a second high-temperature resistant layer 22 made of modified polypropylene, which gives the inner tube 1 good high-temperature resistance and enables it to work stably in high-temperature environments without easily deforming or being damaged by high temperatures. At the same time, an outer tube 2 is sleeved on the outside of the inner tube 1. When the internal pressure of the inner tube 1 increases, the outer tube 2 can limit the radial expansion of the inner tube 1 and prevent it from bursting due to excessive expansion. Furthermore, the outer tube 2 is composed of two detachably connected semi-circular rings 21, which facilitates installation and disassembly.

[0021] Furthermore, in another embodiment, flanges 13 are fixedly connected to both ends of the inner tube 1.

[0022] By fixing flanges 13 to both ends of the inner pipe body 1, the flange connection method is mature and reliable, which can realize the rapid and stable connection of high pressure pipe with other equipment or pipelines, and ensure the sealing and firmness of the connection.

[0023] Furthermore, in another embodiment, the connecting structure includes a connecting block 22 fixedly connected to one end of the semi-circular ring 21, and a connecting groove 23 opened at the other end of the semi-circular ring 21; a protrusion 221 is fixedly connected to one side of the connecting block 22, and a first inclined surface 222 is provided on the outside of the protrusion 221; a recess 231 that engages with the protrusion 221 is opened on the inner side of the connecting groove 23, and a second inclined surface 232 that abuts against the first inclined surface 222.

[0024] By setting up a connection structure, the protrusion 221 and the recess 231 are engaged and snapped together, and the first inclined surface 222 and the second inclined surface 232 abut against each other, so that the two semi-circular rings 21 are tightly connected and not easy to loosen when subjected to high pressure, thus ensuring the structural integrity and sealing of the outer tube 2. This connection method is easy to install; the connection can be completed simply by inserting the connecting block 22 into the connecting groove 23 and adjusting its position appropriately. Disassembly is also relatively convenient and does not require complicated tools.

[0025] Furthermore, in another embodiment, the semi-circular ring 21 is provided with a plurality of through holes 24 evenly distributed at equal angles along its length.

[0026] By setting through holes 24, the flexibility of the outer tube 2 is increased, so that when it is subjected to external impact or deformation due to temperature changes, it can buffer stress through the slight deformation of the through holes, improve the impact resistance and deformation resistance of the outer tube 2, and enhance the overall durability of the high-pressure pipe.

[0027] Furthermore, in another embodiment, the outer tube 2 is made of aluminum alloy.

[0028] By setting an outer tube 2 made of aluminum alloy, which has advantages such as high strength, light weight and corrosion resistance, the inner tube 1 can be provided with good mechanical protection and prevent the inner tube from being damaged by external physical forces.
