Description

Technical Field

[0001] The present invention relates to the technical field of pipes, and in particular to a highly impact-resistant modified PPR pipe. Background Art

[0002] PPR is the abbreviation of type III polypropylene, also known as random copolymer polypropylene pipe. It adopts the method of heat fusion welding and has special welding and cutting tools. It has high plasticity and is very economical. It has an additional insulation layer for better thermal insulation performance. The pipe wall is also very smooth, excluding the joints of internal and external threads. It is generally used for embedded walls or deep well pre-buried pipes. PPR pipes are moderately priced, stable in performance, heat-resistant and heat-insulating, corrosion-resistant, with a smooth inner wall that does not scale, making the pipeline system safe and reliable and impermeable.

[0003] Traditional PPR pipes have poor impact resistance and are easily damaged when used in environments with strong water pressure, which reduces the service life of PPR pipes. In addition, PPR pipes are generally installed underground, which makes the installation and replacement of PPR pipes more troublesome, thus affecting the use of pipeline transportation. Therefore, we need to design a modified PPR pipe with stronger impact resistance. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that the impact resistance is poor and the PPR pipe is easily damaged after long-term use, and to propose a highly impact-resistant modified PPR pipe.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A highly impact-resistant modified PPR pipe comprises a pipe body, the inner wall of the pipe body being sealed against an inner tube, two symmetrically arranged storage cavities being provided inside the inner tube, a plurality of partitions being fixed to the inner wall of each storage cavity, the plurality of partitions dividing the storage cavity into a plurality of storage spaces, each of the storage spaces being filled with a buffer, a plurality of fixing rings being fixed to the outer wall of the pipe body, the inner wall of the pipe body being connected to the outer wall of the inner tube by a plurality of limiting devices, and a plurality of reset devices being provided at the upper end of one of the fixing rings.

[0007] Preferably, the limiting device comprises a horizontal groove formed on the inner wall of the pipe body, the inner wall of the horizontal groove is sealingly and slidingly connected to a limiting block, and the side wall of the limiting block is connected to the inner wall of the horizontal groove via a connecting spring.

[0008] Preferably, a slot is provided on the outer wall of the inner tube, and the limiting block corresponds to the slot.

[0009] Preferably, the reset device includes a vertical groove opened at the upper end of the fixing ring, the inner wall of the vertical groove is slidably connected with a suction block, and the bottom of the suction block is connected to the bottom of the vertical groove through a support spring.

[0010] Preferably, the plurality of reset devices correspond one-to-one to the plurality of limit devices, and the limit blocks correspond to the suction blocks.

[0011] Preferably, the limiting block is made of ferrous metal material, the suction block is a permanent magnet, and the connecting spring and the supporting spring are both made of rubber material.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] 1. In this device, by arranging multiple fixing rings on the outside of the pipe body, the strength of the pipe body can be effectively increased, so that the impact resistance of the modified PPR pipe is better. Combined with the inner tube located inside the pipe body and the flexible buffer inside the inner tube, the overall impact resistance of the modified PPR pipe can be made stronger, thereby facilitating the use of the modified PPR pipe in high-pressure environments and making the use of the modified PPR pipe more extensive.

[0014] 2. In this device, multiple corresponding limit devices and reset devices are set at the same time. When the suction block, which is a permanent magnet, is pressed downward, the limit block made of ferrous metal material can be moved, thereby facilitating the stable sealing installation of the pipe body and the inner tube, and making the disassembly of the inner tube more convenient.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 , a highly impact-resistant modified PPR pipe, comprising a pipe body 1, the inner wall of the pipe body 1 is sealed against an inner tube 2, and the interior of the inner tube 2 is provided with two symmetrically arranged storage cavities 3, the inner wall of each storage cavity 3 is fixed with multiple partitions 4, and multiple partitions 4 divide the storage cavity 3 into multiple storage spaces 5, and each storage space 5 is filled with a buffer 6, which is made of flexible material. The flexible material can be used to buffer the impact of high-pressure liquid, thereby making the impact on the pipe body 1 smaller, which can make the use of the pipe body 1 safer. The outer wall of the pipe body 1 is fixed with multiple fixing rings 7. The use of multiple fixing rings 7 can effectively increase the strength of the pipe body 1, and combined with the buffering protection of the pipe body 1 by the inner tube 2, the modified PPR pipe can have stronger impact resistance and a wider range of use. The inner wall of the pipe body 1 and the outer wall of the inner tube 2 are connected by multiple limit devices, and the upper end of one of the fixing rings 7 is provided with multiple reset devices.

[0021] The limiting device includes a horizontal groove 8 opened on the inner wall of the pipe body 1, and the inner wall of the horizontal groove 8 is sealed and slidably connected to the limiting block 9, and the side wall of the limiting block 9 is connected to the inner wall of the horizontal groove 8 by a connecting spring 10; the outer wall of the inner tube 2 is provided with a card groove 11, and the limiting block 9 corresponds to the card groove 11; the reset device includes a vertical groove 12 opened at the upper end of the fixing ring 7, and the inner wall of the vertical groove 12 is slidably connected to the suction block 13, and the bottom of the suction block 13 is connected to the bottom of the vertical groove 12 by a supporting spring 14; multiple reset devices correspond one-to-one to multiple limiting devices, and the limiting block 9 corresponds to the suction block 13; the limiting block 9 is made of iron metal material, the suction block 13 is a permanent magnet, and the connecting spring 10 and the support spring 14 are both made of rubber material. By using multiple corresponding limiting devices and reset devices, the stable sealing installation of the pipe body 1 and the inner tube 2 can be facilitated, and the disassembly of the inner tube 2 can be more convenient.

[0022] In the present invention, during the use of the modified PPR pipe, the inner tube 2 is sealed and inserted into the interior of the pipe body 1 by aligning the outer wall of the inner tube 2 and the inner wall of the pipe body 1, so that the inner tube 2 is sealed against the inner wall of the pipe body 1, and the inner tube 2 is pushed along the inner wall of the pipe body 1. When the bottom of the inner tube 2 is against the limit block 9, the suction block 13 inside the vertical groove 12 is pressed to make the suction block 13 slide downward along the inner wall of the vertical groove 12. During the movement of the suction block 13, the compression of the support spring 14 can be achieved. When the suction block 13 is at the same height as the horizontal groove 8, the suction block 13, which is a permanent magnet, has an adsorption effect on the limit block 9 made of ferrous metal material, so that the limit block 9 can slide toward the inside of the horizontal groove 8. At the same time, during the movement of the limit block 9, Now compress the connecting spring 10. After the limit block 9 completely enters the horizontal groove 8, continue to press the inner tube 2 so that the inner tube 2 passes the position of the horizontal groove 8. At this time, release the suction block 13. Under the action of the support spring 14 in the compressed state, the suction block 13 can be quickly reset, thereby realizing the separation of the suction block 13 from the limit block 9, so that the magnetism of the suction block 13 and the limit block 9 is weakened, so that under the action of the connecting spring 10 in the compressed state, the limit block 9 is abutted against the outer wall of the inner tube 2. When the groove 11 on the outer wall of the inner tube 2 corresponds to the horizontal groove 8, the limit block 9 can quickly enter the inside of the groove 11 under the action of the connecting spring 10 in the compressed state, thereby realizing the quick connection between the pipe body 1 and the inner tube 2, and making the disassembly of the inner tube 2 more convenient.

[0023] During the use of the modified PPR pipe, the multiple fixing rings 7 fixed on the outer wall of the pipe body 1 can enhance the strength of the pipe body 1, thereby making the modified PPR pipe more resistant to impact. The inner tube 2 and the internal flexible buffer 6 can be used to cushion the impact of the inner tube 2, thereby reducing the impact of the pipe body 1 when the high-pressure liquid flows, thereby making the modified PPR pipe more resistant to impact, avoiding impact damage to the modified PPR pipe, and extending the service life of the modified PPR pipe.

[0024] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
