Description

Technical Field

[0001] The invention relates to the technical field of PPR water supply pipes, in particular to a self-cleaning flow-increasing PPR water supply pipe. Background Art

[0002] PPR is a random copolymer polypropylene synthesized by the gas phase method. Its structural feature is that PE molecules are randomly linked in PP molecules. The water pipes produced using PPR raw materials are also called random copolymer polypropylene pipes. With their excellent performance and a wide range of applications, they have occupied a place in the plastic pipe market and are recognized as green and environmentally friendly products.

[0003] After checking the public (announcement) number: CN114458841A, a reinforced PPR water supply pipe is disclosed, including a central pipe, a threaded groove, a coiled pipe, a fixed pipe, a protective sleeve, a first closed pipe, a connecting pipe, a rotating connecting block, a guide connecting block and a second closed pipe. A threaded groove is provided on the inner wall of the central pipe. The present invention improves the pipe body strength of the water supply pipe by winding a coiled pipe around the outside of the central pipe and connecting a fixed pipe outside the coiled pipe, thereby avoiding the breakage of the pipe material and ensuring the water supply reliability of the water pipe. The threaded groove provided on the inner wall of the central pipe cooperates with the first threaded sleeve to complete the installation and fixation of the first closed pipe. There is no need to use a thermoplastic method to install the bent pipe, which reduces the labor intensity of installation at corners. The water supply direction of the water pipe is changed by rotating the connecting pipe, and the water supply angle of the water pipe is changed by rotating the rotating connecting block, which is convenient for adjusting the bending direction of the pipeline, thereby improving the practicability of the water pipe.

[0004] Based on the above-mentioned prior art, the existing PPR water supply pipes still have the following problems: traditional PPR pipes have the problem of easy deposition of dirt on the inner wall, which will affect the service life of the pipes. At the same time, the connection between pipes is too cumbersome, and when replacing the pipes, the water valve needs to be closed to drain the water inside the pipes, resulting in a waste of water resources. For this reason, the present invention provides a self-cleaning and flow-increasing PPR water supply pipe. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 , the present invention provides a technical solution:

[0028] A self-cleaning flow-increasing PPR water supply pipe, comprising a self-cleaning flow-increasing PPR water supply pipe 1, which is used for water pipes to achieve self-cleaning flow-increasing and to achieve quick connection between water pipes. The self-cleaning flow-increasing PPR water supply pipe 1 comprises:

[0029] The PPR water supply pipe unit 11 includes an inner wall 111, and a polypropylene hydrophobic masterbatch coating 112 is fixedly installed inside the inner wall 111;

[0030] The connecting unit 12 is arranged at the end of the PPR water supply pipe unit 11, and includes a left connecting head 121 and a right connecting head 129. A connecting pipe 122 is fixedly installed on one end of the left connecting head 121, and a threaded sleeve 1213 is rotatably installed on the surface of the right connecting head 129, and the threaded sleeve 1213 is threadedly rotatably installed on the surface of the connecting pipe 122.

[0031] A polypropylene hydrophobic masterbatch coating 112 is installed inside the inner wall 111, which has the characteristics of high hydrophobicity (the hydrophobic effect can be adjusted according to product requirements) and low adhesion, and can achieve low or no residue on the surface of the material, without the need for secondary coating, a fluorine-free formula, safety and environmental protection, thereby achieving self-cleaning and flow increase of the PPR water supply pipe.

[0032] Polypropylene hydrophobic masterbatch MGP002 is also called hydrophobic agent or water repellent. It is a compound that can aggregate on the surface of materials to reduce surface tension and hydrophilicity. It is widely used in many fields because of its extreme repellency to water. Mechanism of action The hydrophobic effect is a relatively complex mechanism, and its origin is not yet fully understood. Nevertheless, there are still some viewpoints that have certain reference value. It can be agreed that the source of the hydrophobic effect is the important property that water can form strong hydrogen bonds.

[0033] Hydrophobic groups and hydrophilic groups are mainly divided according to the form of their interaction with water - hydroxyl groups that can form hydrogen bonds are obviously hydrophilic groups, and groups with strong polarity are generally hydrophilic groups. Hydrocarbon groups that do not interact strongly with water (mainly dispersion forces) are generally hydrophobic groups. Theory and experiments have shown that the macroscopic effect that has been fully studied - surface tension can fully explain the performance of hydrophobic interactions on a large scale. (Extended reading: The research team of Professor Wang Wei and Professor Cao Yi of Nanjing University has made new progress in the study of hydrophobic interactions)

[0034] In this embodiment, the outer circle of the inner wall 111 is fixedly mounted with reinforcing ribs 113 , and the reinforcing ribs 113 are arranged in a folded shape on the circumference of the outer circle of the inner wall 111 .

[0035] The outer ring of the inner wall 111 is fixedly mounted with reinforcing ribs 113 , and the reinforcing ribs 113 are arranged in a folded shape on the circumference of the outer ring of the inner wall 111 , thereby improving the structural strength and pressure resistance of the pipe.

[0036] In this embodiment, a sound insulation layer 114 is fixedly installed on the outer circle of the reinforcing rib 113 , and an outer wall 115 is fixedly installed on the outer circle of the sound insulation layer 114 .

[0037] The material of the outer wall 115 is a rubber sound insulation pad, which is used to reduce noise transmission.

[0038] In this embodiment, a flame retardant coating 116 is fixedly installed on the outer ring of the outer wall 115 , and a UV stabilizing coating 117 is fixedly installed on the outer ring of the flame retardant coating 116 .

[0039] The material used in the flame retardant coating 116 is a flame retardant, which improves the flame retardant properties of the PPR pipe and makes it safer in the event of a fire. The material used in the ultraviolet stabilizing coating 117 is an ultraviolet stabilizer, which prevents the pipe from aging, fading or performance degradation due to long-term exposure to sunlight.

[0040] In this embodiment, a water-passing plate 123 is fixedly installed inside the connecting pipe 122, a fixing plate 124 is fixedly installed inside the connecting pipe 122, a sliding column 125 is installed inside the fixing plate 124, and a baffle 126 is fixedly installed at one end of the sliding column 125. A spring 127 is sleeved on the surface of the sliding column 125. A rectangular groove 128 is opened at the top and bottom of the inner cavity of the connecting pipe 122, and a sealing plate 1214 is fixedly installed at one end of the sliding column 125 away from the baffle 126, and the sealing plate 1214 is sealed. A rubber pad 1215 is installed on one side of the plate 1214 close to the sliding column 125, a plug 1211 is fixedly installed on one end of the right connecting head 129, a pressure plate 1212 is fixedly installed inside the plug 1211, and one side of the pressure plate 1212 is in contact with the baffle 126, a rectangular slider 1210 is fixedly installed on the top and bottom of the surface of the plug 1211, and the specification size of the rectangular slider 1210 is adapted to the rectangular groove 128, and the rectangular slider 1210 is slidably inserted into the interior of the rectangular groove 128.

[0041] The insert pipe 1211 is inserted into the interior of the connecting pipe 122, and the rectangular slider 1210 is inserted into the interior of the rectangular groove 128. At this time, the user rotates the threaded sleeve 1213 to lock the right connector 129 and the connecting pipe 122, thereby realizing a quick connection between the PPR water supply pipes.

[0042] When the insert tube 1211 is pulled out of the connecting tube 122, the pressure plate 1212 gradually releases the pressure on the baffle plate 126. At the same time, the spring 127 pushes the baffle plate 126 by its own elastic force. The baffle plate 126 drives the sealing plate 1214 and the rubber pad 1215 to move synchronously through the sliding column 125, so that the rubber pad 1215 and the sealing plate 1214 block the water hole of the water plate 123, so that when the connecting unit 12 releases the connection to the pipeline, the water in the water pipe will not flow out and cause waste of water resources.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] During operation, first, the insert pipe 1211 is inserted into the interior of the connecting pipe 122, and the rectangular slider 1210 is inserted into the interior of the rectangular groove 128, the pressure plate 1212 squeezes the baffle 126, and the rubber pad 1215 is no longer sealed with the water passing plate 123. At this time, the user rotates the threaded sleeve 1213 to lock the right connecting head 129 and the connecting pipe 122. When the pipeline is disassembled, the threaded sleeve 1213 is rotated in the opposite direction, the insert pipe 1211 is pulled out of the connecting pipe 122, and the pressure plate 1212 gradually releases the squeezing of the baffle 126. At the same time, the spring 127 pushes the baffle 126 through its own elastic force, and the baffle 126 drives the sealing plate 1214 and the rubber pad 1215 to move synchronously through the sliding column 125, so that the rubber pad 1215 and the sealing plate 1214 block the water through hole of the water passing plate 123.
