Description

Technical Field

[0001] The utility model relates to the technical field of PE pipes, in particular to a new type of PE pipe that is sun-proof and anti-freezing and cracking. Background Art

[0002] The chemical name of PE in Chinese is polyethylene. PE material is widely used in the field of water supply and drainage manufacturing due to its high strength, high temperature resistance, corrosion resistance, non-toxicity and wear resistance. Because it does not rust, it is an ideal pipe to replace ordinary iron water pipes.

[0003] Existing PE pipes are commonly used in the construction industry, and many of them are exposed to the outside when laying pipes. The external PE pipes are exposed to the air for a long time. In the extremely low temperature in winter, the internal liquid may freeze, thereby increasing the volume of water flow and freezing the PE pipe. In the long-term sunlight exposure in summer, it will also cause damage to the PE pipe, thereby reducing the service life of the PE pipe. For this purpose, a new type of PE pipe with sun protection and anti-freeze cracking is provided (see patent number: 202021856373.6 for details), including a PE pipe body, a reinforcing layer is fixedly installed on the outer end of the PE pipe body, and a sun screen is fixedly installed on the outer end of the reinforcing layer. The cross-sections of the PE pipe body, the reinforcing layer and the sun screen are all annular structures, and the PE pipe body, the reinforcing layer and the sun screen are concentric rings. One end of the inner end of the PE pipe body is fixedly installed with an anti-freeze cracking inner sleeve. This new type of sun-proof and frost-proof PE pipe can create a certain buffer space inside the PE pipe body by installing an anti-freeze cracking inner sleeve, thereby preventing water from freezing and expanding after filling the pipe, causing the PE pipe body to freeze and crack. The closed inner sleeve and the curved inner sleeve are made of elastic material. The curved inner sleeve, the closed inner sleeve and the inner wall of the PE pipe body are tightly fitted to form a closed space, thereby preventing the closed inner sleeve and the curved inner sleeve from failing after the new type of PE pipe is cut.

[0004] However, some PE pipes currently available on the market have poor wear resistance during use and often need to be replaced, which greatly increases the cost of use and maintenance. At the same time, some PE pipes, although they have a sun-proof and anti-freeze cracking outer layer, cannot be replaced at the damaged part and the entire pipe can only be replaced, which greatly increases the cost of use and delays use. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that some existing PE pipes on the market have poor wear resistance during use and often need to be replaced, which greatly increases the cost of use and maintenance. At the same time, some PE pipes have a sun-proof and anti-freeze cracking outer layer, but the damaged parts cannot be replaced and the entire pipe can only be replaced, which greatly increases the cost of use and delays the use. The utility model provides a new PE pipe that is sun-proof and anti-freeze cracking.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new type of PE tube for sun protection and frost crack prevention, comprising a PE tube, a protective net provided on the outside of the PE tube, a protective member provided on the outside of the protective net, the protective member comprising a protective layer, a card block provided on the top of the protective layer, a card slot provided on the outside of the card block, protrusions provided on both ends of the card block away from the card slot, multiple groups of magnets provided on the inside of the protective layer, and limit grooves provided on the outside of the multiple groups of magnets.

[0007] As a further solution of the present invention: a filler is provided on the outside of the protective net, and the PE pipe is adhesively connected to the protective layer through the filler.

[0008] As a further solution of the present invention: the protective layer is made of polyvinyl chloride.

[0009] As a further solution of the present invention: the protective layer is detachably connected to the filler through a card slot, a card block, a protrusion and a Velcro.

[0010] As a further solution of the present invention: multiple groups of protective layers are magnetically connected to each other through magnets and limiting grooves.

[0011] As a further solution of the present invention: the inner wall of the PE pipe is coated with a layer of high chromium alloy material.

[0012] Compared with the prior art, the beneficial effects of the present invention are: when in use, materials are transported in the PE pipe, and the wear-resistant coating provided can effectively prevent the wear and damage to the inner wall during material transportation, and the protective net can ensure the service life of the pipe. The external protective layer provides sun protection and heat preservation effects. After long-term use, the protective layer needs to be replaced. Pull the connection point of the protective layer to open the Velcro, and the card block is separated from the slot. Then, the magnet of the damaged protective layer is removed from the limit slot, and the new protective layer is placed. First, the magnets on both sides are aligned with the corresponding limit slots for adsorption, and then the protective layer is fitted with the filler, and the card block is stuck in the slot. The Velcro is adhered to complete the replacement of the new protective layer. This device is easy to use and has a simple structure. The wear-resistant coating and protective net provided can effectively reduce the wear of the inner wall of the pipe during material transportation, while increasing the toughness and service life of the pipe. The protective parts provided can provide sun protection and heat preservation effects, and at the same time, it is convenient to replace and install the damaged parts separately, which is more convenient to use.
