Problems solved by technology

[0003] Although the existing PE water supply pipes have good performance due to the characteristics of PE materials, they are prone to freezing and cracking when the temperature is low in winter, causing the water pipes to be unable to use normally, and the pressure in the existing PE water pipes is relatively high When the connection between the pipes is not firm enough, it will cause water leakage between the pipes and the joints. In winter, the water pipes are easy to freeze, and the volume becomes larger after freezing, which is easy to break the water pipes.

Embodiment 1

[0028] Embodiment one, as Figure 1-Figure 6 As shown, a PE water supply pipe according to the present invention includes a PE water supply pipe main body 1 and a water pipe connector 2, a corrugated pipe 1a is installed on the water pipe main body 1, and the water pipe connector 2 is arranged on the PE water supply pipe main body 1, the main body 1 of the PE water supply pipe is composed of a PE pipe inner layer 11, a nano-antibacterial layer 12, a filter layer 13, a PE pipe outer layer 14 and a thermal insulation layer 15, and the PE pipe inner layer 11, the nano-antibacterial layer 12, The filter layer 13, the PE pipe outer layer 14 and the insulation layer 15 are arranged sequentially from the inside to the outside, the outer wall of the PE pipe inner layer 11 is provided with a nano-antibacterial layer 12, and the outer wall of the nano-antibacterial layer 12 is provided with a filter layer 13 , the outer wall of the filter layer 13 is provided with a PE pipe outer layer ...

specific Embodiment 2

[0036] Specific embodiment two, such as Figure 7 As shown, on the basis of Embodiment 1, the two-way connection sleeve 21 is replaced by a right-angle connection sleeve 26. When the water pipes are connected, the ends of the pipes are cut flat with an electric rotary knife to ensure that the contact surfaces of the two pipes can be fully connected. The two PE pipes that need to be installed and connected are placed on the fixture of the fuser at the same time (the fixture can be replaced according to the diameter of the pipe to be installed), and the other end of each pipe is held up to the same level by the pipe bracket. After the connection end of the main body 1 of the water supply pipe is melted, it is quickly inserted into the insertion groove 22 at one end of the right-angle connection sleeve 26. The diameter of the outer wall of the main body 1 of the PE water supply pipe is slightly larger than the inner diameter of the insertion groove 22, so that the melted PE water ...

specific Embodiment 3

[0037] Specific embodiment three, such as Figure 8 As shown, on the basis of Embodiment 1, the right-angled connecting sleeve 26 is replaced with a three-way connecting sleeve 27. When connecting the water pipes, the ends of the pipes are cut flat with an electric rotary knife to ensure that the contact surfaces of the two pipes can be fully connected. The two PE pipes that need to be installed and connected are placed on the fixture of the fuser at the same time (the fixture can be replaced according to the diameter of the pipe to be installed), and the other end of each pipe is held up to the same level by the pipe bracket. After the connection end of the main body 1 of the water supply pipe is melted, it is quickly inserted into the inside of the insertion groove 22 at one end of the tee connection sleeve 27. The diameter of the outer wall of the main body 1 of the PE water supply pipe is slightly larger than the inner diameter of the insertion groove 22, so that the melted...

Abstract

The invention relates to the field of PE water pipes, and discloses a PE feed water. The PE feed pipe comprises a PE feed pipe body and water pipe connecting pieces, wherein the water pipe connectingpieces are arranged at the two ends of the PE feed pipe body. An arranged nano antibacterial layer can effectively prevent external bacteria from intruding into the inside of the pipeline, an arrangedfilter layer can effectively filter a liquid in the pipeline, and an arranged thermal insulation layer can insulate the pipeline when the pipeline is at the low temperature, so that the PE feed pipeis better in antimicrobial performance, filtering performance and thermal insulation performance; PE feed pipe reinforcing ribs are arranged, and when the water pipe bears a large internal and external pressure, the reinforcing ribs can enable the pressure resistance effect of the PE feed pipe to be better; when each water pipe is connected, through arranged fusion welding caulking grooves arranged on the inner walls of inserting grooves in the water pipe connecting pieces, when the PE water pipes are in hot melting connection, and the outer walls of the water pipes are extruded into the inside of embedding grooves after hot-melted, so that the pipeline connection is firmer, the sealing performance is better, and the connection effect between the PE feed pipes is better.

Description

technical field [0001] The invention relates to the field of PE water pipes, in particular to a PE water supply pipe. Background technique [0002] my country's plastic pipes are developing rapidly, and the quality is constantly improving. Among them, polyethylene PE pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrical and telecommunications protection casings, industrial pipes, agricultural pipes, etc. due to their unique advantages. It is mainly used in urban water supply, urban gas supply and farmland irrigation and other fields. [0003] Although the existing PE water supply pipes have good performance due to the characteristics of PE materials, they are prone to freezing and cracking when the temperature is low in winter, causing the water pipes to be unable to use normally, and the pressure in the existing PE water pipes is relatively high At the same time, the connection between the pip...
