Anti-aging plastic pipe or anti-aging plastic pipe connector

Abstract

The invention relates to an anti-aging plastic pipe or an anti-aging plastic pipe connector, comprising an integrated main pipe body molded by plastics. The anti-aging plastic pipe or anti-aging plastic pipe connector is characterized in that the outer side of the main pipe body is composited with an ultraviolet-proof layer which is mixed with glass powder in a certain proportion, and the outer side of the ultraviolet-proof layer is composited with a protection layer. The anti-aging plastic pipe or anti-aging plastic pipe connector has the advantages that the black ultraviolet-proof layer with glass powder can block the incidence of any light ray, especially ultraviolet rays, so that the aging of the main pipe body, caused by the ultraviolet light, is avoided, the aging rate is obviously reduced, and the service life is prolonged; the anti-aging plastic pipe has the anti-flaming function and can resist low flame ignited by hay, and the strength of the pipe body is increased; and the anti-aging plastic pipe is not molded at the temperature of melting glass, and the processing temperature is reduced, therefore, the normal blow molding technology can be adopted to process and form the ultraviolet-proof layer, and the production efficiency is increased.

Description

technical field

[0001] The invention relates to an anti-aging plastic pipe or a plastic pipe joint, which can be used as a water delivery pipeline for irrigation facilities in agriculture, animal husbandry or forestry, especially for water delivery pipelines used in the open air for irrigation (such as drip irrigation and sprinkler irrigation) facilities in mountainous areas and between them. Connection. It can also be used as a pipeline for oil and natural gas used in the open air. Background technique

[0002] At present, water-saving irrigation technology has been gradually popularized and applied in our country. In plains or areas with soft soil, water pipelines are generally buried underground. In the entire irrigation system, many water pipes are required, including main pipes and branch pipes, and pipe joints are required to connect each pipe. Connecting end) or above, for the interconnection of each water pipe end at the connecting node. In the application of wate...

Embodiment Construction

[0020] see figure 1 , an embodiment of an anti-aging plastic pipe joint of the present invention (a three-way structure, but not limited to a three-way structure), which is composed of a main channel part 1 and a branch channel part 2 of an integrated structure. The layer structure of the main channel part 1 and the branch channel part 2 of the plastic pipe joint is the same, and the inner side is the main body 3 of the pipe body, which is made of plastic, preferably black PE. A layer of anti-ultraviolet layer 4 mixed with glass powder is compounded on the outside of the tube body 3 .

[0021] A protective layer 5 can also be compounded on the outside of the ultraviolet protection layer 4 .

[0022] In this embodiment, the outer peripheral surfaces of the pipe joints of the main passage part 1 and the branch passage part 2 are provided with several rings of ribs 6 for firm connection with plastic pipes.
