Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe fittings, in particular to a PE pipe fitting quick connection device. Background Art

[0002] PE resin is made by polymerizing the monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins of different densities can be obtained. Therefore, there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. When processing different types of PE pipes, different resin brands are selected according to their application conditions. At the same time, the requirements for extruders and molds are also different. The produced PE pipes are divided into five grades: PE32, PE40, PE63, PE80, and PE100. In China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all have a place, among which the strong development momentum of PE pipes is the most eye-catching.

[0003] PE pipes are also frequently used in daily life. Since PE pipes are widely used in various fields, some PE pipes are damaged or broken in daily use. This requires processing of the damaged parts. Generally, a new pipe is directly connected. In general, a hot melt gun is used to assist in the connection. However, when encountering some pipes with larger diameters, the hot melt gun is not effective. For this reason, this scheme proposes a PE pipe quick connection device. Utility Model Content
