Description

Technical Field

[0001] The present invention belongs to the technical field of straight pipe joints, and more specifically, particularly relates to a ferrule type butt straight pipe joint. Background Art

[0002] The ferrule type pipe joint is a sealed pipe joint applicable to non-corrosive or corrosive media such as oil, water, gas, etc. The specification requirements for matching with aluminum-plastic pipes are relatively flexible. After being connected to the pipeline, it has the characteristics of reliable connection and good sealing performance. Therefore, it is widely used in systems such as oil refining, chemical industry, light industry, textile, national defense, metallurgy, aviation, and shipbuilding; it is also applicable to hydraulic transmission pipelines of various mechanical engineering and machine tool equipment.

[0003] Although the existing ferrule type butt straight pipe joints can meet the hydraulic transmission of equipment, they are only single-connected. If greater hydraulic pressure and transmission power need to be borne, it is necessary to replace the aluminum-plastic pipe with a larger inner diameter or use a multi-pipe transmission method. At the same time, the overall joint will be replaced for aluminum-plastic pipes with different inner diameters, which not only wastes materials, has low disassembly and assembly convenience, but also easily leads to problems such as poor sealing and leakage, cannot meet the different adjustment requirements of equipment, and cannot install and connect aluminum-plastic pipes of multiple specifications, with a small scope of use and lack of flexibility.
