Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pipeline connection, and more specifically to a multi-way pipe sleeve with a variable number of joints. Background Art

[0002] Pipe fitting is a hydraulic term, which is a part that connects pipes in hydraulic systems or installs pipes on hydraulic components. It is a general term for connectors that can be installed and removed in fluid passages. Existing pipe fittings include one-way, two-way and three-way pipe fittings, which are the most common ones. These pipe fittings in the prior art are produced and used separately, and the production cost is relatively high. Moreover, when a four-way pipe fitting or more pipe fittings are needed, they cannot meet the needs. Moreover, when it comes to multi-pipeline liquid transportation, a single one-way, two-way or even three-way pipe fitting cannot meet the requirements, and its scope of use is limited and narrow.

[0003] The prior art discloses a multi-way pipe joint, including a regular polygonal fluid converter, and a pipe joint is integrally connected to the side of each side of the fluid converter, each of the pipe joints is composed of a pipe joint seat, a plurality of threaded pipes with decreasing outer diameters, and a pipe cap, the pipe joint seat is fixed and connected to the fluid converter, and the plurality of threaded pipes are connected to each other in a sleeve-to-sleeve relationship from large to small in outer diameter, and the threaded pipe with the largest outer diameter is sleeve-connected to the pipe joint seat, and the pipe cap sealedly connected to it is provided on the pipe joint seat. This solution can realize one-way, two-way, three-way or even multi-way pipe joints on a fluid converter, and when a one-way pipe joint is needed, the remaining pipe joints can be fixed and sealed by pipe caps so that no liquid flows out of their ports.

[0004] However, in the prior art, the sealing of each threaded pipe is achieved by threading a pipe cap and a pipe joint. Not only is the sealing difficult to ensure, but the threads are easily corroded under long-term contact with liquid, causing the entire converter to be scrapped. There are technical problems such as poor sealing of the pipe joints of the multi-way conversion tube and unstable sealing effect. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of poor sealing performance and unstable sealing effect of pipe joints of multi-way conversion pipes in the prior art, and provide a multi-way pipe sleeve with a variable number of joints.

[0011] Furthermore, an annular groove is provided between the opposite sides of the plug and the outlet connector. The annular groove is provided between the opposite sides of the plug and the outlet connector to guide and mark the position, making it easy to shear the annular groove using a tool.
