Description

Technical Field

[0001] This utility model relates to the field of titanium alloy pipe technology, specifically a quick-connect titanium alloy pipe. Background Technology

[0002] Titanium alloy pipes are pipes made from titanium alloys. Titanium alloys can be classified into three categories according to their microstructure: 1. Titanium with the addition of aluminum and tin; 2. Titanium with the addition of alloying elements such as aluminum, chromium, molybdenum, and vanadium; 3. Titanium with the addition of elements such as aluminum and vanadium. These alloys possess high mechanical properties, excellent stamping performance, and can be welded in various forms. The strength of the welded joint can reach 90% of the strength of the base metal, and they have good machinability. Titanium pipes have high corrosion resistance to chlorides, sulfides, and ammonia. Titanium's corrosion resistance in seawater is higher than that of aluminum alloys, stainless steel, and nickel-based alloys. Titanium also has strong resistance to water impact. Traditionally, titanium alloy pipes are connected using flanges.

[0003] The prior art, patent application number 202222003393.4, describes a quick-connect titanium alloy pipe. Its technical solution includes a titanium alloy pipe, circular grooves symmetrically arranged on the top and bottom of one end of the titanium alloy pipe, and two sets of fixing mechanisms and two sets of driving components symmetrically arranged on the top and bottom of the end of the titanium alloy pipe away from the circular grooves. The fixing mechanism includes a limiting component slidably disposed within one end of the titanium alloy pipe and a gear assembly disposed within the titanium alloy pipe. The gear assembly, limiting component, and driving component engage in transmission. The advantages of this invention are: by setting circular grooves, limiting components, gear assemblies, and driving components on the titanium alloy pipe, the operation steps for connecting the titanium alloy pipe are simple, the time required is short, and no external tools are needed, facilitating workers to quickly connect two sets of titanium alloy pipes together, greatly improving work efficiency. However, the stability of the connection between the two alloy pipes is low, and disassembly and assembly are inconvenient. Utility Model Content
