Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically an integrated valve friction welding device. Background Technology

[0002] The connecting pipes of the integrated valve are inserted into the bamboo joint by cold extrusion. Due to the cold extrusion method, gaps are easily generated between the connecting pipes and the bamboo joint during assembly or after a period of use, which affects the stability of the vehicle control system.

[0003] A search of Chinese patent CN206290772U reveals a one-way valve assembly using rotary friction welding. The top surface of the annular portion is welded to the bottom surface of the annular groove via rotary friction welding. This welding connects the top surface of the annular portion and the bottom surface of the annular groove in a molten state, effectively fusing the upper and lower housings into one unit. This significantly increases the connection strength at the junction of the upper and lower housings, ensuring a secure connection during assembly and use, reducing the risk of fluid leakage and guaranteeing operational stability. The second annular body, inserted into the gap, provides mutual support between the second annular body, the annular portion, and the convex ring, further enhancing structural strength. A receiving groove is formed between the convex block, the bottom surface of the annular groove, and the inner circumference of the annular groove to accommodate the molten material from the rotary friction welding. This allows slag or excess molten material generated during rotary welding to be discharged into the receiving groove, ensuring assembly accuracy and further improving connection strength.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Although the design of multiple annular grooves can accommodate molten slag, the molten slag may not be discharged smoothly due to insufficient depth and width of the grooves, which will affect the welding quality. Opening multiple annular grooves on the outer circumference of the connecting pipe may weaken the structural strength of the connecting pipe. Especially under high pressure or high stress environment, it may cause the connecting pipe to deform or break, reducing the efficiency of friction welding of integrated valve. Utility Model Content

A wear-resistant coating 9 is provided on one side of the outer wall of the connecting pipe 6. A support groove is formed on the inner wall of the connecting pipe 6. An annular reinforcing rib 11 is fixedly connected to the inner wall of the support groove.

[0028] Furthermore, the length of the trapezoidal threaded groove 8 is adapted to the length of the annular reinforcing rib 11, and a circular tube 4 and a circular tube 12 are provided on one side of the outer wall of the integrated valve housing 1.
