Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a high-strength automobile copper valve. Background Art

[0002] Copper valves are widely used in the pipeline system of the automotive industry due to their excellent thermal conductivity, corrosion resistance and mechanical properties. However, existing automotive copper valves have some problems in connecting to pipelines. Although threaded connections, flange connections, clamp connections, push-on connections and welding connections provide convenience and reliability to a large extent, during vehicle operation, the pipeline system is often subjected to tension and pressure from different directions. These forces may cause failure of the connection, especially under long-term vibration or extreme working conditions, such as high pressure or strong mechanical vibration.

[0003] Current copper valves may detach or lose their sealing performance when subjected to high tensile forces, especially at the end of the pipeline. Such detachment will not only cause leakage in the pipeline system, but may even cause the valve to fall off completely, affecting the safety performance and reliability of the vehicle. In view of this, we propose a high-strength automotive copper valve. Utility Model Content
