Description

Technical Field

[0001] This utility model relates to the field of water valve structure, and in particular to a long-pipe mixing valve structure. Background Technology

[0002] Traditional mechanical hot and cold water mixing valves regulate the water temperature by mixing hot and cold water and adjusting the ratio, greatly facilitating people's lives. They are widely used in bathing and heating accessories. They are mainly composed of an outer shell and an internal mixing valve core. In some applications, such as faucets in higher positions, a longer mixing pipe valve is required. Its inlet pipe is longer, and the valve sleeve and the outside of the inlet pipe are usually equipped with a long sleeve. In order to save materials during production, the sleeve is usually made thinner. The parts that are frequently subjected to stress are prone to deformation, making it difficult to disassemble later and resulting in poor resistance to deformation. Utility Model Content
