Description

Technical Field

[0001] The present invention relates to the technical field of valves, in particular to an improved angle valve. Background Art

[0002] Angle valves, also known as angled stop valves, triangular valves, or angle valves, are named because the pipes form a 90-degree angle at the angle valve. They are widely used in various applications due to their simple flow path and low flow resistance. However, conventional angle valves are fixed to the pipe fittings, making them inconvenient to connect. This can lead to forceful installation when adjusting the outlet direction, causing the valve body to break. Furthermore, after the angle valve is installed, the outlet angle often does not match the product requiring the angle valve, causing the connecting pipe to twist, which can accelerate the aging of the connecting pipe over time.

[0003] To address the aforementioned issues, Chinese patent number CN208951279U discloses a fully rotatable angle valve body, comprising an angle valve body, an inlet portion and an outlet portion, the inlet portion having an inlet hole, the outlet portion having an outlet hole communicating with the inlet hole, the inlet hole being connected to a valve core, the inlet portion having an inlet pipe rotatable 360 ​​degrees around the axis of the inlet hole and sleeved onto a movable inlet rod of the angle valve, the angle valve body and the inlet pipe being rotatable 360 ​​degrees relative to each other around the axis of the movable inlet rod, the inlet pipe being connected to the inlet hole. While the original fixed outlet portion has been modified to one that can rotate 360 ​​degrees, solving the angle connection issue of the angle valve outlet, the following issues still exist:

[0004] 1. The structure is complex and the assembly is inconvenient. Auxiliary tools are required when installing the water inlet movable rod of the angle valve, which leads to low installation efficiency and increased installation costs.

[0005] 2. The complex structure makes the manufacturing cost high. In addition, the angle valve body and the water inlet pipe must be rotated around the angle valve water inlet movable rod, which requires not only high manufacturing technology but also high matching accuracy between its parts, further increasing the manufacturing cost of the angle valve and is not conducive to the promotion of the product market.
