Description

Technical Field

[0002] Water-saving irrigation valves are valves specially designed for use in agricultural or horticultural irrigation systems to effectively manage and control water usage.

[0003] Water-saving irrigation valves generally achieve water-saving effects by controlling the flow of water. When selecting a valve, an adjustable valve is generally selected. The flow is controlled by manually adjusting the opening of the valve. The wider the valve is opened, the greater the flow; otherwise, the flow is reduced. The opening of the valve is adjusted by controlling the size of the flow channel inside the valve. Generally, the size of the flow channel is controlled by a baffle or other components. However, whether the baffle or other components are used to control the size of the flow channel, the baffle or other components will be impacted when the water flows. Long-term impact may cause damage to the baffle and other components. At the same time, when the user controls and adjusts the opening of the valve, the impact on the baffle or other components will change briefly. The changing impact force may cause the valve and the connected pipe to shake. The shaking may cause the connection between the valve and the pipe to be loose, which may cause a waste of water resources. Summary of the Invention
