Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a full-automatic water supply valve with multiple water hammer prevention functions. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveying medium, such as temperature, pressure, and flow. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] During the activation process of existing valves, their actual service life is often shorter than the set service life due to long-term water impact. Especially when the valve is closed too quickly, the inertia of the pressure water flow generates a water shock wave, just like a hammer hitting, which makes the valve easily damaged. Therefore, we specially designed a fully automatic water supply valve with multiple anti-water hammer functions. Utility Model Content
