Leak Stopping Sprinkler Heads

Field of Invention

This invention relates to the field of water conservation and more specifically to lawn irrigation sprinkler heads designed to prevent water loss should the sprinkler head be damaged.


A leak stopping sprinkler head includes a hollow body that has an upper portion and a lower portion fluidly connected to a valve body. The upper portion has a spraying nozzle and a first internal diameter. The lower portion has a second, larger internal diameter. The valve body includes a valve seat fluidly connected to the lower portion and a water supply. A hollow spheroid is larger than the first diameter, smaller than the second diameter and has perforations for passage of water. A rigid rod connects the spheroid and a sealing disk for the valve seat. The rod is sized to hold the disk away from the valve seat when the hollow body is intact. Destruction of the hollow body permits the spheroid to move out of the hollow body, pulling the rod and the disk upwardly, causing the disk to seal the valve, stopping the flow of water.
