Broken sprinkler flow restriction or flow shut off suppressor for sprinkler

A sprinkler for use in an irrigation system comprising:

• a cylindrical body;
• a riser mounted in the body to move upward and downward therein;
• an inlet formed in a bottom of the cylindrical body configured and operable for connection to a water supply;
• and
• a restriction valve positioned in the inlet and operable to move between an open position in which water is supplied to the sprinkler and a closed position in which the flow of water entering the sprinkler is restricted, the restriction valve comprise:
• a valve body integrated into the body of the sprinkler adjacent to the inlet and including a central opening through which water flows into the sprinkler;
• a rib extending from the valve body along a longitudinal axis of the valve at a location beyond an inner margin of the central opening;
• a valve member configured and operative to cooperate with the central opening to move between the open position and the closed position, the valve member further having a disk with a maximum diameter, the disk shaped to fit into the central opening in the valve body when the valve member is in the closed position, wherein the maximum diameter of the disk is less than that of the central opening such that the flow of water into the sprinkler is restricted;
• and
• a resilient member which biases the restriction valve in the open position until a predetermined pressure is applied to the restriction valve to move it to the closed position and to restrict the flow of water into the sprinkler body, the predetermined pressure selected based on a relative position of the sprinkler in the irrigation system,
• wherein the valve member further includes a valve stem extending downwardly from the valve member, and positioned and configured to be movably supported in a guide ring formed at a lower end of the rib, wherein the valve stem, is movable vertically to move the valve member to its open and closed positions;
• and
• the resilient member biasing the valve stem such that the valve member remains in the open position until water pressure pushing against the valve member reaches the predetermined pressure to overcome the bias of the resilient member.

• a valve member configured and operative to cooperate with the central opening to open and close the valve;
• an external thread positioned on an outer periphery of the valve body and configured and operable to screw the restriction valve into the sprinkler body;
• and
• a resilient member which biases the restriction valve in the open position until a predetermined pressure is applied to the restriction valve to move it to the closed position and to restrict the flow of water into the sprinkler body, the predetermined pressure selected based on a relative position of the sprinkler in the irrigation system,
• wherein the valve member further includes a valve stem extending in a direct of a longitudinal axis of the valve from the valve member, and positioned and configured to be movably supported in a guide ring formed at a lower end of the rib, wherein the valve stem, is movable vertically to move the valve member to its open and closed positions;
• the resilient member biasing the valve stem such that the valve member remains in the open position until water pressure pushing against the valve member reaches the predetermined pressure to overcome the bias of the resilient member, and
• the resilient member is tensioned to resist compression until the predetermined pressure is exceeded, the predetermined pressure is selected based on a relative position elevation of the sprinkler irrigation system.
