Abstract
A nozzle gate valve is provided in an irrigation sprinkler for quick and easy shut-off of water flow to a sprinkler spray nozzle. The gate valve is mounted within a sprinkler spray head at an upstream side of the nozzle for displacement between open and closed positions respectively permitting and preventing waterflow to the nozzle. In the preferred form, the gate valve has a generally conical shape and defines an elbow-shaped flow path movable between the open position aligned with the nozzle for normal water supply thereto, and the closed position misaligned with the spray nozzle to prevent water flow thereto. In the closed position, the spray nozzle can be removed and/or replaced, or other sprinkler adjustments can be performed, without requiring a main system water supply to be turned off.
Claims37
In an irrigation sprinkler having a sprinkler housing defining a flow passage for coupling a supply of water under pressure to a spray head having at least one spray nozzle mounted thereon for projecting the water outwardly from the sprinkler, the improvement comprising:
- a gate valve mounted along the flow passage at an upstream side of the spray nozzle, said gate valve being movable between an open position permitting substantially unobstructed water flow to said spray nozzle and a closed position preventing water flow to said spray nozzle;
- said gate valve defining an inlet, an outlet, and a flow path extending therein between said inlet and said outlet, said gate valve being rotatably supported within a valve chamber formed in said spray head at an upstream side of said spray nozzle;
- and
- an actuator mounted to said spray head and coupled to said gate valve for displacing said gate valve between said open position with said flow path aligned with said spray nozzle, and said closed position with said flow path misaligned with said spray nozzle.
An irrigation sprinkler, comprising:
- a sprinkler housing adapted for connection to a supply of water under pressure, said sprinkler housing including a pop-up riser having a spray head at an upper end thereof, and at least one spray nozzle removably mounted on said spray head for projecting water outwardly from the sprinkler;
- a gate valve mounted on said spray head at an upstream side of said spray nozzle, said gate valve being movable between an open position permitting substantially unobstructed water flow to said spray nozzle and a closed position preventing water flow to said spray nozzle;
- said gate valve defining an inlet, an outlet, and a flow path extending therein between said inlet and said outlet, said gate valve being rotatably supported within a valve chamber formed in said spray head at an upstream side of said spray nozzle;
- and
- an actuator mounted to said spray head and coupled to said gate valve for displacing said gate valve between said open position with said flow path aligned with said spray nozzle, and said closed position with said flow path misaligned with said spray nozzle.

- said gate valve defining an inlet, an outlet, and a flow path extending therein between said inlet and said outlet, said gate valve being rotatably supported within a valve chamber formed in said spray head at an upstream side of said spray nozzle;
- and
- an actuator pin rotatably mounted to said spray head and coupled to said gate valve for displacing said gate valve between said open position with said flow path aligned with said spray nozzle, and said closed position with said flow path misaligned with said spray nozzle.
