Abstract
Self-contained, automated flow control system for use in a water distribution system such as a sprinkler system. The system has a master valve which controls communication between a supply line and a manifold, and a plurality of control valves which control communication between the manifold and a plurality of outlet lines. An anti-siphon valve is connected between the master valve and the control valves to prevent water from being drawn back into the supply line from the outlet lines. Operation of the master valve and control valves is controlled by a clock timer which is programmed to actuate the valves in a predetermined sequence and, in some embodiments, to open the master valve after one of the control valves is opened and to close the master valve before the control valve is closed.
Claims3
In a sprinkler control system for controlling the delivery of pressurized water from a supply line to a plurality of outlet lines connected to individual sections of a sprinkler system:
- a manifold having an inlet port and a plurality of outlet ports, a main valve connected to he inlet port for delivery of pressurized water from the supply line to the manifold, a plurality of control valves connected to respective ones of the outlet ports for controlling the delivery of pressurized water from the manifold to the outlet lines, and means for sequentially operating the master valve and the control valves in such manner that the master valve is opened after a control valve is opened and is closed before the control valve is closed.
In a sprinkler control system for controlling the delivery of pressurized water from a supply line to a plurality of outlet lines:
- a master valve adapted to be connected to the supply line, a plurality of control valves connected to the master valve and adapted to be connected to respective ones of the outlet lines, and means for sequentially operating the master valve and the control valves in such manner that a control valve is opened before the master valve is opened and the master valve is closed before the control valve is closed.
In a method of controlling the distribution of pressurized water from a supply line to a plurality of outlet lines, the steps of:
- connecting a master valve to the supply line, connecting a plurality of control valves between the master valve and respective ones of the outlet lines, opening the control valve connected to one of the outlet lines, opening the master valve after the control valve has been opened, closing the master valve, and closing the control valve after the master valve has been closed.
