Abstract
Official abstract text for this publication.
A method of operating a drip irrigation system is provided and includes providing drip irrigation lines aside a diverter line with T-junctions interleaved between adjacent ones of the drip irrigation lines and each T-junction including a three-way line coupled to the diverter line, a check valve operably disposable between the three-way line and a downstream end of an upstream one of the drip irrigation lines to permit fluid flow in only a forward direction and a controllable valve operably disposable between the three-way line and an upstream end of a downstream one of the drip irrigation lines.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a drip irrigation system, the method comprising: providing drip irrigation lines aside a diverter line with T-junctions interleaved between adjacent ones of the drip irrigation lines and each T-junction comprising: a three-way line coupled to the diverter line; a check valve operably disposable between the three-way line and a downstream end of an upstream one of the drip irrigation lines to permit fluid flow in only a forward direction from the downstream end of the upstream one of the drip irrigation lines to each leg of the three-way line; and a controllable valve operably disposable between the three-way line and an upstream end of a downstream one of the drip irrigation lines; opening each of the controllable valves to permit fluid flow in only the forward direction from each leg of the three-way line to an upstream end of a downstream one of the drip irrigation lines; and closing each of the controllable valves to prevent the fluid flow. 2. The method according to claim 1 , wherein the opening and closing is in accordance with a predefined schedule. 3. The method according to claim 2 , wherein the predefined schedule is defined in accordance with a predefined temporal resolution. 4. The method according to claim 1 , wherein the opening and closing is in accordance with current atmospheric conditions. 5. A method of operating a drip irrigation system, the method comprising: providing drip irrigation lines aside a diverter line; interleaving T-junctions between adjacent drip irrigation lines with each T-junction comprising: a three-way diverter line coupling; a check valve operably disposable between the three-way diverter line coupling and a downstream end of an upstream one of the drip irrigation lines to permit fluid flow in only a forward direction from the downstream end of the upstream one of the drip irrigation lines to each leg of the three-way line; and a controllable valve operably disposable between the three-way diverter line coupling and an upstream end of a downstream one of the drip irrigation lines from each leg of the three-way line to an upstream end of a downstream one of the drip irrigation lines; and opening each of the controllable valves of each of the T-junctions to permit fluid flow in only the forward direction from each leg of the three-way line to an upstream end of a downstream one of the drip irrigation lines; and closing each of the controllable valves to prevent the fluid flow. 6. The method according to claim 5 , wherein the opening and closing is in accordance with a predefined schedule. 7. The method according to claim 6 , wherein the predefined schedule is defined in accordance with a predefined temporal resolution. 8. The method according to claim 5 , wherein the opening and closing is in accordance with current atmospheric conditions.
