Irrigation system

摘要

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.

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 a downstream end of an upstream one of the drip irrigation lines to first, second and third legs of the three-way line; anda 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 of each T-junction to permit fluid flow in only the forward direction from the first, second and third legs 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 of each T-junction to prevent the fluid flow in only the forward direction from the first, second and third legs of the three-way line to the upstream end of the downstream one of the drip irrigation lines.
