Abstract

PURPOSE: To carry out properly the sprinkling of water in a distant place and to confirm whether electromotive valves respond according to the on-off command from a controll board by using the electromotive valves equipped with limit switches.
CONSTITUTION: As shown in the connection diagram, there is provided a motor equipped with limit switches instead of many solenoid valves 8 of conventional irrigation system composed of a water pump 2, a main line 3, branch lines 4, sprinklers 5, a control board 6 and solenoid valves 8. When the electromotive valves open one by one, and voltage in the direction of opening is applied to electromotive valves, an electric current flows in the direction of opening and the valves are set in the directional of the opening. When all valves open, the electric current is terminated. When voltage in a terminating from the control board is applied to the valves after the elapse of a set time, an electric current flows in the terminating direction. When all valves are shut, the electic current is switched off. There are provided detectors for voltage and current in the direction of the opening and the shutting. Sequence control can be carried out. The sprinkling condition can also be understood from the observation of an ammeter.
