Wireless irrigation control |
摘要 |
A control valve has an inlet, a first outlet and a second outlet. The control valve includes a poppet valve to selectably close one of the first outlet and the second outlet. A pair of diaphragms move from a first position to a second position when fluid is supplied to the control valve to permit the poppet valve to close the first passage when fluid is removed from the control valve. A magnet operably couples a wireless transmitter to a power source when fluid is supplied to the control valve. The wireless transmitter may send a signal to terminate irrigation by the control valve when the control valve is one of a plurality of control valves connected serially to a master valve only by a fluid supply line. |
