Abstract
PURPOSE: To facilitate the use of an installation and enhance durability thereof as well as to enable to supply liquid economically by converting an electric signal due to one three-core cable to an air signal successively by each electricity- air pressure conversion relays to operate an air operating valve.
CONSTITUTION: In an electricity-air pressure conversion relay unit 1, intermittent operation of application voltage added to terminals 1, 2 of an input terminal 109 from a control apparatus 3 through a three-core cable 4 is repeated. In synchronization with the repeating numbers, the NO1WNOn units 1 are successively switched. In the operated unit 1, power is supplied to solenoid coil of an air operating three-way solenoid valve 100 and a primary side inlet a and a secondary side outlet (b) are communicated. Air output due to this operation operates the air operating valve 2 and water or a chemical liquid from a fluid pipe channel 7 is supplied to a sprinkler 10 of a water scattering pipeline 9. When predetermined liquid supply is finished, voltage is applied between the terminal of the input terminal 109 and a reset terminal 3 in the unit 1 and each units 1 are returned to an original condition.
