ZPQW127 Mine smoke temperature sprinkler dust device
ZPQW127 mine smoke temperature sprinkler dust device USES: mainly used in coal mine belt transport which, on the belt, the nose and the tail inflammable parts such as sprinkler, fire extinguishing dust effect.
Characteristics: after power up, close the valve, the electric ball valve delay 6 seconds main box starting test temperature and smoke sensors. When it's one or the other has signal output or sprinkling water main box control electric ball valve open valve. When both no signal output, sprinkling water device start time delay. The delay time at 0 s - 270 - s, adjustable delay over, main box control electric ball valve close the valve. If during the period of delay, the sensor and the signal output, such as sensor signal disappears, to delay to set the time, didn't stop sprinkler.
Composition; ZP - 127 - z automatic sprinkler dust device for mine main box, GQQ0.1 mine safety type smoke sensor, GWD60 mine temperature sensor, DFH - 20/7 mine intrinsically safe electric ball valve
