The understanding of the pneumatic valve and use fire signal

fire signal pneumatic valve is mainly used in the automatic sprinkler system, pneumatic valve or start signal when the pneumatic valve is shut down for automatic fire alarm system, automatic fire alarm system after receiving the signal according to the operation of pneumatic valve in the signal, have the effect of alarm.
fire signal butterfly pneumatic valve: purpose: ZSDF type fire signal butterfly at the top of the pneumatic valve is equipped with pneumatic valve open/close signal device, pneumatic valves are closed by mistake when % ( Fully open degree /) , electrical device output signal to the fire control center is closed. So the butterfly pneumatic valve is the best product of form a complete set of automatic fire sprinkler system. Structure characteristics and working principle: the adjustment of the pneumatic valve electrical device design at the top of the worm and worm gear drive, pneumatic valve stem and direct drive, within the precision of totally enclosed electrical and mechanical device, equipped with pneumatic valve opening machine instructions and imported electrical components and rust parts. The output signal is stable and reliable for a long time.
a electric pneumatic valve node, with signal wire leads to the control center, the signal voltage v. Pneumatic valve is opened and closed, a signal to the control center, facilitate monitoring, in addition to the electric pneumatic valve node, not much difference with ordinary pneumatic valve, signal butterfly pneumatic valve.
