Parsing all types of exhaust smoke fire pneumatic valve different function

smoke fire pneumatic valve type has the following several types: normally open type pneumatic valve, smoke fire normally closed type pneumatic valve, smoke fire remote control type pneumatic valve, smoke fire Steel rope control, automatic reset smoke fire pneumatic valve.
all kinds of smoke fire pneumatic valve features as follows:
a, normally open type smoke fire pneumatic valve features:
, a normally open state, at ordinary times, when the fire broke out after DCV power output by the control center, pneumatic valve automatically shut down.
, when the temperature of the pipeline reaches ℃, fuse, pneumatic valve automatically shut down.
and output pneumatic signal valve is closed, interlocking exhaust fan to stop.
and closed manual, manual open.
2, normally closed type pneumatic valve, smoke fire or secondary action smoke fire pneumatic valve features:
in normally closed state, at ordinary times, when the fire broke out, by input DCV power control center, pneumatic valve quickly open.
signal, output of pneumatic valve is opened, the interlock control fire smoke exhaust fan.
, manual open, shut the manual reset.
, when the temperature of the pipeline reaches ℃, fuse, pneumatic valve to close.
3, remote control type pneumatic valve (smoke fire Rope type control) Features:
, a normally closed type smoke fire
all pneumatic valve function, which can be manually opened, manual reset closed at.
, steel rope distance control standard for m ( Super-long customizable
4, automatic reset type smoke fire pneumatic valve
in normally closed state, at ordinary times, when the fire broke out, by input DCV power control center, pneumatic valve automatically open.
, when pipe temperature reaches ℃, fuse, pneumatic valve automatically shut down.
and can be opened manually.
after open, pneumatic valve, manual reset, just enter DCV power supply, pneumatic valve can be automatically reset to the original closed position ( This feature is limited to the temperature sensor before action, such as temperature sensor movement need to change the temperature sensor to be able to use this feature.
signal, output of pneumatic valve is opened, the interlock control exhaust fan stop.
, if the temperature sensor, memory alloy can be used over and over again, without replacement.
