Smoke fire the main functions of the pneumatic valve and advantages

smoke fire pneumatic valve in play an important protective role when the fire broke out, so its safety and high temperature resistant performance is better. So you know about the what? Follow below small make up a brief understanding its main functions and the related advantages. The smoke fire DCV pneumatic valve input electric signal, agile electromagnet action, pneumatic valve open; Open closed manually, manual reset; Pneumatic valve open closed signal output and interlock control signal; ° ~ ° manual control within the scope of blade open degree; （ Regulate type) 。 Its main advantages are:. Low leakage air volume, good airtight function; 。 Small electric open cost current; 。 Strong corrosion function, long using life; 。 Actuator drive sensitive reaction, interlocking signal accurately.
normally closed type pneumatic valve, smoke fire and smoke fire pneumatic valve secondary action. The normally closed status at ordinary times, when the fire broke out, by input DCV power control center, pneumatic valve quickly open. Open the output signal, interlock control fire smoke exhaust fan. Manual open, manual reset shut down. When the pipeline ℃ temperature is reached, fuse action, pneumatic valve to close.
remote control type pneumatic valve (smoke fire Rope type control) Function as follows: with a normally closed type smoke fire all the features of pneumatic valve can open, manual reset manually over a long distance. The steel rope control distance standard is m ( Super-long customizable automatic reset pneumatic valve type smoke fire prevention function is as follows: the normally closed status at ordinary times, when the fire broke out, by input DCV power control center, pneumatic valve automatically open. When the pipe temperature reaches ℃, fuse, pneumatic valve automatically shut down. Manual and open it. Pneumatic valve opens, no need 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 is not the smoke fire DCV pneumatic valve input electric signal, electromagnet agile movements, pneumatic valve open; Open closed manually, manual reset; Pneumatic valve open closed signal output and interlock control signal; ° ~ ° manual control within the scope of blade open degree; （ Regulate type) 。 Its main advantages are:. Low leakage air volume, good airtight function; 。 Small electric open cost current; 。 Strong corrosion function, long using life; 。 Actuator drive sensitive reaction, interlocking signal accurately.
