Explosion damper damper Benxi _ _ Swiss special forces air conditioning

 PYF-P-1A smoke damper characteristics: 1. Smoke damper usually was normally closed when the fire after a smoke detector signal sent by the control center input DC24V, solenoid actuator moves, the valve automatically opens, starts out smoke exhaust fan, the valve when the temperature reaches 280 When ℃, fuse action, the valve closes, serve to prevent the fire from spreading along with the duct. Manual reset the valve action. 2. Control voltage DC24V manual dampers, micro switch contact capacity AC380V, 3A, solenoid operating current of 0.3A. 3. Smoke damper control and related equipment can be interlocked. Description: PYF-P-1A (near control, NC) electric performance: make the exhaust valve is closed and connected to DC24V power is turned off and connected to a power supply is turned on, observe smoke damper valve normally closed , power explosion damper, open exhaust valve open state observed signal output signal output function is turned on so that the exhaust valve is open, use a multimeter to measure the turn signal. Open, use a multimeter to measure the open signal. Checks appliances: feeler using conventional methods of use. By using conventional methods. Dynamometer, when pulling the valve, the valve opening should have good speed when pulling the valve, the valve should have a good open rate dampers to read scale dynamometer principle. Multimeter, should be based on the form of the output signal of the valve, use a multimeter stalls. Should be based on the form of the output signal of the valve, use a multimeter stalls. Smoke damper uses (1) usually in a normally closed valve, either manually or automatically open fire, when the airflow temperature reaches 280 ℃, the temperature sensor action, the valve is closed; (2) allows the valve is closed by DC24V power; (Electric-type smoke damper) (3) or manual reset manually shut down; (4) closed DC24V electric reset; (automatic type smoke damper is suitable for manual operation inconvenient place) (5) output signal valve closed can interlock with other fire-fighting equipment. Advantages smoke damper: 1, low air leakage, airtight performance 2, the electric current consumption of small open 3, strong corrosion resistance and long service life. (Made of stainless steel type) 4, the actuator drive flexible. Feedback, interlock signal accurately proof damper damper Benxi _ _ Swiss special forces air conditioning provided by the Texas Air Conditioning Equipment Co. Swiss special forces.
