Usually used to install a new staircase in the front room floor, the exhaust shaft wall, can also be installed in the exhaust system pipes or air terminal side. The main functions and characteristics usually normally closed, electric, manual open. Output ON start signal. Manual reset off. 280 ℃ temperature sensor movement, the valve is closed again. Using thin body and narrow operating box size, increase the effective area of ??the ventilation exhaust. The main technical parameters: Operating voltage / current: DC24V/0.5A. Amount of air leakage: 290m3/m2 · h ≤ 700 (pressure 1000Pa time). Temperature sensor operating temperature of 280 ℃. The main structural components: body, valves, bushings, thin actuators, grille panel. B size ≥ 800, the assembly of two actuators. Size (A × B × L) rectangle: 400 × 400 × 150 ~ 2000 × 1250 × 150 multi-leaf smoke vents apply: multi-leaf exhaust port is usually installed on the aisle side wall of the room with no windows or exhaust system, usually normally closed. When a fire occurs, smoke detector alarm signals emitted, the control center through the exhaust port DC24V power control mechanism to enable rapid open for smoke exhaust port can also be opened manually remote control, remote control manual reset. (Ⅰ and type Ⅱ type differences and PYK-3 the same) as shown: (A +250) × B type Ⅰ, A × (B +250) type Ⅱ, aluminum outlet blade parallel to the A size. Performance: · Telecommunications No. DC24V ± 2.4V to exhaust port open. · Distance manually open. · Distance manually reset. ? When the exhaust port to open the output electrical signal · according to user requirements can be interlocked with other devices. Remote control multi-leaf smoke vents installed on the aisle or the front room and smoke room without windows exhaust system. Remote control outlet pressure mounted smoke front room, the front room when the fire broke formation of positive pressure. Can be controlled in the room. Using BSD control devices, power DC24V, 0.5A. Usually normally closed, when an electrical signal to the control center DC24V open. Distance manually open, remote manual reset. After the valve actuation signal outputs open. You can interlock with other devices based on user demand. Exhaust port plate Features: BSD control devices, power DC24V, 0.5A. Usually normally closed, when an electrical signal to the control center DC24V open. Distance manually open, remote manual reset. After the valve actuation signal outputs open. You can interlock with other devices based on user demand. Scope: slab applicable to fire smoke exhaust port inlet pipes can also be used to smoke outlet pressure. You can open the remote control. Other notes: Please indicate the name of the desired valve, type, function code, specifications, and fusing temperature control device location code when ordering. Under normal circumstances the valve coating gray hammer paint, if the user requests otherwise please specify when ordering. Other specification different technical requirements, please specify when ordering. Performance tables usually was normally closed, smoke detector electrical signal sent (DC24V) by the control center when the fire, the solenoid is energized actions performed within the organization, the valve automatically opens, and the output turns electrical signals. PYK-DY remote valves can be opened manually. After the manual reset valve action (PYK-DY type of remote manual reset). Technical Parameters air volume (pressure 300Pa): ≤ 700m3/m2.h control voltage: DC24V micro switch contact capacity: AC 380V 3A full drag coefficient: <0.5 fuse operating temperature: 280 ℃ structure of the main components: body, valve leaves, shafts, bushings, check the mouth, making the actuator maximum size 800 * 800 (WXH) PYK-DY-type wire rope length does not exceed 6 meters of the company's main products are: 1, FP series fan coil ---- - machine and scroll, wind wheel, and so the whole condensate tray accessories. 2, ZK series modular air conditioning units, BFP series VAV units, new air unit. 3, FK series aluminum outlet, casual flow; DUP series of spherical vents, DUT series of spherical adjustable vents, VDP series swirl diffusers, BLP series changed manifold outlet. 4, dampers, exhaust valves, fire valves, exhaust port, outlet, air flow control valve, damper actuator valve actuator. 5, damping hook, shock absorber damping devices. 6, various muffler, silencer elbow, silencer duct, plenum chamber muffler blinds. 7, fire temperature exhaust fan, Francis fan, dual-tank fire ventilation centrifugal fans, axial fans, induced fan, mixed flow fan, wind chassis and other products. 8, energy efficient new wind ventilators, dust purification equipment. 9, the major air conditioning manufacturers supporting a variety of table cold, heaters, humidifiers, air curtain, air curtain, air conditioning and other accessories flap. 10, to undertake the entire central air conditioning design, manufacture, installation, repair, maintenance and technical advice.
