Jin Liyuan smoke damper air conditioning prices, smoke damper manufacturers, smoke damper specifications on damper, normally open, 70 degrees or 280 degrees closed, usually installed in the duct through the firewall, fires off effect, can Set the output electrical signal, the temperature exceeds 70 degrees or 280 degrees when the valve is closed, the linkage to send (up) the fan is off. Damper purposes: (1) usually was turned on, when a fire in the exhaust pipe when the flue gas temperature reaches 70/280 degrees off, and to meet the leakage amount of smoke and fire integrity requirements within a certain period of time, from the Fire Smoke Role (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 for the inconvenience local manual operation) (4) output valve closed signal can be interlocked with other fire-fighting equipment. Damper Product Features: low air leakage, airtight performance; electric open small current consumption; strong corrosion resistance and long service life. Damper types: 1. normally open normally closed smoke damper 2. 3. Remote-controlled exhaust damper smoke damper (rope control type) 4. Automatic reset type smoke damper Chen 13775715111 Contact QQ18099207 Fax: 0523-81166576 production _ Fire Fire exhaust valve exhaust valve exhaust valve factory price _ fire dampers, exhaust valves, exhaust damper, electric fire dampers, air flow control valve, electric exhaust valve exhaust damper smoke damper, fire parts, general machinery installed in the pipe exhaust system, usually was turned on, open the smoke in case of fire, smoke exhaust pipe when the internal temperature reaches 280 degrees off, and in some time to meet the leakage amount of smoke and fire integrity requirements, from smoke fire retardant effect. Main material: carbon steel, galvanized steel, stainless steel. Contents 1 Basic information? Damper Usage? Damper Advantages? Dampers Type 2 features? Damper function? Basic functions and features of a product use information damper is usually installed in the pipe mechanical exhaust system, usually was turned on, open the case of fire smoke, smoke exhaust pipe when the internal temperature reaches 280 degrees off, and to meet the leakage amount of smoke and fire integrity requirements within a certain period of time, from the effects of smoke fire retardant. Main material: carbon steel, galvanized steel, stainless steel. Contents (1) usually was turned on, when the fire inside the exhaust pipe when the flue gas temperature reaches 280 degrees close and meet the leakage amount of smoke and fire integrity requirements within a certain period of time, from smoke fire retardant effect (2) DC24V power through the valve closed; (electric type smoke damper) (3) or manual reset manually shut down; (4) closed DC24V electric reset; (automatic type smoke damper for local inconvenience manually operated) (4) the output signal of the valve is closed, interlocked with other fire-fighting equipment. Advantages a damper, low air leakage, airtight performance; 2, the electric current consumption is small open; 3, strong corrosion resistance and long service life; (made of stainless steel type) 4, the actuator drive flexible, feedback, interlock Signal accurate. 1. normally open damper type smoke damper 2. normally closed smoke damper 3. Remote control type smoke damper (rope-controlled) 4. Automatic reset type smoke damper damper 2 Features 2.1 function normally open type smoke damper functions are as follows: 2.1.1 usually was normally open state, when the fire broke out, after the control center by DC24V power output, the valve automatically closes 2.1.2 When the pipe temperature reaches 280 ℃, the fuse. control action, the valve automatically closes the valve closes 2.1.3 output signal, interlocking exhaust fan stops 2.1.4 manually shut down, manually open the normally closed type smoke damper 2.2, the following functions:... normally closed smoke damper , also known as secondary smoke damper action. 2.2.1 usually was normally closed when the fire broke out, by the control center DC24V power input, quickly open the valve. 2.2.2 output valve open signal, interlock control exhaust fan fire. 2.2.3 manually open, manual reset closed. 2.2.4 When the pipe temperature reaches 280 ℃, fuse action, the valve is closed again 2.3 remote-controlled smoke damper (rope-controlled) function as follows: 2.3.1 has a normally closed type smoke damper all the features 2.3.2 can be remotely opened manually shut 2.3.3 manual reset rope controlling the distance criteria 6m (long can be customized) 2.4 automatic reset type smoke damper function as follows: 2.4.1 usually was normally closed, fire the event, by the control center DC24V power input, the valve automatically opens. 2.4.2 when the pipe temperature reaches 280 ℃, the fuse action, the valve automatically closes. 2.4.3 can be manually turned on. After the 2.4.4 valve open, without manual reset as long as the input DC24V power, the valve can be automatically reset to its original closed position (this function is limited to the first temperature sensor is not operating, such as the action to be replaced after a temperature sensor temperature sensor can still use this feature). 2.4.5 Output valve opens signal, interlock control exhaust fan start and stop. 2.4.6 If memory alloy temperature sensors, can be used repeatedly without replacement. Functions and Features 1. DC24V input signals, current ≤0.5A, solenoid action, the valve quickly closed; (electric type smoke damper). 2, manually shut down, manual reset. 3, the output signal and the interlock valve control signal is turned on.
