After the valve is opened without manual reset, simply enter DC24V power, the valve can be automatically reset to its original closed position (this feature is limited to the first temperature sensor is not operating, such as temperature sensors need to be replaced after the operation temperature sensors can still use this feature) .2.4.5 output valve open signal, interlock control exhaust fan start and stop .2.4.6 If memory alloy temperature sensor, can be used repeatedly without having to replace the functions and features 1, the input DC24V electrical fire damper production, current ≤ 0.5A, solenoid action, quickly close the valve; (electric type smoke damper). 2, manually shut down, manually reset. 3, the output signal of the valve open and interlock control signal factory production equipment, advanced manufacturing technology, detection means complete damper effect, a higher strength of independent research and development and innovation, the main products are: air conditioning units, VAV air conditioner , damper actuators, insulation hose, fire damper, smoke fire damper, high-temperature exhaust fan, fire temperature exhaust machine, fire (ventilation) tank chassis ventilation centrifugal, plenum, axial fan, fan coil , aluminum outlet, ventilation hoses, plastic hose (snakeskin tube), and other air-conditioning end products. Dampers (70 ℃, 280 ℃) otherwise: Fire and smoke dampers regulating valve plate discharges leafy exhaust port outlet pressure delivery outlet fire leafy outlet pressure delivery outlet outlet pressure 1 principle, use damper is adjusted on the basis of the valve to increase the temperature control device. In an open state, when the fire broke out, manual, automatic temperature fuse quickly close the valve, manual reset pull open the valve. Mounted on the fire safety requirements have ventilation, air-conditioning system piping. 2, the operating principle of the usual means, fuses stuck valve stem tip axis (blade shaft) on the fork, so that the valve is normally open state. After the fire, the temperature rose to fuse the pipeline gas flow damper wholesale easily blown when the temperature fusible sheet fuse, namely spring stem pushed off the split plate, the valve shaft is rotated by the torsion spring to close the valve. Usually, for adjusting the air volume can be adjusted by the valve opening and valve shaft damper (blade shaft) linkage handle, fix the position reached by the female butterfly requirements. Fork plate with the handle at the contact is formed with a ring gear, to prevent sliding rear engaging to keep the valve opening rate set unchanged. According to user requests for additional closed electrical output means (cam, micro-switches, terminals, etc.) become fire control valve. 3. Installation Notes: installation should pay attention to the direction of airflow, so the fuse first contact with the hot gas to the blade axis. At reset, the first royal top hat, pull out the fuse. Dress fusible sheet, installed fuse. So that the stem tip insert fork, then it is set valve opening.
