Details of FH-type damper series: fire damper series of automatic fire damper ZFFH-1 SFDW 70 ℃ automatically shut down, the electrical signal DC24V closed manually shut down, automatic reset, 0 ° -90 ° five speed adjustment, output off electrical signals. NOTE: Letter Meaning: Type the first letter of the product name group Pinyin Abbreviation: P- row Y- H- fire prevention smoke F- F- valve K- port model of the second set of numbers for the product design number, the third set of figures for the control location of bodies, I type the control mechanism on the left side, II is on top of the control function symbolic significance, S- action on behalf of the electromagnet F- temperature fuse action V- air volume control B- D- manually reset remotely operated fire vent FHK-1 air control valve by the fire dampers and a thin aluminum outlet combination for the inlet and return air inlet duct fire safety requirements of ventilation and air conditioning systems, usually mounted on the side duct or duct end and into the wall, usually the style of port to use, adjustable air flow direction, its dampers may be in the range 0 ° -90 ° stepless adjustment, when the fire broke out on a sheet of fusible valve 70 ° operation, the valve closed, cut off the fire and the wind spread along the flue pipe. Performance: 1 can be used to adjust the airflow direction style mouth. 2.70 ℃ when the valve is closed 3. manually stepless adjusted within the range of 0 ° -90 °. The manual reset. Principle of operation means: manual rotation adjustment lever, adjust the valve opening is not within 0 ° -90 ° range, the air temperature to 70 ℃, when. Reset when the valve is closed, the first off downwind exchange new fusible sheet, and then adjust the valve opening degree, and put on air. Fire control valve FFH-2FVD FFH-7FVD apply: fire control valve is usually installed in the air-conditioning system, usually always open, in case of fire, fuse action and close the valve, the valve blade may be in the 0 ° ~ 90 ° V file adjustment. Performance: temperature 70 ℃, fuse action, the valve closes. Manually shut down, manually reset. Manually changing the opening angle of the blades. Telecommunications number issued after the close. Note: fire control valve FFH-2FVD shape and FFH-1, as fire control valve FFH-7FVD the same shape and FFH-6. Smoke fire control valve FFH-3SFVD FFH-8SFVD apply: mounted on the return air duct air-conditioning systems, usually was turned on, when the fire broke out, when the pipeline gas temperature reaches 70 ℃ closed, since smoke fire retardant , five-speed valve blade can be adjusted within the 0 ° ~ 90 °. Performance: manual reset mode. Manually changing the opening angle of the blade, telecommunications No. DC24V through smoke, temperature sense back into the control center the valve closed. Telecommunications number issued after the close. Convenient temperature fuse replacement. Valve various components were carried out embalmed. NOTE: FFH-3SFVD the same shape and FFH-1, FFH-8SFVD the same shape and FFH-6. Small fire control valve FFH-4FVD-5FVD applicable: Small fire control valve is usually installed in the ventilation duct small area of ??ventilation and air conditioning systems, usually always open, 70 ℃ when the valve is closed to prevent the fire spread, the valve blade in 0 ° stepless adjustment within ~ 90 °. Performance: temperature 70 ℃, the temperature sensor is activated valve closed. Manually shut down, manually reset. Manual adjustment valve angle. Close the valve output electrical signal. Automatic smoke dampers ZFFH-1 SFDW Scope: 1. there is smoke on the fire safety requirements applied to air conditioning system piping, especially for building equipment flammable gas fire extinguishing system, because when the fire needs to close all the valves , promptly after opening fire ventilation valve is completed. 2. For air conditioning ducts installed in the ceiling, can not be manually reset occasions. Performance: 1 valve usually always open, DC24V power output by the control center of the valve automatically close the valve, and can interlock ventilation, air-conditioning fan is stopped, the output signal is turned off. 2.70 ℃ fuse action when the valve is closed .3. Press the manual button actuator valve closes. 4. When required the valve is opened, the electrical signal DC24V can automatically reset the valve to the open state and interlock reset torque 12N.m ventilation and air conditioning fan automatically starts .5 central control center control valve can be, but also automatic control unit. 6. The mechanism is provided with a torque adjusting device can be adjusted according to the specifications of dampers operating torque to ensure the reliability of action, action in three torque block, weak IN.m in 1.5NM strong 3N.m7. The above mechanism capable of adjusting device Binning adjusting the valve opening angle of the blades, the grade is divided into 15 °, 22.5 °, 30 °, 37.5 °, 45 °, 60 °, 90 °. Automatic smoke dampers operating unit principle vane opening adjustment handle clockwise to reset position, disengage the handle and adjust the board holding the lock and turn the adjustment plate and angle as shown in the retention lock, and then handle the adjustment plate locking blade opening angle is the desired angle. Close the valve when the control center DC24V power output, connected to the terminals on the actuator, 1 +, 2 +, solenoid pull, even the automatic locking mechanism is actuated, so that the locking mechanism is disengaged hook closure valve spindle, valves In spring force, counterclockwise, quickly closed, end bodies with a manual button to manually press the button in the direction shown in the figure to achieve the same valve is closed when the air flow temperature 70 ℃, dissolved breaker off arm in spring under force, along the clockwise rotation of the spindle lock is disengaged the hook and fixed, the valve closes. Valve Reset When DC24V current is turned on, the terminals on the actuator 4 +, 2, motor movements, through the transmission mechanism and rocker mechanism, drive shaft clockwise reset. When reset to a predetermined position, the micro switch off the motor rotation is stopped. Such as manual reset adjustment, just turn the handle clockwise, the spindle engages the hook with the locking mechanism can be. The same way as the fusible rod replacement methods and fire control valve, the valve before resetting need to exchange the fusible rod loaded arm resealed so the rod core, or can not be reset action. When the Fire and Smoke systems all use tobacco (temperature) sensor and control center control damper when that body temperature fuse can not, then can realize remote control and automatic shut reset operation.
