In the air conditioning pipe wind and ventilation system with 1 degrees of the fire valve; usually open, closed fire, interlocking fan, the fan is closed; 2.280 degrees fire valve in the exhaust system piping, normally open, fire smoke, smoke when the temperature reached 280 degrees, the fire proof valve closed, closed interlocking fan;
3.280 fire valve should be normally open, also called high temperature fire valve, usually installed in the ventilation duct with high temperature, when the temperature reaches 2 after the fusible alloy melts, the valve closed, also can use 24V electrical signal control. If the 280 smoke fire valves should be closed, the installation of fire occurred in the exhaust pipe when the control center gives signals to open exhaust, when the temperature gets off the fusible alloy melts valve 280, a valve is two times of action.
4., the ventilation pipe is not used when the fire, to 70 degrees when the fire valve closed to prevent the spread of fire. Smoke exhaust system fire valve is smoke in the fire, smoke temperature is higher, to 280 degrees, the fire through the mechanical exhaust has not achieved the effect of smoke exhaust valve closed to prevent fans and other equipment damage.
5.70 degree fire valve often open, fire often open; in case of fire closed.
6. smoke, fire, 280 normally closed, in case of fire open, began to exhaust smoke; when the air flow to 280 closed.
7. fan description, blower = positive pressure fan = fill fan, called different, and for a variety of purposes, conveying gas temperature below 80 degrees.
8. smoke exhaust fan, used for fire smoke exhaust, requiring 280 degrees 30min running, can also be used for kitchen soot.
9. exhaust fan, a wide range of applications, conveying gas temperature below 80 degrees
10.70 degrees fire dampers and 280 degrees fire dampers and the above fan relationship, fire smoke pipe using 280 degrees fire damper, and the rest according to fire zone with 70 degrees fireproof valve
7, high regulations "smoke fire valve" and "fire valve" Regulations
First, fire class 1, fire valve: the role is fire protection, 700C temperature fuse automatically closed, linkage can be used for ventilation and air conditioning systems within the wind pipe
2. Anti smoke fire valve: depending on smoke control action, power off (smoke prevention), but also 700C temperature fuse automatically closed (fire) for ventilation and air conditioning systems within the wind pipe
Two 、 smoke exhaust
1, smoke exhaust: electric, manual or remote open, and smoke exhaust fan linkage, can be equipped with 2800C shut-off device, for smoke exhaust area of the ceiling or wall
2 、 exhaust valve: electric or manual open, and smoke exhaust fan linkage open, used for smoke exhaust system wind pipe
3, smoke fire valve: electric or manual open, 2800C fuse closed, for smoke exhaust fan suction pipe at the mouth
4, smoke window: smoke sense control action, electric switch, also can be opened at a distance, used for natural smoke exhaust on the exterior wall.
Why should the 280 degree smoke exhaust valve be closed when it is closed? This friend also told me that when the fire valve temperature reached 280 degrees, indicating that the fire has been great, the basic survival of personnel may not, and then do not stop the fan will only contribute to the fire.
