Fire pneumatic valve, smoke fire pneumatic valve set points have?

fire is set on the ventilation and air conditioning system pipe pneumatic valve, smoke fire is set on the exhaust system pipe pneumatic valve, in order to prevent fire, high temperature toxic gas transport in the fire spread and toxicity. In one of the following conditions of ventilation and air conditioning system of air duct should be set fire pneumatic valve:
( ） The partition of the pipeline crossing fire zone.
( ） Pipeline crossing ventilation, air conditioning room and important or fire danger room partition wall and floor.
( ） Vertical horizontal section duct and level of each layer of duct junction
( ） Both sides of the pipeline crossing deformation cracks.
the parts of the fire prevention pneumatic valve, the temperature of the gas in the pipeline when the fire reached degrees Celsius, automatically shut down. Exhaust system of space:
( ） Set up in smoke machine room of the population, when the temperature of the flue gas is more than c smoke fire pneumatic valve can automatically shut down. Smoke ventilator should guarantee can work continuously min in degrees Celsius.
( ） In row YanZhi tube set on when the temperature of the flue gas is more than C smoke fire pneumatic valve to close on its own.
