When the fire is generated, the flame invades the passage, the high temperature makes the mangible molten steel melting on the gate valve, or the memory alloy causes the bend to automatically turn off the gate valve to use the channels where the channel and evacuation export are surrounded by exports.A smoke discharge fire valve is set on the smoke exhaust system pipeline to avoid high -temperature harmful smoke and dust transmission during the fire, causing the fire to spread and expand and the side effects of the poison.Where should the fire prevention valve be set?
(1) Pipeline crossing the partition wall of the evacuation exit;
(2) The pipeline crossing the wind transparent, the power distribution room of the air -conditioning system and the key or fire risk factors;
(3) The level pipelines of the vertical air duct and the level of various layers of air ducts;
(4) Pipeline crossing the sides of the seam.
The effectiveness of fire prevention valves and smoke fire prevention valves is different. Fire valves: The efficacy is fire safety. The 70 temperature circuit breaker is automatically turned off and can be connected to ventilatory air -conditioning system air ducts.Tobacco -proceed fire prevention valve: With the help of smoke, it can also automatically turn off the 70 temperature circuit breaker (fire safety) to ventilate the air -conditioning system air duct.
The above is the general setting location of the fire prevention valve
