Firewood valve, often open at 70 ° C or 280 ° C. Generally installed on the air duct through the firewall, the fire is turned off, and the output telecommunications sign can be set. When the temperature exceeds 70 ° C or 280 ° C, the valve is closed.The wind machine is closed.
Price of fire valve
The price of fire valve ranges from 50 to 300 yuan.

Firewood valve installation location
Fire valves should be set on the air ducts of ventilation and air regulation systems: 1 crossing the fireproof partition; 2 crossing the room partition walls and floors of ventilation and air adjustment machine rooms;Point; 4 crossing the sides of the deformed seam; 5 The horizontal pipe section of the vertical air duct and the horizontal air duct of each layer, but when the ventilation and air regulation system of each fire prevention partition in the building are independently set, the fire prevention partition isThere may be fire valves at the interchange between the horizontal air duct and the vertical tube.
Working principle of fire valve
The firewood valve is installed in the central air -conditioning airway system. The working principle is the temperature control of the molten molten alloy, and the valve is turned off with the action of gravity and the role of the spring mechanism.When the fire occurs, the flame invades the air duct, the high temperature causes the melting alloy on the valve to melt, or the memory alloy will cause a variable and cause the valve to automatically close it for the occasion of the air duct and the fireproof partition.
