Know the fire prevention valve
The fire valve is mainly composed of valve body and execution agency.The valve body consists of a shell, flange, blades, and leaf linkage mechanisms.The execution agency consists of a shell, blade regulation mechanism, clutch, temperature fuse, etc.The fire valve execution agency is a metal molten melting piece and a clutch mechanism to control the rotation of the blades.
Firewood valve working principle
When the temperature of the transported gas transported in the pipeline reaches the melting temperature of the molten metal sheet, it is easy to melt the melting, and the compressed spring and spring nails on the core axis quickly lay the clutch pad.There are two reversing springs that cause the leaves to be torque and rotate.It can be seen that the fire valve execution agency adopts the principle of mechanical transmission. It does not require electricity, gas and other energy sources to ensure that it can play a fire prevention role in any circumstances.
Once a fire occurs, it will often cause serious casualties and economic losses, especially air -conditioning buildings and high -rise buildings, and the loss is even more important. Therefore, it is particularly important to prevent fire prevention and smoke.Fire fire valves are provided on the ventilation and air -conditioning system, and a smoke discharge fire prevention valve is provided on the smoke exhaust pipeline. A reasonable setting of the fire prevention valve can effectively prevent the transmission of toxic high -temperature flue gas during the fire and reduce losses.
