Classification of fire valve:
1. The fire -proof valve of the smoke -proof system, open and off, turn off at 70 degrees, but one more communication equipment number is tightened, which can be turned off by remote operation of the consumer control room.In the software, a house that can be manipulated during a fire accident can be manipulated;
2. Fire valve of the opening and turning smoke exhaust system, 280 degrees fuse off, open and off, output communication equipment number, this type is similar to 1, only the melting temperature is different, the temperature of the smoke and dust exceeds 280 degrees, it is fully fused and closed.Connecting the fire fire exhaust fan.
1. Fire fire valve of the normal closed smoke exhaust system (normal closed, communication equipment number is opened, 280 degrees of melting off, or manual shutdown) is generally used in the smoke -proof system, which can be used in fire to smoke to smoke and install one.The control room is opened during the accident, and the fire smoke exhaust fan can also be turned off when closed.
2. Tobacco discharge valve, various departments are called differently, some are called smoke exhaust valves based on its posture temperature, and some are based on its main use characteristics as the fire prevention valve, but for the machine and equipmentMetal materials are replaced by the 280 -degree melt.
3. Fire fire valve (for engineering projects for subway stations), the natural ventilation of the underground railway, the fire prevention of the air -conditioning unit, and the smoke exhaust valve have the functions of the full automatic alarm system with the fire accident and the continuous operation of the gas fire extinguishing system software.
If you have been installing a smoke exhaust valve on the pipeline, you can use a general single -sided shutter air outlet; otherwise you need to use a plate -type smoke exhaust port, which also contains the tissue of the fire valve of the smoke exhaust system.
Installation of the fire valve:
The fire prevention valve is installed in the home air -conditioning duct system software. The principle is that it is very easy to molten the temperature of the aluminum alloy. The effect of using the effect of the effect and the effect of the bomb yellow tissue is used to close the valve.When the fire accident occurs, the flame invades the air ducts, and the high temperature causes the easy melting aluminum aluminum in the valve, or the deformation of the shape memory alloys will be automatically closed automatically, and the air ducts and evacuation exports are surrounded by exports.
The key point of fire valve is used:
1. The key parameters of the fire prevention valve are specified models.
2. Firewood valve is suitable for ventilation and air -conditioning engineering system software. Except for the fire valve of the kitchen exhaust smoke system software of commercial buildings, the posture temperature is 150 ° C. Generally, the temperature of the fire valve of the ventilation air -conditioning engineering system software is 70 ° C.
3. Firewood valve is suitable for natural ventilation, air conditioning or smoke -proof system.
4. Pay attention to the effect of valve when using valve. It is necessary to open or automatically close, automatically closely closed, manually close, manual calibration, signal output, long -distance manipulation, etc.
5. If the valve is connected to the centrifugal fan, you should take a double -dial switching device.
The leaves of the oil circuit board should be thick steel plates, which are thin and thick. The oil circuit board is made of difficulties. The rotating component should be used for corrosive metal composite materials and rotating the spiritual stool.The thickness of the valve should not be lower than 3mm.Yi Rong components should be based on the recognition specifications of the fire unit.
