How to adjust the use of fire valve matters needing attention

Release Time：2021-07-21

The daily inspection and adjustment of the fire damper is required to be done every day, because it is closely related to the working efficiency and service life of the fire damper. If you want to create greater value for the fire damper, please pay attention to the daily inspection and adjustment of the fire damper.
Fire damper is a kind of equipment to avoid fire extension. It is usually installed at the entrance of the fan used for both smoke exhaust system and ventilation and air conditioning system in general buildings. The fire damper is normally open. When a fire occurs, the air flow temperature in the pipeline rises to the fuse, which is easy to fuse the fire damper. When the temperature is high, the fusible sheet is fused, the core rod will be pushed by the spring, disengaging the fork plate, and the valve shaft.
Normally, if it is required to adjust the air volume, the valve opening can be adjusted through the handle linked with the valve shaft. When the requirement is reached, the position is fixed by the butterfly mother. Ring teeth are made at the touch part of the fork plate and the handle to avoid sliding after meshing, so as to keep the valve opening unchanged after adjustment.

Several advantages of our fire valve:
1. Before installing the fire damper valve, you must check whether the operating mechanism of the valve is intact and whether the action is flexible and effective.
2. The operating mechanism of the valve should have a net space of not less than 200mm on one side to facilitate maintenance. If the valve is linked with the fan, it should be equipped with a double micro switch device.
3. The fire damper can be interlocked with the ventilator and the smoke exhaust fan.
4. The fire damper shall be installed in the air duct section close to the wall or floor. The fire damper on both sides of the partition wall of the fire compartment shall not be more than 200mm from the wall surface. The pipeline and its thermal insulation material within 2.0m on both sides of the fire damper shall be made of non-fire damper combustion material.
Fire damper, fire control valve, normally open, 70 degrees closed, generally installed in the air duct through the firewall, the role of fire shutdown, you can set the output signal, smoke sense more than 70 degrees when the valve is closed, chain (supplement) fan closed.
Smoke prevention and fire prevention regulating valve is normally open and closed at 70 degrees. It is the same, but one more telecommunication signal is input and can be remotely controlled and closed by the fire control room. It is generally used in the common air duct system of air supply and air supply for fire. It can control and close rooms that do not need air supply in case of fire.
