fire breathing valve

< Overview of fire-proof breathing valve:
All-weather explosion-proof and fire-retardant breathing valve. This fire-proof breathing valve integrates a flame arrester and a breathing valve, and its novel structure is the first of its kind in China. It is a new type of safety equipment necessary for petrochemical storage tanks. The biggest advantage of the fire breathing valve is that it has good fire resistance and breathing performance, is light in weight and is easy to maintain. Fire breather valve is suitable for storing Class A oil products with internal point below ℃
and Class B oil products with flash point below ℃
such as gasoline, benzene, benzene, kerosene, light diesel oil, engine oil, Storage tanks for crude oil and other oil products and chemical products with the same properties use it to work normally in a temperature environment of - ℃ - ℃
.
Performance and characteristics
The shell is made of cast steel and aluminum alloy with good corrosion resistance
The corrugated fire-retardant layer is made of stainless steel with good fire-retardant performance and good corrosion resistance
Simple structure and easy maintenance Safe and convenient
Maintenance and maintenance:
In order to ensure safe use of the breathing valve, the corrugated fire-retardant layer should be removed and cleaned regularly within - months to ensure that every hole on the fire-retardant layer is unobstructed to prevent clogging and ensure safe and normal use. .
Regularly check whether the ventilation positive and negative valve discs are flexible and whether the guide rod and valve disc contact sealing surface are damaged. If damaged, replace them immediately.
During inspection, maintenance and reinstallation, it should be ensured that the joint surfaces in the valve are tightly matched with the valve disc to lift and lower flexibly.
When a new valve is put into use, the anti-vibration objects between the valve discs should be removed before installation, otherwise the breathing valve will malfunction.
