ZFQ-1 explosion-proof fire-retardant breathing valve

Explosion-proof and fire-retardant breathing valve is also known as - fire-retardant breathing valve. The explosion-proof and fire-retardant function and the function of the breathing valve are integrated. Its novel structure is the first in China. It is a necessary new safety equipment for petrochemical storage tanks. Its biggest advantage is that it has good fire resistance and breathing performance, is light in weight and is easy to maintain. Explosion-proof and fire-retardant breathing valve is suitable for storing Class A oil products below ℃ and Class B oil products below ℃, such as gasoline, benzene, benzene, kerosene, light diesel, engine oil, crude oil and other oil products and chemical products with the same properties. The storage tank uses it to work normally in a temperature environment of -℃-℃.
[Performance and Features]
The all-weather explosion-proof shell is made of stainless steel, cast steel, and aluminum alloy. It has good corrosion resistance. The corrugated fire-retardant layer is made of stainless steel. It has good fire-retardant performance and good corrosion resistance. The structure is simple, easy to maintain and safe. convenient.
[Maintenance and Maintenance]
For the sake of safe use, the corrugated fire-resisting layer should be removed and cleaned regularly within - one month to ensure that every hole on the fire-resisting layer is unblocked and blocked to 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 is necessary to ensure 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.
[Installation

) should be installed at the highest point of the gas source of the storage tank to reduce material evaporation loss and to smoothly provide the most direct and largest passage to the breathing valve. Usually, vertical tanks should be installed as close as possible to the central roof of the tank. For storage tanks that require an insulation layer on the tank top, they can be installed near the ladder platform
) When two breathing valves need to be installed, they are in contact with the tank top. The center should be arranged symmetrically
) If the breathing valve is used on a nitrogen sealing tank, the connecting position of the nitrogen gas supply pipe should be far away from the breathing valve interface and inserted into the storage tank from the top of the tank. This way, the nitrogen will not be directly discharged after entering the tank to achieve nitrogen sealing. the goal of.
