Daily Maintenance Of All-weather Group Or Breathing Valve

Sep 28, 2019

Breathing valve is a kind of safety valve. It is a ventilation device fixed on the top of the tank to ensure the normal state of the tank pressure, prevent the overpressure or ultra-vacuum in the tank, and damage the tank. It can also reduce the liquid volatilization loss. This valve is usually used with the arrester.

 

All-weather fire resistance breathing valve is a necessary new type of breathing valve safety equipment for petrochemical storage tanks. All-weather fire resistance breathing valve has the advantages of good fire resistance breathing performance, light weight and convenient maintenance. The suitable flash point of all-weather fire resistance breathing valve is less than 28 ℃ for Class A oil and 60 ℃ for Class B oil. Such as gasoline, kerosene, diesel oil, crude oil, benzene, toluene, ethanol and other medium storage tanks, it works normally in the temperature environment of-35 ℃-60 ℃.

 

All-weather fire resistance breathing valve is used to install the main breathing valve safety equipment on crude oil, gasoline, kerosene, light diesel oil, aromatics and other fixed top storage tanks. All-weather fire resistance breathing valve plays the role of evaporation loss and protection against damage of storage tank under overpressure or vacuum. All-weather fire resistance breathing valve also has the characteristics of large ventilation, good sealing performance, small leakage, corrosion resistance and so on.
