ZFQ-1 explosion-proof and flame-retardant breathing valve This product integrates flame arrester and breathing valve. Its novel structure is the first one in China. It is a necessary new type of safety equipment for petrochemical storage tanks. Its greatest advantages are good fire resistance and breathing performance, light weight and convenient maintenance. This product is suitable for the storage of Class A oils with an internal point below 28 C and Class B oils with a flash point below 60 C, such as gasoline, benzine, kerosene, light diesel oil, engine oil, crude oil and other oils with the same properties. It works normally in the temperature environment of - 35 60 C.
Performance and characteristics
1. The shell is made of cast steel and aluminum alloy with good corrosion resistance.
2. The corrugated flame retardant layer is made of stainless steel with good fire resistance and good corrosion resistance.
3, simple structure, easy maintenance, safe and convenient.
Maintenance and maintenance
1. In order to use the breathing valve safely, the corrugated flame retardant layer should be removed regularly within 3-6 months and cleaned to ensure the smooth flow of each hole in the flame retardant layer, prevent blockage and ensure safe and normal use.
