All-weather fire retardant valve principle
| Document.write('') ​​The valve.write('') ​​is a type of document.write('') ​​safety valve document.write(''), which is a ventilation device fixed to the top of the tank to Ensure the normal state of the tank pressure, prevent overpressure or over-vacuum in the tank, damage the tank, it can also reduce the loss of liquid volatilization. This valve is usually used with the flame arrester. According to the national (Petrochemical Design Fire Protection Code) (GB50160-92): "A fixed liquid tank of Class A and B liquids should be provided with document.write('') ​​flame arrester document.write('') ​​and document.write ('') Breathing valve document.write('') ". Document.write('') ​​All-weather fire retardant valve document.write('') is a new type of safety equipment necessary for petrochemical storage tanks. Its great advantage is that it has good fire resistance, light weight and convenient maintenance. It is suitable for Class A oils with a flash point below 28 ° C and Class B oil with a flash point below 60 ° C. Such as gasoline, kerosene, diesel, crude oil, benzene, toluene, ethanol and other medium storage tanks, it works normally in the temperature environment of -35 ° C - +60 ° C. Document.write('') ​​The all-weather fire breathing valve document.write('') ​​is used to install the main safety equipment on fixed top tanks such as crude oil, gasoline, kerosene, light diesel oil, and aromatics. It is used for evaporation loss and protection of the tank from damage during overpressure or vacuum. It also has the characteristics of large ventilation, good sealing performance, small leakage and corrosion resistance. Operating pressure: |
