The all-weather explosion-proof breathing valve is a ventilation device installed on the fixed roof tank, which can reduce the oil evaporation loss and control the storage tank pressure. Its disc structure is air cushion membrane valve disc.
main features
The all-weather explosion-proof breathing valve has the characteristics of large ventilation and small leakage, and has static grounding wire to keep the valve and tank at equal potential.
All weather explosion-proof breathing valve has antifreeze performance and is suitable for cold areas.
Operating pressure: positive pressure: 353pa (36mmh2o), 980.7pa (100mmh2o) negative pressure: 294.2pa (30mmh2o)
The all-weather explosion-proof breathing valve is the main equipment installed on the fixed roof storage tank of crude oil, gasoline, kerosene, light diesel oil, aromatics, etc. it is a ventilation device fixed on the top of the tank, so as to keep the pressure in the tank in normal state, prevent the tank from being damaged by overpressure or vacuum, and reduce the loss of liquid volatilization in the tank. Products have single breathing valve, single suction valve breathing valve, various types of structure can be combined with flame arrester structure, can also be equipped with the required nozzle.
