Fire arresting breather valve with exhalation pipe BF4 alcohol storage tank breather valve

 
 
summary
  Hxf4 flame arresting breather valve with exhalation pipe is a ventilation device installed on the fixed roof tank, which can reduce the evaporation loss of oil products, control the pressure of storage tank and prevent the introduction of external flame
It has the characteristics of large ventilation, small leakage, corrosion resistance and static The electric grounding wire keeps the valve and the tank equipotential
At present, in the parts where the nozzle breathing valve is prone to static electricity, technical improvements have been made and Teflon gaskets have been added, so there is no need to connect the electrostatic discharge device
It is suitable for storing class a oil products with flash point less than 28 ℃ and class B oil products with flash point less than 60 ℃, such as gasoline, benzene, kerosene, light diesel, thick oil and other oil products and chemical product storage tanks with the same properties

  Structure and working principle hxf4 fire stop breathing valve with exhalation pipe is an important accessory to protect the safety of oil tank
It is installed on the top plate of oil tank and is composed of pressure valve and vacuum valve
Its function is to maintain the tightness of the oil tank and reduce the evaporation loss of oil to a certain extent
When necessary, it can automatically ventilate, adjust and balance the internal and external pressure of the oil tank, which plays a safe role in the oil tank

  When the oil and gas pressure in the tank is greater than the allowable pressure of the tank, the oil vapor escapes through the pressure valve, and the vacuum valve is closed at this time; When the oil-gas pressure in the tank is less than the allowable vacuum of the tank, fresh air enters the tank through the vacuum valve
At this time, the pressure valve is closed, and the allowable pressure (or vacuum pressure) is controlled by the weight of the regulating disc
