HXF with nozzle breathing valve is installed on the fixed tank top, which can reduce the evaporation loss of oil, control the pressure of the tank and prevent the external flame from entering. It has the characteristics of large ventilation, small leakage, corrosion resistance, etc., and has electrostatic grounding wire, which keeps the valve and tank body at equal potential. At present, in the parts where the nozzle type breathing valve is prone to generate static electricity, the technical improvement is made, and the polytetrafluoroethylene gasket is added so that the electrostatic discharge device is not needed.

working principle

HXF with nozzle breathing valve is an important accessory to protect the safety of oil tank. It is installed on the top plate of the tank, which consists of pressure valve and vacuum valve. Its function is to keep the oil tank airtight and reduce the evaporation loss to a certain extent. When necessary, it can automatically regulate the pressure inside and outside the tank, and play a safe role in the tank.

HXF with nozzle breathing valve when the oil and gas pressure in the tank is greater than the allowable pressure of the tank, the oil vapor will escape through the pressure valve, and the vacuum valve is in the closed state; when the oil and gas pressure in the tank is less than the allowable vacuum degree of the tank, the fresh air enters the tank through the vacuum valve, and the pressure valve is in the closed state, and the allowable pressure (or vacuum pressure) is controlled by the weight of the regulating plate.
