This valve is usually used with the flame arrester. The valve has the characteristics of large ventilation volume, good sealing performance, small leakage and corrosion resistance.
FQ All-weather Breather valve is a kind of tank breather valve suitable for the installation of crude oil, gasoline, kerosene and other light oil storage tanks. It uses the weight of the valve disc to control the expiratory pressure and suction vacuum in the tank. When the gas pressure in the tank exceeds the allowable value, the pressure valve will be opened to discharge the mixed oil and gas from the tank to avoid increasing the pressure; Flame Arrester When the vacuum degree in the tank exceeds the allowable value, the vacuum valve will open and inhale air to maintain the pressure balance of the oil tank and maintain stability within a certain range. Therefore, the breathing valve reduces the evaporation loss of oil products to a certain extent. The product does not require external equipment, and can be installed indoors and outdoors, adapt to four seasons, and can be used with the flame arrester. Its operating temperature range is -35℃ to 60℃, and it is mainly installed on the top of the oil storage tank under normal pressure (including micro negative pressure).
Structure and size Structure and size:
Flame arrester refers to the safety protection equipment that prevents the flame from spreading and spreading in the pipeline. Generally installed in the pipeline conveying combustible gas, or on the ventilated tank, to prevent the transmission of flame (deflagration or detonation) through the device, consisting of a fire retardant core, flame arrester shell and accessories. Flame arresters are also commonly used in pipelines carrying flammable gases.
