Flame Retardant With Discharge Nozzle Breathing Valve
Breathing valve is a kind of air breather which install on the petrochemical fixed storage tank, in order to avoid tank over the pressure or vacuum making the storage tank destruct, prevent the outside flame enter, reduce the tank fluid volatile.
According to the national standard of "petroleum chemical enterprise design specification for fire" (GB50160-92) Regulations: "fixed roof tank Chu Cunjia, B liquid, flame arrester should be located and breathing valve".
Take out take (fire) breathing valve type HXF-HJ/HJZ is the main safety equipment for crude oil, gasoline, kerosene, indispensable light diesel, aromatics and other fixed roof storage tank, is to prevent the evaporation loss and protect the tank overpressure or vacuum in the subject effect from destruction.
Take out take (fire) breathing valve is the maintenance of tank pressure balance, reduce safety energy-saving products medium volatile.
Take out take (fire) breathing valve HXF-HJ/HJZ type ventilation and fire retardant device installed in the fixed roof tank, can rise to reduce the evaporation loss, control the tank pressure balance control and flame interaction.
It can carry out the features of automatic adjustment on tank inside and outside pressure.
Take out take (fire) breathing valve type HXF-HJ/HJZ is one of the most popular products, with exhale take over (fire) breathing valve in the system play a security role.
In practical application, its characteristics should be selected according to the type of the actual needs, and based on the maximum discharge capacity to choose their path is the best scheme.
