Nozzle Breather Valve

Suction Nozzle Breather Valve is an indispensable main safety equipment on the fixed roof tank of crude oil, gasoline, kerosene, light diesel oil, aromatics, etc., which can prevent evaporation loss and protect the tank from damage under over pressure or vacuum. Suction nozzle ( flame arrester ) breather valve is a safe and energy-saving product to maintain the air pressure balance of storage tank and reduce the volatilization of medium. It is a ventilation and fire resistance device installed on the fixed roof tank, which can reduce the evaporation loss of oil products, control the pressure balance of the tank and control the flame. It can automatically adjust the internal and external pressure of the tank. The breathing valve is equipped with an electrostatic protection device, which keeps the same potential with the tank body at all times. There are many kinds of breathing valve, each with its different performance and characteristics. When selecting, it is necessary to consider some objective factors according to the conditions satisfied by its characteristics and whether it can achieve good operation effect. The suction nozzle flame arresting breather valve plays a role of safety protection in the system. In practical application, its characteristic type should be selected according to the actual needs, and its diameter should be selected according to the large exhaust volume. The suction nozzle (flame arrester) breather valve is a new type of improved breathing valve, which has the double functions of collecting breathing valve and tank flame arrester. According to the national standard code for fire protection design of petrochemical enterprises (GB50160-92), "flame arrestor and breather valve shall be set for the fixed top tank of class A and B liquid storage".

The shell of the suction nozzle ( flame arrestor ) breather valve can be made of stainless steel, cast steel and aluminum alloy, with compact structure, strong fire resistance, large ventilation, small leakage, corrosion resistance, low temperature resistance, frost resistance, easy maintenance, safety and convenience; the valve disc is made of tetrafluoro carbon material, with good low temperature resistance and antifreeze performance; the fire disc is made of stainless steel, with excellent fire resistance performance.
