The figure is a typical storage tank safety device installation map. Most tanks are installed on the breathing valve, emergency relief valves (or emergency relief manholes) and gas control valve device.
Breathing valve to the pump injection / extraction medium or heat exchange conditions, to provide pressure or vacuum relief to prevent tank rupture or deflated. Emergency relief valves (or emergency relief manholes) has two functions: First, because rapid discharge of fire around the tank or exceed the design flow of media into the tank caused by overpressure; second suction valve is not normal in the regular open the case of constant pressure and suction air pressure relief (with a suction valve for the emergency relief valve is concerned). Gas control valve is a precision adjustment device by controlling the flow of the high-pressure gas tanks to keep a low gas pressure, and when the media is out of the tank or tank gas pressure to reduce the release of heat to keep the tank pressure . Flame arrester function is to prevent the flame in the gas transmission pipeline system to protect the storage of flammable medium low pressure tank. It can prevent the spread of external heat and flame to protect the tank low flash point of the medium, thereby enhancing the tank's fire performance and safety. Typically, the atmosphere will be exported through the flame arrester breather valve installed in the top.
