Dustproof Breathing Valve with Flame Arrester
The breathing valve is connected with storage tank arrester and used together,It can not only balance the pressure inside and outside the tank, but also prevent the explosion.
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.It is maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use ofprinciples of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work.
Pipe flame arrestor is a safety device used to prevent the spread of flammable gases and liquids from spreading and to prevent a backfire.And it is suitable for storage tank of class A oil with flash point less than 28 and Class B oil with flash point less than 60, such as gasoline, kerosene, light diesel oil, crude oil, benzene, toluene and other oil and chemical raw materials.The flame arrester and breathing valve can be used together or separately.
