What Is The Breathing Valve Used For And How Does It Work?

What is the breathing valve used for and how does it work? The breathing valve not only maintains the air pressure balance of the storage tank and ensures that the storage tank is protected from damage when overpressured or vacuumed, but also reduces the volatilization and loss of the medium in the tank, thereby meeting the ventilation requirements for large and small tanks. Breathing valve is an important accessory to protect the safety of storage tanks. It is installed on the top of the storage tank and is used to automatically control the opening and closing of the gas channels inside and outside the storage tank, maintain the pressure balance of the storage tank, and protect the storage tank from overpressure or ultra-vacuum. Reduce the evaporation loss of the medium in the storage tank within a certain range. The breathing valve uses the weight of the valve disc to control the exhalation pressure and inhalation vacuum in the tank. When the gas pressure in the tank exceeds the allowable pressure value of the tank, the pressure valve is pushed open and the mixed gas escapes (exhales) from the tank so that the pressure in the tank no longer increases. When the vacuum degree of the gas in the tank exceeds the allowable vacuum degree of the storage tank, the vacuum valve is pushed open to suck in air (inhalation) to maintain the pressure balance of the storage tank. The above is the relevant introduction to the breathing valve. I hope it will be helpful to everyone.
