Product Description

A breathing valve refers to a type of valve that ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, and can also communicate with the atmosphere (breathe) when the pressure exceeds or falls below this range. Its function is to prevent the storage tank from being damaged due to overpressure or vacuum, while reducing the evaporation loss of the stored liquid. It mainly consists of a valve seat, a valve cover, a protective cover, and two sets of opening and closing devices controlled by vacuum and pressure. The opening and closing device includes valve disc, guide rod, spring, spring seat, and sealing ring. When the pressure inside the tank reaches the rated positive pressure for exhalation, the pressure valve disc opens and the vapor inside the tank is discharged; When the vacuum degree inside the tank reaches the rated suction negative pressure, the vacuum valve disc opens and air enters.
