Product Description

 

Breather valve

The breathing valve is a valve that not only ensures that the storage tank space is isolated from the atmosphere within a certain pressure range, but also can communicate with the atmosphere (breathing) when it is above or below this pressure range. Its function is to prevent the tank from being damaged by overpressure or vacuum, and at the same time can reduce the evaporation loss of storage liquid. It is mainly composed of valve seat, valve cover, protective cover and two groups 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, etc. When the pressure in the tank reaches the rated positive exhaled pressure, the pressure valve flap opens and the steam in the tank is discharged; When the vacuum degree in the tank reaches the rated suction negative pressure, the vacuum valve flap opens and the air enters.
