breathing valve

Brief Introduction of Breathing Valve The breathing valve is an equipment 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 when exceeding or below this pressure range. Its function is to prevent the tank from being damaged by over pressure or vacuum, and at the same time reduce the evaporation loss of the storage liquid. The setting can not only reduce the gas emission in the tank, thereby reducing the pollution to the atmosphere, but also prevent the tank from being damaged by over pressure or destabilized by ultra-vacuum, which plays a certain role in promoting safety and environmental protection. It is mainly composed of a seat, a cover, a protective cover and two groups of opening and closing devices controlled by vacuum and pressure. The opening and closing device comprises a valve […]
