QHXF-2000 all-weatherInstalled at the top of the storage tank, it solves the problem of positive and negative pressure gas inside the tank, so that the liquid in and out of the tank is not obstructed. When the external liquid is input into the tank, a large amount of gas is exhaled outward (called positive pressure). When the liquid inside the tank is exported, it must be sucked into the tank from the outside air (called negative pressure). If the breathing valve automatically closes when the work stops, it will not leak the liquid and gas inside the tank, which ensures the quality of the liquid inside the tank.
