| The breathing valve is installed at the top of the storage tank. It is a gas that solves the positive pressure and negative pressure in the tank, so that the liquid in and out of the tank is not hindered. When the external liquid is input into the tank, a large amount of gas is called out (referred to as positive pressure). If the liquid in the tank is discharged outside, the tank must be sucked into the tank from the outside air (called negative pressure). If the breathing valve is automatically closed when the work is stopped, the liquid in the tank will not leak out, so that the quality of the liquid in the tank is advantageously protected. For safe use of the breathing valve , check the flexibility of the guide and disc before use. This valve should be checked regularly (within 6 months) whether the positive and negative valve discs are flexible, and the valve disc contact surface is damaged. If it is damaged, it should be repaired immediately. After the repair is completed, everything can be reused normally. |
