the importance of breathing valves to storage tanks and their working methods

In modern petrochemical, pharmaceutical, food processing and other industries, storage tanks, as a key material storage equipment, are widely used. However, the storage tank will be affected by many factors during operation, such as changes in the liquid level of the storage tank, changes in ambient temperature, etc. These factors may cause changes in the pressure inside the storage tank, thereby affecting the safety and stability of the storage tank. run. In order to solve this problem, breathing valves are widely used in storage tanks to maintain the stability of the tank pressure and ensure the safety of the storage tank. The breathing valve is a safety device installed on the top of the tank that maintains the stability of the tank pressure by controlling the speed and amount of gas entering and exiting the tank. Its working method: when the pressure in the storage tank is higher than the set value, the breathing valve will open to discharge part of the gas and reduce the pressure of the storage tank; when the pressure in the storage tank is lower than the set value, the breathing valve will close to prevent external gas Enter to keep the tank pressure within normal range.
