Application and installation precautions of breathing valves on storage tanks

As a key material storage equipment, storage tanks are widely used in modern petrochemical, pharmaceutical, food processing and other industries. 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 protect the safety of the storage tank. The following will introduce to you the application of breathing valves on storage tanks.

The function of the breathing valve: The breathing valve is a safety device installed on the top of the storage tank. It maintains the stability of the tank pressure by controlling the speed and amount of gas entering and exiting the tank. When the pressure in the tank is higher than the set value, the breathing valve will open to discharge part of the gas and reduce the tank pressure; when the pressure in the tank is lower than the set value, the breathing valve will close to prevent external gas from entering to maintain Tank pressure is within normal range.

When installing the breathing valve, you need to pay attention to the following points:

1. Install it at the center of the top of the tank, ensuring that the installation position of the breathing valve is at an angle of about 45° to the vertical line.

2. During the installation process, it is necessary to ensure that the sealing performance of the connection between the breathing valve and the flange is good to prevent gas leakage.

3. After installation is completed, testing is required to ensure that the breathing valve can work properly.

The above are the application and installation precautions for the breathing valve. I hope it will be helpful to everyone.
