The main uses of a water seal tank

In the early days, leaks often occurred due to the poor quality of valve manufacturing; later, someone clever came up with the idea of using water to seal gas. In simple terms, this involved using a container filled with water as a substitute for a valve, and this method proved very effective and is still in use to this day. To date, an increasing variety of safe and pollution-free water seal tanks have been produced. These tanks have entered a new realm – they are no longer limited to use as valves only, but also serve to control air pressure and ensure safety. In chemical processing, a water seal tank refers to a custom-made pipe fitting used to maintain the pressure inside the tank, functioning in a similar manner to a safety valve. Water seal tanks can be further divided into positive-pressure water seals and negative-pressure water seals. The definitions for these are as follows: Positive-pressure water seal: When the pressure inside the tank becomes too high (above the height of the water column in the water seal), a certain amount of pressure is discharged through the water seal to prevent overpressure. Negative pressure water seal: When the pressure inside the tank is too low (lower than the height of the water column in the water seal), a certain amount of air is introduced through the water seal to prevent the tank from being damaged due to excessive negative pressure. Additionally, there is a relevant link on the forum for reference. Attachment: http://bbs.hcbbs.com/thread-118905-1-1.html (water-sealed tank).

What was said upstairs is correct; it’s an additional device designed to prevent leaks of process materials or gases, and it serves a similar purpose to an oil seal or a safety valve

In chemical processing, a water seal tank refers to a custom-made pipe fitting used to maintain the pressure inside the tank. It acts like a safety valve. Positive pressure water seal: When the pressure inside the tank becomes too high (above the height of the water column in the water seal), a certain amount of pressure is released through the water seal to prevent overpressure. Negative pressure water seal: When the pressure inside the tank is too low (lower than the height of the water column in the water seal), a certain amount of air is introduced through the water seal to prevent the tank from being damaged due to excessive negative pressure.

This allows the oil, gas, or non-condensable gases coming out of the tube to be condensed, thereby enabling separation of oil, water, and gas. The second reason is for safety considerations; for example, in a pressure reduction system, if negative pressure occurs in the tower during an accident, air may enter the tower and form explosive gases, leading to accidents. In such cases, isolation of the system from the atmosphere is necessary to protect the system
