Sanitary Fermentation Tank Air Valve Bunging Valve Water Seal Safety Valve

A water-sealed exhaust valve for beer fermentation tanks is a device used to control the internal gas pressure and release in the fermentation tank. It operates on the principle of water sealing, creating a gas barrier in water to facilitate gas discharge and prevent air from entering the fermentation tank.

The water-sealed exhaust valve typically consists of a vertical pipe and a water-sealed tank. The vertical pipe is connected to the fermentation tank, while the water-sealed tank is positioned at the bottom of the pipe. Under normal operation, the water-sealed tank is filled with a certain amount of water, with the water level exceeding the bottom of the vertical pipe.

When the internal gas pressure in the fermentation tank increases, gas enters the water-sealed tank through the vertical pipe. Due to the resistance of the water, the gas is forced to form bubbles in the water and accumulates at the top of the water-sealed tank. This bubble formation isolates the gas inside the fermentation tank from the external air, preventing contaminants from the air from entering the fermentation tank.

As the gas pressure continues to rise, the bubbles gradually rise and are discharged from the water-sealed tank, effectively releasing the gas. Once the pressure decreases, the water in the water-sealed tank refills, forming a new gas barrier.

The water-sealed exhaust valve offers the advantages of simplicity and reliability, requiring no additional maintenance. Through the water sealing principle, it effectively controls the gas pressure inside the fermentation tank and prevents interference from external air during the fermentation process. Additionally, the water-sealed exhaust valve helps reduce the spread of odors and contaminants.

In summary, a water-sealed exhaust valve for beer fermentation tanks is a device that utilizes the water sealing principle to control internal gas pressure and release in the fermentation tank. It is an essential component in the beer brewing process, ensuring the stability of the internal environment in the fermentation tank and the quality of the beer.

Technical specifications:

Operating pressure: Pressure adjustment range of 0.2-2.2 bar (1.1-3.2 bar)

Operating temperature: -30°C to +130°C

Function and Features:

This valve is designed for use in pressure vessel piping systems. The adjustable one-way exhaust valve serves to protect the vessel from excessive pressure and prevent explosions. When the pressure exceeds the set pressure (standard 1 bar), the valve opens for exhaust, and it closes when the pressure is below the set level. The adjustment rod is marked with pressure scales, allowing for precise pressure adjustment according to the desired level.

The valve is user-friendly, offering convenient operation and accurate pressure scaling. It can also meet various production process requirements, making it suitable for a wide range of industrial sectors, including food processing, beer and beverage production, pharmaceuticals, and more.
