Characteristics and functions of tank bottom valve

Tank bottom valve is a common valve device used to store and transport liquid or gas at the bottom outlet of a storage tank or container. It is mainly used to control the outflow of materials and avoid the problem of liquid or gas countercurrent. This valve typically has the following characteristics and functions:

1. Prevention of reverse flow: The main function of the tank bottom valve is to prevent the reverse flow of the medium in the container or storage tank. When it is necessary to discharge or drain materials from the storage tank, the bottom valve of the tank will open to ensure unidirectional flow of the medium, and after closing, it can effectively prevent reverse flow.

2. Fluid control: The tank bottom valve can also be used to control the speed and amount of medium flow. By adjusting the opening of the valve, the outflow of liquid or gas can be accurately controlled to meet process requirements or processing needs.

3. High temperature and high pressure applications: Since the position of the tank bottom valve is usually at the bottom of the container or storage tank, they need to be able to withstand high temperature and high pressure conditions. These valves typically use materials and sealing designs that are resistant to high temperature and pressure, ensuring long-term reliable operation under harsh operating conditions.

4. Multiple material choices: Tank bottom valves can choose suitable materials based on different application environments and media characteristics. Common materials include stainless steel, cast iron, copper alloy, etc. In addition, there are some special materials available for selection, such as titanium alloys and nickel alloys, for media with strong corrosion resistance or extreme environmental conditions.

In summary, tank bottom valves play an important role in the transportation and storage process of storage tanks or containers. They can ensure effective control and safe discharge of materials, and prevent the occurrence of reverse flow and leakage problems. In the industrial field, tank bottom valves are widely used in various industries such as petrochemical, chemical engineering, food processing, and pharmaceuticals, playing a crucial role in the safety and efficiency of production processes.
