The working principle, advantages, and main application fields of lined corrosion-resistant valves

Lining corrosion-resistant valve is a valve specifically designed for corrosive media and widely used in industries such as chemical, petroleum, pharmaceutical, and food. It uses special lining materials to cover the internal valve body to resist the erosion of corrosive media. This article will introduce the working principle, advantages, and main application fields of lined corrosion-resistant valves.

1. Working principle:

The lined corrosion-resistant valve includes the valve body, valve core, and lining material. The commonly used lining materials include polytetrafluoroethylene (PTFE), fluororubber (FKM), chloroprene rubber (CR), etc. When the medium flows through the valve body, the lining material can effectively resist the erosion of corrosive medium, ensuring the sealing and reliability of the valve. At the same time, the lining layer can also reduce friction and reduce the force of valve operation.

2. Advantages:

Lining corrosion resistant valves have the following advantages:

-Good corrosion resistance: The lining material has excellent corrosion resistance and can maintain stability under conditions of strong acids, alkalis, and other corrosive media.

-High reliability: Due to the role of lining materials, lined corrosion-resistant valves can effectively resist the erosion of media, maintain the sealing and reliability of the valve, and reduce the risk of leakage.

-Excellent sealing performance: The lined corrosion-resistant valve is sealed with lining material, which can effectively prevent medium leakage and ensure the stability of the process system.

-Wide application range: There are various types of lining materials for corrosion-resistant valves, and corresponding materials can be selected based on the characteristics of different corrosive media, suitable for various industrial fields.

3. Main application areas:

Lining corrosion resistant valves have a wide range of applications in many industrial fields, mainly including the following aspects:

-Chemical industry: Corrosive media are often used in chemical production, and lined corrosion-resistant valves can effectively solve the corrosion problem of corrosive media on valves and pipelines, protecting the stability of production systems.

-The petroleum and natural gas industry: In refining, natural gas transportation, and chemical product processing, there are a large number of corrosive media. Lined corrosion-resistant valves can protect valves and equipment, ensuring the smooth progress of the production process.

-Pharmaceutical and food industries: Lined corrosion-resistant valves are widely used in pharmaceutical and food processing processes, able to resist the erosion of corrosive media on equipment, ensuring product quality and hygiene.
