Share(1) Scene Problems
1. Strong Corrosiveness: These acid and alkali media are highly chemically reactive and can severely corrode ordinary metal materials, leading to rapid damage of valve components such as the valve body, stem, and sealing surface, rendering the valve inoperable.
2. Deposition of Impurities: Acid and alkali media may contain solid impurities or crystallize during transportation, depositing inside the valve and affecting its flexibility and sealing performance.
3. Temperature and Pressure Variations: The physical and chemical properties of acid and alkali solutions change with temperature and pressure, which can negatively impact the valve's sealing and strength.
(2) Shanghai Rogers Butterfly Valve Technology and Features
1. Application of Corrosion-Resistant Materials: The main components, such as the valve body and stem, are made of special corrosion-resistant alloys (e.g., Hastelloy, titanium alloy) or fluoropolymer-lined materials. For example, in hydrofluoric acid applications, fluoropolymer-lined butterfly valves are used, with the fluoropolymer lining providing an effective barrier against corrosion.
2. Anti-Deposition Structural Design: The valve body has a streamlined internal channel to minimize stagnation and deposition of media. Additionally, self-cleaning devices are designed at the valve seat and plate, which automatically remove impurities from the sealing surface during valve operation.
3. Temperature and Pressure Compensation Function: The valve is equipped with temperature and pressure sensors that automatically adjust sealing pressure and other parameters based on real-time data, ensuring good sealing and strength under varying conditions.
(3) Solutions to Pain Points
1. The application of corrosion-resistant materials fundamentally addresses the corrosion issue caused by acid and alkali media, extending the valve's service life and reducing replacement frequency and maintenance costs.
2. Anti-deposition structural design reduces impurity accumulation inside the valve, ensuring flexibility and sealing performance, and improving system efficiency.
3. Temperature and pressure compensation functions enable the valve to adapt to changes in acid and alkali media conditions, ensuring stable system operation and reducing fault risks due to condition variations.
