Share(1) Scene Problems
Sealing Challenges: Gaseous media are prone to leakage, especially small-molecule gases like hydrogen, which require extremely high sealing performance. Poor sealing can not only lead to resource wastage but also cause safety accidents, such as hydrogen explosions when leaked gas comes into contact with an open flame.
Material Corrosion and Compatibility: Oxygen is a highly oxidative gas, and improper selection of valve body materials can lead to oxidation reactions that damage the valve. Different gases may also chemically react with certain materials, affecting the normal operation of the valve.
Stress Issues Caused by Pressure Differential: In gas transportation systems, there may be a significant pressure differential across the valve, subjecting components such as the valve plate and valve stem to considerable stress. Over time, this can lead to deformation or damage of the components.

Advanced Sealing Structure: A multi-layered soft laminated sealing ring is fixed on the valve plate, forming a labyrinth seal structure when in contact with the valve seat, effectively preventing gas leakage. The sealing ring material is optimized based on the characteristics of different gaseous media. For example, for hydrogen, special rubber or plastic with good hydrogen resistance can be used.
High-Quality Corrosion-Resistant Materials: The main components, such as the valve body and valve stem, are made of stainless steel, aluminum alloy, or copper alloy. These materials have excellent corrosion and oxidation resistance, enabling them to adapt to the chemical properties of different gases. For example, for oxygen-specific butterfly valves, specially treated stainless steel is used to prevent oxidation reactions with oxygen.
Rational Structural Design: The valve stem features a blow-out prevention design, ensuring a tight connection with the valve body even under high-pressure differential conditions, preventing the valve stem from being blown out by the gas. Additionally, the valve shaft is conical in design, forming a line seal with the valve seat sealing surface, enhancing sealing effectiveness and pressure differential resistance.
