Axial Flow Check Valve to Prevent Water Hammer
Product Overview:
The Axial Flow Check Valve is engineered to prevent water hammer and ensure smooth fluid flow. Its design minimizes flow resistance and manages pressure surges. This enhances both system efficiency and reliability.
Product Advantages:
– Reduced Flow Resistance: The axial flow design allows fluid to move parallel to the valve axis. This reduces flow resistance and pressure drop, leading to improved energy efficiency and lower operational costs.
– Water Hammer Prevention: This valve is specifically designed to mitigate water hammer. It controls the rate of disc closure and manages pressure changes to prevent sudden impacts that could damage the pipeline.
– High Flow Capacity: The full-bore design supports higher flow rates. This makes it suitable for systems with significant fluid demands.
– Durability: Made from high-quality materials, the valve is built to withstand demanding conditions and ensure long-term performance.
How It Prevents Water Hammer:
– Controlled Disc Closure: The disc is engineered to close gradually in response to changes in flow direction. This controlled closure reduces the impact of pressure surges and minimizes water hammer effects.
– Spring Assembly: A spring mechanism supports the disc, allowing for smooth and gradual closing. This helps absorb pressure fluctuations and further reduces water hammer.
– Optimized Flow Path: The axial flow design ensures a smooth, uninterrupted flow path. This reduces turbulence and pressure variations that contribute to water hammer.
Product Structure:
– Axial Flow Design: Fluid flows along the valve axis, minimizing resistance and turbulence for smooth operation.
– Disc Mechanism: Features a precision-engineered disc that opens and closes with flow changes. This ensures effective backflow prevention and pressure management.
– Spring Assembly: Provides additional force to control the disc’s movement, maintaining a tight seal during pressure fluctuations.
– Valve Body: Constructed from robust materials to handle high pressures and diverse environmental conditions. This ensures reliability and durability.
Design Standards:
– Design and Manufacturing: The valve conforms to API 6D and ASME B16.34 standards. This guarantees high performance and reliability.
– Pressure Testing: It undergoes rigorous testing according to API 598 and ISO 5208 standards. This verifies sealing performance and durability.
– Connection Standards: Flange connections meet ASME B16.5 standards. This ensures compatibility with various pipeline systems and ease of installation.
Applicable Media:
– Water: Ideal for water supply and drainage systems, preventing backflow and ensuring system stability.
– Oil and Gas: Suitable for pipelines transporting oil and gas, maintaining single-direction flow and protecting the system.
– Steam: Used in steam systems within industrial and power plant environments, handling high temperatures and pressures.
– Chemicals: Appropriate for pipelines carrying corrosive or high-pressure chemicals, ensuring safe and efficient operation.
Usage Locations:
– Water Supply and Drainage Systems: Employed to prevent backflow and maintain system integrity in urban and industrial water systems.
– Oil and Gas Transportation: Applied in pipelines for transporting oil and gas, ensuring safe and efficient flow.
– Power Plants: Used in steam systems within power plants, capable of withstanding high temperatures and pressures.
– Chemical Processing: Ideal for chemical plants handling high-pressure or corrosive substances, ensuring reliable operation.
Summary:
The Axial Flow Check Valve is designed to prevent water hammer while offering low flow resistance and high flow capacity. Its features, including controlled disc closure and an optimized flow path, effectively manage pressure surges. This valve is essential for maintaining the safety and reliability of pipeline systems across various media and applications.
