2. Working Principle: Precision in Motion
The working principle of an axial flow check valve centers around its precision engineering and seamless functionality. Utilizing an axial flow shuttle structure and buffering shock-absorbing springs on the valve disc, this valve operates with remarkable accuracy.
Axial Flow Shuttle Structure: Axial flow check valves employ a precise axial flow shuttle structure with shock-absorbing springs on the valve disc for reliable operation.
Forward Flow Dynamics: In forward flow, the valve disc gracefully opens, facilitating the medium's smooth traversal through the axial flow channel.
Buffering Effect during Closure: During closure, the integrated spring buffers, preventing impact vibrations between the valve disc and body, a common challenge in regular check valves.
Swift Response to Backflow: Swift and precise, the valve disc promptly closes upon medium backflow, forming a tight seal against the valve seat to prevent reverse flow.
Innovative Seat Structure: The combined hard-sealed and soft-sealed seat structure not only prevents media backflow but also minimizes impact noise during valve disc and seat contact.
3. Design Characteristics: A Blend of Form and Function
  • Combined Mechanisms: The design incorporates shock-absorbing springs and a hard-sealed with soft-sealed seat structure, enhancing reliability. 
  • Compact Exterior: Axial flow check valves feature a compact and aesthetically pleasing external structure, ensuring both functionality and visual appeal.
  • Axial Flow Shuttle Structure Advantages: The unique axial flow shuttle structure offers low flow resistance and a large flow coefficient, positioning these valves as superior choices for fluid control applications.
4. Key Features of Axial Flow Check Valves
Streamlined Design: Axial flow check valves feature a streamlined design for fluid flow surfaces, minimizing turbulence with well-crafted flow channels, guide hoods, and valve discs.
Shock-Absorbing Springs: Equipped with shock-absorbing springs, these valves go beyond the basics, enhancing performance and reliability.
Innovative Seat Structure: The combination of a hard-sealed and soft-sealed seat structure provides soundproofing, shock absorption, and facilitates on-site maintenance.
5. Advantages of the Unique Axial Flow Shuttle Structure
Low Flow Resistance: The axial flow shuttle structure ensures low flow resistance, contributing to a smooth passage for fluids.
Large Flow Coefficient: This structure also offers a large flow coefficient, enabling efficient handling of substantial fluid volumes.
Compact Dimensions: With compact dimensions, axial flow check valves are preferred in oil and gas systems, especially at oil pump outlets.
The lightweight, fast-closing valve disc in axial flow check valves prevents premature wear, noise, and vibration. With a small mass and low inertia, it enables quick closure in a short stroke, minimizing impact force and preserving the valve seat sealing surface integrity, preventing leaks. Axial flow check valves offer a reliable and cost-effective solution across diverse industrial applications, marking a substantial advancement in valve technology.
