Valve Body: Cast as a single piece from ductile iron, offering excellent strength and toughness with high compressive resistance and impact resilience.
Disc Assembly: Multi-disc or single-disc configuration, constructed from stainless steel with specialized rubber seals.
Spring System: Stainless steel compression springs provide auxiliary closing force to ensure tight sealing.
Flange Interface: Complies with relevant national and international standards for easy system connection and disassembly.
Noise Reduction Device: Incorporates an internal buffer chamber or sound-absorbing material to minimize noise during fluid flow and valve closure.
The flanged silencer check valve operates through the coordinated action of the valve disc and spring to achieve unidirectional flow and silent operation. The specific principles are as follows:
Medium pressure overcomes spring force, driving the valve disc to open synchronously outward. This creates a near-straight flow path with minimal fluid resistance.
01
Reverse Shut-off
During reverse flow, the valve disc rapidly closes under the combined action of its own weight, reverse medium pressure, and spring force, preventing backflow.
02
A multi-disc structure disperses impact forces, while buffer springs prolong closure time. Acoustic damping materials absorb fluid noise, keeping operational noise at low levels.
03
Spring-assisted closure ensures smooth valve disc closure, effectively reducing water hammer pressure peaks and protecting the piping system.
04
Water Hammer Protection: Spring-assisted closure mitigates water hammer and safeguards pipeline fittings
Maintenance-Friendly Sealing: Modular design simplifies maintenance with tight sealing integrity
Flange-connected silencer check valves are suitable for diverse scenarios, including:
Includes high-rise water supply, basement drainage, and fire protection systems. Prevents backflow, reduces noise, and prevents pressure loss.
Includes central air conditioning and heating circulation systems. Prevents backflow, stabilizes pressure, and reduces energy consumption.
Suitable for sewage treatment, power plants, and water treatment facilities, preventing fluid backflow while ensuring safety and operational efficiency.
