2. Applications and Performance Features
This innovative silent check valve is crafted to excel in high-rise building water supply and drainage networks, as well as crucial fire pipeline water systems. Expertly designed, this valve acts as a safeguard against harmful water hammer due to backflow, offering robust protection for pumps and other pivotal pipeline equipment. Its extraordinary performance attributes include:
1) Adaptable installation options - whether vertically or horizontally - ensure the valve disc's flexible movement. It operates seamlessly with minimal noise, guaranteeing safety and significantly reducing operational errors.
2) Ingeniously engineered for a balanced structure that delivers exceptional sealing capabilities, enhancing reliability.
3) Remarkably wear-resistant, promising an extended service life that makes it a long-term, dependable solution.
3. Operating Principle
The silent check valve's core components include a valve body, valve disc, spring, outlet, and cap. Its operational intricacies are delineated as follows:
In the absence of media flow through the valve, the valve disc remains securely closed due to the spring's pre-tension force.
Upon media flow, the exerted pressure counters the spring's pre-tension force, prompting the valve disc to open. During a backflow scenario, the combined pressure from the backflow and spring's pre-tension force seals the valve disc, effectively preventing reverse media flow.
