2. Applications and Performance Features
The Industrial Plastic Water Check Valve by Huhang is expertly crafted to serve high-rise building water supply and drainage systems, as well as fire pipeline water supply systems. This state-of-the-art silent check valve is engineered to effectively shield your infrastructure from destructive water hammer caused by backflow, ensuring the protection of water pumps and other vital equipment within the pipeline. Its exceptional performance features include:
1) Installable both vertically and horizontally, this valve boasts a flexible disc movement. It guarantees smooth operation with minimal noise, elevating safety standards while reducing the likelihood of faults.
2) Designed with an intelligent structure, the valve offers superior sealing performance.
3) Constructed for durability, it exhibits remarkable wear resistance, promising an extended service life.
3. Operating Principle
The silent check valve is ingeniously designed, comprising a valve body, valve disc, spring, outlet, and cap. It operates under the following principle:
In the absence of media flow, the valve disc remains securely closed, thanks to the spring's pre-tension force.
When media flows through, the pressure applied by the media overcomes the spring's pre-tension, causing the valve disc to open. During backflow, the combined pressure from the backflowing media and the spring's force prompts the valve disc to close, thereby preventing any reverse flow.
