2. Applications and Performance Features
This silent check valve is mainly suitable for high-rise building water supply and drainage systems, fire pipeline water supply systems, etc. This silent check valve can effectively prevent destructive water hammer caused by backflow, protecting water pumps and other equipment in the pipeline. Its main performance features are as follows:
1)The valve can be installed vertically or horizontally, and the valve disc moves flexibly. It operates smoothly with low noise, ensuring safety and experiencing minimal faults.
2)The structure is reasonable, and it has good sealing performance.
3)Wear-resistant, with a long service life.
3. Operating Principle
The silent check valve is primarily composed of a valve body, valve disc, spring, outlet, and cap. Its operating principle is as follows:
When there is no media flow through the valve, the valve disc is in the closed position under the pre-tension force of the spring.
When there is media flow through the valve, the pressure of the media can overcome the pre-tension force of the spring, causing the valve disc to open. In the case of media backflow, the combined pressure of the backflowing media and the pre-tension force of the spring causes the valve disc to close, preventing media backflow.
