2. Applications and Performance Features
Introducing the pinnacle of innovation in firefighting technology: the Brass Check Valve for Firefighting Applications with High Power Capability. This silent check valve is designed for the demanding environments of high-rise building water supply and drainage systems, as well as fire pipeline water supply systems. It is expertly crafted to prevent the damaging effects of water hammer caused by backflow, safeguarding water pumps and ensuring the optimal performance of equipment within the pipeline. The hallmark features of this superior valve are as follows:
1) The valve boasts versatile installation options, allowing for both vertical and horizontal placement. Its valve disc moves with exceptional ease, operating smoothly with minimal noise and ensuring a high level of safety with minimal faults.
2) The design is meticulously engineered for a superbly reasonable structure and superior sealing performance, ensuring reliable operation under various conditions.
3) Built to last, this valve is wear-resistant and promises a long service life, making it a cost-effective solution for prolonged use.
3. Operating Principle
Expertly designed, the silent check valve comprises a robust valve body, a finely-tuned valve disc, a resilient spring, a carefully designed outlet, and a protective cap. Its operating principle is outlined below:
In the absence of media flow, the valve disc remains securely closed due to the pre-tension force exerted by the spring, ensuring no unwanted passage of substances.
When media flows through the valve, the media's pressure triumphs over the spring's pre-tension force, causing the valve disc to open smoothly. In the event of media backflow, the collective pressure of the reverse-flowing media and the spring's pre-tension seamlessly closes the valve disc, effectively averting any backflow issues.
