About Dual Plate Check Valve:
A dual plate check valve, also known as a double door or dual disc check valve, is designed to allow fluid flow in one direction while preventing backflow. This type of check valve features two spring-loaded plates that open and close with the flow of fluid. Dual plate check valves are valued for their compact design, low weight, and efficient operation, making them suitable for a wide range of industrial applications where backflow prevention is critical.
Several essential parts make up the dual plate check valve, which helps ensure dependable functioning. The main body houses the internal components and provides the path for fluid flow. It is typically constructed from materials like carbon steel, stainless steel, or other high-performance alloys. Two semi-circular plates, or discs, that are hinged in the center and supported by a spring mechanism are located inside the body. These plates open and close in response to fluid flow by pivoting on their hinges. The spring mechanism provides a tight seal against reverse flow by guaranteeing that the plates stay closed in the absence of flow or in the presence of backflow pressure. The plates’ purpose is to reduce turbulence and pressure drop during forward flow so that fluid can pass through with minimal resistance. Additionally, the valve often includes a stop pin that prevents the plates from opening beyond a certain point, ensuring controlled and efficient operation.
Working Operation:
The dual plate check valve functions by means of spring-assisted shutting and flow-induced opening. The pressure of the fluid forces the two plates apart when the fluid flows in the desired direction, opening the valve and letting fluid through. The plates separate and revolve on their hinges, giving the fluid a minimally obstructed passage. The spring mechanism pushes the plates together in the event that the fluid flow stops or reverses. In order to stop backflow, the plates swivel back towards the center and seal against the valve seat. This quick reaction to direction changes in the flow guarantees dependable reverse flow prevention, safeguarding downstream equipment and preserving system integrity. The valve’s design enables it to function effectively in a variety of flow rates and pressures, making it a versatile solution for various applications.
