Sealing Principle of Wafer Check Valve
The sealing principle of a wafer check valve is fundamental to its operation, ensuring effective flow control and preventing backflow within a pipeline system. Below, we outline the sealing principle of a wafer check valve:
- Single Plate Wafer Check Valve: The sealing principle resembles that of a butterfly valve. During forward flow of the medium, the butterfly disc overcomes its own weight's torque through the medium's flow, opening the valve. Conversely, when the pump stops, the torque generated by the butterfly disc's own weight closes the valve. The sealing pressure produced by the medium's backflow achieves effective sealing.
- Dual Plate Wafer Check Valve: The valve opens as the pressure from the medium's backflow overcomes the torque of the spring, while closing relies on the torque generated by the torsion spring. The sealing principle mirrors that of the single plate wafer check valve, where the width of the sealing surface is designed according to the working pressure of the medium to ensure sealing performance.
In summary, the wafer check valve, with its simplified design, versatile installation options, and efficient sealing mechanism, serves as a reliable component in industrial and pipeline systems. Whether in fluid control applications or backflow prevention scenarios, the wafer check valve offers optimal performance and reliability, contributing to the seamless operation of diverse engineering systems.
