Abstract
A water-hammer proof and silent check valve comprises a shell (), a spring (), a flow guide body () and a cowl (). The flow guide body () is provided with flow blocking boards () which project from the outer surface of the flow guide body () and are capable of rotating around installation shafts (). A plurality of flow blocking boards are arranged in the flow passage in the axial direction of the valve, so that most part of pressure energy and kinetic energy are undertaken by the flow blocking boards by grading when liquid flows back to the valve, thus ensuring that the water hammer with large energy is divided into multiple water hammers with relatively smaller energy so as to greatly reduce the inner stress of valve bearing parts.
