A check valve generally includes a valve body, a valve core and a valve seat, wherein the valve seat is fixedly disposed in the valve body, and the valve core is movably disposed in the valve body. When the valve core is abutted against the valve seat, the valve core seals and separates two sides of the valve body, and when the valve core is far away from the valve seat, fluid can flow through the valve body. In the check valve, the movement of the valve core is controlled by fluid, the fluid flowing to one side can push the valve core to abut against the valve seat, and the fluid flowing to the other side can push the valve core to be far away from the valve seat, so that the one-way intercepting function of the check valve is realized.

However, since the flowing state of the fluid is very complex and difficult to control, the fluid not only can drive the valve core to move along the axial direction of the valve body, but also can drive the valve core to rotate under certain conditions, and the valve core can not only disturb the fluid when rotating, but also can generate large noise, thereby causing inconvenience in use of the check valve.
