The Tilting Disc Check Valve has a net disc type closing part, the disc rotates around the rocker shaft and is offset from the valve seat surface. When the valve flap is turned down, it is closed when it is tightly sealed with the valve seat, and when it is opened, the valve flap rises from the valve seat. Since the center of gravity of the entire disc moves only between the fully open and closed positions, and the stroke is very short, the Tilting Disc Check Valve closes quickly.
The valve disc of Tilting Disc Check Valve is a butterfly swash plate installed on the valve shaft. The valve seat is a special floating, elastic metal hard-seal valve seat, so as to ensure that the valve seat can automatically adjust the position of the valve disc.

The seat sealing surface of the Tilting Disc Check Valve is a part of an oblique cone. The sealing line formed between the seat and the disc is an approximately elliptical curve, and the angle between the plane of the curve and the centerline of the valve flow channel is 60°; approximately The long axis center of the elliptical sealing line forms an angular eccentricity with the cone axis, that is, the second eccentric included angle between the axis of the cone where the seat sealing surface is located and the center line of the valve body flow channel is 15°-20°; The axis of the valve rotation shaft forms an eccentricity relative to the axis of the cone, and is also at an eccentric position relative to the plane where the sealing line is located, forming an eccentricity.
When the pressure of the medium reaches its working pressure, the valve flap opens. When the pressure of the medium decreases, the butterfly swash plate valve flap automatically closes. Because the valve disc and the metal valve seat have the characteristics of a triple eccentric butterfly valve, this structure enables the valve disc to perform pendulum movement. There will be no friction or sliding contact during the combination and separation of the disc beveled valve seat and the funnel-shaped valve disc. When it is closed, the Tilting Disc Check Valve can quickly seal with the valve seat without any external force. At the same time, the Tilting Disc Check Valve has the characteristics of large flow and small flow resistance.
