Tilting Disc Check Valve has a 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.

working principle:
The seat seal of Tilting Disc Check Valve is a part of the oblique cone. The sealing line formed between the valve seat and the valve disc is an approximate elliptical curve, and the angle between the plane of the curve and the centerline of the valve flow path is 60°; approximate ellipse The long axis of the sealing line forms an angular eccentricity with the axis of the cone, that is, the second eccentric included angle between the axis of the cone where the seat sealing surface is located and the centerline 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, it can quickly and without external force, and almost no impact with the valve seat. Sealing is achieved without collision. At the same time, it has the characteristics of large flow and small flow resistance.
Features:
1. The impact of the check valve is caused by the disc of the valve not reaching the closed position before the fluid flows back. Tilting Disc Check Valve can close quickly because the valve disc has a short running distance, so it can quickly reach the valve seat position, thereby minimizing the impact.
2. Tilting Disc Check Valve is suitable for preventing backflow of fluid in horizontal or vertical pipelines. In vertical pipelines, or pipelines with any inclination angle between horizontal and vertical, these check valves are only suitable for pipelines with upward medium flow.
3. Tilting Disc Check Valve operates automatically. It opens under the pressure of the fluid flow rate and closes under the action of gravity. The seat seal load and tightness are related to the back pressure. If the flow rate pressure is not enough to support the valve in an open, stable position, the disc and other moving parts will continue to vibrate. In order to avoid premature wear, noise or vibration of moving parts, it is necessary to select the diameter of the check valve according to the fluid state.
