lift check valve is a valve disc along the vertical centerline of sliding body check valve, can only be installed in horizontal pipe runs with high pressure of small diameter check valve disc can be used, and spherical shape H41H lift check valve body shape and cut-off valve ( To stop valve general) , so its fluid resistance coefficient is larger, but good sealing a swing. Lift check valve working principle of the body indicated by the arrows to enter the body when the medium, the medium pressure produce upward thrust on the disc, when medium thrust is greater than the gravity disc, the valve opens. When the valve after the medium pressure forces acting on the disc and the disc before its own gravity is greater than the valve pressure forces acting on the disc, the valve is closed, to prevent backflow medium.
