The working principle of the wafer check valve

(Summary description)The purpose of this type of valve is to allow the medium to flow in only one direction and to prevent flow in the opposite direction.

The purpose of this type of valve is to allow the medium to flow in only one direction and to prevent flow in the opposite direction. Usually the valve is automatically operated, under the action of a flow of fluid pressure in one direction, the disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self-overlapping valve disc of the valve disc act on the seat to cut off the flow.

quality H71 Wafer Check Valve

The stainless steel clamp check valve belongs to this type of valve, it includes swing check valve and lift check valve. Swing check valves have a hinge mechanism and a door-like disc that rests freely on the sloped seat surface. In order to ensure that each disc to seat the appropriate location, in valve design hinge agencies, so that the disc with enough space of a swing, and real, comprehensive, and the valve seat contact. All disc can be made from metal, can be embedded in the metal on leather, rubber, or synthetic coverage, depending on the use of performance requirements. Swing check valve in the fully open conditions, almost unimpeded fluid pressure, so the pressure drop across the valve is relatively small. Lift type check valve disc is located on the valve seat sealing surface. In addition to this check valve can be freely valve movements, like the rest of the cut-off valve, fluid pressure from the valve seat sealing surface lift, medium return led to the disc back to seat, and cut off the flow. Depending on the conditions of use, the disc may be of all-metal construction or in the form of a rubber mat or ring mounted on the disc holder.
