The check valve can also be used to feed the auxiliary system where the pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
The function of this type of valve is to allow the medium to flow in only one direction and to prevent the flow in the opposite direction. Usually this valve is automatic operation, under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self-coincidence valve disc act on the seat, thus cutting off the flow.
The check valve belongs to this type of valve, which includes swing check valve and lift check valve. Swing check valves have a hinged mechanism and a door-like disc that rests freely on the inclined seat surface. To ensure that the disc reaches the proper position on the seat surface each time, the disc is designed in a hinged mechanism so that the disc has enough space to swing and allow the disc to make true, full contact with the seat. The disc can be made entirely of metal, or the metal can be inlaid with leather, rubber, or a synthetic cover, depending on the performance requirements. With the swing check valve fully open, the fluid pressure is virtually unimpeded, so the pressure drop through the valve is relatively small.
