Description

Check valve with internal dredging function

Technical Field

The utility model relates to a check valve technical field specifically is check valve with inside desilting function.

Background

The function of a butterfly check valve is to allow the medium to flow in one direction only, but to prevent the flow in the other direction. Typically such valves are self-actuating, with the flap opening under the pressure of a fluid flowing in one direction; when the fluid flows in the opposite direction, the valve flap is combined by the fluid pressure and the self-weight of the valve flap to act on the valve seat, thereby cutting off the flow.

The existing butterfly check valve has certain defects when in use, namely, after the check valve is used for a long time, substances in fluid can be attached to the inner wall of the valve body, and then dirt is formed on the inner wall of the valve body, the dirt can not only cause the reduction of the effective overflowing area of a pipeline and the reduction of the discharge capacity, but also can influence the normal opening of the valve clack when the dirt is accumulated more, the butterfly check valve only allows a medium to flow towards one direction, the fluid only can impact one side of the valve clack and deflect the valve clack, meanwhile, the fluid can circulate below the valve clack, and then the other side of the valve clack can not be effectively impacted by the fluid all the time, so that a large amount of dirt can be accumulated on one side of the valve clack, and the normal opening of the valve clack and the normal use of the butterfly check valve can also be influenced.

In view of the above technical drawbacks, a solution is proposed.
