Summary:The utility model relates to a valve, in particular to a valve which can automatically close the water current after the water is cut off. The utility model comprises a valve body and a rotation main axle which closes and cuts off the water. The utility model is characterized in that the lower portion of the rotation axle is provided with a convex table. The water inlet in the valve body is provided with a water cut-off block used for automatically cutting off the water and a lifting lock block fixing the position of the water cut-off block. The structure is simple and novel, the cost is low with convenience and reliability. The phenomenon of water running after the water is cut off can be effectively prevented.
